    :electron: Build cross-platform desktop apps with JavaScript, HTML, and CSS

  • Project mention: Release Radar • February 2024 Edition | dev.to | 2024-02-29

    The team at Electron have been faithfully shipping new releases almost every single month. I think they had Christmas off 🤔. This popular framework has developers writing cross-platform desktop applications using JavaScript, HTML and CSS. The latest update depreciates some process events, and added new modules, APIs, methods, and more. Read into all the changes in the Electron release notes. This month, Electron also introduced a new formal RFC process.

  • Project mention: Boehm Garbage Collector | news.ycombinator.com | 2024-01-21


    Due to the nature of web engine workloads migrating objects to being GC'd isn't performance negative (as most people would expect). With care it can often end up performance positive.

    There are a few tricks that Oilpan can apply. Concurrent tracing helps a lot (e.g. instead of incrementing/decrementing refs, you can trace on a different thread), in addition when destructing objects, the destructors typically become trivial meaning the object can just be dropped from memory. Both these free up main thread time. (The tradeoff with concurrent tracing is that you need atomic barriers when assigning pointers which needs care).

    This is on top of the safey improvements you gain from being GC'd vs. smart pointers, etc.

    One major tradeoff that UAF bugs become more difficult to fix, as you are just accessing objects which "should" be dead.

  • 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: Brig: A user interface toolkit for Node.js, which is based on Qt for rendering | news.ycombinator.com | 2024-01-20

    This looks like it hasn't been maintained in years but there's a modern equivalent in NodeGUI [1] which also has React/Svelte/Vue implementations. Unfortunately it requires a custom build of Node that merges the libuv and Qt6 event loops so YMMV.

    It actually inspired me to write my own implementation with Svelte on top of QuickJS and Qt Widgets but the task of wrapping the entire Qt6 API in Rust proved to be intractable once I found out that most methods weren't marked Q_INVOKABLE and thus couldn't be called via reflection (requiring manual wrapping). Providing a `Document.createElement` API that created Qt Widgets with working attributes and event handling worked surprisingly well though!

  • neutralinojs

    Portable and lightweight cross-platform desktop application development framework

  • Project mention: Show HN: Pywebview 5 | news.ycombinator.com | 2024-03-13

    We tried using pywebview for a cross-platform desktop app when it was version 3.x and some of the features were limited, especially when it came to systray interactions. Will have to try it out again. In the end, for that specific project, we ended up settling on NeutralinoJS. Wails was another big contender but due to limited GoLang resources in-house, we decided not to use it. Reference: https://neutralino.js.org/

  • Project mention: Is there any game where you can design your own weapons/vehicles? | /r/computerwargames | 2023-12-10

    It is more an RTS than a 'classical' wargame, but you could do it in Warzone 2100. It is old for now (but it was very fun in 2000s). It could be fun for you today. There is a free and open source version : https://wz2100.net/ .

  • Project mention: An ES5-compliant JavaScript interpreter, written in Java | news.ycombinator.com | 2024-03-09

    I would guess that depends on the licensing context in which it will be running, since Rhino is MPLv2 <https://github.com/mozilla/rhino/blob/Rhino1_7_14_Release/LI...> and OP's repo is MIT whereas Graal is UPLv1 <https://github.com/oracle/graaljs/blob/graal-23.1.2/LICENSE>. GitHub's license gizmo claims it is OSI/FSF approved, but Oracle gonna Oracle and they for sure have more lawyers than you do

  • duckdb-wasm

    WebAssembly version of DuckDB

  • Project mention: Parquet-WASM: Rust-based WebAssembly bindings to read and write Parquet data | news.ycombinator.com | 2024-04-22

    i think duckdb-wasm is closer to 6MB over wire, but ~36MB once decompressed. (see net panel when loading https://shell.duckdb.org/)

    the decompressed size should be okay since it's not the same as parsing and JITing 36MB of JS.
