  1. Re:Assumptions? on The Other Side of Diversity In Tech · · Score: 1

    The summary says that increasing diversity will be good for innovation and technology, with no stated reason as to why. So I'll ask: why will increasing diversity be good for technology and innovation?

    Well take it to a technical extreme. Which is better? An all-Linux or an all-Windows office? Or an office that uses a mix of Linux, Windows and other OSes?

    And by better, I don't mean "easier to support" - it's easier to support the same environment, but which one leads to more interesting ideas and innovation?

    Heck, we've gotten rid of the IE6 monoculture of the web - would you say things are better now that we've got diversity of browsers (even though it's only 3 engines - WebKit, Trident and Gecko) and people are doing interesting things, or were things better when everyone was just coding IE6?

    And in general, like begets like - if you have 5 white dudes, they generally will be very similar in thinking - purely because each one got hired for compatibility with the others. In a more mixed environment, there's always going to be conflicts so it's very difficult to hire someone who won't cause issues sometime (unless they're completely passive).

    Or, put another way, diversity of working environments - would you want to work in a place where the walls were beige, every cube was identical to every other cube (and personalization is limited by fiat), or one where employees are allowed a splash of color, personal items, etc?

    Well, some things really are more convenient with a "smart" home. Sure you can always work around it, but sometimes the peace of mind is better.

    E.g., verifying and setting the alarm - people still forget to set their alarms when they leave, and if you're going on vacation, checking to make sure while you're waiting for the flight can spare a lot of annoyed kids and other things. Plus, if you know a friend is coming over to take care of the place, you don't have to give them a code (many alarms have multi-user codes), you can always just disable it remotely then re-set it.

    Or front door cameras - perhaps you're expecting something and the delivery guy is early. You can get systems that let you talk to the guy, even open the garage door so you can have them drop it off in there. Saves having to make it to the depot because the guy's a few minutes earlier than you, or having packages left out in the open ready for stealing since it'll be put in the garage (which you can shut remotely as well).

    There's always the other ones - being able to come to a pre=cooled or pre-warmed house, for example.

    No, public access was never turned off. You need the "public" (C/A for Coarse Acquisition) signal even to get the P (precision?) military signal.

    A military receiver first acquires the C/A signal, like a civilian receiver. it needs this in order to get all the timing locked up so it can then acquire the P signal to get the necessary correction information.

    During the first Gulf War, military GPS units were hard to get, so they turned off selective availability so soldiers could use the civilian GPS units they brought with them. Then once the war was over, they turned selective availability back on to make the results imprecise.

    All GPS units need the public (C/A) signal first before they can do anything.

I wouldn't be surprised to see that, as well as cores that are dedicated to specific tasks, but general tasks can be put on those cores if need be. For example, a core for AES, cores that are optimized for floating point operations, but can do integer math, GPUs, a specialty core that is intended to be just for security sensitive processes (perhaps even running a Harvard architecture so that heap smashing is not possible), maybe even FPGAs.

    Most ARM SoCs already have that, actually.

    AES cores are called "security accelerators" and practically all modern ARM SoCs have them for security - either with full disk encryption or just offloading the crypto tasks. Floating point - ARM has the Vector Floating Point (VFP) unit for some time, though most people use NEON, the SIMD version of same.

    Security sensitive processes? ARM has that too - TrustZone, and many SoCs even have a low-end ARM7 or ARM11 that stays in secure mode and handles everything involved in bringing the system up. It's the first processor that starts up, which then initializes peripherals, RAM, then boots the big powerful cores that you associate with the SoC. The big powerful cores handle the user level stuff, while system level stuff like power control is often passed to that system controller core.

    That's why credit cards are generally safer - you call them and everything's restored. You might be out a credit card for a few days as they reissue a new one to you, but no thief can hold your account hostage.

    And no, your credit history is not impacted if you're hit with fraudulent charges.

    Debit cards are governed by the fairness of your bank - many are offering the same protections as credit, but there's no legal requirement for them to do so. You have legal rights when you use a credit card, which include being able to report fraudulent usage, stolen cards (to which you're only liable for $50) and a host of other things.

    Admittedly I have no clue. Sports games were never my thing as a long time PC gamer, but whenever I see friends playing them, it's usually on a console on the couch. I imagine it would feel really weird to play it on PC. It's quite feasible that target audience for FIFA games on PC is tiny.

    Two things were the primary cause of the decline in PC DRM usage. First was the rise of the console as primary seller of games. Second was the rise of a PC only genre that was piracy free - MMOs.

    Consoles meant people were spending money on games, so they became the primary development target - plus low piracy meant plenty of money. It's why PC ports started to suffer because they weren't bringing in the money (piracy, among other reasons). And with Steam, well, its DRM is "good enough" that once the consoles paid off the development costs, all Steam had to do was pay off the porting costs to PC and then it was pure profit. Of course, they could do a crappy port and refine it as money came in.

    Indie games never had DRM so they didn't bother - they had other issues to deal with (obscurity for one) so piracy didn't really represent anything more than "marketing budget".

    This is not your old 70's LORAN system. Thanks to advances in DSP processing, eLORAN gives your position with precision comparable to GPS (10m or so). It also have data channel that's used to broadcast DGPS corrections, so it complements GPS nicely.
    Because of low frequency, signal penetrates buildings and ground (however with greatly reduced range). This may be one of the solutions for a car navigation in tunels. Even if it produces less precise position, it's always better than no position at all.

    Great contrast between UK and USA, where LORAN transmitters were demolished in the past years. When so many things dependd on GPS signals, we really need some backup system for precise timing and positioning. Not thinking about backup only means we will learn about it the hard way - and it will not be pretty.

    Depends if they only plan to deploy them along coastlines or everywhere.

    LORAN worked only because it had a collection of towers spread out in a line, and the preferred navigation route (most accurate) for LORAN involved being perpendicular to the line. For shipping routes that was great since they generally were well defined paths.

    But if you're randomly tuning in a LORAN station, the accuracy (especially "reversed") was questionable at best.

    The US decommissioned them because they were expensive to maintain, few people were using them (compared to GPS) and touchy to use.

    Plus, GPS is so integral to US life that introducing an error signal back or turning it off would literally disrupt the US economy. Not just satnav, but satellite tracking and monitoring of equipment, timing (GPS is used to distribute time and synchronize clocks (required for cellphones)), navigation (RNP - Required Navigation Performance, is a new method airplanes use to approach airports that lets them fly closer in and lowered minimums, and relies heavily on GPS, which saves time (less time cooped in the cabin) and fuel, and makes the airports more efficient).
