I’ve been very slack in mentioning that the 2006 London Perl Workshop is go! It’s being held at Westminster (because they pretty much rock) and we’re looking for potential speakers. If you’ve got something interesting to say about perl please have a look at the Call for papers and seriously consider submitting a talk.

I’ve re-written bits of the category and archive Blosxom plugins to output CSS friendly markup. Which I’ve added some CSS to. The changes are mostly non-intrusive (and most of my traffic comes through RSS readers anyway) but if I’ve painfully broken anything for your browser of choice drop me a note.

Authors: Dan Farmer, Wietse Venema ISBN: 020163497X Publisher: Addison Wesley Forensic Discovery is a small book that packs a big punch. In just over 200 pages it presents more information than books three times its size (and weight). The book is divided in to three main sections. The first, “Basic Concepts”, explains two of the books core ideas, the order of volatility, how it influences the gathering of evidence, and the importance of time based information. Read on →

The Nagios monitoring system is a great example of Free Software, powerful, flexible and easy to extend. While it comes with a lot of functionality out of the box you’ll occasionally want to write you own Nagios plugin; which isn’t too hard to do. The plugins below have all been written by me to help keep my systems under control. They’re functional, released under the GPL and hopefully useful to someone other than me. Read on →

You start off with a couple of partitions. You add a MySQL instance and put it on a new logical volume. You break its logging out to a different volume group for performance reasons. You take a snapshot for query tuning and mount that. You add a chunk of disk for a short experiment you were going to try… thanks to legacy, laziness and easy to use LUNs you eventually end up with more mount points than you know what to do with.

…I just look like it. I’ve spent the last week and a bit wrapped up in bed fighting the flu (and it won). I’ve been a good boy and stayed off-line in an attempt to keep the headaches tolerable so now I have the joy of nearly a fortnights backed up emails; and the same again in my work accounts. I’ll be (slowly) working my way through the pile from tomorrow. Read on →

I’m subscribed to a lot of RSS and Atom feeds. I’ve tried online readers but I never found any that could match the user experience of SharpReader so I stuck with it on the desktop. But now I’m starting to want some functionality that none of the readers I’ve looked at seem to include. Firstly the easy stuff, when was the last article posted on a blog? When was the last time I clicked through it? Read on →

There are a couple of webcomics I read on a daily basis (a couple a week in the case of MegaTokyo) and recently I’ve found myself wanting to link to a couple of different strips in blog postings; and then discovered that they’re almost impossible to search through. None of the webcomics I read regularly have any kind of strip content search. You can’t see who was in which strip, you can’t search on the punchlines - which is what I want - and, apart from a couple of sites which have a one sentence summary, you can’t get any more context about any days issue than the time it was uploaded.

Each year I put a small todo list up on Unixdaemon and see how many of the goals I can meet. The 2005⁄2006 Pragmatic Investment Plan is now closed so it’s time for a quick look back. First up we have the writing of articles. I’ll come to this in a separate post as I’m still not happy with what I want to say. Training courses are an easy one. I did two main courses and I can’t remember much from either of them. Read on →

For my own use as much as anyone elses… One of the problems that’s haunted me at least once per company I’ve worked at as a tech is “the disappearing partition”. It’s there, it’s accessible, and it should be persistent across boots. But it isn’t! The machine reboots and then you discover that the database partition is no longer visible. The check mounted disks Nagios plugin looks at the mounted partitions and compares them to what’s in /etc/fstab (minus a couple of things like cd drives, floppy disks, swap partitions etc). Read on →
