but you can confirm it yourself by adding in the time to the equation and sending yourself a couple of emails a few minutes apart
Invoice {{ 'today' | date: '%B %d %Y %H:%M:%S'}}

Thats actually what I plan to do. my goal is to convert all my invoicing numbers to date/time

I guess its technically the subject line of an email so there's no way for it to change after sending.

yeah once its sent its just text.

Does that also apply to the body of the email?

Anyone know of any free write-only public log file services?

I need to be able to accept semi-private log files (Brower Command Line data that can contain search queries) from users in a way that allows them to upload-only, and that I can read later. Are there any existing services for this that I use and can point my github issue reporters for uploading?

Alternatively, I could ask users to encrypt their log files using public key encryption but I don't want to encrypt the local log files by default so that more tech savvy users can review the log files themselves.

Suggestions are appreciated, Thanks in advance!

add a log upload tool inside your application? let them upload through a website controlled by you that you do encryption inside before passing stuff to permanent cheap storage?

Several, but overall the absolute state of some of their services & developer tooling. I keep having to re-learn the lesson that a lot of things are broken and will leave you stranded as soon as your use-case strays outside of mundane/rudimentary.

Amazon has such a massive marketing budget - its easy to be suckered into thinking things like Amplify, Codepipeline, AppSync etc are viable when there are 100 prominent influencers on medium and youtube claiming they are the bees knees.

So many services that just dont work - half-finished, half-baked solutions that were seemingly incepted when some company paid an AWS Solutions architect to build something, and then released to the public and never fixed/maintained/updated again... at least until a new company comes along, tries to use it, gets stranded and pays another solutions architect to further develop the service.

red mulch
#

oh you better believe it

#

especially if it's not a tier 1 amazon app.

#

we used amazon uhh... whatever the phone thing is

#

no api. Login uses an AWS login, so if you're using/testing it and you login to AWS it fucks it up. UUGGGHHHHHHH

#

a lot of things are just thin veneers over a bunch of lambda functions (I'm looking at you code pipeline)

#

The key is to stick to the "basics" tier 1 services and go from there.

#

ran into something like that at work a month or two ago

#

they just randomly made breaking changes to one of their SDKs with no warning and didn't even mention it in the changelog

#

then when i complained to our rep and in a ticket their response was straight up "we can change things whenever we want and actually it's your fault for assuming we follow semantic versioning"

#

#

the SDKs are usually pretty poorly documented and maintained

#

but that is definitely the most egregious I've seen

red mulch
#

oooh, yeah, they are.... .... useable.

#

but I haven't done AWS for like ... a year?

#

and I have done azure, and fuck I hate azure. It's like a microsoft guy from 2005 heard about cloud and was like "oh shit we better make some cloud"

#

AWS as discussed has its problems, but it has the feel that it was at least core designed by engineers, not button mashers

I want to employ your guys' brilliance - I'm working on a birthday scavenger hunt type thing for my wife. I'm making it in Python, if that matters.
I already have 10 steps coded that range from silly (fake) questions, to substitution cipher, ASCII85 encoded strings on notes around the house, Bacon Cipher, Satisfactory coordinates to a clue, Spotify playlist QR with titles as the clue and so on.

She's into geeky things, video games movies and the like. She's not so much into coding, ciphers and all that, but I figured this might be a fun way to introduce her to the concepts here.

I'm wondering if you might have any other cool ideas of how I can hide clues to stuff.

Ideas I've been considering but too lazy/stupid to implement: AR model with a clue hidden inside it, youtube videos where the clue can be decoded by skipping to the parts in a correct order, geocaching.

advantages of being on a non-english country i guess. but it's probably because we just use matlab for simple stuff. 🤣

Might be a stupid question. But I created a Docker container for the data science project my team is working on. So we have to deal with less merge conflicts when working on the same notebook and so we can share one requirements.txt file that works on all machines (because of different operating systems). We like to use VS Code for development because it has an easy integration with Git, decent highlighting, and integration of handy plugins like GitHub Copilot. But.. once I select the Jupyter server of the Docker container as the interpreter, the intellisense of packages installed with pip install are lost. Only the most basic packages still have intellisense since their source code is stored in ~/.vscode/extensions. Now I don't really want to use the Dev Containers extension because you lose access to git integration from the terminal/extensions that way. But would it be possible to select the python interpreter of the Docker container as the python interpreter for VS Code? Or would it be possible to add the source code of other extensions to the ~/.vscode directory? And would it be possible to update these automatically when starting the Docker container according to the requirements.txt file?

