Browsing Java documentation on Sun's Java site is incredibly frustrating because the site doesn't seem to support a basic operation I want: search.
Consider this example. I performed a Google search for java.util.Map.Entry and eneded up on this page. It has a lot of useful information on it. But now that I'm there, I was to search for something. I guess I have to go back to Google and start over. There's no search box on the page. WTF?!
Contrast this with any reference page on php.net, like this one (chosen at random). It's far more search friendly. There's a box right at the top of the page and a drop down box that helps me crontrol what I'm searching.
php.net docs: good.
Sun Java Docs: less good.
Oh, it's not just PHP. The MySQL folks get it too. Here's a randomly selected example from their docs. Notice the search box.
There's an excellent article on IBM DeveloperWorks that presents a performance analysis of the 2.4 and 2.5 kernel's hyperthreading support.
Good stuff. I look forward to the enhanced scheduler in 2.5. Perhaps it's one of the few reasons we need to consider using Linux rather than FreeBSD for MySQL at work. MySQL, of course, is heavily multi-threaded.
