[silk eagle]

wait you mean you arent supposed to write the bytes to a .txt file line by line stored on an microSD card connected through a USB 2.0 dongle?

[cloud knot]

to be fair, unless we talk about super-special requirements, i would just push this through a message queue/even streaming server (like Apache Kafka or MQTT) and call it a day

[sick bronze]

Yeah but that requires more overhead, and learning their API, i already wrote a decent lib myself

[spark temple]

Yeah, but you’re requiring others to learn your way. Kafka is not more overhead, it’s one of the industry standard to use for an event based system.

I’m with @cloud knot on this. Don’t reinvent the wheel unless you have some specialized requirements.

But hey, to each their own I guess.

[cloud knot]

i mean if it is a very high throughput pipe, then yeah, a distributed, event driven solution might not be right for him. But if it is just async messages back and forth, MQTT, or if bigger needs, Kafka is the way to go

[sick bronze]

I'm not requiring anyone do anything, it's all my code :P. Also for the latest thing I've been working on, the lower the latency, the better. I started using shared memory simply to avoid writing to a database or disk every request.

As far as the "lib" goes, it's not much more than LevelDB, but in RAM.

This project is a game, kinda like Kahoot, more like JackBox. The premise is that a host connects to the game server, and all the players connect to the host using their phone. The Phone client is a web page, but the host client could be written in any language.

But I'll admit, I'm pretty stubborn. It's pretty nice knowing the entire code base myself because if there are features or issues, I can handle them myself. PHP is solid enough that if something isn't working, it's 99% on me.

Also been messing with 6502 assembly a lot too so managing memory blocks ain't that hard

Rider is a .NET IDE, that is why i linked it for you

Oh yeah I know, but for some reason my coffee-starving brain read phpstorm instead of rider.
However I just use vs, cuz that's what we use at work and I really like vs, even though it's kinda buggy often, and makes me very frustrated on a daily basis.

my brightest green squares on github are my darkest days of debugging deployment CI

Twitter · Oct 25, 2024, 2:55 AM

i still don't understand why is there no infrastructure for CI/CD systems like Gitlab (and Github too) to do test runs without need to commit the files to repository

i mean, why can't we have it like "run it on the build node, but instead of GIT checkout it would upload your lcoal files and that would be the whole difference"

[peak acorn]

nektos/act although im pretty sure it is not a flawless recreation of github actions

[cloud knot]

to be fair, i personally do this only for work, so only gitlab, which has stuff like https://github.com/firecow/gitlab-ci-local but couldn't make it work

also most of the time the CI scripts are completely different repository

[peak acorn]

I was able to get act working for my work thing but they are very very sime actionspl

[cloud knot]

so the CI in the actual project is just "import CI from another common project, and use these environment variables for that"

I literally just set 1.0.0 as version of my components when I have working initial feature set. Or usually follow the versioning of upstream when I just package some SDK into simplified API.

It's icky tho...

[neon oriole]

problem also is : people use that as an excuse not to have to deal with bugs or admitting that their solution might not be all that great... or not havving to eithter considder a better option... since everything you change in theory breaks backward compatibillity, yet they do bring new features if they themselfs like it...
and yes every new feature breaks backward compat, since downstream might be testing for that new feature not existing 😦

me personally think the whole never break userspace /backward compat is nonesense in the long term...
version A , version B-> should not break anyone depending on A, version C should not break b and have tooling to convert A to C , D should not break C have tooling to convert B to D but can break original A now , eg

people realy sticking to A should keep using A 🙂 and backport anything they want from B,C,D themselfs

and make sure every format and or protocol or type that is used in between libs or whatever has a version field 🙂 and a set of reserved parameters/space fro future use , if not only to facilitate what i mentioned above

i need help whats the problem with this? (im new to python and im using flask)

[spark temple]

Why don’t you just run the tests locally? Everything you run in a pipeline you should be able to do locally.

[cloud knot]

what is being fixed is the pipeline itself. For example i wasted a day on something which is in the FAQ/common issues for the gitlab runner, but you would need to know about it to avoid it. To be precise, i screwed up that a command to run had a pipe in it, and that pipe was not passed down as the command, but interpreted by the runner itself.

And often it is really just about perfecting the pipeline itself. Yes, i know how to build my app and it works just fine. But after that, you need to make all the "is the base system to run the build from (docker, macos computer) set up right so it has the right versions of tools, has all the SDKs preinstalled" followed by "are the right artifacts saved between the steps" followed by "are we uploading it the right way to the distribution system" and so on.

Why does mapping various vendor APIs have to be so tedious

[limpid reef]

[plush valley]

FUCK NEUSTAR

We use Neustar for various things and it's bad

We use Neustar for campaign verification and enhanced caller id (doesn't work)

Peerless uses SOAP APIs

Bandwidth uses XML over HTTP

Telnyx uses standard REST APIs but they basically aggregate carriers for you and also they suck all around

[limpid reef]

No comment. I all but shit my pants and screamed bloody murder during a screenshare meeting when they presented their "new" replacement Numbering Portal webUI in ... late 2022(?) 😦 They managed to make it open 3x as many popup windows as the old interface, have more fields you can't easily copy/paste from, and require 2x as many screens just to check the status of a number.

I don't expect a complete polished system - it's an internal / B2B tool after all, but holy hell in a handbasket, they went straight 1995 when it comes to the design and functionality of the updated interface.

[fading osprey]

of course, if they made it easy to use then any old schmuck could do it, and then how would they rake in the support fees????

(I have no experience with this company but I'm sure based off what I've heard that summary is accurate)

[cloud knot]

wait till you add GUI to the mix 😄

[cloud knot]

that could be down to legislation. Look at GovUK design system for example https://design-system.service.gov.uk/
That is down to meeting all accessibility requirements

it looks stupid for 90% of people, but the remaining 10% with vision impairment will appreciate the spacing, the colors (button goes from green to yellow when pressed), all the ARIA attributes and so on

[plush valley]

What is this that you are messing with

[cloud knot]

it is from internet, it is an integration platform, to be precise https://www.softwareag.com/en_corporate/platform/integration-apis/webmethods-integration.html

it is pretty much a server, which can publish Web Services, REST etc; and can take data from various sources and do transformations on them, call other services etc

in short, the GUI designer configures the flow of calls/transformations/etc to perform some task, so it acts something like a glue between stuff

technically it is IBM now tho

https://www.ibm.com/products/webmethods

they bought it this summer https://newsroom.ibm.com/2024-07-01-IBM-Completes-Acquisition-of-StreamSets-and-webMethods,-Bolstering-its-Automation,-Data-and-AI-Portfolios

(and yes, they made a SaaS version of it too now)

or PaaS or whatever it is called

that one looks like this

[cloud knot]

also i haven't touched webmethods for years 🙂

[limpid reef]

Oh this updated design didn't meet any accessibility requirements I can tell you that much. Fonts were 50% smaller that your browser's default with no built in way to change them, many fields / buttons had poor or no contrast against other nearby elements or backgrounds, and there was a sheer lack of consistency to the order in which you could TAB through elements so even if your screen reader worked it would sound like a lunatic designed the site. 😄

Its worse than that, they are actually more insecure.

Most carriers dont have TLS/Encryption enabled for the RTP Communication between points. Its one of the easiest things to intercept on a network.

If its analog, then its even easier with 2 alligator clips.

I had to use Japanese software at work and it was not pleasant

[plush valley]

I find this kinda funny

For a culture like japan, I wouldve (incorrectly) assumed that they wouldve been somewhat on the technical edge

[silk eagle]

i think the deal is japan is pretty culturally kind of perfectionist & bureaucratic so they perfect their existing tech and are not incentivized to work outside of the corporate structure of "boss-tells-you-what-to-do-you-do-that-and-nothing-more"

but with software a lot of it is rapid prototyping rapid development stuff which doesnt work well with bureaucracy

and with the bureaucracy it becomes difficult to, say, phase out faxes when your bosses still use faxes or everyone else still uses faxes so why be the one company that doesnt use fax

I want an explanation for "true" === "true"

[plush valley]

Even worse is doing authentication from an nginx config

I was just looking at this today

[silk eagle]

i steer away from doing my own authentication because I dont know what I'm doing so I just use oauth with google n shit then deal with sessions not the actual authentication. that way I never have passwords to lose only all the other user data

[plush valley]

I didnt even know this was possible

[silk eagle]

creativity is wasted on satan

[plush valley]

If "true" was returned as a string instead of a boolean, return false. Presumably because its assumed to be an injection attack attempt or XSS

[silk eagle]

but at least I know I wouldnt, at the very least, query select every single user in my table and iterate over them in jquery javascript shit and also unhashed passwords

[plush valley]

It shouldve just checked "true" === true which would return false.

It exists in Apache too https://httpd.apache.org/docs/2.4/mod/mod_authn_dbd.html .

Using an IDP is certianly the way to go

how useful is c?

Rn learning the language and lowkey digging it

[neon oriole]

id say while maybe were in an inbetween period were allot of code from this point forward (will be,*edit : should be / hopefully increasingly) written in more memory safe languages, C is verry usefull in terms of learing to program , and knowing it won't be a waste, as once you know one language others come allot easier and c is a verry good base as its the base for allot of languages , and cpu's are designed around it

[peak acorn]

It is prominent in numerous industries

[neon oriole]

(if you get the choice between dotnet, javascript or c , id say there is no choice 🙂 only c)

[peak acorn]

Depends on the task

[silent moon]

dang

Well i like coding in c anyway (still an absolute beginner) let’s see where i go from there

[peak acorn]

as a beginner it is a fantastic choice

because you will learn how the computer actually does things

[silent moon]

true

[cloud knot]

bare C will teach you good concepts for memory safety, but won't teach you OOP which will be required in most of other languages. For that you will have to move up to C++. But i suspect if you can do stuff in C++, you will be able to jump to any ship, i mean language. Maybe except weird languages like R, Haskell, LISP which do not borrow from C syntax/logic

what i mean that most languages are following the same logic than C/C++, but many are very different

C++, Java, C#, Typescript, PHP - in the end, they all share the similar mental model, with minor differences

[silent moon]

Noted ✅

[cloud knot]

i mean something like

the steps are pretty much identical, some syntax and API library differences, but if you can code in one language, you can quickly jump to other

for example i did some Swift iOS programming with more or less no issues within few days even tho i never looked at Swift before.

