  • InfluxDB - Access the most powerful time series database as a service

  • megabasterd

    Yet another unofficial (and ugly) cross-platform MEGA downloader/uploader/streaming suite.

    megabasterd, a desktop app used for downloading files hosted on The project is quite popular but barely anyone except for the original author understands the code. There is nothing good in it, it's just a big mess. But it kind of works and people use it. I'm pretty sure you can find most software bad practices in there.

  • jmurmel

    A standalone or embeddable JVM based interpreter/ compiler for Murmel, a single-namespace Lisp dialect inspired by Common Lisp

    To my defense, I have started my Lisp compiler/ interpreter mostly for recreational purposes to do the exact opposite of what the checkstyle nazis at my $job demand.

  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.

  • javakdb

    Using Java with kdb+

    The Java client for the kdb+ database. It's a single file, see for yourself:

  • jsch

    Mirror of JSch from JCraft. (by is)
