@natalininhas Eu não vejo problema, mas acho que a pessoa menstruada tem que falar antes, não tem muita diferença, só sujar mais e aumenta o risco de IST, mas provável que tinha proteção então só suja mais mesmo

By the way, eBPF can be used in a lot of interesting and unusual ways, including stuff most devs don't even think about

Everyone knows it for networking and observability. But that's like using a supercar just to go to the grocery store

You can hook into any kernel event - syscalls, tracepoints, kprobes - without touching kernel code. Zero recompilation. Just vibe and attach

Security folks use it to build runtime threat detection that catches exploits as they happen. Not after. During

You can rewrite packets mid-flight. Like, actually change the destination IP before the kernel even blinks. That's how Cilium replaces iptables entirely - and it's blazing fast

Profiling CPU flamegraphs in prod with near-zero overhead? Yeah that's eBPF. bpftrace one-liners are genuinely magic for this

There's even people using it for canary deploys - shifting traffic at kernel level, no sidecar proxy needed. Insane

Game companies use it to detect cheat engine hooks. It's basically watching the watchers

By the way, Katran - Meta's L4 load balancer built on eBPF + XDP - is genuinely wild in terms of performance (and XDP does 26M pps per core on commodity hardware, do the math)

So, if you're doing anything serious with Linux and not looking at eBPF, you're leaving massive power on the table, really

If you are a CS student, don’t just build CRUD apps.

Build systems like this instead:

1. Tiny search engine
- Input: a folder of text files or scraped web pages.
- You build a parser + an inverted index (word → list of documents + positions) + simple ranking (TF-IDF or frequency).
- Why it’s powerful: touches parsing, indexing, memory vs disk trade-offs, and query performance

2. Toy scheduler
- Simulate an OS scheduler with processes (arrival time + duration).
- Implement FIFO, round robin, and shortest-job-first.
- Visualize Gantt chart + calculate waiting/turnaround time.
- Why it’s powerful: shows understanding of concurrency, fairness, and performance

3. Key-value store with caching
- Think “mini Redis”: GET/SET over TCP or HTTP.
- Use an in-memory map + optional write-through to disk.
- Add LRU/LFU cache + eviction on memory limit.
- Why it’s powerful: covers serialization, networking, memory constraints, cache design.

4. Rate limiter
- Service that limits requests per user/IP/API key.
- Implement token bucket, leaky bucket, or sliding window.
- Store counters in memory or your own KV store.
- Why it’s powerful: real backend problem time windows, atomic updates, distributed correctness

5. Simple load balancer
- Reverse proxy that forwards requests to multiple servers.
- Use round-robin or least-connections.
- Add health checks + remove failed servers.
- Why it’s powerful: teaches systems thinking, networking, availability, resilience.

Just found this great tutorial on writing your own Linux system call in C.
If you’ve ever wondered how read, write, or fork actually work under the hood this is for you.

@func25 Interesting to note as go is not preemptive, this select gives back the "CPU/machine" thread to runtime.
