I assume they mean Qt application, not QuickTime, or whatever.

If the first thing that enters your mind when reading "QT" is QuickTime, you're on the wrong website I'm afraid.

It's usually rendered as Q t not Q T .

The fact is that a full BIOS + Linux / Windows system is a horrible fucking mess of bloat
It's also a huge pile of capability that wasn't around 20 years ago. I find it hard to believe that, capability-wise, your Acorn A3000 was on par with a modern PC. I don't see it as bloat, but as the necessary result of supporting a wide array of capabilities (not necessarily hardware) and an extremely capable and platform-independent environment.
BIOSes (especially RAID) are the slowest part these days, and UEFI is hopefully going to combat that.
Function re-ordering inside the image? wow (Score:5, Insightful)
I have to say, the most impressive/innovative tweak, to me, was the re-ordering of required functions in the compiled binary. Doing so allowed them to reduce load time, by making it that only two blocks had to be demand-read off the flash filesystem, instead of four.
That's some crazy, use-the-drum-spin-as-timing, innovative thinking right there. Serious kudos.

Your Acorn A3000 held and executed most of the OS from ROM. When you don't have to copy from disk times are much faster.

can we please get back to arguing now?
Yeah, right after I finish beating Doom III by "I.D." software running on my "MAC".
I wouldn't be surprised if the poster pronounces daemon as "daymon" either. The geek ego sure seems to get in the way of learning how to pronounce things. It looks like devs these days will have to provide audio files [kernel.org] to show how to pronounce their work [irssi.org].
*shakes his head at correct pronunciation deniers*

CarPC? HTPC? Just being able to turn the computer entirely off when it's not in use rather than suspend?
This particular example was focused on embedded applications, but the general idea of being able to boot a computer reasonably close to instantly is advantageous pretty much anywhere.
