iirc education licenses are upgrade/downgrade only at least thats what the IT pages for the university of manchester say. So the OEM license is needed (some people break this rule for individual machines but i doubt anyone would dare to buy a labfull without OEM windows).
Its not quite as bad as paying double though. The OEM licnse can be a home version which claws back a fair bit over just buying the boxes with pro and i stronly suspect that to tempt the university into a subscription based site license required a pretty extreme discount.
Surely "getting root" on the box would require the OS to actually behave in a logical way in response to a "CPU exploit".
Essentially the aim of such exploits is usually to get your code to be run with privilages it should not have had.
some examples: all modern operating systems use one copy of shared libraries in memory for all apps that use the library (not doing so would be very wastefull of both memory and cache). If a process can bypass the write protect on that memory it can force other processes to run its code some of those will be running as root.
If your code finds a way to flip the CPU into kernel mode without jumping into the OS then it has the run of all memory and hardware on the system. Once you have that it shouldn't be too hard to find the process tables and change your processes user ID to root.
ok it seems the wikipedia article has a link to the MS knowlagebase which says it was fixed for NT 4 (first by a hotfix and then rolled up into service pack 4) but not for windows 95. There is no information for more modern versions of windows there and the wikipedia article doesn't seem to link to any information on the status under linux.
usually an OS vendor wants to make thier OS run as reliablly as possible on as much hardware as possible. Presumablly that is why MS has shipped the patch for this issue and its a good reason for linux vendors to consider it too.
the thing is the "theory" that "god did it" cannot be tested because god can fake any evidence he wishes. It also cannot make any usefull predictions of future events or discoveries. In other words scientifically it is worthless.
the likes of newton and einstein may have been regarded as crackpots by some at the time but theier theories prevailed because they gave solid equations that fitted the facts way better than anything else that existed at the time. Darwins therory of evoloution can't give predictions that accurate but in many cases intermediate stages predicted to exist by evoloutionary theories have been discovered.
Afaict fibers used for this kind of purpose are generally plastic because its cheaper and easier to work with (communication fibers are glass because they need to be very low dispersion and low loss).
i suspect where the article said european it should have said "from the EU"
by the traditional definitions of the continents (iirc some mountain range) russia straddles the border between europe and aisa. IIRC most of its population is in europe but most of its landmass is in asia,
The important thing to notice is that since it's a DEBIT rather than a CREDIT card, you cannot use more money that what's available on you account (the bank _may_ allow the balance to be slightly negative).This is ALSO the situation with my VISA card - it's also a debit card in Denmark. are you sure about that?
I was under the impression that proper VISA debit cards (as apposed to visa electron) some transactions don't go through instantly with all merchants and therefore its possible to go into the red (or go over your overdafraft limit if you have one) and that was why VISA electron cards (which aren't accepted in anywhere near as many places as proper VISA debit cards at least here in the uk) exist for people the banks consider too risky to give a real VISA card to (kids and those with poor credit histories).
One could buy something off eBay with cash (just mail them the cash) - not necessarily the wisest thing to do, but possible. I've done it before in a pinch. I'm in the uk, the seller was in germany. I discovered after winning the auction (yes I know i should have read more carefully) that they didn't take paypal and the price of making a bank transfer was more than i was prepared to pay for such a small transaction (iirc it was a flat fee of over £10 for all transactions up to several thousand) .
There is a gotcha in the Nyquist theorem. The steep, brick wall roll-off filter at around 20KHz that you need for about 44,100 Hz sampling has a large phase shift well down into the upper audio range Sure but having a 44.1 KHz output sample rate doesn't mean you have to do the actual sampling at that rate
DSP brings us the power to do things that would be impossible in the analog domain. The fix for the phase shifting issue is to keep the analog anti-aliasing filter simple, sample at a much higher rate (say double). Then use a symetrical FIR filter (whose only phase affects are those of a pure time delay) then downsample to the standard bitrate (if you are clever you can combine the aforementioned steps and thereby halve the required multiply-accumulate rate). This is expensive though so only high end kit will do it this way.
hire someone! Sure there are people hired to deal with unhappy customers. How good a job they do is debatable but they undoubtablly are there.
If people knew the CEOs direct contact address they would use it to try and bypass the normal procedures in the hope of getting a more sympathetic ear than those whose job it is to be yelled at all day by unhappy customers. In the process they would overwhelm him with mail, of course he could have mail to his address handled by underlings but that would just turn it into another support address and make it no use for its primary purpose.
