Today was the first day of Linux Conf Au 2009 [1]. KaiGai Kohei was unable to attend the conference and give a database mini-conf presentation about his work on Security Enhanced PostgreSQL [2], so I gave the presentation in his place. It was a fairly difficult presentation and required that I learn a lot about […]

I have just had a need to install packages from Debian-Multimedia.org to correctly play .3gp files from my mobile phone (the stock Mplayer in Debian would not play the sound). As part of getting this to work in a way that I like I rebuilt some packages so that shared objects would not demand an […] There is currently a discussion on the Debian-security mailing list about how to protect data which came from an encrypted file. I was going to skip that one until someone summoned me by mentioning SE Linux. The issue which was raised is that data from an encrypted file can be read from /dev/mem (for all […] One thing that concerns me about using any online service is the security.

The email address […] One ongoing problem with TCP networking is the combination of RPC services and port based services on the same host. If you have an RPC service that uses a port less than 1024 then typically it will start at 1023 and try lower ports until it finds one that works. A problem that I have […] Currently we have a problem with the Debian list server and Gmail. Gmail signs all mail that it sends with both DKIM and DomainKeys (DomainKeys has been obsoleted by DKIM so most mail servers implement only one of the two standards although apart from space there is no reason not to use both). The Debian […] I was reading an interesting post about predicting the results of the invasion of Iraq [1]. One of the points made was that the author rejected every statement by a known liar (which includes all the world leaders who wanted the invasion). So basically regarding every statement by a known liar as potentially a lie […] I’ve just installed Eran Sandler’s OpenID Delegation Plugin [1]. This means that I can now use my blog URL for OpenID authentication. I’ve also included the plugin in my WordPress repository (which among other things has the latest version of WordPress). One thing that I consider to be a bug in Eran’s plugin is the […] |
