Re: Oracle bought ksplice … and apparently the source was pulled
I contacted one of the good people from ksplice (I’ve got an active subscription) and got pointed to oss.oracle.com/ksplice/software/ Unfortunately the access to a distributed version control is gone for good, it seems.

Installing php5 on Ubuntu requires apache2?
When I wanted to install lighttpd today I added php5 to the apt-get install. But then it would tell me that apache2 and numerous other packages would also get installed. Turns out that instead of php5 I actually wanted php5-cgi. … Continue reading
Little annoyance
Lately in Ubuntu 10.04 I got upon login two times the output about the number of packages available to be updated. One of them always outdated. I have long tried to find the reason and finally managed to. The problem … Continue reading

mydumper – nice alternative for mysqldump

XMPP S2S with Google and no TLS?
I’m running an ejabberd instance and it’s configured to use TLS in S2S (server to server) communications. It works perfectly fine with jabber.ccc.de, but Google’s server does not seem to like TLS. Very awkward. First I thought it may be … Continue reading