Despite being a forced upgrade on most Windoze platforms hardly a forced upgrade, i haven't installed it myself but iirc you have to allow "windows genuine advantage notifications" onto your system (something i'd rather not do even though i use legit windows, it just seems like another thing that could go wrong) and i think you have to agree to a specific license agreement for it as well.
and its not availble (at least without some cracking work) for windows versions other than XP SP2 and vista.
they keep putting out new versions of the standard C++ library. Code using different versions of that libary can't be loaded by the same process without risking crashes even if the library interfaces stick to plain C constructs. Worse they keep making the complier stricter so you can't just recompile stuff to get it to the same libstdc++ version.
The thing with orbit is you aren't just high up out of the atnosphere you also have considerable lateral velocity to get rid of. The normal way to do that is to use thrust to make an orbital adjustment that brings the veseels into the atnosphere and then dump the velocity by friction.
This works but requires a HUGE ammount of heat shieling. Far more than a simple suit could provide.
When the roaming charges payed on top of your normal charges are more than the network you are roaming on charges thier customers for the complete service something is wrong!
trouble is the only alternatives for users is to use some kind of intermediatory (either run by them or run by a third party) to route calls to many different numbers and carry arround a SIM card for every country they visit. Worse in some european countries apparently you need to be a local resident to buy a local SIM card legally.
NONE of the providers make thier roaming charges easy to find out, sure its probablly burried on thier websites somewhere but its going to stop the majority of people finding out until its too late and thats all thats needed to maintain the status quo.
It only takes one customer (or test buyer) to spot a counterfeit and provide information allowing the counterfieter to be traced.
Plain pirates who do nothing to disguise what they are selling as legit may do some damage but buisness customers are easilly scared away from them by the threat of audits, counterfieers OTOH can sell at a much higher price to buisness customers taking sales directly from MS.
of course if you include satalite or leased lines most of the world has a broadband option.
If you have high broadband availibility and low penatration then imo its a sign that the products your survey is counting are overpriced.
the phone lines/cable TV cables are already paid for by other services, the only reason for low traffic broadband to be expensive is that local monopolies often aren't properly regulated.
Paper spam wastes the environment. So does spam (through energy consumption; internet hardware has had to be significantly expanded to accomodate spam.) It's all bad. you could say the same about marketing in general, it uses rescources that could potentially be used for more productive things.
many slashdotters dislike marketing or see it as a "waste". However without it we would have little idea what products were availible. Manufacturers who are unable to find customers (whether direct customers or people who would resell thier product) wouldn't be able to sell thier products and so wouldn't manufacture anything.
I agree with the GP that the real problem with spam is that it is incrediablly cheap to the spammer. This means that the volume gets incredibbly high. If e-mail spammers had to pay paper mail like rates the volume would drop like a stone to a level where it wouldn't bother most people much just like paper junk mail doesn't.
discalimer, i'm in the uk things may be different in the USA.
At least in my experiance when poeople text they don't bother about spelling right or using punctuation or full forms of words. They abbriviate as much as possible.
i don't text much either but it does have its uses. Texts can be sent far more discreetly than making a phone call and the recipiant can pick them up at thier leisure (yes there is voicemail but this often costs money to retrive and is generally a lot more hassle for the recipiant than a text, the combination of theese factors mean not everyone enables it). Also if the signal is poor texts often have a much better chance of getting through.
and i'd imagine mobile e-mail has much the same interface requirements as texting with the benifits of being much cheaper and able to contact anyone.
How often does the average user click on an HTML link OUTSIDE of a web browser? Occasionally, but not very often. maybe i'm weired but i tend to click links in my mail app on a regular basis.
apples hardware range is relevant to those considering OS-X because if you want to run OS-X without breaking both the license agreement and technical protective measures you have to run it on apple hardware.
and apples midrange hardware range is really the opposite of what the likes of hardocp users would want. The midrange stuff (the various imacs) has built in monitors making it unsuitable for those who use kvm switches to run multiple machines and who already have a servicable keyboard monitor and mouse. None of it except the very high end (mac pro and xserve both of which are very nice machines but you pay a lot for them) has upgradable graphics or room to add extra drives.
apples desktop models in summary mini: low cpu power, laptop hard drive (read: slow compared to what you will find in PC desktops and you CANNOT get a drive over 200 gigs) of course you can chain on drives externally but from what i can gather usb and firewire drives are nearlly always slower than internal drives. Integrated graphics. imac: the higher end models do seem to have desktop hard drives and decent CPU and graphics specs. But you still cant add extra hard drives or upgrade the graphics and the built in monitor is a major downside to those of us who like to keep thier old machine arround on a kvm switch (if anyone from apple is reading this building a KVM switch into the imac would be a great idea. mac pro: nice hardware and expandable but expensive
in summary if apple has hardware within its limited range that fits what you want without being overkill then great. If not then it is a major down point for OS-X (unless you are prepared to run a cracked version).

All operating systems at the time quickly implemented a workaround for the bug.
Neither of the sources you give backs up that statement.
why shouldn't it?