(that is, i didn't touch GUI)

[silent moon]

And ofc, i understood C++ more than java

[peak acorn]

gui programming fucking sucks

[cloud knot]

i meant more like every language/platform has their own toolkit.

Want to do native iOS programming? Learn SwiftUI/UIKit etc
Want to do native Android programming ? Learn the XML or Jetpack compose
Windows ? MFC, WinForms, XAML, lots of other MSFT toolkits, lots of multiplatform toolkits.
Java ? Learn AWT, Swing or SWT.
Linux ? GTK, Qt etc

And so on.

No wonder web based solutions are winning, when you need to learn specific toolkit for every damn platform

[peak acorn]

yeah it sucks on everything looool

That said, web based setups are the best absolutely

[weak glen]

Why learn a toolkit for every platform when we can just program in the language superior to them all--JavaScript

The dark side calls to everyone

[cloud knot]

or half way to it - React Native 😄

or the modern incarnation of the idea - Kotlin Multiplatform

[frozen flame]

ngl at least swiftui has the advantage of being cross platform (across apples platforms that is)

[cloud knot]

that doesn't count as cross platform for me LOL

[frozen flame]

i literally specified what i meant

anyways we made an ios app and it was a breeze to port it to a desktop app, we just had to modify the ui a bit when compiled for desktop as opposed to mobile

[cloud knot]

with web technologies, you make your UI once, maybe with some progressive scaling. With any other option, you need to redo the UI multiple times. This is ironically where Kotlin Multiplatform might be the best choice

https://www.jetbrains.com/compose-multiplatform/

[frozen flame]

with the work that Arc browser is doing, swift might end up being truly cross platform

[frozen flame]

which would be neat

Theyre running swift on windows for their browser right now

[keen sorrel]

wdym, swift itself is already truly cross-platform. Unfortunately, SwiftUI is closed source so there's nothing anyone but apple can do to make that cross-platform.

[frozen flame]

Arc browser is running on swift on windows

[keen sorrel]

I'm aware. So am I lol. Swift is cross platform itself

[frozen flame]

You are running a UI on swift on windows?

[keen sorrel]

Yes, just not SwiftUI because that's not cross-platform and isn't what Arc is using. They have made swift bindings for WinUI for windows

[frozen flame]

whatre you running for your ui?

[keen sorrel]

I haven't settled on using it yet, but I've used Arc's code lol

[frozen flame]

yeah exactly

which is why i said with their efforts we might get cross platform (ui specifically)

afaik they're working on leenux

[keen sorrel]

It's just my opinion, but I don't consider binding to each platform's own UI as "cross-platform UI". That's pretty much the polar opposite

[frozen flame]

baby steps

get bindings for each platform first

[neon oriole]

depends make it easy on yourself, and ask, how fast does my gui need to run code/update itself, if its for humans , well you can pick pretty slow and easy languages , that basicly reduce gui programming to connecting buttons to callers of functions (in any languages) and vice versa,,

[neon oriole]

a gui that can browse its own structure 🙂

*procedurally generated (i dont like oop :D)

[frozen flame]

Christ

[silk eagle]

this is a good example to demonstrate that gui programming sucks

personally to me hashmaps are objects and therefore that is oop

[neon oriole]

lol 😛 anything with objects is oop, 😄 thats a new one

a c-struct with pointers to both data and functions , also object and therefore oop? , so lisp is an OOP languages since it has hashmaps ,... ||datastructures in the code doesnt make it oop ||

[neon oriole]

but i also have to do a caveat here, under the hood python is as OOP as it gets,.. that doesnt mean you program OOP style if you use python... because if that actually was the factor that decided what kind of programming you did only 1 parradigm exists(on PC's (cpld/fpga is a different story)) , and that is procedural , since even the most hardcore OOP or even fuctional language like haskel is procedural under the hood 🙂

-fpga/cpld -> vhdl is a synchronous (aka tik based ) language but other than that all procedural

[north pebble]

Can anyone help me with wirting a Moq test in C#? My current test doesn't work and seems to be loading forever...

dont know much C# but if the tests are not working as expected , there might be a chance your trying to test to much in a single test and one possible solution would be to split it up in smaller chunks

[frozen flame]

me when forbiddenfruit enters the equation: >:)

anything is an object if you dig enough

and if its an object it can be forbiddenfruit.curse'd

[cloud knot]

even prototype based languages (Javascript says hello)

[neon oriole]

thats why i dont considder datastructures to be objects in the OOP sense of the word , they can be ofc . like a simple string , is an array , and to (highly simplified) print it to the screen, in procedural , you would pass the memory location of that array to your print function , the print function is also a place in memory where where all the logic to extract the data from the array , and all the logic to display it on the screen is stored . you could say ,you passed an object to the print function but that is not what object "oriented" is in my view ,... object oriented would mean the string is not just an array, but a struct , containing the array (or pointer to ) aswell as the logic to extract the data from the contained array , and the logic to display it on screen., so an int in OOP would also be a struct similar to this , but it would store different logic that instead of extracting data from an array would convert the numeric value stored to ascii , and then also the logic to display it on screen... in the oop way the actual print function that would do the heavy lifting in procedural is mostly an empty box in oop that only knows to look for a certain logic block in the struct and look for a print function in the struct and passing the outcome of the first logic it ran to the print function that it found... pretty neat concept at first glance since instead of havving to write an extremely bloathed print function that is able to deal with and convert any possible datatstructure, or struct that might get passed into it and then to display it on screen in the desired way, every type carries its own specific small convert and small print functions that only have to care about the exact type they travel with, and the print functions itslef only has to look for the specific functions in the object to make it happen...

problem is that you have to know in advance exactly what your program is going to do so you can organise everything nicely and group everythig together to share those functions (types and inheritance ) so you can write those functions in a way they work for the type and all its subclasses. you can easely forsee this to be a technical problem where you want to add functionallity that uses (partial or full functions) functions already existing in a different section of your inheritance tree, forcing you to insert a new type in a spot where there is no room for it or in a spot where it now carries all the wrong functions that have to be overwritten with the correct ones , or your writing duplicate functions that when they should change both have to be changed . but its worst problem is that it assumes that we humans are as a group[ capable of categorizing things in a consistent and sane manner , and combine that with the magic orb required to also take any future expansions into account ...

nice one to think about: i want to correctly store a fraction ,.. what is its type and what does it inherit from,... float ? well "10/3" cant be stored as a float correctly, if you have some idea , keep it in mind and apply that same logic to where do complex numbers go and what do they in herrit from in that scheme , ||ps last time i asked this one , some one went l, an array for the fraction , wich is ofcourse a procedural way of storing it not an OOP way of storing it , you have to pick a type carrieng all its operations as functions for it to work ofcourse , the actual format it is stored is non consequential in this excersise||

[neon oriole]

btw i only now just found out (* might have known this but my brain recently got scrambled a bit so, you don't know what you have forgotten ofc) but i dont think i ever noticed this 🙂 when going from 999 to 1000 in base 10 you go from 3 identical digits to 4 digits with the first getting the one increase and the 3 that were already there getting zeroed 999 1000 like obviously but same in binary (*) 999 to 1000: 111 1000 3 identical max values , then 4 . first incremented and the 3 that were zeroed , only difference : the leading `11110' in front of both
and this is for every order of magnitude the case ```

9 ->(0)1 | 10 999999 -> 111111 | 1111010000100
10 -> 10 | 10 1000000 -> 1000000 | 1111010000100

[silk eagle]

you just killed half of the people in this channel by posting that

[sick bronze]

Why, why? Are classes above you or something? Some crazy challenge?

[fading osprey]

yes

yes they are

[plush valley]

I'm going to vomit

[cloud knot]

Obviously going at style attribute is a huge abuse of capability, but the feature itself has a reasonable use case. Let's say you render a table with values, and want to highlight negative rows. You can use a class sure, but maybe you already have an indicator data attribute, so why not base the CSS selector on that.

[neon oriole]

dumb question when are we styling html we cant control ? other than on a personal machine so using stylish or smth , where frankly it doesnt really matter how horrifying the hacks are as long as the outcome suites you ?

[cloud knot]

i can imagine for example when you get portlets you can't modify, or when you are asked to change color scheme of a 3rd party intranet website you don't have sources for

but again, the example in the tweet is obviously a huge abuse of the technology. I shown you an use case where it makes sense

if you already got the data attribute, why add an extra css class to present same information, if CSS allows you to do it via attribute value ?

[neon oriole]

arent portals meant to reflect the acual site they point to so ... , and 3rd party intranet you havent resources for , well id say if it runs locally more or less just replace the css that goes with it with your own :), or just (assuming you pay good money for that 3rd party site) have them fix it upstream ?

[cloud knot]

like imagine <tr data-value="-1.0"> and then you make a CSS selector for tr[data-value*="-"]

instead of having <tr class="negative" data-value="-1.0">

[neon oriole]

<tr class="negative" data-value="1.0"> then i presume 🙂

ow wait i see 🙂

nvm

i use that on my site i think 😛 sec

            section input {
                position: fixed;
                opacity: 0
            }
            section {
                height: 0px;
                overflow: hidden
            }
            section:not(:has(input:checked)) {
                height: 0px
            }
            section:has(input:checked) {
                height: 100vh
            }

<!-- ... -->
  <nav>
    <menu>
      <li><label for="home">Home</label></li>
      <li><label for="sysinfo">System Info</label></li>
      <li><label for="manager">Manager</label></li>
      <!-- ... -->
    </menu>
  </nav>

<main>
  <section>
    <input  name="tabs" type="radio" id="home" />
    <h2>Home</h2>

