Backup / Increase the Guest OS Drive on VirtualBox

Tried to search online for a way to increase the size of a vdi image, and there was no solution available online to do so.
I had windows XP installed on a virtual machine for mail, and testing purposes on the most hated IE6, and the drive ran out of a space, no solution or work around helped me increase it, all the solutions to modify the partition table, etc didn’t work for me.
Here is the simple steps i followed :

Add Another Disk Drive to the Guest OS
Backup the Guest Operating system drive using Norton Ghost to the newly added drive.
Copy the backup to a DVD image (I had to move it to the host drive first)
Make a new Virtual Machine with the new size you want.
Boot the new machine using Norton Ghost drive, and attach the DVD image with the created backup.
Restore the backup from the DVD created using Norton Ghost.
Restart the machine and you should have a working.
Delete the created DVD image, the extra hard disk, and the old machine.

If you have a shorter solution, please share

Installing Zend Server on Ubuntu 10.04

I have been having issues trying to install Zend Server on Ubuntu 10.04 following the steps here http://files.zend.com/help/Zend-Server-5-Community-Edition/zend-server.htm#deb_installation.htm
the problem was because there is a missing dependency for the “libmysqlclient15off” MySQL client library

to solve this, I had to install “libmysqlclient15off” from here (select the one that matches your architecture)

http://archive.ubuntu.com/ubuntu/pool/universe/m/mysql-dfsg-5.0/

Then install it using the command line :

dpkg -i libmysqlclient15off_5.1.30really5.0.83-0ubuntu3_i386.deb

after that running the installation for Zend server from through repositories, will work with no interruptions.

Compress and Split large files under Linux

One of the common problems i used to face is transferring large files from Linux through mediums that doesn’t support large files, especially when it comes to more than 100 GB files, usually that is a virtual machine hard disk, or backup file.

To compress and split files under linux, this command can be used:

tar -cvj large-file.dvi | split -b 1000m -d - "small-files.tar.bz."

This command will compress and split the “large-file.dvi” to many files with size 1000mb for each, giving it the name “small-files.tar.bz.0, small-files.tar.bz.1, etc….”

To join the files together again, this command can be used:

cat small-files.tar.bz.* > large-file.tar.bz

and to extract the output file :

tar -xvj large-file.tar.bz

Recruitment System – One of my projects

I wanted to post this since a while.

The recruitment system is one of the applications I built for cha-international while working there beside developing the Middle East & North Africa travel awards system, mail marketing system, and converting all their servers from windows to Linux.

In brief the system has the following features :

Backend :

Managing countries, Nationalities, Languages, World Areas, System Announcements.

Managing Education Levels, Industries, Titles, Departments, System Reply Messages, Candidate Status, Candidates Classifications, and Quotes.

Testimonials section where the company can post its clients testimonials to be displayed in the frontend.

Managing 2 types of resumes : Uploaded Attachments, and Detailed filled forms Resumes.

Easy form for the data entry team to add the resumes from the backend.

Searching for candidates, using simple forms like name, email or advanced one which contains name, different nationalities, different languages, age, sex, industry, title, keyword in resume, etc.

Consultants area where they can post / close job posting, search for candidates, export word version of resumes, add to their favorite list, recommend them to another consultant.

Consultants also can comment on the resumes, change their availability status to be seen by other consultants, and communicate with the candidate through the reply messages and keep track of those sent messages.

The system has a approval workflow engine, the admins have to check the resume to approve it first.

The system has a privileges section where the administrator can create a new role, assign access to certain areas in the backend to certain role, and assign the roles to system users.

Feedback system where the backend users can communicate with the administrator for support tickets, etc.

Auditrail system where every action in the system is logged.

Frontend:

Simple upload form where users can just upload their resume and simple details.

Advanced profile form where users can fill in all the details, and add many attachments to their profiles.

Listing, Simple search, advanced search for jobs, and applying to them.

Clients area where they can request certain services.

Featured profiles, where a certain profiles selected by the admins showed in frontend.

The project was completely built from scratch using Zend Framework, and right now it has more than 70,000 applicant in its database, and the system is as fast as you see in the videos, these demos were taken with 50,000 record in the database.

Please don’t give me any feedback on the design , I am just a developer.

Here is some videos describing the different features of the system, I will try to post a better quality ones later.

How to Add & Subtract time code in Python

I have been developing some tools for the media production lately, i found a neat way to add or subtract certain amount of seconds to a given time code.

for example i have a video that starts from 12:45:05 and i want to add 59 seconds to it and use the new time.

from datetime import datetime
from datetime import timedelta
 
time = datetime(2009, 1, 1, 12, 45, 05, 0)
 
diff = timedelta(seconds = 59)
 
final_time = time + diff

Installing Python & PyGTK on Mac OsX

Recently i have been asked to develop an application that will work on Linux, and Mac os, so i started developing it on my Ubuntu, i chosed Python as the programming language and PyGTK as the GUI for it.

The application worked fine on my Ubuntu, but when i moved it to Mac OSx (Leopard), i had a problem importing the PyGTK module and the program GUI didn’t run. so i tried to install PyGTK from sources with all its dependencies, but after spending a day doing so i ended up with many errors in compiling the dependencies and finding them.

after some search i found out that i can do this using MacPorts.

so here is the steps i followed :

- Install X11 http://guide.macports.org/#installing.x11

- Install Xcode tools http://guide.macports.org/#installing.xcode

- Install MacPorts http://guide.macports.org/#installing.macports

- Make sure the paths are configured in your shell profile http://guide.macports.org/#installing.shell

- Restart your shell, and follow the next commands :

1- Install Python

sudo port -v install python25

2- Install Python select

sudo port -v install python_select

3- Activate our installed python version

sudo python_select python25

4- Install pygtk

sudo port -v install py25-gtk

5- Install some gnome themes and engines

sudo port -v install gnome-themes
sudo port -v install gtk-nodoka-engine
sudo port -v install gtk-smooth-engine
sudo port -v install gtk2-aurora
sudo port -v install gtk2-clearlooks
sudo port -v install gtk2-extra
sudo port -v install gtk2-industrial
sudo port -v install gtk2-murrine

6- Install theme switch

sudo port -v install gtk-theme-switch

7- Select which theme to be used by your applications by running the theme switch

switch2

Now you can have the applications you develop using python and pygtk running smoothly on mac os leopard.
