Think Atom processors running Android, or High-performance computing applications. Neither of these require a huge external ecosystem, but if you get a 30-40% boost in some workload, they are worth it. It's my understanding that small-cache Atoms benefit from this more than huge Xeons.

My Nissan Frontier and Toyota Sienna were both manufactured in the US, though it's more likely the vehicles themselves are tailored to the NA market in the first place. I've worked at companies that do a fair amount of domestic electronics manufacturing, and it is really difficult to get a big, complex design even 95% defect free when human error is involved. Designing products and packaging that can survive shipping and various installation mistakes (even domestic, first class shipping) seems to be a big portion of the nightmare. Unless you have a very high margin or volumes, RMA costs can completely erode your profit. And often by the time you've solved all of the problems, the product is next to obsolete :P.

In my opinion, it is designed pimarily so that Intel's embedded processors run Android well in the short term. Atom architecture in particular benefits in that some pointer offset calculations are faster when done in 32-bit vs 64-bit.

An XFI-SFI interconnect runs up to 10.3 Gbps on a single serial link. It is double-pumped (bit on each end of the clock) so the clock rate is half that. This is the connection that links a 10Gbps phy to the transceiver module. You do have to keep the interconnects pretty short though.

Also, note how this is not a single serial 50 Gbps link - it's 4 parallel 12.5 Gbps links. You can run light in parallel with no interference, the trick is to make sure that each independent channel uses a different wavelength instead. So, they are doing it in parallel. Some 100 Gbps ethernet standards use 10 parallel 10Gbps lasers running at different wavelengths, but they are amazingly expensive because of this.

PS3 Hacked? 296

Posted by Soulskill
from the another-one-bites-the-dust dept.
Several readers have sent word that George Hotz (a.k.a. geohot), the hacker best known for unlocking Apple's iPhone, says he has now hacked the PlayStation 3. From his blog post: "I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1. I've also dumped the NAND without removing it or a modchip. 3 years, 2 months, 11 days...that's a pretty secure system. ... As far as the exploit goes, I'm not revealing it yet. The theory isn't really patchable, but they can make implementations much harder. Also, for obvious reasons I can't post dumps. I'm hoping to find the decryption keys and post them, but they may be embedded in hardware. Hopefully keys are setup like the iPhone's KBAG."

Well, the Native Development Kit (NDK) lets you build native code. There is a regular C/Unix environment underneath. If you look at a project like the Android Scripting Environment, they've managed to make Python, Ruby and Lua work on the phone, packaged as an .apk and not requiring root access. http://code.google.com/p/android-scripting/

You can compile pretty much anything for the phone, without needing root/Debian, though its not always as simple as 'apt-get install', for sure.

One way is to use the Native Development Kit, which lets you run regular C code on the phone. Here's a post explaining how to bind to bluez: http://blog.blackwhale.at/2009/08/android-bluetooth-on-steroids-with-the-ndk-and-bluez/

The other way is to use the existing android bluetooth API: http://code.google.com/p/android-bluetooth/

What that developer has done is use java reflection to wrap the existing (just not documented) android.bluetooth class API. I've been using it to communicate with an OBD-II adapter with some success (thought the dynamic port discovery API doesn't work entirely.)

For tethering, Wifi Tether works pretty well, since it doesn't even require the laptop to support bluetooth. It makes your phone a portable ad-hoc access point. Does require root access, for which there are some one-click solutions out there.

This system will self-destruct in five minutes.

Working...
