Show HN: Tracemap – run and visualize traceroutes from probes around the world 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 appears to jump across continents, the geolocation is probably wrong. • Suboptimal routing is sometimes much easier to notice visually than by just looking at latency numbers. • Even with really good databases like IPinfo, IP geolocation is still not perfect, so parts of the path may occasionally be misleading. Huge credit to the teams behind Globalping and IPinfo — Globalping for the measurement infrastructure and IPinfo for the geolocation data. Feedback welcome. https://tracemap.dev/ March 5, 2026 at 11:40PM

Show HN: Guish – A GUI for constructing and executing Unix pipelines https://ift.tt/HrXz5ub

Show HN: Guish – A GUI for constructing and executing Unix pipelines guish is a dynamic data pipeline UI that allows users to visually construct and execute complex command-line pipelines. It provides an intuitive interface for chaining together various Unix commands and custom plugins, making it easier to build and understand data processing workflows. It also features optional LLM support for updating pipelines with a natural language interface. https://ift.tt/2lsA0r5 August 2, 2024 at 10:00PM

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints https://ift.tt/2yet5m3

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints Hey HN, we’re Naman and Rushil, founders of PillarPlus ( https://ift.tt/3dHyOBg ). We build software to automate the creation of construction blueprints. Specifically, our software generates engineering blueprints for air conditioning, ducting, fire, electrical, and plumbing services over the floor plan of the building. MEP (Mechanical, Electrical, and Plumbing) designs are a set of 15 technical drawings. We got started in India and are currently operating there, but MEP is standard enough that the software can apply to Western markets also, given that we have incorporated international building codes. Architects and contractors hire consultants, who still design the building manually. Complete dependence on human effort results in a process that is slow, error-prone and unreliable. Also, the number of consultants is limited resulting in higher fees, long delivery times and difficulty accessing the services. ...
