  1. Parabolic football? Not even close! on Zero-Gravity Sports League In Development · · Score: 0

    They felt the need to explain why the name was similar to football? With the only word in common being "ball"? I would worry more about explaining why they used "para" from the word "parabolic".

    If you throw a ball in zero gravity, it will travel in a straight line, not along a parabola.

    Gravity makes a thrown ball travel along a parabola. So being designed for zero-g, "paraball" is the very first official ball-based game that has absolutely nothing to do with parabolas.

    Although if you want to pick nits, since the airplane is travelling along a parabola to create a zero-g environment for the players, the ball within the plane is travelling along a parabola relative to the earth. Relative to the playing field (the plane), it's all straight lines.

Many conversations and events from the first book were retold so that they appeared to be the same on the surface, but completely different things were actually happening.

    The end result was a book that was very clever, but wasn't a very good story. It left me feeling that it had soiled the first book.

Mothers and/or Fathers can then take an additional 35 paid weeks off for parental leave after the baby is born. So for a mother, 52 paid weeks off is indeed the maximum.

  5. Denial of Sight Attack on Home Defense, Geek Style? · · Score: 1

    Wow, lots of people advocating violence. My favourite anti-intrusion system is totally passive, and based on fog.

    http://www.fogsecurity.com/area_denial2.php

    Intruders attacking commercial premises know that they will trigger an Intruder Alarm which will summons a Police response via a monitoring station. The crooks are also aware that unless they are unlucky, the Police response is unable to attend in less than seven minutes. The crooks will normally spend those seven minutes removing items from the premises. During that time, they can clean out a fairly large amount of inventory.

    To achieve this however, requires a fairly rapid incursion into the premises, moving around the area at speed to remove equipment or stock. By reducing visibility to less than ½ inch, Fog Security Systems makes movement at all extremely difficult and movement at speed impossible. Fog Security Systems Inc. protects property from intruders by harmlessly reducing visibility to inches within seconds of a break-in.

    For use in a home, you would have to place the fog generators carefully. For a two-story home with sleeping areas on the second floor, you could just place them on the first floor.

    This would work well in a car, too. It's pretty hard to drive a car that is filled with fog. It would be damned difficult to even steal the stereo.

    Many green energy solutions can be implemented in a decentralized manner, instead of in huge projects like you mention. Installing them in this manner could make use of space that could not otherwise be used for energy generation.

    Covering your house's shingles with solar panels would be expensive, but this could provide for much of the electrical needs of your household. For about $14,000, you can buy 24 165w Sharp 1575mm x 826mm solar panels, and save about $500 a year on electricity.

    A 20m tower with a 7m diameter wind turbine could be installed in even a very small inner-city house lot. If you live in a reasonably windy climate, this could generate all the electricity you need for about $25,000.

    I know these are expensive solutions, but certainly not impossible. The prices will come down.

I'm planning on using it to launch a macro via the software program Girder that will send all of the appropriate IR commands out of the USB-UIRT IR blaster/receiver to turn on all the devices and switch their inputs accordingly. That should solve the only problem we have, which is explaining to babysitters how to use the TV.

  18. Re:Healthy future ... on Measuring Pollution In Humans · · Score: 1

    You make some interesting points. As you say, correlation is not causation.

    There are really two points to be made:

    1. Cigarette companies have been targeting youth with their advertising.
    2. Cigarette advertising encourages increased consumption of cigarettes.

    The King and Siegel study is not trying to prove the second point, only the first. It makes no comment on the effectiveness of this advertising, it is only showing that cigarette companies are specifically targeting advertising to youth. It speaks of their intentions, not the results.

    You are right that I did not back up the second point adequately.

    Here are some exerpts from a study published in the Journal of the American Medical Association in 1998:

    This study provides "the first longitudinal evidence to our knowledge that tobacco promotional activities are causally related to the onset of smoking." According to the authors it "provides clear evidence that tobacco industry advertising and promotional activities can influence non-susceptible never-smokers to start the process of becoming addicted to cigarettes ... our data establish that the influence of tobacco promotional activities was present before adolescents showed any susceptibility to become smokers ... we estimate that 34 per cent of all experimentation in California between 1993 and 1996 can be attributed to tobacco promotional activities."

    Here is a quote from Emerson Foote, former Chairman of the Board of McCann-Erickson, which handled $20 million in tobacco account sales:

    "The cigarette industry has been artfully maintaining that cigarette advertising has nothing to do with total sales. This is complete and utter nonsense. I am always amused by the suggestion that advertising, a function that has been shown to increase consumption of virtually every other product, somehow miraculously fails to work for tobacco products."

    Here is a quote from a leaked internal paper by Claude Teague, Assistant Chief in R&D at RJ Reynolds:

    At the outset it should be said that we are presently, and I believe unfairly, constrained from directly promoting cigarettes to the youth market ... if our company is to survive and prosper, over the long term we must get our share of the youth market ... Thus we need new brands designed to be particularly attractive to the young smoker, while ideally at the same time appealing to all smokers ... Perhaps these questions may be best approached by consideration of factors influencing presmokers to try smoking, learn to smoke and become confirmed smokers.

    Actually, until an exemption was made to the Canadian Copyright Act, for the most part, Canadians did not enjoy the right to copy music for personal use. The levy was first introduced at the same time as this exemption, in 1997.

    The best part of this exemption is that Canadians are allowed to make a copy of someone else's music recordings. You don't have to own the original LP/tape/CD/whatever.

    Yes, this means that Canadians are allowed to download music from P2P networks! Unfortunately, the Canadian Copyright Act specifically states that the exemption does not apply if you are "(b) distributing, whether or not for the purpose of trade; (c) communicating to the public by telecommunication".

    It hasn't been tested in court, but it is commonly accepted that sharing music - i.e. allowing uploads - with P2P networks violates these clauses. So Canadians can download from P2P networks, but not upload.

    So a (probably) completely legal alternative for Canadians is to rip mp3 streams from web radio. Sure beats the price-point of iTunes, and makes me feel a lot better about paying that levy on the hundreds of CDRs we go through in the course of software development.

    1. Vote at the machine
    2. The machine asks you for a PIN number.

    4. The machine prints out your vote, your voter registration number, your chosen PIN and the hash on a reciept and gives it to you.

    Later on, a text file is made publically accessible with a row for every vote. Each row would have only the hash and the person they voted for. The algorithm for computing the hash would also be published.

    Anyone who is interested in confirming that their vote was properly recorded can look up their hash in the text file to make sure it lists the person they voted for.

    Anyone who has a spreadsheet can do a recount.

    Any third party with a bit of cryptography knowledge can write a web app for people to confirm that their hash was computed properly.
