More useful WordPress plug-ins

June 22, 2007 No comments

Apart from a widget that puts a login form onto a blog sidebar, I am not really on the lookout for WordPress plug-ins but here are two that came to my attention recently. I have found them to be useful; maybe you will too.

The first is WordPress Admin Themer. This allows you to store wp-admin.css in your blog’s theme folder, out of harm’s way from future upgrade cycles. A neater way of otherwise storing your customisations of admin pages – I keep changing the logout destination to the front page of my blogs – would be a bonus but the style plug-in is a good step forward.

One use to which I was going to put WordPress Admin Themer was to hide some elements of the WordPress dashboard page but I happened accross another plug-in that does just this kind of thing: Dashboard Editor. Activating this gets you an extra admin page where you can select the components that you want to see using the tick (check) boxes. You can even take things further by having your very own dashboard instead of what WordPress offers or by activating widgets for using with your dashboard. It’s all good stuff and I have got rid of extraneous pieces such as Planet News and the getting started section (I have using WordPress long enough that I should know my way around by now…).

IE6 and JavaScript performance

June 22, 2007 No comments

Having been exposed to an application at work that uses a lot of JavaScript, I fully appreciate what some mean when they talk about IE6′s inefficient handling of JavaScript. After seeing a web page taking an age to reload and your CPU taking a hammering because of JavaScript processing, the penny does tend to drop… Needless to say, this very much impacts the world of AJAX-driven web applications with their heavy dependence of client-side JavaScript. While IE7 does come to the rescue, there remain plenty of IE6 users still out there and this is reflect in website statistics. This reflects a certain level of inertia in the browser market that not only afflicts the uptake of IE7 but also the likes of Mozilla, Opera and Safari. It also means that anyone developing AJAX applications very much needs to continue testing in IE6, especially if the product of their labours is for wider public use. An example of such an application is Zimbra, an open source web application for messaging and collaboration, and the people behind it have generously share the results of their browser performance benchmarking. They did comparisons of IE6 vs. IE7 and Firefox 2 vs. IE7. IE6 easily came out as the worst in these while Firefox 2 was the best. I suppose that the next question to be asked centres around the type of code that is processed inefficiently by IE6. I wouldn’t be at all surprised if a list emerged but here’s one: using Microsoft’s proprietary innerHTML object to update the DOM for a web page format. Having a quick trawl on Google, this came up for mention as a cause of memory leaks. It is also a Microsoft innovation that never got taken up by those overseeing web standards, hardly a surprise since a spot of DOM scripting achieves the same end. It may be faster to code than any alternatives, and it does have some support from other browsers, but it does seem to have got a bad name and so should be avoided if possible. That said, it would be interesting to see a performance comparsion between innerHTML and DOM methods in IE6.
