Anyway, Drip is a memory leak detector application for Internet Explorer. It basically runs IE within the application itself, and analyzes the memory usage for any leaks. Seems really really useful, and just by playing with it for a few minutes I already found a couple of pieces of code to fix.

Steve Souders wrote some thoughts on performance improvements happening in IE8, with their change to support 6 parallel downloads from the same hostname at the same time.
According to Steve, there’s a big difference for some sites. Facebook for instance takes a 80% performance gain while using IE8 and having an empty cache.
By the way, I didn’t know Steve had a blog — Subscribed.
I just spent quite a bit of time debugging this silly problem on Insightory.com, where the document control buttons were not working under Internet Explorer. Since it might be useful to somebody else, I’m going to document the solution here.
The problem was that the document browsing control buttons, which look like the following:
<img src="/blog/browse_controls.png" />
They were implemented by doing something similar to this:
And then inside the openNextPage function, I swap the image by changing the src attribute of the image tag. Pretty standard, and works perfectly under Firefox.
I found out the culprit by (obviously) searching Google for a long time, and then finding this thread on WebDeveloper.com.
