and azure you need to pay for shit that is "free" on AWS

This is it in a nutshell

[deep bluff]

A lot of apps tell you to turn of IPv6, for ex. Valorant

IPv6 is great and all, its just not really talked about much, whilst IPv4 almost everyone knows what it is

[hollow basalt]

Ok

[spring skiff]

I obviously know it's the smarter and more secure way, but is creating and setting up on my github account a new ssh cert for each device worth the extra effort over just copying my existing one to every device of mine and just using the same one everywhere?

[deep bluff]

Honestly, thats a great question. If each new key is doing the exact same thing, it wouldnt be any different, from just having the same key over and over?

[peak acorn]

I copy my key for each device

I don't understand how mocking system features is supposed to work

say im working in go, and I have a service or data structure or whatever that uses Time.now for various calculations. For testing I would like to control the time that the functions are actually working with

So what seems like is most common is you just change around your data structure to basically hold a "provided time function" and under normal operation of the software you give it the "time.now", and when you test you give it "customTimeFunction(...)" But if you do that aren't all your tested data structures going to get super bloated where everything that needs control is gonna be in every constructor etc etc

Apparently theres this 'monkey' package that can directly override a function within the go instance so that seems to be the best solution for small scale mocking like this single function override

[surreal chasm]

Forward your key with your ssh-agent

(Still working on it, will love to know what you think of it)

@deep bluff

[deep bluff]

? do i know you?

[deep bluff]

It looks like its missing something

[silent gust]

What could it be

[silent gust]

We talked sometimes

[deep bluff]

The left menu bar needs to have atleast 3 more icons, and needs to be less fat. Secondly, the right side of the screen needs something maybe a faded logo

[silent gust]

A type of background?

[deep bluff]

Could be buttons etc. I just say it looks very bland, id do something with that space

[silent gust]

I see

Should i make the button bigger?

Because somewhy reducing that space doesnt work

[inner wraith]

You ask, so I answer.
Putting both sides of the conversation on one side is bad UI and distinguishing them by icon alone isn't great either. Go look at any text messaging software and what they do with chat bubbles.
You're using a lot of space for two buttons with that sidebar unnecessarily. You could put in a narrow top bar or if you'll only have two put them inline with the input box. Ideally you'd make them buttons so you can see the pressable area and labelling them never hurt.
The lack of colour leads to the whole thing looking a tad dull. Not unforgivable but a splash of colour or at least different shades for the send button or to distinguish between sides of the conversation would make a difference.

[silk eagle]

notice how in Discord, theres a gap between messages with someone's display name & the message's timestamp above any message content to differentiate messages/message groups

but the reason discord is able to do that is because the messages take up the entire message section of the window

if youre doing bubbles, youll notice most apps like skype and whatsapp will put the different sides of a conversation on different sides of the message area

and usually have names between the messages above chat bubbles to separate them in group chats

[silent gust]

Yes, i did tried to put them on both side but for somes reasons when i try that there are like somes blanks space between the bottom user label width and the top ai label width

i still work on it and your answer do really help me on it thanks guys!

[silent gust]

is the sidebar looks better?

[inner wraith]

Well it's smaller but still not a good use of space. If you can't live without a sidebar for two icons at least use a bit of it and give them labels and position them relative to the top or bottom.

[silent gust]

i will add them later for sure but i will still love an image example of what you are trying to say

[peak acorn]

Is just putting multiple addresses into the DNS for your website actually how services are load balanced

on the highest level

[midnight wind]

no, not really

[peak acorn]

How do you avoid a single point of failure then?

Theres loadbalancers which my understand is it basically is the first line of defence, you talk to it and then it redirects you to one of the instances of the actual product

but if theres only one load balancer then if that fails arent you screwed?

[midnight wind]

from what I understand you can do that with DNS, but it's not that reliable and good

[midnight wind]

who says there's only 1

you can have multiple

[peak acorn]

How do client's know which load balancer to talk to first?

[midnight wind]

welcome to anycast

that's how 1.1.1.1 is one IP, but all over the world

[peak acorn]

Yeah yknow i never considered that 1.1.1.1 doesnt just have one server lol

[white bear]

recently got into programming and trying to make a discord bot with python changed the token to something random for this i have the error message two andbody know whats wrong?

is there anyone here who knows if there's a way to make this code run faster/optimized

[midnight wind]

you are missing an argument

look at the examples

[white bear]

Alr I’ll check that out

[cyan niche]

Could I interest you in calculus

Oh man they're rectangles even better

[deep bluff]

nein never again

[lone vault]

What?

[silent gust]

in python discord you have to set an intent to use the bot

so for example here is a simple discord bot template you can use

import discord
from discord.ext import commands

intents = discord.Intents.default() # Your error
intents.message_content = True # important to have

bot = commands.Bot(command_prefix='!', intents=intents) # for commands you can choose your prefix

@bot.event
async def on_ready(): # when bot successfuly connects
print(f'Logged in as {bot.user.name} - {bot.user.id}')

@bot.command() # command when used ! ( still have to set the name parameter if i am not wrong to use the hello method)
async def hello(ctx):
await ctx.send('Hello! I am your friendly bot.')

bot.run('YOUR_BOT_TOKEN') # YOU BOT TOKEN GOES HERE

[midnight wind]

You can use calculus to easily solve it if I understand the question correctly

More specifically derivatives

And solving for when the first derivative of the area function is 0

[lone vault]

Oh

[cyan niche]

I thought it involved curves, but no curves means no calculus required

I think I can solve it in O(n)

[kind jacinth]

I think you just do a sliding window and take the max area

[lone vault]

Yup,that’s what I did(?)

[lone vault]

Show me

[peak acorn]

We don't have 40 col terminal editors you can use multi character variable names

[cyan niche]

I was wrong, I'm pretty sure it's NP-hard

See: https://en.wikipedia.org/wiki/Subset_sum_problem

Since this problem is essentially a reduction of the generalized form of this problem, seems like the best you can do is O(n^2)

(that is, exhaustively check every single rectangle)

[next igloo]

I looked up the Intel HD 4000 on TechPowerUP, which is what my laptop uses.
Does this sheet refer to what the Intel HD 4000 supported in 2013 when it came out, since openCL 1.2 was the most recent version at the time. Or is the sheet saying that openCL 1.2 is the latest the hardware/drivers of the HD 4000 supports at all?

[inner wraith]

The latter.

OpenCL 1.2 only for HD4000/2500.

I'm working with Mastodon.py - what's the difference between on_update and on_notification?

[silk eagle]

docs just say:

[fair latch]

But a notification can be a new status and vice-versa

[silk eagle]

so Mastodon.notifications says:

oops highlighted wrong thing

the line above that one, update - ...

not sure if its relevant to on_update though

[fair latch]

Interesting that on_update is separate then.
In addition, when you yourself post, it appears as an update when streaming from the API.

Testing it currently.
Seems if you reblog, it appears as an update with nothing in content
Seems if you post, it appears as an update

Seems if you reblog and the original post is edited, it appears as a notification of the type update

[terse veldt]

I'm starting to learn basic HTML/CSS to build pages on my XenForo site (so I don't really need PHP/JS/etc).

So far I'm using VSCode on my PC. But I wonder, is there an app that's available on Windows and Android (say my tab S7) that would let me work on those pages on-the-go?

I've considered GDrive sync, but doesn't seem like there is any out there really. I've looked and github works on VSCode, but is there any android app IDEs that support github and html5/css3? (Don't need more than those two languages)

[silent gust]

you asking alot

i will consider using github codespace for the task you asking because others app might work but in a tradeoff

[terse veldt]

I don't need hosting, I have that already.

[midnight wind]

easiest would something like github codespaces, it's a cloud based vscode IDE

files are tracked via git and stored in github

there is also a vscode web app now at https://vscode.dev/

https://code.visualstudio.com/blogs/2021/10/20/vscode-dev

[spark temple]

So GitHub is a version control system (VCS) service that allows you to use Git (or Mercurial if you desire). Meaning they host a Git Server and that stores your code. Your local machines will clone, commit, and track changes to that code.

On Windows, you can use VSCode as a means to interact with your Git Repository via plugin or through terminal / bash / shell. You can also use a third party app to interact with your Git Repository too.

Also, with Windows you can load html pages via the browser given the path to the file. This isn't ideal because it won't match how it'll actually be served on the web. You should use a tool that'll allow you to serve files, aka a server. You can use MAMP or some other server and this will allow you to spin up a local HTTP server. This way you can access your web page in a manner more closely how it'll be served on the web.

So on Android, you need to find a tool that'll allow you to clone / checkout your code via Git. You can actually use (almost) any text editor to modify your code. Now, for it to be served up like you do on Windows, you'll need to find a web server like MAMP for it. Not sure of what's available on Android. But you may find an IDE that on Android too but I can't promise that as I don't know that platform as well.

Lastly, as PresentMokey pointed out, you can use VSCode on the web but you can also spin up a VSCode Server. This will allow you to use your Windows machine to run everything and use your Android as a thin client to modify the code.

[terse veldt]

Do I really need to run XAMPP? There's a extension for vscode that basically embeds Edge in the sidebar so I don't need to alt-tab so much. Just save, go to preview and hit f5.

And I'm not doing any JS or PHP. Strictly html/css. My website software, XenForo, handles the user login/registration/etc systems.

