Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Trippy 0.9.0 Release
As a reminder, Trippy combines the functionality of traceroute and ping and is designed to assist with the analysis of networking issues. You can think of it as a modern, cross platform, Rust based version of tools such as mtr, with a bunch of advanced features and a fancy TUI.

Show HN: How did YOUR computer reach my server?
Cool project! Two suggestions, one serious, one frivolous:
- I wonder if you could get more accurate results by using TCP or UDP instead of ICMP. I think traditional traceroute has an option to use UDP, mtr [1] can use TCP or UDP, and tcptraceroute [2] can use TCP.
- This would be a perfect fit for some Talking Heads references. "And you may ask yourself, well, how did I get here?" [3]

Internet goes out every day at 4:15pm
Run mtr, or whatever the Windows equivalent might be, and leave it running shortly before 4:15pm, and see where the traffic stops when the Internet shuts off.

Troubleshooting Issues
Consider using MTR (software) towards the actual end-point of the SIP connection to get a combination of traceroute and ping which will be much more revealing. This will also allow you to quickly identify if the problem is local to your equipment or somewhere along the path. Consider allowing her to join a Google Conference from Teams to determine if it is provider related. Yes, port mirroring and wire shark is the gold standard and will display the "answer" on your screen quickly but it requires skills to know what to analyze, look at and how to interpret the data.

Tmux over ssh freezes faster then ssh session timeout
Have you tried something like mtr to check for connection issues? I would recommand the view you get when hitting d twice after starting it (with the colored graph for latencies).

What's everyone working on this week (17/2022)?
Continuing to build trippy; a network diagnostic tool inspired by mtr. There is still a long way to go but it is getting closer to feature parity with mtr.

Show HN: Happy Pi day with this PWA to cut 100k Pi digits offline
It uses service workers to cache static files, by the time it opens up you already free to be offline, try toggle network switch to verify.
It has download link at bottom of the about page ([accdoo.app/about]) which you could then self host it by dropping into any static hosting services.
btw, the Pi feature was by-product from the original App but I won't expand here, if you'd like to learn more, please checkout its two Show HN post (39115559 and 39138957) previously.

Can you make your own JavaScript by implementing ECMAScript standard?
I think QuickJS, written in C, is a user-"friendly" starting point for implementing ECMA-262. Documentation QuickJS Javascript Engine.

New QuickJS Release
There is a readme on the project's main page: https://bellard.org/quickjs/
The newsworthy bit here is that the activity seemed to have stalled for year or two and now Fabrice pushed a few fixes and made a new release.

GitHub
Just to demonstrate GitHub repositories do not necessarily reflect upon a programmers' body of work, Fabrice Bellard has one (1) repository published on GitHub, quickjs. Compare the list of work on Bellard's home page https://bellard.org/.

WinterJS
> I am still confused, it's a JavaScript runtime intended to be deployed to JavaScript/Wasm runtimes?
Seemingly.
> Why does a JavaScript runtime need a JavaScript runtime?
Because if you want to create a Service Worker server for CloudFlare Workers and other JavaScript/Wasm runtimes, that's the only option for doing that AFAIK.
FWIW, this isn't a new idea. For example, Figma uses QuickJS (https://bellard.org/quickjs/) for their plug-in runtime: https://www.figma.com/blog/an-update-on-plugin-security/
