Products that do what Tracemap – run and visualize traceroutes from probes around the world does

Hi HN, I thought it would be fun to plot a traceroute on a map to visually see the path packets take. I know this idea has been done before, but I still wanted to scratch that itch. The first version just let you paste in a traceroute and it would plot the hops on a map. Later I discovered Globalping (https://globalping.io), which allows you to run traceroutes and MTRs from probes around the world, so I integrated that into the tool. From playing around with it, I noticed a few interesting things: • It's very easy to spot incorrect IP geolocation. If a hop shows 1–2 ms latency but…

    This nifty tool plots the traceroute results and shows you the RTT as well as the distance travelled by the packets! Supports MTR, flyingroutes and of course, traceroute. The existing solutions were too limited so I made that. Let me know if you have any feedback

    I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.

    Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.

    I've been working on GeoTraceroute for a while and just shipped v2.3 with submarine cable inference. A few things that might interest HN: - 320 community-contributed nodes across 50 countries, all volunteer-run - Three views: 3D globe with day/night rendering, 2D map, and a topological mode that infers submarine cable routing - The submarine cable inference is the part I find most interesting. Since cable routers don't respond to ICMP, the underwater segments are invisible to standard traceroute. The tool detects ocean crossings by geolocation delta between consecutive hops, then infers…

    Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

    This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

    I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch. The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be…

    Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

    Over the past week I built a project to let people self-host an entire maps stack so they don't have to send data to the big G. Right now it includes a base map, geocoder and directions server. Currently only bicycle directions are supported, and I'm only hosting tiles for Seattle because I'm unemployed and can't afford to host data for the whole planet. Check it out! https://maps.ellenhp.me/ https://github.com/ellenhp/headway Ultimately I'd like to really focus on transit routing (not implemented) but I'll probably throw a driving mode in there too.

    I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to…

    I built this over the weekend. Any feedback is appreciated. Please note you will need a WebGL enabled browser. Thank you for checking it out. --UPDATE-- HN Traffic is strangling earthbit. There is sporadic downtime due to the web services I am using, if no transactions appear after a few seconds, then please try again in an hour.

    Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

    I wrote a minimal traceroute(1) clone that leans on asynchrony to reduce the time spent tracing a route. Underneath, it uses ICMP to do its job. The plan is to add support for UDP tracing and a path maximum transmission unit discovery mechanism. Comments and suggestions are welcome!

    Technologies used: Leaflet (frontend) Turf (Geojson generation and Voronoi generation) I noticed that my neighborhood is all Lawsons, so I got the location of all Conbinis and ran some basic analysis to see if these pockets of brand territory are common. I haven't worked much with web frontends before, so feedback is welcomed. I also have some ideas to maybe expand upon, like making the territory calculations based on streets and other geographical features rather than just beeline distance. The site isn't tested too much on mobile yet, but should be ok. Currently the frontend code and…

    Hey! I'm a solo developer having fun learning Go. I have a side hustle and wanted to implement currency localization. I could use existing IP databases, but hosting on serverless is slow. So I built my own. I was surprised how fun it can be to use Go, and it's fast. Thankfully, Go's speed makes up for my dodgy code. Anyway, I'd love to get some feedback on my website/API. After a few weeks of testing and losing money on ads, I'm confident it's very reliable. This isn't a promo. It's basicly free (30k lookups/month), so there's no need to pay. Any advice or tips on how to grow and…
