Our Planned Approach to Secure Boot

At the implementation layer, we intend to use the shim loader originally developed by Fedora – it’s a smart solution which avoids several nasty legal issues, and simplifies the certification/signing step considerably. This shim loader’s job is to load grub2 and verify it; this version of grub2 in turn will load kernels signed by a SUSE key only. We are currently considering to provide this functionality with SLE11 SP3 on fresh installations with UEFI Secure Boot present.

The underground economy of social networks

In a new study, Barracuda Labs analyzed a random sampling of more than 70,000 fake Twitter accounts that are being used to sell fake Twitter followers.

This underground economy consists of dealers who create and sell the use of thousands of fake social accounts, and Abusers who buy follows or likes from these fake accounts to boost their perceived popularity, sell advertising based on their now large social audience or conduct other malicious activity.

Content-Centric Networking

CCN directly routes and delivers named pieces of content at the packet level of the network, enabling automatic and application-neutral caching in memory wherever it’s located in the network. The result? Efficient and effective delivery of content wherever and whenever it is needed.  Since the architecture enables these caching effects as an automatic side effect of packet delivery, memory can be used without building expensive application-level caching services.

This is What Wall Street’s Terrifying Robot Invasion Looks Like

HFT affects all investors to an extent, because stocks are now priced differently than in the past. The market used to consist mostly of investors analyzing cash flows and balance sheets, trying to calculate a company’s fair value. HFTs, on the other hand, react to movements in stock prices alone. That is not necessarily a bad thing, but since HFTs are responsible for two-thirds of the trading volume, we have the strange situation where they can set the price based on what they perceive others’ perceptions to be.

Could an SRAM Hourglass Save RFID Chips Just in Time?

The clock operates over spans of seconds to minutes after an RFID chip is charged up from an RFID reader or other ambient radio-wave energy. As a result, even after the radio signal is removed, the clock endows the RFID chip with the ability to know when its security keys may be in danger.

via Could an SRAM Hourglass Save RFID Chips Just in Time? – IEEE Spectrum.

Having a clock can be very useful in defending against brute-force attacks that may try to guess the chip’s passwords hundreds or thousands of times per second. A TARDIS-enabled chip—requiring no new hardware and representing fewer than 50 lines of additional code—would receive a power-up from, say, a nearby RFID reader. Instead of wiping the SRAM clean, the device would first read off the state of the SRAM, which would be partially decayed from the last time the chip was powered up. Comparing the percentage of decayed bits to a precompiled table would enable TARDIS to read off the time elapsed since the previous power-up.

NASA – Curiosity Lands on Mars

NASA’s Curiosity rover has landed on Mars! Its descent-stage retrorockets fired, guiding it to the surface. Nylon cords lowered the rover to the ground in the “sky crane” maneuver. When the spacecraft sensed touchdown,…

The sheer size of the Mars Science Laboratory rover (over one ton, or 900 kilograms) would preclude it from taking advantage of an airbag-assisted landing. Instead, the Mars Science Laboratory will use the sky crane touchdown system, which will be capable of delivering a much larger rover onto the surface. It will place the rover on its wheels, ready to begin its mission after thorough post-landing checkouts.

Development Release: Damn Small Linux 4.11 RC1

Nearly four years after the last stable release, the Damn Small Linux distribution is once again being actively developed. Yesterday John Andrews announced the availability of the first release candidate version 4.11: “Here is the first release candidate for Damn Small Linux DSL 4.11. The changes in this release are a step toward making DSL a friendly alternative for older hardware. I’ve fixed some bugs, updated some applications, and replaced others.

Apple patent filing looks a lot like Microsoft Surface

A patent application submitted by Apple last year — and made public just this morning — describes a flexible, magnetically attached cover for a tablet device. It’s similar to Apple’s existing smart cover for the iPad, except that this cover can also function as an input and display device. And one of the concepts described by Apple in the patent filing is an idea for using the cover as a keyboard.

The end result looks very similar to the signature feature of Microsoft’s Surface tablet computer.
