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 […]

There is a lot of discussion and speculation about The Singularity. The term seems to be defined by Ray Kurzweil’s book “The Singularity Is Near” [1] which focuses on a near-future technological singularity defined by significant increases in medical science (life extension and methods to increase mental capacity) and an accelerating rate of scientific advance. […] One of the most interesting new technologies that has come out recently is Cloud Computing, the most popular instance seems to be the Amazon EC2 (Elastic Cloud Computing). I think it would be good if there were some open alternatives to EC2. Amazon charges $0.10 per compute hour for a virtual machine that has one […] A Linux Users Group like most volunteer organisations will often have a small portion of the membership making most of the contributions. I believe that every LUG has many people who would like to contribute but don’t know how, here are some suggestions for what you can do. Firstly offer talks. Many people seem to […] In my previous post about DKIM [1] I forgot to mention one critical item, how to get Postfix to actually talk to the DKIM milter. This wasn’t a bad thing because it turned out that I hadn’t got it right. I had configured the DKIM milter on the same line as the milters for ClamAV […] I have just installed Domain Key Identified Mail (DKIM) [1] on my mail server. In summary the purpose is to allow public-key signing of all mail that goes out from your domain so that the recipient can verify it’s authenticity (and optionally reject forgeries). It also means that you can verify inbound mail. A weakness […] It’s not easy to choose a laptop, and part of the problem is that most people don’t seem to start from the use of the laptop. I believe that the following four categories cover the vast majority of the modern use of mobile computers. PDA [1] – can be held in one hand and generally […] It seems to be a common idea by non-bloggers that the comment they enter on a blog is somehow special and should be taken seriously by the author of the blog (everyone is a legend in their own mind). In a recent discussion one anonymous commentator seemed offended that I didn’t take his comments seriously […] I have previously written about the execmod permission check in SE Linux [1] and in a post about SE Linux on the desktop I linked to some bug reports about it [2] (which probably won’t be fixed in Debian). One thing I didn’t mention is the proof of the implication of this. When running a […] |
