  1. I imagine not on Microsoft Rolls Out Robot Security Guards · · Score: 1

    However the problem is that it can presumably notify security that you've done that. Given that they'll have full video of it, and know where the unit was, the chances of you getting caught are pretty high.

    These aren't the kind of thing that would work well on their own out in the middle of nowhere but on a campus like MS's with human backup I imagine they are pretty effective. Rolling security cameras basically.

  2. They do in Windows on Apple Disables Trim Support On 3rd Party SSDs In OS X · · Score: 2

    The generic MS drivers know how to see if the drive supports TRIM and send the commands if it does. That's the point of TRIM: It is an ATA standard command, so special software isn't needed.

    In fact, in Windows all you use is the generic drivers. I mean you may install drivers for your SATA controller, but not for your drive. My laptop has a Samsung 840 Pro in it, with Samsung's Magician installed. However the drivers in use are disk.sys, partmgr.sys (both Microsoft files) and iastorf.sys (Intel's file). No Samsung provided drivers. Magician can directly send commands to optimize the drive if needed if the OS can't, but the OS sends TRIM commands no problem.

  4. On enough with the whining on US DOE Sets Sights On 300 Petaflop Supercomputer · · Score: 1

    I hate this attitude that if you don't have the top spot, you are crap. It is so silly the attitude that the US somehow lost something by not having the first spot on the top 500 list.

    I mean for one thing, the Chinese computer is more specialized than the big US supercomputers. It gets its performance using Intel Xeon Phi GPGPU type processors. Nothing wrong with hat but they are vector processors hanging off the PCIe bus. They work a lot like graphics cards. There are problems that they are very fast at, linpack (which is what's used to test) being one, but others they are not as fast at. Many of the US supercomputers (like BlueGene/Q) use just standard CPUs, meaning their performance holds steady over more kinds of tasks.

    Then there's the fact that while the US might not have the #1 spot they have the #2, 3, 5, 7, 9, and 10 spots. In other words, half of the top 10 computers. That is more impressive than having one really big system. Ya it's nice to have a huge system and some simulations need really big systems to do, but there's something to be said for lots of different research groups having access to high power computers.

    Also there's the fact that linkpack isn't necessarily the best benchmark.

    I'm happy that the US is looking to invest more in HPC because money spent on research is always well spent in my opinion. However let's stop pretending like it is some major failure that the US doesn't have the #1 computer. Big deal.

  5. People tend to believe their first media on Alleged Satellite Photo Says Ukraine Shootdown of MH17 · · Score: 1

    I've seen the same kind of thing. I know a lady who's from Serbia. Very smart woman, and she's lived in the US for a couple decades, immigrated and become a citizen. However, when it comes to world news, she believes the Serbian media over all others. It's pretty bad too, it makes Fox News look credible (well almost) with the level of propaganda and shit. However, to her, that's the truth.

    It seems a somewhat common thing that whatever you start getting your news from first is what sticks with you as the "true" news if there's disagreement later.

  6. For some reason on Former Police Officer Indicted For Teaching How To Pass a Polygraph Test · · Score: 2

    Geeks have real issues with the concepts of knowledge and intent mattering in the law. They think something is either ok, or not ok, and if it is ok it is ok in all situations. Of course that's not how the law work. Intent in particular matters a hell of a lot. Something can be illegal or legal just based off of intent, or can be a different level of crime. Likewise if you know you are helping someone commit a crime, that can get you in trouble whereas doing the same thing unknowingly can be fine.

    It is complex, because it varies, there are crimes that don't require intent, or crimes where even doing it unknowingly will get you in trouble, but there are others that are not. It is complex with various shades of gray, which I guess is why geeks can't understand it. Many seem to be very binary thinkers and want absolutes in rules, which the law frequently doesn't have.

  7. Re:Quit buying games on day one on Assassin's Creed: Unity Launch Debacle Pulls Spotlight Onto Game Review Embargos · · Score: 1

    I think it's fine to buy them soon after release if you want them and can afford them (remember, to some people $60 for entertainment isn't a huge deal) so long as it has been properly reviewed and your research indicates it is a good game. There are plenty of games that launch strong, just as there are plenty that don't.

    But never buy it before you can research if it is good, and if you are likely to enjoy it.

  8. You are completely correct on Assassin's Creed: Unity Launch Debacle Pulls Spotlight Onto Game Review Embargos · · Score: 2

    And I am one of many people who harp on the "Never preorder games!!" thing. So why do people do it? Two reasons:

    One is they just get caught up in the hype. They are all excited and wanna have it as soon as possible. Silly, but human nature and it does happen time to time.

    The other is that companies try to bribe you. They offer bonuses that you only get if your preorder, or that you have to pay for later. So there may be some day one DLC, but you can have it "free" if you preorder.

    It is still, of course, and extremely bad idea to preorder and people should be talked out of it at every opportunity. Wait until it is out and reviewed, then decide if you want it.