Anyone developing for scientific research in emacs? (Very niche field I’m aware)

shadow rapids
#

Scientific computing for fluid dynamics

#

But to be honest, I develop on my laptop in VS Code, then copy paste the whole file into nano when I SSH into the HPC

#

Ping me btw

brisk thunder
#

@shadow rapids ahhh I don’t work in HPC mainly computational math (working with a perturbation algorithm for a graph network)

#

It makes sense why you would use nano though, you don’t really need to do extra editing once you have it established in vscode

#

I’ve started using emacs for latex and python but I still run MATLab and R in their respective ides

shadow rapids
#

I really hate the default editor

#

Problem is, I use macOS, and MathWorks has not released an Apple Silicon compatible CLI MATLAB. Which, in my opinion, is completely embarassing.

brisk thunder
#

Their community is super nice too, similar to rust

shadow rapids
brisk thunder
#

Julia is very fast compared to Python, and it’s speed is near comparable to C. The documentation is there and it’s really good for establishing macros and runs with LLVM

#

Obviously nowhere near as good as C but better than matlab

#

You could develop without Simulink kekw, but why is Simulink so vital to you?

#

I’m sure there’s numerical libraries for any other language that’ll offer you the same endgoal, but is it just the graphical interaction you prefer?

midnight wind
#

and modeling

shadow rapids
#

I don't use Simulink

midnight wind
#

it's not just the graphics, there's many other parts of it that are useful

brisk thunder
#

I do modeling and we don’t need Simulink, my models are for neurons/neural networks

#

We just use matlab because it’s easy to code a quick simulation for testing but not implementation

midnight wind
brisk thunder
#

I run data sets from physics engines. But there’s literally FreeCad

midnight wind
#

freecad sucks

brisk thunder
#

I think Simulink might make it an easier front end but it’s not the only option

midnight wind
brisk thunder
#

I mean, then why not C

#

The libraries have existed for years, same with Fortean

#

Fortran
MATLab uses a lot of the open source C libraries

midnight wind
brisk thunder
#

You can draw them with hand and figure out how to model them

midnight wind
#

that's a waste of time when there is software to do it for you

brisk thunder
#

The EE I know who’s been working with circuits uses a software specific to their company so I don’t know why you use matlab

#

Are you in school? Because then that makes sense

#

What is your job or end goal?

#

Because if you need matlab then you can just use it, but I was just offering a solution to someone who wanted a different solution than matlab

midnight wind
brisk thunder
#

Well, if you’re in school. There’s nothing stopping you from building that alternative for the future if you have time. Hopefully if you’re still in school, then by the time you go to a company you can just use their implementation because they usually have it scaled to their entire operation

I have a question regarding testing. Let's say I have a test case where i have to update/manipulate data a certain way and check if it updates correctly. However, the test data should be reset to the original state so the test can run and update it again. Should I perform the reset before or after the test?

For example in jest's context:
beforeAll() vs afterAll()

anyone good with MySQL Queries, got a strange one I can't thing of a resolve for

It's for views, I'm querying the views table and grouping by country and date, to graph, but if I limit the query then it will limit the amount of days of data it shows, but i want all days of data in a range, just for a limited amount of countries

This seems like a better solution I got from chatgpt after prompting it a bit, but I get this error [42000][1235] This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

# vestal spire I have a question regarding testing. Let's say I have a test case where i have t...

Typically I use before methods to setup and after methods to tear down / cleanup. Since you are talking about resetting state to default, I’d use after.

Quick note on all methods, they are used for the test suite / file in Jest. So you’d use beforeAll todo setup once for multiple tests and afterAll to cleanup. When you need todo it per a test then you use the each methods, beforeEach and afterEach.

On the Jest docs there is a helpful section called order of execution that demonstrates when every method runs using console logs.

Would it be possible to run a game’s logic and how often it checks for input at a higher rate than the framerate? Wouldn’t that reduce latency? Or is there some problem with doing that?

wind horizon
# carmine lantern can't seem to figure out how to give this the proper user input

Yup what Pepe said, looks like subString requires a start, but end is optional and if end isn’t passed it goes from start to end. Since you passed 3 characters and start at the 3rd I’m guessing that shortEntry is now an empty string and matching the first item in the books. Try changing it to subString(0,3)

Idk Java well, but looks like the code is also trying to stop the loop by making X the length of the array. You can probably use a keyword like break to get out of the loop more elegantly.

If you have a local IDE with debugger it’ll help a lot with inspecting the code while running it, but if you don’t a quick hack could be to toss in some println to print the current variable values.

