NTP diag tool, as is Ping for ICMP

What it does

Rusty Klock Inspection Kit - NTP / NTS Querying tool - aguacero7/rkik

Think dig , but for time sources. No daemon, no root, no config to touch. rkik queries NTP and NTS servers and tells you what they say: offset, RTT, stratum, authentication status. One shot, stateless, done. nix shell nixpkgs#rkik DEB / RPM / tar.gz: grab the latest from GitHub Releases . # Debian / Ubuntu sudo apt install ./rkik_2.2.0-1_amd64.deb # Fedora / RHEL / Alma / Rocky sudo dnf install rkik-2.2.0-1.x86_64.rpm # Basic NTP probe rkik pool.ntp.org # NTS — cryptographically authenticated rkik --nts time.cloudflare.com # Compare a few servers side by side rkik --compare pool.ntp.org time.google.com time.cloudflare.com # Plugin output for Nagios / Centreon / Zabbix rkik pool.ntp.org…from github.com

In the maker’s words, at launch

I’ve released rkik v1.10, a lean Rust tool to inspect NTP servers, compare offsets/RTTs, and optionally perform a one-shot system clock sync on Unix. Repo: https://github.com/aguacero7/rkik For those who dont know what it does: - Probe a single NTP server or compare multiple in one shot…

  Sping – An HTTP/TCP latency tool that's easy on the eye2025 · dseltzer.gitlab.io · ▲178

  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. (Available at…

  Whirlwind – Async concurrent hashmap for Rust2024 · github.com · ▲140

  Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

  Talanoa▲346

  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…

  I spent 6 years building a ridiculous wooden pixel display▲1,145

  I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

  I was curious about spherical helix, ended up making this visualization▲865

  I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