    <input  name="tabs" type="radio" id="manager" />
    <h2>Manager</h2>
    <!-- ... -->
  </section>

``` okayits different but similar i guess

[cloud knot]

yes, the point of these new selector types is removal of the need to add CSS classes just to represent something which can be done through other logic.

I mean most people stopped at basic + child selectors, maybe some of the pseudo classes; sibling selector is already too confusing for many. Attribute selectors is way above the level many people think 😄

im using ubuntu 24.10 LTS and on pgadmin4 im getting this error while trying to backup my databse. ive found a work-around but no fix, any of yall know whats happening? also hi, im new here

[cloud knot]

set the path in the mentioned preferences to /usr/lib/postgresql/15/bin/pg_dump ?

[fading osprey]

^^ also worth checking that pg_dump is present in that folder, since in some distros it doesnt seem to come with postgres for some reason

[cloud knot]

on Ubuntu 24.10 it is part of postgresql-client package, which puts stuff in that folder

[fading osprey]

gotcha, good to know

[cloud knot]

alternatively you can symlink the tools one by one from the folder above to /usr/bin, but meh, that is lot of work 😄

(possibly doable with wildcards, but i am not going to try to figure that out now)

[slow coyote]

I'm having trouble hosting a website on github

[cloud knot]

did you name your file Index.html. With capital I ?

[cloud knot]

https://xavier2845.github.io/Myhomepage.com/Index.html -> rename it to index.html and it will work without need to type Index.html

(and maybe you want repository to be private ? Up to you tho )

[slow coyote]

Did this stuff earlier now I'm trying to implement a image gallery system

[nocturne galleon]

https://www.ired.team/miscellaneous-reversing-forensics/windows-kernel-internals/writing-a-custom-bootloader

[nocturne galleon]

yourusername.github.io should be the name of the repo

then your url would be https://yourusername.github.io

your index would be index.html

[nocturne galleon]

so if your username was xavier1228 on github you would make it xavier1228.github.io as the repo

you can edit your repo by going to github.dev and using their vs code @slow coyote

you can also press period on your repo to clone it to that url

[neat pond]

hello i have a rasbary pi 4 that i installd a linx software and i forgot to install a network driver and now i cant fix the ishu i need help fast it is for a contest

[neon oriole]

well funny enough its the only way i can think of (what i did) to make tabs work when the label is somewhere other than the input, and the thing to be tabbed. if you go look 90% of them all have a css dependand on the number of tabs wich is something i wont do, adding a tab should not require adding css simple, then some others you find go like
you find it more like this:

.tabs {
  display: flex;
  flex-wrap: wrap;
}

.label {
  border: 4px solid #F00;
  cursor: pointer;
  color: #FFF
 
}

.panel {
  display: none;
  padding: 20px 30px 30px;
  background: #222;
  border: 4px solid #0F0;
}
 

.input:checked + .label + .panel {
  display: block;
}
``` ```html
<div class="tabs">

  
  <input class="input" name="tabs" type="radio" id="tab-1" checked="checked" />
  <label class="label" for="tab-1">1</label>
  <div class="panel">
    <h1>1</h1>
    <p>1</p>
  </div>
 
  
  <input class="input" name="tabs" type="radio" id="tab-2" />
  <label class="label" for="tab-2">2</label>
  <div class="panel">
    <h1>2</h1>
    <p>2</p>
  </div>
 
  
  <input class="input" name="tabs" type="radio" id="tab-3" />
  <label class="label" for="tab-3">3</label>
  <div class="panel">
    <h1>3</h1>
    <p>3</p>
  </div>

