"Disassembling Apple's diminutive inch-cube iPhone charger reveals a technologically advanced flyback switching power supply that goes beyond the typical charger. It simply takes AC input (anything between 100 and 240 volts) and produce 5 watts of smooth 5 volt power, but the circuit to do this is surprisingly complex and innovative." Quite fascinating, although I'm not sure just how much the mentioned advantages really matter beyond bragging rights.

"As the Raspberry Pi started to ship the Sinclair ZX Spectrum turned 30 years old, and comparisons were being made between the two and their role in providing access to affordable computer hardware. Given the phenomenal advances in computing since the birth of the ZX Spectrum, I thought it might be fun to compare the Raspberry Pi with a computer that was closer to the state of the art at around that time, and to see if the Raspberry Pi could fill its shoes..."

"Leo Apotheker's disastrous tenure as HP's CEO revealed a dysfunctional company struggling for direction after a decade of missteps and scandals. Can his replacement, Meg Whitman, fix the tech giant?" As a consumer, I wish they simplified their product line-up. They have the engineering skills - I just have no idea what I'm supposed to buy when I visit their site. The choice for the ZenBook late last year instead of anything HP had to offer was elementary.

The BBC reviews the Raspberry Pi. "The device may inspire a new generation of computer programmers or it could leave children used to smartphones and tablet computers baffled and bewildered. A great experiment with the way we teach computing has begun and we can't be sure how it will end." Mine's coming the week of May 21.

"IKEA introduces UPPLEVA, a completely new range that integrates smart TV and sound system with furniture. UPPLEVA brings beauty and functionality to the living room, solving the problem of cable clutter and miss-match between TV and furniture." I'm throwing money at my screen but nothing is happening.

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.

"These drawings date from 1982 (thirty years ago). Alan Kay had just become the Chief Scientist at Atari and he asked me to work with him to continue the work I started at Encyclopedia Britannica on the idea of an Intelligent Encyclopedia. We came up with these scenarios of how the (future) encyclopedia might be used and commissioned Glenn Keane, a well-known Disney animator to render them. The captions also date from 1982." Pretty cool.

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.

"Little benownst to the world all this time, GoldenEye (N64) has a fully-functional ZX Spectrum 48x emulator built into it. By feeding it a proper Spectrum monitor program and calling menu 25 to load a snapshot, any Spectrum 48x program can be run. The emulator started life as a side project to see if Spectrum emulation was possible on N64 and was hooked into GE, the current game in development. It was supposed to be removed before release but was only made inaccessible and inoperable. All the registers, dependancies, and script required to run the emulator still reside in retail GoldenEye carts."

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.

"Some of my recent time has been devoted to making our boot media more Mac friendly, which has entailed rather a lot of rebooting. This would have been fine, if tedious, except that some number of boots would fall over with either a clearly impossible kernel panic or userspace segfaulting in places that made no sense. Something was clearly wrong. Crashes that shouldn't happen are generally an indication of memory corruption. The question is how that corruption is being triggered. Hunting that down wasn't terribly easy." Very interesting - and, unlike what the title suggest, not particularly related to the secure boot stuff.

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.

Raspberry Pi project leader Eben Upton talks about the state of Raspberry Pi, and tells us that yes -- finally -- they now have distributors in the U.S. and other countries instead trying to ship every unit from the U.K. Even better, instead of buying a batch of boards, selling them, and only then ordering another batch, the new distribution agreements mean they can keep a steady flow of orders coming in and going out.

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.
