Built a realtime multiplayer tile-capture game to understand WebSockets + Redis Pub/Sub

Simple game shared grid, you claim tiles, others can steal them back. Everyone has a cooldown between captures and limited steals. Last person standing with the most tiles wins. That's it.

Built it entirely to understand things I kept reading about but never actually felt — goroutines and channels for managing concurrent WebSocket connections, Redis Pub/Sub for cross-instance sync, stateless backend design, and clean layered architecture. Each WebSocket client runs in its own goroutine and a central hub uses channels to fan out broadcast messages without race conditions. Hosting frontend and backend separately made CORS and WebSocket upgrade issues very real very fast.

Question regarding branch and placements

Hey I don't have much idea but just for knowledge (as I am looking for colleges now) how does lower branch affect your placement and all? Like if you are doing btech from lower branch but also side hustling just like cs students so will you get such placement offers like them?

Anyone got a job despite having no experience till 3rd year?

I am currently in my 3rd year of college and I feel really anxious about placements and my future. I do not have any internship experience, I have never participated in hackathons, and I was not part of any clubs in college either.

Now I will be moving into 4th year soon and seeing everyone around me with achievements and experience is making me nervous. I feel like I wasted a lot of time and I am scared that it is too late to improve my profile and get a decent job.

Is anyone else in a similar situation or was in this situation before? Is it still realistically possible to build skills, projects, and get a job from this point onward? I would really appreciate honest advice and experiences because I am feeling very lost right now.

best python yt cource free

Hey guys,

So I'm a 2nd year B.Tech student (4th sem) and I've been thinking about getting into Data Analysis for a while now. Finally decided to actually start and not just keep postponing it lol.

I want to learn Python from scratch properly. Not just watch random videos here and there but like an actual structured course that doesn't waste my time jumping between topics.

A few things:

Hindi would be preferred honestly, easier to understand concepts deeply

Free only, can't afford paid stuff rn

Certificate doesn't matter to me at all, but if the course offers one then that's a bonus I guess

I want something that will actually take me towards Data Analysis, pandas, NumPy, that kind of stuff, not just stop at basic Python

I'm not looking for the "most popular" one, I'm looking for the one that's actually worth sitting through. If you've done it yourself and felt like it was genuinely useful, please suggest that one.

Any help appreciated 🙏

And also is data science diying/ currently I'm doing dsa in Java and haven't touched to anything yet except frontend development

Built a project using codex, for open source peeps

so i basically built issue-pilot, it explores the repo you give it, checks the issues and categorizes them. and also checks the comment history if any issue has been already assigned or not. and then u can accordingly work on the non assigned issue, it was a real problem i faced so i decided to add this to my workflow.

Would love some feedback.

Guide please

I’ve solved around 140 DSA leetcode problems and I genuinely enjoy logical problem solving. Recently I started frontend development, but while learning CSS I realized I don’t enjoy UI/UX or design-oriented work.

I’m more interested in logic-heavy or problem-solving-based development rather than designing interfaces.

Could you guide me on: • what career paths fit this interest, • whether I should continue frontend basics anyway, • and what skills I should focus on instead?

How would someone go about coding something like this? Where would the even begin? I'm guessing C# is the best programming language to use here.
