one application for cloud-based supercomputing is things like FEA and CFD, and for those the inputs and outputs are relatively small (compared to the numbercrunching inbetween). Autodesk has an online FEA service as part of their Inventor Pro package that seems like it will bring them business for large models/meshes. sometimes the hardware cost isn't as much as the software cost. the op mentioned linux, which is free, but what good will that do on its own. big numbercrunching analysis packages like FEA usually aren't cheap, and the cost to develop your own software is always high.
I find that the better the amplifier hardware the bigger range of music becomes tolerable. Britney on a cheap boombox sounds like crap (duh). Play the same thing on something half decent and there will be more music, less Britney so of course it will sound better:)
I'm not a fan of midrange in general (nor hissing or thud). I don't think that makes me in the same league as some audiophiles but I'm a little pickier than your avergae Britney fan. I like to be able to feel bass (particularly in movies) and be able to turn the music right up without my ears being blown out by midrange and higher frequency distortion. Anyone who cranks up their sound system enough to get bass distortion is obviously a dickhead but even cinemas and nightclubs have given me headaches with "noise".
btw, how did we get from supercomputing to Britney again?
if the kernel source code has been compromised, then every linux computer updated since the attack could be infected (maybe even set top boxes, corporate database servers, etc).
BUT...
because linux is open source, the kernel developers should be able to just compare the suspected compromised source code with a backup from before the attack (or just go back a year and copy in known fixes) and then every computer with a compromised kernel could just run their update program (which is probably how the infected kernel was installed in the first place) and update the kernel with a fresh clean copy. many computers (especially headless web servers) probably autoupdate critical security updates from their distro repos anyway (mine does).
i've had a squiz at the kernel source code in the past and i would think that something injected to prevent the update programs of every major distro from replacing the infected kernel with a clean one wouldn't be very easy to hide. if it simply puts an extra line of text in the bootup sequence that says "linux now has super cow powers" then that will merely make for more interesting slashdot news.
As a user of linux I'm not worried. I have more faith in the linux kernel developers in getting to the bottom of malware issues than any proprietary software development company (you know who i mean).
i'm not familiar with it, but i'm sure git is a good system that gives linus and his minions the ability to efficiently and effectively track down whatever changes may have slipped into the kernel.org versions.
and since the world relies on linux for more than just surfing the net and playing freecell, if serious damage results then it might give governments/corporations some incentive to give a little more support to keeping linux secure in the future.
after all, what other operating system could act as a drop-in replacement for the linux kernel for what it does? really?
Yeah I could see how that would be a problem - "Captain's Log, Wednesday, 12:32 pm Jupiter time. We have entered... um. i mean... oh shit what day is it again? Spock!, are we in the Jupiter time sector still?"
This: "I'm your worst fucking nightmare...a retailer that still believes." sums up all your rage against Linux... its a totally awesome operating system... THAT YOU CAN'T SELL FOR A PROFIT!!! hahaha. poor thing. Re: "WTF does what he did in the past matter now"... i guess the people who invented the transistor don't matter to you either. maybe you should join the hippies and abondon technology altogether you ungrateful worm. Re: "What corp in their right mind would be running 16 bit apps nearly 15 YEARS after support ended? Security hole much?" whoever relies on applications (or the thunking to run them) for security is a moron, and its not a case of corps being in their right mind; they may have no choice if there's no alternative. not every company uses photoshop or autocad that keep forcing you to upgrade; i'm talking about CAM, datalogging, POS, etc. some programs are also good as they are. just because operating systems don't want to support them anymore doesn't mean there is fault with the 16 bit app. if it aint broke don't fix it, and some 16 bit apps work very well for what they do. i'm not a linus kiss arse as much as you clearly despise him. i merely appreciate that he paved the way for the OS that i now freely use. why do you insist that linux must compete with windows? linux isn't about profit or market share or usage. are you too thick to realise. nobody except microsoft shills really give a shit, but its still fun to get you all wound up:) the rest of your post was pretty funny stuff... "cower at the truth". you're a nutcase dude. insults won't make me cower, and i'm not going to treat anything you say as truth because you're a known bullshit artist. not that i mind; keep going because its quite entertaining.
its funny that tcp didn't feature anywhere in your how it works summary, and it took all of what you said to basically repeat what i had already said in one sentence "everything to do with maintaining the instance of the program doing the copying". thanks for the info though.
re: "first link..." - why would i search when your content to do it for me. so predictable:) tahnkyou for the info and this discussion as a whole has been enlightening. i didn't know about live migration before (i think the latest i heard of is now called "quick migration"). its been fun teasing out the info.
haha i call shill (actually your already a known shill). linux was never designed for "the desktop" or for making money. that it has made any headway at all is merely a side effect. you go have your wingasm but i won't be joining you because your jealousy of linus really stinks.
