  • GitHub repo franc

    Natural language detection

    Project mention: Reasons Why JavaScript is Awesome | | 2021-10-04

    Franc is a JavaScript package that allows you to detect the language of a given text. I have included a small program to illustrate how it works. You can provide the program with a paragraph of text, and it will use the franc library to try to detect its language. Note that the functionality doesn't work great when provided with a shorter text.

  • GitHub repo yomichan

    Japanese pop-up dictionary extension for Chrome and Firefox.

    Project mention: Yomichad - Japanese pop-up dictionary for qutebrowser | | 2022-01-14

    I really love qutebrowser, but what initially kept me from using it as my main browser was the lack of a Japanese pop-up dictionary userscript in the vein of yomichan, 10ten or rikaikun. That's why I wrote my own one, called yomichad. If you are interested, you can find more information in the repository. I hope it will be of help to others as well!

    Project mention: Show HN: Pronounce – practice while you browse for any language | | 2021-11-23
  • GitHub repo profane-words

    A very long list of English profanity.

    Project mention: Threading and Mutable data objects for a profanity filter in Python | | 2021-12-08

    the list is too large for it to sensibly fit in primary memory (CPU cache -- not RAM) you can design you data structure to help the CPU/computer prefetch or at least build your list more sensibly. Consider a radix tree if you need higher performance but if you are running single-threaded, you should ignore the locks and just go wild! here is a list of profanities: zacanger/profane-words

    Try LLG-MP! It has a nice OpenSubtitles integration. Go to Search at the top, click on Subtitles, then search for your favorite movie or TV show episode. Then click Download. Wait a bit, then it should show you a list of all relevant subtitles. Click on your favorite, and play the video. It should show the subtitles too! Not too big on customization yet, but it can basically play these subtitles with a cool OpenSubtitles integration right out of the box.

  • GitHub repo langua

    A suite of language tools

    Project mention: The Ultimate Conlanging Software [Thought/Idea] | | 2021-06-08

    One software covering all of those things would be really difficult, but I've got an open source project that covers (or is intended to cover) several of these items (focusing more on the language creation parts than the other aspects). I’d always welcome contributors! It’s definitely a side project for me, so development is fairly slow, as I have time to work on it.
