Comment Watering the foundation of our houses! (Score 2) 318

Talk about a waste of water: parts of north Texas (and many other areas obviously), have clay soil which moves in crazy ways if allowed to dry out too much. This moves you house in crazy ways, causing cracks inside and out. The solution? We're encouraged to water our foundations. Huge amounts of water go to this, which results in our lake levels getting low, which puts us into water restrictions where we can't water the lawn.

Better solutions would be (1) build the foundations to withstand the soil moving, (2) and/or use a different method to keep the soil stable. I'm skipping (3) move elsewhere because DFW is not going to sprout legs and go take over Oklahoma. Unfortunately (2) likely suffers the same problem as the current solution of watering the foundation with soaker hoses: it's basically impossible to do it evenly... so you end up with overmoist areas, and other areas that still move some.

the embedded space has used lots of PPC for years. Notice it stated SoC?

Exactly right. We're designing a high-end router right now with 40 Gbps ports and the management CPUs are PPC based - just like all the other equipment we've designed (and all the other vendors too) for the past 15 years. In this case, one of the CPU's even runs Linux.

Comment Funny responses (Score 3, Interesting) 433

It's funny reading all the responses saying "It's obvious"... and then each response gives a different cause.

If I knew then what I know now, I would probably not have gone into electrical engineering out of fear of offshoring. Thus far it hasn't completed killed engineering in the USA, but it has certainly made a big dent. But I don't know that the majority of young engineers know to even fear that...

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?

Comment Re:more jobs for me (Score 1) 188

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.
