Inline SVG that Validates

XHTML and SVG are different document types, so it’s not possible to include inline SVG documents in webpages without javascript. However it is possible to use frames to explicitly or implicitly embed SVG documents. The method is similar to embedding flash. The following is the implicit method based on the Flash Satay article.

Microsoft International Keyboard with Dead Keys Extended

Dead keys are useful for typing accented characters like á and ñ, but what if you need to type other european characters like ç and €. Then it’s time to start using the [Right Alt] key!

Install Bandwidth Monitor (vnstat) on Ubuntu

adamkane — Mon, 12 Jan 2009 18:41:18 +0000

Monthly bandwidth monitoring utility:
vnstat + PHP frontend
http://humdi.net/vnstat/
http://www.sqweek.com/sqweek/index.php?p=1

The commands in this HOWTO must be entered in the terminal:
Applications -> Accessories -> Terminal

Install vnstat:
sudo apt-get install vnstat

Start and test vnstat:
Note which interfaces are active on your PC.
vnstat -u -i eth0 vnstat -u -i eth1

Now you can generate text reports of your monthly bandwidth usage. I use eth1 in the following examples, but you may be using eth0 or both eth0 and eth1.

Daily bandwidth report.
vnstat -i eth1 -d

Hourly bandwidth report.
vnstat -i eth1 -h

Monthly bandwidth report.
vnstat -i eth1 -m

Real time speed report.
vnstat -i eth1 -l

Install ubuntu-tweak:
http://ubuntu-tweak.com/downloads
sudo gedit /etc/apt/sources.list

Add the following line to the end of the file (if the line doesn’t already exist).
deb http://ppa.launchpad.net/tualatrix/ubuntu intrepid main

Then update and install.
sudo apt-get update sudo apt-get install ubuntu-tweak

Create a startup script for vnstat:
(eth0 is the device name for my wired connection and eth1 is the name for my wireless connection. Create a separate entry for each internet interface that you will be monitoring.)

Applications -> System Tools -> Ubuntu Tweak -> Startup -> Autostart -> Add
Name: vnstat eth1 Command: vnstat -u -i eth1 Comment: [blank]

If you find the above reports useful, then you are done. If you would like to generate pretty reports that you can bookmark in your browser, then continue further.

Install and start XAMPP or LAMP:
http://humanlanguage.wordpress.com/2006/12/03/install-xampp-on-ubuntu/
http://humanlanguage.wordpress.com/2006/12/03/install-lamp-on-ubuntu/

Download vnstat PHP frontend to your desktop and install:
cd ~/Desktop wget http://www.sqweek.com/sqweek/files/vnstat_php_frontend-1.4.1.tar.gz tar xvfz vnstat_php_frontend*.tar.gz -C ~/public_html cd ~/public_html/vnstat_php_frontend* mv vnstat_php_frontend* vnstat_php_frontend gedit config.php

Change lines 32, 39-41, 56:
$iface_list = array('eth0', 'eth1', 'sixxs'); ... $iface_title['eth0'] = 'Internal'; $iface_title['eth1'] = 'Internet'; $iface_title['sixxs'] = 'SixXS IPv6'; ... $vnstat_bin = '';

to:
$iface_list = array('eth1'); ... // $iface_title['eth0'] = 'Internal'; $iface_title['eth1'] = 'Internet'; // $iface_title['sixxs'] = 'SixXS IPv6'; ... $vnstat_bin = '/usr/bin/vnstat';

or something similar depending on which internet interfaces you are using.
(See Start and test vnstat above.)
Save and close the file.

Open vnstat PHP frontend:
http://localhost/username/vnstat_php_frontend

Install LAMP on Ubuntu

How to install LAMP on Ubuntu:
Linux + Apache2 + MySQL + PHP5

Terminal:
The following commands must be entered in the terminal.
Applications -> Accessories -> Terminal

Choose one of the following setups:

Apache2 + PHP4 + MySQL4
sudo apt-get install apache2 php4 mysql-client mysql-server phpmyadmin php4-mysql

Apache2 + PHP5 + MySQL4
sudo apt-get install apache2 php5 mysql-client mysql-server phpmyadmin php5-mysql

Apache2 + PHP5 + MySQL5
sudo apt-get install apache2 php5 mysql-client-5.0 mysql-server-5.0 phpmyadmin php5-mysql

Installation options:
You will be asked to choose a password for MySQL.
Ubuntu will not allow you to enter a blank password.
You will be asked to choose a web server for phpMyAdmin. Choose apache2.