I switched if(books[x][0].startsWith(shortEntry) to if(books[x][0].startsWith(entry) and it passed the checks

different variable?

delicate basalt

so for your array index, you want an int. currently you're using a double. im just saying it mnay be best to make a new variable for your index (you don't HAVE to tho 😊 )

carmine lantern
#

ahh ok, the problem is I need to be able to input doubles and get the averages of doubles, not integers

delicate basalt
#

OHso you'd want to do an explicit typecast everywhere you're using average as an array index. just put (int) in front of it

delicate basalt
carmine lantern
#

got this now

do I need to convert the double into a String and then convert the String into an integer?

delicate basalt
delicate basalt
#

gonna say this rn: don't feel bad if you don't understand arrays right away. it took me a solid month in school to figure it out

#

oh i forgot! you'll need a new import statement to use Scanner

#

at the top of the file, add import java.util.Scanner;

#

i think i see some confusion... when i say array index, i mean the spot in the array where the data is located, not the data itself, example: in array[x] = 2, x is simply telling Java where in the array to stuff that 2

#

if you were to print the contents of array[x] after that, java would print a 2

carmine lantern
#

ahh ok

#

uhh the only thing I have now is a "bad operand for binary operator on line 29

wtf

also when I try to get an average it just tells me "no numeric values were entered

that's weird

i've never cared for java bc of shit like this

give me a sec. i would already have IntelliJ but i wiped my computer recently

I hope you are doing well and having fun as per your tube channels which we as a family love to watch.

My name is Markus and I’m from South Africa.

We all our pcs and electricity costs are getting extremely high, not just for personal use but for business use as well
What if I tell you that I designed a new energy source which we all can use for our pcs and use later as a source for businesses as well.

This means you wont ever have to pay for electricity but just for maintenance for the design.

I would love to have an opportunity to have a full in depth chat to you regarding my design and see where our chat leads us

Thanks again and always stay as your are

ColdFusion Markup Language

ColdFusion Markup Language, more commonly known as CFML, is a scripting language for web development that runs on the JVM, the .NET framework, and Google App Engine. Multiple commercial and open source implementations of CFML engines are available, including Adobe ColdFusion, Lucee, New Atlanta BlueDragon (who offer both a Java-based and a .NET-...

Hi guys. I've been working on a website project in java script... most of the stuff is done however there's some issues with the login service (database). I use MongoDB/Atlas. If there's anyone with experience, you can DM me and i can explain, or even call if it's not a problem. I don't think the issue is big, i think i roughly can point to the problem that's occurring, and i don't think it's a huge issue. I had an issue with the recipes, but i kinda sorted that out. Backend is kind of my weaker side, i haven't gotten the time around to play with it. If anyone wants to help me, you can hit me up! The project also uses node.js code as well. Any help would be appreciated!

The website is about food products. And no, this won't be a website that i will use.

Hey guys, I’m working on a project that involves pulling data from several rest APIs and comparing the data across them. We are trying to use a DB with it and I’m trying to find the best way to do this. Currently we are using Python but I was curious to see if there is another better way.

If you have any insight, feel free to send me a DM. I would love to bounce ideas off of someone with more experience.

Checking on the Facebook developer site looks like connect is for sharing account info, friends, etc often used for signup/login with Facebook. If you have a pre-made auth solution, like Okta, Firebase, AWS Amplify, etc they often have a Facebook option.

I think I may know what the source is though. Could it be from facebook's advertising tracking? I think its called pixel?

If you posted the site I'm sure someone here would find it in about five seconds.

Tracking pixels, 3rd party comment systems, maybe GTM, there's a whole bunch of options.

mainly because I use html instead of real code linuth

i can also create a gui in seconds but it might just be an empty window

is that really a gui tho

not scared

it hurts my ears

#

i have really bad noise sensitivity

bitter edge

how many times do you have to hear that little noise for it to hurt your ears

#

then shouldn't fire alarms or someone screaming be worse

echo fog

once, depending on how loud it is

if there's a fire alarm i will have a meltdown on the spot

bitter edge

what did you do in elementery through high school when they had drills

echo fog
#

i covered my ears, but i was able to not scream. Those weren't super loud though compared to the residence hall ones. I should have specified

#

as a small child i would scream at the vaccum cleaner and stuff but now i don't unless im really caught off guard

bitter edge
#

just cover your ears in the market

echo fog
#

yeah that's what i do

#

or wear noise cancelling headphones

bitter edge
#

isn't the silence to loud

echo fog
#

no

bitter edge
#

i don't know bout you but when I use my noice cancelling earbuds after a few hours I get that weird feeling in my ears when I take them off

echo fog
#

if im going somewhere crowded noise cancelling headphones aren't strong enough so i use industrial strength hearing protection but even that doesn't get rid of that wanting to scream feeling if people blast music

