    Even the "smart" remotes like my Harmony get around 6 months per 4 AAA batteries, while other remotes can go for at least a year, if not two or practically never (I've had some still with the original factory batteries - a wonder they didn't leak, and then the remote with new batteries works from the other side of the house bouncing the IR off the walls).

    In fact, it's usually why lots of jokes are written about remotes and batteries - they fail so infrequently that many people develop elaborate procedures to get them to continue working. And some people forget they take batteries altogether.

If you have the engine running and then walk out with the key, the dashboard display immediately displays a warning that the key is no longer in the vehicle.

    I presume the condition is checked when there is a status change in the car - e.g., the doors are opened or closed, but also checked at random intervals as well.

    No, Apple wasn't presented with a warrant to unlock that phone.

    Instead, the feds simply asked the court to force Apple to do it, using the All Writs Act. Basically the argument was since Apple could do it, and has, they should continue to do it. Apple however requires a legal document saying they should, in this case, a warrant (which means the judge was convinced there is significant merit in the case that it should be searched).

    No warrant was ever issued. In fact, the defendant pleaded guilty, which means it's even more unlikely the judge will issue a warrant. Instead the feds want to compel Apple to unlock the phone anyways (using All Writs) absent said warrant. Apple said no.

    The court case Apple won is basically saying that this was not a valid use of All Writs and the court refused to issue a court order.

    Better late than never. If they're better than their competition then they deserve some kudos. I doubt they'll make a great deal of money on recycling, the aluminum content will be a few cans worth... they will also recover some of the previous metals in the phone but there's precious little of those.

    This is probably about a combination of good marketing to a public which is increasingly concerned about environmental impact as well as a portion or corporate environmental responsibility.

    Actually, e-waste as it's traditionally recycled is still quite valuable - in fact, if you're a miner, mining e-waste is more profitable than trying to mine the ground - the concentration of precious metals is far higher and thus it's not only far easier to extract, it's more profitable.

    Using a robot means it's actually even more valuable - a lot of effort in the recycling industry is purification - an iPhone is made of glass, aluminum, steel, copper, gold, and other materials. The first stage of an e-waste recycler for small portable electronics is shredding - the pieces are then sorted in order to purify the materials - glass, metals (ferrous/non-ferrous) and plastics. The recyclers then buy those materials and pay based on purity.

    Using a robot to take apart iPhones means Apple can extract even more money because the purity is higher - all the cases can be separated which gives you high-purity aluminum, the cameras put together to be separated together into lenses, plastics and circuits, etc.

    The actual electronics themselves, uncontaminated with anything other than gold, copper, silicon, fiberglass and plastic (circuit board and components) can be ground up in a traditional method and then mined/smelted into high purity elements.

    So recycling an iPhone is profitable already. However, using Liam, recycling is likely to be way more profitable. It's just that disassembling is quite labor intensive. Apple is in a position where they can recycle iPhones over and over and over again rather than a thousand different phoens.

    Electronics recyclers do crude disassembly of major components - a desktop PC will be disassembled into case, circuits and other parts like drives, but stuff like laptops may not be disassembled because of complexity.

I don't want the larger phones because I can't easily work them one-handed but I'm not going to buy a smaller phone that's deliberately lacking in features.

    Or maybe it wasn't possible? Force Touch works because it measures the capacitance between the LCD and the glass. Given the iPhone SE reuses iPhone 5s parts (the case and display), I wouldn't be completely surprised if those parts lacked the necessary metal coatings to do the measurement. And given the cost, I'm guessing Apple would rather continue to use iPhone 5 parts across the iPhone 5 (warranty), iPhone 5s (warranty/refurbs) and iPhone SE line rather than have a special SKU just for the SE.

    Then again, it could also be that because of the smaller screen, force touch either doesn't work well (too hard to push at the corners, or too soft), or because of the glass geometry, results in cracking of the screen.

This is (even if it's not gossip) by far the worst form of "journalism" that exists, and people have to have no life at all and/or a huge inferiority complex to even care about it.

