With Vanderpool virtualisation technology, you can run multiple concurrent OSes directly on the hardware.
How is this going to work when both want to talk to the opengl accelerator?
Is this going to require new drivers that are aware of Vanderpool, for each piece of hardware?
The drivers could can check to see if the chip is busy and then handle it as an app in the same operating system had already grabbed the hardware (think what happens when two apps try to play a sound on a single channel sound card).
I thought the idea of this sort of virtualisation stuff was to be transparent?
Incidently, for all the superiority of Open Firmware, most Macs of the past few years can't even boot from USB. While a coworker showed me a 4 year old Compaq D510 desktop with a bog standard BIOS booting and flawlessly running a pirated OS X 10.4.3 from an USB hard disk.
Rewind 4 years and we have USB1.1.
Booting from a 12mbits/s theoretical, 4mbits/s actual interface? No thanks. Macs have booted from 400mbits/s firewire for years.
Back to the present we have USB2, 480mbit/s theoretical. Modern macs boot from that.

I'm not at all excited by the idea of shutting down my computer just to use another operating system.
Anybody who's used a virtualization product like VMWare knows what I'm talking about. That is where it's at.
One word: Games.
Unless things have changed recently, opengl, directx etc don't work.
If a dead process is holding a lock on the database that is blocking other transactions, you just go into the database and you kill the session to the dead process, you don't reboot the server.
I've seen numerous times ghost locks on pages, or even tables by such applications, which only could be released by rebooting the database server and that's pretty bad news in a production environment.
If you can't release client locks on a database without rebooting the server, you've got serious problems with your server there that'd i'd be sorting out before you start worring about the efficiency of client queries.
You got a machine with 200% the amount of ram as your old one. 200% as many processors where both processors run at 200% the speed and with a no doubt vastly faster graphics chip, with more and faster graphics ram ( can't give an exact figure, as a 1Ghz Powerbook could refer to various different models )
Where are these "Christian" extremists exactly, and whose embassies are they burning?
At least 20 people are believed to have died in two days of violence in the southern Nigerian city of Onitsha.
On Wednesday, groups of Christian men wielding clubs and machetes rampaged through Onitsha for a second day attacking any members of the Muslim Hausa community they could find, according to witnesses.
Eyewitnesses told journalists that mosques had been burnt in the city during rioting on Tuesday. "I saw a husband and wife beaten and burnt alive at the River Niger Bridge head," eyewitness Oliver Onah told Reuters news agency, referring to a market area frequented by people who originate from predominantly Muslim northern Nigeria.
You have seen how much money is made by big brother and other lame detached from reality "reality" tv shows haven't you?
I couldn't believe it when i first arrived back in the uk and was flicking through the channels. ITV2 had extended coverage of big brother. I watched it for 5 minutes trying to understand the appeal.
In that five minutes it flicked back and forward between two scenes. In one scene someone was sleeping. In the other scene someone was sleeping. There was a dramatic moment though, one of the people dozing rolled over. Boy i was glad i didn't getup to make a drink and miss that.
It's not like an american painted a picture of the prophet and a bunch of Saudis flipped out and flew a plane into the world trade center.
No, the muslim world has long running disagreements about the USAs support for Isreals historic and continuing annexation of palestinian lands, and for it's placement of military bases on other holy lands.
These cartoons are merely the straw that broke, with the complicit encouragement of the governments in countries such as Syria ( which is a lovely place by the way), the camels back.
That's ok, you just keep your eyes peeled for those Christian suicide bombers boarding your childrens school bus, or detonating that Car Bomb outside your favorite grocery store.
So what was life like in london in the 70s/80s/90s? sounds like you know it well.
If apple or hp etc find that more people are selecting the option to upgrade from 2.0Ghz to 2.116Ghz processor than they anticipated, then they can direct the assembly plant to start putting more 2.116Ghz processors in the motherboards as they assemble a notebook or processor. That is going to result in a greater supply of the faster machines in a day or two.
Such a request to the motherboard manufacturing plant to start making more boards with the 2.116Ghz processor soldiered on is not going to see a greater supply to consumers in a day or two. The assembly line might take longer implement the change, but more importantly you've a couple of steps further down in the supply chain. Once the MBs have been manufactured you've still got to wait for them to be shipped to the assembly plant and then for them to be assembled into complete computers.
They placed a huge hunk of copper with a large noisy fan on that chip. That doesn't make for a Silent PC.
I would have liked to see some testing with a fanless heat sink.
I've got a 800Mhz via mini-itx board that i use for a mythbox. I didn't buy it for low-power, i bought it for silent operation. Nobody wants a noisy PC in their lounge when they're chatting with friends. And your friends certainly dont appreciate the noise the next morning sleeping in the lounge with a hangover.
The C3 chip is pleanty powerful at the moment. With DVD-B in the UK the TV is transmitted as an MPEG2 stream, so there's no encoding required. Playing back divx movies with no hardware acceleartion (unless you count basic video overlay and scaling (XVideo)) leaves the CPU 50% idle. I've yet to try using XvMC to utilise the north bridge/grahpics chips hardware decoding assitance for DVDs etc.
However something more powerfull will be needed one day for h.264 etc, and maybe high-def TV if that ever arrives in the UK or NZ.
A 1Ghz Ultra Low Voltage Pentium-M would be nice for fanless operation, but the CPU alone would cost more than my entire setup (TV included). And is 1Ghz pentiumM going to be enough of an improvement over an 800Mhz C3? Remember the regular pentium-Ms are 2Ghz+ now. An underclocked cheap Turion might be just the ticket if a suitable mini-itx MB exists.
Because he doesn't need any features of a SCM system. He just wants to store some code somewhere so he can access it later. That's what filesystems are for.
As a bonus, turning on one simple option in your editor gives you revision history without having to download install configure and maintain CVS or a similar SCM system.
If the "library" ever gets grander than a few utility classes and multiple people need to work on it, then you can invest the time in setting up a SCM at that point. At that point you will actually be getting a return on the time you invest.
Sounds similar to how they reacted in australia after the nissan team kept winning bathurst and the touring car series. Sure they didn't ban the skyline, they just happened to make rule changes that meant the skyline, and not other cars, had to suddenly start racing with the boot full of lead blocks.
Is there really any point in using CVS or similar when this is a personal collection of code that only one person is accessing?
Why not try using ext3 as your filing system? Set your editor to store past revisions in a backup directory everytime you save. That way you have a history of all the changes you have made.
The C in CVS is for Concurrent. Ain't no concurent when it's only one person. CVS is overkill.
Also, have you considered using a language like Java where you'll find such 'oft-used code' is part of the standard library set and you dont have to write it yourself, leaving you to concentrate on writing the code that is unique to the problem you are solving?
From TFA: "According to the initial investigation, the application uses Spotlight to find the other applications on the infected machine and subsequently inserts a stub of code into each application executable."
So it infects other applications without user intervention.
Remember, the term virus was in use long before networked machines were common. Self propogation doesn't have to mean infecting applications on a different machine.
Good thing they banned Rotaries from Le-Mans to prevent a repeat of that outrageous result; some young upstart japanese company beating 100s of years of european automotive development, can you believe it, Mazda cheating like that and they got away with it.
What a great move by the Le-Mans organisers, such foresight, and it's really helped push the automotive industry forward.

The openchrome drivers support XvMC for hardware MPEG decoding.
It's the MPEG4 part that doesn't have opensource drivers, but my SP8000E plays divx on the plain old CPU with 60-70% idle. (mplayer and Xv output)

alright, so it was based on DOS
It wasn't based on DOS! It used DOS as a bootloader. There was a security option to unload DOS when you started netware.
