Ask HN: How to learn how to develop real time applications?

Sat, 05/23/2026 - 5:53pm

I am a C++ programmer and I want to learn how to develop real-time programs. It looks like it's a "lost art" these days.I think we all use such programs every day to one degree or another. For example, if you work with a network, then you probably use wireshark. If you work with audio, then you probably use something from this field. What do I mean by real-time apps? These are applications where we have a part that creates data (or a data stream, with high frequency) and a part that processes it (or gui part, if we somehow process it). I would like to focus specifically on network applications. I'll say right away that I've already read Richard Stevens book[1], but it doesn't seem to be enough to develop applications of this level.

Show HN: World Cup 2026 free family and friends prediction platform

Sat, 05/23/2026 - 5:39pm

Hi all,

I was testing Cursor for the past week and a half and I decided to build a quick platform for my family and friends to make a little prediction tournament for the World Cup 2026.

My goal was to have the easiest possible setup for elderly relatives, no sign ups, mobile friendly, $0 budget for hosting platform.

I doubt this will get popular but in the odd case of happening just letting you know I'm using free vercel and neon db tiers :D In case you wonder why is slow and/or down.

I'd love to get some feedback on the scoring system, do you think I can improve it and make it more competitive?

Tech stack & development: - vibe coded with mainly Opus 4.7 with Cursor - Neon free tier 0.5 GB db - vercel free tier - github actions - for games - I've loaded the whole tournament and found API - football-data.org cron for pulling the results (free API key for 10 request per min) enough for what we have here

- React - Next.js - translated to 4 languages English/German/Spanish and of course Bulgarian.

Thanks, Anton