[midnight wind]

no

that's just a server hosting software bundle basically

there's a live preview extension for vscode that you don't even need to refresh

[terse veldt]

Yea the built in live preview was giving some odd visuals, one sec

[midnight wind]

as for this, client side JS doesn't matter, you can use it just like html/css

[terse veldt]

this is with ZERO css in the <blockquote>
in vs preview window. browser displays fine

[midnight wind]

click on it with dev tools, and check styling

curious what the issue would be, I never had issues with it

[terse veldt]

shouldn't be happening this is entire CSS:

<style type="text/css">
    p {
        text-align: justify;
    }
    h2,h3,h4,h5,h6 {
        text-align: center;
        text-transform: capitalize;
    }
    #mhlogo {
        width: 125px;
        height: 125px;
        float: left;
        padding-right: 15px;
    }
</style>```

with the VSCode "Edge Preview" it looks perfectly fine

native preview though yea its doing that weird black background on black text. Oh and images show as broken in the vscode preview but fine in browser

my prefs are basically default for VSCode except wordwrap defaults on

[midnight wind]

as for images, that's prob just the way you are referencing them

[terse veldt]

nah im following a udemy tutorial. the images render fine in MS Edge. But in the VSCode preview they don't
same file

[midnight wind]

yes, but still

live server actually runs a server

idk how the extension you are using does it, but it may just be opening the file

how are you referencing images?

[terse veldt]

<img src="https://mesozoichaven.com/img/mh_192.png" alt="Mesozoic Haven Logo 192x" id="mhlogo">

[midnight wind]

ah it's an already hosted image?

[terse veldt]

same with local images in same folder
but external hosted fine

[midnight wind]

that should work fine, idk. If you open console it would probobly tell you

[terse veldt]

i mean i plan to not build full pages, don't need the full doctype since its html embedded in a page that gets rendered out with XenForo, so I just do the style & content

that way there isn't two doctypes etc

this previews the page more properly, but it does involve a Ctrl S, click, F5

[terse veldt]

ok so Live Preview works, sorta. It removes the "Click over -> F5" part of previewing, and it fixes the weird black on black blockquotes https://marketplace.visualstudio.com/items?itemName=ms-vscode.live-server

Still have to hit Ctrl + S, but at least that's a lil faster to preview small changes.

[spark temple]

No, you don’t need it for just doing HTML/CSS. But like I said, linking to resources will be weird due to how they are “served” to the page, aka images, external css, etc.

[spark temple]

So again, this is how the resources are obtained or “served” to the client. Paths for these resources can be relative as long as you have permissions locally to the resource. But you can also use absolute paths too, again if you have permissions to that resource.

Now external resources it should be fine locally but may cause issues if you deploy it to the web or how the Live Preview plugins work under the hood. I believe the live preview may be using a HTTP server and this can cause what’s called CORS (Cross Origin Resource Sharing) issues. The server that you are requesting the image from will look at the origin of the request and see it is not an approved domain to request this resource. This protects both the client and server communicating by ensuring a third party cannot inject their own resources but allows the server/client to get resources from other approved domains.

[jovial garden]

Does this count as development? I've been getting an awkward white space in my HTML page trying to display the structure of an HTML page within <code> and <pre> tags, with <code> being inside of <pre.

[silent gust]

I think its cuz you like making another html page in the site

In code you set doctype again with head and title

Idk if indentation counts tho

[jovial garden]

ok

[kind jacinth]

most ai is created using pytorch or tensorflow, both are open source

[silent gust]

I will consider checking out hugging face # transformers module

[neon oriole]

or the one by metabook is also popular since its release and also opensource

[neon oriole]

i think you should take a look at your code , as you are defenetly doing things that the dom wont do (like nesting <pre> or <code>tags inside p tags) given the following code : wich is somewhat allong the lines what you wrote, what do you expect the actuall resulting code on the dom to be? html <html> <head> <title>title</title> </head> <body> <p> this is a p <pre> this is iside the pretag</pre> <code>this is inside the coded tag</code> this is insde the ptag <pre><code>this is inside the codetag inside a pre tag inside a p tag</code></pre> </p> </body> make a gues... 😄 does your guess look like this: ? ```html
<p>
this is a p
</p>
<pre> this is iside the pretag</pre>
<code>this is inside the coded tag</code>
this is insde the ptag
<pre>
<code>this is inside the codetag inside a pre tag inside a p tag</code>
</pre>
<p></p>

not that you do it but i also wanted to add that you also cant do h1- hx tags inside ptags , if you nest inside any tags , the dom automaticly closes the ptag before opening the tag you wanted to nest

then specifially on the whitespace: well if you indent your sourcecode inside of a pre tag (wich literally means the text inbetween this tag , is preformatted DOM DONT TOUCH THIS!) the indentation wil get printed as is on the html page

[cyan niche]

if the dom wont do it just force it

[neon oriole]

na the nesting is a "feature" of html

you cant nest stuff inside ptags but a verry few things

the dom will automaticly assume you forgot to close the p-tag , and close it for you before the nested tag

you can check the behavior with f12 in the browser , wich shows the actuall html that is being displayed (view sourc only shows the code that got received not what the dom made of it)

[cyan niche]

https://jsfiddle.net/sfp48d1e/4/

[neon oriole]

nah is thast what your dom is showing? , anyways (clip is a rection video by the primagen, original clip is from Computerfile)https://www.youtube.com/watch?v=Gj5Q-x3OrWo

[cyan niche]

https://jsfiddle.net/sfp48d1e/22/

You can force the dom to do what you want with javascript, and it'll even render correctly.

[neon oriole]

jeah javascript (depending) but manipulates the dom after the page is created, so yes and no, the page is frist rendered as i say , and then javascript goes in and changes it

[cyan niche]

your function is indented incorrectly

[neon oriole]

and there is a reason i wont anything js not even from afar

[cyan niche]

lol

Why is it nested under initiateBot()?

Is there a reason I don't know why you're using an inner function

It needs to be exposed globally in your file

inner functions are only accessible under the function they're defined.

i.e., shift + tab everything starting with @client.event and below

The on_ready function is called not by your program, but globally hooked into by Discord's API. it needs to be exposed at the top level. It's not defined like how you think. I recommend looking at some examples of how Discord bots are arranged

python is block scoped - i.e., variables/function defitions don't exist outside of the block they're defined in.

I assume you're new to programming. Good luck!

[hardy ledge]

You don't need public

Also the official Python server has a dedicated channel for Discord bots.

[silk eagle]

do decorators work if they arent directly above a function? I've never tested that

or does it just not care about empty lines between the decorator and a function

[cyan niche]

I imagine the python parser ignores blank lines

[silent gust]

It cant

Indentetation

[silk eagle]

it does

even with the indented empty line it ignores it

[silent gust]

That is alot of function

i totally yoinked that from a geekforgeeks article to save myself the 5 minutes remembering how decorators are made

make them submodules :?

[spiral tulip]

i'm wanting to learn python to make a small game because since I was 8 I've wanted to develop a game, I have some ideas for a product but before those ideas get out of hand i want to begin learning. can i please get some help with the coding language and maybe a tutorial.

[hollow basalt]

https://www.youtube.com/watch?v=LooBEKmOA7E&pp=ygUZdGFsa2luZyB0byBidXJtZXNlIHB5dGhvbg%3D%3D

[spiral tulip]

i was being serious, i want to learn the coding language, not about Burmese pythons!

[hollow basalt]

ok

[inner wraith]

While you can use Python to develop games it's not an ideal choice for game development for performance reasons. Consider Unity or Godot, both have great tooling for beginners and big support communities, on top of C#.

[spiral tulip]

Ok, I've tried unity but I couldn't get past the main menu but I will try it again soon, what coding languages dose it support

[inner wraith]

C#

[spiral tulip]

That it

[spiral tulip]

Eanyways thanks for the ur help, I'm glad someone took me seriously.

[humble mirage]

I wonder how badly LMG would fail the Joel test

[silent gust]

You can still learn somes python to make it easier learning C#

[cyan niche]

They don't publish salaries so that's one strike

[humble mirage]

i mean that's not part of it

1. Do you use source control?
2. Can you make a build in one step?
3. Do you make daily builds?
4. Do you have a bug database?
5. Do you fix bugs before writing new code?
6. Do you have an up-to-date schedule?
7. Do you have a spec?
8. Do programmers have quiet working conditions?
9. Do you use the best tools money can buy?
10. Do you have testers?
11. Do new candidates write code during their interview?
12. Do you do hallway usability testing?

these are like relatively easy to reach minimums for basic software development productivity that a surprising amount of companies fails severely
(Originally from a blog post by Stackoverflow co-fonder Joel Spolsky)

i work at a company that's about 8/12 myself which in the original post is a fail (under 10)

[humble mirage]

truueee

I didn't think my human machine singularity would turn out like this

I'm guessing they're failing on 3, 5, 7, 10, and 12.

small teams usually are

[neon oriole]

11. -> if they want code , they gotta pay 🙂

[humble mirage]

yeah and i'm pushing firm doubt on 9, since apparently getting RAM is really hard at LMG

8 too, since i think they do a bunch of open plan ish stuff for non management

[fair latch]

I tried, but you can't track files inside a submodule without symlinks, right?

I'm just using this for now:
https://github.com/twpayne/chezmoi

[neon oriole]

well it wont be the first company to write out fake vacant programmer spots , only to have the applicants write code for a code project , to pass that code on to their actual programmers who were lagging behind and needed some help but the company was unwilling to hire extra's

[neon oriole]

how do you mean symlinks? submodules are just folders with a git repo inside another git repo? but you explicitly have to add them as a submodule

[cyan niche]

Attach a copyleft license to your code

"Why did you attach a license to your code? Oh whoops, just the default I have my environment configured on my home code."