#

also, some noise cancelling devices are different than others

#

usually when headphones hurt my ears it's because of the way they're sitting on my ears

bitter edge
echo fog
#

i think it's my glasses

bitter edge
#

thick glasses

echo fog
#

people tell me my ears are small which is a weird thing to say to people but ok

bitter edge

get contacts smart

echo fog

maybe

idm wearing glasses because the headphone feeling is only after several hours

It’s always the sucky answer of “it depends” lol

What do you enjoy doing, that can help you get to at least a ballpark of what lang is popular in that field. With that said I’d suggest try to get 1 lang to a decent level before hopping all over, once you get over the core concepts most of them transfer to other languages just new syntax which you can often google / read docs to learn.

at a glance, im going to guess that the context you create in the test isnt the context that is used by the <service> to save the <user>

dawn flicker
#

You don't have to mock everything. If you're just testing if a user is created and saved then the mockContext.Setup(m => m.Users).Returns(System.Linq.Enumerable.Empty<User>()) should suffice. This should work, since a Mocked object doesn't really do anything

It's always with an extra \ in front of those extra signs to have them included in a string.

silk eagle
#

in Python, you can also put an r at the start of the string, same as you would for f-strings/u-strings, and it'll do a raw mode. Basically it literally just puts a \ before escape sequences and doesn't interpret them.

Haven't touched php in eons, but I assume somewhere there is a tool to do this without me writing the whole thing : I would like to generate "badges" for my association members : you can submit text and a (transparent background) picture and the tool will combine all that in the appropriate places I defined.

Does that ring a bell to any of you guys ?

And yeah, it is totally worth it since before that I depended so much on Visual Studio and I wanted to change that.
And the knowledge I got from that actually helps with basically everything else I wanna work with in C++, mostly. Like I could also make it work with Qt and/or Boost.

And the principle behind that can also be used in any other language, well almost.

@static marten Deutschland, Holland?

the clock.mainloop() blocks everthing.
Because the window would respond to the GUI actions
no more code would execute after that.

Did you verify if the "Script started" is printed after the GUI

if i am attempting to make a sound chips style module in go, with adsr stuff, would oto v2 or faiface/beep by recommended

faiface/beep is more popular, and seems more friendly, but it's based on oto v1, which isn't supported any longer

#

though the ebitengine from the same guy as oto uses oto, which is more popular than beep?

i guess it boils down to which design pattern i like?

OK so I have an idea - I find myself carrying around lots of USBs for various things and its kind of annoying. I recently found out the raspberry pi zero can emulate a mass storage device and people have been using it to run network drives into the usb port of their TV etc. I am thinking of using it in combination with this screen to navigate/create and select which usb drive you want to emulate. Thoughts?

image.png
#

with the ups-lite board on the bottom and a 3d printed case it should be a similar size to the flipper zero.

#

i'm certain someone else would have done this already. if anyone knows please send 😛

#

require('crypto').randomBytes(64).toString('hex')

#

is this a valid way to generate a secret

glacial tartan
#

you'd just need a big SD card

#

like 256 / 512GB SD card

ruby spindle
#

yeah it only needs to be small for my needs, I service printers and they only require like a 512mb usb to update firmware, pull data etc

#

but there are like 300 different models lol

glacial tartan
#

lmfao

#

tbf with the price of SD cards and the fact that you're limited to USB 2.0 speeds with the pi zero

#

you could get away with getting a cheap 512 GB then you have headroom to play with

ruby spindle
#

usb 2.0 is foine for my needs, although if it is quick enough to boot hirens or windows installation media it wont stop me from using it haha

glacial tartan
#

you just have to bare in mind that if you're gunna use something like circuit python or something it does have a few annoying things like you have to enable / disable read only file system if you want to write anything to it

#

i had that issue when i made the code for my Pico W USB rubber ducky

#

with wifi so you can control the ducky from your phone

#

it creates its own wifi network you can connect to and control it from your phone

ruby spindle
#

well, from my limited research it seems it just reads/writes to an image or bin file so pretty easy to use

glacial tartan
#

i just need to be able to get a Pico W that has a USB A Male instead of a USB micro B female

glacial tartan
ruby spindle
#

i generally use java for my projects, just my preference as its all im used to

glacial tartan
#

idk you might have to make your own storage driver

#

depending on if you can find one or not

#

i mean i made an aincent printer, wifi compatible

#

with a pico w

#

i wish i had like infinite pico Ws

#

they're so useful

ruby spindle
#

honestly i'd just keep it simple and just have java run the commands to mount / create / delete the image files

glacial tartan
ruby spindle
#

Can the pico emulate a mass storage device too you think?

