using post for every link would be crazy (you'd have to use form buttons for every link) and would cause problems for people linking to your site, so you either have to put information on the url or in cookies.
the only other option i can think of is http auth but that gives an annoying popup in most browsers and limits you to a simple username/password for the login.
provided you haven't changed anything that changes the linux image itself and only changed modules you should be able to load the new modules without rebooting.
but when your working below the filesystem level (and as i said if they were building in understanding of the filesystem it would almost certainly be obvious to anyone who formatted one in anything other than its default configuration) how do you know what blocks are unused without having extra blocks above those you make visible to the host?
I can see solid state drives taking over hard drives in the future i don't see that happening unless increases in hdd size and software bloat stop. If you only wan't to run 486 era software (windows 95 office 97 some small games etc) theres nothing stopping you running off a CF card now without paying a huge ammount. but buying enough to support current bloatware is prohibitively expensive. I don't see how this is likely to change sure the cost per megabyte of flash will go down but software bloat will probablly keep going up.
i thought they used extra non user accessible space for the wear leveling. If they were really building in understanding of filesystems like you suggest it would be obvious to anyone using an alternate filesystem.
no need for the single option as you aren't about to run init anyway.

oh yeah not having physical access (or a serial console) means you have to be VERY carefull when touching certain parts of the config. This particular example can be avoided by having another way to get root but there are many others such as iptables, sshd etc
btw you don't need a livecd if you can get to the bootloader prompts, just use init=/bin/bash on the kernel command line and the box will drop straight into a shell. Type exec/sbin/init when you are done to resume normal boot.

i guess it depends on WHY you are revoking the admins privilages in the first place. if your just moving them to another group with no hard feelings then i suppose you could argue this. If your getting rid of them for misconduct you have to seriously consider that they may have installed a rootkit.
It does not have to be a list. It can be a flag against the persons account, which is as personal as their other personal details.
e.g. one database query away from a list. Its a case of do we wan't such private details that aren't really nessacery for ISP operation stored by our ISP in an easilly queriable (and probablly quite widely spread through the ISP to actually implement the filtering) fassion
bandwidth we can improve fairly easilly by using more power, better antennas etc. Latency is pretty much fixed for radio and free space optical communications unless there is some REALLY radical discovery (e.g. on a similar level to perpetual motion).
windows shows it as being on ISA whether it really is is a different matter. If the stuff is on the motherboard and has a fixed address by convention is there really any point in exposing a pci/plug and play interface for it?
even though we are deprived of head-movement based analysis while wearing headsets i wonder how hard it would be to make headphones that responded to head movement amd fed the info back to a controller....
i'd imagine it would depend on the bath. If the bath and the waste plumbing plastic you'd probablly get away with it. The bath water would oscilate in potential but you would just ride up and down with it and i can't imagine there would be any significant current outside the toasters case.
now if there are other paths out of the bath for electricity thats when things could really get nasty especially if the toaster didn't have an earthed metal case.
yeah unfortunately linux has problems with certain hardware types
off the bat theese are 3D graphics Software modems (winmodems) Wireless NICs
of those the second one is likely to be a big problem if using donated computers and trying to get them on the net with linux over dialup. hardware modems are pretty expensive.
Sure there are drivers availible but they are generally not Free (as in GPL) and sometimes not free (as in beer). and they can require considerable extra setup work.
from an operational point of view windows is probablly better if you never plan to see theese pcs again but linux may be easier if you have to manage it yourself.
then theres the licensing issue, if you use the original windows licenses they will all be runnning different versions with all the support fun that will bring. Theres also the issue that many machines are likely to be lacking media/licenses. Relicensing all the machines is liable to get expensive fast
i'm not aware of any type of motor that simply locks up when no power is applied. the most obvious is one with a worm gear drive (often seen inside low rpm gearmotors)
to get a dangerous current through the body without going to implanted electrodes you need a high enough voltage. 12V simply isn't sufficiant to do this (note however that some parts of a cars electric system are at far more than 12V the ignition system contains a step up transformer).
static shocks are high voltage and high current but very short duration and so do not have enough total energy to do any real damage.
i think electric fences also generally work on the short duration shock principle (it gives plenty of pain with little risk of harm). its possible the ones in the USSR were rather cruder and/or set higher than the ones we see in the west though)
well to "fix" activex would require major changes at the OS level to allow safely running untrusted native code.
personally i think the best option for activex is to leave it completely disabled by default with a hidden setting somewhere for those corps that bought into it (maybe because they didn't have a proper app deployment setup or whatever) to enable it for a few spefic sites. Its most certainly totally inappropriate for the open web.
nope you had a 1 megabyte address space broken down into 64K overlapping 64K segments giving a segment start every 16 bytes.
i'm not sure just how much conventional memory you could get free under dos but i gather if you loaded drivers into UMBs and dos into the high memory area (the first 64K minus 16 bytes of XMS accessible due to a design glitch) you could free up most of it.
iirc lg did release details of an emergency flash mode after that incident (iirc it involved fitting the master/slave select jumper sideways) so the drives could be recovered.
The world is set in a futuristic, post apocalyptic "Mad Max" world. if youre going through a war torn zone and start seeing pristene unweathered billboards for Pepsi, it's going to look fishy.
one interesting question is do the billboards need to look pristine to have an affect or would billboards for pepsi that looked like they would post apocolypse (weathering random damage etc) be effective.
it seems mini-itx.com are stocking a pin headers only version of the epia N. i haven't seen any in the mini-itx size though.
btw if your building into a system you don't have to use those bulky hoods on your D connectors. Just bend the wires in the direction you wan't and tape em up to add a bit of regidity.
That's what happens in UNIX when an application doesn't "think of the multiple sessions in one account". To get the Windows behaviour you have to deliberately deal with multiple instances and change your behaviour.
as someone who has coded for windows passing input to the existing instance of an app isn't the default behaviour on windows either. I can't remember if windows has an api that makes it easy though or if you have to use a fairly generic method.

afaict modern disk like flash has controller chips that perform wear leveling functions to basically eliminate this issue.
