    Please do not link to any site that autoplays a video. Chrome handles html5 natively. It is not easy to block it in chrome. That alone is going drive users away from Chrome to Firefox+NoScript. It is just a matter of time before advertisers and sleazy websites add autoplaying videos. It is back to X10 popup and blinking text of geocities.
    Thanks for the warning, you will see the drastic reduction in hits for such links from Chrome. You will create a policy of not linking to any site that has auto play video. Also why do you include it directly in read? Can't you just put up a link and say click to play?

    Just can't win, can you? I mean, back when it was some proprietary flash player everyone complained because Linux doesn't have Flash, other than Chromium.

    Now we got to a nice standardized format (HTML5) and people still complain?

    And in reality, the <video> tag has an "autoplay" attribute - if it's present the video autoplays. if not, it doesn't.

    (And if you're handy, in the DOM there's a piece of javascript that writes the video tag and sets the autoplay option based on a setting).

    If you want, write to Mozilla, Apple, Microsoft and Google to have them ignore the autoplay attribute if present so videos don't autoplay at all no matter what the webmaster's intent. It's the advantage of HTML video - the user is in charge and their browser is free to ignore or obey the webmaster's intention.

    Just like most web browsers ignore "text-decoration: blink " (blink tag has been deprecated in a CSS world. Though most browsers actually don't obey the CSS either).

    However, the answer is likely that it was an easy way to unlock phones sold in the N. American market. Every time Apple releases a new phone, a bunch are bought up on the west coast by people who jailbreak them, unlock them, and then sell them in Hong Kong, Taiwan, and mainland China. This likely accounts for both the large number of jailbroken devices and for the decline, as a larger and larger number of legit devices are sold directly into the Chinese market.

    Don't confuse North America with the US.

    iPhones sold by Apple in Canada without a contract come SIM unlocked by default. If I wanted to wait, I could've had an unlocked iPhone 6 (or 6+) on launch day.

    And other places often sell unlocked iPhones.

    Plus, on launch day, there are NO jailbreaks for new devices. So unlocking them is basically impossible via the jailbreak route.

    And the incidence of jailbreaking in Asia is going down, as it turns out by jailbreaking, you're getting your phone infected with all sorts of spyware. There already are a bunch of iOS spyware that infects jailbroken devices only because they require circumventing the iOS security system in order to function. They can't infect a non-jailbroken phone.

    So the only reason for jailbreaking in Asia is to engage in what they consider their basic right - to pirate. I mean, the latest installs of the jailbreaking tools for the past few iOS revisions install some Chinese pirated app store.

    Of course, elsewhere on the Internet, the other way to do pirated app installs is to use a re-signer service that uses the enterprise certificate to sign cracked apps so they install on unjailbroken phone. It probably explains why the iOS section of most sites is gathering dust, while the Android section is healthy and growing with dozens of new pirated apps posted daily.

    So they're basically negating the one major aspect of a drone, the ability to fly significant areas autonomously by tethering it to someone on the ground. Sounds like bureaucratic red tape to me, if you can't kill a thing make it useless to do it by wrapping it in so many "common sense" measures as to make it useless. I can understand some things, requiring insurance, constant tracking, keeping records, but maintaning line of sight either shows a complete lack of understanding of what a drone is or a blatant attempt to kill a (possibly) nascent industry.

    The problem is, and has been, that drones need to integrate into the air system we have today. Low level flights are generally allowed because aircraft don't usually fly that low (hence the 400 foot rule), but once you go above that, you can find yourself in the middle of air traffic - maybe not so much an airliner, but bug smashers and helicopters. And if you're going to be in that, you need to participate in full VFR rules at a minimum (including see and avoid). And if you can't see your drone, well...

    In fact, that's been the primary problem the FAA has been wrestling with - how to integrate drones into the national air traffic system. Everyone wants the same rules applied - if your drone is going to occupy the same airspace, it will have to obey the same rules, including necessarily avionics (transponders, controlled airspace and ATC, etc).

