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.

Gadgetbridge is an Android application for your smart watch and other devices
The Bangle.js 2 is an excellent device. As a former Pebble user, this is the first device that I consider an adequate replacement for my Pebble (which by now has a diminished battery life and corroded charging contacts).
Here is my impression of the Bangle.js 2:
- Battery: Lasts about 3 weeks on a charge, constantly connected to my phone, when the watch is used to display notifications and alarms. This is a major advantage over Apple Watches and Android/Wear OS watches.
- Display and buttons: The 1.3" 8-color transflective display is comparable to the Pebble Time series' 64-color transflective display. The display is always on, and the backlight activation is highly configurable. The Bangle.js 2 has a touchscreen and 1 button, while Pebble watches have no touchscreen and 3 buttons.
- Software: Runs on the completely free and open source Espruino JavaScript interpreter,[1] which was my main motivation for purchasing this device. There are currently 336 apps in the web-based Bangle.js app loader (app store), including utilites and clocks (watch faces), all of which are FOSS. The bootloader and firmware can be updated directly from the app loader. On Android, there is a distribution of Gadgetbridge (built from the same code base as Gadgetbridge) with internet access enabled that integrates the Bangle.js app loader into Gadgetbridge, which makes it very easy to use the watch.[2]
- Build: Built on the same device body as the SMA Q3.[3] The casing is plastic, and the watch is compatible with standard 20 mm watch straps. The IP67 water/dust resistance makes the watch usable for sports.
Overall, I highly recommend the Pebble.js 2 watch, which is the best FOSS-focused watch I have found to date.

Can the PineTime Watch stream music without a phone? (Onboard music storage)
There are subsets of JS for embedded device e.g. Espruino https://github.com/espruino/Espruino for BangleJS https://shop.espruino.com/banglejs also with 4MB or JerryScript https://jerryscript.net

Boa JavaScript Engine v0.17 released
Yeah, pretty much. I'm not sure if we're gonna need to implement Static Shapes first but at least we need to make it possible to separate codeblocks from contexts for this to be feasible.

Official /r/rust "Who's Hiring" thread for job-seekers and job-offerers [Rust 1.67]
Hi, I'm looking for full time work and I'm interested in roles related to compilers, developer tools and systems. I'm a college senior(graduating on May, 2023) and have been working as an [IOS Developer](https://www.cyengagement.org/) for the past two years. At University, I took a compilers class where I learnt to use LLVM and MLIR to compile programs to various architectures. In Oct. 2022, I was selected to attend the [Programming Language Implementation Summer School](https://pliss.org/2022/) where I got to learn about compiler implementation and language tools from leading researchers around the world. Recently, I have been contributing to [Boa](https://github.com/boa-dev/boa), an embeddable Javascript engine written in Rust, by fixing issues and implementing features to improve conformance with ECMAScript specification. Aside from working on compilers, I have volunteered at conferences like ICFP'21 and PLDI'22 to familiarize myself with latest research in the field of compilers. You can find more information about me and my work in my [blog](https://veera.app) and Github [profile](https://github.com/veera-sivarajan). Thank you for your time and consideration.

Adding a JavaScript interpreter to your Rust project
I already use it in my project to run some parts of the youtube js player. I must say it was broken on one version of the player because of a generated regex inside (more on the issue), but definitely recommending.

Dune: A new JavaScript and TypeScript runtime built in Rust
I would be curious how much effort it would be to swap boa for V8 to have an all Rust runtime :) If it's not meant to be a production-ready project anyways.

Implementing a safe garbage collector in Rust
Although you probably could use it for something else, Boa[1] is a good demonstration of this (it uses the GC crate, but the same principle probably applies).