</div>
``` wich means the tabbed is a thing of3 things isn sequecne not a selfcontained unit, theres also one that uses anchors but that one has the downside that when surfing to the regular html site , no achor or tab is active, or you have to write your .htacces so it reqrites anchors aswell

[graceful drift]

is this too much comments? https://github.com/Rapter001/rapters-assistant/blob/main/main.py i want it to be understandable

[fading osprey]

the link is 404

looks like a private repo

[graceful drift]

@fading osprey should be changed now

[cloud knot]

in general you don't need to comment every line, you want to comment logical blocks. And often even that is not needed, if the method and variables are self-explanatory. But if it helps you, sure, why not

[neon oriole]

golden rule write as few comments as possible , only the code that is out of place or looks weird where it is , should have a short comment for why it is the way it is , and why its there. , comments describing what code does would only be meaningfull to non programmers or to increas linecount artificially. if something took more than 30 minutes of research to get it working it deserves a comment 🙂

[silk eagle]

this is the extent of my commenting:

typically most of what i comment is math stuff so i can understand what a line is doing at just a glance 'cause my brain aint math so good

[cloud knot]

that way of checking 2XX code actually disgusts me 😄

[silk eagle]

listen, PAL. listen.

it was either this or I convert it to a string and check the first letter

this seemed more slick

[cloud knot]

if that is pythoin, then maybe if 200 <= request.status_code <= 299: ?

or request.status_code in range(200,299) ?

(maybe 199,300, not sure about the outer edges)

[silk eagle]

range is always inclusive, exclusive i think so itd be 200, 300 maybe probably

i always have to triple check when I use range()

one-off 50% of the time

[cloud knot]

anyway, about the comments.
My recommendation is to make variable names self-explanatory (even if it means you will have a longer variable name) and to make methods with self explanatory names. No need for comments when the method and variable names themselves provide the commentary

i never did anything big in python. i think the only thing i ever did through it was interfacing with some small oled screen from Pi

[silk eagle]

ive recently been trying to follow proper naming conventions in python

mostly because i've gotten tired of using variableName because then variableNameName confuses me

so I've been doing variable_name and I'm always bad with the actual case names i think its snake case and then the former was camel case

but generally I like the snake case

[cloud knot]

ha, found it !

some small code using SSD1306 library

[silk eagle]

posting that as an example of not necessarily needing comments but rather needing documentation for a function so people working on a project can just hover it and see what it does instead of jumping to the function to find comments whenever applicable

if you're going to put comments on a function rather than a line of code, best to use the reference string stuff idk what its called I forget

[cloud knot]

that ws just a random output i made back then. ah, old times 😄

[silk eagle]

example

[silk eagle]

i think I have a few of those lying around somewhere, I was messing around with pi picos a while back

[spring cradle]

i2c :o

[cloud knot]

i only used Python for this because only libraries for it were for C or Python, and Python seemed simpler for me 😄

but anyway, that is the extent of my python coding ever, few tens to hundreds of code lines.

[silk eagle]

if its meant for people then python is always great for the "rapid prototyping; rapid development" stuff

[cloud knot]

but then with my array of knowledge, i could probably be relatively effective in Python within 2-3 weeks if i really needed to work in Python

[silk eagle]

yeah its pretty much english. once you have a decent understanding of computer science you're basically already top 30% of python developers

[cloud knot]

probably the biggest issue i would have with Python would be indenting and lack of brackets

[cloud knot]

Pascal, Delphi (don't remember much of those these days tho), PHP, Java (both CLI and server side, various libraries - Struts, JSF, EJB etc), Javascript & TypeScript, some Android (Java, Kotlin) and iOS (Objective C, Swift) programming in last 2+ decades

[silk eagle]

indenting gets to be pretty intuitive, you can still organize things regardless of the indentation and there are style recommendations for line length limits and such to incentivize that neater stylization:

[cloud knot]

i use yaml so i know, it's just my brain being trained on { and } being around blocks of code. You can't make 20 years of mental training dissapear

[silk eagle]

really the indentation becomes a problem when people dont use the superior 4 space indents

you see, IDEs will convert your tabs into spaces. some people decide, "hey, what if I make my tabs 2 spaces instead of 4?" and then they put their filthy 2 space indents out into the world

and then other times you use tabs to indent in vim or something and vim isnt typically an ide so it wont convert the tabs to spaces

[cloud knot]

that reminded me of this gem

[silk eagle]

and you cant have tabs and spaces but you can have tabs or spaces to indent and thats why tabs are converted to spaces

[silk eagle]

thats disgusting and genius

[weak glen]

I feel like learning this alone made coding SO much easier for me. I guess I felt like everything had to have some succinct, sleek name when really you can just name stuff what it is or what it does. Not only is it easier to read when you need to look at it again later, it's easier to read WHILE you're writing it

[knotty python]

can someone help me with this

I am trying to do something similar but whenever i toggle the button the emoji is under the circle

nvm i resolved the problem

[neon oriole]

i see allot of python code comming out of companies and they seem to use (and so do i) ```py

def This_Varies(fn):
'''
whatever
'''
def pre_fn(*a):
return a
def this_varies(*a,**k):
A=pre_fn(a)
return fn(*A,**k)
return this_varies

also what i started to see wich i also kind of liked is the use of ```
__s  instead of self``` frees up the actual name self 🙂

[silk eagle]

my stance is yeah I could do *a & **k and yeah I would understand what it is in reading it in the future, but having it setup like that would just generally make me unhappy with the code i'm putting out

like removing rgs and wargs from the variable names doesnt really add more to what I'm doing and it doesn't make the already-python code more efficient at runtime. i could do it to try and match the conventions of companies but honestly I'd rather my personal projects have my personal stylization, its a form of self expression to me.

[civic olive]

feedback on my web design mockup? https://www.figma.com/proto/Ml4CbWmKW7JOnOAOlgVVOJ/Dawn-Layout?node-id=4-8&starting-point-node-id=4%3A8&show-proto-sidebar=1&t=VFuoY2r2Vk78AXuH-1

[neon oriole]

i find ithat if you are also handling the args in a method and storing the args in the object , eg your typing an awefull lot amount of 'args' 🙂

[neon oriole]

the only sane way with white space in programming is :

1. Indent with tabs (even if you use spaces convert to tabs in the end , since you know how much spaces you like but dont want to enforce that on your peers)
   + converting tabs to n spaces is allot easier and riskfree (when automating)
- where as (?) spaces to (n) spaces is not riskfree
+ converting spaces to tabs is also riskfree since you know what the (?) number is
+ tabs offer a better way of knowing at what level of indentation something is , since there will be one and only one for each level, nobody does 2 tabs for indent they just double the tab width)
- lines indented with tabs need context to know that verry same information since 8spaces is how many indents in ?
2. allign with spaces (same deal ),
   - tabs break allignment if you change tab width so we dont want to force our tabsize onto anyone, but we do want to keep things alligned nonetheless
- unfortunatly there is no editor i know of that lets you convert allignment tabs to spaces so you will have to get used to this if you used tabs here in the past , but its for the better (alternatively you can write code that adds this capability to your editor maybe)
+ spaces always have the same width so when spaced 4 spaces appart thing will remain 4 spaces appart and if the next line required 5 spaces to get that alligned to the 4 that wil always be 5
- (starting from row1) whereas 3 letters and a tab (width 4) will only jump forward the sice of 1 character but if 4 letters + a tab are typed the size of 4 characters is added so depending on indentation with a varying width thins may end up all over the place if you do this

my ex bos had 1 exception to this he said:

If i get payed payed per sloc , i indent with vertical tabs (tabsize 8 )🙂

[inner scaffold]

yuuhhhh first year actually coding my JavaShitScript works

[neon oriole]

lol you from the netherlands much?

[noble holly]

any reason to go with a PCIe 4 or 5 gen ssd for compiling code?

can't find benchmarks

[cloud knot]

when is storage speed a limiting factor for code ? I would say never. You should maybe look at 4k write speeds, that might be more important for you (speed of saving small files)

[noble holly]

@cloud knot compiling? pretty significant

you need to read all those files and nvme ssds were a huge speedup

[cloud knot]

but he is asking between gen 4 and gen5 ssds, So 7 vs 14GB/s.

[noble holly]

right, and those speeds aren't maintained from what I can see

[cloud knot]

and sequential speeds do not matter that much for compiling, 4k read/write does, as most of the time you read and write tons of small files, not big sequential files

[noble holly]

right, I'd go even as far as to say most text files are around that area

[cloud knot]

so look at reviews of drives which do good 4k read/write

[noble holly]

any tips? been scouring the web and can barely find anything fitting

[cloud knot]

https://www.storagereview.com/consumer/client-ssd is probably your best bet for reviews ?

[noble holly]

thank you

[cloud knot]

seems like 990 Pro is the king ?

the rest, i don't even know how to interpret those curves 😄

[noble holly]

990 pro is still gen 3 right?

[cloud knot]

gen 4

but in the end, for most NVMe drives you won't notice much difference, usually the most limiting factor for me was CPU scaling of compilation (but then i do Java & Node.js mostly, so your use case might be more sensitive to drive speeds)

[noble holly]

also Java/Kotlin and Node (plus containers/vms)

[cloud knot]

node is usually single threaded, so typescript compilation for example (or stuff like Babel/Vite etc) will be bottlenecked by CPU. In Java it depends

[noble holly]

and the other interesting parts like Rust are probably more CPU intensive

js build times are the biggest PITA tbh

10s to transpile 20k lines of TS is pretty nuts

(3700X right now, upgrading to a 9900X this week)

[cloud knot]

only 20k lines ?

[noble holly]

yeah, hobby project

don't need to touch my Angular project too much at work

so tl;dr you wouldn't invest 100€ more for a gen 4 drive?

going to repurpose my old machine for the kids and debating between buying the kids a 40€ nvme ssd or giving them one of mine and going for a new 140€ 2TB drive

[silk eagle]

well if you get paid an equivalent of, say, €50/hr (for the sake of making this math simpler) and your current compilation times are ~20 minutes and spending €100 on a faster drive would save you 10 minutes on each run, it'd take about 12 compilations to equal €100 of value in time. but also thats 10 minutes that you now no longer have to chill so there's a tradeoff here.

[cloud knot]

i am not saying don't buy a Gen 4 drive. But personally i would go for NVMe of specific capacity and then pick based on price. Gen 3 vs Gen 4 vs Gen 5 most likely will make minimal difference imo

[noble holly]

thanks

[neon oriole]

python takes quite a while to compile to 🙂

[hardy bane]

how do i properly post code here without it being normal text or an image

[silk eagle]

put `'s before and after

tilde (~) squiggly lines but not shifted idk what they're called the tilde apostrophes not normal apostrophes

[spring cradle]

backtick/backquote?

[silk eagle]

that sounds familiar so probably that, might just be ticks

[silk eagle]

example:

def example():
  return [x for x in [not hex(bool(not x)) for x in [z % 2 == 0 for z in range(0,8)] if bool(not x)]][1:(len(__file__) // 2)][False:-True][0]
if __name__ == "__main__":
  print(not bool(bytes((example().as_integer_ratio())[1] * 2)[__name__.count(str()):False] != 0 != 1))

[spark temple]

It’s not a compiled language.

[neon oriole]

it is ... it just also has in interpreter , but you can compile it to a binary as i demo in the gif ...

[spark temple]

Never worked in python but my understanding is that it was an interpreted language.

[neon oriole]

you can transpile it to c since its cpython after all so , and you can compile that c code

[spark temple]

I mean, most languages are built on C. lol

[neon oriole]

but most people dont because you dont have to but there are allot that do to, like big parts of Ableton Live are written in python and they just compile and ship binaries

[neon oriole]

no cpython is the c implementation so it uses c runtime eg , the interpreter is written in c, so in the end when running a python program it gets converted to bytecode like java and then executed , but you can just as easy not go the bytcode -> interpreter part but code -> c-code(with allot of overhead) -> binary https://nuitka.net/

