IE on Ubuntu (Feisty)

2007-06-21 by xpheas
OK, you may wonder why i do something stupid like this,
but i'am working on an new web project and i also want support the ie users...

I was looking for a way to use the ie under Linux and found a package called IEs4Linux
that provides an easy way to install 3 IE versions on Linux.

Here is a little tutorial how to install the IE on Ubuntu Feisty.

OK, first a note:
IEs4Linux is under GPL but IE is not, so you must have a legal Windows copy otherwise installing IE is illegal!
Legal notices

Here we go.

First we have to install wine (skip this step if you already have wine)
Edit the sources.list and add the repositories.
Use your prefered editor to do this. (nano, vi, gedit...)
BASH-Code:
1

sudo nano /etc/apt/sources.list

Add the repositories:
BASH-Code:
1
2

deb http://de.archive.ubuntu.com/ubuntu feisty universe
deb http://wine.budgetdedicated.com/apt feisty main

Refresh the package list and install wine
BASH-Code:
1
2

sudo apt-get update
sudo apt-get install wine cabextract

Installing IEs4Linux

Install IEs4Linux, do this as normal user!
BASH-Code:

4

wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz
tar zxvf ies4linux-latest.tar.gz
cd ies4linux-*
./ies4linux

After a while the installation will finish an you can use your IEs:

from shell:
BASH-Code:

/home/username/bin/ie6
/home/username/bin/ie55
/home/username/bin/ie5

There also should be some nice icons on your Desktop.

Virtual Penis

2007-06-09 by xpheas
This funky Shell-Script calculates the penis length of your computer.

BASH-Code:
1
2
3
4
5
6
7

#!/bin/sh
LC_ALL=C
echo `uptime|grep days|sed 's/.*up \([0-9]*\) day.*/\1\/10+/'; \
cat /proc/cpuinfo|grep MHz|awk '{print $4"/30 +";}'; free|grep '^Mem' \
|awk '{print $3"/1024/3+"}'; df -P -k -x nfs | grep -v 1k \
| awk '{if ($1 ~ "/dev/(scsi|sd)"){ s+= $2} s+= $2;} END \
{print s/1024/50"/15+70";}'`|bc|sed 's/\(.$\)/.\1cm/'

Usage:
Save as vpenis.sh and make it executable (> chmod a+x vpenis.sh)
> ./vpenis.sh

Have fun!

PS: My computers length: 86.2cm *gg*

UPDATE
Thanks to black07 for the bug report!
There was a problem with the code-highlight function, which is fixed now.

YouTube and valid XHTML

2007-06-07 by xpheas
I brodcast some YouTube and Zabim movies on my blog,
The uncool thing is that, that the YouTube and Zabim embed Tag is actually not XHTML valid.

The YouTube embed Tag looks like this:

HTML-Code:
1
2
3
4
5

<object width="425" height="350">
<param name="movie" value="http://www.youtube.com/v/WTC0UvS9mXA"></param>
<param name="wmode" value="transparent"></param>
<embed src="http://www.youtube.com/v/WTC0UvS9mXA" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed>
</object>


It contains the <embed> tag, which is not allowed in XHTML 1.0 Strict.
To make the code valid, i changed the code abrove to something like this:

HTML-Code:
1

<object type="application/x-shockwave-flash" width="425" height="350" data="http://www.youtube.com/v/WTC0UvS9mXA"><param name="movie" value="http://www.youtube.com/v/WTC0UvS9mXA" /></object>


YouTube and Zabim plays well and it's valid XHTML 1.0 Strict!