#

would make it a hell of a lot smaller and use less power

glacial tartan
#

honestly, with circuit python you can do mf anything

#

there are sooooooooo many libraries for emulation

#

you can make the pico act like a fuggin printer

ruby spindle
#

interesting... I bet it would be pretty slow but for mass storage

glacial tartan
#

or tell the pc its a printer, it does everything

ruby spindle
#

yeah that would be weird haha

glacial tartan
#

then again you get like 2 MB of space to write your code

#

after you install an "OS"

#

and it doesn't have an SD card slot so you'd have to solder your own onto it

what was it?

carmine lantern

formattedCode = (areaCode);

#

It needed to be formattedCode = ("(" + areaCode + ") " );

so the parentheses of the area code would be implemented correctly

I'm doing a debugging exercise for a class in which a user enters a number, the result is supposed to be the sum of all numbers between that number and the number 5 greater
The result is supposed to be this:

The sum of all the numbers between 
     5 and 10 is 45
``` Unfortunately, my code has an error, so the code shows like this:
``` Enter a number >> 5
The sum of all the numbers between 
     5 and 10 is 5
``` I'm unsure of what the issue is.
Here's my code:
```import java.util.Scanner;
public class DebugTwelve2
{
   public static void main(String[] args)
   {
      Scanner input = new Scanner(System.in);
      int x;
      int y;
      final int GAP = 5;
      int answer;
      String userInput;
      System.out.print("Enter a number >> ");
      userInput = input.nextLine();
      x = Integer.parseInt(userInput);
      y = x + GAP;
      answer = sum(x, y);
      System.out.println("The sum of all the numbers between ");
      System.out.println("     " + x + " and " + y + " is " + answer);
   }
   public static int sum(int x, int y)
   {
      if(y < x) 
         return(sum(x, y - 1));
      else
         return (x);
   }

Python is still slower then languageslike c# and c++ because it’s a interpreted language. In most cases you won’t see the difference in a python application unless it’s just spaghetti code but it is technically slower

silk eagle
#

the way I sees it is, if you're doing a lot of iterations/loops, Python's speed will be actually noticeable. for mostly anything else 'see this -> do that' Python is a-okay. most of the time you're doing things in Python that you otherwise wouldn't be able to do without massive development time invested into a project, so doing it at all is faster than not.

# vapid sentinel define interpreted. Its compiled just like java and c#.

I think the misunderstanding is in that people think compiled languages = only to machine code. It varies depending on what exactly you're using (and admittedly I'm out of my comfort zone here) like cpython/jpython/ironpython/the other ones staredge but at least for CPython, code is converted to bytecode and then directed to P(ython)VM (/JVM/etc for others)

vapid sentinel

conda straight up compiles python to native instructions using LLVM

golden brook
inner wraith
#

Python (cpython in particular) does have a reputation for being rather slow though this is improving with time - speed wasn't really a priority until somewhat recently.

inner wraith
#

Well C# and Java will take your bytecode and compile it to native code for better performance buuuut just ignore that if you like putting things in boxes with readable labels

desert iron
#

The example was with a shape class and soke derived shapes like circles, squares, etc.
Plus a method which calculated the total area of each shape.

#

And the 20-25x improvement was with lightly optimized code for AVX.
Oh and btw: The code is still readable. It just doesn't use polymorphism but uses switch-cases, a function does know about the internals of an object, a function isn't small and does more than one thing.

desert iron
#

Even without AVX optimization you get 10-15x more speed.

raven pulsar
# vapid sentinel define interpreted. Its compiled just like java and c#.

It’s ran by an interpreter a system boot whereas c# is a compiled language and is translated directly into machine code. Technically speaking python is compiled but it’s compiled into byte code which is then ran by an interpreter. But the byte code can’t be directly executed by the cpu so it has to be interpreted by tools like pypy, and cython

#

Thats the only reason technically you can even say it’s slower. Cause it has no direct path to the system resources without first being interpreted

Polymorphism > switch statements is some bullshit made up by oop languages. Small functions when done right won’t have a performance impact unless it’s a extreme case and it should be optimized later.

#

im personally willing to argue that short functions are dumb and instead you should avoid nesting

desert iron
#

The "functions should be small" thing was also something that is weirdly handled.
I was adviced here at work to put basically every step into a seperate function which is then called. Even though it's just one step called once. And then having to nest the functions because of it but with logical names. That's what they mean with "functions should be small" and "functions should do only one thing", literally. So if you need certain steps for something, every step should be its own function which is called.

vapid sentinel
#

Making every step a function is just dumb and even if it’s a “rule of clean code” it isn’t done in practice.

desert iron

Well, at least in my company it is, or my department to be fair.
Was forced to do it.

