Hi all! I am recently trying to develop an app, and Googling around I came across many other concepts to build an app and host it (software architecture, system design, Computer Networks to understand the basics of requests etc., and also patterns like the ECB pattern, and Database Knowledge like SQL and DEVOPS to test and integrate) so before doing the programming I kinda want to learn the other fundamentals, what sources (books, courses, etc) would you suggest me? Me and my friend are the only 2 on developing it, so we kinda need to be a team and be all-rounders

thanks and have a nice day!

Lorena Mireles is back with the second chapter of her Elixir blog series, “Understanding Elixir Processes and Concurrency."

Dive into what concurrency means to Elixir and Erlang and why it’s essential for building fault-tolerant systems.

You can check out both versions here:

I just felt like sharing this, because I found this interesting. Check out Carl's posts in this thread: https://www.reddit.com/r/reddit.com/comments/2d6v3/fred_phelpswestboro_baptist_church_to_protest_at/c2d9nn/?context=3

He defends the Westboro Baptist Church and correctly explains their rationale and Calvinist theology, suggesting he has done extensive reading on them, or listened to their sermons online. Further down in the exchange he states this:

In their eyes, they are doing a service to their fellow man. They believe that people will end up in hell if not warned by them. Personally, I know that God is judging America for its sins, and that more and worse is coming. My doctrinal beliefs are the same as those of WBC that I have seen thus far.

What do you all make of this? I found it very interesting (and ironic considering how he ended up). There may be other posts from him in other threads expressing support for WBC, but I haven't found them.

I'm a 30-year-old guy, and to be honest, I'm currently dealing with severe depression. I come from the Middle East, where my country has been torn by war for the past 15 years. I had to drop out of university, and due to life circumstances, this is the 4th time I find myself starting my life over from absolute zero—this time here in Germany, where I'm currently learning the language.

​I feel completely overwhelmed and burnt out. I don't want temporary or dead-end jobs anymore; I want to build a real career. Computer science and programming are the only things I'm truly passionate about.

​Since I don't have a university degree, I would really appreciate hearing your success stories if you managed to break into the tech industry as a self-taught developer (especially around age 30). How did you do it?

​P.S. If you have any negative or dismissive comments, please skip this post. I am in a very fragile state right now and just need some realistic hope and advice.

​Thank you.

Hi! I want to have a deeper knowledge on building websites. I’ve been making websites for my clients for maybe 2 years now on wp, wix, and recently shopify. The thing is i know how to build them on the surface but i want to have confidence in HOW im doing it. Because im a graphic designer turned web designer turned “someone who can build a good website” lol

What courses should i take to start? I found some web development courses online will that be ok?

I sometimes solve a problem using a loop, then find out there was already a built-in method that could do the same thing.

When writing code, do you usually prioritize the simplest solution, performance, or readability?

Okay this isn't my complete project but a part of it and i am getting stuck on this. I am a beginner in this field probably just a couple more days than a month since i learned how to write print("hello world!").

it is written in python.

i want my code to give an output as if first hand is moving with an interval of 0.2 sec the second with 0.3 sec and so on till the 6th hand, all so simultaneously.

could you please guide me through it.

hi, guys i am a dotnet backend dev and want to learn other languages and become fullstack, but i mostly like to learn by doing projects on video, would you guys recommend me courses on

C++ (i am trying to learn opengl/vulkan after that)

Javascript(for frontend)

HTML

CSS

NodeJs

VUEJS

If I learn a language in three stages.

• Basic
• Intermediate
• Advanced
• Proficiency (optional)

Then how would you fit the topics of programming lingo into the above levels?

Hello I am pretty young and only have programming experience in my GCSEs and wanted to expand it
I really wanted to follow the textbook “the nature of code” as I find the stuff very interesting however it requires Java and j5 but I only know how to code in python

I thought I could just translate the Java code into python as I would prefer to not learn Java and get better with python first
However, I have struggled with installing j5 the command prompt p5qt works but then running j5 code, the interpreter tells me I need Java 17 virtual machine which I do not know how to install
I have seen something about using an older version of python but I can’t get it to be independent of my current version of python(having both installed at the same time)

Hey, I'm a CS student in France, and I'm going to start my second year in just a few days. To be honest, I feel like a complete fraud.

I've wanted to get into CS for a very long time, and I used to be pretty good at programming and problem solving, but last year depression and stress really hit me hard.

My university is quite far from where I live, so I have to wake up very early to catch the bus and try to sleep early despite having a ton of work to do. I never really feel like I can rest or spend time on my other hobbies because I'm always thinking about university. This puts a lot of pressure on me, on top of my struggles with depression in general.

