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.

[AskJS] Do you use JavaScript on Microcontrollers? Which engine / interpreter?

This year in Servo: over 1000 pull requests and beyond
I thought it would be a fun weird project to make Servo work with MS' abandoned JavaScript engine:
https://github.com/chakra-core/ChakraCore
Of course it is written in C++ and you'd probably want a pure Rust browser. But it is sad seeing that fairly complete open source JIT JavaScript engine sit and rot.

Have you deployed Microsoft Todo to end users? How did you deploy it?
As a Linux user, I very much think Microsoft should have continued Trident and Chakra. Apple also should have continued releasing Safari for Windows. Our web QA setup was entirely built around Macs back then, but it was great to be able to test sites with Safari on Windows, and to have another responsive browser on Win32.

The Javascript Engine
Edge was initially using Chakra but has been rebuilt using Chromium and the V8 engine.

I've found the source code to be quite readable too - albeit from a bug-finding perspective, not a strictly pedagogical one.

Exploring React Native’s new architecture
Furthermore, the new architecture decouples the JavaScript interface from the engine, enabling the use of other JavaScript engines such as Hermes, V8, or Chakra.

Enumerating and analyzing 40 non-V8 JavaScript implementations
I am astonished at the omission of ChakraCore, open sourced by Microsoft but sadly abandoned by them after they switched Edge to Chromium: https://github.com/chakra-core/ChakraCore. But it looks like it’s still chugging along as a community effort rather than being completely abandoned.
