I fixed the error we were facing though, but the caption code we got from ChatGPT gave us a 429 error (rate-limited, ouch).
Concerning the server, one of the biggest issues was in the `handleSummary` function. I forgot to end the incoming request from Telegram. After sending a message to the Telegram API using Axios, I didn’t call `res.end("ok")`. That caused Telegram to keep hitting our webhook repeatedly, flooding the local server. 💀
Another problem was with parse_mode. I had it set to "text", but that’s not valid. Setting it to "Markdown" works though.
Was reading a book on compilers & interpreters and asked Copilot how Node.js works on the server since it uses JIT.
Turns out, Node relies entirely on the V8 engine, which first interprets your JS, then JIT-compiles the parts that run often (like your request handler). So even though it’s not ahead-of-time compiled, you still get crazy speed where it matters. This is probably also why it's faster than CPython.
Example: your handleRequest() function gets hit thousands of times? V8 spots that and compiles it to native code. Boom, optimized.
Also found out you can see what’s being JIT’d with: node --trace-opt --trace-deopt yourApp.js
Might make a quick vid breaking this down. It’s pretty sick how V8 does live tuning mid-server run.

Last night I decided to shake off some Rust—literally.
I built Cliano, a minimal command-line piano app in Rust. It maps WAV files to keypresses and plays them live in the terminal using only code, no GUI.
This was a fun challenge to stay sharp with Rust and remind myself why I started programming in the first place.
I even played “Mary Had a Little Lamb” using only terminal keypresses. Here’s a short demo I recorded of it:

A full YT video recap on how I built it is coming soon. Stay tuned.
Code is up on GitHub: github.com/Parado-xy/cliano

Ok, so… we didn’t finish everything today 😅

Anyway, I’ve pushed the updated code to GitHub if you want to check it out or follow along:
