You can actually see sound waves as they travel through the air thanks to a clever photographic trick! Great visualization.

lwn.net gets it right, once again!

"Proprietary software tends not to be followed by stories like this because the inevitable politics, profanity, and chair-throwing are kept behind closed doors and firewalls. We, instead, do most of it in the open — though flying furniture still tends to be an exceptional occurrence. These events can be fun to watch from a suitable distance and with enough popcorn. But they mean less than the hidden corporate disagreements that we never hear about — and much less than the public accomplishments that we almost never hear about. The 3.15 merge window, ongoing while this debate was happening, has seen (as of this writing) the merging of well over 10,000 changesets from 1100 developers, most of whom are working together smoothly. But none of the press accounts mentioned that."

Winner of most fascinating and most scary thing of the day: RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis by the S in RSA.

This was first discussed in 2004 but is now practical, not theoretical:

"Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away."

Mitigated in GnuPG 1.4.16 and 2.x via https://en.wikipedia.org/wiki/Blinding_(cryptography).

Makaleyi ciddiye alıp 1.x branch'ına blinding metodu eklemişler. Ben inanıyorum ve dehşete düşüyorum beyler, hadi görüşürüz.

Your Guide To When, Where and How To See The Aurora Borealis

As an amateur astronomer, two of the most frequently questions I’m asked are “When is the best time to see the aurora borealis and where is the best place.”

See Google what you did with the Reader. I liked code.google.com, but now I would never put something other than toys there, because it just might not survive your next spring cleaning. This is not about you trying to kill RSS, as pointless as it is, I don't care; this is about trust, and that is gone.

The First Image Ever of a Hydrogen Atom's Orbital Structure

What you’re looking at is the first direct observation of an atom’s electron orbital — an atom's actual wave function! To capture the image, researchers utilized a new quantum microscope — an incredible new device that literally allows scientists to gaze into the quantum realm.

An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a mathematical way of describing the fuzzy quantum states of particles, namely how they behave in both space and time. Typically, quantum physicists use formulas like the Schrödinger equation to describe these states, often coming up with complex numbers and fancy graphs.

Up until this point, scientists have never been able to actually observe the wave function. Trying to catch a glimpse of an atom’s exact position or the momentum of its lone electron has been like trying to catch a swarm of flies with one hand; direct observations have this nasty way of disrupting quantum coherence. What’s been required to capture a full quantum state is a tool that can statistically average many measurements over time.

Google Now can't calculate dates past the end of 32-bit Unix time.

Note how it can add 25 years from today, but not 30.

Softwarelol.

In partnership with the Arduino project popular among hobbyists and students, Intel will sell small computer systems with its 32-bit Quark chip. Read this article by Stephen Shankland on CNET News.

This was great. Part high-level algorithms description, part magic show.
