The mystery of CGI

Checking the small print of my web host package, it appears I’m supposed to be able to run CGI scripts written in Perl, PHP or Python.

So, I set out to test this theory. I looked up Hello World CGI scripts for all three language, put them on the host and tried to access them.

The future of my sites

Currently, I have two websites. There’s a site built by Indoculate which I haven’t touched in years, and there’s this blog, powered by Word Press.

On Complex Numbers

OK, so when you went to school, they taught you how to count. You know, 1, 2, 3, 4, that kind of thing. Then a little later, they taught you how to add, and later how to subtract. Then, after a while, they taught you that if you subtract a big number from a small one, you get a special new kind of number: a negative number.

Later they teach you to multiply and divide, and you come across another new type of number: fractions. (Ah yes, every students’ favourit topic!)

Most people’s maths education stops there, but there are in fact other kinds of numbers out there that you haven’t learned about yet. Wanna see?

Know your intervals

OK, so some more music theory, people!

Generally speaking, the human ear (or more exactly, the human brain) doesn’t respond to pitch, it responds to pitch relationships. You’ve probably seen that picture with the blue squares, and each blue square has a different background colour, and it makes the blue squares appear different shades of blue, even though they’re actually identical. Or, see this nausiating picture:

Colour illusion.

See those green and blue stripes? You know what? They’re both the same colou!

Musical notes are similar; if you play G after just having played C, it sounds natural and harmonious. But play G when you’ve just been playing B♭ and it sounds very different.

Toil and trouble

Well, let me see now…

I took a week off work and ended up roofing the garage. Not, of course, that my mum is in any way grateful to me for wasting my entire week doing a job that she was too exhausted to do herself. No, she’s just whining that it’s not all perfect and wonderful like they showed in the demo video. Funny how a roof not laid by professionals does not yield a professional finish, eh? Perhaps she should have paid out £4,000 to have the professionals come and do it? Then I could have enjoyed my damned week!

You’d think having a roof that no longer leaks like a seive would make her happy, but nooo

Cathedral cities

On Sunday, I bundled my mum into the car and drove to the city of Ely. Apparently they have a rather large cathedral there. And what do all cathedrals have?

Well, one thing they have is huge doorways, enormous stained glass windows and towering spires. And Ely Cathedral is no exception. It also houses a rather large pipe organ — 83 stops according to NPOR. The organ is pretty impressive to look at as well!

Are you nervous?

So, last weekend the annual gathering of the NERV clan occurred. Suffice it to say this involved a bunch of Internet weirdos driving out to Ancaster, camping out by the lake. There was beer, fly-up breakfasts, barbecue suppers, karting, bowling and paint-balling.