most langs are ont dependant on c (even allot of them do require it lol , here goes my argument) what i think you mean is that languages evolved from c, but langs like haskell and ocaml technically can do without c runtime

[loud storm]

anyone here?

[frozen flame]

Python gets compiled to byte code so that's technically a compilation step

Beyond that things like nuitka exist to turn python into c code yeah

[peak acorn]

what moron in charge of json decided to not let you use underscores or something inbetween numbers 🤷‍♂️

dangling commas at the ends of things as well would be good I think

[cloud knot]

what do you mean by "inbetween numbers"

[peak acorn]

1_000_000

[sick bronze]

git gud

[cloud knot]

i don't get it. Why would you put a number as not a number, but as weirdly formatted string ? Use string type, if you want to send strings. Or number type, if you want to send numbers. What you show is not a number, thus put quotes around it, and you are done. You can use any character then. "1$000$000" if you wish

[peak acorn]

its used all the time when writing big numbers, the whole point human numbers are written like 2,147,123

[cloud knot]

xs:decimal in XML Schema would kick your but for that type of 'number string' as well

[cloud knot]

but again, why do you want a transport/data format to deal with formatted numbers instead of the actual numeric value ?

It is not JSONs job to be a formatting tool

[peak acorn]

yah i mean obviously the right thing is i use a proper config file format

[cloud knot]

most formats deal with numbers as numbers, not formatted numbers. Is 1,000 equal to 1000 (USA) or 1.000 (most EU countries) ? That is why numbers are represented with decimal dot and no thousands separator, as that is formatting specific thing which doesn't belong into a data exchange format. You want formatted values, then use them as formatted values => strings

or make your own parser for your 'custom JSON with _ as thousands separator'

[peak acorn]

most programming languages will take underscores

[plush valley]

hwat

_ as a delimiter?

Also why would you have a number defined as a string and formatted first? Why not just format it as it gets processed and displayed to a user (if it does)?

As suboptimal as it gets

[silk eagle]

i feel like ive seen _ delimiters for numbers in a language somewhere and it was scarring enough to be in my brain somewhere as a core memory i forget where though ill do some digging

it might be python actually

i remember it was used when storing big numbers in code somewhere while having it readable but not for data transfer

yeah makes sense that it was python, readability thing.

although this is fundamentally different, in my opinion, from using delimiters in JSON files

[modest tartan]

what programming laguge should i learn first i want to learn c# c++ and python

and what is the best way to learn for free

[silk eagle]

start with C#/C++ and then youll be able to learn python super easily.
best way to learn for free i would say:

1. find some videos on the fundamentals, if it's your first programming language you'll want to familiarize yourself with variable types and general CS knowledge helps, stacks vs heaps, how bytes work, what a compiler does, etc.
2. make some little projects to start - calculators, programs that read text/json/xml/csv files, do some googling to help out.
3. increase complexity as you learn and try to keep challenging yourself.

[cloud knot]

but then again, we are back to:

1. put it in JSON as string, parse it yourself, deal with invalid values yourself
2. make your own RuggsJSONVariant parser, which allows numbers to have _ as thousand delimiters in numeric values

as i said before, i have yet to see an exchange format which allows this. JSON doesn't. XML doesn't.

[silk eagle]

well no im saying its in python. python seems to ignore the underscores so they can be used as a delimiter for readability. data formats cannot ignore the underscores very easily because they arent interpreted consistently (that is - every implementation of reading a JSON file would have to be changed which isn't feasible at this point) or compiled.

[frozen flame]

there were a lot of spicy conversations before the core devs even considered adding it

and realistically ive yet to see a valid usecase for hardcoding such big numbers

[modest tartan]

Could I just do the free Harvard cs50?

[silk eagle]

yes cs50 is perfect for that imo

i did cs50 way back in middle school when I dropped out (to be homeschooled but technically this was done illegally and not properly at all), cs50 was basically my 7th/8th grade curriculum

[modest tartan]

Only issue is that I need someone there making sure I pay attention the entire time

[silk eagle]

well typically people get a rubber ducky to explain stuff to but i dont see why you couldnt instead get a rubber ducky to give it a handgun to intimidate you

[neon oriole]

i would not do c++ or c# , but just C instead , possibly on for microcontrollers to get the basics right

[silk eagle]

this is fair but also its hard to expect people learning this stuff to have even the slightest idea of how to go about writing stuff for microcontrollers. keep in mind, average person doesnt know what an IDE is.

jumping that far into the deep end will scare away most people who are just trying to dip their toes in and see what they wanna do since not everyone is gonna be a 1337 20D3R 10Xer (that is to say some people prefer a different pace at different places in the stacks and its important they find out where they wanna go before they burn themselves out on learning how to make their esp32 flush a toilet)

id be so fired there

[plush valley]

Theres this one PR someones been working on for 2 years

Its a massive rewrite of some core shit

[cloud knot]

that length of feature development/PR would be only brand new project/full rewrite - but even those would be commits/PRs against a separate branch.

I mean sure, i have days where i fix multiple reported bugs in 15 minute cycles (read the bug report, bug is obvious, fix one line, test, commit), but more often than not the cycles are full days (1-4).

[frozen flame]

i mean yeah i'm developing a push notification server from scratch that properly integrates with the rest of our setup and properly handles scaling to huge loads

[midnight wind]

kinda funny how in my job PRs mean problem reports

don't want PRs

Been working on this, this weekend

[torpid relic]

Starting a new channel, just to talk about homelab and development. So I made a quick nodejs app that registers usb devices and copy the files inside of it directly to my NAS. So I can just plug it on a usb hub dedicated to my ProxMox instance and it will offload all the raw iPhone 15 pro log footage recorded on an external ssd very quickly 🙂

It also sends nice progress messages on Telegram.

[peak acorn]

whats ur personal use case for this?

oh iphone 15 video

[torpid relic]

Yep. Helps to get all the iphone log footage into my Nas (I edit all the videos directly from it)

That way I can saturate the nvme speeds on both ends 👍

[cloud knot]

man, i love the way Apple's CDN caches Apple Developer documents 😄

for context, it is this page https://developer.apple.com/news/upcoming-requirements/ and the page literally puts text in and out depending on which cache the browser hits

[silk eagle]

I just saw something in my email that looks like the most wild and elaborate SE attempt ever

im assuming how this worked is they:

1. created fake linkedin job postings to get applicant emails for specific positions
2. created a fake business website and sent emails about setting up interviews (to a company I never applied for) with generic openings on their /careers/ page for literally every single position you can think of
3. office addresses on their site as addresses in large cities with no suite #, floor #, etc, and the buildings are typically a retail store completely unrelated to the fake business (not even a ghost-mailbox like I expect)
4. end goal is I guess to get either personally identifiable information or to get enough information for identity fraud or such

and the domain being registered a month ago seals it for me

[steady dawn]

[rancid nimbus]

Hello, stupid problem. I have a python module I am attempting to install on the system level. I see it has an import imp which is deprecated and does not work on python 3.12. What is the best way of fixing this?

[simple temple]

man chatgpt is incredible.

I like download managers for bandwidth limiting but dont need literally anything else from them, so I looked into aria2 and heres what I came up with as a way to run it conveniently.

#function dlfilelimiter {
#    aria2c --max-overall-download-limit=2M 
#}
#Set-Alias dl dlfilelimiter

so I give it this dumb alias and tell it, "can you revise this to wrap the url I paste in quotes"?
it makes this

function Download-WithLimit {
    param (
        [string]$url,
        [string]$speedLimit = "2M"  # Default speed limit of 2MB/s 
    )

    # Ensure aria2c is installed and available
    if (-not (Get-Command aria2c -ErrorAction SilentlyContinue)) {
        Write-Host "aria2c is not installed or not in the PATH." -ForegroundColor Red
        return
    }

     # Remove any accidental leading or trailing spaces from the URL
    $url = $url.Trim()

    # Build the aria2c command
    $aria2Command = "aria2c --max-download-limit=$speedLimit $url"

    # Execute the command
    Write-Host "Downloading from $url with a speed limit of $speedLimit..." -ForegroundColor Green
    Invoke-Expression $aria2Command
}
Set-Alias dl Download-WithLimit

thats nuts just how well it interpreted what I wanted from the alias. And made this modular and error checking script for me thats better in every way

thats just so cool, this thing can really enable a code illiterate idiot like me get a taste of the life of a poweruser

Thoughts https://codepen.io/Oscar-the-lessful/full/jOggRxW

[silk eagle]

the little circle boxes with stuff in them beneath the "Start Learning" button make me uncomfortable (why do they exist and also why do they have an effect when I hover them). the arrow in the bottom right to scroll to top doesnt go away if you're already at the top. i like the idea of the background having some color but tbh that shadow thing looks like someone sat on blueberries and it makes the center button (and "GCSE" text when it wraps) have uncomfortable contrast. also center button should probably have cursor: pointer

i think the light purple + outlined text makes the GCSE hard to read and this is a bit clearer to see when you look at it with adjusted contrast (this is +40% contrast where the text is basically invisible)

also not a designer so this is just my nitpicks

[tardy willow]

Thank you.

My goal for the circles was to show the relyable and budget service provided.

[weak glen]

Also, I believe you want to drop the apostrophe in "GCSE's". I could be wrong of course but I think that would make it look more professional. You might even want to drop the "s" entirely(?) but I'm not as sure about that one...

[tardy willow]

you may be right on the apostrophe but the s i think is correct as you take multiple GCSE subjects

HDD going fast

[plush valley]

Well the question I now have is why are you holding open a db connection for that long if its idle

[silk eagle]

it's accessed once a week but that access needs to be as fast as possible because that connection syncs the system clocks across every machine in the hospital and the software for life support systems doesnt work if the clock doesn't match 'cause the hospital is trying to meet green energy guidelines by 2035 so it contacts a 'master clock' dell optiplex in the basement to see if it should still run this second. and they dont use a time server because their proprietary OS doesnt support NTP (they sync their clocks via postgres (the time is stored as a string of letters that has to be converted to unicode ordinal values which adds up to a unix timestamp))

[plush valley]

Ive been using React + Vite for quite some time. Ive been thinking about moving one of my projects over to vanilla js + vite but I just know I'll end up writing a very simplified framework to make that possible in the process. Any frameworks/libraries yall use for client side rendering and/or hydration?

For context the project im rewriting I did so back in mid 2022 and made some choices I regret (ie using react-maps-gl instead of just using a useRef() with maplibre-gl). My skill has improved quite a bit so I was planning on rewriting the site anyways (less so for performance reasons, more so for ease of development) and thought that possible also using a different framework in the process might be a good idea (the only other framework I have used majorly is Vue, which I do through a contracting gig I have)

[cloud knot]

have you considered modern Angular ? 😄

they added deferrable views in Angular 17, now in Angular 19 they added developer preview of incremental server side hydration etc

[slate pecan]

Ive thought about using Angular, I'm just not 100% sure how much (or if) switching to another framework would be a benefit. Ive used it in the past and TBH its syntax does make me go "huh". Also tbh im not planning on doing any sorta server side rendering to keep my costs as low as possible.

[cloud knot]

just a note, zone.js is gone, now they got signals, effects etc https://angular.dev/guide/signals . RxJS is still a thing, but it is a choice for some use cases where signals can replace it

does someone have a guide or something to setup a C/C++ developpement environement in Linux ( WSL Debian( terminal only), and Raspberry pi 4) .

