Miniature Earth — valid XHTML markup

BTW, to have XHTML validated page, it was necessary to change the code provided by YouTube.

For Miniature Earth they provided:

<object width="425" height="344">
<param name="movie" value="http://www.youtube.com/v/kIUCTbi_XZs"></param>
<embed src="http://www.youtube.com/v/kIUCTbi_XZs"
   type="application/x-shockwave-flash" width="425" height="344"></embed>
</object>

Should be like this:

<object width="425" height="344" data="http://www.youtube.com/v/kIUCTbi_XZs"
    type="application/x-shockwave-flash">
<param name="movie" value="http://www.youtube.com/v/kIUCTbi_XZs"></param>
</object>

Here is a Python script, which does the same (and written in the same way):

Excellent site about CSS!

The very nice site for beginners — http://css.maxdesign.com.au/. A lot of information, examples, step-by-step solutions.

BTW, there i’ve found another good page, Floats, Margins and IE — examples and workarounds for MSIE’s problem related to rendering floats.

Extract part of FreeRadius’ log

Today I needed to extract some records from FreeRadius” log — those with Called- or Calling-Station-Id like XXXYYZ[0-2]. Started to type #!/usr/bin/python in new file, but «suddenly» decided to do it with awk.

If you don’t know — FreeRadius’s log contains «sections» separated by empty lines. Every section contains records Called-Staion-Id = <number> (or Calling-Station-Id), and i need to extract sections regarding calls to/from specific numbers.

So, the five-minutes-working-code:

True Knowledge — “human” answer to questions?

True Knowledge Ltd launched a test service — True Knowledge (registration required, free).
Surely, I wanted to take a look :-)

First, I asked «How many seas on Earth?». I have got a very good answer:

Next I asked whether Bill Gates is clever (sorry):

Using SPARK module

I have finally formatted my «old» paper about using Python’s SPARK module for compiling «little languages» and code generation — as example, for scanning, parsing, analyzing a simple configuration file for configuring HTB shaper and generating a code (shell script).

I put it as a staic page — here.

Language Switcher

I have found a great plugin for WordPress: Language Switcher.

Just one issue so far: NextGEN Gallery widget does not allow to edit its title to switch between languages.

Well, and it’s nesessary to edit theme files — replace „smth” with __(‘smth”), and «correct» language file (<lang>.po, and converting to .mo with command msgfmt <lang>.po -o <lang>.mo).