# vapid sentinel Polymorphism > switch statements is some bullshit made up by oop languages. Smal...

the size of a function is less important than the content of it - at the end of the day, if you have 3000 lines in one function or split it up in 300, you're still executing the same 3000 lines of code

as for readability, shorter != better/easier to read either, people shouldn't follow rules blindly, use common sense and keep standards/conventions/rules in mind and follow them if it makes sense to do so

why should it be first project? or why should it be updated?

If you aren't using anything special from native it's probably not going to be complicated to do so.

stone rapids

Is it worth it to fight to get it to run in android studio as is and update incrementally, or just better to just try and update everything and work off of error messages? Main issue I've been having is the current packages being so old that they're not supported anymore

inner wraith

Depends on how big your project is I guess. But the SDK version and gradle version are aside from outdated dependencies.

Your project is in React Native. Unsupported packages are a fact of life :P

-You will want to update to not use those packages though.

stone rapids

Luckily it's a fairly simple app, just controlling LED lighting via bluetooth. But a lot of the packages are versions from 2015, so def working on getting everything updated

#

It was initially framed to me as 'the app works, android 13 just has an issue with bluetooth because they changed the calls' and then I start looking into the project and it's back on react v54.2

#

You shouldn't abbreviate short words

#

It's not like variables have a small character limit

#

There's some exceptions to this, such as interfaces, which should begin with a capital I: IPage

#

If you have something that's like:
ExecuteAndCheckIfInputIsValidForExternalPersonnel
it can be a bit wordy, but this isn't really solved by making shorter:
ExecAndCheckIfInputIsValidForExtPsnl

silk eagle
#

shortening the words also messes with autocompletions, have to remember which words were shortened and how they were shortened when typing the variable

inner wraith
#

I'm OK with very commonly understood abbreviations and will generally strip unnecessary words
...Like "ExecAndCheckInputValidForExternalPersonnel" is fine because "exec" is nearly universally understood by in context by novice programmers and the "is" wasn't doing anything helpful.

#

Though if your names are that long maybe it's time to refactor your code until your function names don't need to be complete sentences to be understood in context.

You can't use an interface in the context of a normal class and IDEs tell you what kind of class classes are.

#

What's the difference between IList and List?

inner wraith
#

List is an implementation

#

Why? Microsoft made it so in the stdlib

ornate summit
#

How's it implemented? In Java List is the interface with ArrayList and LinkedList being the two main implementations. It's really nice because it allows you know the mechanisms behind them and it allows you to pick for better performance.

cyan niche
#

A List is the actual implementation of a list, but by allowing for an IList interface, you allow the programmer to specify their own object which behaves like List but needs something special.

Suppose for instance you had a TrainCarList which contains a list of all train cars with a list, but this is a special list that you need to behave a certain way. So for instance a TrainCar object may support Next and Previous functions like a LinkedList, but you also want to be able to say, "Get me the third car in the list". By implementing the IList interface you can implement the Add/Remove operators to maintain the integrity of your LinkedList type structure for you.

The real advantage of this is that you can still use your TrainCarList in all places where you would use an IList. So you can use LINQ on your TrainCarList, or pass it into middleware functions that need to transform objects into JSON.

ornate summit
#

List should be the interface.

inner wraith
#

It isn't.

cyan niche
#

This is obviously a basic example, interface use becomes much more necessary when you start doing things like dependency injection.

ornate summit
#

I know what interfaces are, I've been programming for over a decade...

This is a discussion about naming conventions.

cyan niche
#

Oh excellent.

#

Well the I prefix makes it easy to tell what is and isn't an interface at a glance.

inner wraith
#

Tbh at least part of the reason why in C# is that if you don't you'll be mix-and-matching two conventions depending on what code you're calling if you don't

cyan niche
#

I realize that is dipping into Hungarian syntax, but it's a compromise I'm willing to make.

ornate summit
#

Your IDE does that and generally types with multiple implementations are going to be interfaces.

cyan niche
#

Well, your IDE may highlight it a different color, but it's more accessible to use a letter.

inner wraith
#

That's great if my IDE was your IDE but I'm not presently paying JetBrains money :P

#

VS is fickle and VS Code doesn't try

ornate summit
#

I'm not paying them either. :V

cyan niche
#

But do as you wish, I mean it's your code.

#

But the accepted practice is to prefix an I

ornate summit
#

Where's the official documentation for the C# PE files? I can never find it but the Java stuff is super accessible.

inner wraith
#

Like Portable Executable?

That's not really C# if so, that's Windows specifically

midnight wind
#

true

ornate summit
#

Yeah I'm not seeing anything about CIL.

inner wraith
#

Well you didn't say CIL did you

#

it's an ECMA standard

ornate summit
#

C# compiles to CIL.

