    Promoting your new beliefs when you've recently changed is more a property of 20-year-olds than it is of atheists. Since more people have a religious upbringing than not, the population of noisy 20-year-old atheists is going to be quite apparent. On the other hand, recent young converts to pushy fundamentalism are a pain, too. The difference is, if you agree with the atheist he'll go away and stop bothering you, the religious guy wants to hold your hand and have a prayer session.

    Identifying Hitler as conservative because of his facade of promoting Christianity is misleading at best. There's more to conservatism than religious support and stuffy moralism. In particular, no person who wants big government and high taxes can be a conservative, despite what that person claims.

    About a year ago I worked with a loudspeaker box design program. I found some peculiarities in the results, but at first I wasn't very concerned. Eventually I found I could get different results without changing the inputs. I became concerned and examined the code. The parts generating the display I didn't understand, the parts getting the input I didn't look at. I studied the formulae that determined the frequency response, and part of it was just plain WRONG.

    Keyboard focus switching is a supplement to, not a replacement for, focus-follows-mouse. Alt-tabbing around becomes tedious when the window I want isn't in the 1st 2 or 3 windows on the list, or it's hard to determine which window is being selected.

  16. Re:3D chips on Graphene Transistors 10x Faster Than Silicon · · Score: 1

    Although 3D chips would be advantageous, they would not be as big a gain as it first appears. With devices and conductive layers, the electrically used portion of modern ICs is about 30 times as deep as the minimum feature size. (I've been out of the field for a decade, corrections appreciated.) That includes a few layers for the active devices and maybe 6 layers for conductors. So for a 20 nanometer process, 10,000 layers of which 1,000 are active device layers, the first nominal expectation is 1,000 times the processing power. Hovever, much of the area of inner layers is going to be vias (wires between layers), so the gain won't be 1000X. It would make a chip 1000 x 30 x 20e-9 = 600e-6 m thick. OK, that's less than what I first thought, it's about how thick chips are now. Two problems occur to me. The first is power dissipation, which others have mentioned. To some extent, this can be worked around by making designs that have low leakage, static (CMOS) design, slower clocks, and circuitry most of which is inactive at any given time. All of that decreases performance. The second problem is yield. Even when all other problems are solved, big chips have yields in the 50% range. Double the number of layers and you will cut the yield to 25%. At 100 layers (10 layers for active devices) the yield will be 0.1%. At 10,000 layers, not one working device could be made in the age of the universe.

  17. Re:Transistor count on Intel Details Upcoming Gulftown Six-Core Processor · · Score: 1

    There are some sped-up versions, although nowhere near 3.2 GHz. (For instance, a 25 MHz Z80). There isn't any point to having a 3.2 GHz Z80 if the Z80 architechure is preserved. Z80 instructions required 4 to 17 cycles to execute (IIRC) and multiple memory cycles whenever external data was accessed.

    There are many, many things that could be done to improve the Z80 with modern technology and most would break compatibility in some manner. For instance, a great speedup could be made by putting the entire 64k memory space on die, but that would break anything that required memory-mapped external access. Pipelining and wider memory could make all instuctions single cycle, provided the memory access was multiport. A multiply instruction would be nice.

    Really, there are better uses of technolgy available than investing $1M or so on a 3.2 GHz Z80.

    Nonetheless, I understand the feeling. I'd like to see one, too.

    You mention "an entire C64 or Apple II on one chip". The SOC philosophy is a good one, and for a long time chips have been available with many of the I/O functions on-chip. However, I doubt that there's anything that completely duplicates a C64 or Apple II. What could be done is to implement an 8 bit computer, inclding memory, on an FPGA. Then you'd just have to add power supply, level-shifters for RS-232 &c, power supply, disk drive, case... Fun games. Really, an emulator running on a modern computer would be less work.

    But, if you match the strength of the brittle material to the ultimate strength of the deformable material, you have met your design criterion.

    That analysis fails 2 ways. First, it fails to account for shock loading. A transient load that is equivalent to the ultimate strength of steel could deform the steel, absorbing part of the shock, before the actual failure predicted by the ultimate strength took place. Second is the problem of stress concentration at flaws. The deformable material may flow in a way that reduces stress at the flaw, but a brittle material is likely to see the flaw expand, making things explosively worse.

    Brittle materials need a greater safety margin or some form of design that works around their problem, such as embedding fibers of the brittle material in a plastic matrix.
