Jabber vs. XMPP

XMPP is widely – and mabye better – known as Jabber. This was more or less the same until Cisco bought Jabber Inc and the trademark. You can read more about the story on the XMPP.org website. But is there still a Jabber around? Yes, it is! But Cisco Jabber is a whole infrastructure environment:… Continue reading Jabber vs. XMPP

Too much disk IO on sda in RAID10 setup – part 2

Some days ago I blogged about my issue with one of the disks in my server having a high utilization and latency. There have been several ideas and guesses what the reason might be, but I think I found the root cause today: SMART Self-test log structure revision number 1Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error#… Continue reading Too much disk IO on sda in RAID10 setup – part 2

Xen randomly crashing server – part 2

The second option would need to generate the Letsencrypt… Continue reading Letsencrypt: challenging challenges solved

I was following the Debian Wiki page on DNSSEC and related links. The linked howto on HowToForge is a little bit outdated as it targeted to Squeeze. I’ve learned in the meanwhile that… Continue reading Bind9 vs. PowerDNS

Progress of m68k port

A few weeks ago on Christmas Wouter and I blogged about the successful reinstallation of m68k buildds after a very long period of years of inactivity. This even got us mentioned on Slashdot. It’s been now roughly 3 weeks since then and we made some sort of progress:  Debian-ports.org shows now that we’re from 20%… Continue reading Progress of m68k port

INDECT: “Panopticon” von Tim Weskamp

Via Twitter rauschte heute die Empfehlung bei mir vorbei, mir zum Thema INDECT doch mal bitte schön den Film “Panopticon” von Tim Weskamp anzuschauen. Diese Empfehlung reiche ich gerne weiter:  Panopticon from Tim Weskamp on Vimeo. Bei INDECT handelt es sich um ein System, bei dem verschiedene Überwachungssysteme gekoppelt und zusammengeführt werden. Also zum Beispiel diverse Überwachungskamera,… Continue reading INDECT: “Panopticon” von Tim Weskamp
