You still have effective brakes if ABS is switched off. In fact, you have brakes which are MORE effective in the hands of a very competent driver.
ABS systems actually release the brakes when lock is detected and then progressively let go of this release until lock is again found, etc etc. The effect comes close to optimum braking (good for people who don't know what to do with locked brakes or don't have the response time to correct), but cannot match the braking skill of a good driver who is not hampered by ABS.
My point is, impact of ABS loss depends on driver skill. A good driver would react to it before even realising that the ABS is not working.
A friend of mine purchased a Mazda second hand and had it for years before realising that the ABS was not working. It was just a blown fuse. For all he knows, the ABS was in this state since the day he bought it.
Often, with bank robberies, the driver is chosen based on how well they drive.
I hope OpenBSD has gotten easier to use and install. Its not for the faint of heard.
Easier to use? Learn it and you will never look back. Seriously. Read the FAQ, man afterboot, there are some OpenBSD specific books coming out... I am pretty much finished with Linux (although Gentoo interests me for media/MAME console), I'm only keeping up with it for employment reasons.
Easier to install? OK, if you're not going to use the whole disk, then it can be trickier than Linux to install at first, but besides that, it is SUPER easy. Are you afraid of it being all text? That is actually a blessing. I do most of my OpenBSD installs via serial port. Most of my OpenBSD servers have nothing but power, ethernet and null modem cables plugged in. No keyboard, mouse or video card and I really like it like this. KVM for me consists of simple serial port switches.
If I trusted OpenSSH enough, I wouldn't even rely on the serial console. The major proactive improvements to security they've been making lately will probably cause me to re-enable ssh soon though.
Last time I used it (2.something) post install configuration was non existant. it was like: "Here's some iron ore, build a truck" I can vi ascii files, but getting X running was an absolute chore, it was reminiscent of Slackware back in the 1.4 kernel days.
As Mr evilviper points out, it's really easy to get X going.
But the average MCSE is not a good NT administrator.
I think "every good NT|foo Administrator is invariably always also a good Unix guru" makes sense to me, since the good NT admins I've known, I would place in the top 2% of NT admins. Meaning the average is very poor and good admins (NT or Unix, they're usually the same person) are VERY hard to find.
Put the average MSCE in front of a terminal window and he'll break the F1 key.
For sure. He won't be able to get past the whole back/forward slash thing.
I much prefer spending my weekends with my gf and/or friends.
Some sys admins love their work too much I guess. I took care of a stock exchange backup network, worked crazy hours, usually 6 days a week, and actually loved it...
until the politics changed and realistic, learned management who'd worked their way up in the industry, were replaced with some completely clueless non-IT management who managed to cause almost every IT staff member to leave within months (some of the most incredibly gifted IT people I've ever met, allowed to go for a few bucks an hour).
Systems let me down far less often than people do, which is why I prefer to spend my time hacking than drinking on Friday nights.
I have a gf now, but I *really* miss the times when I could go for hours in front of a machine (and achieve plenty) without being whined at.
If I gave up my gf for the old life, you'd probably say "get a life", but some people enjoy "having no life".
PS, my original post was merely poking fun at what constitutes pretty much every sys admin I know (they always come back after drinks to "do stuff" with their babies, almost secretly, as if embarassed about actually loving their work).
"I'm going to release these at 7pm on Friday, so that sysadmins don't know about this and can't do anything about this til Monday morning" (paraphrased).
What I'd like to know, is what real sys admin is NOT glued to multiple consoles at 7pm on a Friday?
That's about the start of the week when real work can get done!
Seriusly I bought my ibook and i'm thinking that my next laptop will be a IBM with XP.
Thinkpad's are really nice, I love the keyboard especially. But then I love my iBook too (I've got both). But I prefer to run OpenBSD on both of my notebooks.
I think it would be nice if Apple re-arranged their version numbering so that "major chargable upgrades" came once every 2 years and everything in between was a free online update. I was about to purchase Jaguar about 2 weeks ago, I'm glad the local Apple dealer was shut that Sunday, because this news would have annoyed me.
But, just nice, they can charge if they want and we are free to decide whether we will buy into it or not. MS is hardly any less money hungry.
