I'll bet dollars to doughnuts that I can disable a $500 drone with little less than a portable radio, my laptop and a couple of bucks worth of radioshack equipment.
Would it be feasible for a drone to communicate via Iridium using an antenna that is shielded against signals coming from below?
Cooking isn't just about putting water in things, you know...
Also, rice does indeed appear to be a desiccant, just not as strong a desiccant as purpose-made things like silica gel. It's fairly common to put a few grains of dry rice in a salt shaker to prevent the salt sticking together from moisture.
It is weird but nowadays is easy to realize that google ceased "not being evil" sometime back there in 2005~2006.
Google's IPO was in 2004, and what was to happen was obvious then. Publicly traded companies can never be more than amoral, and anything that looks like "doing the right thing" is a kind of marketing.
It's a nice idea, but there are some laws applied to businesses which are basically never enforced. For example, I doubt anybody has been prosecuted for selling radium-based cure-alls in the past 20 years.
The USA has compiled a list of the countries it considers most repressive, and attempted to forbid the citizens of those countries from using encrypted communications... I don't think the governments on that list mind.
It sounds more like Obama is tired of seeing blatant attempts to imply his (or Michelle's) endorsement of practically everything (which is a clearly deceptive practice). I doubt very much that an elementary schooler will get a visit from the secret service if they print one of those photos for a diorama.
"It sounds more like [The Government] is tired of seeing blatant attempts to [do something stupid] (which is [obviously wrong]). I doubt very much that [people not doing wrong things] will get a visit from the secret service if they [quite innocently violate this excessively far-ranging policy or law]."
Please, everybody, stop posting things that fit this pattern. They have never, ever, been correct before.
nobody uses most of the functions on their fancy non-virtual calculators because it's a real PITA to figure them out.
For a certain value of nobody - looks like you just aren't the user such devices target. Try studying physics or maths.:-)
I have Casio fx-991ES. It's not a graphing calculator, but it does most things that one would expect from a scientific calculator (trig, powers, logs, etc. etc.), as well as definite differentiation and integration, vector and matrix maths and equation solving. I have genuinely used (not just played with) every button and the majority of the feature (decimal to octal conversion springs to mind as a feature I don't actually need).
Now, each to his own, but I have always found it easier to find and press the button with a square root symbol on it than to consult a spreadsheet's help system to find out what they've called their square root function (sqrt()? root()? squarert()?).
I'm not arguing against spreadsheets; they most certainly have their place, and I use them, but that place is things like doing stats on medium-small data sets, (or doing any maths repetitively on a medium-small set of numbers) keeping track of money (of course), and the like.
Between problems you solve with spreadsheets and ones that require the use of proper computer algebra systems, there is a large space which is still best served by calculator-style interfaces. For example, suppose you want do something simple like use the quadratic formula on something with too many fractions to be done mentally (at least by me). It's going to look very nasty in a spreadsheet, but can be done in less time than it take Maple to start up (yeah, extreme example). I'd use my calculator even if my computer was already booted, unless I already had a CAS running.
My calculator also has the advantages that it will actually lay it out pn-screen (roughly) as if on paper, which makes mistakes more obvious, than they would be in the mess of brackets a spreadsheet formula would have (multiple brackets with no syntax-highlighting - hell), and will give me the answers as exact fractions or surds if possible.
How fast can an FPGA be reconfigured? I suspect that they would not lend themselves to task switching as readily as CPUs do, and the potential of FPGAs to accelerate day-to-day tasks would be somewhat reduced if only one process could use it at a time.
No. The US is, I believe, the world's largest market for selling software. To sell into it, you have to follow US law, including patent law. So for anyone who wants access to that market (i.e. the majority of software developers), they have to follow US law wherever they are; therefore why bother relocating outside the US?
Even if the EU is a smaller market than the US,* it would still potentially be worthwhile to develop non-US software if it was going to be significantly cheaper (due to patent licensing and massive legal costs) to make, especially for smaller developers. It could also end up being cheaper to obtain bespoke software, which won't care about weird American laws if the company commissioning it doesn't have an American branch.
* I wouldn't know how to go about finding such stats, but the EU has a greater population and GDP.
I don't even see enough parts to make it work at all. You'd need one relay to provide ignition power, then a second to hit the starter
You missed the bit where he's using a cheap remote-start thing (presumably works like a remote-unlock, and over similar range) and modifying it to work with a mobile phone.
Nedlohs has it right: Slashdot editors apparently haven't heard of Autogas.
All I can add is that LPG is not actually the same as the stuff called "petrol" in English and "gasoline" in American. It's a lighter fraction that would be gaseous at RTP but is kept as a liquid in a pressurised tank.
Speed of reading is not a bottleneck in understanding code anyway, since I am sure it is pretty uncommon to be able to understand code while reading it as fast as you would read a novel.
And there are numerous disadvantages: lack of alignment, smaller punctuation making syntax errors less visible (" '" vs "' " for example), etc., etc.
Where the average annual income for a factory worker is a paltry US$1,150.00 annually!
An annual income of US$1,150.00 annually? How much is that monthly?
the keyboards, servers and mice that comprise these servers!
I see you have never built a server.
Sadly, your post will probably still be moderated higher that it would've been if it'd come second because you actually read it before clicking submit.
They are not actually the same. Ctrl-alt-backspace tells X to quit, which it will do if it's actually well enough to listen. Alt-SysRq-K is a key combo for the kernel, and tells it to kill everything running on the current virtual console (originally so that you could make sure you were typing your password into the getty instead of into a program another user had left running to phish login details).
This has the advantage that it will always kill X, even if X has hung (and will always give you your display back unless the graphics driver has left the adaptor in a weird state), and can also kill whatever (graphical) program had made the system unresponsive, even if it's malfunctioned badly enough to continue eating resources after losing it's connection to the X server.
Having the search engine available, and notifying people that results have been removed, is probably better than simply not making it available, leaving people using engines which don't tell them when stuff has been censored. They've also done much better than others such as Yahoo!, who keep data in China and actively help the authorities track down dissidents.

Element names are used to honour people and places for all sorts of reasons, and Copernicus clearly deserves it.
Röntgen's contributions were not exactly nuclear physics either, and Alfred Nobel wasn't even a physicist (neither was Vasili Samarsky-Bykhovets).

A Linux distribution typically involves Linux.
As for the rest, I agree that it's a bit confusing, especially given the choice of license.
If the commercial features slo-mo burning mosquitos, I'm sold.
In fact, they could probably just charge for the vids.

You can already do that in 4.3...

PHP is cross-platform. Who the hell develops on Windows on purpose?

Or "anything more complicated than adding a few numbers, it's easier to open a calculator than to learn how any particular spreadsheet functions".
That's really just a fancy way of saying that you are familiar with a spreadsheet, and not with a calculator program.

LPG and cooking gas are both usually ways of saying propane/butane mix. Any ideas as to what they're trying to say here?

That's a very good idea, and it would be possible to prevent idiots from using IE anyway by having different proxy settings in each browser.