Yeh. Im well familiar with it

I ended up not adapting to it very well.

But I will admit it can be a very pretty (by means of minimalism) text editor and the community around it has made it into full blown cross compilation IDE levels

[fading osprey]

neovim is a solid editor if you actually put in the time and effort to learn how to use it. I say this as someone who has been putting in said effort and actively enjoys using neovim, aside from the occasional hiccup forgetting how to do something (or just not knowing and wanting to find out) in which case, a quick google search and you're back on track

not having to move my hands off my keyboard is a big win though, especially when I can do almost everything without moving my hands around the keyboard to press function keys for example

- No NOTIFY ("ERROR: Function pg_notify not supported")
- No nested transactions
- No JSONB

What, what IS it compatible with?

no views, no sequences => not a database

i mean sure, some of these things are hard on distributed database, but still, it is not mentioned

"behaves comparably" yeah, if you dont want to use any of the real features of an actual database

[silk eagle]

saying they have identical behavior for "most supported features" but not json(b) is crazy

'yeah by the way the db doesnt support integers, you have to put them as text and then convert to int whenever you use the value'

https://docs.aws.amazon.com/aurora-dsql/latest/userguide/working-with-postgresql-compatibility-unsupported-features.html
No

it's literally just a PostgreSQL wire protocol compatibl nerfed SQL database unable to do majority of basic SQL features. But hey, it's distributed

alsoi tough luck if you want a different charset than UTF-8 (not that big deal), and C collation (RIP)

A transaction cannot modify more than 10,000 rows, and this limit is modified by secondary index entries.

[silk eagle]

you can also only have one db per cluster

[cloud knot]

in short, it's a joke unless you really need that distributed feature and you don't need any advanced features and never query big datasets

hello
I was wondering if In Visual Basic
im trying to make a script that gets the inputs from the user and saves them in a 1d array
then I want to make a checker thing that sees if that value is already in the array (duplicate)
I’ve tried putting “if numslist(I) = numslist
but I have no clue more than that
thank you

[drowsy elbow]

vb classic, or vb.net?

You could always change your array to a System.Collections.Generic.HashSet<>. This is a collection, which has the "Add" method. It will return a boolean which returns true if it is added, and false if it was already in the collection.
This is assuming you're using vb.net

I'm writing an android app which has a tts feature which receives messages from a server.

I'm testing it out in my emulator and the tts worked fine. However, when i install the app on an android box to connect to my tv, the tts acted really weird; delays, lower pitch, audio cut off sometimes, then the pitch and speed ramps up after a few consecutive messages. This issue doesn't happen when i connect a small usb speaker to the android box or pass audio to my laptop via adb. As far as i tested, it only occurred on the hdmi output. I'm guessing it's the sample rate or bitrate being higher than the box can process smoothly? If so, is there a way to config my tts in code to reduce the audio "quality" maybe, to fix this issue? I already have pitch and speech rate set in codee

ever had to deal with Meta APIs? I've got a webhook for WhatsApp Business and Meta's servers sometimes resend messages for no good reason without the person that wrote the message doing anything

... oh i'm seeing those requests they made had status code 499... that'd explain why meta resends the message since it believes it was never processed by us... but that would mean that the server must've taken too long to respond or the Meta Servers being impatient af

[neon oriole]

by whom, i know companies who actively are searching for young people to learn cobol just so they can convert that code to something new and they cant find any, they even dropped the "some programming experience required" from the requirements and are basicly offering you a full time pay to first learn cobol and then a second language (forgot wich one it was they wanted to convert to wasnt c ,c++ or python i would have remembered that ) and according to a video i saw recently: https://www.youtube.com/watch?v=qNytWcW38us ,would suggest that its still actively maintained 24/7 otherwise the thing collapses 🙂

[crisp talon]

Hey you guys 🙂 - Question: Are there any courses on YT or Udemy that you guys can recommend on "Getting started with GitLab and migrating projects to it and learning the pipelines" from a Dev/Admin perspective?

Context would be:
Having Bitbucket or Github as a base with totally different deployment-files and learning the basics in GitLab, learn to pipeline and to restructure all this. Wishfull would be focus on the topic and not like 1 hour off-topics on how to setup AWS and Environments on random Cloud-Providers. Would be hosting GitLab myself as the CE/EE-Free-Tier version.

[drowsy elbow]

I'd learn more about Docker, and third party CI/CD platforms which you can self host. Using Gitlab, Github, Bitbucket, or whatever, only locks you in their eco-system. But that's just my opinion.

To awnser your question, I would learn how Gitlab's pipelines work, try to migrate a smaller project, and then work your way up more complex applications.

[crisp talon]

Im looking specifically for this, i do Docker since 2015 and know other CI/CD platforms already, but i wanna learn GitLab in a structured way

[neon oriole]

what does git mean with ```
CRLF will be replaced by LF the next time Git touches it

[fading osprey]

it means that rather than your file using CR + LF to indicate a line ending + new line, it will use the LF character instead.

CR is Carriage Return - used to return the cursor to the start of the current line
LF is Line Feed - used to append a new line below the current cursor position.

windows likes to use CRLF as its line ending convention, whereas most unix-compatible systems use LF, git being made by Linus, original writer of Linux, which is a unix-compatible OS means that git also prefers LF convention over CRLF, and so it will replace CRLF with LF to minimise the number of changes your commits generate, you can change this in the git config but I don't recall the command off the top of my head

Hope this helps 🙂

[cloud knot]

not much more there to it than the official documentation https://docs.gitlab.com/ee/topics/build_your_application.html, plus possibly helper stuff like https://buildah.io/

[cloud knot]

my best recommendation is to create a separate pipeline project which does contains the CI stuff, and then your actual project only has a small .gitlab-ci.yml file which includes the requested build pipeline from the pipeline project:

include:
  project: pipeline/project
  ref: branch/of/the/pipeline/project
  file: path/to/ci.yaml

this way you still run the pipelines in context of the actual project, but every CI/CD related artifact outside of CI variables set in project settings is inside the CI/CD project instead

[hollow aurora]

aws vs digitalocean for static website?

[midnight wind]

cloudflare pages works great for free

[crisp talon]

Thanks for the idea, but im looking for a solution for 15+ people that enables them to have ground-work knowledge to talk to each other and have the same basic knowledge as well as giving them the ability to have the same wording when they talk about stuff. I know the official doucmentation is really good, but not everyone learns the same and reads the same sadly.

[cloud knot]

not really sure what you are after then. Tutorials ? Best practices ?

[crisp talon]

Something that helps "unknown dev/admins to the Topic GitLab" to migrate from another CI/CD system and git away. Giving them the basics and the learning how to construct the new pipepiles in yaml and register project-based runners and whatever a dev/admin in learning needs to be able to be educated.

[crisp talon]

But Yeah, Tutorial+Best-Practices surely would help

[hollow aurora]

ok..thanks

[hollow aurora]

and for Saas based applications?

[limpid reef]

Depends on what the SaaS website is doing and how it's written. VPS's like Digital Ocean or Vultr are a great place to start messing around with your code in the real world, but if your SaaS website is overly complex you may end up needing to go with something more performant.

[hollow aurora]

SaaS based apps are more like ERP

[limpid reef]

They could be. They could be a server management panel, an invoicing solution, or even a platform to resell other SaaS services!

[hollow aurora]

so suggestion is to test it on VPS before deploying full scale on other services?

[limpid reef]

Suggestion is to always rest your code. How you test it depends on the code's requirements.

here is my regex: /(?<=\n|^)(\d+(?:\.\d+)*)(?=\s)([\s\S]*?)(?=(?=\n\d+(?:\.\d+)*\s)|$)/gs

it's designed to capture data formatted like so:

1.1 (Insert header here)
(insert body here)
1.2 (Insert header here)
(insert
body
here)
1.3... Ect

In my regex101 tester, it works totally fine!
In Typescript, using es2018, it doesn't match anything at all. Removing "(?<=\n|^)" results in the first set of numbers to matching to match[1], while the second capture group containing the ENTIRE rest of the body.

What am I doing wrong?

// Read the contents of the input file
const data: string = fs.readFileSync(inputfile, 'utf8');

// Adjusted regex pattern to capture number sequences and text
const regex = /(?<=\n|^)(\d+(?:\.\d+)*)(?=\s)([\s\S]*?)(?=(?=\n\d+(?:\.\d+)*\s)|$)/gs

// Define an interface for the JSON object structure
interface JsonObject {
    number: string;
    text: string;
}

const matches = data.matchAll(regex);

const jsonObjects = [];

for (const match of matches) {
    const jsonObject = {
        number: match[1],
        text: match[2].trim()
    };
    jsonObjects.push(jsonObject);
}
// Write the JSON string to the output file
fs.writeFileSync(outputfile, JSON.stringify(jsonObjects, null, 2));

console.log('The data has been converted to JSON and saved to the output file.');```

I will be of no further help as I left programming behind when the Javascript wars began in 2012, but I'd wager a guess the issue involves how "Positive Lookbehinds" work in certain browsers / languages.

• https://stackoverflow.com/questions/3569104/positive-look-behind-in-javascript-regular-expression

[jade crane]

TLDR: regex101 is lying to me

D:

[limpid reef]

Uh, no? It's just not giving the same "warning" that regexr.com provides...

[jade crane]

I understand that, I think I mostly mean that I wish it did haha

It's very odd still becaue, lets say I use /(\d+(?:\.\d+)*)(?=\s)(.*?)(?=(?=\n\d+(?:\.\d+)*\s)|$)/gs

From what I can tell on regexr.com, it captures all the groups I need as I need them. Yet, in my code it doesn't appear to get any matches

Also I appreciate the input, even if you don't want to help with JS/TS related things :P
I'm puzzled.

ha. It worked first try with the same REGEX in Python..

[silk eagle]

(screenshot from https://regex101.com)

bunch of different implementations of regex which occasionally have inconsistencies

and i think sometimes different browsers can have different behavior if its being processed in the browser

[jade crane]

I tried them all, I assumed EMCAScript worked since it says JS but 🤷‍♂️

[jade crane]

It's not even running on the browser, just a basic VS ts-node call to run it in console

I'm using TS as just a scripting language cause I'm weird

[spark temple]

So, not sure I’m really understanding. It looks like you’re just trying to append the picture you want to the body?

You can do something like;

var allImages = document.getElementsByTagName("Imgur");

for (i = 0; i < allImages.length; i++) { 
  allImages[i].src = “path/to/image”; // Now this can be a remote image you reference to or it has to be a path relative to the site you are on. Or there could be a path relative to the Chrome plugin you are building (haven’t done this but would lead you to what you’re looking to do).
}

[silk eagle]

I think the idea they have is to overlay an image on all the images on a page

and the image path is not being found (although they are using the correct method to get a relative file path for the chrome extension: https://developer.chrome.com/docs/extensions/reference/api/runtime#method-getURL)

[spark temple]

The issue is in the manifest.json.

[silk eagle]

towards the end of your log file I'm seeing:

img.onerror @ content.js:8
invalid/:1  GET chrome-extension://invalid/ net::ERR_FAILED

and looking into it, you might not have permissions to access a .png resource with the extension,

"web_accessible_resources": ["*.png"]

in the manifest.json may fix it

[spark temple]

You can’t just say <all_urls>

https://developer.chrome.com/docs/extensions/reference/manifest/web-accessible-resources

[silk eagle]

under host_permissions I think you can: https://developer.chrome.com/docs/extensions/develop/concepts/match-patterns#special

[spark temple]

Ah, it’s under the special cases. That’s weird.

But regardless, not seeing a file being referenced in the manifest.

Can just set the resources in the web_accessible_resources object.

So I'm currently in the process of making a MvM-inspired Online PvE game (Still very early. Only a very basic prototype & some conceptuilization stuff done ATM)