#

It's the bytecode of C#...

cyan niche
#

CIL isn't bytecode

inner wraith
#

Actually it is

ornate summit
#

That's part of its Java heritage, a lot of the instructions are very similar too.

cyan niche
#

Nah it looks something like this:

       extends [mscorlib]System.Object
{
  .method private hidebysig static void  Main(string[] args) cil managed
  {
    .entrypoint
    // Code size       13 (0xd)
    .maxstack  8
    IL_0000:  nop
    IL_0001:  ldstr      "Hello World!"
    IL_0006:  call       void [mscorlib]System.Console::WriteLine(string)
    IL_000b:  nop
    IL_000c:  ret
  } // end of method HelloWorld::Main

  .method public hidebysig specialname rtspecialname 
          instance void  .ctor() cil managed
  {
    // Code size       8 (0x8)
    .maxstack  8
    IL_0000:  ldarg.0
    IL_0001:  call       instance void [mscorlib]System.Object::.ctor()
    IL_0006:  nop
    IL_0007:  ret
  } // end of method HelloWorld::.ctor

} // end of class HelloWorld
ornate summit
#

That's a form of bytecode.

cyan niche
#

Fair enough I was confusing it with machine code

#

u right u right

ornate summit
#

It's just a textual representation, like ASM is a textual representation of machine code.

#

Can you hook into the C# compiler like you can with javac?

cyan niche
#

Yes and there's an open source compiler as well.

ornate summit
#

That's neat, have you seen faucet? Does C# have something similar?

If you want a reasonably powerful system to run code for more time than that, either buy a laptop/tablet that can or pay for it really

has anyone got some experience in flutter? Basically I want to switch from Svelte but I'm not sure how hard it will be given I got a whole custom UI library built

sage vector
fierce rock
# sage vector In relation to web applications? Be aware that Flutter Web is not that great for...

well, I want to create a mobile & desktop app along my web app, so I thought flutter would be the best option. sure, electron exists, but I'm not sure about mobile. while svelte native exists, I'm not a fan of using in-built components as I'd like to have the same UI on all platforms. using a pwa is not really an option, given that it seems to have a different featureset on different browsers.

sage vector
# fierce rock well, I want to create a mobile & desktop app along my web app, so I thought flu...

It does sound like Flutter would be a fitting solution. I just wanted you to be aware of the issues there might come from Flutter web. E.g. since Flutter draws on one big canvas, you can't use it for web sites and expect any kind of SEO. Also, the initial loading of page/web application is going to be slower than e.g. Svalte since Flutter needs to download the libs needed to do the canvas drawing.

#

Also, making use of multiple threads are also not a fun experience with Flutter web. You can make use of web workers but need to do some manually handling here which is not that smooth

#

(Should say that I don't use Flutter but only Dart which I have been using/followed for near 11 years. I am active in some Flutter communities just because my Dart knowledge might be helpful for some issues) 🙂

fierce rock
sage vector
#

The canvas thing is because this is how Flutter basically work on all platforms. On mobile, it handles drawing every pixel so any kind of styling comes from Flutter and the libs. you are using. It does not make use of any components from the OS itself.

fierce rock
#

I'll probably have to give it a try to test things like accessibility, thanks anyways!

sage vector
#

Yeah. I recommend making some demo apps to test if Flutter can actually be used for your purpose

#

I recommend joining the r/FlutterDev Discord server which is a large Flutter community server with a lot of people that actually know about Flutter compared to me 😉

completely uneducated opinion here, but there's != and then there's !==, im wondering if the != there was checking if leftValue was literally the variable rightValue rather than checking if the values were different

cyan niche
# silk eagle completely uneducated opinion here, but there's `!=` and then there's `!==`, im ...

C# doesn't have a !== operator. Or put more accurately, its != operator is Javascript's !== operator. That's not entirely true because it will throw errors if you have different types being compared but that's the gist of it.

But what's what's happening there, is presumably that GetValue is returning an object an object and it's doing an object comparison, which is what C# does by default.

He'll have to override the Equals method to get it to behave like he wants (or use records in C# 9+) https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/statements-expressions-operators/how-to-define-value-equality-for-a-type

Tablets in general suck for IDE work, even with the keyboard covers and whatnot

But you can buy ones that can at least run the full IDE and run unsigned code outside of a browser.

I have a 1st gen Surface Go with a keyboard cover; same form factor as a 10 inch iPad. It's bad as a tablet! It's bad as a laptop! But it's magical to be able to just write code anywhere.

#

I use gVim to write vanilla JS and and Lua; don't want anything too heavy. Little browser games or Pico-8 cartridges. Was poking at Dart a little bit, reimplementing the SyncThing protocol. Just fun side projects.

#

It can do Rust, but the build times aren't great. Have to wait ten seconds or so for builds that would be almost instant on my desktop.