"Well we need you to remove it."

"Why?"

[fair latch]

Files inside a submodule are not tracked by the parent repo.
So I think the only permanent solution is to symlink the files inside of the submodule to another file in the parent repo.

[fair latch]

Without a license, doesn't the author retain all rights to the code?

[cyan niche]

Technically, yeah.

You would have grounds to sue either way.

[mortal geyser]

I think we fail at 2,3 and 5-12. (some depend on situation/project tho) I don't know if I should laugh or cry tbh.

[humble mirage]

hey, Team Foundation Server and an old home grown ticket system is a start!

(that's what my old job had)

although we also dogfooded heavily which imo fulfills #12 and did have a bit of code in interviews so yeah

[neon oriole]

ah no ofcource but they are tracked by the git repo inside so ... i dont really get whats the issue then i think

ah you want a commit to happen for all repo's and submodules in the tree i assume

you can do that with:```sh
git submodule foreach --recursive <whateve command you like here>

[neon oriole]

depending but mostly yes, the unlicence forgoes those i think , the mit licence (i think the most popular one on github) even requires attribution if you use the code

and on the numbers list, well i dont get these : we fix bugs before we write new code: i think this means the bugfixing happens by the same team, while sometimes good , it means your also using your creatives to do the tedious work much better done by more consenious people, and i would like to see a dedicated we have a documentation team that documents our code and writes manuals (both to use the end product as how to use the code , for other teams within the company, and they should automaticly get any file with a diff in it to update the docs if need be 🙂

[fair latch]

I don't own the submodule's repo, so I can't push to it.

The only way to do it is to remove it from cache and explicitly git add submodule/file before pushing. That makes the file appear in the root of the parent repo without the submodule.

[boreal crystal]

Dont really know where to ask but are there any command line malware checkers?

[cyan niche]

Good for you for saying how you solved it

[drowsy elbow]

Anyone knows how to fix this? I already rebooted my phone twice, rebooted my pc, rebooted my router & disabled and re-enabled developer mode on my phone twice

It was working just fine yesterday

I also downgraded visual studio to previous version to see if it did anything

Managed to fix it by using adb pair this time. Idk why connect didnt work

[red mulch]

nobody else is going to give a shit

but

many days of work for... that 😉

[drowsy elbow]

What does it do?

[red mulch]

it's an abstraction of pipewire - which is for audio routing

so it has actual devices, like an audio interface. I'm abstracting that out to an actual THING, like a microphone. And then making it so you can 'jam' that microphone into whatever

of course, there was no decent pipewire python lib, so I had to write that first.

[silent gust]

Waw

[red mulch]

It's all kind of stemmed from https://github.com/hrdwrbob/surfacepresser this

I went to write some code that I could easily use to configure my midi surface to do stuff I wanted to do, and when I found that it didn't really exist, I kinda rabbit holed it

because while what I've done there is pretty good, it's really no use to anyone who doesn't want to bash out yaml. and shit. I don't even want to bash out yaml.

[drowsy elbow]

What problem does it solve?

capture midi device input?

[red mulch]

as per the code above on github, it just provides the ability to manage pipewire and some other stuff with a midi contoller

the new stuff I'm working on solves the problem of managing complex audio routing in a simple way, and dynamically adjusts controls to suit.

I am using my server as an audio router - I have 5.1 surround from a chromecast, and 5.1 from my desktop going in, mic out to desktop, in/out from laptop, in from actual mic, in/out to phone, out to speakers, out to wireless headphones, out to wired heaphones, out to outdoor speakers.

[inland jay]

interesting project... ive been meaning to set something similar years ago when I had audio from multiple PCs I wanted to control from a midi device... never got around to it and don't need it now but cool to see someone work on it.

[lapis hearth]

does anyone know how to use a digispark

[red mulch]

honestly prior to the existence of pipewire it would have been super jank. pipewire being the backend and abstracting away all the hard bits of audio routing means I can focus on the abstraction from 'port' and 'device' and 'link' to 'thing connected to thing' for people

[red mulch]

did you plug it in? 😛

[lapis hearth]

i got it to work

[red mulch]

cool, what was wrong?

[lapis hearth]

i was being a dumbass

What emulator should I use to test Linux software on Windows 10?
I have a program that uses OpenCL for GPU compute, along with SDL2

[spark temple]

Why use an emulator? Just spin up a docker container with Linux.

[red mulch]

uhhhhh emulate? what? windows comes with WSL. but it really depends what you're doing

[silent gust]

Virtual machines?

[silent gust]

Sus

[random bison]

I have an unusual one...
Has anyone used Yahoo APIs to integrate with Slack for the purposes of Fantasy Football?

[crisp bronze]

Does your software has a GUI? VirtualBox is the simplest for beginners on windows IMO (its also free).

If your software is cli only, use docker. It's much faster and smaller than using virtual machines.

[next igloo]

I do have virtual box, but I was a bit concerned that its graphics emulator might not work for OpenCL 1.2. Yes my software does have a GUI

When I tried to run it, it failed to open because I was missing some library files since it was on a fresh installation (not virtual boxes fault). I am yet to correct that currently

[crisp bronze]

Yeah, thats the joy of emulation for you xD

If you have a spair computer laying around it will be best to install linux on it and access it remotely. With ssh for terminal access and scp to transfer files you can automate the whole thing 🙂

If your windows version and hardware supports it, you can also try hyperV. I had good results with it (circa 201). Better performance, closer to the metal and free (comes with windows pro).

It wasn't as easy to dev with tho (never got file sharing to work and I never saw how to controlling it with cli). But its probably better now 🤷

[crisp bronze]

When I tried to run it, it failed to open because I was missing some library files since it was on a fresh installation (not virtual boxes fault). I am yet to correct that currently

Oh I thought you meant the windows install was fresh

[steady wren]

What Fullstack Enterprise framework do you guys recommend that is FAST AF, scalable, and easy to maintain?

[midnight wind]

what are your requirments

and preferences

[steady wren]

Must be

• Fast
• Scalable
• Easy to maintain/develop

Must be capable of

• Handlng 200k+ queries/hour
• Must be able to take a JSON body in the request, and pass it to a script (Some type of script that has some sort of testing library)
• Must be able to dynamically load the scripts in one folder. Meaning I can add a script to the folder without reloading/recompiling/restarting the backend app

Preferences

• Auto Garbage collection (Don't like having to allocate and deallocate memory like C++)
• Good documention
• Able to easily integrate the Frontend into the fullstack app

[midnight wind]

you are asking a lot, alot of that depends on your overall architecture, deployment, and development not just the framework itself. You can use phoenix, django, Ruby on rails, asp.net, and a lot more. There also also products like supabase which handle the backend which may be a good option, depending again on your product and what it does

[steady wren]

Alright. Wouldn't django be slow since it is python?

[midnight wind]

not necessarily, instagram is built on top of django

again depends on well you can use the tech

https://instagram-engineering.com/web-service-efficiency-at-instagram-with-python-4976d078e366

[steady wren]

I just am worried about the latency from the request from the frontend askign the backend to test this user's code which the backend routes the JSON body to the script, and the backend returns the response from the script

Frontend -> backend -> testing script -> backend -> frontend

[midnight wind]

so you are running user code

I wouldn't be worried about latency, that's not the issue here, it will be most likely negligable

[steady wren]

I also forgot to think of we are going to test the different programming languages that we are going to offer. Oh, this is complicated

[midnight wind]

what are you trying to build? a code sandbox?

[steady wren]

Online learning platform

[midnight wind]

ah

[steady wren]

I try not to share details much

[midnight wind]

if you are running user code on backend you need to be really careful

[steady wren]

Yes. That too

So I've been trying to work with materialize since for me, its very easy to understand and tweak (since you can literally do something like nav class="blue darken-4" to change navigation, similar with footer). But for some reason, the materialize CDN I use doesn't seem to work for a mobile view? It adds the "hamburger menu" but it renders the rest of the page like desktop. Not sure what's going on.

I'm using the cloudflare lib for it, v 0.100.2.

[red mulch]

diagrams are fun

[red mulch]

if your thinking is "python is slow" - it really means you don't know enough to decide 🙂 - not that python is super fast, or blah blah blah, but the realitt is that for most things, most of the time, premature optimising - including choosing "fast" underlying tech - is a terrible idea.

[steady wren]

I don't use Python much sooo

I also converted my Java TicTacToe with recursive minimax algorithm into Python, took 4 seconds to respond. So that's my experience

[red mulch]

haha, ok - that depends on so many different things. I mean, python, less than java, but more than some others, has a startup penalty of a few hundred ms, but that (like java) is irrelevant once the python interpreter is loaded

it also depends on what you're doing - if you were doing a pure python implementation of a heavy algorithm? yeah it might be significantly slower. But that's not what 99.9999% of python is doing.

[red mulch]

all the bits in this, more or less, can be swapped out for different tech, but it's pretty much a reference pattern. The workers also may or may not update the database or other stuff, but it doesn't really change the components you need.

