  1. Re:Tools available? on NVIDIA Tegra K1: First Mobile Chip With Hardware-Accelerated OpenCL · · Score: 1

    Google should do something (and soon) because Apple's metal API supports GPU compute workloads. Sure you can do GPGPU using OpenGL ES but that is more limited in scope than a full CL implementation...

    First, I consider this a very cool development, that a major GPU manufacturer actually caught on that people use their hardware for more than just gaming. That said...

    Be careful what you wish for. Offloading work from a CPU to a power-hungry GPU makes tons of sense in a desktop, or even server (for certain workloads) environment - ie, "plugged in". Doing the same on a mobile device, not so much. On IOS, people have consistently reported drastically reduced runtimes per battery charge when running "hardware accelerated" apps. And don't take that as a rant against Apple - I have no doubt we'll see the exact same problem when Android finally standardizes similar support.

    If the systems were affordable without the special arrangements and tax breaks, this article wouldn't exist in the first place because the panels would be popping up all over Florida.

    "Affordable" means different things to different people.

    As the GP meant it, "affordable" means having a positive ROI with a reasonably short payback period (well under 5 years, currently, and that assumes going totally off-grid; a grid-tie installation can pay for itself in literally half that). As you mean it, someone living month to month on their minimum wage paycheck can't afford to sink $20k up-front into a PV installation.

    As a cruel irony, Florida's law doesn't stop those who can front $20k from putting in their own solar array. Instead, it stops the people who most need it from using the "lease to own" model made popular by those companies already mentioned - Kinda the same idea as a cell phone subsidy with a two year contract, except on a bigger scale.

  3. The ROI calculators show a first year 7% ROI (of course, this will increase as electricity prices increase).

    Although not DIY tends to basically double the price, you realistically have a 2-3 year payboack, or an ROI of 33-50%.

    I have a 5YO toy 500W DIY system, currently, and it has already more than paid for itself, without bothering to get a second meter to take advantage of generation in excess of consumption (yeah, you want to know why the utilities suddenly and "inexplicably" wanted to move to smartmeters? Unlike the old analog meters, they won't simply spin backward if you make more than you use, so FUCK YOU, consumer-with-solar).

    The Brookings institute clearly analyzed this from the POV of a monopolistic unitility company, because for end-users, a home solar array practically counts as a no-brainer with current prices, assuming you can afford to sink a few grand into it up-front.

    Seconding Ubiquiti gear. I use these (not your specific models, but I love their nanostations) and they simply don't die. Literally months of uptime without a glitch, and even after a power outage, they pick right back up doing their job without human intervention.

    And range? I've used a pair of bridged nanostations, without any external antenna (they come with a built-in 120 degree sector), to cross slightly over a mile (with line of sight) pushing full speed without even breaking a sweat.

    For about 50% more than a cheap consumer grade router (and the same price or less than the supposedly "high end" consumer crap), these suckers count as a no-brainer if you want something that just works.

    Warning - These do not make a good "my first WAP". Getting them configured correctly (even legally, since they'll readily let you blow the doors off ERP and go outside local frequency restrictions) the first time can take even someone familiar with what all the features mean quite a few trials-and-error, and I'd consider that one of their weakest points. But they do it all, and they do it well... WAP? Router? Bridge? WDS node? Check.

    Note that I mean this somewhat in the abstract, in the sense that I refuse to work for someone who expects me to work more than 40 a week regulary. My current employer actually treats me pretty well, and as a result, yes, if I automate task X, I'll spend my newly-found time doing the rest of my work somewhat better (I wouldn't specifically say "picking up new tasks", because we all know that what we can do in 40 hours doesn't mean we should to produce the optimal result).

    Yes, Kudos to NASA for going to the trouble of setting up an actual "null" hypothesis test - Except, how about they try the experiment as documented before they go tweaking the conditions in unknown ways? Yes, they thought they built a zero-thrust version of the setup... Except, that presumes that Shawyer actually has the correct theory behind his understanding of the effect.

    Canadians can't block .ca, of course. They probably feel pretty much the same as I do about .il, .ru. and .cn, however. Canadians can't block the few diacriticals used in French (although in my experience, most Canadians would probably consider blocking Quebecois a feature, not a bug); I doubt they have a lot of use for Cyrillic, however. Similarly, a Russian mom-n'-pop probably doesn't get all that much email in Mandarin, even if they need to allow Cyrillic through.

If you allow students to only eat ham cubes, they'll never touch the broccoli. If you don't take five ranks in metallurgy, you can't open the "intelligent liquid metal" skill tree.

    Realistically, this would mean they'll just require a long chain of prerequisite "modules" for anything students actually want to take. Almost like structuring "modules" in to a "course" - Imagine that! Except, without the advantage of having a single professor aware of your progress through each step. You think the current semester-long course structure has a lot of duplication? Wait until each module needs to basically spend the first half making sure you actually know the half a dozen prerequisites, and still remember it enough to apply to the present topic.

    Bluntly, this won't affect most Americans for the same reason spam from .il, ru, or .cn doesn't matter - Because we simply don't get any legitimate email from those domains. It doesn't take your spam filter long to figure out "if the address contains character-X, 100% chance of spam"... And that assumes your mail server doesn't outright block those as a hardcoded rule (in a former life I had to babysit the Exchange server for a small business; if you came from anywhere not in one of the big-six TLDs, auto-junk).

    So by all means, spammers, please start using Cyrillic or vowels with diacritics in addresses - It will make you that much easier to filter.
