I went back to Sublime Text after trying VS Code for a few months.
VS Code is very nice, when it works. My main problems had to do with the extension ecosystem. It felt very chaotic: it was hard to figure out which ones to install to get the functionality I wanted. Updates to Python extensions sometimes caused instability, crashing the editor. And I found it difficult to set extension preferences: the UI tries to be slick but in practice it ends up being clunky and awkward. On top of that, there was an annoying bug on Linux, related to Electron, that prevented the Save dialog box from appearing properly, which... kind of sucks. https://github.com/electron/electron/issues/32857
Sublime is the perfect programmer's editor for dynamic languages like Python, and for general text editing. It's lightning fast. LSP is just enough to be helpful without getting in the way. Workspaces work the way I would expect. I prefer editing JSON files for preferences over navigating a complex GUI.
Best money I've ever spent on a license, and I'll happily renew just for maintenance updates, to be honest.

FlatBuffers, also developed by Google, is a highly optimized serialization library designed for scenarios where zero-copy deserialization is required.

It's a bit hard to do comparisons without going into threat models and all that _fun_ stuff :shrug:
For example, JS runs in almost every browser on earth too, yet it took V8 devs 2 years to find out that `Math.expm1()` could return -0.0 (https://chromium.googlesource.com/v8/v8.git/+/56f7dda67fdc97...). This is a cherry-picked example, and JS is clearly more complex than WASM, but still.
Just because stuff runs on a lot of devices doesn't mean it's more or less secure.
Linux runs on quite a few devices too, yet we still find bugs, people still don't ship updates to said bugs, yadda yadda yadda.
My point is just that lots of devs often skip the threat modeling and just think "I'll slap it in a WASM thingie an it'll be fine". Well good luck.

webview
Tiny cross-platform webview library for C/C++. Uses WebKit (GTK/Cocoa) and Edge WebView2 (Windows).
Project mention: Show HN: Vaev – A browser engine built from scratch (It renders google.com) | news.ycombinator.com | 2025-05-18What do you mean by that? WebView is just Chrome embedded inside of an Android app. Same thing already exists on Windows (Edge WebView2), macOS (WKWebView) and Linux (WebKitGTK). There's also a library that wraps all of them into a single interface:
https://github.com/webview/webview
The entire point of WebView is that it's a browser embedded inside of a different application, how do you expect it to be a "standalone project"?
-
perspective
A data visualization and analytics component, especially well-suited for large and/or streaming datasets.
Yes! This is the pro version, we also develop open source https://github.com/finos/perspective (which Prospective is substantially built on, with some customizations such as a wasm64 runtime).
-
nodegui
A library for building cross-platform native desktop applications with Node.js and CSS 🚀. React NodeGui : https://react.nodegui.org and Vue NodeGui: https://vue.nodegui.org
-
Project mention: Electrobun: Cross-platform desktop applications written in TypeScript | news.ycombinator.com | 2024-11-20
So is it a yet another webview-based framework like NeutralinoJS (https://neutralino.js.org), Electrino (https://github.com/pojala/electrino) or DeskGap (https://deskgap.com)? What's their advantage apart from using Bun instead of Node?
For relly lightweight cross-platform desktop apps better use a non-webview-based native framework like Qt, GTK, wxWidgets or even recently released FLTK 1.4.

Launched in 2021 with the promise of enhancing the developer workflow, quick-lint-js positions itself as a complementary tool to ESLint. It is designed for “real-time speed”, offering rapid feedback within your code editor without latency. Another goal of the tool is zero-config, so it’s opinionated. The tool is aimed at a particular target group.

There are some really interesting parts around sending commands to WASM applications in there, I would encourage you to explore those yourself, along with the super interesting article by Cornelius Diekmann on porting DOOM to WASM I mentioned earlier.

PythonMonkey
A Mozilla SpiderMonkey JavaScript engine embedded into the Python VM, using the Python engine to provide the JS host environment.
Project mention: How to engineering a JavaScript to Python migration? | news.ycombinator.com | 2025-03-14Check out PythonMonkey [1], it's an actively maintained project which embeds the SpiderMonkey JS engine inside a Python library. It reuses the same memory buffers whenever possible and allows for pretty impressive interop like executing functions back and forth [2].
At my last job we used PythonMonkey to port our complex distributed computing JS Library to Python enabling us to reuse all the code and keep almost all the performance.