[humble mirage]

python is 4~16 times slower than languages whose reference implementations support multithreading

but that apparently may change, I heard

[hollow basalt]

how? Removing the GIL would break not just python but several projects that also relies on the GIL

though relying on GIL for safety might not be a good practice but who am i to tell

[kind jacinth]

https://peps.python.org/pep-0703/

[deep bluff]

You can already bypass the GIL iirc

[hollow basalt]

Ok

[white bear]

this might sounds stupid but is something like start = false a variable or is it if start is not

python btw

[frozen flame]

GIL will be gone soon

Anyways python has gotten significantly faster in recent releases thanks to a lot of underlying changes in cpython, but most web workers work around the biggest issue (namely the GIL) by using worker processes instead

[frozen flame]

Yes that's a variable

Also if you're going to sandbox user python code take a look at snekbox @steady wren

[steady wren]

Thanks

It will also be other languages

[frozen flame]

Snekbox is a python interface for NSjail, so you can probably learn a bit about using that for other languages from it

[red mulch]

.... What? That doesn't mean anything. Slower at what. Under what situation? As others said, real world usage uses workers etc. "X is slow if you run it in a deliberately slow way". Yeah... Ok.

[red mulch]

= is the assignment operator. == is a comparison operator.

[neon oriole]

anybody ever had this with using gdbgui?

[nocturne galleon]

so i have a test and these are the problems im a noob so cant do much

problem 1
In an animal shelter, there are a certain number of cats that eat a different amount of food per day. Your task is to calculate the number of cats in each group and the money the owner needs for their food for one day, if 1 kg of food = 12.45 BGN.
• If the cat eats from 100 (inclusive) to 200 grams, then it falls into group 1: small cats.
• If the cat eats from 200 (inclusive) to 300 grams, then it falls into group 2: large cats.
• If the cat eats from 300 (inclusive) to 400 grams, then it falls into group 3: huge cats.
Login:
• In the first row - the number of cats - an integer in the interval [1..100]
• On each subsequent line for each cat - X grams of food - a real number in the interval [100.00..400.00]
Output:
The following lines are printed:
"Group 1: {the number of cats in group 1: small cats} cats."
"Group 2: {number of cats in group 2: big cats} cats."
"Group 3: {number of cats in group 3: huge cats} cats."
"Price for food per day: {price for food} lv."

problem 2
A group of enthusiasts travel to various locations where there are gold mines. Your task is to help them by writing a program that accepts the number of locations and the expected average gold yield per day for a location. For each day you will receive how much gold they mined at the location. Check whether they have achieved the expected yield for a given location or not.
Login:
Initially, a single number is read from the console - number of locations - an integer in the interval [1.. 100]
For each location, two numbers are read, one per line:

1. On the first line - expected average yield per day of gold - a real number in the interval [0.00.. 10000.00]
2. On the second line - number of days in which the given location will be mined - an integer in the interval [1.. 30]
   One number is read for each day:
   • Gold mined for the day - real number in the interval [0.00.. 1000.00]
   Output:
   After mining a location is complete, one line is printed as appropriate:
   • If the average gold yield per day reaches or exceeds the expected average gold yield per day:
   o "Good job! Average gold per day: {average gold per day for the given location}."
   • If the average gold yield per day is below the expected average gold yield per day:
   o "You need {gold that has not reached the expected average yield} gold."
   Format the result to the second character after the decimal separator.

the first picture is problem 1 and the second problem 2

[humble mirage]

it was a bit of a joke about how many cores cpus currently have that python can not use in a simple way due to its GIL (which is also apparently going to be optional soon which is exciting news and actually intended to be the main message)
no idea why you're so hurt by this? It's a fact that with something like C# where you can just use parallelism in Linq or even just Task.StartNew or hell even new Thread, it is a lot easier and faster (for the developer) to just parallelize parts when the need arises. You can't just do that in a small single file program in Python.

Of course you can do the whole microservice and sharding dance to your application, but that's kind of a different thing

[red mulch]

a lot of people say that sort of thing unironically as if it's relevant generally,.

also.. you can. It depends entirely on what you're doing. If you're using python for heavy multi threaded tasks, you've already done it wrong.

If you need multi threading in your single small program in python, wtf are you doing

[red mulch]

(noting that you CAN thread python and/or use asynchronous patterns, you just don't get any performance benefit)

[lilac sphinx]

im trying to build a song recommendation using spotify in python and although i gave a correct spotify client id and client secret it is showing a key error. does anyone know what is the problem and how i can fix it?

[midnight wind]

don't you need to do oauth

just id and secret isn't enough

[lilac sphinx]

could you pls elaborate?

[midnight wind]

https://spotipy.readthedocs.io/en/2.22.1/#authorization-code-flow

you need to do the first flow in order to access user information

which requires the user to allow your app access via oauth

[lilac sphinx]

oh

i got some idea now
i shall try and get back to you!

[midnight wind]

oauth is a bit hard to understand at first

[lilac sphinx]

for sure
im new to this and it is pretty confusing

[lilac sphinx]

it worked!
but not because oauth was missing but rather i changed the syntax of the line a bit and it didnt show that error anymore

anyhow, thanks for looking out

[silk eagle]

keyerror, usually, means you just dont have that item in the dictionary its trying to grab it from

[red mulch]

It took me a while to get SAML, but now I can fluently speak SAML. It make sense, but I still love/hate it 😄

but... reading the context it's just client oauth. it's a minuor pain, but eh

[steady wren]

Would it be much of a performance hit if I use MariaDB instead of Redist to store sessions?

[midnight wind]

those are 2 seperate types of databases

redist is in memory, while mariadb is actual storage

[steady wren]

Yea, ik. So I assume yes

[midnight wind]

I don't have much knowledege on this type of architecture, but I'd assume it shouldn't be bad, although iirc it's easier to scale Redist then mariadb.

[steady wren]

Alright

[wind horizon]

Yeah it’s very common to see sessions in a DB for small to medium apps, it’s not much of a worry and in one case I even saw on a pretty heavily used app (200k+ users).

I’d suggest going with something from a framework, it’ll have pre-made patterns likely for storing sessions.

If you use a single node / instance of your server and minimal users right now another cheap option is simple in memory list of sessions. But this won’t scale to multiple instances, uses some RAM, and means all sessions or lost on restart so no mid day deploys.

[hollow basalt]

ok

[white bear]

kinda late responding to this but there are a few errors now

[hollow basalt]

For sure

[silent gust]

A~

[frozen flame]

so no mid day deploys.

do it

[silent gust]

Is go language interesting?

[red mulch]

the better question is, what are you trying to achieve? does the performance realistically matter?

[inner wraith]

Totally depends on your load and code, if you're hitting MariaDB on every query already it's probably a bit moot, and you can optimise smallish key-value stores to be really fast. But Redis exists for a reason.

I personally am using Postgres for the lot and if session storage ends up mattering for performance I'll care at that time and no sooner.

The database is much faster than my workers and the workers are much faster than my anticipated needs.

I've been in environments doing that with MySQL for location data with... maybe tens of queries/second all day every day? And the database was as good as idling, our problems were with the backend being slow. That kind of query load basically doesn't matter.

I don't think Facebook or Uber'll be taking that approach but it worked alright there.

[steady wren]

Yes, but I can't say much about the project

[white bear]

?

[inner wraith]

lol if it's Minecraft hosting-related you would be the third I've seen here to have a top-secret project that was actually such

[midnight wind]

it's a code learning platform

.

[inner wraith]

Guess it's still 2 then ¯_(ツ)_/¯

[midnight wind]

user submit code -> code gets run/validated

so need basics of user auth, etc.

[inner wraith]

Doesn't mean much, still completely dependent on implementation.

[midnight wind]

well yeah

[inner wraith]

If it's so secret that scale to an order of magnitude can't be disclosed than asking infra planning and design questions here will give consistently useless answers

[kind jacinth]

Imo trying keeping project ideas secret is fairly naive, considering that thousands of people probably have come up with that idea already but just couldn't find anyone to code it + market it

You just end up obstructing help, while otoh explaining your idea is more likely to get people excited to help

That's assuming you're not just under NDA

[inner wraith]

If you're under NDA pay a consultant to help you lol

Which means fine but every single thing you say into it is collected and analyzed by Google. Chat messages are one of the best things to send to them amirite

[lunar quail]

Yes. 👍

[silver furnace]

What's funny is for a while I've been thinking about stuff like that. For instance, what about direct connection peer-peer chat app? I was looking into peer-peer networks without centralization

So the goal is to connect to somebody you know no matter which network they're on. If it is centralized, maybe everybody id's as secret only the other contact knows. You can request an ip from centralized service by some identifier but centralized service has no clue who that is. Every single time it changes. Honestly lol i got it I think

[silver furnace]

More than that you're I guess sending people's voice recording tied to personal messages + helping train it to understand speech (so it can one day maybe decide it's time for judgement day ala Terminator 3).

[kind jacinth]

Uhhh sure

Something something singularity

[silver furnace]

Irl jokes aside I don't think I know of a single chat app that does that lmfao... and that kind of crap happens to be some of my worst nightmares too honestly

[silver furnace]

Singularities don't exist usually whenever that word comes up in physics. For AI, idk. Is there such a thing even in Terminator? A singular moment when machines become sentient. Is that the very first machine or something? Or is it that when machines became sentient, they were immediately one consciousness somehow which is the very same one that became aware and turned on humans? So many questions...

[silver furnace]

Well jokes aside, definitely shouldnt brush off with sure. The whole thing today with chat apps is they have to be secure and private. Nobody can listen in on conversation except the two people on either ends to whom the conversation actually pertains. Why should a single other place receive people's personal messages lol.