I think that Apple's OS just keeps getting better and better as time goes on, which I can't really say about MS OS'. I'm sticking with Windows 2000 Pro for my Wintel needs, probably until they completely end-of-life it, at which time I'll hopefully have been able to rid myself of any need of Windows for good.

Disgruntled and poor ex-Soviets are more of a concern than some two-bit Iraqi.
If the Soviets are so poor, shouldn't they be spending their money on, oh, I dunno, SURVIVAL, rather than organizing a strike on the US? And if you mean all those little nations, please, I think they'd rather fix the troubles they have before attempting to piss off the largest armed forces in the world. Unless they're extremely naive.
I think he's refering to the problem that there are/were desperately poor individual Soviets working in nuclear science (often unpaid or not paid enough to survive), pushed to the point of stealing and selling substances that could be used to make nukes.
Disgruntled or not, desperate people do desperate things.
And just think, within 24 hours, this factor will be playing out in a much scarier scenario, but it will be the interface between chair and control column.
Then again, I guess Nukes receive target info via keyboard...
No, I've pretty much decided I'm not going to install OpenBSD until the next format.
Ahh, "the next format", you must be a Microsoft user! I remember the days where the biggest performance boost you could give a Wintel box was to reformat and reinstall once every 6-12 months.
I have four on this hard drive and not a single problem in the year they have been sharing it for.
The problem of one OS overwriting disk space of another on the same disk is possible, but a user doing this out of merely being human is likely.
I've booted between 7 different OS across two disks, trying to learn the differences between various OS and not had any trouble outside of the fact that some OS are finicky about only booting off the first disk and others finicky about multi-booting at all. But just because I had no baddly behaving OS doesn't mean it cannot happen.
But then... a few months ago, while installing my favorite OS (OpenBSD since 2.5) I managed to wipe out my Win2kPro installation. It came down to a mistake I made with OpenBSD's "fdisk". I think that is where the real danger is.
The picture in the article is just one of a bike as an example of what the motor *could* fit onto.
No it isn't. Look closer. That's not a drum brake on the front wheel. Can you not see the heatsink of the 2 stroke engine to the left of the large central portion of the front wheel?
battery-powered bicycles are not the answer to the world's traffic dilemmas because the problem is that it takes about 377 lbs of lead-acid batteries to equal the energy stored in a pound of gasoline.
Wow, way to make an argument. Choose the heaviest oldest battery technology there is to defend the usage of one of the noisiest, dirtiest combustion engines that exists!
Steve Katsaros is giving hemself a big pat on the back, but he's employing an engine that would gain huge benefits out of variable gearing, yet is not using the variable gearing that is on practically every bicycle out there!
What I would like to know is, what the hell part of this brilliant design received a patent? If this were part of a Uni student designed project, I imagine this would constitute a failure.
Batteries have evolved well past lead-acid and combustion engines well past 2 stroke, for Christs sake.
Looking at the picture, it seems that the engine is lying on it's side, facing into the wind.
This will give poor cooling performance for the heatsink, which should have air flowing through the fins, not around and with the engine on it's side, the piston will wear one side of the cylinder more, due to gravity, leading to an even more inefficient, smelly 2 stroke. Just like an old boxer engine that leaks oil.
I've been thinking about building some electric motor assistance to my mountain bike, with an array of rechargable batteries within the larger triangle of the frame and perhaps a solar panel for more prolonged usage away from AC outlets.
I remember when THG was a "3Dfx site", back when dual Voodoo2's rained supreme and 3Dfx "AGP" cards were merely AGP cards operating full time in PCI mode.
He claimed that AGP held NO ADVANTAGE over PCI and then got some "expert" to give reasons why this was the case.
The moron actually had an S3 developed Q2 benchmark map that used very large textures that showed an AGP Matrox G200 running MANY MANY TIMES faster than the dual PCI Voodoo2 setup. This was due to the fact that the textures were larger than any of the cards could fully cache and thus must rely on their PCI or AGP buses... thus the SLOW G200 with the fast AGP bus absolutely creamed the fast Voodoo2's with the SLOW PCI bus.
But of course he never pointed this fact out.
Then suddenly his site became an "official nVidia review site" and a most incredible bias phase change occured. 180 degrees in fact.
THG spins things like no other. Tom is a filthy 2 bit WHORE.
