no it doesn't need to be suid root, it just needs to be hostile towards the user it is being run as.
e.g. if i create a JPG myself and run it through an image viewer running as me then there is no problem (as anything i could have done through an exploit in the image viewer i could have done anyway).
but if i get a JPG from elsewhere (another user on the system, removable media etc) and it contains data that triggers an exploit in my image viewer in order to perform some action as me then it is most certainly a secuirty concern.
right i can see why they can't distribute it. the system should pop up a box saying that it needs access to the windows driver to extract and install the firmware. not leave the users guessing and searching forums.
that is the sort of thing that distros need to do if they wan't real sucess on the desktop. Being the underdog means its up to you to keep your hardware support (and by support i mean hardware that can be used WITHOUT googling for and following a complex howto) as close to the market leader as possible.
player: free version for desktop users, reasonablly optimised graphics but very little support for anything else
workstation: high end version for desktop users, has features targeted at developers (low level debugging) and product demo teams (bringing up a whole network of vms as one unit)
server: free version intended for server use, graphics subsystem designed for remote control and not exactly fast, uses a host OS (often undesirable in a server environment for preformance and stability) and (iirc) lacks vmotion.
unfortunately i belive at least in the bnetd case that wasn't how the US courts saw it, in many other countries it still lies untested but if verdicts start going against the click-through EULAs you can bet that there will be laws/treaties pushed through to change it pretty quick.
sure you can, electricity distributors do it all the time you just have to make sure you use insulated tools and only cut one core at a time. you can also i belive get ceramic blades though if the cable is fine stranded this won't gaurantee a shortless cut.
plastics are mostly made from hydrocarbons, currently the cheapest way to derive theese is generally from oil but there are many other sources possible.
also oil won't "run out" as such, it will just reach the point where it is not viable as a source of energy (e.g. where you need more energy to extract the oil than you get from burning it).
sooner or later the world is going to have to bite the bullet and get serious about nuclear again with modern efficiant breeder reactors and hopefully eventually fusion. Once that is done we will have all the energy we need to extract hydrocarbons from even the worst sources. Unfortunately the anti-nuclear lobby is very strong and the terrible effects (both from global warming and from ever increasing energy costs) of not going nuclear won't hit the general public until its too late.
the trick with plastics and UV is to add a pigment (carbon is often used at least with outdoor electical cables) that absorbs a lot of UV light and therefore prevents the bulk of the plastic from being effected by it.
People are running servers with Via C3 processors? just because a box's primary job is providing a service over a network (rather than supporting a local user) doesn't nessacerally mean it needs to be fast.
presumablly thier assumption is that people will eventually forget to continue ringing up, especially if thier financial worries pass by and they get busy with a new job.
i tried this once on the university system (somehow everything on my user account except my public webspace dir was deleted when i logged out one time, i still have no idea why) and there didn't seem any way to recover a deleted folder without a pretty high level of access on the server (deleted files in the root of my user area was no problem using my own account).
P.S. i did eventually get the folders back but it took the universities central IT support weeks to get it done (i don't know if they managed to salvage the folders or if they had to restore them from a backup). lukilly my tutor accepted the reason for a very late lab report.
If your distro was bright enough to have a separate home partion, the above steps are not needed. Just use the old partition with the new distro. Applications and settings are not hard to get anymore. In a pinch, just give them Mepis and be done with it. If it runs off the CD, it will run on the hard drive and installation takes about 20 minutes.
btw there is nothing to stop you deleting everything except/home from a partition then moving/home's content to the root dir and then using that partition (possiblly after resizing) as your new/home
The thing is, if you really want to be legit, you have to buy retail. but people don't really wan't to be legit, they just wan't to do enough to convince enforcement (whether human or automated) that a machine is legit.
But you only get that if you have one of a few specific name brands to begin with, which probably means you've got a legit copy of Windows. Hence, it wouldn't apply to this situation. or the whole reason they are on corp is the first place is frustration with the crappy big brand oem installation media.
IE: Laws don't prevent me from mugging you or murdering you. they don't the first time but once your in that prison cell you aren't going to be mugging or murdering any more members of the general public for some time and even the first time the fear you mention will stop many people, you can't have fear of imprisonment without actually locking some people up.
now of course you could have imprisonment without laws but that would be even more open to abuse.
ok but those are just as unpaletable to the RIAA as un-drm'd MP3.
and if you are going to sell un-drm'd music to the masses may as well do it in the de-facto standard format
the RIAA is in a bind, they don't want to sell online without drm but at the same time they don't like apples stranglehold on the online music market, which is largely caused by them being the only ones who can sell licensed major label music online to IPOD owners.
afaict he was reffering to the length used when copyright was first introduced in the USA. Since then the US has had a long string of extentions brining copyright up to as long as the longest in the civilised world.
ok well for 1GHZ first with a standard PC processor running at its rated speed without having a freezer unit strapped on then.
as for 64 bit both the alpha and the itanic suffered from not being PC processors more specifically:
in the case of the alpha while there was code to make it run i386 apps and i belive it did perform rather well (at least in its later days) you were still forced to run a special version of NT that home users would have almost certainly found unacceptable.
in the case of the itanic it could run i386 apps directly but performance was abysmal, again you wouldn't have dared to put it in a consumer machine with full 64 bit software a long way off for most uses.
AMD64 chips OTOH allowed manufacturers to advertise the 64 bit processor while still shipping the standard 32 bit os and thus not unduly pissing off the customers once they got it.
1: anyone who has legitimate reason to enter will have a card many people (especially kids, homeless who might try to use it as a shelter etc) who are likely to be unwelcome won't. cutting down the number of bad guys and not the good guys is a win even if you don't stop every bad guy. 2: you could possiblly design it to log cards read for the purpose of tracking down troublemakers (if that is they use a bank card and not something else that happens to satisfy it). Even if you don't do so troublemakers don't know if you are doing so or not.
as for a fake unit if the card reader didn't actually open/unlock the door people would spot it pretty quick. once you make it complex enough to open the door its probablly just as easy to use a real reader (they aren't that expensive)
there have been 2 full loss accidents in just over 100 missions.
going on that data the risk per mission sounds quite high to me. certainly worse than driving to the airport and taking a flight.
now the risk per mile is very low but thats mainly a result of the insane number of miles done in the relatively safe LEO environment, its launches and landings that are dangerous (for any spaceship not just the shuttle).

I may be delusional, but I thought there was a way years ago via loadlin.exe and something like umsdos filesystems under linux, and booting and sharing between the two was theoretically possible. I never tried it, but I vaguely remember such a thing. windows is a moving target.
with win9x you could happilly use loadlin in your autoexec.bat and umsdos to run linux with no repartitioning and no touching special disk sectors.

most new pcs are now using NTFS (for good reasons, it supports permissions and larger individual files both of which were annoying limitations of fat). Unfortunately this makes it a little trickier for linux to share windows's space. The UMSDOS approach has never been done for NTFS (probablly due to a lack of an adequate NTFS driver, image files are another option (and have been supported on NTFS partitions for a while though all creation and resizing of the image had to be done from windows or using something like captive) but are a bit restrictive (you have to manually set asside a lump of hdd for linux). Full partitioning is even more restrictive (partitions can change ids as you add and remove them and any reallocation means at least two seperate resize operations one of which will likely involve signficant time spent moving data).
