We do this at work - we chain-load gPXE using PXE and then use that to iSCSI boot from a Linux SAN which uses LVM COW snapshots. It's pretty good - the etherboot project rocks! We've been doing it for a while but it always gives me a kick when I type something at the commandline which wakes up a machine using IPMI & then boots it off some SAN volume
There are enough numbers. Each issuer has 1 trillion numbers and there's about a million possible issuer numbers... there's a useful description of the anatomy of credit card numbers at http://www.merriampark.com/anatomycc.htm
Just chiming in with my experiences in VirtualBox... I couldn't get it to do anything - it just sat there at a black screen when I tried to boot a Linux image. No descriptive errors, no apparent activity.
It sounds like you want VMware Player... it's free and I find it a much more reliable virtualisation system than VirtualBox. It's effectively VMware Server without the ability to disconnect from the VM display (since they're trying to push people doing server virtualisation onto ESXi (and then onto their pricey products as a result).
If you want accelerated 3D for free then you want VMware Player 3. The only things it lacks are the advanced snapshots and replay features of Workstation.
LEDs are good if for functional lighting but the light makes everything look very fake (which make them unpleasant to read by, for instance) - they have a very low colour rendering index (there's a more eloquent description of this at http://en.wikipedia.org/wiki/LED_bulb#Remaining_problems).
I work on "cloud computing things" and I can tell you that this is, most certainly, discussed at great length... especially with government-level stuff: these are the sorts of issues that are most important.
Private clouds provide a lot of the benefits of centrally managed infrastructure without the drawbacks of having a single, far-away department managing stuff at the operating system level - it can be a major win for large organisations like governments.
Except operating systems are judged by how many people upgrade (and, obviously the new users you gain), but if 1.0 sells 10M and 2.0 only sells 5M then that's a pretty sizeable failure for 2.0. Obviously in absolute terms it's significantly out-pacing OS X but that's understandable given that almost everyone runs a PC with Windows.
They already do this, as I understand it. The controller on the SSD is responsible for making data stored in various places on flash chips appear like a boring old block device
Oh the dancing will be in another room... (and by myself- this is slashdot after all) the human body spoils the acoustics of my listening environment so I have to leave the system playing, watch it on CCTV and imagine the wonderfully full bass
Still, it's a deal I cannot pass up on! I'll just pop down to your Local Crystal Emporium
Yes, and I'll be happy to sell you one for only $999.99. In addition, if you place this crystal on your speaker system it will smooth the sound, leading to a wetter, more pacifistic listening experience. Supplies are limited, order now!
Hmm, I just bought some new Anjou speaker cables from Pear to make my music more danceable... will your crystal impact the sound? I don't want to spend all that money and find out they cancel each other out!
I should not need to upgrade to a quad-core 8G machine just so I can run email, a browser, AND and office app at the same time, when we USED to be able to do that with a 256M machine just fine.
You ran old applications back then. Your browser probably didn't comply fully with the various specs, support the latest css, the pages didn't have as much heavyweight javascript running in them, it probably wasn't also playing an h.264 video through flash.... new applications do a lot more things and they do them in more depth. You need reasonably modern hardware to take full advantage of them.
That compiling code is the problem - it could potentially be exploited (and the software can't really analyse your binaries to determine if you're being safe and checking everything properly)
Every mainstream programming language has facilities for multithread programming and there's no need to learn a new one just to do it.
Yes, their libraries have the primitives for multithreaded programming but they generally lack the high-level abstractions to simplify concurrent programming - concurrency isn't a core part of the language
Hmm, and it turns out after all these years I've been using blockquote when I should have been using quote:-/ The first line in the parent is the quote & the second the reply
Might I recommend a book? It's a lot cheaper (as long as you aren't a faster reader, anyway). I've also found an iPod to be handy when I want to give my eyes / neck a rest
Ah HA! So that's why you have so many CD Keys. You're from the future, no doubt a history student from the year 3045 coming back to play SC2 beta so you can compare and contrast it with the retail version. But I'm on to you!
and the critical people are being watched too closely to succeed in coordinating a successful subversion attempt.
Sure, you can watch someone's commits. You could examine every single byte of their commits, assuming they were malicious. And you could review the reviewers, assuming THEY were malicious. But you can't stop the spy from doing what they do best: collect information. What if they're finding countless bugs and simply not reporting them? I'd rather have the open source model where there are orders of magnitude more eyes *globally* on the code, able to find those bugs and fix them.
Realistically, though, I don't think any computer system of any great scale is capable of withstanding a long-term concerted effort by an organisation with the vast funding of a global intelligence agency. They have too many attack vectors: modifying the software, collecting information on bugs long-term, modifying the hardware design or firmware or drivers.
Well, research-wise it's not too different - the implementation provides for a longer lifetime but it's not furthering academia much. I see it like all the llvm people who're doing fantastic implementation stuff but largely using ancient well-known compiler research.
uh oh, I fear I'm becoming a computer science snob:-P

I broke my own teeth on this board

And how does one "prove" security again :)?
Oh dear, another person who slept through their formal methods class?
there's no need to break already compiling code

Concurrency is a trivial concept. Coordination is where it gets tricky

I assume the GP is, like me, using Linux at work. I ran into the same thing. Oh well, at least they have a Mac client I can run at home :-)
