Big news from ARM over the past few days. The processor architecture, once strictly an embedded affair for low-power devices, is going big. Not only has ARM announced it's going 64bit, HP has announced it's going to build servers with ARM processors. It seems all the pieces are now in place for ARM.

According to physorg.com (via popsci), the Cray Inc. XT5-HE supercomputer (Jaguar) is getting updated. The Department of Energy's Jaguar computer will be renamed Titan. This reported $97 million upgrade will be using AMD CPUs and NVIDIA Tesla GPUs and is claimed to "be at least twice as fast and three times as energy efficient as today's fastest supercomputer, which is located in Japan." Good news for gamers.

Remember the Raspberry Pi ARM board we talked about last week? Well, while running Quake III is all fine and dandy and illustrates the board is capable of something, it didn't really tell me anything since I'd guess few people are going to use such a board for gaming. So, I was pleasantly surprised to see that the Raspberry Pi team posted another demo today - running 1080p video for eight hours straight. The chip was still cool to the touch. And just to reiterate: $25.

We all know platforms like the Beagleboard, which are cheap hardware platforms which can be used in all sorts of projects. A new entry into this market is Raspberry Pi, a British ARM board which is slated to be released in the fourth quarter of this year. For a mere $25, you'll have a fully-configured ARM-based 1080p-capable mini-motherboard. The device is still in development, and only a few days ago, the alpha version of the board was demonstrated running Quake III.

Major bombshell, and sorry, but this certainly requires a breaking tag as well: HP has announced it is discontinuing operations for webOS devices - effective immediately. Just like that... The TouchPad and Pre 3 are dead. Eh. Raise your hands if this brings back those painful memories of that infamous 'Focus Shift'. In addition, the company also announced its intention to sell its personal computer business.

Researchers at the Virginia Commonwleth University have come up with . . . a circuit that requires such little power all it needs is the ambient energy in an environment to run. In other words, it can run without need of a power lead or battery, relying instead on some energy constant in the environment in which it functions e.g. the human body. In order to create something that can run on such low, ambient energy, you need to use electronics that require next to no power to function. So instead of the typical charge-based electronic switches used today, the researchers turned to spin transport electronics, more commonly known as spintronics.

And yes, another item, right away. I'm on the hunt for a mini-ITX motherboard for use in a living room HTPC, and considering there's so much choice out there, I'm a little confused. Then I realised I have you people to help me out, and, well, one thing led to another.

"Keen observers may recall that Asus's debut of the Padfone back at Computex in May was accompanied by another, albeit less-trumpeted announcement. Specifically, the company promised a $199 netbook computer - the MeeGo-based Eee PC X101 - and this week that device took several steps closer to reality."

"Back in the 80s, the Commodore C-64 had an intelligent floppy drive, the 1541, i.e. an external unit that had its own CPU and everything. The C-64 would send commands to the drive which in turn would then execute them on its own, reading files, and such, then send the data to the C-64, all over a propriatory serial cable. The manual for the 1541 mentioned, besides the commands for reading and writing files, that one would read and write to its internal memory space. Even more exciting was that one could download 6502 code into the drive's memory and have it executed there. This got me hooked and I wanted to play with that - execute code on the drive. Of course, there was no documention on what code could be executed there, and which functions it could use." Very interesting. I'm most interested in how he describes others taking his work, and making it better. This would be impossible today, thanks to Microsoft, Apple, and other patent trolls.

Both IDC and Gartner have released their PC shipment analyses again, and as it turns out, worldwide PC sales are on the rise. Gartner: "Worldwide PC shipments surpassed 85.2 million units in the second quarter of 2011, a 2.3 percent increase from the same period last year, according to preliminary results by Gartner, Inc. These results are below Gartner's earlier projection for 6.7 percent growth." IDC, too: "Worldwide PC shipments increased 2.6% in the second quarter of 2011 (2Q11), according to the IDC Worldwide Quarterly PC Tracker." From large to small, the world's largest PC manufacturers are HP, Dell, Lenovo, Acer, ASUS, and Toshiba. Lenovo demonstrated the largest growth worldwide (+22% compared to Q2 2010). Apple did quite well in the US, but doesn't register on the worldwide scale.

HP's CEO Leo Aptheker is currently on stage at D9, answering questions from the audience. The thing hasn't concluded yet, but I think this one warrants its own item: Apotheker has revealed that HP is also licensing webOS to other hardware makers. "It's a great OS - why wouldn't we want to offer it to other companies? Why wouldn't they want to use webOS? Appliance makers could use it to connect up normal home devices. We'd like to make webOS available to these people - enterprises, SMBs, etc. Yes, webOS will be more than just a system that runs inside an HP product." When asked more directly if, for instance, HTC could build webOS phones, Apotheker answered: "We'd certainly have that conversation."

I'm going to become short of suitable title suffixes pretty shortly... Anyhow, I have also reviewed interrupts on the MOS 6502 for the sake of extreme completeness, bust most importantly have tried to address some very incomplete and misleading statements of the interrupt handling model about pop-up threads and service-providing processes in a rather extensive way, see this post.

HP scientists have made a small breakthrough in the development of a next-generation memory technology called memristors, which some see as a potential replacement for today's widely used flash and DRAM technologies. In a paper to be published Monday in the journal "Nanotechnology," scientists report that they have mapped out the basic chemistry and structure of what happens inside a memristor during its electrical operation.

Cheap routers sometimes lack a bit in functionality. Maybe you wish yours did VPN, had a guest network for relatives passing by, or supported IPv6. In most case, the hardware supports it, and all it takes to get these options is to install an alternative third-party firmware. Such firmwares also are frequently more reliable and faster than vendor-provided ones. So why not give them a try?
