Past Meetings

Raul Suarez will present user-oriented file synchronization. He writes:

In the past we have heard about rsync and own cloud and other mechanisms
that, among other things, can be used to keep data synchronized across devices.

I work on several computers at home. Recently I found that I had to
remember in which computer I left the latest version of certain documents.

I went from computer to computer until I decided I needed a way to
synchronize them.
I compared and evaluated several tools and finally came to the one that
worked better for me. In this presentation I will go through the different tools I investigated
so you can decide which one works for you.

Khalid Baheyeldin will relate his adventures replacing a defective drive on his laptop, while keeping all the data from his old drive. There are a few tricks involved, such as getting hibernate to work.

Update: Khalid has made his presentation slides available here:

We will follow this up with a roundtable discussion on techniques and best practices for supporting new (and possibly nontechnical) Linux users, especially in a world with cloud services.

Andrew Cant will present a gentle introduction to the Git version control system.

UPDATE: You can access Andrew's demo slides here: https://github.com/acant/git-cli-presentation-2015.

Chris Irwin will follow up his successful April meeting on btrfs by covering his experiences with backups and btrfs snapshots.

John Kerr snapped up a Raspberry Pi 2 board when they went on sale, and he will show off his toy and discuss its suitability as a "real computer".

The second half of the meeting will consist of audience questions and audience answers to those questions. Bring your questions! Bring your answers!

Marc Paré is involved with the LibreOffice development community, and he will discuss the project. He is interested in growing a local developer community around LibreOffice.

Jotham Apaloo will show us how he uses systemd-timers in place of cron jobs on his machine.

John Kerr ran into a scheduling conflict for May, so he will present the Raspberry Pi in June.

Chris Irwin will relate his experiences with btrfs, a next-generation file system. He will explore an end-user perspective of the goals, benefits and problems (both solved and created) of this new filesystem.

UPDATE: Here are the slides from Chris's presentation: 2015-04-13-btrfs.pdf

Nathan Fish will discuss the importance of choosing the right license for software you write or modify, and some guidelines for doing so.

Khalid Baheyeldin will share some of his adventures flashing an Acer A500 tablet with OmniROM.

Tim Laurence will tell us about AppArmor. He writes:

AppArmor promises to provide easy to use application security.

Just in time to miss tax season, this month's meeting will feature two presentations on free-software accounting systems:

- John Kerr and/or Brent Clements will present GnuCash, a graphical double-entry bookkeeping system.

- For those who find GUIs too intimidating, Chris Frey will present ledger, a commandline accounting system that processes text files of your earnings and expenses.

Update: Chris has made his sample ledger file available: 2014-05-demo-ldg.txt (you can rename this to 2014-05-demo.ldg to make it a proper Ledger file).

OpenSCAD is a script-driven, free software 3D CAD modeller that is widely used in the maker and 3D-printing community. Marius Kintel (who happens to be the lead developer of the project) will tell us about OpenSCAD and demonstrate its use.
