Okay, first you need several pictures of same location in different angle. In my example I take pictures inside of my university mosque.

Nice picture right? FYI this picture taken with Nokia 6288 with 2 Megapixel camera. A very outdated phone, but still do it’s job.

We need to stitch the picture together to make a panoramic looks. Open Windows Live Photo Gallery, it’s freeware courtesy of Windows Live.

Select the picture you want to stitch together, and from the toolbar choose Make and Create Panoramic Photo. Wait several seconds till your picture ready and save the results.

You’re almost done!.  The black corner is the angle that is not included in source picture. You can fix that by take the picture of that angle or just let Photoshop CS5 fill the blank.

Open your panoramic picture with Photoshop CS5

Select the black section with Magic Wand Tool, go to Edit and choose Fill (Shift+F5).

Make sure you use Content-Aware and click OK. Let’s Photoshop do it’s magic.

Done!.

I found out one of my favourite IDE in Windows that support JAVA programming is also available on Linux, it is NetBeans. Netbeans is free Integrated Development Environment (IDE) that supports a lot of languages, including Java, JavaScript, PHP, Python, Ruby, C/C++ and more. NetBeans is written in Java and runs with Java Virtual Machine (JVM) installed. For Java development functionality you must install JDK first, but for other languages you can just install JVM.

Install JDK/JRE Ubuntu Linux

Okay, let’s start with installing JDK and JRE. There are two ways Installing JDK and JRE, the easy way is from Synaptic Package Manager and the hard way is install from .bin file. Installing from Synaptic Package Manager is the best way when you have internet connection or any access to repository (DVD, server, etc). But if your computer don’t have any access to repository server, you can download .bin file from Sun Website from other computer and install it on the computer that you want.

Option 1
First lets start with the easy way, install from Synaptic. Make sure you have the Multiverse repository enabled.

System > Administration > Software Source > Select Multisource > Close

Open your terminal and type the following command to install JDK and JRE

$ sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk

Wait till it download and install, depend on your connection it should take several minutes.
Make sure the correct version is used by using this command

$ sudo update-java-alternatives –s java-6-sun

—

Option 2

For those who want to install the hard way, first download JDK and JRE from Sun. You will get .bin file.

Open your terminal, then go to directory where the download file is, and make sure the file is executable.

cd /directory/where/you/download/file
sudo chmod +x filename

Install the file with this command

sudo ./filename

Make sure the correct version is used by using this command

$ sudo update-java-alternatives –s java-6-sun

Install Netbeans Ubuntu Linux

Option 1
Download Netbeans from here and save it to your computer. Let’s say the file is called “netbeans-6.8-ml-linux.sh”. Run your terminal and change directory to where you download the file.

$ cd /direcory/where/you/download/file

Make sure the file is present by using ls command. Finally execute the following command

$ sudo ./netbeans-6.8-ml-linux

After completing command, you will see installer that will install NetBeans into /opt directory. Finish!.

Option 2
Alternatively you can also install using Synaptic Package Manager, just execute the following command.

$sudo apt-get install netbeans

Finish!.

The answer is to let your system scan for the fastest server available. You will need to launch Software Sources tool, which can be found in

System > Administration > Software Sources

This administrative menu will allow you to change the location of your preferred repository, and change items within the repository you want to subscribe to. You will have the most software available if all boxes are checked.

From ‘Ubuntu Software’ tab select ‘Other’ from ‘Download from:’ drop-down menu and you’ll be given a list of available server sorted with country.

To have your system test and find the faster server you can select the ‘Select Best Server’ option, which will try to connect to each repository server mirror and find the fastest response. After the process done, it will select the fastest server available and you can either change it or run the process again until you’re satisfied.

note: Tested on Ubuntu 8.04 and 9.10. Your mileage may vary. Try to run the process two or three times until you find the good one. Repository mirror speeds can fluctuate based on many factors (e.g Traffic).

So I assume you already have squid installed as proxy server on your machine, and run without any trouble. You need to install a software called sqstat that will monitor your squid access in real time.

Steps to install and configure sqstat:

1. Download sqstat packet
   [root@rendy ~]# wget http://samm.kiev.ua/sqstat/sqstat-1.20.tar.gz
2. Extract sqstat packet that you just download
   [root@rendy ~]# tar -zxvf sqstat-1.20.tar.gz
3. Move directory that you just extract to your webserver directory
   [root@rendy ~]# mv sqstat-1.20 /var/www/html/sqstat
4. Configure you config.inc.php in your sqstat directory
   [root@rendy ~]# cd /var/www/html/sqstat/
   [root@rendy sqstat]# mv config.inc.php.defaults config.inc.php
   [root@rendy sqstat]# vi config.inc.phpchange this line DEFINE(“SQSTAT_SHOWLEN”,60); to DEFINE(“SQSTAT_SHOWLEN”,100); and save the configuration.
5. Edit your squid configuration
   [root@rendy ~]# vi /usr/local/squid/etc/squid.conf
   ##add this line to your squid config fileacl manager proto cache_object
   acl webserver src 192.168.1.1/255.255.255.000 ##Edit with your own IP address
   http_access allow manager webserver
   http_access deny manager

   ##save your config file

6. You’re ready, now time to test, Try open your browser and access http://your.proxy.server/sqstat/sqstat.php

You good to go!
