In plain words
This is a traceroute tool written in pure C without external dependencies. It traces the network path from a user's computer to a destination by showing each hop along the route. The implementation prioritizes speed and simplicity by avoiding library dependencies, making it lightweight and easy to compile. It's designed for network administrators and developers who need a standalone, efficient way to diagnose network connectivity and routing issues.

From the sources
Fast, dependency-free traceroute in pure C. Minimal syscalls, clear output, significantly faster than standard traceroute. Fastrace is designed for speed. By using non-blocking sockets, batch I/O, concurrent probing, and optimized syscalls, it completes traces significantly faster than the standard traceroute utility. fastrace completes the trace ~20x faster while providing richer output including load-balanced path detection. sudo ./fastrace google.com fastrace 1.0.0 Tracing route to google.com (142.250.180.174) Maximum hops: 30, Probes per hop: 3, Protocol: UDP TTL │ IP Address (RTT ms) Hostname ────┼──────────────────────────────────────────────────────────────── 1 │ → 192.168.1.1 ( 6.15…from github.com

The original inspiration comes from being tired of having a specific site (and finding it!!) that serves my needs for a single purpose. Straight forward tools, no fuss. The objective is to be fully in-browser, no login and if possible without contacting a remote server.

CodeTracer – A time-traveling debugger implemented in Nim and Rust2025 · github.com · ▲334Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
