    Project mention: ReactOS | | 2023-01-18

    No, Chrome only runs on newest amd64 Linux/Windows/Mac.

    For modern browser, there is compatible Firefox fork Mypal where older version works also on ReactOS. It can be installed on ReactOS 32bit from GUI package manager included in ReactOS, and I have also copied it to here:

    When I tried, newer versions of Mypal did not work on ReactOS 32bit.

    ReactOS 64bit is still more unstable, not much works on it.

    For older Windows versions like WinXP etc, that Microsoft does not support anymore, there are some replacements for Windows Update, like , some others are also listed at . When I tried it, it installed most updates, but not Windows Live Essentials and some other update.

  • SocketCluster

    Highly scalable realtime pub/sub and RPC framework

    Project mention: On the Unhappiness of Software Developers | | 2022-09-03

    This resonates with me 100%. Every bit of unhappiness I've felt in my career so far has been caused by a bad manager. The main issue for me has been the final point you mentioned about "Imposed artificial limitations" - I cannot tell you the number of times that I've been forced to use an inefficient tool or do something in a sub-optimal or downright incorrect way (knowing that it would have to be re-written later) by a bad manager... In some companies, it was a daily occurrence; that's why I never stayed at a single company for longer than 2 years. It's almost impossible to find a company that lets me implement things correctly.

    Thankfully, nobody could constrain me in my open source work. I (with the help of community members) built:

    - SocketCluster ( A distributed pub/sub framework.

    - Capitalisk ( A lightweight quantum-resistant blockchain which is less than 5K lines of code.

    - LDEX ( A deterministic decentralized exchange (DEX) which can work with many different blockchain protocols. It's less than 4K lines of code in total and only has 3 small third-party dependencies (including sub-dependencies).

    I've tried [Wampy](, [autobahn]( and neither work with my websocket. Wampy works if i patch it to use wamp.json but it's extra code I'd rather avoid, plus it doesn't have native typescript support.

  • kuzzle

    Project mention: What communication protocol/technology to use between IoT client and server? | | 2022-10-28

  • mirotalksfu

    🏆 WebRTC - SFU - Simple, Secure, Scalable Real-Time Video Conferences Up to 4k, compatible with all browsers and platforms.

    Project mention: Free Secure WebRTC P2P/SFU/C2C Video Calls, Screen Sharing, File Sharing, Chat and more. | | 2023-02-02

    I started the MiroTalk P2P & MiroTalk SFU projects during the pandemic period (about 1+ year ago), not knowing anything about the WebRTC. Making often the video conferences with my colleagues and not wanting to depend on Zoom, Teams, Google Meet... I decided to do some research about how it works and from there MiroTalk was born :) I Giving to everyone the chance to have its own instance of MiroTalk, which can be customized as you like and run in any cloud, vps, server. If you're just starting out, I suggest you take a look at the MiroTalk C2C (New) code, which can be a good starting point to understand how the architecture WebRTC Mesh (P2P) works. Later you can also study how the WebRTC SFU (Selective Forwarding Units - I recommend mediasoup which I personally love) or MCU (Multipoint Control Unit) architecture works. I wish you all the best!
