    LMAX Disruptor

    LMAX Disruptor

    High performance inter-thread messaging library

    LMAX aims to be the fastest trading platform in the world. Clearly, in order to achieve this we needed to do something special to achieve very low-latency and high-throughput with our Java platform. Performance testing showed that using queues to pass data between stages of the system was introducing latency, so we focused on optimising this area. The Disruptor is the result of our research and testing. We found that cache misses at the CPU-level, and locks requiring kernel arbitration are both extremely costly, so we created a framework which has "mechanical sympathy" for the hardware it’s running on, and that’s lock-free. This is not a specialist solution, it’s not designed to work only for a financial application. The Disruptor is a general-purpose mechanism for solving a difficult problem in concurrent programming. It works in a different way to more conventional approaches, so you use it a little differently than you might be used to.

    Goofy

    Goofy

    Desktop client for Facebook Messenger

    Goofy is a macOS client for Facebook Messenger. But unlike most other clients, it does not use any of Facebook's APIs, but is basically a single-site browser that injects a little CSS and JS into messenger.com to make it a little more app-like. Feel free to create issues on this repo for feature requests of any kind. However, some features may not be possible due to the way this application is working. Also, I don't want this to be a feature-bloated monster, but a slick and small app. Depending on the number of contributors and the progress of this app, I will schedule releases from time to time, which will then be distributed on goofyapp.com. To debug, there's a VSCode launch.json that can be used to debug the Electron app. To debug the Facebook JavaScript changes you'll need to use the Chrome Web Inspector.

    NXCord

    NXCord

    Unofficial discord client for the Nintendo Switch

    Discord's TOS forbids the use of third-party clients, thus use at your own risk! Download the latest build from Releases. Extract it to the root of the SD card you use for your switch. You do need to reboot your system, otherwise, the sysmodule won't start running. After rebooting you can open NXCord in the homebrew menu and you will see a login screen if it's your first time using it. Selfbotting means that you are using a third-party client to access discord with a user account. It's against the TOS of discord, thus not recommended. I've been using a user account for testing for months already and haven't been banned yet. Might be safe, but I am not responsible for any bans!

    tmi.js

    tmi.js

    Javascript library for the Twitch Messaging Interface

    Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false.
