Scons keeps track of dependencies using MD5sums on the tail nodes.
I'm not familiar with SCons, but this doesn't compute. The problem with make isn't with recognising changed files, it's identifying dependencies in source files (hence 'make depend').
'make clean' is an artifact of changes to the build environment that are not properly represented in the dependency graph. Looking at SCons, it appears the authors have a few neat ideas, but I fail to see how a different management tool will help in working out the dependencies.
ant is nice if you want to work around the inefficencies of starting up multiple VMs from the command line (the inefficencies should be addressed on the OS/VM level), and if you want a cross-platform build environment if you can't establish a POSIX shell environment. Not particularly bad, but to really brilliant either...
Intel outperforming PowerPC was kind of expected. However I am impressed with a technology behind Rosetta. Are ther any open source projects like that?
EMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation.
It can run (to some degree; it's still in development) on x86, amd64, PowerPC and a host of other CPUs, and it can run binary code for x86, amd64, PowerPC, SPARC, ARM, and MIPS.
For your convenience: 'Heard on a Virgin flight from Brisbane to Sydney: "for your convenience, the cabin will be pressurised". How about, "so you don't die, the cabin will be pressurised" or just, "the cabin will be pressurised"?
I can see where they're coming from: very few people realize that at normal crusing altitude (average 33,000 feet), when the cabin depressurises, you have about 20 seconds to get that oxigen mask set up for you to breathe through.
Ever wondered why you should help yourself first, and then any "children accompanying you"? Because if you help them first, you'll be unconscious before you can effectivly help them.
I don't agree hiding these facts from the passagengers is a good idea, but corporate communications is rather concerned with "making people feel good"...
Its too bad that HP couldn't throw some money into the kitty. Then again, they have a history of abandoning chip technology in favor of deals with Intel that sometimes are disasterous.
Maybe DARPA could do something with PowerPC that would be worthy of a defense contract to keep the R&D up.
Too little too late. Sun/FujitsuSiemens are the only contenders left, and I highly doubt they have the muscle or intention to go with Intel/AMD head-on. SPARC is a direct competitor to the high-end IBM Power 5 and Power 6 offerings, and I'm not sure either Fujitsu or Sun have the volume to make it work. Sun apparently even has trouble fabbing at 90nm, let alone 65nm, so they're lagging behind IBM, and I don't see that changing any time soon.
[IBM and Freescale] both keep their PowerPC lines, and the desktop sales were never particularly important to them.
But that's the point: Apple was the only customer left for high-performance desktop CPUs. IBM has a foothold in the high-end (Power 5 and Power 6) and embedded arena; Freescale pretty much focuses on embedded. Both have done so the past eight years. Neither was willing to foot the bill to develop processors for Apple and be unit-price competitive with Intel or AMD offerings.
Irrespective of whether The Steve dealt properly with IBM, the reality is and has been for many years that developing their own CPU (or having it developed for them) was just too expensive for Apple.
The original idea of the Apple-IBM-Motorola coalition was that they would be able to compete with Intel by combining forces: CPUs for servers, workstations, and embedded systems; and by creating a third-party systems market to drive demand for these CPUs (PReP). This never really took off, so IBM and Motorola were stuck with having to compete with Intel for price/performance for a single customer that would only buy a fraction of what Intel and AMD would churn out. I have no idea how much it costs to keep up a competitive CPU architecture, but it must be in the hundreds of millions, if not billions per year.
Cell might be cheap, but it doesn't allow Apple to compete with PCs on a price/performance or performance/watt level. And paying IBM to continue to develop the 970 architecture was just too expensive: people might be willing to pay a bit more for Apple systems, but only so much.
Just look at all other contenders in the high performance CPU market: there's nobody left except for Sun and Fujitsu/Siemens, and they announced last year that they will cooperate on SPARC. From a pure market standpoint, Apple had little choice.
Also, Apple has to pay import tariffs, and I wouldn't be surprised if they were higher in the EU than in the States. Additionally, Apple has to grant a 2 year guarantee.

He might lack the practial experience on how to best configure color-ls, but he's designing and implementing an operating system, for example? To read the code, you don't need to run Linux...
It's really interesting to see that all the entries modded high advocate force. Forcing people to comply to policies that are incomprehensible to them. Policies that shut out non-Windows users because there are no "application-level firewalls" and "comprehensive anti-virus" packages, nor "malware detectors". Any other time, the loudest/. posts want the vendors to take responsibility, to educate people, to make them switch to platforms that are inherently or at least accidentially less likely to fuck everybody up.
This time, it's retaliation for being treated poorly as geeks? Or what?
OK... they lit up the equivalent of two OC48's worth of bandwidth. That's half of an OC192 or a 10G Ethernet. There have been long haul OC192's for a number of years now. If I hook up a hardware-based traffic generator and run at 100% over an OC192 for a few weeks will I get a slashdot article, too?
The accomplishment is not in the data rate, it's in the ability of the participating organisation's to get a stable network going. One that is close enough to the one that the real scientists will be using in a couple of years.
Consider that there's a large number of institutes, universities, etc. that all have their own IT departments, plus all the physicists that have to be involved because it's their grant money funding all this. It's thousands of people coordinating. And I would be surprised if they hadn't set up different service classes, priorisation schemes and what not.
Setting up a trivial network between a couple of sites that are all under your control is close to trivial: you just need to talk to you telco and buy the lines, and hook up the routers. But establishing a working network between these many institutions takes a lot more.
Time how long it takes from pressing <enter> [to] when you can see the main Google page. Try this with both Linux and Windows XP using Firefox as the browser.
The real difference is, with Windows you have to reboot so often that boot times really matter.
Honestly, how may times a day do you reboot or power cycle your machine?
Willful copyright infringement is a crime, under certain circumstances. I'm sure the FBI and/or AG would have been willing to listen to Apple's lawyers' arguments...
Most systems I set up these days have so much RAM I just skip swap entirely, unless it's a production server: if you do want crash dumps, your swap space needs to be big enough to hold the dump.
Saved my ass once on a big database server where Oracle was triggering an obscure kernel bug; the customer I set the machine up for didn't want to "waste" so much disk space, but I insisted. Since the problem only occurred after several weeks of uptime, he was really glad we were able to identify and resolve it the first time it happened...
Don't have any links handy, but equipment like this is illegal to import into the EU, or buy or sell here, let alone operate. (IANAH, but I've play with comms electronics enough to know...)

QEMU aims to do the same:
It can run (to some degree; it's still in development) on x86, amd64, PowerPC and a host of other CPUs, and it can run binary code for x86, amd64, PowerPC, SPARC, ARM, and MIPS.
What is this, lame projects day? First an ugly, loud, useless "rack", then a crappy, ugly shelf, now this?
