In the past couple of months I thought about spending some money on either a Nintendo Wii or a multi-purpose media box (not to mention my anxiety over buying an unmodifiable blackbook). Over the past 3 years I’ve looked at smaller cases as “better”. Before that it was always the full tower case that provided more room and ease-of-use. In this vein I’ve been looking at the world of mini-itx for the past several months.

VIA created the mini-itx specification for itself, but since its creation other companies started creating motherboards with this spec and recently so has Intel. The spec allows for a low-power consumption CPU, which is great for point-of-sales machines, thin clients, and more. The other use of mini-itx, popular amongst personal users, is as a Home Theater PC (HTPC) or media center.

(First, yes I do realize the ‘X’ in ‘OS X’ is pronounced “ten” not “ecks.” I simply like the portmanteau.)

With the release of Leopard, I discovered the need to migrate my existing Tiger system onto an external drive. I needed it to be bootable, and I wanted to have a little discontinuity as possible. Apple generally makes this pretty easy, but it’s still a bit involved. I write this article from my migrated system, currently booting Tiger off of a USB drive.

People like their applications to work. Even better, they like them to work, even when things change. For the WinTel world, this isn’t a big deal (Vista aside ;), because the underlying CPU architecture hasn’t really changed, from a program’s point of view, in the past two decades. Unless you have a weird program that’s designed for AMD’s 3DNow! instruction set and you switch to an Intel CPU, or perhaps an application designed for a more esoteric old SIMD architecture, your application should run just fine (as long as your Operating System is ok with it).

Mac OS X doesn’t have the luxury of working on the same underlying CPU though, so things need to be handled a little bit differently. The solution Apple came up with was

The Kineme Quartz Composer patches now have a proper home at http://kineme.net/, including forums, bug reports, comments, and feature requests – complete with voting!

Along with the new site, a few new patches are available as well based on requests from users.

While writing the new Image Downloader (Blocking) QC patch for CoreMelt, I ran into what appears to be a bug in Mac OS X’s NSURLConnection framework – if you construct an NSURLRequest and specify a timeout of less than 30 seconds, it’s ignored when you perform a [NSURLConnection sendSynchronousRequest:returningResponse:error:]. The request takes at least 30 seconds to time out, contrary to what the documentation suggests..