  9. Also how much similarity triggers things on Duke: No Mercy For CS 201 Cheaters Who Don't Turn Selves In By Wednesday · · Score: 1

    There are only so many ways someone is likely to design some functions, particularly if the class demands particular formatting. So if having one function that is very similar or the same triggers it, then it is rather bullshit.

    I could see this too. Where I work professors are extremely lazy and grade via script. They don't read the programs students hand in because that would be "too much work", never mind that in the arts and humanities professors have to read papers all the time. Then they usually use some kind of automated cheat checker program. Well, said checkers aren't something that just makes sure files are bit identical. They allow for various fudge factor. That means they can match even on things that aren't actually copies of eachother.

  10. Re:Ok but that's electricity, not energy on Denmark Faces a Tricky Transition To 100 Percent Renewable Energy · · Score: 1

    I chose 25 degrees just since it is standard temperature. Either way if you don't believe me, look it up, a significant amount of energy use by humans is temperature related and cold areas use more than hot areas. Saul Griffith has done some great talks on the matter.

    I know that it is something of an article of faith that AC is the devil and hugely wasteful but that just is not the case. Heat pumps (that's what an AC is) are very efficient and getting better but they only work if the evaporator coil is warm enough that water doesn't freeze on it, precluding their use as heaters in any place that gets near zero. Because of their thermal efficiency compared to heaters and the fact that sorry, but cold places DO get colder than hot places get hot, even if you set 20 as the benchmark, people use less energy when they live in warmer climates.

  11. Ok but that's electricity, not energy on Denmark Faces a Tricky Transition To 100 Percent Renewable Energy · · Score: 2, Interesting

    Guess what? Cold places use MORE energy than warm ones. While people like to hate on ACs as some excess, they are actually quite efficient. Since they move heat, they can move more energy than they use. A good AC can easily move 3-5 watts of heat for each watt of energy it requires to operate. No such luck with heating systems, they at best get you 1 watt of heat for each watt they take.

    Then there's the issue of temperature delta. If we take 25 degrees (C) as a target room temperature, well then you can see why cold places have it even worse. The hottest inhabited places on Earth only tend to reach 40 degrees regularly and peak at 50 rarely. So a 15-25 degree delta from normal. The cold places? Hell, even a "mildly" cold place hits 0, and they generally drop a good bit below that. Denmark sees 15-30 degrees below zero. So a 40-55 degree delta. Of course the bigger the delta, the more leakage you have, the more energy you need, etc.

    If you intend that heating energy to be renewable, that means no oil, gas, etc furnaces. You can use electric, so long as the electricity is from a renewable source. I guess depending on your definition wood might be ok too. That's about it, unless you happen to live near some hotsprings and can get some geothermal heat.

    So re-run the energy calculation when all the district and local heating has to stop using anything non-renewable.

Probably once ever 5-10 years max. Well add in the cost of that now to the total cost. Also add in the energy required to create and dispose of said batteries to your calculation.

    Ends up not being a great option with current battery technology.

  13. We see that problem with graduate students on The Students Who Feel They Have the Right To Cheat · · Score: 1

    Being an engineering college we see many Indian and Chinese grad students. In both cases we numerous students who have real difficulty with any kind of synthesis and application of knowledge. They want to memorize a bunch of facts and formulas and crunch numbers to get the result. Solving real problems is something they have a lot of difficulty with. In particular there's not a good concept of problem solving. If they don't know the answer to something they believe the solution is to seek the person that does, not apply problem skills.

    It, unsurprisingly, comes from the elementary and undergraduate education they received. That is what learning is to them. It is a real issue since of course in real engineering, you don't get to work from a textbook.

  14. I's just a bullshit semantics game on There's No Such Thing As a General-Purpose Processor · · Score: 2

    Guy is trying to play silly distinction games. Really, everyone in tech understands what people mean when they say "general purpose processor." Yes, said unit may have some specialized circuits and such, but it is made to be good at dealing with all kinds of problems. Integer, FP, branching, linear, etc doesn't matter its design can handle them all reasonably well.

    That compares to something specialized like a GPU. For certain kinds of problems, specifically single precision vector math with fairly consistent branches, it does amazing. However for other things, not as much, though it is turning complete and capable of anything. Still a true processor and not an ASIC that can't be programmed, but not general purpose.

    Try to play semantic games with it is silly. Are there going to be cases where the line might be blurred? Sure, but who cares? That's how life is. Everything doesn't always fit in to neat little boxes. It is still a generally useful way of looking at things.

  15. 60fps doesn't need 2x the bandwidth on YouTube Opens Up 60fps To Everyone · · Score: 3, Informative

    Frames are similar to each other (this is a big way that H.264 gets compression) and the more FPS you have, the more similar the frames are since each is a smaller time slice away from the last one. So you may not need a whole lot more bandwidth.

    A good example is AVCHD, that's the H.264 camera format that is popular with consumer and pro cameras. The 2.0 spec supports 30fps and 60fps. At 30fps you store data at 24mbps, at 60fps you store it at 28mbps. Same visual quality, only 4mbps more to get the extra 30fps.

