Ajax and the common man

One of the hot new(ish) things in web design is Ajax – standing for Asynchronous Javascript And Xml. To quote Wikipedia, “The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire Web page does not have to be reloaded each time the user makes a change.” You’ll have seen the results on websites like Flickr, where you can edit the descriptions on your photos without having to load a new page. An impressive example of an Ajax-rich WordPress theme can be seen here; click on the buttons at the top to get the full effect.

Which is great, of course. Except that one of the joys of the internet is its accessibility for the casual user who wants to make a webpage. HTML is, really, an extremely simple system to use. CSS means a bit more to learn, but once you get the hang of it, it actually makes your life easier. And that’s all you need to arrange content on a page. If you just want to create a static webpage, you can do it entirely from scratch just with HTML and CSS, and how good the content is and how good it looks are entirely up to you.

Even using software like WordPress, it’s easy enough to just use some knowledge of HTML and CSS to restyle the output. The software is built in PHP, and you just have to work around the PHP tags, moving them around as necessary; it’s usually obvious from context what they do. So you can completely change the look of a site without doing any of what I’d call real coding. The various changes to the appearance of this site and its predecessors have all been done without me knowing any PHP. Ajax kills that, as far as I can tell; hacking around a theme to change the styling becomes a suddenly much more technical exercise.

I completely see the point of Ajax – when it’s used well, it transforms the user experience. And I’m not suggesting that anyone stop using it just for my sake. New software makes it easier and easier for people who know little about computers to share their thoughts and pictures on net; it’s just an unfortunate side-effect that as the software gets more sophisticated, it gets harder for a dabbler like me to get my hands dirty and tinker with the machinery.

I guess it’s a natural progression with all technologies. In the early days of motoring, you *had* to know how to do basic repairs to your car by the side of the road, and the engine was simple enough that you could probably do it with a couple of spanners and a can of oil. The fact that cars are now so reliable that you barely need to know how to check your oil and tyre pressure is a Good Thing, of course. But it still seems a pity when things get professionalised out of people’s hands to the point where they never get to do things themselves from scratch, whether it’s baking bread or creating a webpage.

And it took a while, but the future may finally be here.

Galileo satnav

The first satellite of Galileo, the EU’s competitor to GPS, was launched yesterday – initially to test out the kit, with the service planned to go online in 2010. One of the explicitly stated aims is provide independence from reliance on the US government, since GPS is a military system that is made available for civil users at the discretion of the government and, presumably, the Pentagon. I’m always intrigued when interaction between Europe and America slips into rival-Great-Powers mode, rather than the usual closest-allies shtick.

In practical terms the project sounds pretty sane to me anyway (not that that I know much about these things). In future, I’m sure all the devices that currently use GPS will be designed to use both – Galileo is designed for compatibility with GPS anyway – and the number of GPS-equipped things will increase for some time yet. The combination of GPS and Galileo will provide better accuracy than either of them alone and will provide backup if either goes offline for whatever reason. So it’s not a redundant system just reproducing the functionality of GPS.

Whether all that justifies the cost is another question. €3.4bn sounds a lot, but it pales in comparison to the €50bn for the Common Agricultural Policy this year. I think it’s probably a good idea, but then I am a bit of a geek.
