In networking, an air gap refers to a security measure that separates a network from the public infrastructure, either physically or through the use of extremely secure tunnelling. This prevents access to that network over the internet or less secure LANs and is used in high security locations as it is generally considered one of the best ways of securing a network. As with all things silicon, it is not perfect and this article at The Register should not be read by the faint of heart. They describe several methods which have been developed to overcome air gaps, thankfully most require that the attacker had been able to gain physical access to the air gapped systems to infect them from within and as you have heard many times, once an attacker can gain physical access to your systems all bets are off.
What is interesting is the ways in which the infected systems transmit the stolen data without the need for physical contact and are incredibly difficult to detect. Some are able to use the FM frequencies generated by GPUs to send data to cellphones up to 7m away while another uses the pixels to transmit hidden data in a way that is invisible to the user of the machine. Other attacks involve spreading infection via microphones and speakers or a thumbdrive which was attached to an air gapped machine which could transmit data over a radio frequency up to 13 kilometres away. It is a wild world out there and even though many of the attacks described have only been done in research labs; don't let strangers fondle your equipment without consent!
"The custom code had jumped an air gap at a defence client and infected what should have been a highly-secure computer. Sikorski's colleagues from an unnamed company plucked the malware and sent it off to FireEye's FLARE team for analysis."

Update: Fixed the title of "Pikmin". Accidentally wrote "Pikman".
Considering the recent Nintendo license requirements, I expect that their demonstrative YouTube videos will have a difficult time staying online. Regardless, if you are in a jurisdiction where this is legal, it is now possible to play some Gamecube-era games at 60 FPS (as well as 1080p) with an emulator PC.
The blog post at the Dolphin Emulator's website goes into the “hack” in detail. The main problem is that these games are tied to specific framerates, which will cause problems with sound processing and other, time-sensitive bits of code. I have actually been told that one of the most difficult aspects of bringing a console game to the PC (or restoring an old PC game) is touching the timing code. It will break things all over. For Super Mario Sunshine, this also involves patching the game such that certain parts are still ticked at 30 FPS, despite the render occurring at twice that rate.
Also interesting is that some games, like Super Smash Bros. Melee, did not require a game-side patch. Why? Because they apparently include a slow-motion setting by default, which was enabled and then promptly sped up to real time, resulting in a higher frame rate at normal speed. The PC is nothing if not interesting.

Tagged: raspberry pi 2, Raspberry Pi
It did not take long to find a problem with the Raspberry Pi 2. As it turns out, the Pi 2 contains a power regulator chip that is susceptible to bright sources of light. The light will force electrons to move when a metal is struck by enough photons with the correct, per-photon energy, which is its frequency/color, and that will be perceived as a voltage (because it actually does cause a voltage).
In the Raspberry Pi 2, this manifests as a voltage drop and the device immediately powers down. This was first discovered by Peter Onion on the Raspberry Pi forums while he was taking photographs of his Raspberry Pi 2. He noticed that each time he snapped a photo, the Pi would shut down. Liz Upton of the Raspberry Pi Foundation promptly confirmed the issue and wrote a long blog post explaining what actually happens. She borrows Peter's joke from the forum thread, that the Pi 2 is camera shy, and explains that “everyday light sources” will not cause this to happen. She then explains the photoelectric effect, the role of the above pictured U16 chip, and the issue itself.
I definitely appreciate Liz Upton and the Raspberry Pi Foundation, founded on the premise of education, taking the time to explain their bugs from an educational standpoint. That said, it is easy to lose sight of your goal when you have a product to defend, and I am glad that it did not get in the way.
A final note: this will not damage the Pi 2, just cause it to crash and power down. The only real problem is that shutting down your device mid-task will crash your task. If that is a write to the SD card, that will likely corrupt that write.

USB 3.0, for storage, is fast. If you are using an external, spindle-based hard drive, it will perform basically as fast as an internal sibling would. Apart from my two SSDs, I do not even have an internal drive anymore. You can safely install games to external hard drives now.
But with USB 3.1, the spec doubled to 10 Gbps, which matches the first generation Thunderbolt connector. A couple of weeks ago, Tom's Hardware put it to the test with an ASMedia USB3.1 to SATA 6 Gbps developer board. Sure enough, when you are raiding a pair of Intel 730 SSDs, you can achieve over 700 MB/s read/write in CrystalDiskMark.
About the most interesting part of Tom's Hardware testing is their CPU usage benchmark. While USB 3.0 on Intel's controller choked a CPU thread, USB 3.1 on ASMedia's controller did not even reach half of a thread's maximum (the CPU in question is a Core i7-5930K Haswell-E at 3.5 GHz).
So until we get flash drives that are constrained by USB 3.0's fairly high ceiling, we might be able to have reduced CPU usage.

When we report on Cherry Corp, it is usually about their mechanical switches that are the basis (until just recently) of most mechanical keyboards. They also make full keyboards, including non-mechanical varieties, although they are usually designed for enterprise customers. This one is likely intended for that audience.
Simply put, The Cherry JD-0400EU is a wireless keyboard and mouse combo that encrypts all traffic with 128-bit AES encryption. If you are wondering why no-one else thought to do this? They did. Even Logitech has a whole line-up of 128-bit AES-encrypted mouse and keyboard combos. This is not even a feature that is only filled by niche companies.
Still, making sure people know that your wireless peripheral is encrypted will probably let you access a whole new audience of government, enterprise, and health care customers. The keyboard itself is based on scissor-switches, which are those non-removable keys that you find on many laptops. They are not high-performance, but they can be quite thin and low-profile. The switch mechanism under the scissor struts is membrane-based.
Pricing and availability are not yet listed.

This is just a quick note for a small subset of our audience. If any of our developer-minded readers are in the Phoenix, Arizona region on February 19th, Intel will be hosting a meetup at UAT (the University of Advancing Technology). The processor vendor will perform a technical presentation about the Edison Internet-of-Things (IoT) developer kit. Shortly after the presentation, the group will move to Aunt Chilada's for a social event.
The presentation will take place in the theatre (there is only one as far as I can tell) at 6:30pm. Admission is free and there will be 10 Intel Edison kits to be raffled. Food and beverages will be provided by Intel (at Aunt Chilada's restaurant).

Or is that Left Shark Eggs? Yup, pay attention near the end of the post for an Easter Egg.
Every year, Google hosts their I/O developer conference, which often involves the launching of new hardware and services. This year, it will take place on May 28th and May 29th. Registration to register will open on March 17th at noon ET and it will end on the 19th. If you do not get in, many keynotes and sessions will be broadcast over the internet... because it's Google.
Note how I said “Registration to register”? That was not a typo. You are putting your name into a randomizer that will select candidates to actually register and purchase their tickets. Last year, tickets sold out in less than an hour. Apparently Google believes that it is better for the tickets to go to the luckiest individuals, rather than the best F5ers.
I hope this made your day as bright as mine. Basically, I HOPE I RUINED YOUR DAY TOO!

Battlefield Hardline is in public beta for those who have tired of Battlefield 4 and are looking for a new online Frostbite 3 shooter to play and [H]ard|OCP has run benchmarks to show you what kind of performance you can expect. They gathered together three cards from the two companies, a GTX 980, 970 and 960 as well as an R9 290X DD, 290 and 285 with a mix of default and factory overclocked frequencies. As of yet there is no Mantle support in the beta so both vendors are using DX11 in the tests, with the top four cards at 2560x1440 and the remaining two at 1080p, all set to 4X MSAA and Ultra settings except for the Dustbowl map. The GTX 980 takes top spot but the most interesting results are the 290X and 970; the difference is so minuscule that they essentially perform at the same level and the same can be said of the pricing. Also worthy of note is that in only one test did the cards use more than 3GB of RAM and never hit 3.5GB.
"We hopped on the open public beta of Battlefield Hardline this past week and tested performance in all three maps with six video cards to find out how this game performs. We will talk about each map in the beta, and our experiences in terms of performance and gameplay experience so that you will know what to expect in the full game."
