RAM is the new Disk [1] – interesting post about using a distributed network of servers with RAM for main storage. The concept is that RAM on another machine can be accessed faster than local disk and that disk performance for contiguous IO has been increasing steadily at a greater rate than random seek performance. […]

Never Trust a DRM Vendor

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 […]

My Prediction for the iPhone

I have previously written about how I refused an offer of a free iPhone [1] (largely due to it’s closed architecture). The first Google Android phone has just been announced, the TechCrunch review is interesting – while the built-in keyboard is a nice feature the main thing that stands out is the open platform [2]. […]

OpenID Delegation

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 […]

Now Using OpenID

When this post goes live I will have had OpenID running on my blog for 24 hours.

My first attempt to do so was not successful. The theme I use does not support the option of displaying that the website URL is checked for OpenID (a feature of the WordPress OpenID Plugin [1]. Someone who’s […]

Things you can do for your LUG

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 […]

An Update on DKIM Signing and SE Linux Policy

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 […]

Play Machine Update

My Play Machine [1] was offline for most of the past 48 hours (it’s up again now). I have upgraded the hardware for the Dom0 used to run it so that it now has the ability to run more DomU’s. I can now run at least 5 DomUs while previously I could only run 3. […]

Installing DKIM and Postfix in Debian

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 […]

Debugging as a Demonstration Sport

I was watching So You Think You Can Dance [1] and thinking about the benefits that it provides to the dancing industry. The increase in public appreciation for the sport will increase the amount of money that is available to professionals, and getting more people interested in dancing as a profession will increase the level […]
