Yeah I agree it's a big waste of time to rewrite and redraw stuff that's already written and drawn.
They should just put the lectures up on youtube (or elsewhere):
That makes things even more efficient in other ways - since students have a better idea of whether they might like the course or not, before they enroll for it, pay lots of $$$$ etc. Or even whether they can understand the lecturer's accent;).
Clearview doesn't have to figure out whether the entire program is correct. It just tries to fix what's known to be incorrect (and presumably whether it falls into the subset of bugs it knows how to fix).
The sort of "correctness" and "incorrectness" for many security problems are typically "stupid mistakes" nothing very sophisticated.
You're taking too much of the "Ivory Tower Computer Science" view on this. Car analogy - Clearview isn't figuring out whether the whole car is perfect (in the real world it's 100% likely to be imperfect anyway;) ), all it does is help detect and fix the holes in the exterior. It doesn't have to perfectly fix stuff.
FWIW I've already manually fixed programs without having the source, and managed to get a program to do stuff the manufacturer said the program can't do;). I've also fixed a TCL program stored in an oracle database by hexediting the oracle DB file, but since that was TCL it doesn't count as "without the source"...
Just because you can't make it perfect doesn't mean you can't make it work better.
Difference is in democratic countries, voters can vote out the government if they decide "enough is enough".
If voters keep voting back in governments that don't obey their own laws it's the voters own fault/choice.
Laugh all you want, but if voters can't even do voting "right", what are the odds that the same voters would be able to consistently and regularly vote with their wallets in order to send a clear message to companies? And it's harder if the companies have achieved a monopoly or an oligopoly.
There's a benefit of having the corporations run most stuff - the voters can then sit on butts and blame everyone else but themselves.
I've seen too many bad drivers to want to ride a motorcycle on a daily basis.
Yes, in many cases you can figure out what they are about to do. But the "mind reading" doesn't work so well when the idiot himself doesn't know what he wants to do till the last moment ("Oh, wait is that the exit? SWERVE! No it isn't, SWERVE-BACK!").
I've seen that somewhat graphic video that is supposedly for discouraging drivers from speeding and make them drive more carefully, but all I get from watching the video is pedestrians and motorcyclists better be more careful and aware that there are crappy drivers out there who have a significant chance of killing or maiming you, especially if you aren't prepared for them.
I believe the latitude models are supposed to be models which Dell will make available to sell for more years. This is useful for large businesses where you want to standardize on stuff to make things more manageable - drivers, install images etc.

The vostro appears to be the "cheap and ugly" range.
Seriously though, I've heard of illegal casinos where the physical roulette wheel is in one country and the gambler is in another country (where gambling is illegal or requires a license- so if "stuff happens" they just switch things off and there's not so much evidence or things to confiscate). To give confidence to the gambler that it's not rigged they have a TV in the background showing the latest news or something. It sure isn't a newspaper.
Of course nowadays modern technology can add customized ads on the sides of soccer fields for live telecasts, and certainly can add live TV to a rigged video...
Somehow millions of people still trust gmail with their data.
And so many are keen on cloud computing.
I have no access to the source code of my HDD, and I don't care as long as it works as expected and keeps working for long enough. I have no access to the "source code" of my CPU either. So what? I wouldn't even be able to debug it even if I had it, or fix my CPU.
Same goes for an SSD. For now I don't think they're cheap and reliable enough for me. But maybe next year or the year after.
Actually some first gen products can be pretty good quality. I suspect it's when the manufacturer can charge more and they don't know which corners they can safely cut, so they overbuild the product a bit. If they get lucky (no major flaws/bugs) you could end up with something quality that lasts.
Later on they figure out what corners they can cut, so the stuff doesn't last way past warranty:).
Truth is, there's not much point building some stuff to last that long. For example if most of your CD writers built in in 2001 last 15 years, they'd be way obsolete before they died - they won't be able to read DVDs or Bluray or whatever. They'd outlast the PCs they're used in but the motherboards in 2012 might not have PATA interfaces...
A "golden" first gen is rare though. So I thank all of you who buy bleeding edge stuff and bleed for the rest of us.
Here's hoping the good cheap 3rd/4th gen SSDs come soon;).
Anyone remember how long it took before PC CDROM drives had buffer underrun protection?
I considered CD writers before that point not fit for general use. I'm actually amazed people bought those drives. No other choice I guess.
Interestingly my old LiteOn with BURNProof (one of the first drives with that tech) is still working after all these years. But the amount I paid for it can buy me 10 or more DVD writers today (but these modern DVD burners so far only seem to last 1.5 to 2 years;) ).
> A properly configured firewall is the real solution.
Uh, read the original post again, you're missing the point. Even if those "NAT routers" aren't real firewalls, they ARE and HAVE BEEN protecting those windows machines from remote network attacks.
So much so that nowadays most attacks on windows are by exploiting application bugs (browser/PDF/flash) or by exploiting user ignorance (install this AV software/Windows Update now!).
