Ask Lemmy

Harvard CS50 on YouTube might be a good start. Teaches python and you can then pivot to another language from there.

Realistically, you should still find a project that you want to do and use that as the basis of your learning, as that will influence your language of choice,. I'd start with either python or powershell stuff to get going, as both are general purpose, multiplatform languages that can do a lot and are moderately forgiving with syntax and stuff.

Past that, find a project that interests you, break down what needs done, and learn those steps individually. It's not as cohesive as a hand holding hello world style tutorial, but I found I learned so much better if I had a need for the knowledge instead of just learning for it's own sake.

In my case, I picked powershell as I'm a windows admin. Since I'm a data hoarder as well, I chose a video conversion pipeline to convert all of my movies into a consistent file format. Part of the requirements are to find all files with an extension that isn't my standard (concepts: file listing, filtering, working with objects) and then execute an external program to convert the files (concepts: command line execution, state management, error handling, looping), validate the conversion completed successfully (concepts: reading file content, filtering/regex), moving the files to a new location or replacing the file with the new one and backing up the original (concepts: file management), and log file retention and cleanup. As I developed my script, I also began learning to properly "function-ize" my code to make things more readable/usable, and eventually started moving functions into a module to better modularize my code.

A decade later and I'm currently in the middle of a couple of projects using powershell to make and call API functions to automate business services at work.

Also, before starting writing code: learn to break down things small things.

I learned using python.

I've yet to find anything that would have been a better place to start, and the concepts you pick up coding almost anything are extremely transferable.

A small project is good because it doesn't just teach you the basics, it makes you apply what you learn to actually do stuff.

I write little python scripts to do various things all the time. Most recently I made one that automatically posts the next comic strip to !moomin@sopuli.xyz.

My recommendation would be to come up with something like that, then start figuring out how to do each step of accomplishing the task you want the code to do, then putting it all together. Look things up a lot, use print() often, and trial and error your way to the goal.

You could also read guides or watch videos, but personally I learn WAY faster by just doing.

Reading the code, making changes based on how I think something should work, then being proven right/wrong also seems to give me a better understanding than just following instructions.

To add to the list, Codingame.com

It wouldn't be the first thing to try. Get the basics down on your own machine/environment. Try this for something additional.

CodinGame gives you the IDE and build environment in your browser, so it's for learning/practicing/testing coding knowledge without building/deploying locally, or worrying about UI/persistence/networking etc.

It's filled with coding puzzles and competitions. I started where they give you animated scenarios (to look like part of a game or engine), and you contribute a small, missing unit of code to complete the challenge.

You can choose from 25 languages, they encourage unit-testing, and there are global coding competitions and company outreach to top coders. I don't wanna say they gamified it.. but they did.

But once you're comfortable with those, CodinGame lets you practice different concepts & algorithms without having to come up with the bigger systems around them.

I've loved it for getting back to coding after a while, tinkering with certain concepts, or trying other languages.

I'm not affiliated with it. Just loved the idea & execution. Except for Mars Lander III challenge. That can get @#$&ed.

One thing that has not been mentioned that will make a big difference: join an online community.

When you get stuck or you're confused and need to ask a question, you need to have a place you can reliably go to for that. You will also be able to see others go through their learning journey which will encourage you to keep going.

Someone mentioned The Odin Project already, but they have a very big and wholesome community.

My specialty is web development, but the concepts of programming is pretty universal. Feel free to DM me personally if you want some help.

I've been going through The Odin Project for full stack web development. It's been great and is completely free.

I would advise against using Chat GPT or any other LLM; they "hallucinate" and can give you wrong information.

Like others have said it depends on the field you want to code for and language choice. The field might inform your language choice.

I'd highly recommend python as your first if you're just looking to get stuck in. It'll teach good fundamentals, it doesn't have a steep learning curve and it has a very wide set of applications plus loads of community support. This website is what I recommend to anyone wanting to learn python: https://futurecoder.io/

Good luck!

Step 1 is determining what kinds of projects you want to make and selecting a language and/or libraries that will help you do that. Eg. if you want to code for the web, there's JS. Then you can follow tutorials, and/or jump into making small projects.

I know you've heard it, but seriously, the biggedst hurdle to learning programming is having a solution looking for a problem. You can learn all kinds of stuff in the abstract, but your brain will either handwave over it or bounce off, if it can't contextualise the knowledge into a problem-solving tool.

A source of small but genuine needs is the scarcest resource.

I know the world has moved on to big cosy high-level languages that let you think semantically about everything but honestly I'm still a big fan of starting with C; it is something of an austere discipline, but it gives you a boots-on-the-ground view of the problems you're working with, and I think that really helps shape your understanding of what you're dealing with.

(you could do a fair bit worse than the game 'human resource machine' for a slightly gentler introduction, then pick up some exercises in C, then move to python or similar - it will let you appreciate the cosy high-level stuff, and have a better feel for why you're doing stuff)

I always recommend https://automatetheboringstuff.com/ as it helps teach you python basics, as well as learning some coding fundamentals. Its free at the website, while offering a book version you can purchase. I have been coding in python professionally for 5 years, but I started with these tutorials (after doing a non-python coding bootcamp that focused on full stack web development)

IT guy here, I don't really program, but I do write scripts in Powershell and Bash from time to time.

I mostly learn by doing, so I have a task that I need to write a script to accomplish.

One script I often use is a tool I made to ping devices in a network range.

This breaks down into several smaller steps.

