Learn Programming

This community is aimed at two specific topics: - Support general programming questions, of any language, mainly for people beginning their journey in programming. - Give some advice on programming education or career.

should i go with Clojure or common Lisp? i'm looking for an intuitive language and the tooling is great. my background: Ruby programmer and i use neovim. my goal: AI development. do people really use Lisp family for AI dev tho?

I will frame the question in terms of a specific C# objective that I am working on right now but I imagine the question is a pretty general one related to the Dunning-Kruger effect, in a way - how do you know how to build an application when you don't know all the issues you are supposed to prevent?

I’m versed enough in SQL and RDBMS that I can put things in the third normal form with relative ease. But the meta seems to be NoSQL. Backends often don’t even provide a SQL interface.

Learning by doing is hard to beat when it comes to building software.

im trying to understand 'dynamic tables' [snowflake] and they kiiinda just sound like materialized views + automation on cache results?

Hi, I have this function that is supposed to upload a file stream to another page:

I've been stuck in this mindset where I can't think of any good website ideas, or game ideas, or anything really. I want to get out of this mindset by thinking, "What should I make?", or "What do I need to make?".

I know stuff like SDL and RayLib exists, but I already have my own X11 and Windows API stuff working, and otherwise those libraries like to obscure things from the user in the name of "ease of use", sometimes even missing features (force feedback and proper XInput are the ones that are often skimped out on for whatever reasons, and only SDL has them to my knowledge). While I'll implement libevdev eventually, it has the issue of needing access to the devices.

I not only have hard time finding tutorials, but even if I do, I have a hard time getting them to not crash, let alone working. I don't know what's the reason, but I have a suspicion that some of these are now AI generated, hence the issues of them not working or outright crashing.

For context, I am trying to do a save system for a game.

I just spent an hour searching for how I could have gotten an

I understand the basic principle but I have trouble determining what is the hard line separating responsibilities of a Repository or a Service. I'm mostly thinking in terms of c# .NET in the following example but I think the design pattern is kinda universal.

Besides some of the very, very obvious (don't copy/paste 100 lines of code, make it a function! Write comments for your future self who has forgotten this codebase 3 years from now!), I'm not sure how to write clean, efficient code that follows good practices.

So I have struggled with classes and objects but think I'm starting to get it...? As part of a short online class I made a program that asked a few multiple choice questions and returns a score. To do this there are a few parts.

Let's say I am making an app that has table Category and table User. Each user has their own set of categories they created for themselves. Category has its own Id identity that is auto-incremented in an sqlite db.

Just started as in, I'm about an hour into a 4 hour intro video. Seeing two basic ways of manipulating things and don't understand the difference.

I am really struggling to include proper testing practices into my code and would appreciate any advice on how to get going. I work in web dev so my I am interested in how to properly implement a suite of tests for websites and incorporate into it a CI/CD pipeline.

Hello, I would like to store these http headers in classes:

I get postman exports from students which I use to check their work. The authorisation of those requests now often contain hardcoded jwt tokens that are invalid by the time I get to checking them and I have to change every individual request with a global variable.

I'm trying to make minesweeper using rust and bevy, but it feels that my code is bloated (a lot of for loops, segments that seem to be repeating themselves, etc.)

When resizing an X11 window with OpenGL content, the image becomes garbled and certain parts of the window, usually at the parts that wasn't originally part of the initial framebuffer.

I'm writing a specification for a web app that will store sensitive user data, and the stakeholder asked that I consider a number of fairly standard security practices, but also including that the data be "encrypted at rest", i.e. so that if someone gains physical access to the hard disk at some later date the user data can't be retrieved.

I'm working on a little gui app that will eventually (hopefully) add a watermark to a photo. But right now I'm focused on just messing around with tkinter and trying to get some basic functionality down.

Does anyone else find javascript/electron-based code editors confusing? I can never understand the organization/hierarchies of menus, buttons, windows, tabs. All my time is spent hunting through the interface. My kingdom for a normal dialogue box!

Hi, I'm looking to open-source a small CLI application I wrote and I'm struggling with how to provide the built app since just providing the binary will not work. I had a friend test it and he had to compile from source due to glibc version differences.

Hi everyone,

Quick little confusion or even foot-gun I ran into (while working on the challenge I posed earlier).

hello guys. i am trying to match one or more digit from end of string

What are some tips and tricks and best practices with rust?

See learningrustandlemmy@lemmy.ml for future updates.

I want to learn how to build integrations, such as how to connect two systems made by different companies that have different structures.

I'm a seasoned programmer on Mac/Linux/iOS, and want to get into Windows application programming. Problem is, every time I try, Microsoft comes in a week later and discontinues the current framework in favor of something else. Because I need to use a C++ library, I started with C++/CX, just to be told C++/WinRT was the way to go etc.

A streamed reading club focused on rusts The Book and becoming reasonably good rust developers through community collaboration. If you're interested, please comment so we know this's something you'd like to join in on.

I realize this is a very *broad* question, so to help I'll mention that my primary experience with any programming language is Python. I've looked into C and C++ as well, but I haven't written much in them; in part because they're more involved, and in part because I get lost in the IDE weeds with'em (whether choosing an IDE or getting it configured to even get started tbh, but that's mostly a different topic).

I know how to implement basic oauth. My problem is that if I make a simple security filter like:

Noob question incoming, thanks in advance for any help with this!

I was exploring an obscure Linux distro when I noticed they're contact page had an IRC client. You can connect to the IRC via Matrix, but the people there prefer pure IRC.

I decided to go for kotlin as my first language because I had ideas for a mobile app. I quickly learned that android dev isn't the best starting point, and I'm not a fan of the lack of choice I have for editors with it. I only really know some basics, I used to know some javascript but forgot it

please make suggestions on the original post to help the original poster

Hey everyone, I'm looking for a studying mate so that we can compare each other's code etc. I have a course from work for JS (it's not mandatory) but I feel like if it's any attempt I tried in the past, without anyone to study with I will mostly end up neglecting in a few days.

Hello Lemmy,

I'm currently having trouble with the phone component I'm writing. To be extra vague about it, on my onChange, I'm using a function to move to the next text box. However, when I use my data handler function to raise the value to the parent, it doesn't work. In addition, by adding my data handler to the individual text boxes, it breaks my next Box function.

I am working on user authentication in Flask. I have my User class, which inherits from db.Model (SQLAlchemy) and UserMixins (flask-login):

Edit: TL;DR, a literal can't contain multiple children. The opening bracket that starts the literal must be closed at the end of the literal, with no other yuck appended.