Yes in theory an attacker with access to the ISP's adjacent network (directly or via BGP exploits) can get past the NAT device, but in practice that hardly ever happens.
Unless I misunderstand the link, for the people who experience the placebo effect for pain relief, naloxone blocks the effect, and proglumide increases the effectiveness. But for the people who don't experience the placebo effect neither of them do anything.
If that's the case I don't see how that prevents anyone from testing my suspicion.
But it may well that a person that's susceptible to placebo pain relief might not be susceptible to placebo treatment for something else. However that would also be worth investigating.
I hear in some burn cases they can't use real pain killers, so they inject saline into them and tell them it's a powerful painkiller. And it works well for enough people. Another thing expensive placebos work better than cheap ones:
Genes do have a strong influence over intelligence. Just a few genetic differences can make a world of a difference. Chimpanzees are supposedly very similar to humans genetically, but they certainly have very different IQs.
There may indeed be karate genes, after all I doubt a hamster is going to win any world karate championships. But the karate related genes are many and have multiple purposes.
Seriously though, winning a 100m race just involves you running faster than the rest - far simpler process (not saying it's _easy_, just less complex). Winning a karate championship on the other hand requires you to actively adapt to and anticipate other people's actions which can change in response and anticipation to yours. So it is likely to involve a lot more genes.
You could be born blind (faulty genes for that) and still win a world class 100 metre race, but if you're blind you'd have to be amazingly good in other areas to still beat sighted world-class opponents.
So the Jews that didn't value learning and intelligence died out? And so now more of them are smarter? Sounds like selective breeding to me. No doubt nurture plays a significant role in development, but they're more of "watering and feeding the plant". Given a reasonable environment, the plant you eventually get depends a lot on its genes.
> Ethnic groups are a sociological classification and have little or no bearing on actual genetics.
But there are breeds of humans nonetheless. Though the differences are not as significant as they are for dogs, they are there.
So far there's just one breed of humans that does well in the 100m race. Only two non-west african breeds have done sub 10 seconds, and one of them just barely. Out of more than 1 billion chinese, they still can't field a sub 10 sec 100m sprinter. African pygmies aren't going to be running faster than the west-african breeds either.
The fastest chihuahua isn't going be faster than the fastest greyhound anytime soon. A fat slob couch potato greyhound may be beaten by the fastest chihuahua, but there certainly is a difference in the breeds.
And the East African breeds seem better suited for long distance running than the white caucasian breeds especially in warm humid conditions:
I'm curious how the white caucasians will do in freezing air temperatures or even subzero. After all it seems insufficient cooling can be the first limiter for physical performance, see:
> In the air, you can have a strict protocol and lack any weird topology that makes ground-based driving so arbitrary
> that would take off in your driveway and land at the local shopping center or at work
And the buildings and stuff around shopping centers or common workplaces don't create any obstructions?
Flying in the air may be easy for computers, the trouble is "air travel" usually involves getting close to surfaces at some point.
The problem with people controlling flying cars is unlike flamingoes, people don't know how to flock, don't know how to take off and land as a flock (just go watch a huge group of flamingoes circle to land - all without crashing into each other - you think the average person is going to be able to do that as well?). And I doubt this will change.
The problem with computers controlling flying cars is that current computer systems can't even safely drive cars. Controlling "flying cars" as popularly imagined (take off from driveway, land near workplace) would be harder than controlling road cars on typical roads. If you think VTOL is easy, then why were there so many problems in the lunar lander competition? There are no trees, street lamps, advertising billboards/blimps and other flying vehicles on the moon to avoid.
If you are taking off from and landing on special purpose airstrips/airports/airpads it becomes and easier task but then they are just planes not "flying cars". You can already get planes, and that means you'd still need some other vehicle to get you to your workplace or shopping mall.
Will be a bit scary at the start since people tend to avoid new barbers - few want a crap haircut even if it's cheap. So may have to do some marketing and promo.
> When will we admit that there are genetic differences? For example, most East Asians suffer from lactose intolerance. Europeans do not.
Despite more than 1 billion Chinese people out there, so far none have done very well in the 100m sprinting event. Don't see any Usain Bolts coming from those lines any time soon... There are just a few million Jews, but they have contributed disproportionately in so many fields - science and arts. And great influence in other fields such as finance.
I believe there are breeds of humans just like there are breeds of dogs. The differences aren't as marked/significant as they are for dogs, but they are certainly there.
Yeah that rule is crazy. It's crazy to prevent people from carrying water or their cosmetics and similar stuff onboard.
They stop someone from bringing in a bottle of moisturizer, but when someone goes through the scanner and it beeps, they just look at his keys, coins etc and let him through.
Given their procedures I think it's easy to sneak onboard a dangerous amount of [fill in the blanks yourself terrorist, I'm not gonna help you that much;)].
It's all to make people feel safe, not to actually make people safe.
That said, people feeling that plane travel is unsafe (even if untrue) could actually cause a lot of damage to the airline industry.
