*deep breath*
Didn't Slashdot already cover this story within the past few months? I know I have read about this in the recent months. Some dude with a remote control can make people swerve as they walk.
I feel like I have finally arrived as a/. reader, to recognize a dupe... I'm so proud!
Crystal Pepsi was pretty cool.. although to my taste buds, it tasted a little more like Diet than regular.. Maybe they had to resort different means of flavoring that wouldn't color the syrup? *shrug*
3) My understanding was the DVD is read switching layers every spin, but is recorded top layer, then back layer
I really don't know what I'm talking about here, but I *think* your understanding is incorrect.. Otherwise, why would some DVD players have the layer-switch bug (a brief pause in the video playback when switching between layers)? If what you say were the case, those players would not hesitate once, but every however-long-one-track-is (probably varies with encoding quality).
...in more ways than one, as someone may have already pointed this out but I don't have time to read 5 pages of comments to find out.
From TFA:
"Airbus says that the A380 has achieved redundancy by installing the extra cabin-pressure valves, which provide a safety cushion in case a valve fails."
Wait. What? How does that protect in the slightest if one or more valves fails in the WIDE-EFFING-OPEN position? That's the defendant's whole point, that the valves fail by opening when they're not supposed to. You can't exactly close the other ones more than fully closed to compensate.. Granted I know nothing about ingress vs egress rates, and whether one wide-open valve can be compensated with intake, but from the article, it sounds likely that such a failure would be a failure of all the valves at once, not just one.
All hail the power of the almighty _(insert monetary unit of choice)_. Clearly worth more than thousands of human lives.
You're an idiot (or at least your book is). (Pulling numbers out of my butt here) It's gotta be a good 90% of consumer internet usage is hugely asymmetric. That's why asymmetric consumer ISP services such as...oh, ALL of them (ADSL..Cable..Satellite..Even your 56kbps modem tops out at 33.6kbps upstream)...are so successful. "HTTP/1.0 GET/" doesn't need 24Mb/sec to get to the host (for all intents and purposes) faster than you can blink. Does the average consumer send the same number of bytes in e-mail that he receives? Does the average consumer serve web pages from home, or videocast, or perform other high-upstream-demanding activities? Even online gaming is (probably) asymmetric -- I'm no expert in the matter, but it seems to me that my computer needs to know information about everyone else in the game (in order to show them to me) but only needs to report information about me.
Case in point, if you're a Windows user, pull up your Network Connection properties. Look at the Packets Sent and Packets Received numbers. Which one is bigger?
And yes, I realize you may not be a typical consumer. I am not a typical consumer -- I host web pages, e-mail, and routinely tunnel Remote Desktop over ssh to my home connection. And I realize that I am fudging numbers and leaving out symmetric services (such as leased-line solutions like T1, although I don't consider most of those "consumer" services), but my point remains that it's not simply marketing hype as you suggest, and entirely useful in "real life."
Er.. Hasn't this been done? It's my understanding that this idea (multiple cameras aimed at a single point) is exactly how The Matrix (and later NFL, though more cheaply) achieved its pause-in-the-middle-and-rotate effects, among other things. I'm not sure if they took it as far as building a real-time model; it was probably all straight interpolation in post-processing...but the idea is more than a concept already.
This probably oughtn't be a top-level comment, but I didn't have the time to dig down to find a more appropriate place for it.
From an attack vector perspective, it seems pretty easy to defeat in a pretty simple way; all one really needs to do is mangle the hash in some predictable way. I wrote a Java class that inadvertently mangles (on average) half the bytes of an MD5 hash (swaps some bits around) because of some bonehead logic on my part converting unsigned bytes into hex strings. Since it mangles it the same way every time, it still functions perfectly, but its output is not a plain MD5 hash. I went through a series of hashes created by that class at the FA's website, and not one of them returned a hit.
Sure it's simplistic, it's security by obscurity, etc. etc. etc., but it's mostly effective against an attack based on precalculated hashes. An attacker would not only need to intercept the hash, but also the pattern for mangling it (entirely possible, but one more hurdle at least).
