Luggage is only scanned when you check it, and when it gets onto the plane. Compare luggage tracking systems in airports to those used by UPS.
I guarantee that it is scanned many more times than that. The fact that it didn't get onto the plane and they don't know where it is doesn't have to do with how many times they scanned it, but more to do with mistakes made by the scanners or handlers. FedEx, UPS, etc. have been known to lose track of packages we sent from our office, though I'll give you, it probably happens less frequently than for airline baggage. I'm pretty sure that the main missing luggage problem is the luggage just not making it in time for the flight or connection, and the airlines deciding not to disrupt flight schedules and hold up 250 passengers and their next flight connections just for one person's luggage.
A lot of their layoffs and hour cutbacks are because of the digital photos and very sophisticated OCR. Of course storing them for more than a couple of weeks seems a waste of money, but maybe it's the cops or Homeland Security that pay for that?
I don't know about the keys, but the everglades' water levels are dropping because of a combination of less rainfall than in the past (climate change?) and agricultural and other diversions of the water that should be flowing into the everglades. It has nothing to do with sea levels.
Really, if there is a possibility of a leak that could asphyxiate someone, you should have a sensor that alarms on a drop in oxygen (or a rise in the other gas) and kicks in a ventilation system to can purge the gas and replace it with breathable air. You're probably violating mechanical codes, OSHA regulations, etc., if you don't have that.
What exactly was "stupid" about ActiveX aside from potential malicious code (either directly or via overflows) that was either enabled by default or presented to the user with a "just click yes so the website will work" style input box? Firefox "avoided" this by not implementing ActiveX but most or all of the functionality was recreated in Javascript, giving it basically the exact same level of "stupid"
ActiveX involves installing "3rd party" native code modules to get the desired functionality.
Javascript involves installing a "1st party" native code interpreter and running "3rd party" interpreted code in that to achieve the desired functionality.
It is somewhat easier, therefore, to use ActiveX to install an exploit vector.
I remember when MS launched Win95 people were very attached to how Win3.11 worked . . .
On the contrary, I remember that when I first used Win95, I felt that Windows was finally usable. (I always disliked DOS, but found DOS much preferable to Win3.11)
In what ways have the Service Packs changed XP such that average (or even "power") user would notice?
Well, SP-2 did render my printer unusable for 6 months until HP finally got around to issue and updated driver that worked. My fairly "average user" wife definitely noticed.
. . . if the average lifetime of a PC is five years, some 80% of the computers that were in use back in summer 2009 have been replaced by now.
. . . at an average lifespan of 5 years for a PC there should be nearly 1.7% replacement rate per month.
I believe your math is off. Your numbers describe the situation if all computers were replaced within 5 years, and then only if the replacement occurred at a constant rate.
Similarly for Moscow, half the first page results are for some insignificant location in Idaho.
I'll have you know my son worked for the university there one summer doing computer security research, you insensitive clod.
(More seriously, there's a not-insignificant US military presence in that city and school.)
You do know heart disease is a relatively simple, preventable illness right?
You do know that that some people that exercise often and eat properly still get heart disease? And that it is is associated with inflammation, right? And that low-level infection/inflammation is a contributing cause to clogged arteries? And that all sorts of things go wrong with the body and metabolism due to old age, regardless of the good diet you may follow, including stiffening of the blood vessels and valves, reduction in immune system response, slower repairs to injuries, poor hormone levels, etc.?
I think you misunderstand 'expression of an idea'. 'Studying code to apply the ideas' is not 'the expression covered by copyright'. Ideas are not covered by copyright. Functionality is not covered by copyright. Only the creative, original expression is covered. Using the black box approach is a way to avoid the argument about what is functional, what is expressive, what is copied, what is original, etc. Trial lawyers love to argue, but clients want corporate lawyers to help them avoid the trial.
The effect is strongly frequency dependant, and relies on tuned membranes
I was wondering about that. TFA left that out. If so, then it would more useful as a sort of filter, more than a device to reduce reverberation or increase transmission in general.
Can't think of a single use for this other than eves dropping where no electronics were allowed.
Actually, this might be useful for the design of sound attenuators. Letting the sound out of a space (say an HVAC duct) into another in order to absorb it with heavy weight mineral wool or the like could be a common application. TFA didn't go into any details, though, so I don't know if this could be any improvement over what is already done. (It sure sounds similar to how a lot of silencer walls are already constructed)
You understand incorrectly. HFT is doing exactly the same thing as day trading (well, not exactly, but close enough for this purpose), only faster and without sentiment . . .
No, the big difference (other than speed) between day trading and high frequency trading, is the HFT algorithms that make thousands of offers a second but retract most of them. A tax on retracted offers could help stabilize things greatly. A tax on competed transactions would not do much to affect HFT, other than to reduce the profit margin.
Hoffa was one of the original anti 1%ers so to say, but he did most of his work attempting to unionize America in the 70's which more or less lead to all the downsizing . . .
No, he did most of his work unionizing during the depression, when workers really needed it (when the companies were hiring their own thugs to beat up and shoot picketers). By the 60s Hoffa was just a union boss, and by the mid 70s he was disappeared.
Stainless steel would be prohibitively expensive, and might very well corrode, depending on the environment and the composition of the stainless steel. (stainless steel does not do well with chlorine, e.g.)
And rebar is already often epoxy coated.
The practical problem I read about this concrete discovery is that it cures very slowly. Until they figure out how to speed that up, it won't be too popular in construction.
That was to be the SSC, not the LHC, and the "politicians who smelled pork" was mainly Bush 1, who got it started in Texas in spite of the fact that if they built it at Fermilab a significant portion of the infrastructure would have already been in place.
"Everybody has a right to reasonably clean air, as part of the property inherent to all humans on earth." Is simply not true. I do not see any laws supporting this.
If you think the right to reasonably clean air would come from laws, you are mistaken.
Traditionally the approach would have been: "Dont think, cool down and re-heat the air constantly to dehumidify it sufficiently"
Actually, traditionally, the cooling and the reheat would each be cycled/modulated by the thermostat/humidistat, not run constantly
The mistake in this case was not accounting for changes in temperature and humidity, including the fact that the dewpoint temperautre of the air can change much more rapidly than the temperature of the solid objects in the room. It really was a boneheaded mistake, one that is hard to understand given the unusual nature of the HVAC for this facility; you would think that a lot of careful thought about the controls would have taken place during the design of something out-of-the ordinary.
I have designed around simlar potential problems on much more mundane designs before.

I must say, those are extraordinarily long Tuesdays you have there.

Each airport has its' own baggage handling systems, and those are often shared among different airlines.
No, the expectation of privacy for mail is a well established right. (but not for postcards or envelopes exposed to view)
It is a largely automated process, just about everything except the route of the letter carrier is handled by OCR, bar code, and machinery.

As someone with a Dad who is 92 years old, and in relatively good health, for his age, I will have to vehemently disagree with you.

Wisconsin also gets warmer than this place, though.
