top Daylight Saving Time ...
I just wish they'd pick one time -- Daylight Saving or Standard, I don't care which -- and keep that year round
That is equivalent to abolishing Daylight Saving Time. Day Saving Time only works (for rather feeble values of "works") if the time changes. If it stays the same, schedules will simply readjust over time to follow the sun. A good example of this is Easter Island: the official time is two hours ahead of solar time. Therefore businesses open and close two hours "later" than they do on the mainland.
top NASA Admits It Gave Jet Fuel Discounts To Google Execs' Company
Right. It looks like NASA was simply selling fuel based on their own cost. They may have long term contracts and/or just not buy fuel all that often so it is possible for that on any given day, their costs are askew with average retail rates. Now I guess they will hire someone to monitor retail fuel prices every day to make sure they don't undercharge startups resident at Moffett Field when they occasionally buy fuel. Maybe this will make a little bit more money for Federal Government. Maybe the extra revenue will be lost in the extra overhead.
top Facebook Shuts Down @Facebook Email System
Definitely. Facebook email is an awkward and crippled parody of email. It is something to put up with for communicating with people who don't use use real email or who you don't trust with your real email address. But, seriously, why would anybody want to use Facebook email for communication that doesn't involve Facebook?

The school year and the material that can be covered in it is finite. If you add hefty new requirements, something else will have to be dropped. Maybe they can trim out all the "controversial" science.

top Computer Geeks As Loners? Data Says Otherwise
US Engineers are older though so it makes sense that more would be married. It is a commonly quoted statistic with the IEEE but perhaps not well known elsewhere that their membership is getting older 1 year per year. The same is not true in China and India.
top How Online Clues Located North Korea's Missile-Launcher Factories
Note that apparently the KN-08 is a liquid-fueled ICBM, which means it is completely useless for defensive purposes (you don't store liquid fueled missiles fueled-up, you fuel them just before launch - which would take too long to allow them to be used to react to an attack), and only really useful for a first strike.
Not necessarily. Titan II used liquid fuel and could be kept fully fueled in the silo indefinitely.
Atlas could be fueled in 15 minutes. Late variants reduced this further but loading the kerosene in times of high tension, which could remain in the rocket for long periods, and only waiting to the last minute to load the liquid oxygen. These versions were also kept in silos so they were only vulnerable during the time needed to load the oxidizer.
top Ask Slashdot: Why Are We Still Writing Text-Based Code?
In practice, I believe that the present text-based programming paradigm artificially restricts programming to a much simpler logical structure compared to those commonly accepted and used by EEs. For example, I used to say "structured programming" is essentially restricting your flow chart to what can be drawn in two dimensions with no crossing lines. That's not strictly true, but it is close. Since the late 1970s, I've remarked that software is the only engineering discipline that still depends on prose designs.
Funny that you should say that. For the last 20 years, the trend in Electrical Engineering is away from graphical entry and toward text based design languages. Hardly anyone designs logic by drawing gates anymore. We use languages like Verilog and VHDL, which look a whole lot like software languages. Even the analog designers make use of Verilog-A or even just Spice, all text based. When it comes down to building a circuit board or analog circuitry on a chip, there is still a manual "compile" step of drawing diagrams and polygons but that is only because the result is ultimately a three dimensional object (well, more lke 2.5D) and it is the only way to be sure you get what you intended. It is not because creating designs graphically is considered convenient.
top Building Deception Into Encryption Software
Bad form, I know, to respond to your own posting. But it occurs to me that data specific compression could accomplish the goal. Credit card numbers have structure. If you create a mapping between only valid card numbers and the minimum number of bits then encrypt that then it doesn't matter how the data is decrypted. It always produces valid looking credit card numbers. The catch, though, is that the bit mapping needs to be exact. If the total possible credit card numbers is not a power of 2 then there will always be decryption failures that produces detectably invalid results.
top Building Deception Into Encryption Software
If the software is detecting that the key is bad then all the attacker has to do is use software that doesn't do this. This assumes that the attacker has direct access to the file. If not, then well known throttling techniques apply and the new wrinkle doesn't buy much.
Making bogus data come out without requiring specific software for decryption seems like a very hard problem. Every data type will need, not just unique software but unique encryption algorithms that are both secure and not trivial extensions to known algorithms.
top IBM's PC Junior Turns 30, Too
I never ran into software compatibility problems with my 1000 (for non-game software), but it sucked that Tandy essentially put an EGA adapter in it, but then modified it enough that EGA software wouldn't work with it..
It was not modified EGA at all. It had exactly the same video as the PCJr and output one bit per RGB + one bit luminance just like and compatible with CGA.
EGA was very different in memory layout and EGA monitors used two bits per component.
top Tesla Wins One Over Chinese Trademark Troll
Tesla was not competent enough to register the trademark in all markets it was going to do business, and someone else did. Rather than working out some medication where Tesla paid for the lack of foresight, it was simply taken away. I don't think that the ruling was wrong, obviously China does not value the free market the way the US does, but there should have a happy middle between millions of dollars and something reasonable to pay.
The only reasonable value to pay to a troll is zero. Actually, no. The correct amount is that the troll pays the victim for their trouble and legal fees. A reasonable compromise is zero. The company in question was 100% troll. They were not doing business under that name. They had no intention of doing business under the Tesla name. This is true regardless of whether Tesla was "competent" enough to defensively register its name in all markets before it had product to sell just in case a troll an idea how to make some easy, unearned money.

