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=""></param>

Should be like this:

<object width="425" height="344" data=""
<param name="movie" value=""></param>

Here is the info — Flash Satay: Embedding Flash While Supporting Standards.

I just have wrote about Extract part of FreeRadius” log with a little awk script. Then I decided that it whould be easier and quicker than with Python.

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

Excellent site about CSS!

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:

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.
