Quake 3 For Android 137

An anonymous reader writes "Over the last two months I ported Quake 3 to Android as a hobby project. It only took a few days to get the game working. More time was spent on tweaking the game experience. Right now the game runs at 25fps on a Motorola Milestone/Droid. 'Normally when you compile C/C++ code using the Android NDK, the compiler targets a generic ARMv5 CPU which uses software floating-point. Without any optimizations and audio Quake 3 runs at 22fps. Since Quake 3 uses a lot of floating-point calculations, I tried a better C-compiler (GCC 4.4.0 from Android GIT) which supports modern CPUs and Neon SIMD instructions. Quake 3 optimized for Cortex-A8 with Neon is about 15% faster without audio and 35% with audio compared to the generic ARMv5 build. Most likely the performance improvement compared to the ARMv5 build is not that big because the system libraries of the Milestone have been compiled with FPU support, so sin/cos/log/.. take advantage of the FPU.''

Bill Gates Puts Classic Feynman Lectures Online 338

theodp writes "Okay Tux fans, let's see how badly you want to see Feynman's Messenger Lectures on Physics. Bill Gates has the goods over at Microsoft Research's Project Tuva site. Also, CNET's Ina Fried has an interesting interview with Gates. He goes into why he spent his own money to make a series of classic physics lectures available free on the Web, talks about the possibility of Project Natal bringing gesture recognition to Windows, gives his thoughts on Google's Chrome OS, and discusses plans to patent 'cows that don't fart.' The last is a joke. I think."

Kurzweil on the Future 300

dwrugh writes "With these new tools, [Kurzweil] says, by the 2020s we'll be adding computers to our brains and building machines as smart as ourselves. This serene confidence is not shared by neuroscientists like Vilayanur S. Ramachandran, who discussed future brains with Dr. Kurzweil at the festival. It might be possible to create a thinking, empathetic machine, Dr. Ramachandran said, but it might prove too difficult to reverse-engineer the brain's circuitry because it evolved so haphazardly. 'My colleague Francis Crick used to say that God is a hacker, not an engineer,' Dr. Ramachandran said. 'You can do reverse engineering, but you can't do reverse hacking.'"

Bill Gates's Last Speech 389

from the complete-with-ballmer-bot dept.

Ian Lamont writes "Bill Gates, in an address to the TechEd Developers conference, talked about Microsoft's plans for hosted services, and revealed that the company is planning data centers on 'a scale that we haven't thought of before' that will apparently enable the company to offer all of its server-based products over the Internet. The talk did not include details in terms of capacity or scale. This was Gates's final publicly scheduled speech as a full-time Microsoft employee, and he acknowledged that Microsoft's success is 'due to our relationship with developers.' On July 1, he will start spending most of his time at The Bill and Melinda Gates Foundation." After that date he will be devoting his "20% time" to Microsoft.

Windows 7 Multitouch Demonstration 329

Starturtle writes "Bill Gates and Steve Ballmer have shown a small snippet of the upcoming Windows 7 at Walt Mossberg's D: All Things Digital conference. It seems like the Windows team have switched their focus for inspiration from Mac OS X to the iPhone OS. Multitouch is the biggest addition, and will appear system-wide, usable anywhere. The most interesting part of the touch UI is not the eye candy, it's the Task Bar, which seems to have morphed into a pie menu."
