All Linux lovers, and supporters of open source code and free software, in the Kanto area (or anywhere else) are invited to attend the next Tokyo Linux Users Group meeting. Membership is open to anyone. There are currently no membership dues or entrance fees.

TLUG meetings are traditionally small and unstructured (VERY CASUAL). Most of the benefit of the meeting comes from chatting with other Linux users and having informal discussions.

As a general rule, the Technical Meetings are held on the 2nd Saturday of odd-numbered months and the Nomikai Meetings are usually held on the 2nd Friday of even-numbered months. There are, of course, exceptions to this rule, so it is best to keep an eye on the mailing list, or check back here for date/venue changes as the date approaches.

Technical Meeting


July 14, 2018 (Saturday)




We are looking for a location at or near Akihabara. If you have somewhere we could use or know someone who does please get in contact with Edward Middleton.


"Introduction to Snakemake" - by Raymond Wan

Snakemake is a workflow definition language similar to Make that is gradually becoming popular in the field of bioinformatics. Even so, there is nothing about Snakemake that limits its use to bioinformatics. Unlike Make, the Snakemake language is Python-based. In this talk, I will introduce Snakemake and provide examples of how it can be used for data analysis.

"VDO, transparent Linux compression/de-duplication layer" by Christian Horn

  • Use cases: where can VDO help?
  • VDO setup and configuration
  • How is VDO influencing read/write performance?
  • How much storage space can I save for my use cases?

"Linux on the Nintendo Switch" - by Christian Horn

  • Why is Linux@nintendo-switch interesting at all, what is required to get it running?
  • What works, what works not, on various distros? What is the Linux installation looking like?
  • Demo (will be hard to show it nicely, as HDMI output is not working and the internal screen is small)

"Introduction to Matrix, a platform for unified, decentralised, secure communication" - by Alexey Rusakov

The talk will discuss Matrix (, an open network for real-time communications. I will describe its main features (servers federation, end-to-end encryption, bridging) and show what sets Matrix apart from many other messengers. I'll further talk about how one can use Matrix to bridge communities across other networks, both proprietary and open, including IRC, Telegram and Slack. An overview of the ecosystem and a short demo will conclude the talk.


After the technical meeting we will move on to the Oktober Fest at Hibiya park, where Benjamin Kowarsch has informed us he will be serving at the stall for "Weltenburger, the world's oldest abbey brewery, in operation since at least AD 1035 in Bavaria."

Other items on the agenda
  1. Introduction of new members
  2. News about Linux/Open Source, general announcements, Q&A
  3. Auction (bring any gear that would would like to donate to TLUG)