1 of the main things I'm trying to figure out from the very start is optimization. 1 of the main appeals of this game is its an online multiplayer game that could run on basically anything. Any cheapo Computer/Phone/Rasberry Pi, most retro consoles (As long as they have SOME way of connecting to the internet), most random smart appliances, etc. Basically the kind of game Bringus would LOVE. But even still, the game will still be 3D in movement (Think smth mostly along Hack n Slash or 3rd Person Shooter, depending on the class being played), so...how would I get it to look aesthetically pleasing across so many generations of hardware with the limitations of the less powerful gens in mind most, without any of the visual jank games from said gen tend to have? I do have a general aethetic direction/theme, but as for translating that into in-game visuals...I'm at a bit of a blank

Could someone give me a hand later tonight with c# project I’ve been working on. I’m stuck on one part but have everything else working fine

[runic drum]

how hard would it be to make a programming language?

[agile rain]

I'm looking to learn a new programming language. I currently know PowerShell and I know the next logical step would be to learn C#. But I want to move away from Windows/Microsoft based development to a FOSS & linux-based/OS-agnostic development. I hate Microsoft with a burning passion and am trying to remove it from my life as much as possible.

Should I side-grade to Python, or should I learn a lower level language? If so, what lower level language? Rust?

Most of my work (https://github.com/alexlarner) has been in SDK & API creation for use in larger automation, which I also build. I prefer backend/command-line tool development.

[red mulch]

..... But you don't know the first thing about it

What is your language going to do? What makes it different?

[runic drum]

It is specifically going to by for game development and will be simple to understand and write

[red mulch]

Specifically for game development? What makes it specific to game development? How will it be simple to understand?

[runic drum]

It makes it specific to game development as it can only be used in a game engine. It will be simple to understand as it will have very simple syntax which looks very similar to English

progress on my part price scraper version 9000

1. error dumps (pictured is not a typical error, that's non-critical and I typically just use the error dumps as a good way to see when CSS selectors may be invalid for a vendor). this project uses playwright, occasionally I might run into issues that would be best solved by having screenshots of the page when they happen so there's also support for that (not typically used here because its not very performant)
2. big ole logging (this was a grievance of mine from my last version of this project)
3. super dynamic kwarg'd (sort of) selector setup for vendor configuration. I have, for example, selector types like price, misc_price, & additive_price. selectors of type price will overwrite the listing's price. so if I have, say, the "main" price, then a "after discount" price, whichever is configured latest will overwite the previous. or if I have a shipping price/etc that I want to add to the listing's main price, I can set it as an additive price which would parse the price from the element and add it to the final "main" pricing. and misc_price just parses a price from the element and tracks it separately

...which all ultimately results in an output like this:

one roadblock with keeping track of shipping prices is that 99% of retailers will have the shipping price change depending on your region because thats how shipping works. so i've pivoted that into just a "yeah its free shipping" indicator

Is here a dev that want to learn and get paid a bit to help my fivem server back up it got nuked by a child dev I would appreciate it

[white pecan]

Python would be good for learning more programming design and higher level concepts. Or I would learn C

Do not jump to c++ unless you're ready for a lot of crap. Imo, you should learn C first to learn the basics of memory management, data structures, not using oop design. Etc

[white pecan]

I don't have much experience with fivem, but I do have devops and a lot of developer experience. What's up with the server?

[zinc lynx]

It got nuked backup is from last night so tables are mostly gone

[white pecan]

What is it hosted on? And what's your budget for hosting costs? I think more backups are in order.

I'd recommend an hourly local backup and a nightly off-site.

[zinc lynx]

Uhm it’s not a server server it’s a fivem server

[white pecan]

Ohhh, you have to have it hosted by one of the approved providers right?

[zinc lynx]

No that’s no problem but it’s a vds

Most problems are like tables that are need to be added to the database idk a lot about that

[white pecan]

I see, intriguing.

[white pecan]

Tables as in Lua tables?

[zinc lynx]

Yes database tables

[white pecan]

Should be as easy as sshing into the vps and mv all the database tables into their respective directories?

[grim flint]

its not too bad, although it can get exponentially more complicated as you go beyond "functions" and get into "genuinely good" territory 💀

https://craftinginterpreters.com/ is a pretty good place to start (note: scroll down to see the web version for free), it actually builds the same language twice but in two different ways

both versions implement "interpreters" for a language called "Lox" that the author of the book invented.

1. first one is a trivial "tree-walk interpreter" that just parses and then directly interprets the program, it's slow but it's also stupid simple and gives you a mental model for how a language actually works internally
2. the second is a bytecode compiler/bytecode interpreter that is closer to how most real interpreted languages work, performance isn't a huge focus but this approach is far easier to optimize than #1

https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/index.html is also pretty good, although it does assume you understand some of the basic parser theory already (which the first book does a very good job on). It builds a simple LLVM frontend for another author-invented language, this time compiling to LLVM IR (which is then compiled to target-specific machine code by the LLVM framework)

beyond that, textbooks are your best bet for fully DIY compilers

your first language is going to suck, and if you keep at it you might have a decent language by your third or fourth real attempt 🙃

its incredible for learning though

Hello guys. Anyone can give insight on how to setup an email using a subdomain as address?

[frozen flame]

The same way you set it up on a main domain, but point it at the subdomain instead

The email server isn't tied to the same subdomain (usually people have mx1.domain.com as their email server, while using @domain.com or any other subdomain)

[cloud knot]

having said that, own SMTP is pain when using for email, you will sooner or later get banned by big boys

you should be fine if you have dmarc and co setup correctly and aren't exploitable for sending spam (open relay etc). I run my own mail server for about two years now and every thing is fine

experimentation about combinig pc funcionalities to enchance performance of the pc? some being?

[silk eagle]

if you shake the PC itll jostle any rogue electrons stuck in the carbide rails which increases the induction capacity of the real-time ray traces.

also, if the PC is upside down, the fluid in the capacitors can situate at the top and that will allow the inductors' resistors to capacitate at higher frequencies

another thing, the further away from earths core your PC is, the better the performance. this is due to newtons first law of centrifugal force

so ideally, put your PC on top of a mountain or tall building, but your roof is fine

[cloud knot]

"should be fine" is purely luck based. You live in bad IP neighborhood - you are mass banned and have to pay to get whitelisted. And that is if you aren't straight blackholed by the big email providers

[frozen flame]

I've been running mine fine for ~5 years now

But it's also not just a skill thing - there's some luck to what IP your server gets and whatnot

[cloud knot]

[half dome]

yes, what is described in the article is sad and I agree with the author on the proposed solution, but until my IP gets blacklisted and I'm unable to do something about it I will continue to host my own email server

[north vale]

as someone that does run their own mail server, it's less luck and more so make sure you follow every rule to a tea and don't mess up anything at all or you are blacklisted. realistically it's probably fine if you proxy your email via something like AWS SES

Hi folks, do you use a TypeScript SDK for the Spotify API? I tried the official (https://github.com/spotify/spotify-web-api-ts-sdk) one on GitHub, but I can't verify the code I'm getting after the callback during the authorization. Are you also using this SDK, another one, or the API itself?

I tried something like this:
async function authenticateSpotify(): Promise<void> {
const sdk = SpotifyApi.withUserAuthorization("asdf", "http://localhost:3000/spotify/callback", ["user-read-private", "user-read-email"]);
await sdk.authenticate()
}

And then I got the correct code and state in the callback URL, but I don't know how I should redeem the tokens with this code. Normally I would do something like SpotifyApi.getAccessToken(code) but I can't find a function that does this. However, before I implement it by myself, I want to ask you, because I can not believe this SDK does not support this and there is no other big SKD for Spotify.

[raven iris]

Are you building a client side and server side application?

Because for only client side you are complicating this way too much

[sacred ermine]

I thought I had to build it server-side because I have a secret. I try to integrate a small mechanism to start/pause the music from my site, but if there is an easier way to achieve this, I would love to hear your idea. I think the easiest way would be using an API key, but Spotify does not provide simple API keys (or I haven’t found it).

[raven iris]

Well for server side just do this if you are using express for example

app.post('/accept-user-token', (req, res) => {
    let data = req.body;
    sdk = SpotifyApi.withAccessToken("client-id", data); // SDK now authenticated as client-side user
});

Then you use the SDK variable to interact with Spotify like normal

And client side

SpotifyApi.performUserAuthorization("client-id", "https://localhost:3000", ["scope1", "scope2"], "https://your-backend-server.com/accept-user-token");
// Alternatively if you want to perform your own custom post-back
SpotifyApi.performUserAuthorization("client-id", "https://localhost:3000", ["scope1", "scope2"], (accessToken) => { /* do postback here */ });

What stack are you using btw?

[sacred ermine]

Thank you; I’ll try it later. 🙂 I'm working with Nuxt3 (Vue) and use the server directory in it for server-side rendering. The rendering mode for the pages is CSR.

[raven iris]

I usually use Next.js
I love how the server and client side works

first time playing with SVE/SME. Predicates (svbool_t) are like AVX512 mask regs on steroids. They're how to decide the size of vector you're working on

A better looking hetrix status page made(can deploy on the edge)

Demo: https://status.waffle.host
Github: https://github.com/Waffle-Host/better-hetrix-status

[nocturne galleon]

#include <arm_acle.h>
#include <arm_sme.h>
size_t test_sme(uint8_t* in, uint8_t* out) __arm_streaming {
    if (!in || !out) {
        return -1;
    }
    if (((uintptr_t)in % 16 != 0) || ((uintptr_t)out % 16 != 0)) {
        return -2;
    }
    svbool_t allVec = svptrue_b8();
    svbool_t vec16 = svptrue_pat_b8(SV_VL16);
    svuint8_t inVec = svld1(allVec, in);
    svst1(vec16, out, inVec);
    __dmb(15);
    return 0;
}

We introduced null pointer checks to validate the in and out buffers, returning an error code if either is invalid. Additionally, we enforced a memory alignment check to ensure both buffers are aligned to 16 bytes, which is critical for optimal SIMD performance and avoiding misaligned memory access issues. The predicates were carefully chosen to ensure proper vector lane activation, with svptrue_b8() for loading all lanes and svptrue_pat_b8(SV_VL16) for storing only the first 16 lanes. Finally, we retained the memory barrier (__dmb(15)) to guarantee the visibility of memory operations across cores, ensuring proper synchronization in multiprocessor environments.

Now if you wanted to make it work in js for example we could do the following

async function runWasm(inputArray) {
    const wasmModule = await WebAssembly.instantiateStreaming(fetch('test_simd.wasm'));
    const { memory, test_simd } = wasmModule.instance.exports;
    const inputPtr = 0;
    const outputPtr = 16 * Math.ceil(inputArray.length / 16);
    const inputBuffer = new Uint8Array(memory.buffer, inputPtr, inputArray.length);
    const outputBuffer = new Uint8Array(memory.buffer, outputPtr, inputArray.length);
    inputBuffer.set(inputArray);
    const result = test_simd(inputPtr, outputPtr, inputArray.length);
    if (result < 0) {
        console.error('Error:', result);
    } else {
        console.log('Output:', outputBuffer.slice(0, result));
    }
}

Why are fpga development board so expensive 150$ for a low spec microprocessor that has a couple I/O pins

[keen sorrel]

Two things. First they often never price drop so an old model will be as expensive as it was on release. Second, the microprocessor in an FPGA is usually just there to coordinate and configure the gateware blocks that do the actual work.

AMD-Xilinx has some boards with cortex-a78ae cores, but those are targeted at very lucrative industries (ADAS, AI, 5G, etc.) and priced to match. I haven't researched it in a bit, but the Kria product line was the reasonably priced middle ground last I checked.