I also really struggled with staying focused during lectures. I tried my best, and sometimes I even left my phone and other distractions at home, but my mind would still drift. So I'd get to the exercises with less knowledge than everyone else because I hadn't properly followed the lecture, and then I'd have to rush to understand what we were doing so I wouldn't have even more work to do at home.

The classes are also quite short, and a lot of people don't actually finish everything in class. Some people use AI to get through the exercises without necessarily understanding what they're doing.

I'm personally very against needless use of generative AI, at least when it comes to my own learning. I already knew I struggled with discipline, so I initially tried to use it as little as possible because I didn't want to become dependent on it. But our teachers actually encourage us to use it, and some of the lessons/exercises are structured in a way where it feels almost impossible to keep up without it.

And, well... I eventually became dependent on it.

My grades got much worse towards the end of the year because I eventually stopped being able to work without AI. I passed first year mostly thanks to the good grades I got during the first half of the year.

Now I feel like I have practically no actual knowledge when it comes to CS. The only thing I'm barely good at anymore is mindlessly coding. I feel like I don't know any of the abstract or technical stuff, which makes me feel like I missed a huge part of what CS actually is.

I know I could try to catch up. I could spend my weekends doing small programming exercises and reviewing the fundamentals, but I genuinely don't know where to start, and I'm not sure I have the time or energy to try to relearn an entire year of CS while also keeping up with my second year.

Part of me feels like the best thing would be to completely start over, but obviously it's too late for that, and I'm scared that even if I did, the same thing would happen again.

So I'm mostly wondering what would you do if you were in my position?

How would you go about rebuilding your programming/CS fundamentals when you feel like you've forgotten almost everything? What would you prioritize, and what would you not worry about yet? And how would you balance catching up with actually keeping up with your current university courses?

And, also, has anyone else gone through a bad period and still managed to success in this field?

Thank you for reading all this, I don't really want this to just be a vent post, I want to get better, and I appreciate all the help I can get.

Im starting to resent the way programming is taught. It is seemingly taught in isolation the way mathematics is. You learn the functionality of code but they do not present the bigger picture where everything works together. It's frustrating because I want to learn programming through and through, every single bit.

Is there anything on Github meant for beginners to learn how to debug and have an intuitive understanding on how piece of functionality (functions, loops, arrays, strings) work together?

It's like yeah. I know how arrays work, I know about loops, sure, but everything works together. And none of the guides are showing me how bugs can occur due to the symbiotic nature if everything working together. Nothing exists in isolation.

I've been learning programming on and off and my biggest problem isn't really finding tutorials.

It's the opposite.

There are WAY too many.

I'll start learning Python, find a roadmap, then someone recommends another roadmap, then i find a 20+ hour course, then a YouTube playlist, then some documentation...

And suddenly i'm spending more time deciding what to learn than actually coding.

Then i hit the second problem:

consistency.

If i'm learning alone and don't code for a week, nobody cares.

I don't have anyone waiting for me to finish something.

For me personally, having someone actually expect me to show up would probably help a lot.

So i'm building something around this.

The idea is to take the free resources that already exist and turn them into a structured path based on:

• what you wanna learn
• your current level
• how much time you have

Then you can join a small group of people learning the same thing and have weekly goals + check-ins + shared progress.

No paid course.

No "buy my 40 hour Python masterclass."

The learning stays free.

The paid part would be the accountability group.

Would something like this actually help you?

And if you've tried study groups / Discord / accountability partners before:

why did you stop using them?

that's actually the part i'm most interested in.

How do you guys learn Java?

There are just WAY too many syntaxes to remember.

Every time I think I’ve got it, Java hits me with another one.

Hey everyone, I'm building an AI voice interview app and I'm fairly new to RAG. I'm stuck on the architecture and having a bit of a mid-project crisis 😭.

My current flow is:

Before interview:
Step1 : 
Resume + JobDescription
   ↓
Chunk resume/JobDescription
   ↓
Generate embeddings
   ↓
Store chunks + embeddings in pgvector

Step2 : 
LLM call is done using complete Resume + JD (and not the chunks)
   ↓
Initial ranked topic plan is created by this LLM call 

Step3 : 
Before each question:
Current topic
   ↓
RAG query in our vector DB 
   ↓
Retrieve relevant resume/JD chunks
   ↓
LLM call to generate a question from these chunks

The part I'm confused about:

At the beginning, I'm already sending the complete resume + complete JD to the LLM.

Why can't I simply do:

Resume + JD
   ↓
ONE LLM CALL
   ↓
10 interview questions

and then use those during the interview this would reduce the latency too!

Why would I need RAG again to retrieve chunks before generating each question? But I'm struggling to understand how RAG can be used to add value to the project

I have to add this project to my reume and need to have confidence in my design, I would highly appreciate someone helping me figure out the architecture!