See if you can write a message app but it's end to end encrypted and somehow anonymous maybe to even yourself the dev/service provider. Then at that point honestly it would matter way less again if Google gets every message. Nobody knows who that contact is apart from usual ip, rough location, etc if it's the client using Google api and then sending message afterwards. So if VPN then you can hide identity (thats the whole point)

[silver furnace]

Btw try to fully think through what that 'everything' is. You've sent them way too much for what most people consider acceptable... to Google of all things

Minimally you'd definitely need a privacy policy and agreement to use your app which links to the same of Google. I'd hope you at least make your own service and API that uses Google and just passes along the text response from voice clip. But now you're pretty hefty on traffic. Voice clips downloaded then uploaded as well. Would need scaling if you have a lot of users. Yeah just food for thought. Peace.

[kind jacinth]

It was a for a school project and I no longer give a fuck about it

[silver furnace]

JS experience isn't really important. It's just being able to write on a certain scripting language. There's nothing to JS except for just basically object notation, knowing to write elsif/elseif/else if/elif/elf whatever because everybody has their own way to do it for some fkn reason. JQuery is I guess yeah you'd better use at least that if you're going raw on DOM frontend.

Today JS is mostly accepted in conjunction with other langs/frameworks if you don't type a single line yourself and it's all generated for you. If you write in JS, it better be node or something. Node experience counts.

[kind jacinth]

Also I'm well aware. I run graphene OS, I self host librephotos, I use sync thing as a replacement for GDrive, I use proton mail, etc

[silver furnace]

You can't have Google Play frameworks running on phone at all ideally. Or at least not use real identity in accounts added to it... if any

[kind jacinth]

I mean yeah but there's a spectrum of privacy vs convenience

[silver furnace]

Graphene os yeah Louis Rossmann uses it pretty sure so it can't be bad lol. I heard good things about it privacy-wise. But still unless you're gapps-less and only like fdroid is installed lol... I don't even see a point

[silver furnace]

Right. That's the whole gotcha. It's some of the worst examples with Google. Everyone just uses it too much idk

Although I see nothing wrong with like using them for search engine if you're behind VPN or something. If your identity is anonymous. So browser data cleared too, etc. In that case, Google probably still best for searches lol (unless youre of the opinion that what you're searching for is tampered with). Like it sucks: they have probably still by far best search results but they seem to ruin themselves. Would have been best search engine lol

[kind jacinth]

Well Google search is miles ahead of any other alternative

[kind jacinth]

You should look into how graphene works...this is easily refutable.

[silver furnace]

At the end of the day, it ultimately won't ever not have a toll on privacy so long as you got a 24/7 internet connected brick with a sim card. Sim card you have unique phone number on which you got from provider who knows your first/last, address, etc lol

[kind jacinth]

Yeah if you really care about privacy, you should just be your own T1 ISP. Otherwise there's no point /s

[silver furnace]

I think they actually proved it too. Smart phones that dont have a way to remove battery will still connect to towers even 'off'. Unless you drain battery enough idk

[silver furnace]

Nah perhaps real problem is carrying device on person every second of every day wherever you go. And connecting to anything with it :P

Unless idk what about airplane mode all radios off incl bluetooth and gps? That should work tbh. If it does, wow 2023: your phone is connected least while it's on not off :P

I mean the packet data and cell seem to stop working. You shouldn't have any way to receive whatever it is that could cue your device to re-enable any comms

GSM I think has to be off even with no sim card right? You still connect to cell service and show IMEI? Emergency calls only.

[kind jacinth]

I think you should really check out graphene os

[silver furnace]

You can get throttled if you're not Elon Musk or Google n sht? Also your own ISP lol. So if you have your own IP block? Isn't that worse? Now it's registered on like ARIN or some sht to you.

[kind jacinth]

It addresses everh concern you've had

[kind jacinth]

Bro did you miss the /s

[silver furnace]

Lol true. But all jokes aside, that's kinda a real issue now. Ideally you would be able to start your own ISP for max muh freedoms. But idk how neutral the net is. I heard Google themselves literally throttled some social thing that tried. Parlour I think it was

Emails I said on here before that it's even difficult to host your own SMTP. It's a reverse effect of everybody using like just 3 services literally across entire planet. They will always be permitted regardless amongst eachother. Meanwhile small personal SMTP server you like have to ask for unban every different provider. It's far more convenient like you said to use GMail or something... but probably better just say the only one convenient enough to the point of being guaranteed usable... at all...

So we're at the point where literally people have to ditch some of these companies together as entire internet lol. Just like a revolution for independence but entire planet. And it's net independence in the form of net neutrality. Internet already globalist society minus China and places like Russia a bit now.

[silver furnace]

But the whole thing is can you think of any decent solution that isn't /s and will work. For things like mailbox, I actually challenge you to think of how many different providers the entire Earth uses. I'm amazed that it's actually just a handful. Then you have smaller ones on diff scales I guess specific to countries idk. Those are better and worse in their own ways. It's actually kind of sad.

Like Russia right now: they sometimes ban all of FB nation-wide. China... Net neutrality lol it's doomed from the start. So long as somebody else provides connection, it's threatned. But 1 of 8 billion using GMail idk. That's just asking for it. Maybe VPN is best thing we'll have.

And btw I have an uncle who literally did that. Really polar siberian town in Russia. Has no internet. He was overseeing pretty much operation to set up first ever connection. I forget if it was the second one after satellite or the satellite one itself. I mean he said it was nice. They 'accidentally' pulled like 150Gbps or some sht with torrent client

[wind horizon]

There are a lot of guides from archive utilities to using jar cli. I’d suggest Googling how to extract jar file and then returning to ask for help with a specific step if you get stuck. 🙂

[silver furnace]

Nah there's one that runs on Java. Install Java and get jd. It's click to run jar and select jars to decompile. Idk but you get a lot of it back unless it's obfuscated. If it's obfuscated you still got Java code that's compileable technically. You can edit the Java and compile it still.

Or you decompile like scala to Java. Obfuscated?

[silver furnace]

Java decompiler itself has both

[nocturne galleon]

As I am completely new and have this confusion. As I have scared that which pathway to start with, I am interested in being full-stack engineer as its most demanding and pays off more if I am right?

Which is the right way to progress?
Learn Front-end then after complete move to Back-end then after complete you are a full stack or learn more later on
OR
Just start learning Full-Stack

So does it means that I have to go like this? Front-end then to back-end and finally to full-stack instead of directly starting with full-stack?

So thought maybe I have to complete one by one like front-end then back-end and then full-stack instead of just start full-stack??

Kindly guys give you advice and suggestion regarding this please!

[wind horizon]

You’ll typically pickup the skills for the other over time, don’t worry about “full stack” and just focus on what you enjoy. You’ll do best if your working on something you enjoy working on.

Take the shortest path to full time employment imo, you’ll learn massive amounts on the job and from more Sr engineers once you start doing it 40hrs a week.

[nocturne galleon]

Thanks for answering me, actualy as I am new I don't know which one I will enjoy or not.

I heard a lots doing Web Development/ Web Design by being a front-end or back-end or full-stack or mern-stack developer.

So I want to exactly start the most demanding and future-proof career by which i can work at anywhere and get top paid as well

[wind horizon]

There isn’t much future proofing in this career, you either keep learning and changing or you become outdated. 😅

Just jump in head first, you’ll quickly learn what you do / don’t like. There is massive amounts to learn and do in this field, there is tones of people who never even touch the web. 🙂

If you know you want to be in the web space and think you want full stack, I’d suggest just jump into JS to start. It’s heavily used front end and now popular on backends too, so it’ll give you a decent coverage on both sides in 1 language to start. But keep in mind many of the challenges are different between the 2 areas still.

Often times today devs who do front end are just expected to understand or be able to touch backend. I think the idea of full stack isn’t as much of a special thing as it used to be, now it feels more like “what are you strong in” but working both is average / business as usual.

Many new devs I work with come in knowing only FE and within a year are semi comfortable opening backend PRs. It’s not that they are backend pros and they may still prefer front end, but it’s inefficient often times to have someone only do 1 thing instead of them being able to deliver a full feature including backend work.

But there are positions that are still exclusive, so if you love one and hate the others you can find those roles. We have teams that only build client side code / reusable modules and we have teams that only build internal services and never touch the web app. But I’d just say it’s no longer special imo for a JS/FE dev to be listed as full stack. 🙂

[nocturne galleon]

Alright, thank you so much for explaining me in-depth details

I will got as short form to ask, if I were to select from front-end or back-end or full-stack which one to choose?

[wind horizon]

I’d just start learning to program, you will have a lot to learn for the basics if you aren’t yet programming before you even have to worry about that. 🙂

If your asking because of picking some kind of training / course selection I’d personally pickup one marketed as full stack just so it gets you exposure to a little of each to understand the whole picture.

But you may even end up hating programming, so I wouldn’t over think this. Jump in learn some basics and then pick your path after you have basics of programming down.

[nocturne galleon]

It is choosen that I won't hate programming because I already set up my mind to be a software engineer

So I want to get a full work done and be all in one, so that is why I want to be full-stack engineer.

Thus for that I am choosing code academy, full-stack engineer course to get pro certificate and be a certified

[wind horizon]

You won’t know until you do it, I actually thought I didn’t want to be a programmer growing up. Hated what I went to college for and fell in love with programming. 🙂

[nocturne galleon]

I completed my IGCSE O Levels (Class 10) in 2019, was doing my IAL A Levels (Class 11 and 12), there I had ICT and I did some basics of HTML and Python

But due to covid-19, till now its almost 5 years I am not able to complete my A Levels (College) due to financial issues, so that is why I am seeing maximum persons doing Remote jobs or Freelancing so I that is why wanna enter the Web Development world. So that is why i was asking if the front or back or full is the go green or not! 🙂

[cyan niche]

Be full stack and do both

You can do either

Although any programmer should be able to learn any role.

