What it does

NetHang is a web-based network quality simulation built on Linux. It is designed for simulating those annoying real-world network issues—like latency, packet loss, jitter or bandwidth limitation.

NetHang is a web-based network quality simulation tool that allows you to create and manage network paths between LAN and WAN interfaces. Ideal for use with software routers on Linux platform. It focuses on simulating weak network (poor network) conditions, with built-in scenario models(Edge, 3G, 4G, Wi-Fi, Starlink, etc.) and combinations of parameters such as packet loss, delay, jitter, and bandwidth limitation, etc. It helps you simulate various network conditions and monitor their effects on traffic. In simple terms, NetHang needs to run on a Linux-based software router . If you already have such a software router device or are familiar with how to set up the environment, it will be…from nethang.org

  • Netrinos – A keep it simple Mesh VPN for small teamsDec 2025 · netrinos.com · ▲93

    I'm the founder at Netrinos. I built a WireGuard-based mesh VPN because remote access has always been a pain. After years of SSH tunnels, IPsec headaches, and the ssh log horror movie, I wanted something simpler: install, sign in, get work done. Netrinos creates a LAN-like overlay network across your devices. Connections are direct P2P via WireGuard, with no central server routing traffic. Each device gets a stable IP and DNS name (pc.you.netrinos.com). When direct connections fail, they fall back to a relay server that's still encrypted end-to-end. We can't see your traffic. The most…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