    Actually, the whole celebrity thing is changing - gone are the days from 30 years ago when everyone was awed by them. These days, there are few mega-celebrities - maybe a handful of actors that most people will recognize the names of.

    Why? Turns out Hollywood realized something - people don't give a damn about big names anymore! Big names don't sell movies and few people go to movies to see their favorite stars. Sure there are movies with big names on them, but they're generally not the big draw they once were.

    Hollywood is using more and more "no name" actors in big movies - because no-names cost less, no-names don't care as much about the movie (nor does Hollywood) - so it's no big deal if the movie crashes and burns, and if ti does well, well, the minor celebrity will probably blow all their credibility within a few years (who was that Transformers star again?).

    Plus, CGI'ing no-names is a lot easier and they're less likely to have likeness usage issues. This became a huge issue in Back to the Future part 2, where George McFly, played by Crispin Glover in the first movie, was replaced because Glover couldn't come to reasonable terms, so they used a lookalike and basically got into a huge lawsuit over "likeness" issues. Eventually SAG came up with rules saying you can't do that anymore. It's also why that scene was it - Glover was still in negotiations with the production company well into filming when the production company gave up, and rewrote all but the couple of minutes out of the movie.

    So, nonames are cheaper, movies generally do just as good with or without big names, and less issues overall.

The court is suitably not impressed and the jurors equally offended at the defense to stick it to Gawker.

    Disregarding a judge's order to take down the video, defiantly as well, is also not likely to go over with the courts. The appeals court may cut down the award, but it's likely not by much - the courts are not impressed by defendants who basically insult them, and appeals go both ways - the judge may have let the contempt charge pass at first, but it can be reinstated on appeal.

    The problem is, while the internet is global, most media distribution systems are not. Netflix is probably the largest distributor now being in 200-odd countries. And that is the point- the media companies want to deal with single companies - if you want to distribute content worldwide, they'd rather you be exclusive and everywhere than have to deal with 1000+ companies all dealing with little chunks of geography. Because negotiations then get tough - I mean, if you have a TV station paying you $X for your content with the expectation that the only other provider is Netflix, and they won't have it for a couple of months, they'll pay more. But if provider Y then comes in and beats Netflix to the punch, then negotiations get even harder because the TV station sees provider Y, sees they no longer have exclusivity, and probably only wants to pay $(0.3X), which means provider Y better make up the difference. But then in country Z, provider Y only had to pay 0.5X, so now the negotiations get hairy.

    Yes, media companies want to ensure people pay the max. One way is to sell exclusive deals. Otherwise if they get paid worldwide $100M for a TV episode with a few distributors, then when they do global distribution, they still want at least $100M, and that means giving up exclusivity in a lot of regions, so the former exclusive dealers may only be willing to pay $30M total, and now the worldwide distributors have to pay in total at least $70M. Otherwise they'll keep the old methods.

    And guess what? Only Netflix is of the size where that may be possible to offer global distribution.

    It all boils down to money. If Netflix alone can pay the $70M to make up for the loss of exclusivity contracts and the media companies make the same or more, then they will adjust to the new global distribution model.

    Knowing how many practical digits of Pi means even on Earth-sized values, we can use a lot less digits and pretty much call it an exact, practical constant whose error is so small you're going to encounter quantum effects.

    Yes, you can talk about significant figures and all that, but Pi can be treated as a constant - and like all constants, be of infinite precision and thus not affecting the significant figure count at all. Even though Pi is irrational, for practical purposes 39 digits will be all you need.

This is actually a very hard problem to solve and was a cause of a lot of Linux issues until the kernel fixed it for driver developers (by ensuring the exit code will only be called when all reference to other entry points were gone and there was no other code running).

    2) Aliased references. An object is created, and references to it are passed around to other bits of code that may make more references to it. Freeing the object means having to invalidate all those references, which may not be completely obvious. This could be say, a buffer being passed around the application that various bits are looking at various parts of it. Usually what happens is the buffer is processed and then forgotten, except someone say a neat way to implement a feature so what was stateless now has state. Free the buffer and there you go.