Re: "I think you should take a bit more time understanding how a network connection really works. I.e.: learn that from its very begining TCP/IP was conceived to work through unreliable lines so surviving a dropped packet here and there is already taken into account in the very protocol."... what does this have to do with live migration again? "copying a file has as much to do with tcp as saving a document has to do with FAT32" was merely to highlight that while tcp is in there, live migration requires maintaining the copying process (higher level). i don't know where you were going with the networking thing or why you thought i needed to brush up on it. also, would it comfort you if i said i was insane? i like to think a bit more critically rather than blindly accepting whatever someone tells me (including google/wikipedia/microsoft/slashdot) so challenging common knowledge isn't beyond me. i would be happy to be lumped into the same class as copernicus, but of course the sun revolves around the earth!
this would of course only be a problem if you *wanted* different guest hardware. one advantage of a virtual machine is that you can have all the same virtual hardware on different physical hardware. i found out a little about live migration (did i hear you say "omg!") and it does seem impressive - failover with incremental memory copying. definitely datacenter stuff. if you design your network right a regular failover cluster can be just about as good though.
wow! you think i'm authoritative? lol you poor thing. perhaps you should get out of your datacenters a bit more often (joke). i'm simply having an online discussion, and so far its been quite entertaining (as always on slashdot). apologies if my assumption was off... there are a lot of shills promoting all sorts here (as you're no doubt aware); i figured i probably had at least a 20% chance of getting a bite:) you're right about me not having experience with virtualisation, but it doesn't mean i'm totally ignorant... and if i don't know i can always just wing it. i find its a good way to learn because there's always people here that will jump at a chance to prove me wrong and demonstrate their superior knowledge. google is good, but it doesn't know everything and i still have to wade through commercial shit (even wikipedia's page on live migration is pretty disappointing).
i didn't say it was impossible. i even said "i would be quite happy to be proven wrong". the problem with your latest attempt at bewildering me with bullshit is that it would seem possible to migrate a suspended guest os to identical/similar hardware. you would be taking a pretty big risk trying to resume a host on a different machine without any problems, and i'm guessing you would need a volume license for a windows guest for activation. no i haven't googled; its more fun winding you up:)
being able to migrate a guest os to different hardware without interrupting a file copy has nothing to do with tcp and everything to do with maintaining the instance of the program doing the copying. perhaps you are more ignorant than i gave you credit for.
you're most convincing statement in your reply was "Take my word for it: it is not aborted.", and only because it would seem from it that you have tried it yourself. now take my word for it: all the rest was bullshit. copying a file has as much to do with tcp as saving a document has to do with FAT32.
what i find amazing is that you can be so offended why what he says. what did he personally do wrong to you that he didn't have every right to do? what way did he mistreat you that was different to anyone else? what do you think he owes you? just because people listen to him doesn't mean he has no right to voice an opinion. i don't think anyone could doubt that he's done a lot for linux, FOSS and the IT industry in genral, and because of that people listen to him, whether you like it or not... also, a lot of software used by companies is still 16 bit. just because microsoft (or you) say its old doesn't mean it should be forgotten. re: "you have ANY leg to stand on when it comes to BC" and the rest - i don't really give a crap. if you hate linux and love windows then good for you. i don't use linux because i hate windows; i use it because its useful for me and because its free. i reckon linus seems like a decent enough bloke who is pretty smart and a lot of people are jealous because you can't buy his credibility.
... an who would do this other than a datacenter? your example (amazon) wasn't really a good one for proving whatever point you were trying to make, because amazon has huge datacenters.
lol i didn't actually say that. i said "datacentres use virtualization merely to squeeze more servers out of their existing hardware (equals more paying customers)", which doesn't imply any more money out of each customer.
you didn't happen to mention any other uses (not very convincing), bashing windows will always be funny (duh!), you not heard of mysql cluster or shared storage, i would be interested to know which virtualisation solution allows migration to different physical hardware without terminating file copies, and all this stuff seems awfully datacenter related... funny that. i'm not an expert on the mechanics of every virtualisation solution out there (my op was an opinion - obviously, but i do use virtualbox), but virtualisation is clearly your only area of expertise.

you're apparently not familiar with the US legal system... in which there is much to be paranoid about (whether you're a lawyer or not)
who is fred phelps?
- my google button is broken and my computer is infected with the "w32.microsoft.windows" virus, and the drug store says there's no cure for it!
xxx domains will be charged an "adult industry communication tax"
reeks of revenue-raising to me. why xxx over the myriad of other possibilities? of course its because sex sells.
