Yes! The first batch of Raspberry Pi boards is finally shipping out to customers around the world. It's been a long journey (ugh), but at least we'll be seeing reviews and videos now. My Pi is still on backorder, so no review on OSNews just yet.

Not being content with the state of open source graphics drivers for Linux, a developer working for Texas Instruments has reverse-engineered his competitor's (Qualcomm) driver and written an open-source Snapdragon driver. With being tainted by legal documents at Texas Instruments, the developer who is also involved with Linaro, had no other choice but to work on an open source graphics driver for his competitor in his free time. The open source Qualcomm Snapdragon/Adreno driver is called Freedreno.

Very sad news indeed. Jack Tramiel, founder of Commodore International and the man behind Atari, has passed away this past weekend. At 83, he passed away, surrounded by family and friends. People like this don't come in dozens, so we lost one of the great men of computing.

"This article CPU DB (cpudb.stanford.edu), an open and extensible database collected by Stanford's VLSI (very large-scale integration) Research Group over several generations of processors (and students). We gathered information on commercial processors from 17 manufacturers and placed it in CPU DB, which now contains data on 790 processors spanning the past 40 years. In addition, we provide a methodology to separate the effect of technology scaling from improvements on other frontiers (e.g., architecture and software), allowing the comparison of machines built in different technologies."

For years and years now (since the first G4 iBooks), whenever someone asked me for advice about what laptop to buy, my standard answer was simple: get an Apple laptop. Doesn't matter which one. Apple was so far ahead of the competition it just wasn't funny anymore. This past weekend, though, marked the end of an era for me: for the first time, I advised someone to get an Asus ZenBook instead.

"In the world of hard drives storage, density is king and Seagate has just achieved a major breakthrough that guarantees major storage gains for the next decade. That breakthrough is managing to squeeze 1 terabit (1 trillion bits) of data into a square inch or space, effectively opening the way for larger hard drives over the coming years beyond the 3TB maximum we currently enjoy. How much of an improvement does this storage milestone offer? Current hard drives max out at around 620 gigabits per square inch, meaning Seagate has improved upon that by over 50%. However, that's just the beginning."

The Cortex -M0+ architecture is designed to provide chip-makers with the means to build microcontrollers that require "ultra low power" but are capable of 32-bit processing. Arm says it went back to the drawing board to create the new processor cores which measure 1mm by 1mm in size. It says the microcontrollers should draw around a third less energy than their predecessors, which only offered 8 and 16-bit capabilities.

"After struggling with this issue for well over a year and really pushing hard to track it down in the last two months I was finally able to come up with a test case running 'cc1' from gcc-4.4 in a loop and get it to fail in less than 60 seconds. Prior to finding this case it would take anywhere up to 2 days with 48 cores fully loaded to reproduce the failure. AMD confirms. '...it isn't every day that a guy like me gets to find an honest-to-god hardware bug in a major cpu!'"

This morning, I experienced the nerd equivalent of a Black Friday $50 iPad sale. At 07:00 CET, the first batch of the much-anticipated Raspberry Pi went on sale, and while Raspberry Pi itself was very properly prepared, the two large international retailers actually selling the device weren't - despite warnings from Raspberry Pi about the enormous amount of traffic that would come their way, the two sites crumbled to dust within seconds. There's good news too - the cheaper model A has seen its RAM doubled at no additional cost.

Current computers use SATA disk drives. Pentium IV's and earlier computers used the IDE drive standards. How can you intermix SATA and IDE disk drives? This article discusses the options. It is the next in my series of articles on computer refurbishing.

"A group of researchers has fabricated a single-atom transistor by introducing one phosphorous atom into a silicon lattice. Through the use of a scanning tunnelling microscope and hydrogen-resist lithography, Martin Fuechsle et al. placed the phosphorous atom precisely between very thin silicon leads, allowing them to measure its electrical behavior. The results show clearly that we can read both the quantum transitions within the phosphorous atom and its transistor behavior. No smaller solid-state devices are possible, so systems of this type reveal the limit of Moore's law - the prediction about the miniaturization of technology - while pointing toward solid-state quantum computing devices."

No matter where you look these days, there's a profound sense here in the west that the people no longer having any tangible control over what our governments do. Sure, we are allowed to vote every once in a while, but effectively, most of our countries are governed by backroom deals and corporate interests. If matters really do get out of hand, how do we fight this? Well, with technology of course!

Big news from the Raspberry Pi front today - they have a manufacturing date. "The boards will be finished on February 20. Eben and I may be going to China to make sure that the boards can be brought up properly for that date if necessary. We'll be airfreighting them to the UK immediately, so you should be able to buy them before the end of the month."

When the Raspberry Pi ships later this year, it will be delivered to your door as a finished unit. The more adventurous tinkerers among you, as well as adept system builders, have asked the Raspberry Pi Foundation why they can’t get them in kit form instead. The reason why that wasn’t considered is demonstrated in an image released by Broadcom . . . they are tiny. And unlike a typical system build using an x86 chip that just slots into place, installing these chips requires a very steady hand and just the right amount of solder.
