SpaceX To Attempt Falcon 9 Landing On Autonomous Spaceport Drone Ship

DMUTPeregrine Re:fuel weight (81 comments)

They're only lifting extra mass on the first stage, not the payload. So it doesn't have to move the extra mass as much.

Canadian Supreme Court Rules In Favor of Warrantless Cellphone Searches

DMUTPeregrine Re:Password protect your phone (105 comments)

For rooted phones, the Cryptfs Password app (Or any terminal emulator app) can be used to change the device encryption password without changing the unlock password. The encryption password is only needed on bootup, so be sure you have a way to quickly shut the phone down (lockscreen widget, customized power button long-press, etc).

Ability To Consume Alcohol May Have Shaped Human Evolution

DMUTPeregrine Re:Yet this doesn't explain (89 comments)

That's just due to the dilemma set up in our brains every time we try to cook: Do we cook the potato, or turn it into vodka and drink it? Do I make this wheat into bread, or beer? Add this barley to soup, or make whiskey?

LHC's 'Heart' Starts Pumping Protons Before Restart

DMUTPeregrine Re:Hydrogen atoms (50 comments)

Ionizing hydrogen DOES break apart the molecules. The molecules are held together by their electrons, removing those breaks the bond.

Study: Space Rock Impacts Not Random

DMUTPeregrine Re:"Random" (78 comments)

Heisenberg's uncertainty principle is just an application of the Fourier uncertainty principle to the quantum position and momentum wavefunctions. Since those are a Fourier pair, the Fourier uncertainty principle applies. So it's not a matter of which interpretation you pick, it's about whether QM is correct. If the behavior of quanta is not wholly determined by their wavefunctions then QM is wrong, and Heisenberg's uncertainty principle might be violated, since the true functions for position and momentum may not be Fourier pairs. This is widely considered to be extremely unlikely. Also, if spacetime is quantized (there's a minimum possible distance and a minimum possible time, and all times/distances are integer multiples of these minima) then the wavefunctions wouldn't be continuous, so the uncertainty principles might not be applicable. Loop Quantum Gravity is one theory that posits this.

The Effect of Programming Language On Software Quality

DMUTPeregrine Re:so, static == more defects? (217 comments)

Nope, though it's confusingly worded.

C, C++, JS, etc, have more instances where someone committed a fix for a bug (as opposed to new code).
Clojure, Haskell, etc, required fewer bugfix commits.

Denuvo DRM Challenges Game Crackers

DMUTPeregrine Re:What's the process? (187 comments)

In an extremely general sense:
Somewhere in the program the validation code will either pass or fail. This is done with a conditional branch instruction in the assembly. Crackers use a debugger to find where this branch is, then change it to an instruction that will always branch to the pass condition.

Of course there are countermeasures used, and sometimes crackers will be able to reverse-engineer the validation check to create a keygen, etc, but the general process is still to disassemble the executable and modify or inspect the validation check.

The Airplane of the Future May Not Have Windows

DMUTPeregrine Re:motion sickness (286 comments)

It can work both ways, but in the case of aircraft motion sickness it's most commonly that you feel motion but don't see it. Any disconnect between vision and inner-ear can cause motion sickness.

The Airplane of the Future May Not Have Windows

DMUTPeregrine Re:motion sickness (286 comments)

Yes, I was somewhat careless with my phrasing. Any disconnect between the inner ear's acceleration sense and that received from other senses can cause motion sickness. On aircraft, for most people (AFAIK), it's caused by feeling the acceleration with the ear and not seeing it with the eyes. For some, it gets reversed: they see too much movement out the window compared to what they feel, and so do better with aisle seats.

The Airplane of the Future May Not Have Windows

DMUTPeregrine Re:motion sickness (286 comments)

Other way around. It's when you sense an acceleration (inner ear) but don't see it that you get motion sickness. That's why looking out a window helps.

Dwarf Galaxies Dim Hopes of Dark Matter

DMUTPeregrine Re:Dwarf Galaxies Dim Hopes of WIMPS (137 comments)

Yep. If dark matter only interacts via gravity, and not via any of the other forces, then these results wouldn't constrain it. It would also mean that it's not going to be directly observable any time soon, so most scientists hope that's not the case, but it's certainly a possibility. Sterile neutrinos are one possibility for this.

Help ESR Stamp Out CVS and SVN In Our Lifetime

DMUTPeregrine Re:esr will save us! (245 comments)

Git is the best repository because it's the easiest to insult when something goes wrong. "Stupid git!" is a lot better than "Stupid CVS!"

Scientists Find Rats Aren't Smarter Than Mice, and That's Important

DMUTPeregrine Re:Intelligence isn't that important (154 comments)

You should try it with a lungfish. They're smart enough to breathe.

GlaxoSmithKline Released 45 Liters of Live Polio Virus

DMUTPeregrine Re:Homeopathy (209 comments)

Well, if you mean "destroyed the internal DNA payload and left only the outer protein shell" as being somehow equivalent to "watered down" then yes. But since the process has nothing to do with simple dilution that's not a very good comparison.

They're not writing to the filesystem, so that won't help.

Bash To Require Further Patching, As More Shellshock Holes Found

DMUTPeregrine Re:Bash is a very crappy programming language. (329 comments)

Batch search & replace just screams "Beta reduction of lambda calculus statements" to those who love Turing tarpits. Or perhaps Church tarpits in this case.

U2 and Apple Collaborate On 'Non-Piratable, Interactive Format For Music'

DMUTPeregrine Re:Expert. (358 comments)

Actually, 192kHz is the sample rate. That's a maximum of 96kHz output frequency.

The only point of such a sample rate is that it allows some audio modification techniques to have a lower distortion of the waveform in the audible spectrum range. It's very minor, far more of the effect comes from spending more money and the resulting placebo effect: the music sounds better and IS more pleasing, because the buyer thinks it should sound better. The effect on perception is real, even though the actual sound is identical to that of a cheaper system.

Farmers Carry Multidrug-Resistant Staph For Weeks Into Local Communities

DMUTPeregrine Re:Natural immunity (122 comments)

Hand sanitizer IS breeding antibiotic resistant bacteria. There are two kinds of sanitizer: The old alcohol-based ones, and the newer triclosan (an antibiotic) based ones. The triclosan sanitizers are often marketed as not drying out the skin, and so became popular. Resistance to triclosan tends to convey resistance to some other related antibiotics as well.

Alcohol based sanitizers are fine. Just use moisturizer after if you're worried about dry skin.

The FCC Net Neutrality Comment Deadline Has Arrived: What Now?

DMUTPeregrine Re:Spoilers (131 comments)

No. Net neutrality allows ISPs to follow the DS field, just not to set it on traffic they didn't create.

Of course, there's always the possibility of a legislature screwing it up and outlawing QoS, but redefinition of ISPs under FCC Title 2 wouldn't have that problem.
