Ubuntu has build in support for Compiz fusion now called just compiz since version 8.04 I believe. But the plugins included haven't really been increased in a while. So most of us are missing out on some of the creativity and downright oddness coming out of experiemental corners of the internet. Theres a whole page of how to get the plugins from GIT if you want to take a walk on the wild side.

Amusing little video about the new HP webcams which don't track black faces, but will happily follow a white face. Racist no but Black Dezy did have me chuckling, specially since he bought one. Recognition software isn't always what it should be, for example some of those voice recongnition systems can't deal with the deepness in my voice and never catch any of the numbers or words I use. Very frustrating when you know your not the problem in the chain. I expect the camera just can't cope wit the lighting of the store/office and if you shine a light from the front it will work.

I'm convinced that Xquery is somewhat the non-elegent child of the xml family of technologies. Every single technology from XSL to Xpointer, Schema to XMLencryption seem to pick part of the puzzle and do that bit very well. So you can forgive me for thinking Xquery would only be useful for querying data from a xml database, somewhat the SQL of the XML world right? Nope, in actual fact its not only SQL but also PHP and the XML doesn't even have to be in a database at all. The crossovers with XSL is quite shocking for such a elegent family. Fear not, Xpath forms a large part of Xquery meaning us XSL lovers can jump straight in and feel a little at home with its strangely non-xml syntax, I actually quite like writing xml to create/transform xml. And if things get a little too weird in Xquery land, you can run for the beach by telling Xquery to do a XSL transformation on a tree of data instead.

Although it doesn't quite fit, its actually darn powerful and beats messing with XSP or other templating languages. For example, in about 6 easy to understand lines of Xquery, I was able to pull down a XHTML document, rip off its head element and append the body inside a ATOM feed. I could do the same with XSL but it would be much more lines and the way Xquery is setup, it seems to make more sense. One of the big issues people have with XSL is that it doesn't know anything about its environment. So for example calling the present time would require looking up a webservice or some other external logic like PHP, XSP, JSP, etc. Well with Xquery, you get all that type of logic which you could even pump into a XSL transform.

I'm learning Xquery right now mainly through Exist DB and this nice wikibook, which I converted to PDF using the wikibook system for offline reading and reference on my Ebook reader.

I saw this on Ben Metcalfe's blog recently…

It’s my first time working with RoR and I’m really enjoying the experience. Pivotal Tracker continues to be an amazing productivity tool for development, and I’m beginning to wonder how I ever worked before DropBox, EtherPad and BaseCamp.

Got me thinking what tools do I use which I just can't work without.

Dropbox is high on my list. First thing I do when installing a new machine is install dropbox, because has my desktop backgrounds, application settings and all types of good personal stuff which I use day in day out. I've also considered there pro upgrade for the purposes of work. Its like the promise of Webdav without the stress. I like the way I can work on a file on any of my ubuntu machines and then flip to my work windows machine and carry on where I'd left off. Save and Sync, then i'm back to my laptop. I use symbolic links to do drop torrents from anywhere, sync bookmarks and exchange configs. I want dropbox on my Sony Ereader and on my phone (Windows Mobile 6).

Basecamp I do use at work a lot. But to be honest in recent times its starting to look and feel the poor cousin of Googlewave, Etherpad, etc. Basecamp is great because its project management done to the level which I'm confidential I'm not spending time filling in crap like project but acting too loose like on a wiki. The problem is basecamp is a web only system and not only does that restrict what kind of projects I put on it but also makes it a pain to pay for it out of my own budget. What I really want is Basecamp inside of Wave as a robot and series of widgets or Basecamp with the ability to install on your own domain/server and federation support.

TomboyNotes is where I store all my notes which I can't remember. Its great and simple but I do wish it would work on my phone or at least as a webservice (Snowy will solve this problem). On the gnome desktop tomboynotes is quite well supported (plus it runs on all 3 main platforms), so theres plugins for a lot of things you may want but its not really as smart as Evernote which I started using but got fed up of due to their attitude to gnu/Linux users. Using, I'm also meant to be able to turn Tomboynotes into a lot of other things like a basecamp backpack (although this doesn't work for me anymore). I do use dropbox with tomboynotes, so I can sync notes between machines without a problem.

Hamachi is my personal VPN network I have on most of my own machines. It runs pretty smoothly on most of machines even old Pentium 3's. I keep wanting to go the either the OpenVPN (which I just don't get), Ntop N2N which I struggled to get going too) Wippien which has recently come to my attention as a Hamachi but with open decentralised lookup server. But I find myself using Hamachi for its pure ease and clever things it can do. For example because every node on the VPN act like local ethernet, you can use mnds/zeroconf, run pulseaudio from any home machine or use ssh/samba/webmin/vnc over VPN into any machine attached to the vpn.
