Comment Re:Intruiged (Score 1) 274

We never undock our Transformer that we've had since mid-summer - so we use it more like a netbook. But it really opens your eyes to how certain use cases are really improved used touch screen. Yes, you can get by with a mouse, but there are many things which are really much more efficient with touch. After extended use, my wife and I bought try to touch the screen on non-touch laptops - it is so much more natural than a mouse.

Comment MOD parent up (Score 1) 35

Parent is exactly right - there is nothing fishy about law firms immediately putting out press releases about pending "investigations" when a public company gets an offer to be bought. Just go research any notable purchase over the past few years. It's really sad.

Comment Re:FPGA compatibility? (Score 1) 403

I think that if there's any likelihood of Bitcoin becoming significant, there's also going to be an increasing likelihood of someone dividing the problem space in such a way that it's addressable with appropriately-designed FPGAs and thereby killing that likelihood of significance. Right now it's unlikely to be worth anyone's time & money (unless it's being examined in classes), but if there are significant $ there someone's going to be pursuing them.

There is no way to know without doing the FPGA design, at least at a high level. What you might make up for in one area, you might lose in another. The fact that the AMD's run at such a high clock rate with so many ALU's makes me doubt it would be worth it - but again, there is no way to know for sure without doing considerable work. Just going on number of ALU's (which is not really a proper way to compare, but is the only thing we for this discussion), only the latest HUGE and really expensive Virtex 7 parts have more DSP's.

Comment Re:Cable Card (Score 2) 119

An effective Linux DVR is possible. I know it is not ideal, but you can use an HD-PVR in Linux to capture (in 1080i) the output of any device that provides component output. That's what many MythTV users do... rent the cable company box and just capture the output. Like I said, not ideal, but it is possible, and many are doing it.

I never understood why management isn't in the basement and IT infrastructure on the top floor. It makes a hell of a lot more sense.

Because management gets to decide what goes in the basement. Why would they waste a perfectly good view by giving it to the servers and routers?

FPGA programming (or rather desiging for an FPGA, implementing algorithms) is not so much about EE as it is about CS.

Wrong. It has little to do with CS - and in fact, if you approach it that way, you'll make code that the synthesis tools can't handle efficiently. You'll end up with many levels of logic and won't meet your timing requirements. FPGA "programming" is about describing digital circuits in an HDL.

s/some vendors/most vendors/

Telecom and datacomm equipment have long used FPGAs at key points in their systems for one or more of the following reasons:

* off-the-shelf silicon sometimes costs to much

* off-the-shelf silicon is missing something that is important to you (maybe an interface type, or a key feature)

* off-the-shelf silicon doesn't have the density

* ASIC's cost a lot to develop, and prices have been going up (while each year, FPGA prices go down). If you don't have pretty high volume, each year it has gotten harder and harder to justify.

A number of HDTV's had Xilinx Spartan FPGA's in them... I'm guessing that some still do.

How does one go about "sucking profits"? What does that even mean? If you're going to advocate telling people how, with whom, and when they are allowed to buy or sell items with other willing individuals, you should at least have the common courtesy to clearly explain why such voluntary trades should not be permitted to occur.

I'm pretty libertarian, but I agree these should be stopped.

Me too (on both accounts)

As the other poster said, it gives real estate closer to the market servers an advantage, I'm not quite clear how it works, but it is evident that it does because people are doing it. I assume they can recognize short term patterns and jump in ahead of anyone else who might try to take advantage of them.

Trading is something where we want to have as level a playing field as possible. It's also something specifically designed to serve humans. The speed of your computer and connection shouldn't give you an advantage. It keeps our market freer.

This discussion is more accurate than most of you probably realize... I work for a router equipment vendor. Guess what the main market for ultra-low latency routers is? That's right - they have realized on Wall street that a router with lower latency means a higher chance of getting your trade in before your competitors. If your router has a latency of 500 nsec while your competitors all have 600 nsec routers, you have the advantage. At least until someone ponies up and buys one that is lower than yours.

Successful trades shouldn't have to be measured in nanoseconds.

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