They [cough] "reviewed" [splatter] some PSU's recently, with some dummy loads and multimeters, with some supposed "experts", who did not even measure ripple (I would hold voltage drop and ripple under load as the highest priorities for testing for good PSU design)!!!
So, ask yourself: would you still be running a 1GHz P3?
I'm still running a P3 500 and a G3 300 (128MB), Win2kPro and OSX 10.1.4 respectively, along with a P200 OpenBSD server and P133 OpenBSD firewall.
I get most joy out of using OSX (even on the G3 iBook) and OpenBSD on my various machines.
For me, the overall interface experience matters more than the speed and I'm over wanting the fastest thing around (back when I first started overclocking, it required soldering). If I were a mad gamer, renderer or whatever, I might care. I can actually put up with OSX performance on a G3 because OSX is the ducks guts as far as I'm concerned.
Don't get me wrong, I will probably get a new 970 based Apple after the first few models are released, but my current computers will still serve me (performance wise) until then an upgrade would merely be a luxury for me that I would only jump to if the price was very good.
Based on a sample size of ONE you come to the conclusion that Yamaha burners suck?

Got sarcasm? (BTW, the figures I give for my Yammy are true.)
If ur answer is to just record ur random noise once and then make a copy of the OTP which is then passed on "securely" to the point of decryption then why not just send the data along this same route.
There can be times when sending ciphertext is not a critical requirement and sending a OTP to "the other end" is easy enough to achieve. Sending large OTP's for future indexed reference (areas of OTP only used once) for ciphertext transmissions.
Having large OTP's on either end in preparation for the need of strong ciphertexts?
It's a little surprising to me that we have not heard anything about a Shuttle equivalent of an airliner's black box. Surely such a thing should exist on the Shuttle, where risk of a catastrophe is much higher, and measures ought to be taken to make sure such things do not happen again.
Hell, trains in Australia use black box recorders. The shuttles were using TASCAM recording equipment back in the early days and I would highly doubt that the shuttle does not have a black box. With NASA being very military in operation, it wouldn't surprise me if they had MANY black boxes distributed around the shuttle. Relying on comms back to Earth for this type of thing is laughable. I'm sure that Earth based telemetry would be used as a backup and to help ground based crew to resolve potential issues though.
Having worked with USN equipment and some NASA methodologies, if they really don't have anything like a black box within the space shuttle, then they've lost a huge amount of my respect and I'd have to wonder what the hell has happened to them.
Right now we have several media "experts" offering their opinions.
Am I the only person who noticed the enormous crack in the wing when they were showing pictures of the dented wing on TV?
Traveling through space at 20,000 kph, this crack would pose little problem, but then when you hit atmosphere at that speed, whats stopping that crack from violently ripping right open and exposing parts of the wing to extreme heat and forces that they were never designed to be exposed to.
Hell, 747's have had sections of fuselage ripped off at closer to 1,000 kph.
I realise that people on TV with opinions could be sarcastically labeled as "experts", but don't forget, NASA has made a LOT of fuck ups through the years. 2 space shuttles, many MANY botched satelites that just disappear due to ridiculous reasons like mixing imperial measurements with metric and then there's the hubble, ruined due to a single fleck of black paint missing from a null corrector in some calibration equipment.
There's more to being an expert than being a hyper geek. And these NASA "experts" got themselves into this trouble in the first place.
but I _do_ have a problem with people not minding their own business.
Knowing the rationale can lead the tech to explain why it's not correct. Without it, next time she might bake it at half the temp for half the time, when really, she should have just seen a tech to begin with.

it may very well be possible for a CISC instruction to perform the same computation as several RISC instructions in fewer clock cycles.
Can't argue with that.
fewer instructions have to be fetched and decoded to do the same action. CISC has the potential to be faster thats why I said theoretically.
Which is why the memory bandwidth of Macs depresses me. I know that this is especially a bottleneck for RISC.
But given the real world performance of high end RISC systems it looks like the theories don't translate very dramatically or most RISC systems have high bandwidth to memory.
Assuming it does not get broken down into a bunch of RISC like microinstructions
I would have thought that CISC breaking down to RISC within the CPU would be an absolute god send. Reduced memory bandwidth requirements AND potential high performance pipelining. As I've said before, I think Intels methods for retaining performance and legacy compatibility is pretty impressive.
