"RISC OS Open are very pleased to announce the official release of RISC OS for the Raspberry Pi, 'RISC OS Pi'. This is a watershed moment for RISC OS and represents the culmination of many months of hard work from a whole community of developers, testers and other contributors. It also means the Raspberry Pi can now boast support for the quick, compact, original ARM-based operating system." This is absolutely fantastic news. I'm going to try this on my Pi later this week.

Nope.
That would be the PandaBoard ES, which has a dual core Cortex-A9 at 1.2 GHz. (There is also a 1.0 GHz PandaBoard that the ES effectively replaced.) However, RISC OS doesn't support multiprocessor systems, so one core stays idle. I suspect the PandaBoard also has the fastest floating point, as the TI OMAP4's version of the Cortex-A9 core has the VFPv3 unit included.
Also, the BeagleBoard xM (1 GHz Cortex-A8) and BeagleBoard (600 MHz Cortex-A8) are both faster than the Raspberry Pi's older 700 MHz ARM1176 for integer work. However, the Raspberry Pi is faster for floating point, as it seems that RISC OS has standardized on using VFP for floating point, instead of NEON (ARM backpedaled on the whole "deprecating VFP" thing that they tried with Cortex-A8, now it's just that the vector VFP instructions are deprecated, and NEON is used for those), and the Cortex-A8 uses a badly crippled VFP unit.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.

The day has finally come: Google has started shipping Google Glass to the lucky few early adopters. Now that it's shipping, Google has also unveiled a lot more about the API and the specifications of the device itself. While the company had already given out substantial details at earlier occasions, there are still a few surprises here.

Almost exactly three years ago, I wrote about why OSNews was no longer OSNews: the alternative operating system scene had died, and OSNews, too, had to go with the times and move towards reporting on a new wave of operating systems - mobile, and all the repercussions that the explosion of smartphones and tablets have caused. Still, I was wondering something today: why aren't we seeing alternative operating systems on mobile?More Features »

I'm going to try it out right now. Is the Raspberry Pi now the fastest computer that can run RISC OS natively?
