  1. ClemBot

    A Discord bot for server management with an emphasis on modularity and configuration. If you have an idea or a feature you would like to contribute feel free to open an issue and we as a community can begin discussion.

    I made a discord bot, https://github.com/ClemBotProject/ClemBot https://clembot.io Its not super interesting right now in terms of features but it has all the basics and a solid foundation. But we have some grand plans in the future and once those are realized then I might look into marketing it more.

  3. keyAlarm

    An alarm that prevents you from typing too much.

    https://github.com/TT-392/keyAlarm/tree/master

    It shouldn't be too difficult to write your own though, so, if anyone wants to do so, feel free to steal the idea.

  4. pdfcomments

    I made a simple tool to extract comments from PDFs with different severity levels. Mainly developed for my use marking up documents for review in an academic context, a need many academics have but I'm not sure how many others.

  5. phonk

    PHONK is a coding playground for new and old Android devices

    I made PHONK https://phonk.app

    It is a very easy-to-use self-contained JS framework for prototyping and making stuff with Android devices.

    You can access sensors, NFC, bluetooth, MQTT, websockets, or write a simple UI with a couple of lines of code.

  6. youtube2Anki

    Convert Youtube Transcripts to Anki cards

  7. storykey

    StoryKey is a proof of concept Brainwallet that converts an arbitrary string of data, such as a cryptocurrency private key, into an English paragraph intended for longterm human memory.

    StoryKey, an attempt at improving BIP39 brain wallet mnemonics. https://github.com/jcraigk/story_key

  8. pytkml

    Write tests for machine learning models

    I worked on (wouldn't say I completed) a testing framework for ML models, where you can specify a series of tests for a model to pass. The unique part is emphasizing support from the training data for the inferences you expect the model to make, i.e. checking that similar training data exists for some test cases and is influential in predicting them. It's pretty niche, and I don't explain it very well, but I remain convinced that with the right framing it represents a more rigorous way of making sure machine learning models are built and used "responsibly".

  9. sserver

    sserver is a simple headless server for hosting blog/static content and selling courses from your private github repository

    did not abandoned it since i am using for myself but didn't put any effort into marketing either other than mentioning it on hn few times https://github.com/newbeelearn/sserver . It's hHeadless server for hosting courses and associated blog/static content from private github repository.

  10. ViGEmClient

    Discontinued ViGEm Client SDK for feeder development.

    I didn't build it, but there's ViGEm for creating virtual Xbox 360 controllers: https://github.com/ViGEm/ViGEmClient

  11. jsynchronous

    Jsynchronous.js - Data synchronization for games and real-time web apps.

    A data-synchronization library for Node.js

    https://github.com/siriusastrebe/jsynchronous

    Ever get tired of sending API requests and JSON payloads? Wouldn't it be cool if data just synced between server and client?

    Jsynchronous lets you share deeply nested object/arrays between node.js and connected browsers – and any changes made to that variable.

  12. BlueRetro

    Discontinued Multiplayer Bluetooth controllers adapter for retro video game consoles & computers

    I entertained the idea to make and sell the hardware myself. But in the end I learned that's it's not something I'm interested to get into. What I really like is working on the software.

    In the end this pivoted into a more community driven project where multiple makers are selling various variations of the HW and giving me a cut of their profit to support the SW development.

    Recently I even got a Chinese company, notorious for selling "clone" of OSHW projects, to support the SW development as well via GitHub sponsor.

    I wrote a retrospective of last 3 years [2].

  13. gcloudrig

    Scripts to manage cloud gaming on Google Compute Engine.

    This seems to be a neat setup. I've found this script a couple days ago: https://github.com/gcloudrig/gcloudrig

    (haven't given it a try just yet but surely looking forward to)

  14. india-isin-data

  19. vgpu_unlock

    Unlock vGPU functionality for consumer grade GPUs.

    The vGPU feature can be unlocked for several Nvidia GPUs: https://github.com/DualCoder/vgpu_unlock

    I did not yet try it myself (maybe it doesn't even work anymore?), and it might not be an option for businesses.

  20. rps-scala

    Rock Paper Scissor online strategy game, implemented in Scala and Typescript

  21. syncplay

    Client/server to synchronize media playback on mpv/VLC/MPC-HC/MPC-BE on many computers

  22. kvm-switch

    Control hardware KVM/Matrix devices when your mouse moves to the edge of the screen (by timgws)

    The proverb 'necessity is the mother of invention' made me build a solution for sharing a keyboard and mouse between multiple devices.

    Synergy/Barrier is not horrible, but I find the latency a little painful.

    Ended up getting an industrial HDMI switch, with a KVM. Built a server in Go that connects to the serial port of all the devices.

    A companion client that runs on all the machines tells the server when the mouse moves to the edge of the screen, so the USB inputs can be switched to the correct computer. Basically, it allows you to have multiple computers connected, to multiple displays, sharing one keyboard and mouse. (You can define layouts on the server, so the displays can move around on the matrix HDMI switcher).
