Scientists Capture the Sound Made By a Single Atom

CSMoran Re:10^5 slower? (100 comments)

I hate when people say that something is "3 times slower," as if that means anything. I know what they are trying to say, but the correct way to express it is "one-third the speed," or "one-third as fast."

Just imagine "slowness", measured in s/m, is the reciprocal of "speed". Three times slower means its slowness is three times bigger compared to the reference, thus it's 1/3 of its speed. Worth making a fuss of?

Autonomous Car Ethics: If a Crash Is Unavoidable, What Does It Hit?

CSMoran Re:Statistics betrays you too... (800 comments)

Worse yet: if you're alone in your car, your car might actually choose to kill you.

Now that would promote carpooling.

Dropbox and Box Leaked Shared Private Files Through Google

CSMoran Re:If it is linked, it is public... (92 comments)

It seems like the "vulnerability" that the article is talking about only happens when a recipient of the dropbox file link copies that link address into a google search query. If the user just clicks the link like a normal person, there is no problem.

No, that's only half the problem. The other half is that if your shared document contains a link to, say, and someone clicks this link straight from within the document, can look at the referrer field and get the "secret" link to your document.

WikiLeaks Cables Foreshadow Russian Instigation of Ukrainian Military Action

CSMoran Re:Well ... what do you expect (479 comments)

Precedence is a bitch, the US set the precedent and now they are winging about what is happening in Crimea !!

Precedence only matters in law, in places that use common law. In other legal systems, precedence doesn't matter at all.

It matters diplomatically and in propaganda.

Scientists Demonstrate Virus That Spreads Across Wi-Fi Access Points

Being DOS the only solution was to hit the hard reset button.

Meh, you just map the int 00 vector onto int 05 and you're ready to go. Press "Print Screen" anytime to divide by zero and terminate current process.

Winamp Shutting Down On December 20

CSMoran Re:Will you people please stop whining? (400 comments)

But you don't need a network exploit to worry. Secunia PSI routinely pointed out buffer overflows in how .mid files were handled in Winamp, prompting for an update. Now, I don't play .mid files, but if someone discovers an exploit like that in, say, how Winamp handles m4a or ogg files, with no dev to fix the security hole, how can you be sure your existing installation is not used to pwn your machine the next time you play a media file from teh internetz? Winamp hasn't changed much over the last few years, but at least they were patching security holes.

Not All USB Power Is Created Equal

CSMoran Re:won't help for Samsung note 2 (240 comments)

Voltage loss over such a cable is very real. At 0.14 mm^2 (AWG 26) you get 0.14 mOhm/m. For a 2m cable, 2 wires you end up with 0.56 Ohm. At 1.5 A that's a voltage drop of 0.84V.

A factor of 1000 snuck out on you here. You went from milliohms to ohms in a second.

GNU Make 4.0 Released

CSMoran Re:Me gusta! (179 comments)

Make has flags to enable and disable printing of output. If you want to debug your shit, just enable the output printing.

"Just enable" works when the 'make' you execute is the only one. In a maze of scripts and Makefiles and scripts generating Makefiles and scripts generating scripts that call make, euphemistically called "a custom buildsystem", hunting down the right 'make' to change into 'make -d' can take a while.

Ask Slashdot: How Best To Synchronize Projects Between Shared Drive and PCs?

CSMoran Re:stop trying, use git instead (238 comments)

Seconded. I use a 65GB git repo across four machines (two of them virtual) to sync my entire work history on a daily basis. Occasional 200MB files in there, but mostly smaller stuff (source, binaries, PDFs, word documents, datafiles). Never had a problem so far. Admittedly, no branching, just keeping a few hundred thousand files in sync across four machines so that I don't have to worry where my files are when I go somewhere with my laptop only.

Intel Announces New Enterprise Xeons, More Powerful Xeon Phi Cards

CSMoran Re:Programmers will be happy. (57 comments)

Yes, "well-known algorithms" is my use case -- massive LAPACK generalized diagonalizations that take forever on a single CPU, almost forever when threaded with openMP-capable BLAS to, say 8 cores, and do not scale at all to distributed-memory clusters (ScaLAPACK with MPI) because the comms becomes a bottleneck.

Thus I'm hoping for a solution where the vendor themselves wrangles those intrinsics in their BLAS or LAPACK implementation in MKL with me oblivious to all that mess. Assuming the computation time scales O(N^3) and the memory transfer over the bus scales O(N^2), with the prefactors in my favour, I should be able to squeeze out a significant performance boost.

Intel Announces New Enterprise Xeons, More Powerful Xeon Phi Cards

CSMoran Re:Programmers will be happy. (57 comments)

Does Intel's MKL support the Phis out of the box? It would be very convenient if, instead of having to re-write code for them, we could just use phi-capable BLAS and LAPACK.

Play Tetris To Fix Your Lazy Eye

CSMoran Re:Any Oculus Rift developers in the house? (88 comments)

The eye doesn't see, the brain does. The eye simply collects light and other signals (like the aforementioned focus thing) and transmits them to the brain, where the image is actually formed -- the image landing on the retina, for instance, is upside down and backwards. But you see things right side up and not backwards; the brain does that.

I agree with the gist of your argument; however, I think you've got the specifics wrong. Fun fact: human retina is actually considered part of the brain.
