  1. Writable stuff in bank notes? No way. on Europe Adding RFID Tags to Euro Currency · · Score: 2

    The article is extrapolating WAY too far from what they know.

    Now people are ink-jetting integrated circuits onto paper, it's interesting to try that for this application.

    Already reasonably useful would be a way to easily identify individual bills once they are back at the bank.

    They started putting barcodes on the Dutch notes a while back. This would suffice for that purpose. I'm not sure wether the Euros will have those.

    I'm not sure what an RF ID would help. Would every shop suddenly have an RFID tag reader? No.

    They also speculate something about recording transactions. Well, it's going to be tricky to hide those batteries and GPS reciever in the banknote....

    Take a kitchen "lighter". One that produces sparks once you press it.

    Take a copper wire and make it into two loops. Attach one end to the outside, and allow the other end to come close to the center "zapper". Make sure that the sparks now go through the loop.

    This is for sure enough to make a CPU skip a cylcle, but may not be enough to physically damage things too much. Exercise for the reader: Find a way to produce bigger sparks....

  15. Re:WTC impact on Boeing to Develop a Fuel Cell Powered Airplane · · Score: 1

    By your argument, I could be an olympic athlete in training, and the day before the big event, I could either eat a 2000 calorie salad for dinner, or I could eat 2000 calories of Snicker's bars.

    If you run a marathon, eating 2000 calories of snickers is a good thing, about half an hour before the start of the run: Snickers have a mix of glucose (active 15-30 minutes after ingestion), sacharose (active 20-60 minutes after ingestion) and starch (active 45 to 120 minutes after ingestion). And then there are fats which you end up burning a few of near the end of a marathon too. I'm not sure wether fats are "ready for burning" if you didn't eat them weeks before. So the calories contained in the fat in the snickers may be wasted on the marathon runner.

    Salad is "good" because it contains fibers and stuff. The day before the "big event" that's no longer going to help you. 2000 calories of Salad is "bad" because a pure vegetable salad is almost calorie free. Thus you'd have to overeat A LOT before you get 2000 calories.

    If a hydrogen-burning airplane would've hit the WTC, there would have been a much more fierce explosion at impact. And a Humoungous fireball for the one or two minutes after that. And no more WTC after 3 minutes. (You get an explosion limited by the amount of oxygen that can be provided...)

    I think that the impact blast would've been powerful enough to collapse the buildings like now happened after 50-80 minutes.

    If the fuel cells would run on say methane, similar things happen. Methane burns cooler. Less violent explosions. But still orders of magnitude more violent than airplane fuel.

    If you have a wooden bar, and hit it with a hammer, trying to break it, there is a certain amount of energy required before it will break. If you slowly push it using a jack, you will find that you need almost the same amount of energy to break it.

    Breaking the WTC took a certain amount of energy. The airplanes contained that amount of energy, not in their kinetic energy, but combined with their fuel-supply they HAVE the required energy to "break" the WTC in two. Complete destruction was then due to the energy contained in "20 stories of WTC falling down".

    An airplane fuelled up for a 10 hour flight simply has enough energy to bring down the WTC.

  18. Re:Sorry to pour cold water over the idea... on Upping The Softmodem Code Bounty -- To $20,000 · · Score: 1

    Depending on the quality of modem you are trying to do, CPU horsepower requirements are huge. A bare-bones V.34 implementation requires around 40 MHz of a Pentium-class CPU, while a robust bells-and-whistles version needs something like 90-95 MHz. Don't expect a 486 to handle the load.

    So? You can't run a HSP modem in a 486? So, don't.

    HSP makes sense. Suppose you have $150 to buy a CPU plus modem. You can buy a hardware modem for $50 and have $100 left for a 1000MHz Duron. Or you can spend $10 on the softmodem and then have $140 left for the CPU. That $40 on the CPU will give you more than 10% performance increase, leaving you with more performance "while running the softmodem" and even a bigger margin when you're offline (95% of the time).

    To be as good as possible on as many platforms as possible, the signal processing code would have to use integer arithmetic instead of floating-point, because the floating-point performance of x86 class processors varies quite a bit from chip type to chip type.

    Yeah, so? Set your goals realistically. So for the first version it is very acceptable if the release notes say: "Nothing below 1GHz will work. We still need to optimize a bit." From that point onwards, other people will be able to contribute with different skills.

    Yes, you are right, legally, both hardware and software (in case of soft modem) must be certified for connection to phone system. I've been thinking how to handle this (as I definitely won't be able to fund certification of each individual hardware piece+software piece), however, I don't have clear handle on it.

    Development and inital deployment will take place on PBXes. Should individual users chose to ignore the warnings that the modem can not legally be connected to the public net with the Linux driver instead of the windows driver, then that could get that user in trouble. Tough luck.

    Hopefully, someone will want to make an app in sufficient volume that approval is neccesary and cost-efficient. (e.g. a TIVO like application).

    Guy from the phone-company comes to fix the stuff. He finds a phone licenced for a different country. "This is what caused it. We'll fix it for free this time, but never ever connect an unlicenced phone again!"

    Yeah Sure. There is very little that will withstand a lighting strike. And the licencing for different countries differs in details, but not in the core. So, basically, the official licencing for a country guarantees that it will work in your country provided your telephone company has equipment that conforms to the "central office" part of the specs.

    Our local telephone company here in the Netherlands sells ISDNPOTS adapters that provide only 32V as the "at rest" voltage. Turns out some equipment decides that anything below 35 is "not an operational telephone line". The specs say that equipment that acts as if it's a central office or a PBX needs to provide 42-60 Volts as the line voltage in "rest".

    With a big "installed base" of ISDNPOTS adapters, the new equipment gets a hard time, because "everything else works just fine"....