Start Apache/MySQL:
sudo /etc/init.d/apache2 start sudo /etc/init.d/mysql start

Restart Apache/MySQL (if necessary):
sudo /etc/init.d/apache2 restart sudo /etc/init.d/mysql restart

Stop Apache/MySQL (if necessary):
sudo /etc/init.d/apache2 stop sudo /etc/init.d/mysql stop

Apache2 and MySQL will not start if XAMPP is also running. If you have both, you must stop one before starting the other:
cd /opt/lampp sudo ./lampp stop

Publish:
LAMP uses /var/www as the root web directory, but you can publish pages in your home directory this way.
cd ~ mkdir public_html sudo ln -s ~/public_html /var/www/$USER

Now any files and folders you place in ~/public_html will be
published to your personal webserver.

Open your new webpages at:
http://localhost/username/

Open phpmyadmin in your browser:
http://localhost/phpmyadmin/

Log into phpmyadmin with your MySQL password:
Name: root Password: [Enter password chosen during installation.]

You can edit additional phpmyadmin options by setting an admin password:
sudo htpasswd /etc/phpmyadmin/htpasswd.setup admin

You’ll be asked for your current user password. Then you’ll be asked to enter and re-enter an admin password.

After you have an admin password, you can access phpmyadmin setup here:
http://localhost/phpmyadmin/setup/

Install XAMPP on Ubuntu

adamkane — Sun, 03 Dec 2006 11:39:53 +0000

Updated:
10 January 2009

How to obtain the latest version of LAMP on Ubuntu:
(Apache 2.2 + MySQL 5.1 + PHP 5.2 + PERL 5.10 +PEAR + SQLite + ProFTPD + phpMyAdmin + Webalizer + phpSQLiteAdmin + XAMPP Control Panel)
http://www.ubuntuforums.org/223410
http://www.apachefriends.org/f/viewtopic.php?t=21531#108517

The commands in this HOWTO must be entered in the terminal:
Applications -> Accessories -> Terminal

Download XAMPP to your desktop and extract the files:
http://apachefriends.org/xampp-linux
cd ~/Desktop wget http://www.apachefriends.org/download.php?xampp-linux-1.7.1.tar.gz sudo tar xvfz xampp-linux*.tar.gz -C /opt

Create a XAMPP start menu entry:
cd ~/.local/share/applications gedit xampp-control-panel.desktop

Paste the following into the open file:
[Desktop Entry] Comment=Start/Stop XAMPP Name=XAMPP Control Panel Exec=gksudo "python /opt/lampp/share/xampp-control-panel/xampp-control-panel.py" Icon[en_CA]=/usr/share/icons/Tango/scalable/devices/network-wired.svg Encoding=UTF-8 Terminal=false Name[en_CA]=XAMPP Control Panel Comment[en_CA]=Start/Stop XAMPP Type=Application Icon=/usr/share/icons/Tango/scalable/devices/network-wired.svg

[Desktop Entry] Comment=Start/Stop XAMPP Name=XAMPP Control Panel Exec=gksudo /opt/lampp/share/xampp-control-panel/xampp-control-panel Icon[en_CA]=/opt/lampp/htdocs/xampp/img/logo-small.gif Encoding=UTF-8 Terminal=false Name[en_CA]=XAMPP Control Panel Comment[en_CA]=Start/Stop XAMPP Type=Application Icon=/opt/lampp/htdocs/xampp/img/logo-small.gif

Save and close the file.

Publish:
XAMPP uses /opt/lampp/htdocs as the root web directory, but you can publish pages in your home directory this way.
cd ~ mkdir public_html sudo ln -s ~/public_html /opt/lampp/htdocs/$USER

Now any files and folders you place in ~/public_html will be
published to your personal webserver.

Start XAMPP via the terminal:
cd /opt/lampp sudo ./lampp start

Stop XAMPP (if necessary):
cd /opt/lampp sudo ./lampp stop

Via the XAMPP Control Panel:
Applications -> Other -> XAMPP Control Panel

If Apache2 or MySQL is already running, then XAMPP will not start. You must stop these applications, if you want to use XAMPP:
sudo /etc/init.d/apache2 stop sudo /etc/init.d/mysql stop

PHP5 is the default, but you can switch between PHP4 and PHP5, if you like:
cd /opt/lampp sudo ./lampp php4 sudo ./lampp php5

Open your new webpages at:
http://localhost/username/

Security:
http://apachefriends.org/xampp-linux/381

1. The MySQL root user has a blank password.
2. MySQL is accessible via your local network.
3. ProFTPD has user “nobody” with password “lampp”.
4. PhpMyAdmin is accessible via the local network.
5. Examples are accessible via the local network.
6. MySQL and Apache running under the same user “nobody”.

To configure some of the security features of xampp:
cd /opt/lampp sudo ./lampp security
