    "It was mentioned on CNN that the new prime number discovered recently is four times bigger than the previous record." --John Blasik

    How to prove that all odd numbers are prime? Well, this problem has different solutions whether you are a:

    • Mathematician: 1 is prime, 3 is prime, 5 is prime, 7 is prime, and by induction we have that all the odd integers are prime.

    • Measure nontheorist: There are exactly as many odd numbers as primes (Euclid, Cantor), and exactly one even prime (namely 2), so there must be exactly one odd nonprime (namely 1).

    Yeah, I couldn't believe it when I saw it. I thought it must have been just for the first step in Zope, then I searched where the files (template and other elements) were saved so I could access them directly with my editor of choice. No go, it's inside a database.

    I gave up Zope and stuck to PHP soon after that (and the fact I could not wrap my mind around their 'TAL' thingy, call me dumb).

  9. PHP vs Zope, Pearl vs Python on Learning PHP 5 · · Score: 4, Interesting
    I had to use Perl for a project some time back. It was quick and dirty and did the job. At the same time I learned python without managing to apply it to the project. I recognized that I liked python better, but perl was faster to implement.

    Slightly later I did a web project where some interaction was necessary. Instead of my old cgi-scripts or DHTML, I started it in PHP and Zope, as a newbie in both. While recognizing that Zope seems very clean I was totally unable to wrap my head around its basic concepts ('TAL' anyone ?). In one afternoon I had PHP installed and a 140 pages of PHP converted from HTML, up and running. Going from HTML to basic PHP takes about 5 minutes.

    So, while I regret to say that, some languages look cool but others just do the job. PHP is certainly one of the latter.

    I have friends who do mountain rescue work. They've tested a communication system (mike/phones) for use when the chopper is hovering loudly above. The 'phones' are flat and go under the top of the helmet, using bone conduction on the skull.

It was a couple years ago, so it may have improved.

    I've heard that washing your cat daily with mild soap and warm water removes most of the allergens from the fur (it does nothing to the saliva though). Supposedly if you start with a young cat you can train it to like the shower, although that sounds like a sure way to end up with facial reconstructive surgery if you try it with an older cat...

    "You can own a dog but you can only feed a cat..."

    More on topic, this genetically enhanced cat is a good idea. I've had cats and dogs until I was 16. Then I moves to the city away from my parents. Upon returning after a month away... I was allergic to the cat ! I've kept this allergy and although I like to pet my current neighbor's cat I can't have one nearby for long. Yes, I know you can shower your cat daily to greatly disminish the allergens, but I think it's probably a lot more life-threatening to clean a cat than to live in an iron lung.

    As for what I think of dogs, I had a few run-ins with those social parasites in the US and their often 'religiously stupid' owners which led to this piece.

    I assumed (incorrectly as you pointed out) that the alcohol would come from urine. Since their tests shows it accumulate in the recycled water, maybe it comes from the dishwashing water (more reasons to finish all the glasses then). I'll let you know how it worked out in 2006 after I get back !!!

    BTW, in case anyone is wondering why we just don't melt some of the 4km of ice we are sitting over is that in winter it's too cold (-84C) to get out with a Caterpillar to fill the melter with snow.

    I'll be wintering over at Dome C in 2005 (in the center of Antarctica). We'll be taking with us a prototype recycling system designed by the European Space Agency, able to recyle grey waters (also black 'waters' in 2006, but it will be after my time). So, yes, we'll be drinking and showering with past shower and dishwasher water... I won't go into details but the system has 4 successive filtering systems, and the water is so pure in the end that we have to add minerals to it. The funny thing is that the only thing that passes through unfiltered is alcohol; so since the water is recycled at only 75% (100% in 2006), it means that the alcohol content of the water will increase over time. Yum, I'm looking forward to the showers after a few months of pissing beer !!!