[kind jacinth]

In my experience full stack is still mainly back end but you're expected to touch some front end every once in a while

Honestly I wouldn't worry too much about what to focus on, your core skill as a SWE is to read documentation. You should be able to self teach yourself any stack with just a few weeks of reading

When you're starting out, it's more important to find a slice you enjoy so you don't lose motivation

[drowsy elbow]

Erm.... this is definetely not null...

I guess the getters throw

[cyan niche]

[silver furnace]

Wow 4-5 days 😆

OTP or nonce usually expires in 5 min max

[silver furnace]

Wow I went on a rant weeks ago about this and people made fun of me. And yet I was right. The lefthand side is essentially originating from *nix username and RH side is just.... 'hostname'. Only it was made before even DNS resolution was written about by Robert Heinlein.

And I was literally on about the issues with the local side of the addys. Basically no standard. It's an FFA match

(Even though there is a standard)

[stone warren]

How am I able to add golang to Notepad++?

[mental panther]

people still use notepad++?

[neon oriole]

yes i do ...

[frozen flame]

Consider using literally anything else tbh... vscode is nice if you don't want a full on ide

Psure there's a golang plug-in for it too

[neon oriole]

to be a complete nitpicker here but username@ip also works fine ,but since according to the talk ('what would become dns?')-lookups were basicly lookups in /etc/hosts -> but not that while unix usernames are always nocaps smpt supports caps , and other non compliant symbols for unix usernames,even spaces in the name are valid

[neon oriole]

i use nvim, notepad++, sublime , kdevelop, ... and i'll resort to programming using paint and an ocr before i ever touch vscode (again), used vscode for maybe 1 day and hated it with a passion nearly everything about it , and take in mind that i had no real problems using visual studio for programming visual basic ages ago ... vscode is just ... a really realy bad editor imho

[frozen flame]

Idk mate the rest of the world disagrees with you

Vsc isn't even my main editor (I use intellij mostly) but I can still recognize how insanely configurable it is through the use of both config files and plugins

[neon oriole]

the rest of the world also tought getting untested covid vaccines was a good idea ,and using spaces for indents is a good idea, so excuse me to not hold the rest of the world to a high standard when it comes to their choices,

[frozen flame]

Oh cool we got an antivaxxer

[neon oriole]

ah no im vaccinated for nearly everything but covid

if someone could give me why a basicly hermit programmer aged 35 who got infected and defeated covid before any vaccin was availeble , would need the vaccin im all ears. but it speaks for it self that you went with the vaccin part and not the spaces part of my reply

funny enough the FDA approved ivermectine as a valid medication for threating covid 3 weeks ago

[frozen flame]

one of those arguments is worth having, the other makes it not worth it to converse at all

[neon oriole]

smells like someone was not telling the truth about it being horsedewormer for 3 years

also smella allot like a money grab as if they would have approved it 3years early , no vaccin could have gotten the emergency use authorisation

on the vscode thing, the last thing i tried to do before i gave up on the editor. is to set the font to: Fira Code : Retina , with ligatures enabled...

and on the plugins part, plugins have become so convoluted that there are now multiple plugin packs (availeble as plugins) for just programming python... and its anyones guess wich plugins are any good , will be maintained into the future, are incompatible with eachother eg...

[fading osprey]

covid vaccines were tested though?

but this isnt the channel for that debate

[neon oriole]

minimally ... not in a way the other vaccines were, and the boosters were untested , unless you count 9 mice as a valid repr for humans

[silent gust]

I will not call something clean and helpful bad

[neon oriole]

define clean and helpfull and we can come to an agreement 🙂

[silent gust]

This aint a clean ui

[neon oriole]

does it have a cli , or terminal version that runs without the need for a GUI/graphical server being present

[silent gust]

Yes

I mean vscode is just good nothing to hate it aside of performance may be

[neon oriole]

vscode has a terminal client , lol well it has a cli, that wraps some git functions, meaning tey made some stuff accessible from commandline but not the editor part , of an editor ... i mean , git already has a cli no need for vscode to wrap it again

[silent gust]

Anyways that not the point it already makes life easier

[neon oriole]

and im happyto offer up some performance for a verry well integrated IDE with its tools, i use to love aptana3 ,ERIC7 (python), and i still use kdevelop for c so

the editor part of kdevelop is also availeble as kate the text editor , unfortunatly also no tui ... 😦

[silent gust]

i understand half or your message lol

[neon oriole]

so vscode is basicly the editor of visual studio but with the development environment dropped from it , and then patched on again with questionable plugins ?

[silent gust]

Plugins are there to help it being customizable

And diversified

[neon oriole]

visual studio also has plugins and is (in terms of MS bound env) quite versatile , ...

[silent gust]

I prefer something cleaner from my point of view

[neon oriole]

and i have no prolems with plugins , and i have the same problem with the plugin system for nvim, ... towards beginners or learning a new language, Wich plugins does one need and or install , that are somewhat maintained . wich ones are required for a basic env and wich optional ,...

sublime text is cleaner then vscode

[silent gust]

Paid tho

[neon oriole]

click a button once and a while like everybody does

gvim ,neovim-qt both are free and much cleaner then vscode (even onivim is cleaner then vscode but written in javascript so :((()

[silent gust]

Its made by windows 🗿

[silent gust]

Why ppl wanna use golang in notepad++

[frozen flame]

I've noticed that whenever many people come by asking for garbage it's because of a YouTube tutorial lol

[graceful drift]

lol fr i tell most my friends to LOOK at the date it was posted it might not be updated

[frozen flame]

Tell your friends not to watch YouTube tutorials for programming lol

[graceful drift]

no i mean like general coding like python, node js and other application set up and so

[frozen flame]

Programming isn't something you learn passively

Ah

[graceful drift]

@frozen flame what do you see when you got to this link https://rapter.ddns.net/info

[frozen flame]

500 error

I don't do php so I'm not much help to you unfortunately

[midnight wind]

that's an error on your end

[graceful drift]

i know i coded the error pages bruh

[midnight wind]

what are you trying to do

[graceful drift]

install php 8.1 to nginx

im checking the logs theres nothing

[midnight wind]

apt install php8.1 php8.1-fpm

[graceful drift]

i might just uses nodejs

[midnight wind]

fastcgi_pass unix:/run/php/php8.1-fpm.sock;

[graceful drift]

i know

[midnight wind]

then it's setup

[graceful drift]

idk where the error is coming from maybe its from the php code itself

no its not from the code

[midnight wind]

get rid of everything before echo

[graceful drift]

i know i just put that incase

did it with out it already

maybe permissions

[midnight wind]

@graceful drift systemctl status php8.1-fpm.service

[midnight wind]

idk then, I havn't messed with php setup in a while. I host everything in a manged enviroment like siteground

[graceful drift]

ill try reinstalling it

[silent gust]

I see vscode as universal

[graceful drift]

wait when i alt tab i see a not full windows with team viewer

bruh

[midnight wind]

1. using teamviewer....

[graceful drift]

i used it a few days ago

was for a quick diagnostic

[frozen flame]

T-teamviewer?

[graceful drift]

it was all he had installed on his pc and i just used it in my browser tho

[neon oriole]

i would love for all the youtube videos to actually be forum posts or articles some where much easier to search and assess for quality ... but unfortunatily they arent and they do hold valueable information if you wnat smth more or less up to date as the creators actually might earn something from it whereas most articles are written for free

[neon oriole]

note how dominating vim like are over vscode :p , where as vim certainly fall in the category easy to use and flat learning curve (neovim and vim are separated out but essentially up to a version ago interchangeble)

[kind jacinth]

I feel like I'm the weird guy for doing all my dev work in sublime

[frozen flame]

I mean sublime is fine, it's just nothing special

[kind jacinth]

Yeah I just never see anyone else using it lol

Everyone's arguing between vim and vscode and I'm just sitting in the sidelines

[drowsy elbow]

Most annoying thing ever. Hasn't been updated in a year and the whole api changed lol

[drowsy elbow]

Yeah the learning curve of VI is flat, but it's flat at the top lol

[drowsy elbow]

@frozen flame are you my old co-worker? he had the same name and attitude

[frozen flame]

Unless your last job was in roofing, probably not

[drowsy elbow]

Haha, guess you're his lost brother then 😄

[neon oriole]

since there are people using vim , there has to be a line connecting the not nowing anything to that top flat line, its just unnessesary steap,...

and i had a typo in the prev one : well , typo , i meant to say dont fall in the category easy to use and flat learning curve

the only editor harder to exit then exitting vim when opened the first time with nvim filename.txt //this will skip the startup screen telling you how to exit is : ```
ed

seriously i usually end up having to kill the p process in the case of ed no clue how to exit that one (ctrl +z works to background but that all i got without looking up the manual)

[sturdy ingot]

It's basically the same as :q in Vi, but Q is like :q!.

One uses dates and one doesn't, so if you want to keep use the date portion use java.util.date

Apparently neither should be used; it's suggested you use this instead: https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/time/package-summary.html

so my professor, said i should know matlab by now, despite being a fully EE student and having literally 0 experience with matlab, I coded like 6 basic af beginner things in intro to programming on C++, but that was literally like 2 years ago as a freshman and i have no idea how to code anything in matlab
either way, if you know where to tell me to look for resources or just help me with this assignment

I have to "Write a program in MATLAB to initialize a 1-D array with 10 random numbers and find
the range (R) of these numbers where R = MAX – MIN. MAX and MIN are two user
defined functions that you write to find the maximum and the minimum of these 10
numbers."