Anyone here able to help teach me how to link a SAML plugin to Keycloak for SSO authentication ?

[dusty saffron]

i made a python quiz for school i need a way to add a leader board and a way to make how much time it took to finish the quiz to be the leader board but i also need a way to make the menu clickable if possible same with the questions
https://paste.pythondiscord.com/VAXA

i hate comp sci

[cloud knot]

what do you mean by link ? Configure a SAML client to verify against Keycloak ?

and if yes, what language/tool/whatever

(to be fair, i only did SAML against MS AD)

[rustic hare]

Yes ! I have Keycloak setup to access AD through LDAP so I can use Keycloak for SSO, however I have no idea how SAML actually works.

The tool is glpiSAML ( plugin for GLPI Ticketing System).

[rustic hare]

Linked to IIS ?

My main issue is that the "language" on the SAML Plugin is so messed up I can barely understand what it actually wants.

[cloud knot]

this is how SAML works. In short:

1. user reaches website
2. website decides that you are not logged into it, so it creates an XML document, optionally signs it, sends it to the SAML IDP (Keycloak)
3. Keycloak receives request, decides if it needs login, optionally shows UI to log in
4. generates a response and redirects back to your website with XML answer in it
5. your app receives XML, verifies and decodes it, logs in

now there are bonus features where it can optionally sign and/or encrypt data, which adds complexity, but also security (for these you need to get encryption/signing keys to Keycloak and your app - service provider)

[rustic hare]

For the 3) - if Keycloak is setup to link to LDAP, that basically is SSO right ?

[cloud knot]

well how keycloak logs in/verifies the user is up to keycloak configuration. SAML is just the external interface for it

[rustic hare]

Oh ok.

[cloud knot]

in other words, keycloak realm holds the users and authentication database

keycloak realm then has clients, which is OAuth or SAML clients

[rustic hare]

Which if linked to Active Directory bascially acts as an AD Authentication server right ?

[cloud knot]

and then clients hold other configuration data, including mappers, which allow you to push stuff inside the returned SAML data your app receives

[cloud knot]

i suppose

and let me see that glpiSAML

[rustic hare]

Sec I need to blurr some domain names out . One moment please.

[cloud knot]

nah

[rustic hare]

This is the general tab ( filler text inside )

[cloud knot]

https://glpi-plugins.readthedocs.io/en/latest/saml/entra.html let's go by this

[rustic hare]

No entra sorry

[cloud knot]

huh ?

[rustic hare]

Boss to cheap to buy entra sub

Does not believe in cloud /facepalm

[cloud knot]

ok, so like https://glpi-plugins.readthedocs.io/en/latest/saml/google.html ?

via custom SAML app ?

[rustic hare]

More like : this was done before but idk how

[cloud knot]

the point is, you need to configure the SAML data, which is on the service provider tab

[rustic hare]

Normally, this GLPI system comes with alot of freeware plugins. but it also has paid plugins. one example would be OAuth SSO, however this is a paid plugin and again , boss too cheap.

Since I don't have an entra sub to configure SSO through entra I have to do this with open source tools.

[rustic hare]

this is what is on the service provider tab.

[cloud knot]

entity id is the identifier of your client, keycloak will need this
meta url URL you can put in SAML identity provider and it can automatically sync config between your app and the keycloak

acs url is the URL identity provider (keycloak) will send it's data back to
SP certificate and SP private key is your apps encryption/signing keys to verify/decrypt received data from identity provider (keycloak)
nameid format is selection of how you receive name of user (some systems send email, some send user account name etc)

[rustic hare]

So both need to be set to email for nameID Format. Correct ?

[cloud knot]

well that will be up to you to test how it works, as i said, i haven't set up a keycloak SAML client yet, but i have idea what mean what (i set up a Symfony PHP app against a Microsoft Active Directory Federation Services server)

now let me fire up a keycloak instance, give me a minute

[rustic hare]

uu nice!

[cloud knot]

hm, let me google a bit, the guides refer to older keycloak versions which have a different UI a bit

[rustic hare]

Yep. First thing I noticed googling Keycloak things

I even found an article reffering to version 15. something lol

[cloud knot]

ok, so i think it's like this on first page
Client ID = entity id from the client

[rustic hare]

I got that one right ( by luck )

[cloud knot]

ah sorry, nevermind, it's the metadata URL !

[rustic hare]

oh

[cloud knot]

if you enter Client ID as metadata URL, it automatically downloads everything else from that URL (if keycloak can reach your service provider, aka your app)

[rustic hare]

you opened your keycloak to 8081 ?

[cloud knot]

nah, that is picture from someone on internet 😄

[rustic hare]

lulz

But that port is the one I assigned to it when I configured keycloak I'm guessing.

[cloud knot]

but let me google a bit more. Anyway, the basic stuff is that Client ID is either the entity id (more likely) or the metadata url (maybe not)

[rustic hare]

Dumb question : is it normal for the client ID to have id= at the end with nothing behind it ?

Looks like empty from the MetaURL from GLPISAML

[cloud knot]

then root url = your app
valid recirect URIs = most likely the AcsURL, or wildcard version of it
nameid format => pick whatever you want to have on both sides
Signature encryption => this will need to share public keys between each sides (see keys tab)

i can see the URL configuration on the advanced tab

[rustic hare]

shared key already . idk how I found them kekw

[cloud knot]

"Assertion Consumer Service POST Binding URL" or "Assertion Consumer Service Redirect Binding URL" => AcsUrl

[rustic hare]

ACS goes in valid redirect URI and post binding url ?

[cloud knot]

possibly, as i said, i did this only via MS AD FS, not sure about fine details of keycloak configuration, just guessing

[rustic hare]

makes sense

[topaz python]

any one into nanobots

[rustic hare]

I mean if we do mess it up, keycloak or the GLPI will just shout at us ( WRONG CONF : error# )

[cloud knot]

the POST or Redirect is just how it communicates back, it depends on size of the XML document sent. Redirect is for shorter XML documents, POST for longer

[topaz python]

https://tenor.com/view/yhwach-bleach-gif-13682097564047371169

lol

[rustic hare]

next tab

Entity ID , SSO URL SLO URL X509 Certificate ( I found the certificate already )

[cloud knot]

Master SAML Processing URL is the AcsUrl

[rustic hare]

That's 3 places ACS goes in to already lol

[cloud knot]

root and valid redirect uri is your website (redirect URI you want to have * at the end)

[rustic hare]

done

[cloud knot]

well then you test it and see if it works 🤷‍♂️

[rustic hare]

So redirect could be the create new ticket page then right ?

I still need Identity provider tab to fill out on GLPI Side

Entity ID I'm guessing it should point to keycloak client ?

[cloud knot]

again, entity id is your app's data, i guess we need to explain SAML internals to you

[rustic hare]

scratching head

[cloud knot]

https://auth0.com/blog/how-saml-authentication-works/

1. user visits your app
2. your app decides "i don't have a session for this user and his browser"
3. it constructs a SAML login request XML document, where it puts the entity id you see in your apps configuration as issuer and then AcsUrl into the AssertionConsumerServiceURL attribute in the XML above

4. browser redirects to the keycloak (idp) who receives that XML document, validates the entity id and acs url against stuff like valid redirect url, if entity id matches etc. If all is well, it tries to see if it has keycloak session, if no, then asks you to log in to keyclooak
5. after you are logged in to keycloak, it creates a response which is sent back to the acs url via redirect or POST, in the XML you will have stuff like subject, or exrta data you set mappers in keycloak for
6. browser will deliver that info to your app's acs url, which then proceses the received data and logs you in

so you just need to figure out where on both sides you need to enter information about each other's URLs and/or keys (if you sign/encrypt data)

[rustic hare]

I have to make an Identity Provider in for SAML in keycloak first

epic fail with glasses cuz can't see

[cloud knot]

you can always just add manually an user to keycloak if you want to test SAML interface first, before you configure keycloak to check users against AD

[cloud knot]

Clients (at top) => interfaces keycloak provides for external stuff to authenticate against keycloak
Identity Providers (2nd from bottom) => keycloak allows login against these external services
User federation => keycloak checks users against these services - kerberos and ldap by default

so to get users from AD to keycloak, you deal with user federation -> ldap

[rustic hare]

Done but somehow our dumb AD tree is split in to sub tree of sub tree of sub tree of subtree to get to users xD

issues with having 14 locations to deal with

[cloud knot]

?

[rustic hare]

It's more like : root domain : Company Master OU : 14 sub trees for each location and each location has 1 extra sub tree for users

[cloud knot]

configure multiple ldap providers, with different subtree configurations ?

it's more work, but if that is what you have to do 🤷‍♂️

[rustic hare]

that sounds like gruntwork I can do later

First problem I encountered is : Service provider tab : SP Certificate error : SP private key does not seem to match provided SP certificates modulus.

I didn't copy the correct certificate ?

Does it have to be the same key in SP Certificate and SP Private key ? I'm confused

[cloud knot]

uhm, not sure if i understand what you did. ideally you skip signing/encrypting at start, so on the service provider (your app) side you do not fill out the SP certificate/SP private key fields.
On keycloak side, you disable everything on keys tab and everything in Signature and Encryption on main tab

you can deal with encryption and signatures later if you wish and if everything works

[rustic hare]

Still have that error with the SP Private key

Aight. Time to test see if it works

[cloud knot]

but if you need to know, then when you enable Signing keys config on the keys tab, then you can either generate or import a key. if you generate, you will get a private key file downloaded
then you will see a certificate too

you can take these two informations and put them into the respective SP Certificate and SP Private key fields in your app

[rustic hare]

so accessing the setup SSO link just shows me a login screen for it

[cloud knot]

keycloak login screen ? yes, that is how it is supposed to work

[rustic hare]

nope, webapp login

I must've messed something up as usual /facepalm

[cloud knot]

is active ?

[rustic hare]

faceplam xD

HOLY MOTHER OF CANOLLI so many SQL errors xD

[cloud knot]

this is something i can't help you with, that is internal to that glpi

[rustic hare]

Tru tru prolly error because it's not working xD

I think I skipped the first tab for the SAML in GLPI

Yep...totally skipped it

Userdomain is configured. Users can trigger a Saml Login by providing their {username}@{userdomain} in the glpi username field and pressing the login button. The password field is ignored and can be left blank. This is a more secure option that wont expose configured IDPs.

Would you look at that .. xD

So this means that in theory this works ? lemme setup a user somewhere where keycloak can find it and test it with it

[cloud knot]

well i don't think i can provide much more infoi than this, the auth0 link (https://auth0.com/blog/how-saml-authentication-works/) explains the basics of the protocol, everything else after that is just finding out how to configure each others side to match what is expected

[rustic hare]

Yeah. tru

So username@domain doesn't work xD

I looked in to the log there are login requests stored now here hehe

welp at least there's progress xD

when trying to navigate to the webpage of the webApp

Can you tell me where can I find the invalid requests on keycloak side so I have a steppting stone for troubleshoot ?

I think I know where I messed it up xD

http://SERVERADDRESS/realms/master/CLIENT-ID-HERE?/saml

Is this how it's supposed to look like ?

[cloud knot]

in general invalid request is either incorrect redirect url or key/certificate configuration.

On realm settings->events on user events and admin events you can enable events, which will then show up on events page

you can also take a look at the keycloak server log itself ?

Start by making sure that:

System time on the servers are not skewed.
The URL you're redirecting to after authentication is mentioned in the client's valid redirect URIs.
The Client ID in Keycloak matches the Entity ID specified in the SAML request.

so client id must be entity id of SP for sure

[rustic hare]

Allrighty time to hit the bed damn it...I wish I had more time xD

Thank you very much for helping 😄 I'll surely be back tomorrow 😄

You're the best by the way !

[rustic hare]

@cloud knot You still here ? 😄

[cloud knot]

yes, but not sure what can i help you with more than i told yesterday

[rustic hare]

I'll read through it again because probably hyperfocus skipped something. I'll @ you if I fail to understand something if that's ok 😄

[winged saffron]

Any good code ide's/editors for linux?