    The lowlevel rules are an attempt to let a fledgling industry not require everyone who flies a drone be a fully licensed pilot.

    (The NTSB has ruled that even RC planes are "aircraft" and ARE subject to the FARs. The FAA's advisory is just that - advisory on how to partake in the hobby in ways that are unlikely to call the FAA's attention). So the FAA wants to treat small drones as RC style aircraft with the same RC style limitations.

    It's already happened that idiots have tried to abuse it (hence why the NTSB has ruled RC aircraft are aircraft) - some idiot with a drone was bobbing and weaving it and causing a nuisance to the public flying it through pedestrian tunnels and dive bombing them, etc.

    The problem is, drones are so easy to fly, most users are idiots, and the FAA has to basically balance the demands of fully licensed airspace users against those of hobbyists and small commercial operations.

    Large drones are still subject to full pilot and aircraft/airspace regulations. (There also have been large RC aircraft that end up having to qualify under experimental aircraft rules).

Inner packaging will often be missing since who wants to spend $20 for the 2,000 extra pieces of packaging? $10 worth of bubble wrap ought to be sufficient.

(And I'm being generous, I've seen ones using 30ga or thinner "rated" at 13-15A - if you remember how thin the wires were in a ribbon PATA cable, think using that for a power bar).

    Then there's the group of people who take rejected parts and wire them up and hope no one notices - like perhaps a chip failed thermal testing - it still works, but only if you keep it under 40C or something. Those rejects usually get discarded, but smart ones will recycle them and use them elsewhere, maybe even a third shift product. Imagine powering up your server only to have it die under load because the part (which was rejected) failed and you have a copycat item.

    Fancy trackers may track additional features since clients return how much they upload and download, so the tracker may use that to track your ratio (usually by user-specific tracker URLs).

    But there's nothing the tracker has that says anything more than "hash - user IP". It doesn't know what the files are, or anything else.

    I'm starting to believe that Linux has finally hit a limit--it excels in the business (server, routers, robots). Forget the direct-to-consumer space--it's not gonna happen, and Ubuntu phone sort of solidifies it w/all the hype that came with it. Hi, FreeRunner 2....

    Linux does fine in direct to consumer space, actually.

    You just have to abandon the notion of "a Linux box" as acting how Linux does on the server and other things you know and love.

    Replace the upper level guts with something more reasonable and you know, Linux is popular. A stunningly large number of devices run Linux in consumer devices, and Android powers a lot of phones. The thing in common is that the Linux core is hidden behind a pile of custom code that hides its nature because it has to.

    Things like SystemD, NetworkManager, PulseAudio and other big blob programs are attempts to get "regular" Linux to behave more like how consumers expect their devices to behave. Which are incredibly complex behavior that can't just be tied together with a bunch of shell scripts.

    Just think how basic operations are done on Android. It's obvious Linux can do them, since Android can do it, but damn is it hard to get desktop Linux to behave like Android.

  24. Re:retcon much? on The Man Who Invented the Science Fiction Paperback · · Score: 1

    What lead to the popularization of science fiction, arguably, was the technological innovation in print. That is, printing paperbacks was cheap enough so that even if very few books sold, it was still possible to at least break even. The advent of the paper back is like the advent of direct to video movie. Lower risk, more titles, profits are driven by the few that sell well, the rest are pulped.

    Actually, what made printing cheap was the mass market paperback - not paperbacks (which existed for a long time). A mass market paperback was a way to print cheap copies and distribute them beyond the traditional bookstore - those books you saw on the shelf at the supermarket are mass market. Basically by using fixed dimensions, cheap paper, cheap glue bindings and very fast printing, you can make a readable book really cheap. Combine them into an assortment of books (all the same size) and you can ship boxes to distribution centers and then to stores who put the books up on the registers pretty much randomly.