top Water Plume Detected At Dwarf Planet Ceres
But as we understand it, water vapor
plumes likely mean bodies of water; and so far, in nearly all cases, bodies of water do equal life.
Not in this case. According to TFA:
Astronomers think that as Ceres reaches the closest part in its orbit to the sun, the more intense sunlight causes its icy surface to sublimate (i.e. turn straight from ice to vapor without transitioning through a liquid phase) at a rate of around 6 kilograms (13 pounds) per second.
So, no liquid bodies. Just solids and gas.
Liquid water requires a substantial atmosphere, which Ceres lacks. At low pressure, ice converts directly to vapor and visa versa.

top 95% of ATMs Worldwide Are Still Using Windows XP
Is a bad choice anyway. Not just a Microsoft bash, but aside from all the security issues, windows is XP is a desktop platform, not a OS to be putting on dedicated devices ( even the so-called embedded version really isn't any more appropriate for this, don't let the marketing folks fool you )
An ATM should be running off a custom embedded OS targeted for this purpose, not a commodity OS.
Who is going to write, maintain, and keep secure this custom OS?
The trouble with custom embedded OS's is that, in spite of the best intentions to limit their scope, they almost always need more features than can be written from scratch by a small team and be obviously secure. So they port code from more commodity OS's. Due to limited resources, the code in the embedded OS tends to fall behind. The porting effort can introduce bugs too that are non-obvious to the guy doing the port because he doesn't fully understand what he is porting.

top CES 2014: 3-D Scanners are a Logical Next Step After 3-D Printers
The same thing is going to happen to physical objects as 3D printers improve and eventually maybe we arrive at Star Trek-type replicators. If the facsimile of a precious original artifact is indistinguishable from the real thing, does it really matter which is the original?
That depends on what sort of object it is. If it is merely a decoration then perhaps it doesn't matter. An approximation indistinguishable by the senses may be good enough. On the other hand, if it is an artifact worthy of detailed study then it may have more to tell us then we already know. Microscopic details may be important. The isotope ratios in the material may even be significant. We can never be sure that a copy is truly indistinguishable where it counts.
top Ask Slashdot: How Many (Electronics) Gates Is That Software Algorithm?
The manufacturer is probably asking how many gates you need to implement the algorithm exactly as it is coded, with exactly as much parallel or sequential logic as it already has, and that will have a fairly specific answer.
While that number could be determined, it would not be very useful. Hardware implementation, especially when targeting FPGA's, get most of their performance advantage by exploiting more parallelism than is achievable by running on a processor.
No, the manufacturer isn't make any assumptions about how the algorithm is translated. The deal in gates. Gates are the most direct measure of how much the hardware will cost to manufacture.
Without a direct number for gates you will to come about in in a more indirect fashion. How much memory does the algorithm use? What data structures are used how big are they? (*all* data structures. An integer is a data structure for this purpose) What operations (adds, subtracts, etc) are needed and how many are required to go from input to result? With those you can usually come up with a ball park guess of how many gates will be required. There are always optimizations and non-obvious operations that get overlooked but it is a good start.
top I think wearable computing will take off...
When I think of wearable, I think of devices imbedded in clothing. Smart watches and smart glasses are just devices held in a slightly different manner.
For truly wearable computing, the devices needs to be survive in all the same conditions that clothing does and be comfortable enough to wear without a thought. Those are pretty hard problems. Not many devices today would still be functional after going through the washer and the dryer and are much too bulky and/or heavy to wear all the time.
top Federal Judge Rules Chicago's Ban On Licensed Gun Dealers Unconstitutional
It seems that firearm ownership rights are the only Constitutional issue that this Supreme Court intends on correctly dealing with. At least it's a start - our other rights emanate from the 2nd Amendment.
Bah. I see no evidence that this Supreme Court is correctly dealing with the Second Amendment. I only see a slight tilt toward those who want to mostly ignore the second amendment but still keep their toys and away from those who want to get rid of the toys too.
Overthrowing an oppressive government (what the second amendment is about) requires modern military hardware. In this age, that means tanks, RPGs and military aircraft. When the Supreme Court rules that private ownership of these must be allowed then I will believe that it is handling the Second Amendment "correctly".
Less you think I am nut case who actually wants my neighbors to be toting rocket propelled grenades: I don't. But that is what the second amendment means. As long as we have a section of constitution that it is considered OK to grossly misinterpret, all of our rights are in danger.
