maybe recently processors have been getting lower power but i've seen P166 systems running fine with a broken fan and tiny heatsink! you try doing that with any recent cpu.
I get the feeling we've kind of reached the limit on how much power a CPU can safely handle though.
it would greatly surprise me if they didn't. The first job a switching PSU has to do is turn the incoming AC into DC. Doing this half wave whilst possible would mean larger smoothing components would be needed elsewhere.
and a full wave rectifier WILL turn AC into DC its just that it would be pulsating DC which really isn't desirable for electronics.
yeah he has hardly tested this thing at all probablly because its a computer orientated site and he doesn't have the kit (it sounds like he doesn't even have a scope let alone the amount of kit you would need to build a proper psu test rig)
also to test a psu model properly imo you have to destroy a few of them (for example plugging the psu into a variac and then turning up the voltage until it blows whilst watching the output voltages) in order to determine how the psu behaves when it is destroyed (ie does it fail gracefully or does it fail in a way that will destory your pc?).
also he states that everyone would wan't a main ATX cable. sure most people might but some may wan't to use the PSU for non-pc perposes or as a second PSU in a large PC setup.
theres combined cycle gas turbines which are more efficiant but still fossil fuel based and run on natural gas which i belive is expensive in the usa.
i didn't think the usa cared about greenhouse emmisions anyway and afaict they've got pretty damn large coal reserves so i don't expect anything much to change thier for a while
finally there are nuclear plants but we effectively castrated those by making them carefully store anything that is even the slightest bit radioactive and by scaring the public with early unsafe designs (the fact that early nuclear stuff was basically weapons research with much lower safety standards probablly didn't help either iirc both windscale and chenobl had at least partially military goals) unlike fossil fuel plants which dump thier main waste product straight into the air.
UPDATE - Like all vandalised Gatsos in the area it was replaced shortly afterwards but the new camera has since been blown up using dynamite, see below.
one thing i think is an issue is its hard to make exploits that work against a range of kernels as offsets etc change. but with some effort most of them could be adapted to other kernels which have the bug but need slightly different numbers to exploit it.
its not like the ms world were there are very few builds all released by ms. with linux anyone can make thier own build and its very likely that an exploit will need tweaking for each one.
true debian doesn't release as often as some other distros but when they do support for thier previous release dissapears relatively quickly (iirc generally about a year or two)
also debian woody (current stable) is only old when compared to the ultra-rapid release cycles of other linux distros. Its actually newer than winxp.
sure you could distribute text online in the form of images but that would be horriblly inefficiant
so we need standard ways of giving each charactor a reference computers can deal with and unicode (usually encoded into a utf-8 bytestream) has become the standard means of doing this.
i think many opensource apps are built as clones of other apps but i think the same applies to many propietry apps too
big new inventions are rare most of the time people work on copying each other and incremental improvements.

yeah and thats the problem
the publically traded company is a way that people can avoid taking personal resposibility for the way thier money is used and instead put it in the hands of someone whoose job it is to make the most money possible by any means nessacery regardless of ethics.
whats worse the market system compels those people who run the buisnesses to think about short term profits over long term viability and reputation.
provided compilers are availible and you take care its perfectly possible to write reasonablly portable apps in most langauges
the trick is always to keep parts that need to interact with the os seperate from parts that don't its much easier to do this for stuff like server daemons than it is for gui apps though. Its very hard to do a good gui cross platform (and by good i mean good enough that people won't consider your app to be a crude port like they do with say gtk apps on win32)
for the vast majority of smaller apps there is little gain to amd64 (a slight performance gain but little else)
those few apps that actually need as much memory as they can get will probablly move fairly quickly. The rest will probablly stay win32 for a long time.
the bigger problem with amd64 imo is the dropping of support for 16 bit apps such as the old microsoft entertainment pack.
yeah that unfortunately means the stores still have to burn the cdrs which could be quite time consuming.
what mozilla really needs is the ability to update without re-downloading everything. Its kind of a kick in the teeth to sell users a boxed copy of a peice of free software only to have them have to download the whole thing again soon after to get a security patch.

an inadequate or low quality PSU may well destory your system BUT i see no evidence in the "review" that that PSU is high quality.
to test a PSU properly is NOT a job for a computer review site and will REQUIRE multiple samples to allow different failure modes to be tested.
it would greatly surprise me if they didn't. The first job a switching PSU has to do is turn the incoming AC into DC. Doing this half wave whilst possible would mean larger smoothing components would be needed elsewhere.

mods on crack again?
;)
the parent post is a JOKE it should be modded as FUNNY!
its like saying you'd rather be using tubes than transistors to build your psu
diodes have a junction with large peices of material on either side (either metal and semiconductor or semiconductor and semiconductor)
so with a big diode unless you physically melt the thing you aren't going to do it that much damage
transistors on the other hand tend to involve thin layers (of semiconductors in a BJT or insulator in a MOSFET) which are easilly damaged or destroyed

wasn't that the time when most machines had thier own basic that was very different from anyone elses.
the bbc micro certainly didn't use microsoft basic and i don't think its predecessor the acorn atom did either.
hmm been to a big computer market lately theres loads of people modding ps2s (and yes i am in the uk)
;)
mind you they sell warez fairly openly at those places too
just because something is illigal (under what laws btw) doesn't stop people doing it.
not really

or simply put a gun to your head and make you open it?
imo the best eay is to keep important data live on hdd and only use optical media for backup/disaster recovery.
then every so often you just copy it to your new hdd which you buy anyway for space reasons.
every conversion between lossy formats throws away quality. avoid them unless you are really tight for disk space.
sure you could distribute text online in the form of images but that would be horriblly inefficiant
so we need standard ways of giving each charactor a reference computers can deal with and unicode (usually encoded into a utf-8 bytestream) has become the standard means of doing this.
so they just need to take a spare set of clothes when they do the kidnapping?
because a Firebird project already existed (OSS database)

iirc the firebird database ALSO used to be called phoenix....
i wonder what the next oss project to be called phoenix will end up being called