[cyan niche]

Google it and your professor is whacked the fuck out

My professors don't expect me to know Matlab well and I'm in grad school

hmmm

i need to like make it look like its not plagarized too lmao

[cyan niche]

Well I didn't say copy it

"how to initialize a 1-d array in Matlab"

"how to generate random numbers in Matlab"

I'm guessing you can figure out the max/min functions from here

How do I reverse engineer a really old abandonware (seems to be some word processor)

Not necessarily the code itself, just for now the file format could have been enough

Like, by creating files with specific pattern and compare their hex layout, I found that there are 20-24 bytes that are related to adding underlines

I have figured out that 12 of these bytes specified the line shape and coordinates to draw them, but I am lost with the other 8-12

It seems that those bytes were storing the line shape index and start coordinate in another format, but I am not entirely sure about that

[red mulch]

Pretty much what you're doing. Make educated guesses, iterate over it.

also feel free to ignore parts of it you don't care about

#I have no idea what these bytes do, but it doesn't seem to affect the outcome, so I ignore them!

[red mulch]

wirte me a program in matlab to track a series of objects that have intervals (extents). When intervals intersect, they should be changed/added so that each interval has the correct reference count.
You should then be able to report the total number of extant blocks (the size of the intervals/extents), along with the number of allocated blocks - the size of the extents multiplied by the reference count.

There's about 2 million extents to track 🙂

what if i complete all these courses?

[kind jacinth]

No idea about that but I always reccoment cs50x and 6.00x on edx

Cs50 is more broad and probably more interesting for beginners while 6.00x teaches fundamentals really well

Oh looks like 6.00x has been renamed to "Introduction to Computer Science and Programming Using Python"

[simple canopy]

Whilst I think Python is really easy to get into, I am actually not a huge fan of it (like I really dislike its syntax) and I more often than not end up suggesting JavaScript which is also not that hard to get into.

[kind jacinth]

Python is a programming language for mathematicians and scientists. It reads almost exactly like how you would describe an algorithm in a CS paper. Whether that feels intuitive to you or not depends on background.

Personally I feel like python reads like well written perl. I've also written like <150 lines of JS

[simple canopy]

How do you like it? I’ve personally written over 200K lines of JS

[kind jacinth]

I don't really have much of an opinion of it. It looks like code.

Probably my only impression is that it there seems to be a lot of pitfalls to avoid to not code yourself into a corner, but that seems to be alleviated by typescript. Altho that itself is a weak "feeling" that I can't exactly back up well

[simple canopy]

yeah. That’s why TS is so cool. And yeah sometimes JS’s memory management makes little sense to me and I fall into traps I only realise I fell into much later

[inner wraith]

Hm. Well if we're throwing opinions around...
Python's nice to write - clear and concise - but it's still very slow. PIP's great for the most part and it's possible to build a great project on well-known libraries without drowning in dependencies to audit due to its strong standard library. Type hints help a lot.

Javascript is faster with V8 but NPM is a mess, as is dependency management. The syntax is also a bit of a mess and I've fallen afoul of ASI a few too many times to be pleased with it. The standard library is comparatively anemic and there's an NPM package to do basically anything, and hundreds of dependencies in a project is far from odd. No typing was a definite pitfall for the ~60k backend project I had to help clean up though I'm assured Typescript helps.

C#'s interesting. I haven't done a lot with packages because I haven't needed to - the standard library is quite good and my projects have been small. I'm uncertain how many idiosyncracies are from VS versus C# itself. The language itself is less flexible than say Python but having typing by default has been pretty nice. There's more boilerplate than in Python or JS.

[kind jacinth]

Python is slow, yes, but that shouldn't really be a consideration unless you've demonstrated you need the speed -- that's premature optimization imo. Pythons strength is in it's speed of iteration. You can prototype and drastically change things around very easily.

Second, python IS fast. If you're not using fast, cpp based libraries, then you're not really writing good python. This is why python is the premiere choice for data manipulation and ML.

[inner wraith]

I say slow but I do have a tiny project serving 1k reqs/sec on one interpreter - it's enough for some.

It is slow. And you're mistaken if you think compiled libraries makes Python good generally, any more than Bash is good if you make sure to use it solely for pipes.

You can certainly use them to do things quickly with Python as an interface - NumPy for example.

But that's NumPy and the incredible work done on it, not Python

[kind jacinth]

If your program can't make heavy use of numpy (whether that's scipy, opencv, pandas, tensor flow/pytorch, etc) it really shouldn't be written in python

[inner wraith]

I don't always have the luxury of being able to turn to a big C library that does what I want and for certain tasks like webservers, games or the like the brains and performance-critical components are written in Python.

[inner wraith]

We'll have to agree to disagree.

[kind jacinth]

Nothing performance critical should be written in python imo

It is fast particularly for data processing and again, it's strength is in making MVPs

[inner wraith]

It isn't fast for data processing.

This is why data processing tasks in Python hand your data off to the libraries immediately and you do your tasks against what they represent to you.

[kind jacinth]

I'm saying python is fast bc you can hand everything off to faster libraries. You're saying python is slow bc you have to hand everything off to faster libraries. This is a pointless conversation.

[inner wraith]

The former is not correct.
The latter... No. I'm saying Python is slower than the alternatives mentioned. Libraries for fast processing do not mean the language is fast.

I still use Python for stuff. It's fast enough for many of my use-cases.

[cyan niche]

I've never had to wait on any python program I've programmed

Skill issue.

[twilit beacon]

completely agree, though i would probably suggest c++. js syntax is also relatively weird. as for the available libraries and ai/ml being a lot of times really simple and beginner firendly (like in keras), that is a huge plus imo, even for professionals its incredibly helpful as its a really quick way to make and test a prototype

[cyan niche]

Don't learn C++ learn Rust

[kind jacinth]

Cpp is employable. Rust is better.

[twilit beacon]

perhaps

[cyan niche]

Rust will be more employable later

[twilit beacon]

[cyan niche]

[twilit beacon]

is rusts syntax similar to that of c++?

[hollow basalt]

rust

[cyan niche]

yes

[unborn imp]

Realistically, don't worry about the speed of a language unless you know going in that gonna be doing some really heavy number crunching. I've used Ruby - an infamously slow language - professionally for over a decade doing web dev related stuff, and in a surprisingly large number of cases it's fine.

(It's also not nearly as slow as most people seem to think it is, especially when turning on JIT compilation in the latest versions.)

Rust is a great language. It also has A LOT going on. If you don't know anything, I'd go with a friendlier language like Python or JS or Ruby. It's easier to keep motivation for learning up when you're making progress, and Rust has a lot of things that'll completely block you until you learn how it works.

[fading osprey]

This right here ^^

I spent a lot of time learning to code in C#, python, and then JavaScript before I finally felt at home with a language.

After a couple years with JS I got bored, heard good things about Rust and decided to make the leap, it took me over a year of consistently trying to make a semi-usable CLI app which displayed a countdown timer until the next rocket launch was supposed to happen.

it was very slow going, and took probably a good few years off my lifespan at this point from trying to figure out all this new stuff that I had no concept of from my time working with JavaScript.

[inner wraith]

Pretty much. If you need thousands of requests a second in server throughput you can use multiple workers.

...And can probably afford a few extra cores for them to live on.

There are exceptions - I wouldn't implement software video transcoding in Python, JS or Ruby - use ffmpeg or something. [3D] Games... just don't bother, use Java, C#, C++ or the like.

[unborn imp]

Depends on the game. For 2D games, use whatever you want. Python is super popular for roguelikes. CrossCode runs on Switch and uses JS. Lots of JS games on Steam running in an electron wrapper.

[inner wraith]

lol I amended my message at the same time

I detest JS+Electron with a burning passion (comparatively hard on CPU) though I can admit it's possible for games that don't require a lot of compute performance.

[unborn imp]

The V8 JS runtime is actually phenomenal. It's optimized to the point that you don't actually get that much more performance by using a compiled language in many cases.

[inner wraith]

It can sometimes be similar to compiled languages.

[unborn imp]

The garbage collector is the big thing that trips you up

[inner wraith]

In the general case it is not, though impressive for what it is

[unborn imp]

That, and the warm up period for the JIT.

Although you get that with Java and C#, too.

[inner wraith]

Ah, but with both of them you can have in-process parallelism... and they're both generally much faster.

One does not need a Ferrari to go grocery shopping but this does not make a Kia Picanto equivalent to it in all aspects.

[unborn imp]

I'm mostly tired of seeing people advocating for rewriting Javascript applications in Wasm when the speed gains just aren't that substantial for many applications.

[hard rose]

Can we just settle this by agreeing that Microsoft JScript with wsh was the best version of js and it should be used for everything

[inner wraith]

No

[hard rose]

Plus benefits/pay are good especially considering I just graduated

[cyan niche]

My first internship I was working on some weird proprietary database system that had a syntax based off of Pascal and I got paid like $40k that year to waste a year of my life learning it.

Looking back, I didn't have a choice, but holy shit there were people working there for twenty years with that system. I was like bro you have no relevant skills in anything else

They're basically stuck at the company because no one else uses it

[hard rose]

Yeah, trying my best to stay out of the pascal stuff. The syntax is so wack 🤣. Got a lot of ppl at my company that have been here for over 25 years. A few over 40 yrs

[cyan niche]

How much?

Because no way I'm touching something like that for less than $300k

[hard rose]

TF IS THAT 🤣

[cyan niche]

You're basically sacrificing your own relevance to work on systems like that, so the compensation needs to be a lot higher before anyone should really consider it career wise unless that's what you really enjoy. Like I'm thinking about quitting because we're not using Vue or React where I work.