    It is tricky to resolve. The Linux kernel is a great way to learn all about it because you get multiple pointers to objects which is why they use the CONTAINER_OF style macros that mean you can embed a structure within another, and then using a pointer to the inner structure, get the entire object, reducing the need to alias.

The main reason for the pipeline was to make transportation crude oil easier from the Canadian tar sands to the US for refining and export. That was it. Now, it is a bit more environmentally friendly to use pipelines; however, that is contingent upon the utilization of the pipeline. With the dramatic decrease in oil prices, it is no longer economically viable to extract from the tar sands. As for other considerations, refining tar sands crude requires special facilities as not every refinery can do it. From the last estimates, 75% of the crude was designated to be sent overseas for refining. So realistically few American facilities would touch it.

    It was even worse.

    Keystone exists - it goes to Chicago where most of it is refined by American refineries.

    Keystone XL is an extension of Keystone, where most of the bitumen is to be shipped overseas as raw bitumen - Chicago would get less crude to refine.

    The real purpose of Keystone XL is to sell it on the international market, where the rates are higher, than the US market which pays a lot less.

There are approximately 86,400 seconds in a day here, but the mean solar day varies because Earth's rotation is not uniform. UT1 is the most common form of this, which is what time is measured at the prime meridian.

    UTC is time derived from the atomic clock. It closely approximates UT, but since Earth's rotation is erratic, to keep the UTC day closely aligned with the UT day, leap seconds are sometimes added to ensure the difference between the two times is under 0.9 seconds.

    TAI is the time as told by atomic clocks. Here, a day is exactly 86,400 seconds and there is no such thing as leap seconds - this is purely a monotonic clock that ticks away.

    The problem is, well, there are a lot of variables. UT is measured generally once a day and clocks set to its time. UTC is a close approximation and generally used as it's easier to obtain without having to have someone observe the Sun every day to calculate when noon is. TAI is just the atomic clock time.

    Leap seconds are introduced to keep UTC and UT relatively close to each other. TAI is allowed to drift, and eventually you'll have noon at midnight.

    Which you pick is up to your needs. Leap years were created so people in the Northern hemisphere wouldn't be celebrating summer in December as the calendar drifts away from Earth's position in its orbit..

    Then there's TAI, which is the true atomic time

    Plus, Apple is defending the morally reprehensible position of not letting device owners install whatever software they want whenever they want.

    IBM didn't allow you to install whatever OS you wanted on their mainframes. Technically you could but it would void the warranty and IBM would never help you again. (This was the same position as HP, Digital, just about every other mainframe and mini-computer maker).

    Apple allows you to install whatever you want for iOS nowadays - you just need a Mac to compile and build the software. It's a regular feature of XCode and iOS 9, and there are emulators and other stuff for iOS.

    Apple is enforcing it as open-source - the f.lux guys tried to do it with a binary and Apple asked them to stop abusing it. So there's something to give RMS a headache - a proprietary OS that allows/enforces open-source programs. Granted, you have to build them yourself as they don't allow binaries, but it's open source/free software so you can do that.

    As for IBM - most mainframes IBM provided are leased, not sold. IBM will provide you with a mainframe, and depending on what you leased, is what you got. The hardware itself was often overprovisioned - if you asked for 32GB of RAM, IBM would give you 128 or 256GB of RAM in the unit. (The extra could be used in case a module went bad, for example). Or if you asked for 4 processors, IBM would have 8 or 16 in what you actually got. They could be used as spares ready to take over, or if you need it, you call up IBM, pay the upgrade fee, and magically your mainframe has the updated capabilities instantly.

    All this is part of the lease. In fact, if you violate the lease by installing unauthorized OS software, IBM would immediately claim back their computer because it wasn't your computer to begin with - you paid IBM to lease the computer from them.
