  1. It's about time on U.S. Asked to Put Purchasing Power to Good Use · · Score: 5, Interesting
    With several other governments (Peru, Germany, Mexico, China) deciding that open source software makes better sense than closed, I've been wondering if/when the US would follow suit. I'm under no illusion that this letter will trigger an immediate change of OMB policies; Microsoft has too many lobbyists for that to happen overnight. However, it will serve to get the ball rolling.

    This is also an excellent time for the US-based portion of our community to follow up with our congressional representatives on this issue. Remember, both the House and the Senate place very little stock in email. If you want to get their attention, use either snail-mail or fax, as detailed above. Snail-mail only costs about $1, fax is even cheaper.

    1. Go here and get your ZIP+4 code.
    2. Go here and identify your Congressperson.
    3. When you click on the "Contact My Representative" button, you will be taken to a form. Ignore it. Instead, click on the link for your Representative and go to their homepage. Hopefully, they will have contact information someplace where you can find it. Copy it into your favorite word-processor.
    4. Go here and identify your Senators. Again, we hope that they make it easy to find their contact information.
    5. If you are thinking ahead, save three "empty" letters, addressed to each of the above. This will save time the next time you need to write.
    6. Use your word processor to write an essay explaining your position. Be verbose. Copy this into each of the three letters you prepared above.
    7. If you found any fax numbers (and your computer can print-to-fax!) send copies of your letter that way. Otherwise, print it out and send it by regular mail.
    Here's a suggested outline for the text of your letter (and, no, I'm not going to write it for you, staffers can spot a form letter a mile away):
    1. What problem would new OMB policies solve?
    2. How well would they solve the problem?
    3. What new problems would they add?
    4. What are the economic and social costs?
    5. Given the above, is it worth the cost?
  2. Re:Old timer comment... on Conceptual Models of a Program? · · Score: 3, Interesting

    I've said this before, but one of the best ideas that I ever encountered was that the length of variable names should be proportional to the size of their scope. So, one the one hand, this is OK:
    for (int i=0; i<size; ++i) { ... }
    (assuming that the "..." doesn't contain any braces), but function/method arguments should be longer, like this:
    int createWidget(string name, billOfMaterials parts) {...}
    and globally-visible items (like the class and function/method names above) get the longest names.

    Good things

    As you can see the MX-EVA3 can take care of some very high heat load. It is by far the best extreme cooling solution on the market today. I've used all sorts of cooling to get to the top and I was under the impression that my 220 pelt and chilled water cooler was bringing my chip to its limits. I was wrong.

    With the MX-EVA3 you can eliminate the use of pelts, extra power supplies and water. Now you use just one simple evaporator hook up.

    It also is pretty good for space. It fits under your case so all you're doing is adding about 9 inches to the height of your case. As far as the noise level it is very tolerable for any Xtreme Overclocker. This can only be written up as a good thing.

    Bad things

    I'll start with the instructions. They are very good for condensation proofing but that's about it. There are no instructions for adjusting the Digital Display as far as setting the boot temperature or setting what ever it is you can set with the 4 buttons on the Digital Display. This would be nice to know.

    They have no recommendation on moving your 4 AMD CPU tabs which in my opinion is a critical must.

    Mounting is a bit tough but if you take your time you can get it right. It's always a scary moment when it comes to risking frying your CPU. I'm sure the Intel 478 mounting may be a lot easier.

    "Alas, Maxwell's Demon is an impossible beast. [...] The essence of the refutation is that the Demon cannot see the molecules unless he uses a flashlight, and thus spends energy."

    The cooling chip uses externally supplied electricity to run. This powers the "flashlight", meaning that no violation of the Second Law need occur. The refridgerator in my kitchen does the same thing: It moved high-energy atoms from the coiled pipe inside to the grid of pipes in the back, by using electricity to move the atoms.

    I was a beta-tester for the HandEra 330, so my view of the price is a bit skewed, but it is definitely one *sweet* device. HandEra (the company) had done a lot of specialized stuff for Symbol long before the 330 came out, and they went the extra mile to make sure that the 330 would work with every CF card that Symbol makes.

  11. Re:OLTP for Linux on The Pros and Cons of Mainframe Linux · · Score: 2
    A difficulty in discussing this is that there's a breakdown of terminology. Unix invented the idea of seperate "fork" and "exec" primitives. All other OSs at that time only had a primitive which was very similar to the run-time "system" call.

    As I recall from the brief time that I did CICS programming, it was very similar to CGI programing, except that you weren't in a distinct process. Your program was running as something similar to a thread in a non-preemptive environment. Transactions were invoked and they ran uninterupted until they needed to perform I/O, say to the database. At that point, the thread was reassigned to another transaction's code. (I wanted to say that the thread was killed, but that's not accurate because it implies start-up/shut-down costs that just weren't there.) When the results of the database call were available, the transaction would be resurrected to process the data and transmit the results to the end-user. The whole process was designed to maximize throughput, but it required a coding style that was similar to writting CGI for Win-16. ;-)

  12. Re:Puzzling claim, somewhat buried on The Pros and Cons of Mainframe Linux · · Score: 2

    I scratched my head over this as well. SPARC processors *do* have the ability to switch between user and kernel contexts in a single instruction. This includes pushing and popping the registers on a special hardware "stack" (see this for more info). This might be what he was talking about.

  13. Re:OLTP for Linux on The Pros and Cons of Mainframe Linux · · Score: 2
    There are two UNIX/Linux solutions to that startup overhead problem. One is to build the transaction program into the network application (as in Apache/mod_perl/php). Note that this uses an interpreter to protect the network application from bugs in transaction programs, which is a major performance hit.

    I'm sure others will point this out too, but this just isn't true of mod_perl[...]

    What part isn't true? Perl compiles to an intermediate language, which is then interpreted. Yes, in mod-perl the application code is compiled the first time it's needed, but it isn't compiled into machine code, it's just turned into B-code, something that's more efficient to interpret that the original source. This is more efficient that CGI, where the compilation gets done over and over, but the B-code still gets interpreted with each request.

    How about Vonage DigitalVoice? They are selling a service for $39.99/month whereby you plug an ordinary analog phone into a "multimedia terminal adaptor", which in turn plugs into your cable/DSL modem (or a router plugged into same). Their service drops the call off at the local telco of the person you are calling, and gives you a phone number that people can use to call you.

    1) This reminds me of some '70s era arguments for and against the intellegence of dolphins. Dolphins have very large, complex brains. This is likely to process sonar images. The question is, does this complexity lead to intellegence, at least of a sort that can be understood by tool-using primates? It is still arguable that ocean-dwelling mammals are capable of detailed communication with each other, but we can't translate because we don't have referents. Also, several common definition of intellegence include things like tool-making. Creatures without hands are going to have a hard time qualifying, no matter how complex their society.

    2) Didn't you read the bit about long it took for cells to get organelles? Yes, once life comes around, it evolves in ways that increase the chances of eating and decrease the chances of being eaten. But that doesn't imply more complex. It's just as likely that evolution follows complex versions of "rock-paper-scissors". Birds evolved flight, but some (penguins, ostriches) have abandoned it. Are they more complex than their forebearers? Are snakes more complex because they evolved "beyond" limbs?

    Games magazine once had a puzzle consisting of a dozen photos along a very similar route; the goal was to put them into the proper order.
