 ( anr | 2017. október 5., csütörtök - 20:27 )

Russian state hackers stole a collection of National Security Agency hacking tools and other documents from the personal computer of an agency contractor who had taken the classified documents home from work, reports The Wall Street Journal.

The reported breach took place in 2015 but wasn't discovered until spring of last year.

The Journal reports that the hackers identified the documents through Kaspersky Lab antivirus software.

trey jól vagy?

Éjjel 23 óra körül érkezett bejelentés arról, hogy egy győri lakásból furcsa, erős kábítószergyanús illat terjeng. A rendőrök kutyával mentek a helyszínre, ahol M. Gábor 35 éves helyi lakos nyitott ajtót.
A férfi elismerte, hogy a lakásában marihuánás cigarettát szívott, amire a rendőrök a kábítószer-kereső kutyával átkutatták a helyiségeket, és egy nejlonzacskóból meg egy kaspóból összesen 546,6 gramm kábítószergyanús anyagot foglaltak le.

Google reduces JPEG file size by 35%

New algorithm is based on human psychovisual system. Images look better, too.

Google has developed and open-sourced a new JPEG algorithm that reduces file size by about 35 percent—or alternatively, image quality can be significantly improved while keeping file size constant. Importantly, and unlike some of its other efforts in image compression (WebP, WebM), Google's new JPEGs are completely compatible with existing browsers, devices, photo editing apps, and the JPEG standard.

Szuperbiztonsagos datacenter: NY4

The 49 different exchanges that lease space at this data center sent a record 9.6 million messages per second through its fiber-optic cables in February. Every day, electronic trades representing trillions of dollars’ worth of equities, derivatives, currencies, and fixed-income assets pass under this roof. This is NY4. This is where Wall Street actually transacts.

Crossbar on the way to delivery terabyte on a chip nonvolatile 3D RRAM technology

 ( anr | 2014. július 3., csütörtök - 8:03 )

Crossbar announced it had demonstrated pre-production 1 megabyte arrays using its patented 1TnR (1 transistor driving n resistive memory cells) non-volatile resistive RAM (RRAM or ReRAM) for read/write operations. The company feels this is a major milestone toward commercializing terabyte-scale memory arrays on a postage-stamp-sized chip.

* 1 Terabyte of storage on a single chip
* 3D stacking on advanced nodes
* 20X faster write than NAND

Building a Warship for the Video Game Generation

 ( anr | 2014. július 1., kedd - 7:31 )

The Navy's latest high-tech destroyer is basically a floating Xbox.
The operations center aboard the new Zumwalt-class stealth destroyer is the ship's nerve center, into which sensor information flows, and from which the crew can control ship functions such as weapons and navigation. The Zumwalts are extremely automated, with a crew of just 130 sailors compared to more than 300 for the Navy's older and smaller Arleigh Burke-class destroyers .
That degree of automation is made possible by the extensive use of big video screens as well as touchscreen workstations.

Better data centers through machine learning

 ( anr | 2014. május 28., szerda - 12:34 )

It’s no secret that we’re obsessed with saving energy. For over a decade we’ve been designing and building data centers that use half the energy of a typical data center, and we’re always looking for ways to reduce our energy use even further. In our pursuit of extreme efficiency, we’ve hit upon a new tool: machine learning. Today we’re releasing a white paper (PDF) on how we’re using neural networks to optimize data center operations and drive our energy use to new lows.

Desert Bus is a trick minigame in the package, and was a featured part of Electronic Gaming Monthly's preview. The objective of the game is to drive a bus from Tucson, Arizona to Las Vegas, Nevada in real time at a maximum speed of 45 mph. The feat requires 8 hours of continuous play to complete, since the game cannot be paused.

Cunningham's Law

Cunningham's Law states, "the best way to get the right answer on the Internet is not to ask a question, it's to post the wrong answer."
People online generally don't want to be helpful, but they do want to be smartest person in the "room".
Best way to get answer about open source software:
Go to forum
"X software can't do Y task, and Z product can, how can it compete?"
5 ms later over a dozen answers calling you out with a detailed guide.
The Z part is important, otherwise you get one asshole that asks why you would want to do Y task and not something unrelated.

CodingBat is a free site of live coding problems to build coding skill in Java, and now in Python (example problem), created by Nick Parlante who is computer science lecturer at Stanford. The coding problems give immediate feedback, so it's an opportunity to practice and solidify understanding of the concepts. The problems could be used as homework, or for self-study practice, or in a lab, or as live lecture examples. The problems, all listed off the CodingBat home, have low overhead: short problem statements (like an exam) and immediate feedback in the browser.

The NSA's TAO hacking unit is considered to be the intelligence agency's top secret weapon. It maintains its own covert network, infiltrates computers around the world and even intercepts shipping deliveries to plant back doors in electronics ordered by those it is targeting.

Computers Can Be Hacked Using High-Frequency Sound

 ( anr | 2013. december 18., szerda - 13:22 )

Using the microphones and speakers that come standard in many of today's laptop computers and mobile devices, hackers can secretly transmit and receive data using high-frequency audio signals that are mostly inaudible to human ears, a new study shows.

Michael Hanspach and Michael Goetz, researchers at Germany's Fraunhofer Institute for Communication, Information Processing, and Ergonomics, recently performed a proof-of-concept experiment that showed that "covert acoustical networking," a technique which had been hypothesized but considered improbable by most experts, is indeed possible.