    This gave you wide exposure (a print run of 1000 was cheap, and probably went to 10% of the stores that sold mass market paperbacks - 1 each among the assortment), and the cheapness of it all made the assortment cost effective. It didn't matter that not all stores had the same books - they just got some and if it sold, good, if not, it got returned and lumped into another assortment somewhere else a month later.

    So the mass market stores got a constantly cycling collection of cheap books they could sell. If you were a reader, you went to the higher quality paperback editions that were printed much better and lasted longer, but were more expensive. Also you went there because mass market books were a hit and miss random collection - if you wanted a specific book, you were better off going to the bookstore.

    These days, the term is basically meaningless other than to refer to a specific form factor of book as stores switched from carrying pulp as a impulse sale to a common stock item. But back in the pre-internet days, mass market was a good way to get exposure.

    What I want to know is: Since this is a 'trend' a lot of car manufacturers are headed to, in another couple years where am I going to be able to buy a car that doesn't have all this crap in it? CAN bus is ok to a degree, but I don't want (or need) a bluetooth/wi-fi enabled integrated digital everything car. Give me the old 'needle' speedometer, flipping number manual odometer, etc - I don't want a 'digital display' where everything breaks at once if it dies, I don't need or want my stereo integrating into the drive train, and it doesn't need to tell me the temperature, weather, gps, and all that stuff - I know when it's hot or cold out, sunny or rainy/snowy, and I can read a map. I want *less* technology, not more.

    Import brands from lesser known countries. Or higher end vehicles. Or learn to love classic cars.

    The thing is, your needle speedometer hasn't been wired up to the wheels in 20 years or so now - they're all electronic with a servo giving your the needle position. That's basically true for everything you see on the dash - it's all electronically driven and controlled and the only things you feed it are a CAN bus network plug and power. Sure some gauges flick when you turn the key, but just because they don't doesn't mean it isn't electronic.

    So the needle and flippy odometer are basically purely electro-mechanical devices in most cars, and of the whole cluster, only the speedometer is the required instrument. And there are probably enough purists out there where the needle instrument would remain an option. They all get the information the same way so it's really a matter of swapping the panels around during manufacture.

    As for all that "electronic crap"? They've gone this way because electronics have proven themselves to be far more robust, durable, cheaper and way more featureful than their old mechanical counterparts. It's why throttles are electronic despite supposedly being more complex - a throttle cable fails surprisingly often versus your pot and servo (while the latter gives you cruise control as a free option - it's just software now). Brakes remain hydraulic with mechanical backup (though many are electric rather than vacuum assist). Hell, even your transmission is basically all electronic - automatic transmissions used to be almost all mechanical but that lead to the control box being very finicky where 1/16" of an inch can trigger a recall. It's why modern automatic transmissions are so efficient - knowing how the engine is loaded, the speed, throttle position and many other sensors, the transmissions can figure out what gear to use.

    And yes, going electronic makes life a lot simpler - the mess of a wire harness is far simplified, it's cheaper to manufacture, and way more reliable. It's also why previously high-end features reserved for luxury cars can be hand in your $15,000 econobox. In the end it's all software, and software is remarkably cheap.

    Of course, it's unlikely remote update would become a standard low end feature anytime soon - I mean, you have to handle cases where the vehicle may not be set up to connect to an owner's wifi network, 3G isn't available everywhere (and who's gonna pay for it?), etc.

    That said, remote access does have its uses - perhaps monitoring your car from inside the house. This will be more standard in range-limited vehicles like electric cars, so you can see the status of your car inside on your phone (state of charge, charging or not, etc) and even have it run the AC or heater while still on house power so the car is cool or warm when you get in.

    Anyhow, you want electronic crap free cars? We call them classics. And even those aren't all electronics-free, as people have learned that electronic fuel ignitions make life much nicer (twist 'n' go - no longer worry about vapor lock, cold weather, etc.), and yes, you can get 'em with automatic transmissions too, and creature comforts like AC.

    Of course, if you do go true all mechanical, be prepared to spend a few days every month working on it. It's why there are a lot of shade tree mechanics - things fail constantly.
