Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?

Since its announcement, there's been very few details about game play aside from the DCPU-16 and art tests. But in this interview, Notch has revealed quite a bit about how the game will function and non-final ideas he has for either a monthly fee to play in a 'multiverse' or micropayments. He talks about a custom OS people are working on to load into the game's CPU as well as a an in-game 3D printer that will allow you to make virtual objects. When asked about Kickstarter and his Oculus dev kit, Notch said 'Definitely going to make it work in 0x10c no matter what' and his account of using the Oculus Rift sounds more than promising for the VR Device. When asked about Linux he said, '[Linux] is wonderful. I think we need to have it, and it’s a shame that more people, including myself, don’t use it. It’s gotten easier and friendlier.' When asked about Microsoft he said, 'I use their OS – Windows 7 is an amazing operating system in my opinion and of course there’s the Xbox, which I love. I’m sure Bing is going to take off and save them. [Editor’s note: Notch is smiling mischievously as he says this.]'

They go into some nice detail about the strategy for extracting this data from a discarded unit and noticing structure. There's also other data that they weren't able to identify which causes one to wonder how many other Easter eggs are lying about in various ROM chips and what modern Easter eggs must be shipping with software/hardware today.

From Algotochip: "We can move your designs from algorithms to chips in as little as eight weeks," said Satish Padmanabhan CTO and founder of Algotochip, whose EDA tool directly implements digital chips from C-algorithms." Padmanabhan is the designer of the first superscalar DSP. His company, interestingly enough, claims to provide a service that consists of a 'suite of software tools that interprets a customers' C-code without their having any knowledge of Algotochp's proprietary technology and tools. The resultant GDSII design, from which an EDA system can produce the file that goes to TSMC, and all of its intellectual property (IP) is owned completely by the customer—with no licenses required from Algotochip.' This was presented at this year's Globalpress Electronics Summit. Too good to be true or can we expect our ANSI C code to be automagically implemented in a SoC in such a short time?

Particularly exciting about this research is that it integrates the fabrication of III-V devices into our existing infrastructures. From the article, 'Once the nanopillar was made, the researchers showed that it could generate near infrared laser light – a wavelength of about 950 nanometers – at room temperature. The hexagonal geometry dictated by the crystal structure of the nanopillars creates a new, efficient, light-trapping optical cavity. Light circulates up and down the structure in a helical fashion and amplifies via this optical feedback mechanism.' The principal investigator of the research said it has the 'potential to catalyze an optoelectronics revolution in computing, communications, displays and optical signal processing.' This research was funded by DARPA and the DoD.

To commemorate the 65th anniversary of the founding of the ruling Workers' Party of Korea, North Korea will no longer depend on Chinese national internet service to reach the outside world — they have their own connection and are hosting sites like the state run media. The article mentions that about a thousand websites are coming online including services like Skype and Twitter. From where I sit in the United States, I can't seem to get any.kp TLD sites to resolve but the news is promising if in fact it will bring more information to the information starved masses of North Korea.

Their backup cooling (Loop B) is functioning as designed and NASA released an official statement, "The crew is in no danger, but will need to work additional troubleshooting on Sunday to keep the station in a stable configuration, including the installation of a jumper cable to maintain proper cooling to the Zarya module in the Russian segment."

A professional astronomer who purchased one with the intent of making music out of the solar sensor described the kit, 'It has a power system that's basically two lithium AA batteries hooked together, a little stick of gum computer chip, a bunch of very fragile solar cells that are packed away, antenna and lots of wires. If you were expecting to see Sputnik, it's completely different.' However, it appears that whatever you could fit inside the shoebox sized "launch cylinder" could go up (no weight limits listed). The TubeSat Kit suggests many possible uses and experiments including 'Earth-from-space video imaging, Earth magnetic field measurement, Satellite orientation detection (horizon sensor, gyros, accelerometers, etc.), Orbital environment measurements (temperature, pressure, radiation, etc.), On-orbit hardware and software component testing (microprocessors, etc.), Tracking migratory animals from orbit, Testing satellite stabilization methods, Biological experiments, On-orbit advertising, Private e-mail, Space art and even Space burials.' Considering how easily some have made image satellites, there might be a lot of uses for amateur and professional alike.

A petition is claiming that "Foxconn's military management model, including scolding and sometimes beating front-line workers, helps drive isolated Chinese workers to kill themselves. If the company does not put an end to that, there will be more suicides in the future." Chairman Terry Gou has responded that dormitories and rec facilities have been built for workers in China as well as Foxconn provided social services that the local government cannot provide to the many factory workers. As a result, Gou went on to reveal that it's Chinese plant operations may be unsustainable (possibly as a result of the aforementioned benefits cost). Some workers are seeing raises with this article mentioning monthly wages have DOUBLED to $239 at the Chinese factories. You should only be bothered with accusations of Foxconn's "concentration camp styled controlling system" if you care about how humane the conditions are for the hands that manufactured your HP/Dell/Apple devices and the related subcomponents.

The founder of Sennheiser and its namesake was responsible for the first shotgun microphones and open headphones as well as advancements in wireless radio and infra-red transmission. A pair of 457s has served me at work for over five years in various cubicle lands and despite all the abuse they've endured they are still producing great sound. Rest in piece, Fritz.
eldavojohn writes: In a disturbing case for average consumers, nine DRAM chip manufacturers have been fined over four hundred million dollars for price fixing. The named companies are Samsung, Hynix, Infineon, NEC, Hitachi, Mitsubishi, Toshiba, Elpida and Nanya. Micron, a tenth price fixing member, avoided fines for reporting the other nine to the authorities. Since all companies cooperated with the probe, they received a 10% reduction in fines so it could have been worse. The US DoJ has had their own history with chip makers as well as LCD makers in price fixing scandals.
