Blogging is futile



Yet another Blosxom weblog from someone who promised himself to never start blogging - since blogging is futile.

Upcoming Hacker/FLOSS Events in Switzerland: Debian BSP, LPD, Hackerfunk 10th Anniversary, ZeTeCo

Wed, 03 May 2017 14:30:07 +0200

There are quite some events and dates ahead for hackers, makers, debianers and hackerfunk listeners:

Crowdfunding for ZeTeCo Camp in July Ends in Two Days!

You might have heard of the ZeTeCo Camp near Schaffhausen in July. If you want ot come or at least support that event, please contribute to their crowdfunding campaign.

They have more than 90% of their goal funded and there’s less only about two days left to reach their funding goal. If it doesn’t get funded in time, the event may be be on a knife edge.

Debian Bug Squashing Party in Zurich this Weekend

One week before the More-than-a-BSP at the Mozilla office in Paris there will also be a Debian Bug Squashing Party (BSP) in Zürich at the CCCZH Hackerspace “Röschtibach”. We’ll start on Friday, the 5th of May 2017 in the late afternoon, probably around 4pm or 5pm, and will end on Sunday, the 7th of May 2017 also in the late afternoon.

Please add yourself to the according section on the BSP’s wiki page if you want to join us to squash the hopefully not that many left over bugs in testing.

Unfortunately we didn’t notice two date clashes when we set the date for the BSP during the Annual General Meeting (AGM) of the Debian.ch Association earlier this year:

Linux Presentation Day this Saturday, 6th of May 2017

On the one hand there will be the Swiss Edition of the Linux Presentation Day (LPD) on Saturday, the 6th of May 2017 including the LPD in Zürich. The latter will take place in the same building as the BSP, just on a different floor: The BSP will be at floor B3 in the CCCZH Hackerspace and the LPD will be on the ground floor at Revamp-IT in the former ZKB foyer.

10 Years Hackerfunk: Show on 6th, Party on 13th of May 2017

And on the other hand, Venty’s and my (German dialect) radio show and podcast Hackerfunk will have it’s 10th anniversary show also on that Saturday. So I’ll vanish from BSP for a few hours on Saturday evening for broadcasting this very special Hackerfunk episode on Radio Radius.

But since Venty and me didn’t want to make yet another big event at “Röschtibach” on the same weekend, we’ll do the Hackerfunk 10th Anniversary Party one weekend later on Saturday the 13th of May 2017 also at the CCCZH Hackerspace “Röschtibach”. A separate announcement on https://www.hackerfunk.ch/ (also in the RSS feed there) will follow.




System Tray Icon to Monitor a Linux Software RAID Locally

Tue, 28 Mar 2017 04:09:16 +0200

About a year ago I bought a new workstation computer for myself at home. It’s a Tuxedo XUX_Cube which is advertised as gaming PC. But I ordered a slightly atypical non-gamer configuration:

  • As much RAM as possible (64 GB)
  • Intel i7 CPU, but the low power variant
  • Only with the onboard Intel graphics card. (No need for NVidia binary crap drivers.)
  • 2× Samsung 128 GB SSD for OS and $HOME plus 2× 3 TB WD Red disks for media storage; both pairs set up as RAID 1
  • Bitfenix Prodigy-M case in Orange. (Not available in Tuxedo Computer’s online shop, but they nevertheless ordered it for me. :-)

Of course the box runs Debian. To be more precise, it runs Debian Sid with sysvinit-core as init system and i3 as window manager. As I usually have no monitoring clients on my laptops and private workstations, I rather often felt the urge to do a cat /proc/mdstat on that box.

So at some point I wanted something like smart-notifier, but for Linux Software (MD) RAIDs. And since I found nothing, I did what Open Source guys usually do in such cases: I wrote it myself — of course in Perl — and called it systray-mdstat.

First I wondered about which build system would be most suitable for that task, but in the end I once again went with Dist::Zilla for the upstream build system and hence dh-dist-zilla for the Debian packaging.

Ideas for the actual implementation were taken from Wouter’s fdpowermon for the systray icon framework in Perl and Myon’s mdstat Xymon plugin for an already proven logic to parse /proc/mdstat. (Both, Wouter and Myon have stated in a GnuPG-signed e-mail that I copied less code than would validate their copyrights, so I was able to license it under a single license, namely GNU GPL version 3.)

As of now, systray-mdstat is also available as package in Debian Unstable. It won’t make it to Stretch as its first line of code has been written after the soft-freeze for Stretch was already in place.