1. Define the start IP address
2. Define the stop IP address
3. Issue a ping command
4. Repeat the ping command for every adress in the defined range.
5. Output the data
6. Colour code the data
7. Make every IP address ending with a 0 be colourded in the output.

Each step is fairly simple to find out how to solve, together they make a good script to solve the initial issue.

Start my picking what you want to do with programming. Then do a couple of simple challenges in any language like advent of code and such in python just to get your feet wet and solve some problems.

After that you should have the main building blocks and then you scale up into making a "thingy" sized project. I personally liked making games with progression like.

1. Text adventure
2. Tic tac toe
3. Another text adventure but with battles and hit points.
4. Tetris

Then you can start learning separation of code into modules like "This is the game and this is just how it's shown" which applies to pretty much every application with a user interface.

After that you have enough skill to learn anything and you can go about learning a specific skill or technology that you want to work with and you'll be at a skill level of a junior programmer.

Advancing beyond that I'd recommend reading a couple of books (crazy I know) that go over best practices and why they exist. You use those guidelines and get better at working with larger amount of code and then you get to mid level. During this time you should also basic rules of thumb on how long each thing takes to run, both algorithm complexity and how http requests are usually the bottleneck.

For senior level you'll need to gain a lot of experience and become a library of solutions and bug knowledge while also having a good grasp of tradeoffs. You'll need to know when to insulate yourself from change and when it's overkill to deliver the code in a timely manner while not sacrificing tomorrow.

It's very hard to skip any step in my opinion but reading a couple of books really helped me advance through the junior phase quickly just by knowing what solutions are out there. Books are not as valuable when you don't have experience since it'll stick 10x better if you encountered the problem described in the book.

To get started just pick anything and get your feet wet. Good luck!

Pick a language to start. If you want to automate CAD, maybe it has an existing scripting language built-in?

Learn the basics from the documentation. Look at the examples. Learn how to search for specific answers.

Finally, practice a lot. Most of the challenge is breaking a problem down into discrete steps (your algorithm), which can be written in pseudo-code. The implementation of that algorithm may look different depending on what the target language is, or what library/tools you can leverage within that language.

https://codingbat.com/ if you choose Java or Python

https://www.freecodecamp.org/

https://adventofcode.com/ has easy-to-challenging problems suitable for any language

Not sure why nobody mentioned it, but use GPT or whatever you like to create code for you and explain everything. It is like talking to someone with some experience. Not everything is perfectly correct etc. if you get into more complicated stuff but you will certainly learn a lot and fast. The learning curve got a lot flatter with these tools.

Learning a programming language , is pretty simple (didnt say it was easy)....its memorization. Maybe less so now with the advent of things like Copilot/AI assistants.

Understanding what you're trying to accomplish is possibly the harder part. I would rephrase your statement: "I want to learn how to build an application". For this you can butter toast...with instructions.

Pretend there are two people, one is the instructor and one is the toaster/butterer. There is a wall between them so one cant see what the other is doing and the end result is buttered toast. There are a couple resources; bread, butter, knife, toaster, plate.

1st attempt the instructor says: Pick up bread, put it in toaster, take out bread and put on butter. Result: Untoasted bread, butter on hands

2nd attempt the instructor says: Pick up bread, put in toaster, push switch down to toast, take out bread and use knife to put on butter. Result: Loaf of untoasted (did you check if toaster is plugged in?)bread with butter on both sides sitting on the counter (remember the plate?).

See how specific you have to be about certain things? I would call this functional programming. Object oriented program takes it a bit farther in that the toaster is now classified with things like; browness level, electricity/plug state, slice/bay current occupancy, toast switch etc.

Code combat

Check out https://roadmap.sh/ for a guideline on your set goal!

There's lots of options for starter projects, but I'd say a great place to start is making yourself a personal web page in html, css, and js. you can host it for free on github, neocities, or nekoweb, and its really cool to make something you can show off.

Even if you don't stick with html as your primary language, the web is so ubiquitous now that you'll want to know it eventually!

I personally really liked https://learnjavascript.online/ when I was just getting started with JS. I use the knowledge from that course like every day at work now. The same guy also made a general programming course for beginners, I bet it's good as well: https://learnprogramming.online/

What I especially liked about the course was that you got little assignments between each lesson, that you could just solve in their web IDE. So there's no fiddling around to set up an external IDE. Big big plus for me, I hate setting up stuff like that

CodeAcademy.com used to have great free classes, but idk if they're free now. The language you choose depends on what you want to do. Share more details about what sort of stuff you want to code. You develop your coding skills through use, and practice. Pick a project slightly above your skill level and do it. You'll learn a lot during that project and retain the information much more than if you were just going through a tutorial. Then pick another project slightly above your new skill level and do that too. Repeat for 20 years.

Just search for tutorials, and then follow the steps in them.

I'd say install linux first as it will make things easier as python is built in and ts just a better OS all around.

As for getting started you can use youtube Or some free books such as

https://automatetheboringstuff.com/ https://inventwithpython.com/

And more here https://pythonbooks.org/free-books/

After a few videos and a book you will get the hang of it and get more confident in your abilities. Then do a project of your own

There are other languages but python will allow you to make progress fast and you can branch out to a different language later of if you like.

What type of idea do you have? You can "generally" use any of the popular languages, but some are better suited to rapid/beginner use for certain applications

I too would recommend that you start with something small that you want to build and google the best language for it and a guide.