Not to mention that any of a number of other tricks, such as have been already mentioned (salting, hashing a concatenation of username/password, etc), would be equally effective.
I'll probably get modded down for Redundant or Boneheaded or Naive, but that's what's great about Slashdot. I can make my boneheaded opinions known with impugnity!
So anyway, yeah.. Should be a quick "yikes!" for anyone simply poking md5($pass) into a db, but otherwise, blah. Interesting way to chew up a huge amount of storage space, but not terribly exciting until they map all 2 ^ 128 possible hashes (over 3.402 x 10 ^ 38).
I think it's actually résumé anyway; that is, acute accents on both Es.
Modern English, however, is definitly a wacky language. Why don't any of these words rhyme? Bough, trough, through, though, tough. That's, in order, "bow" (as in genuflect, not as in ___ and arrow), "troff", "threw", "thoe" (rhymes with toe), "tuff". And that's not even to mention the name Colclough, which around here is usually pronounced "Coke-ly."
Exxxxxxactly. I have no insider information, but I have a very strong hunch that the crimes Microsoft is aiming to quell with this laughable donation is pirating Microsoft products.
The Durham Freeway (I think.. some major thoroughfare around here...and that's Durham, North Carolina, USA; not County Durham, UK) near the Research Triangle Park does have split signs, but only for the distances (i.e. Raleigh... 5mi... 8km); not for speeds.
The problem with the sticker idea is that does nothing for mile-markers. I don't know if Canada uses a similar idea, but we have small signs every mile (more frequently in some places,.5 mi, even.1 mi) on most, if not all, major thoroughfares denoting your position from an arbitrary zero point (often a state boundary). This is helpful for emergency crews to pinpoint locations of accidents, etc. All the mile markers would have to be pulled up and respaced; I doubt drivers would be as happy with "1.6km markers"....just as functional, yes, but lazy Americans (yes, I count myself among the lazy!) would dislike all the decimal places.
Yes, conversion is possible and might even be a change for the better, but would encounter such inertia as to be incredibly prohibitive.
This report cannot be copied in any form what so ever.

Well, yes, I guess it can be.

A very large current is useless if the voltage is too low to overcome the impedance of the circuit you want to use.
THAT is pure nonsense. Dude. Ohm's law. (Excluding non-Ohmic materials, as someone has suggested). E = I * R. I = E / R. PERIOD. There's a reason it's called Ohm's LAW. If "...the voltage is too low to overcome the impedance of the circuit..." then you don't GET a "very large current." You get a very small current.
Plenty of electric welders' outputs have potential differences of a mere twelve volts. This gives the electric welder a great safety measure - if I inadvertently connect myself across the welder's terminals, I don't evaporate in a puff of burning cytoplasm because of my body's internal resistance. However, when I touch the welder's brazing rod against the material being welded (presuming all surfaces are sufficiently prepared, clean of all high-impedance materials), the fractional resistance results in a very large current (still only a potential difference of 12V), dissipating enough power to melt metals together into a very strong bond.
I love when people hot-headedly defend statements that are patently wrong. Bottom line, man, high current is high current, and current comes from the ratio of potential difference to resistance (also excluding magnetic inductance which was previously mentioned).
As far as I can tell, they're not selling anything.
Um, what?
Shortly after its inception, I purchased a "low-res" (something like 1024x768) image from TerraServer for something like six or eight bucks. Microsoft isn't, wasn't, and never has been in the habit of giving things away for free when the market doesn't demand it (as is the case for web browsers...and yet in the face of that, Opera continues to flourish). You could look at the pretty (albeit old) satellite pictures all you wanted, but if you wanted to keep a picture (for me, it was an image of the lot where my house was built), then you had to shell out the clams.
It's only logical. Our right to peaceably assemble is in the process of being eviscerated, which means that future efforts on the part of the citizenry to protest the increasingly hateful policies of this government will become more and more confrontational, and which in turn sees the government resorting to ever more punitive policies in response.
Yeah, as I'm sure has already been pointed out (again, too many comments to read them all), a "riot" is not a "peaceable assembly" and should be controlled by whatever means necessary.