    Same idea scales down to lower bitrates. You do need more bits to maintain the same quality, but not a ton.

  16. It's also useless on Denuvo DRM Challenges Game Crackers · · Score: 4, Insightful

    The idea that bitchy DRM is what you need to make money is silly. The bitchier the DRM, the more it costs you in terms of implementation and support and, guess what, it turns out that a great many of those pirates just won't buy your game, they don't want it for anything more than free.

    You can see some good examples in the audio industry, which has some really bitchy DRM. Like take Steinberg Cubase and Cakewalk Sonar. These are two of the long time DAWs, both dating back to the DOS days. Both still make money, both are still in active development. Cubase uses super retarded DRM. A dongle that Steinberg bought and customized (syncrosoft, now called Elicenser) that is checked when you do anything. Seriously like opening menus has checks to the dongle. Sonar has no DRM effectively. You need a serial and an activation code, but the activation code is per serial, not per computer. It is just so you register your product with CW. The serial and code don't change and it doesn't phone home. Yet despite that weak DRM, Sonar continues to be developed and sold.

    Or in audio samples. The big name in virtual instruments is Native Instruments, their program Kontakt being the king of sampling. They have some fairly weaksauce DRM on their products. A challenge/response kind of thing that is cracked and pirated versions abound. Despite that, they make lots of money and are the unquestioned top of the sampling game. Then you look at EastWest who uses their own custom software with an iLok dongle because of evil pirates. They are too small for anyone to care about cracking. So no piracy, but they are tiny, a fraction of NI's size and profits.

    Really all bitchy DRM does is increase the cost on the developer. You end up spending more programmer time implementing it, more QA time making sure it works, and more support time helping people when it doesn't. There's no good evidence showing it increases sales. Remember that decreasing piracy is not the same as increasing sales. You can drop piracy to zero and yet discover you get little to no extra sales because the people who were pirating were only doing so because it was free, and have no interest in paying for it.

    When by "Strong AI" you mean "a computer with human like intelligence" that may not be something that can be done. We don't even know.

It may be no matter how powerful we make computers, no matter how clever their programming, no matter how much they "think" they are never a Strong AI. We just don't know at this point.

    So it is really premature at this point to be doing any kind of doomsaying, or other prognostication, about Strong AI. We don't know if such a thing will ever exist, much less what form it will take if it does. Like even if it can exist we have no idea if it would have emotions as we do. Perhaps those turn out to be biochemical in origin, and thus a Strong AI doesn't have the. So it might completely lack ambition, desire, anger, or anything that would lead it to try anything against humans. It might be completely self aware, rational, and perfectly ok with doing whatever it is told to do and serving humans because it simply has no desire for anything else.

    All of this is unknown, so maybe let's chill until we start to see if AI is possible, and if so what it is going to look like, before we get all doomsdayer on it.

    Want to know a big reason people have been getting Macs, that Apple doesn't like to admit? You can run Windows on them now. The Intel switch made it viable to run Windows on them, natively if you wanted, and good virtualization tech means it runs fast in OS-X. That lets people get their shiny status symbol, but still use the programs they need.

    We've seen that at work (an Engineering college). Prior to the Intel conversion, there were almost no Mac users. The thing is engineering software just isn't written for the Mac. There is actually some stuff now, but even so the vast majority is Windows or Linux. Back in the PPC days, there was almost nothing. So we had only really two stubborn faculty that used Macs, one because he did no research and just played around, and one because he wrote his own code and was stubborn. However that was it, you just couldn't do your work on them.

    Now? All kinds of faculty and students have Macs. PCs are still dominant, but we see a lot more Macs. However every one has Windows on it. Some it is all they have. Seriously, we have two guys who buy Macs, but have us install Windows on it, they don't use MacOS they just want the shiny toy. A number have bootcamp, and many have VMWare. Regardless, I've yet to see one, faculty, staff, or student, that didn't put Windows on it to be able to do the work they need to.

    I have 150mbps cable at home, and get what I pay for. Games from GOG and Steam download at 18-19MB/sec. It is fun, I can download a new game in minutes... however outside that I notice little difference from the 30mbps connection I stepped up from. Streaming worked just as well before, web surfing was just as fast, etc. The extra speed matters little to none in day to day operations.

    Same thing at work. I'm on a campus and we have some pretty hardcore bandwidth, as campuses often do, so much it is hard to test as the testing site usually is the limit. Downloading large stuff it is nice, though really not that much less time than at home. I don't really mind the difference between a 2-5 minute wait and a 15-20 minute wait for a program. Surfing, streaming, etc all are 100% the same, no difference at all, speed seems to be limited by waiting for all the DHTML crap on a site to render, not the data to download.

    While geeks get all over excited about bigger better more when it comes to bandwidth, for normal use what matters is just to have "enough" and "enough" turns out to be not all that much. It'll grow with time, of course, higher rez streaming, larger programs, etc will demand more bandwidth but still this idea that there is the difference between uber fast Internet and just regular fast Internet is silly.
