Why even bother with Ethernet? Two FPGA's from any vender will talk with very little troubles. Do you need speed or distance?

Mike's response is the correct one: you use Baysian estimation to figure out what the probability that a certain bit was transmitted.

That website is about France and thus it is, um... self-explanatory. ;-))) Despite the fact that we call ourselves "European Union", there is no essential unification between our countries in this field. Each country has its own regulations, so no French labour time limit is applicable in, for example, Poland and vice versa. Here we have 40 hours/week + overtime, if necessary.

Well it's not for a lack of interest on this European's part, I can tell you. Attractive, slim, intelligent, single women are scarce in the UK. Maybe they don't have a problem with ugly fat stupid or married women in the USA? I guess being slightly plump is the least of these turn-offs.

Newly qualified, I was asked to design a simple Colpitts oscillator: 1 transistor, around 2MHz. I fished out my slide-rule, & prepared for a heavy afternoon's maths. My mentor stepped in, & said (in effect) "I know that's how they teach you in Uni, but it's not how we do it in the real world". His design logic went: 1. Supply voltage = 9V (that's what we've got available) 2. Transistor = BC109 (the stores are knee-deep in them) 3. Ic = 5mA (known by experience to work well) 4. Bias chain current = Ic/10 (ditto) 5. Vb = Vcc/3 (ditto) Now solve out the resistors, & give me a parts list. He signed the list, I took it to the stores & got the bits, & 20 minutes later, the oscillator was running. Theory vs Practice.

As a bonus, you may be able to offer the simple AES engine for the FPGA to use once programming is done." That's what I call simplistic and un-informed advice.

My income is essentially the same as it was five years ago (actually less) and I don't have health benefits now as I did then (I contract off and on now). ...though I do have more free time at this point so I suppose you could say this was a willing trade. However, I talk to lots of people who really aren't making more than they were five years ago and have less benefits. To some extent, I suppose this fall in incomes is inevitable given the global pressure on wages. But people in the US now certainly feel that things are less stable than they were a decade ago (less permanent jobs, more temporary or contract jobs). As far as other ways the US is declining: Well one of the big ones is that we have zero to slightly negative savings rates now. That's not sustainable longterm. Sure our real estate prices have gone up in the last few years, but that's mostly just paper gain (If you sell your house, you still need somewhere to live so if you buy another house you end up paying more anyway).

Some topics I would like to see addressed in the FAQ: Something about all the myriad file formats Xilinx's tools (ISE & others) use, e.g. what all these three-letter acronyms mean: "... but the XDL (or NCD) does __not__ contain bitstream info, it does hold the design info that is not mapped to the bitstream by bitgen later. NCD (that can be viewed as XDL after conversion) is used together with BFD (NeoCad Bitstream Format Database ?) file by bitgen for actual bitstream generation. there are some other files for each family, like GRD, etc I am able to view pretty much all of the files used by Xilinx tools, (NGC, NCD, etc) but..." (This was from Antti's recent message. And why not to add a whole topic about bitstream generation as well?) Other thing I (and many others) have needed: Basics about using Xilinx's DCM-stuff. Concrete examples in VHDL and Verilog. And what one writes to UCF-files? Yes, I know a lot's of this stuff can be found from their appnotes, if one has time to browse through them.

In some overseas McD restaurants they have laminated cards with pictures of the food items on them so that illiterates who only know English and not the local language can order unhealthy food. I did some work for a major equipment supplier of a certain large clown related restaurant chain- they have very high standards on how simple the devices have to be to operate. I think the alphas are the ones at the counter- the epsilon-minus ones can, at times, if present, be found in back.
