    If you're looking for non top-40 stuff, eMusic is a good deal less expensive and has been DRM free since it started. I've not used iTMS since they stopped jHymn from working - fortunately, eMusic has *completely* filled the gap.

    The only disadvantage of eMusic is you pay a monthly fee rather than a fee per track so it's not for everyone, but you only have to buy one album's worth per month for it to work out cheaper.

    So you are less dead if you happen to be killed in a car that gets run over by a plane, than in the aircraft itself?

    A fatal accident is a fatal accident. It was absolutely counted in the airline accident statistics as a fatal accident. It wasn't caused by the design of the airfield - it was caused mostly by an error by the flight crew (as was the earlier runway overrun accident). It's so wrong to say SouthWest has had no fatal accidents that it isn't even wrong.

    Here is the *official* NTSB report for the most recent accident - notice that if you go to the NTSB website, and select injury severity 'fatal' and airline 'SouthWest', it comes up. The NTSB *definitely* count it as a fatal airline accident. Note - Injuries: 1 Fatal, 12 Minor.

    NTSB Identification: DCA06MA009.
    The docket is stored in the Docket Management System (DMS). Please contact Records Management Division
    Scheduled 14 CFR Part 121: Air Carrier operation of SOUTHWEST AIRLINES CO
    Accident occurred Thursday, December 08, 2005 in Chicago, IL
    Aircraft: Boeing 737-700, registration: N471WN
    Injuries: 1 Fatal, 12 Minor, 103 Uninjured.

    This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed.

    A Southwest Airline B737-700, flight number 1248, slid off the runway at Chicago Midway Airport. The flight was from BWI to Midway. There was snow at the time of the accident. The flight was delayed from leaving BWI due to weather and held for 35 minutes before landing at Midway. Upon landing at Midway the airplane slid of the runway and went through a barrier fence and onto a roadway. There were 98 passengers onboard and 5 crew members on board. An emergency evacuation was done and no injuries have been reported. There are prelim reports of one ground fatality and 12 other ground injuries.


    A probable cause has not yet been issued by the NTSB, but there were some reported procedural deviations by the crew which are likely to be listed as a factor when the final probable cause is reported.

    There are plenty of embedded microprocessors around that do NOT expect DDR2 speeds. Many digital circuits simply don't need a 2GHz space heater and run just fine with a 2MHz Z80 or equivalent (indeed, the Z80 is still manufactured and popular in its 'classic' 40 pin DIL form. I have one on my work table that was manufactured less than 6 months ago). Many many products use chips of this sort of class.

    Just because there's a clamour for ever faster (and hotter) chips in PCs and servers, it does not follow that the same is true of an embedded computer. If a 4MHz processor works for a particular application, there is absolutely no benefit in using something that 'expects DDR2'. Normal 70ns static RAM and flash chips are sold by the millions because they are cheap, electronically simple to interface, and low speed circuits are much cheaper and easier to lay out on a PCB. You don't need DDR2 on a weather station embedded computer or washing machine.

    Many microcontrollers like the Atmega can interface with external memory (even though they have some internal flash and RAM).

With a T1 or similar line you'll get a service level agreement for a guaranteed rapid fix.

  20. Re:The Birthplace of the Megahertz wars on 25th Anniversary of the Sinclair ZX Spectrum · · Score: 1

    _Nothing_ in Rightpondia used the S-100 bus. All the Z80 machines available here had a memory mapped framebuffer - the Spectrum had a memory mapped frame buffer, as did the Amstrad CPC lineup. Indeed I don't think there was any British computer that did it the way you say.

    No, even back then, SRAM used much less power. Static RAM constructs each memory cell out of six complimentary MOSFET transistors (and did so back then; I have some Toshiba static RAM of that vintage and that's exactly how it works, and it has a quiescent current that's a fraction of DRAM of the same vintage).

    Each DRAM memory cell consists of a capacitor and transistor. Each SRAM cell consists of six complimentary MOSFETs. This is why SRAM is more expensive - six transistors per cell rather than one transistor and one capacitor. SRAM is also generally direct addressed, and therefore has more pins on the package which adds to the expense (but removes the need for some of the glue logic between the CPU and the memory). These six transistors use vastly less power because:

    - you don't need to charge the capacitor
    - you don't need to continuously keep recharging that capcitor (i.e. DRAM refresh)
    - complimentary MOSFETs (CMOS) *only* uses power when changing state (due to 'crowbaring' - in a complimentary NMOS/PMOS pair, both transistors will briefly be conducting when the state of the gate is changing). When just holding a memory value, the current usage is utterly trivial - leakage currents measured in picoamps. This is why even in the early 80s, static RAM was used for battery backed nonvolatile memory: the quiescent current of the device was miniscule, which couldn't be said for DRAM. Even in a running system, the majority of RAM is just keeping state.

    Many dynamic RAMs were also complex to power too - the popular 4116 DRAM required no less than 4 power rails (+5v, -5v, 12v and GND) - which meant the computer needed some kind of internal switch mode power supply to supply these voltages. Static RAM of early 80s vintage were all single 5 volt supply. This also added to the current draw of DRAM of that period, when you consider the losses in the required power supply.

    The Z80 was no more of a kludge than the 6502. It was merely binary compatible with the 8080, the design was a clean sheet electronically (and eliminated many of the problems with the 8080, including the complex power supply required for the 8080, and providing built in dynamic RAM refresh so computers could be constructed inexpensively using DRAM). The optimizations taken with the Z80 were merely different to the 6502 - the Z80 traded off operations per clock for a comprehensive instruction set to keep code small, and the 6502 traded off complexity for being able to do lots of small instructions quickly. The result was both chips actually executed at around the same speed (the 6502 was always rated about no more than 1/3rd of the clock speed of the equivalent Z80), except the Z80 had a definite advantage when it came to code size. It also had a distinct advantage when making a computer designed around the Z80, because the Z80 had built in DRAM refresh, as well as a separate 16 bit I/O space which meant you could use the entire memory map for memory. (It also made bank switching much easier, too, at an electronic level, and I/O glue logic can be much simpler with a separate I/O space since address decoding can be simplified. It's no coincidence that Z80 based systems tended to be considerably less expensive too, certainly on this side of the pond).

    You can't say the Z80 was inferior because some designers just substituted an 8080 for the Z80, without using the features of the chip such as built in DRAM refresh. Systems actually designed around the Z80 didn't have any of the drawbacks or odd screen memory access issues of which you speak.