And I think at this point I wouldn't work on anything but vue

[hard rose]

If I were only using pascal I'd agree. Only planning on staying for another year/ year and a half as is. Waiting on gf to graduate then moving.

Apparently there was an attempt at writing a new one with a consultancy firm and the proof of concept took literal hours to respond to queries and as such was shelved for all of eternity in favour of a specific old version of SQLWindows.

Considering what they were doing and the industry I have no idea how you could fuck up a rewrite that badly but I'm sure it was all very entertaining if you weren't paying for it or involved with its development.

Family has some old hard drives they want the pictures off but it's scattered all over the place in the os and I don't want to search through each directory

[azure mason]

I mean you can use file explorer to search file types

if they're pictures just search .jpg .png

or if they're camera photos you can search for the raw files

[silent gust]

You could make a program

Good idea, but I should have specified there's a lot more. Spreadsheets, word docs, videos, etc. But ye that'll work

[red beacon]

I worked at a small company as a developer and the sysadmin automated a lot of his work using Powershell, he even automated some of the dev environment's setup using it and wrote some tools to measure system load for our servers. I was really impressed by his use of it and how powerful it is if you're in a windows environment

[fiery void]

This is exactly why I know powershell as well

[fading osprey]

[cyan niche]

It's pretty readable

[cyan niche]

So like, when you want to add comments, you want to add useful information

Avoid comments like "Creates record in database". But something like, "Also generates computed values [values] on creation" may be helpful.

Or like, "Records are also created from DB function Create_Record"

[silk eagle]

or for explaining math (unless your project is 90% math) or workarounds that might not be immediately obvious

[grim wind]

function permute(str, key, obfuscate) {
    const chars = [...str];
    const indices = Array.from({ length: chars.length }, (_, index) => index);
    const seed = fnv32(key);
    const rng = mulberry32(seed);

    for (let i = chars.length - 1; i > 0; i--) {
        const j = Math.floor(rng() * (i + 1));

        [indices[i], indices[j]] = [indices[j], indices[i]];
    }

    const result = new Array(chars.length);

    if (obfuscate) {
        for (let i = 0; i < chars.length; i++)
            result[i] = chars[indices[i]];
    } else {
        for (let i = 0; i < chars.length; i++)
            result[indices[i]] = chars[i];
    }

    return result;
}

Does anyone know how to make this algorithm go faster? It's performing very poorly on processors that do not support scatter and gather vector instructions

[inner wraith]

Run a profiler and find where most of the execution time is spent, decide if those bits can be replaced with a less expensive alternative. If most of it's offloaded via FFI to C or whatever already and you can't change algorithms... good luck, pick your preferred compromise - consider if you can farm it out to a subprocess and return when it's done if you need higher throughput (will do nothing for latency). Else, decide if not running it on processors not supporting vector instructions can be unsupported, else... pick your compromise.

[grim wind]

I've done a profile now. Seems like the indices generation take up a lot of the stack temporality

I love how my friend was like hashing functions can be bad for performance

But the CPU doesn't even care. He literally counts it as 0 ms

Anyone ever used this library?

Is it not Barcode(code, type, boolean)

[rich trail]

Is anyone able to help me figure out what I need to change with this python code snippet (uses pandas) so it still does everything but sum the values? Removing .sum() didnt work lol

[drowsy elbow]

What?

[drowsy elbow]

new NetBarcode.Barcode(...) is the exact same.

[cyan niche]

Oh I see, it just set its to 128

[drowsy elbow]

Lemme try 128 and see if that works

Not even sure what a 128 barcode is tho

Nope same error

[rich trail]

barcode that can encode all ascii characters

[drowsy elbow]

Ok I managed to fix it by setting the boolean to false. Not showing the label.

Still a bit weird tho.. Anyways, I can continue now 🙂

[cyan niche]

Probably has to do with this and what fonts you have installed

[drowsy elbow]

That's not an argument null exception, and the exception message is different. Anyways, it could be related if it gets caught higher up and then throws something else

[cyan niche]

Well, it would be a null argument exception if defaultFont.Name is null

[drowsy elbow]

Hmm, didn't think of that

[cyan niche]

Try running that code in a vacuum and see what happens

oh uh https://github.com/Tagliatti/NetBarcode/blob/master/NetBarcode/Barcode.cs

[drowsy elbow]

I assume that's the case

FirstOrDefault and then say it can't be null !

[cyan niche]

Unless the default is null lol

[drowsy elbow]

FirstOrDefault means if nothing is there, it's null

It would be better to just use First() in that case

That one will fail if there is nothing there

Oh well, it's fixed for me now

[cyan niche]

My brain parsed the ! not as code !

whoo, also I hate this slow mode

[drowsy elbow]

The ! means "I know what I am doing compiler, it's not null, trust me bro"

Cuz if they didn't add the ! they will get a warning with "Hey, this might be null"

It's a recent feature, but I don't really like it tbh

[cyan niche]

Remove the group by and everything after it, then just do the sort

Ohhh yeah I'm not the biggest fan

[rich trail]

Just did the change and now Im getting an error for some code further down the script that I wasnt getting previously 😭

Did I make the change properly or did I mess something up?

[cyan niche]

well you can't just have a variable floating around by itself

[rich trail]

are you referring to grouped_hours_rp1?

[cyan niche]

The code below it looks like it counts on the fact that it's already grouped, so you removed the group

Oh, does that print it?

[cyan niche]

ye

[rich trail]

I guess in this case all Im doing now after the change is sorting the values yeah?

Ahhhh yeah I dont even have a reference to the federal wages anymore....

I updated it to this so I can still keep the federal wages reference, but still getting a new key error down the line

[rich trail]

Thats just executing the variable I think?

[cyan niche]

Ah, it saves the data to the dataframe

I'm not sure why you would need the next part of the code if you're removing the sum

it's essentially joining a dataframe to itself based on its aggregate values

[rich trail]

I very well might not lol

[cyan niche]

You're no longer aggregating, so there's no new data to join

[rich trail]

Ahhh ok, will try removing the second part
edit: Oh damn doing that will mean I have to rework some part a little further down. I am unequipped for this 😭

If in a database I have 2 tables:

Table student
-- id (PK)
-- student_id (string, not unique)

Table student_info
-- id (PK)
-- student_id (string, not unique)

Is it possible to join 1-1 in Java spring boot using either @JoinColumn or @OneToOne ?

Technically, there can be multiple rows with the same student_id in both tables (from the db schema) but it's not possible from my code implementation

[red mulch]

why is it a string not an int?

[patent silo]

Unless you're going to be doing some mathematical operations on the ID, it's usually best to store representational data as a string.

[red mulch]

ehhhh

my main issue is the PK just says PK

so it's not clear

[patent silo]

I mean what's the issue with the primary key being an autoincrementing ID?

[red mulch]

no issue at all

but why would the linking ID be a string

[patent silo]

I mean, so long as there's a unique key constraint for the student ID that shouldn't be an issue

[red mulch]

If the ID is an int and the relational ID is a string, then that's stupid

[patent silo]

here's a better question, why would the ID have to be an integer or some other type?

[red mulch]

it has to be SOME type

and it doesn't say.

[patent silo]

That's true as well

[red mulch]

if it's an integer it should be an integer type

if it's an ID that's a string, sure, don't care.

[patent silo]

What's more concerning is there's no unique constraint on the student ID though

Why would you have two students with the same ID?

[red mulch]

yeah this is ... very bad

student id and student id

[patent silo]

Yeah, if you're gonna havea student table with identifier, the PK is given to be unique, but your student_ID should definitley be unique

Else how are you gonna make proper joins..

[red mulch]

I mean it has an ID. That's a duplicate field. and if it isn't a duplicate, your database is fundamentally broken.

[patent silo]

Only scenario I can think of is maybe you're relying on a GUID-like ID that's designed to be unique when generated

[red mulch]

ehh, I think you're overthinking it

[patent silo]

I mean yeah for this that would be overkill

[red mulch]

not that it doesn't happen, but even then it's stupid, because it should be named something like student_initial_id or whatever else to indicate it's something different

if it's not obvious, it's wrong.

[drowsy elbow]

Maybe id is the id of the student, and student_id is the id of their best friend 😂 😂 😂

[red mulch]

Not necessarily best! Because it's not unique....

[fading osprey]

I mean, even the naming convention isnt the best

if the table is called student then (to me) the obvious name of student_id is just id, because it would be student.id anyway, right?

none of this structure makes any sense to me, why is student_info being kept seperate to the student entity? surely thats the most important thing you are likely to query, so just having a table that stores the same data a second time under another name is a bit silly?

[drowsy elbow]

It shouldn't be unique if it's their best friend. Multiple people can consider one person their best friend 🙃

[red mulch]

True enough!

[drowsy elbow]

select * 
from student l
inner join student r
    on l.id = r.student_id
where l.id = @myId

(0 rows affected)

😦

I think I joined it the wrong way around

Oh well, havne't done sql since I left my previous job

So I have a Vulkan program that is supposed to look like this

Randomly it will look like this.

I have done the following debugging steps:

• Dumped the buffers before handing them off to my buffer code
• Dumped the bytes after being copied to the buffer returned by Vulkan
• Rebound the buffer and dumped the bytes
• Flushed the memory cache
  (All of them showed no corruption)

Nothing works, it just randomly does that. It sometimes takes a dozen tries but it always happens eventually.

Does anyone have any idea what might be wrong here?
