Pardon me, do you have the time? Several months ago, we featured a short piece about investigations into clockless computing. Reader xenophrak writes with an update: "Sun Microsystems announces new technology that lets processors run various components of their internals in an asynchronous fashion. The 'FLEETzero' (warning, PDF) chips do not abide by a global clock pulse, and see lower power requirements and heat due to this new feature.
From the web page: 'At the ASYNC 2001 conference, Sun Microsystems Laboratories described FLEETzero, a prototype chip with raw speed roughly twice that of today's chips. Where today's chips use 'synchronous' circuits with a global clock to manage activity, the new, faster FLEETzero chip uses radical new circuits with low-power, asynchronous logic elements that produce timing signals only where and when needed.'
This could have some good impacts on embedded devices, and total processor throughput."
As usual, not so simple. On Saturday you read about Brian K. West, an ISP employee who claimed to be facing unfair threats of prosecution from the FBI for doing nothing more than accidentally discovering a security hole in a local newspaper. A followup posting at Politech indicates that the story isn't quite that simple. Specifically, the FBI's interest in West seems to stem more from alleged attempts at cracking into the violated site than from a simple "found a problem" report. If what the FBI says is true, it changes the story quite a bit.
Time to get a yardstick near the refrigerator ... f97hs writes "Yepps. Delayed almost a week due to regression bugs, the awaited bug-fix release is finally here. Unfortunately, it seems it still can't compile the KDE ARTS-lib (due to, I think, problems with virtual baseclasses). Worth noting is that in order to speed the compiler up, the default to -finline-limit has been lowered. This sometimes leads to considerably slower resulting code, so use -finline-limit=5000 if you compile something you want to be FAST. The mirrors are here and the official release letter from Mark Mitchell might also be worth a read."
