GRIN Plasmonics: a Practical Path to Superfast Computing

"They said it could be done and now they've done it. What's more, they did it with a GRIN. A team of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley, have carried out the first experimental demonstration of GRIN - for gradient index - plasmonics, a hybrid technology that opens the door to a wide range of exotic optics, including superfast computers based on light rather than electronic signals, ultra-powerful optical microscopes able to resolve DNA molecules with visible light, and 'invisibility' carpet-cloaking devices."

Internet Infrastructure – Who Should Pay?

There is a falling out between governments & ISPs on the one hand and consumer groups and companies like YouTube and Netflix on the other. Lately more punitive measures affecting these companies and consumers have emerged that include increased throttling, greater per-usage billing and lower internet caps. The internet as whole is struggling to find a self-sustaining business model that supports the rising speed and bandwidth requirements of consumers and online media purveyors. The conflict boils down to who should pay and to what degree they should pay.

Future Transistors May Replace Silicon with Molybdenite

"Researchers in the field of microprocessors are always looking to the future to see what new materials are available as our chips get ever smaller, faster, and closer to the limits of current component manufacturing. While graphene is seen as a material of the future, it has recently been revealed that it may not be a suitable replacement for silicon in CPUs. This is due to graphene having a very small energy state gap, meaning when it is used as a transistor it cannot be turned off. There could be ways around such a limitation that haven’t been formulated yet, but we may not need graphene for processor manufacture after all. EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has discovered that molybdenite (MoS2) may be the perfect replacement for silicon."

Google Accuses Bing of Stealing Its Search Results

The web is already aflame with Google's accusation that Bing is stealing its search results. Google created code to manually rank certain bogus search terms, and ten created mock web pages as the top search results for these bogus terms. It turned out that Bing would list the exact same mock web pages as its top search result for these bogus terms. Google is unhappy with it, but in all honesty - since when is it wrong to copy in the computer business?

ARM Introduces Dual-Core Cortex-R5, R7 MPCore

"Processor design company ARM has today unveiled two new updates to its Cortex-R range of processors: the Cortex-R5 MPCore and the Cortex-R7 MPCore. While the Cortex-A processors can be found in mainstream consumer products such as cell phones and tablet devices, the Cortex-R chips are meant for deeply-embedded and system-on-a-chip duties. Notably you can find the last generation Cortex-R4 in hard disk drive controllers, wireless baseband processors, and automotive systems."

Intel Discovers Bug in 6-Series Chipset

"Intel just announced that it has identified a bug in the 6-series chipset, specifically in its SATA controller. Intel states that 'In some cases, the Serial-ATA ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives'. The fix requires new hardware, which means you will have to exchange your motherboard for a new one. Intel hasn't posted any instructions on how the recall will be handled other than to contact Intel via its support page or contact the manufacturer of your hardware directly."

Francis Ford Coppola: “Who Says Artists Have to Make Money?”

Francis Ford Coppola is one of the most prestigious and critically acclaimed directors in cinematographic history. He directed, among others, the Godfather trilogy and Apocalypse Now, and has won so many awards it's hard to keep track. In an interview with 99%, he touched on the subject of art and making money, and his musings are fascinating, and yet another indication that the times are changing in the content industry. "Who says artists have to make money?" Coppola wonders.

Pirate Bay, Decentralised P2P-DNS, ICANN

"I've always been a great fan of the law of unintended consequences. It takes you places. Unexpected places. Sometimes good, sometimes bad but never a dull moment. The recent kerfuffle over Pirate Bay is too well known to require detailed recounting here. What is really interesting though is where it might just eventually take us in terms of internet freedom. This article describes the one fallout of the legal judgements against Pirate Bay and how its response may unintentionally help to protect and promote internet freedoms."

Portable C Compiler Approaching 1.0

The BSD licensed Portable C Compiler (PCC) is steadily on the road for a 1.0 release and is now able to compile a FreeBSD/amd64 CURRENT system with almost no changes. The current version of PCC has evolved from the original PCC developed at Bell Labs during the 1970s and has been maintained by Anders Magnusson and a small team of developers during the last decade. It has received more attention during the last few years, especially by OpenBSD and NetBSD people seeing it at as a viable option as a GCC replacement.

Microsoft Asks Intel for a 16-core Atom Server Chip

"The Intel Atom processor line is associated with low power usage in devices such as a netbook or nettop computer. The emphasis is definitely not on performance, it's on pushing up battery life on a device with a small display and mid-range graphics requirements while still managing a decent desktop experience. Microsoft thinks Atom can do more, though, and wants to use it in servers. With that in mind it is calling on Intel to up the cores in an Atom chip to 16, and deploying it as a low power server chip solution."

McKusick Tells of the BSD Days As Only He Can

"The drought of those who speak without depending on slides has ended at the 12th Australian national Linux conference. Last evening, Marshall Kirk McKusick, a well-known BSD hacker, took those assembled down a slightly different track - after all, this is a Linux conference - with his narrative history of BSD. And what a rollicking ride it was! And the venue for his talk could hold only 100 people. He based his talk on notes he had made while travelling through Australia on a train in 1986 - he was a keynote speaker at the now-defunct Australian UNIX and Open Systems User Group conference in 1986."

Hobby OS-deving 1: Are You Ready?

It's recently been a year since I started working on my pet OS project, and I often end up looking backwards at what I have done, wondering what made things difficult in the beginning. One of my conclusions is that while there's a lot of documentation on OS development from a technical point of view, more should be written about the project management aspect of it. Namely, how to go from a blurry "I want to code an OS" vision to either a precise vision of what you want to achieve, or the decision to stop following this path before you hit a wall. This article series aims at putting those interested in hobby OS development on the right track, while keeping this aspect of things in mind.
