Very important to have an accurate reference to keep rf frequencies on target. Problem is that crystals drift over time. Very slightly, a few parts per million and you're screwed.
It had all been done before, but Rambus added the idea of doing it -- for RAM!
A protocol bus -- for RAM!
Terminated, controlled-impedance transmission lines -- for RAM!
Differential (actually threshold-based pseudo-differential) signaling -- for RAM!
Source synchronous clocking -- for RAM!
Delay-locked loops -- for RAM!
Bidirectional signalling using (current-mode drivers) -- for RAM!
When I worked there I patented the principle of linearity when it is used in time-domain simulations -- for RAM! (One of the less valuable but most crazy ideas.)
All that silliness aside, I don't think Rambus' 2.5% royalty justifies the price premium for RDRAM. However, the fancy wafer-scale packaging, the impossibility of production testing at 800Mbps in the year 2000 and the horrific heat generated by those 28-ohm current-mode drivers was enough to kill the technology.
I hate to quote the NRA, but guns are illegal in Mexico. And when guns are illegal only law breakers have guns. A lot of people on here are suggesting that Mexico legalize it. One could argue that "it" is guns.
This is more proof that Malaysia is not a real place. I mean look up some pictures of their subway or their big skyscrapers. Fake photoshopped renderings. Now think about where it is on a map. You can't. Because it isn't.
Performance reviews in companies are a sham to justify the HR VP's salary. If Bill Gates knew how to motivate productive then I would expect Microsoft's tens of thousands of employees to give OSX and Ubuntu a little stiffer competition. Most of Microsofts productive inovations come from acquiring startups. Startups do know how to motivate, by employing small teams of people who large stakes in the actual success of their project and using natural selection to weed out those who can't or won't succeed.
Another thing I wanted to mention is that IBM makes it's money on flip-chip packages. Flip-chip is technically superior to wire-bond, but does not allow you to stack which is desirable for mobile devices (regulator on DRAM on CPU is a typical in a baseband package for your phone). What IBM really needs to come up with is a superior, proprietary stackable package so they can start making money on mobile.
This article is a bit deceptive. IBM is not trying to create a package with 1000 high-end, high-power CPUs in it. Clearly, this would require 1000 times the thermal capacity in the cooling system, not to mention 40kW power supply to drive it and a pair of 40kA copper rails to bring all that current (at 1V) into and out of the package. This is not happening. The issue IBM is looking at is silicon defects. If you make a single MIPS processor per die, then you can get 10,000 of them on a wafer. If that wafer suffers 100 random defects, then you still have 9900 good die for 99% yield. However, if you try to make 64-core processors that are fashionable today then you only have 156 units on your wafer and the same 100 defects leave you with only 56 prime dice, for 36% yield which is shit. IBM's big idea seems to be to manufacture the multi-core processors which can be assembled from a multiplicity of known good die. They aim to build 64-core CPUs, by stacking tiny single-core CPUs, not the 64000-core CPUs that I pictured when reading this article.
Ok, Mr. Troll. You seem to have some strong feelings about this. But you're wrong about the PSN outage, or you have a strange definition of "hurt". During Q1'11, Sony lost $389 million. (The previous quarter, they had earned $72 million.) Since the beginning of the year, their stock has lost 40% of it's value. Sony's uber-powerful lawyers started this whole mess because they felt it was in their interest to sue a teenager. If they had prevailed, they stood to gain $100 from his sock drawer, but sadly, they did not. You're also wrong about Sony having more money and tech than me. Since 2008 I have earned more than SNE: http://www.google.com/finance?q=NYSE:SNE&fstype=ii

The company I work for outsources production to Singapore:
* Not due to a lack of technical expertise in Silicon Valley.
* Not due to differences in wages and other operating costs.
* Not due to a lack of capital equipment (though equipment is exported from California to Singapore for production).
The reason is export taxes. Singapore doesn't have them. And since a large fraction of customers are outside of the US, it only makes since to do production outside of the US. Even if Singapore has comparatively less experience and capital -- it won't for long.
Rambus was my first job out of college in 1999. I remember the shredding party well. I was like, why are we doing this? The old timers assured me it was perfectly normal. Anyway there was free beer, so that was nice. I haven't seen anything like it in my subsequent career. And free beer is all too rare.
I think it's because it takes so long to develop games for the latest generation of consoles, that it took several years for the PS3 and XBOX 360 to have any good titles. The Wii is unique in that the software was simpler and Wii Sports made it fun from day one. But PS3 was really a tough sell. When it came out all you could play was this silly truck racing game that wasn't fun compared to PS2 games and didn't even look that cool. We're just starting to see some good games for PS3 in the last year or two. For the next generation of consoles they should try to release some kind of developer kit years in advance.
My Android phone transcribes search terms from voice input. I wonder if there's a way to use Google's voice transcription servers. No idea how, but it seems like Google has already done the hard work.
I'm not so sure about that 62,000 miles figure. That's more than the circumferance of the earth.

Probably nothing. There have been 3d displays for years for both TV and computers where you had to wear some kind of special glasses. Every now and then game and CAD complanies take a stab at developping for them, and it's always a huge failure. Sega had a game where you shot at missiles in 3d. Capcom made a raster arcarde game where you looked through some glasses to pilot a tank in 3d. Those ViewMaster slide viewers they sell at theme parks are an older, non-electronic example.
It's all crap and I'll tell you why.
Adding depth perception is a cool gee-wiz trick, but ViewMaster's never encroached on photographs or 3D games on 2D games because it really doesn't do a lot for the experience. You move your head to the side to get a better view around the corner of your 3d object, but you're still looking at the same image, it just bends along with your head moving. It's a nausiating effect. And it's just a 2d image with a perception of depth. Don't think that you'll be manipulating objects in any meaningful 3D way. You can't put one object behind another. No way. All you can do is map your 2d image over a depth field.
Sorry this comment is a little disjointed. My main point is, if their were serious CAD, entertainment or gaming applications for 3D they would have appeared long ago, and don't invest in this glasses-free 3D technology because it's a warmed over bad idea.

I'm going back to Linux.
And good for Nintendo. You can't legitimize every crank who comes calling. Though slashdot seems willing to do so.

Why isn't this built in to mobile phones? You'd reach a lot more people quicker through SMS than TV.
Don't forget to hate Lion with its stupid Launchpad and lack of Spaces/Expose like they used to work.

+1 for hating WNDR-3700. Good on paper, but I have to restart it at least once a day and it runs hot.
