Rethinking the Wetsuit

MasterPatricko Re:Another advantage (153 comments)

I've heard humans taste bad (c.f. animals that take a bite of humans spit us out / don't take another one) and we're probably not very efficient meals compared to fatty seals or muscley fish, so I doubt there is any evolutionary advantage to sharks becoming better human predators.

Digia Releases Qt 5.1 With Preliminary Support For Android and iOS

MasterPatricko Re:It's the promises you have to look out for (86 comments)

Qt is publicly developed on Gitorious (https://qt.gitorious.org/), accepting merge requests (with code review). Even if you can't get them to accept patches into the 'official' codebase, you could always just branch it and fix the bugs for yourself ...

Are You Sure This Is the Source Code?

MasterPatricko Re:Bogus argument (311 comments)

On Linux packages (rpm, deb) are almost always signed by a distribution key, which needs root access to accept.
On Windows binary signing just gives you a company name associated with the exe, which I think is regularly ignored by users ...

New In-Memory Rootkit Discovered By German Hoster

MasterPatricko Re:Kinda cool that they found it (91 comments)

If you're serious about computer security you bring the analysis tools with you, from an independent known-good source, not using anything from the possibly-compromised machine.

No, the Tesla Model S Doesn't Pollute More Than an SUV

MasterPatricko Re:Same as last time (559 comments)

Small fuel efficient cars have a huge problematic bug , that has never been worked out. They're dangerous, hard to spot, slow to get out of the way

As evidenced by your own statement it's the huge speeding behemoths that are actually the ones causing the accidents, even if it's those around them that suffer the consequences ... and yet you claim it's the small cars that should be removed from the road?

Particle Physicists Confirm Arrow of Time Using B Meson Measurements

MasterPatricko Re:What this means (259 comments)

A symmetry under X means the system under test is unchanged (ie the same physical laws work, your predictions are still correct) when you do X.

A simple example is the symmetry under spatial translation -- if your experiment still behaves the same way if it's moved a meter to the left, it has "spatial translational symmetry". This symmetry isn't exactly true on the surface of the earth because of variations in the gravitational field etc., but on a small scale for lab experiments it's true, and in deep space it's certainly true. Another example is symmetry under spatial rotation -- your experiment doesn't care whether you face it north or east.

By a very cool bit of maths called Noether's Theorem, you can show that for every symmetry that a system has, there is an associated conserved quantity. So systems with spatial translation symmetry will show conservation of momentum. Systems with time translation symmetry exhibit conservation of energy -- within that system, you can't create or destroy energy. Rotational symmetry results in conservation of angular momentum.
https://en.wikipedia.org/wiki/Symmetry_(physics)

Much of modern physics is built around identifying the symmetries that the universe (or parts of the universe) obeys, the associated conserved quantities, and what happens when those symmetries are broken -- for example the maths leading to the Higgs boson. Currently we believe the universe overall obeys C(harge) P(arity) T(ime) symmetry, that is if you change matter for antimatter, flip everything spatially (as in a mirror), and reverse the direction of time, everything would be the same. This recent experiment shows that time symmetry by itself is not obeyed -- if you only reverse the direction of time, this particular particle collision is not the same.

Particle Physicists Confirm Arrow of Time Using B Meson Measurements

MasterPatricko Re:Quick question then (259 comments)

Photons moving through a medium are "slowed down" by interactions of the electromagnetic field with the atoms of the medium.

Remember that a photon is just localised electromagnetic energy. In a medium, the electromagnetic fields behave differently than in a vacuum, because of the all the atoms with their various charged bits (protons, electrons) -- there is a different "resistance" to changing the field strength because the field has to move the atoms as well. This resistance to changing the field strength is what determines the speed of the electromagnetic wave.
In mathematical terms we say photons (electromagnetic waves) travel at speed c/n, where n is the refractive index of the material, and n is sqrt(epsilon * mu), where epsilon and mu are the relative permittivity and permeability (to electromagnetic fields) of the medium.

A simpler, but wrong, model you might hear is that the photons are being absorbed and reemitted many times as it passes through the medium, all while travelling at c between the atoms, but that can't be really true because otherwise light would be highly directionally spread out after exiting any high refractive index material, but we can see straight through glass and water.

Judge Grudgingly Awards $3.6 Million In DRM Circumvention Case

MasterPatricko The real reason the judge was annoyed (227 comments)

Instead, Plaintiff merely submitted 252 raw pages of documents obtained through discovery without so much as a summary of the information contained in those documents or an explanation to the Court how any of the line items contained therein directly relate to Kumar’s UMaple activities.

Seems to me that's the real reason the judge wasn't feeling like awarding any more damages, not some kind of protest against the DMCA or statutory damages.

Did Life Emerge In Ponds Rather Than Ocean Vents?

Listen, strange chemicals lyin' in ponds distributin' ions is no basis for a system of life. Supreme biological diversity derives from a mandate from the creator, not from some farcical aquatic ceremony!

Oh! Come and see the violence inherent in the system! Help! Help! I'm being repressed!

How To Catch a Laptop Thief?

MasterPatricko Re:Violence (485 comments)

Contrary to popular belief, violence is the solution, If you are sure you know who it is, go to town on them. Give me a baseball bat and 5 minutes with any cocksucker that steals my shit, and he'll wish he didn't. Sure you might have my laptop, but I just knocked out all of your teeth and broke your legs. Fair trade.

Hmm. Your ideas are intriguing to me and I wish to subscribe to your newsletter.

Essentially, opposite of the effect of helium on the vocal tract. It's way denser than air so you end up with a deep-sounding voice.

A Linux Kernel More Stable Than -stable

MasterPatricko Re:What will this do to version numbering? (142 comments)

"this guy" is Greg K-H, second-in-command to Linus and the maintainer of the -stable tree. His arguments were one of the main reasons Linus changed the 3.0 numbering. Greg is just proposing that he maintains another tree officially, not a "fork".
As for version numbering, I think there will be 3 numbers - first two for mainline releases, and one more for stable/longterm patch level. I don't think -longterm will be needing an extra number.

Next Linux kernel version to be 3.0

MasterPatricko MasterPatricko writes  |  more than 3 years ago

MasterPatricko (1414887) writes "After the discussion about kernel version numbering last week (also discussed here), it's official: the next kernel release will be version 3.0. There are actually no significant changes (Linus hasn't rewritten the kernel in Visual Basic), but it was decided now — almost 20 years since the first release — was as good as any time to change the numbering. In a change from the 2.6 series, the third number will only be used for -stable numbering (so the next release after this one will be 3.1, not 3.0.1). Now we wait to see who gets the honour of first breaking the Linux 3.0 tree! And everyone who wrote scripts specifically checking for the "2.6" string — time to get to work fixing that ..."

New laser data transfer rate record set at 26 Tbps

MasterPatricko MasterPatricko writes  |  more than 3 years ago

MasterPatricko (1414887) writes "Scientists at the Karlsruhe Institute of Technology (KIT), Germany have published a technique to push optical data transfer rates to new levels.
"We demonstrate an optical fast Fourier transform scheme that provides the necessary computing power to encode lower-bitrate tributaries into 10.8 and 26.0 Tbit s-1 line-rate data streams ... To the best of our knowledge, this is the largest line rate ever encoded onto a single light source."
Slashdot readers may find it useful to know that 26Tbps is approximately 0.1 Libraries of Congress per second.
