By contrast, they say that with a 5 metres telescope, synthetic tracking should spot about 80 of these objects each night. That’s “almost 1000 times higher than the discovery rate of these small objects over the last 5 years,” they say.
But there are other uses for this data. NASA is hoping to send a crewed mission to a near Earth asteroid in the not-too-distant future and has started a program called the Asteroid Grand Challenge to identify potential targets.
Paper on this subject here.
One thing these platforms have in common is an ARM processor. Now they have some competition from Intel with its “MinnowBoard,” a $199 computer in the form of a 4.2″ x 4.2″ board with an Intel Atom processor.
via $199, 4.2” computer is Intel’s first Raspberry Pi competitor | Ars Technica.
MinnowBoard uses a 5V/2.5A power supply. Other specs are as follows:
- Intel Atom E640 CPU (1.0GHz, 32-bit with Hyper-threading and Virtualization Technology)
- Integrated Intel Graphics Media Accelerator (GMA) 600
- PCI Express
- SATA2 3Gbps
- Gigabit Ethernet
- >MicroSD
- USB
- UEFI Firmware
- 1GB DDR2 RAM<
- 8 GPIO pins
- 2 GPIO-controlled LEDs
- 4 GPIO switches
Wi-Fi client devices can seek a wireless network to connect to through active or passive scanning for ‘beacons’ broadcast by access points. Smartphones typically use active scanning, which means they switch on their wireless radio for a brief period to send a probe request and receive information about networks within range. The operating systems of wireless devices can include a preferred network list (PNL), which incorporates some of the SSIDs of Wi-Fi networks the device has previously successfully connected to, and some devices will include this information in their probe requests.
The attack against the Ivy Bridge processors sabotages random number generator (RNG) instructions Intel engineers added to the processor. The exploit works by severely reducing the amount of entropy the RNG normally uses, from 128 bits to 32 bits. The hack is similar to stacking a deck of cards during a game of Bridge. Keys generated with an altered chip would be so predictable an adversary could guess them with little time or effort required. The severely weakened RNG isn’t detected by any of the “Built-In Self-Tests” required for the P800-90 and FIPS 140-2 compliance certifications mandated by the National Institute of Standards and Technology.

Most of Brazil’s global Internet traffic passes through the United States, so Rousseff’s government plans to lay underwater fiber optic cable directly to Europe and also link to all South American nations to create what it hopes will be a network free of U.S. eavesdropping.

It cited a “common understanding” between Brazil and the European Union on data privacy, and said “negotiations are underway in South America for the deployment of land connections between all nations.” It said Brazil plans to boost investment in home-grown technology and buy only software and hardware that meet government data privacy specifications.

Solar array deployment is complete for Orbital Sciences Corp.’s Cygnus spacecraft, now traveling 17,500 mph in Earth’s orbit to rendezvous with the International Space Station on Sunday, Sept. 22, for a demonstration resupply mission. The spacecraft will deliver about 1,300 pounds (589 kilograms) of cargo, including food and clothing, to the space station’s Expedition 37 crew, who will grapple and attach the capsule using the orbiting laboratory’s robotic arm.
These days, most applications running on virtual machines in the cloud run on top of Linux. We all love Linux, but as an all-encompassing operating system for everything from phones to supercomputers, Linux was never really designed for virtual machines; It is big and complex, and it offers features (such as multi-user and multi-process) which are today made redundant by the hypervisor and slow it down. Linux’s APIs are many times set in stone by decades of legacy code. All these cost in application performance, and make it harder to innovate.
This is why we developed OSv, a new operating system designed to run a single application on a virtual machine. As it runs a single application there is no need for kernel-userspace isolation, reducing context switch costs and unnecessary copying. A design from scratch allowed us to experiment with new ideas like lock-free mutexes (solving the Lock-Holder Preemption problem that plagues operating systems on virtual machines), extremely fast context switches, Van Jacobson’s network channels (see http://www.lemis.com/grog/Documentation/vj/lca06vj.pdf), and more. Also, OSv is released under the more permissive BSD license (not GPL like Linux), is tiny compared to Linux, and takes less than one second to boot and start the user’s application.

The WiFi deployment plays a dual role for Virgin Media Business, however. The company uses fiber backhaul connections to ensure the network’s performance, but also to lease to mobile operators that can use it to bolster their 3G and 4G networks. It’s a win-win for everyone: Residents get free WiFi, Virgin gets access to prime real estate for small cells, and the city gets a cut of the revenue it earns from the wireless operators.

Falcon UAV is a Colorado company that makes a fixed-wing UAV called a Falcon that uses GPS and cameras to autonomously generate among other things highly accurate maps of the ground. The UAV is hand-launched, with an endurance of about an hour, and generally operates between 300 and 1,500 feet above the ground. It has public safety flight approvals from the Federal Aviation Administration FAA to fly in some parts of Colorado. Basically, the point here is that we’re not talking about some random dude with a quadrotor flying around taking pictures: the Falcons are designed for and governmentally approved for mapping missions in public airspace.
