  1. Re:Important distinctions on Rackspace Shuts Down Quran-Burning Church's Sites · · Score: 1

    (3) "Clear and present danger" is a recognized exception to free speech. Don't yell fire in a crowded theatre, etc. The *predictable* result of Dove's action is a sharply increased risk of retaliatory attacks killing US soldiers.

    I'm not so sure this is a fair comparison. When "Fire!" is yelled, or when a fire alarm is set off, people should respond, to not only keep themselves safe, but to also help other people be safe (by clearing the way for their exit and not getting stuck in a burning building and forcing a firefighter to come in after you). When a Koran is burned, there is no practical duty to respond.

    Well, maybe, in the Muslim culture and religion, there is. Actually, when someone yells "Fire!", you want the theatre to evacuate in a calm and orderly manner, and not as a panicking mob. Maybe when a Koran is burned, the Muslim community wants to present a visible protest, but not a violent one.

    So, yelling "Fire!" has the real risk of inciting panic, and burning a Koran has the real risk of inciting violence. But then again, burning a Koran is a way of stating an opinion (though not a good way of stating an opinion, and not a very good opinion, either), while yelling "Fire!" states no opinion at all. So I dunno, maybe it is a fair comparison, maybe not. Haven't decided yet.

  2. SIMD on AMD Details Upcoming Bulldozer Architecture · · Score: 1

    I worked with 128 bit SIMD (Single Instruction, Multiple Data) on an Intel x86 processor for my undergrad capstone, specifically SSE4.1. SIMD mainly allows vector operations. As one example, instead of adding 42 to a single 32 bit number in RAM, you can add 42 to four 32 bit numbers in RAM, if they're all next to each other, and do it in almost the same amount of time. Good for graphics and, well, vector operations. Kind of the CPU's answer to the GPU's specialties.

    My capstone dealt with finding out if an ignorant person who otherwise knows assembler can use SIMD in general purpose cases to speed up his program. The answer is 'probably not', as SIMD tends to mess up branch prediction, pipelining, and out of order execution, and it can take significant overhead to make SIMD work for you. Best to stick with what it was specifically built for if you're going to be using SIMD.

    Looks like the original Facebook "people" account they made was removed (probably by North Korea when they realized it didn't make sense to have a "people" account), and replaced with a "page" thing. I noticed the original account's username was uriminzokkiri, and the new one is uriminzokkiriLike, so maybe North Korea changed accounts primarily because they want the Like button? Lots of guessing here.

  4. Privacy on Smart Trash Carts Tell If You Haven't Been Recycling · · Score: 1

    , a trash supervisor will sort through the trash for recyclables.

    I was under the impression that sifting through someone's trash, at least before it gets combined with other people's trash, is illegal in most states. Like dumpster diving behind a competitor's corporate office looking for useful information. Also, my university had painted signs on their dumpsters saying something along the lines that the contents were the property of the university and looking through it would be trespassing, and I had heard they were backed up by Maine law.

  7. Behavioural Manipulation on Zombie Ants and Killer Fungus · · Score: 1

    This article reminds me of a good comic from The Oatmeal describing a flatworm that engages in similar behavioural manipulation: Why Captain Higgins is my favorite parasitic flatworm - The Oatmeal

    If both a fungus and a flatworm can make an ant climb onto the right leaf, I wonder if there's some easy way to trigger an algorithm in the ant's brain that homes them to the right spot? Oh, and if I recall correctly, there's a bee or wasp that can sting an ant's head, injecting its venom into the correct nerve area, to allow the bee to lead the ant to a good eating spot, like leading a horse by its reigns.

  8. I See What Happened Here on US Students Struggle With Understanding of the 'Equal' Sign · · Score: 1

    BTW, the example equation (function?) of 4+3+2=( )+2 is weird. It would be more proper to write it as 4+3+2=X+2. Anyway, I think I can see why someone would make the example mistake. It's a confusion of the order of operations. If someone thinks + and = are on the same level (like + and - is) and does it left to right, then an ignorant person would see the equation as [4+3+2=( )]+2. Therefor, they replace ( ) [or x] with 9, and then tack on the +2 and solve/compute the new 9+2 equation.

    By the way, on a related note, is there any proper way to add on operations to an equation that you're solving or simplifying live? For example, when trying to figure out the proper placements for the items on an image, you may be working with a bunch of dimensions and considerations. As you muddle through it on paper, you write 73-27=46. Then, you realize you need to subtract some more, so you continue writing and get 73-27=46|-24.75=21.25. Then you realize you need half that, and so you write some more and finally get 73-27=46|-24.75=21.25|/2=10.625. Of course, if you were to present this to someone, you would write it as (73-27-24.75)/2=10.625, but a train of thought (or at least my train of thought) doesn't always think that far ahead during computations. So, I use the bar | notation above, or sometimes use new lines, but is there any "proper" way to do it?

  11. Not Much of a Problem for Techies on The Recovery Disc Rip-Off · · Score: 1

    All you really need to do is torrent an OEM version of the OS disk you need. Since you're not downloading a cracked version and you'll be using the Windows key sticker (certificate of authenticity) on the bottom or side of the machine, the legality of the download is gray, and the morality of it is fine.

    However, there were a couple problems the computer repair place I worked at came across. When Vista first came out, lots of people ordered laptops that came with Vista, but requested that XP be put on it. The distributors did this, but never gave the customer an XP COA, or a recovery CD. So, we had to tell customers we could put on Vista using the COA the machine had, or contact the manufacturer and ask for an XP disk that might cost money and would take a while to ship. Fortunately, the distributors did but on an XP recovery partition you could use if the HDD wasn't failing, though of course it came laden with crapware and such.

    There was another problem, too. Microsoft now purposefully makes it so the text and keys on their COAs wipe away after a couple years. They say they do it for security reasons, but it's annoying as hell.

  13. My First Language on TI Calculator DRM Defeated · · Score: 1

    My first programming language was TI-BASIC on the TI-83 Plus graphing calculator. Made some nifty things with that. Then, my second language was assembly for the Z80 processor on that calculator. Self-taught from random how-to's found online. It was that that made me realize I liked programming, and was the primary reason why I became CS major at college.

    AFAIK, TI made no attempt to stop assembly program support for the TI-83 Plus. In fact, if I recall, one of the ways to get an assembly program onto a calculator was by using a TI produced software application on your computer. If TI had attempted and succeeded to stop assembly support for that calculator, I may not be the programmer I am today.

    TI, for the sake of our future, please let us hack our calculators.

    YouTube - Clay Shirky: How cognitive surplus will change the world

    Bug finders are both producers and consumers of the entire actions and consequences in the process. Finding and reporting security bugs is a civic action (as opposed to a communal one). Having the bargain for this action be based on economics instead of social rewards and punishments may have an adverse affect. So, it may be possible that people who get paid for reporting the bugs may feel that they have performed their entire duty that may have been present, and not go above and beyond in helping the community. Or, they may even keep the bug to themselves, believing the bug is worth more money than what's being offered, and forgetting entirely about the community. I think it's worth considering, at least.

    I don't have any write-protect drives on me right now, but I think these may have worked in the past: ComboFix, Dr.Web CureIt!, and... oh, that's it. In your search, try looking for 'portable' versions of your favorite virus scanners; that's what they usually call the kind that can run off flash drives, and some may work on write-protect ones. BTW, if you're worried about licensing, running from a locked flash drive may not clear you automatically. When you run the program, it kind of "installs" to RAM, and if it needs to perform a reboot, it may write some stuff to hard drive, not to mention the log files that may be written to HDD.