#

(To be clear, the 1st gen Surface was passively cooled and used just about the slowest x86 chip Intel sold at the time. Literally any other Intel tablet would be much faster).

I'm working on open-source open-hardware PC Fan controller. Mainly because I need one and the ones available on the market are either too expensive or don't have the features I need.
Question for you guys; Would you prefer to have a SATA power and USB connector on the board OR to have screw terminals so you can cut the cable and wire it individually?
I'm asking mainly because sometimes you don't have a USB connector on the motherboard or it's one of those "weird" headers so you wouldn't be able to use off-the-shelf cable...

When building multi threaded, how much ram per core is reasonable? I am having issues at about 1.5 G per core.

#

Maybe less than that.

cyan niche
#

I'm not sure what you mean.

#

Memory and CPU cores are two different things.

#

And when you multithread something normally you're taking something in one block of memory and processing multiple sections of it concurrently.

rancid nimbus
#

Ok, for one instance of a gcc compile out need to have a certain amount of memory allocated so it can build. If you have more CPU cores, then you will need more memory to utilize all your cores. I am trying to determine how much ram I want for my machine.

unkempt coral
#

Depends on what you are compiling and on which architecture. But you could safely spawn more threads than you have cores without seeing any major issues.
For example when compiling kernel or a large project, I often "run" 99 threads but since my CPU has 8 cores, there is little difference between 99 and ~20...

inner wraith
#

Please put a diode on it if you do add screw terminals though.

unkempt coral
#

I'm making multiple variations of the board for different use-cases so people have options.
I guess for the PC probably the most useful would be SATA power connector + USB header

#

And essentially it's open-source open-hardware project so after the initial release, hopefully the community provides some feedback and suggestions on how to improve it further 🙂

Hey guys i need advice:
I am trying to make a simple project that basically adds authentication and logging system to software defined networking controller layer. Basically protecting controller layer from application layer by adding username/password and logging system using blockchain. Anyone has any advice where i can start with such a project? I am using mininet but i am not very advanced in this..

i want to use it as a database

silk eagle

its such a specific topic that you'll probably have more luck looking in blockchain-specific development places, but I dunno where to point you to

arctic elk
young elbow
#

We had a research team internally that looked into implementing blockchains into our system (it wasn't auth so it could be different in your case). All the options they showed are terrible for auth... The point of blockchains is to verify as a group (subgroup or full) if the action is right -> meaning everybody would have access to the relevant data to process the action in question (list of all username/password)...
Even if you hash the password before logging in, you are allowing an external person to have the user/pass combo... This is not good. They can just bruteforce them one way or another.
There's as well another issue, blockchain has a performance cost...

Note: Im not a pro in blockchains, Im just relating what a presentation of a 6 month research on this subject taught me with some side knowledge. So there could be a way to do it without putting your data in the hands of an external actor, but, to me, it is alot of work for a database that will be slower than a normal sql database 🤷‍♂️

Hey guys, I'm a college student in a Java programming class and I need help with a problem.
The goal of the problem is to create a JFrame program that has a JButton that is disabled after 8 clicks, and then displays a message below it that says "That's enough!"
I managed to get the button to disable after 8 clicks, but I can't get the message to display.
This is my code here:

import javax.swing.*;
import java.awt.event.*;
public class JFrameDisableButton2 extends JFrame
implements ActionListener
{
final int SIZE = 180;
Container con = getContentPane();
JButton button = new JButton("Press Me");
JLabel label = new JLabel("");
int count = 0;
final int MAX = 8;
public JFrameDisableButton2()
{
super("Frame");
con.setLayout(new FlowLayout());
setSize(SIZE, SIZE);
setVisible(true);
con.add(button);
button.addActionListener(this);
}
@Override
public void actionPerformed(ActionEvent e)
{
    String indicator = "That's enough!";
    count++;
    if(count == MAX) {
        button.setEnabled(false);
        label.setText(indicator);
    }
}
public static void main(String[] args)
{
JFrameDisableButton2 frame =
new JFrameDisableButton2();
}
}

If someone can tell me what's wrong with it, that would be very helpful

That was a bit rude of me, I don't know you.
It's fine and good to program for money.
But there are many developers out there who just do not care what they're writing and how it reads and just copy-paste badly-formatted cargo-cult garbage into codebases and change it until it runs.

I write code like I would a paper, its meant for multiple people to read: me, the computer man, and usually other people (which includes me a few weeks from now). I write a rough draft, make some notes about its readability / how it could be simplified, then write it again. eventually you get good at writing that rough draft and making the notes in real time, but even just trying to write the same function 2 or 3 times in different ways each time can really help you figure out what works and reads best.

That's interesting to note. I'll remember that.
