Dedicated to my late brave, beautiful and silly mummy, Debra Ross. I love you mumster.

Can you categorise too much?

Perhaps the biggest handicap this blog has is the amount of categories I’ve created for it. From sites with a particular focus such as Dave’s Photo Gallery Blog to sites that seem to have everything such as J-Walk’s blog, these guys have figured out how to categorise their information without using thousands of categories to do it.

There are several coping mechanisms that most blogging software come with to deal with this problem: nested categories and tags. With nested categories, you can apply very specific topic pointers to posts which are then contained in more general categories, such as my BSD category within Free and Open Source. This potentially allows you to “collapse” the hundreds of sub-categories you accumulate into just a handful of smaller categories, while still keeping your insane desire for the former satisfied. If you really were obsessed you could have sub-sub-categories within sub-categories, heck even sub-sub-sub-categories within… you get the idea.

Tags are an interesting, if overused and abused, Flickr-inspired development. They let you assign even more specific metadata attributes to your posts which make them not only easier to find on your own site, but in specialised blog searching sites such as Technorati. Not only that but you can be as specific as you like without cluttering up your category lists: for example a post on FreeBSD could be tagged FreeBSD, FreeBSD 7.0 RELEASE, BSD, Kenny Rogers, operating systems, Unix-like and so forth.

ASIDE: For what it’s worth, most of the new unique visitors that make their way to this blog come through via tags. Strange but true!

Then we come to Wikis. I maintain my own locally installed MediaWiki/MySQL system on my laptop (for using as the ultimate note taking application!), as well as my course’s local intranet MediaWiki/PostgreSQL install for collaboration and I’m a proud contributer over on Whole Wheat Radio’s wiki system.

The biggest problem I have with MediaWiki is the ease in which I can assign practically everything to a category, and then categories within categories… within categories within categories! For borderline obsessive compulsive people it’s very tempting to over use them! That said though, MediaWiki generally does a good job with organising them, and allowing you to click through lists of pages within a category you’ve browsed to is very convenient.

I guess my very open ended questions would be (for the sake of my university peers!): is it possible to over categorise a system? Do you have any tips on how you cope with the temptation to start more categories? Is it just a matter of setting limits? Or is Ruben just obsessed and all of you fine people have no trouble with this whatsoever?

Specify image dimensions and save the world!

Jo Anne Hook painting: Australian Wildflowers

One of the more pleasurable things in life is when you can get on your high horse and let the rest of the world know why they’re wrong, and you’re right. Or maybe that only applies to conversations about music. Sorry Elke, comparing Akon to The Rat Pack is like comparing Barry Manilow to Jo Anne Hook. Wait, Jo Anne Hook is a painter. Never mind.

My gripe today is with people who use images in HTML on websites without defining their dimensions! You’ve probably seen pages at one point that seem to rearrange themselves as material moves around to make way for images that are loading. By defining the sizes of images in advance, browsers know how much visual space to allocate them as it draws the page.

Without declared dimensions
<img src="image.jpg" alt="description" />
Using HTML dimensions
<img src="image.jpg" alt="description"
width="320" height="240" />
Using inline CSS
<img src="image.jpg" alt="desccription"
style="width:320px; height:240px;" />
Using an external style sheet
Same as latter, but using an external style sheet linked with an id statement for individual images, or more pratically using class for many images on a page with the same dimensions.

Without this information, the browser is forced to render the page as it would look without the image until it has reached it; this is especially noticeable on slower internet connections and on mobile phones. It also does nothing to help the sanity of people who are halfway through reading a paragraph and suddenly have the text disappear as it’s pushed away by an image that has started loading!

As far as I know from my own experience, Typo, WordPress and MediaWiki conveniently specify image sizes automagically on images you upload and insert, and I assume most other content management systems do too… save for Blosxom of course! Wow Blosxom, the first weblog publishing system I ever used, that brings back memories!

Save the world: specify image dimensions!
