OSScamp Talks
by sanchitgulati on Oct.04, 2009, under Open Source, Osscamp
If you are wondering what to talk about at event, here is a guide to get you going.
If you are planning to attend osscamp then you must be part of IT world, maybe as a student or as a professional developer. So, you must also have used various softwares, library, technology either proprietary or open source. Osscamp is a place to share the same knowledge with all us. So the talk would be either about some framework you used on your php project or any c/c++ library you used to create GUI application or maybe about the some API. Or you and your friends maybe in involved in some open source project from which you require developers from your vicinity, osscamp is the place to be, a place to share, a place to talk. What else? I am out of ideas but if you are some open source enthusiast and know about any other way to use this platform then please, Osscamp would be proud to host you.
PHP:server-side scripting language
by sanchitgulati on Oct.02, 2009, under Open Source, php
PHP, stands for PHP: Hypertext Preprocessor, is a widely used, general-purpose scripting language that was originally designed for web development, to produce dynamic web pages. It can be embedded into HTML and generally runs on a web server, which needs to be configured to process PHP code and create web
page content from it.You can read more from wiki.
To learn php,you would require to install Apache, MySQL, PHP on your local machine.
If using Windows : Install AppServ or Wamp . ( Appsevr for no0bs)- ( Latest Stable release for AppServ 2.5.10)
If using Linux : Install lamp ( Linux Apache Mysql Php )
Further Tutorial are guided according to Appsevr installation.
Step 1.
Tutorial on this link is self explaining.
Step 2.
Checking the installation:
Open firefox or any other broswer and typie localhost in address bar ( this is the space where you type facebook.com )
If you see the html page with “The AppServ Open Project – 2.5.10 for Windows”,then congrats.
Open “http://localhost/phpinfo.php” to know more about php-server installed.
Step 3.
Appsevr store all public html files “C:\AppServ\www\” – Default Location
Step 4.
Create a new file in the above folder with extension php , example hello.php ( Not hello.php.txt)
Edit the file using Notepad and type in the following code
<html>
<body>
<?php
echo “Hello World”;
?>
</body>
</html>
Step 5.
In your broswer open “localhost/hello.php”
You should be seeing a html page with “Hello World”.
Basic PHP Syntax
A PHP scripting block always starts with <?php and ends with ?>. A PHP scripting block can be placed anywhere in the html document,as you can see in example above.
OUTPUT
`echo` is used for printing strings or variable,similar to printf() or cout in c/c++ .
Also,
echo (“Hello World”);
printf(“Hello World”);
INPUT
As php is server-side scripting language it doesn’t not take inputs like c/c++ but accepts arguments in the form of GET or POST .Which is out of the scope of this tutorial. #WaitForOurWorkshop
VARIABLE
All variables in PHP start with a $ sign symbol and carries no datatype,So we don’t need separate variable for int,float or char.
<?php
$strg = “Hello World”;
echo (“$strg”);
$x=16;
echo $x;
?>
FURTHER LESSONS
Operators,If…Else,Switch,Arrays,While Loops,For Loops,Functions are similar to c/c++ you can learn about them on http://www.w3schools.com/PHP/
IDE (Integrated development Enviroment)
There are many open source as well as proprietary software available for easy development of php scripts.Notepad++ or PHPeclipse (Plug-in to Eclipse) works great on windows or you can spend thousands for Adobe Dreamweaver, which is the best option available to industry as of now.For linux machine try gPHPEdit or Codeblocks
LINUX INSTALLATION
Blog on how to install and configure LAMP on linux machine will follow shortly.Atleast I hope so.
DOUBTS AND QUERY
You can ask any doubt on php or any other open source technology on http://cuclante.com/forum/
How to go about with a new Linux Distro : Ubuntu
by mage on Sep.25, 2009, under Open Source
Well as many of the people are confused of linux, this tutorial might just help you :
INTERNET
> To configure internet on your ubuntu OS, first goto your network manager and select your connection/interface.
> It would be set to automatic DHCP, to set a static IP. Right click on the network manager and edit prefrenced, now here specify your ip,gateway,netmask and DNS settings.
> Ubuntu unlike windows has an advantageous feature of Proxy settings. You can apply proxy for every application by specifying it once at System>Administration>Network Proxy
MULTIMEDIA
> Another problem that ppl face is in understanding why linux cannot play mpeg formats by default.
> To start playing your mp3,flv,wav etc files, you can either install vlc player or you can install the gstreamer plugins for default players(Totem, Audacious).
> To install VLC : goto Application>Accessories>Terminal and run this command.
$sudo apt-get install vlc
> To set up gstreamer plugins, just run the type of multimedia file and it’d install the related plugin automatically.
INSTALLING SOFTWARES
Considering ubuntu, it follows the debian color.
You have 3 ways to install any application on ubuntu :
1. Using Ubuntu repository (apt-get).
> Ubuntu has a repository and a method to fetch it on your machine, so that installation occurs without any pain.
> You can find maximum no. of softwares in the repository for installation. To check all of them goto Application>Add/Remove application and select the drop down box to All Available Applications.
> These are a list of applications that you can install without hastle.
Using binaries.
When surfing for a software and you come accross binary version, select the .deb version or the ubuntu recomended version for installation.
Binaries are another easy way of installing a software, now after downloading just double click your .deb file and it’d install it automatically
Compiling program from Source.
When Compiling from source you’d probably have a .tar.gz or other format compressed file.
extract that file to a location.. and in your terminal traverse to that path.
Now for installation from source you require 3 steps :
- configuration
- make install file
- execute install file
Configuration
This process checks whether the system has everything required to install the application, the compilers and libraries to be precise.
You can configure the application by running this file.
mage@h4ck-b0x:~/software_directory$ ./configure
If this runs without error, then proceed to next step otherwise keep installing the compilers and libraries on which it is dependent upon, uptill configure file runs successfully.
MAKE
In this process we tend to make (compile) all the files to create an installation file for the application.
the command for this would be simple :
mage@h4ck-b0x:~/software_directory$ make
INSTALL
In this process we finally compile and execute the installation file,
mage@h4ck-b0x:~/software_directory$ make install
If all the process work in order… your s/w would be ready to go.
How to install your new Linux Distro : Ubuntu
by mage on Sep.25, 2009, under Open Source
Installation :
You can easily install ubuntu on your laptop/desktop via 2 methods.
1. Installing it inside windows’ partition.
- This one is really easy.
- When working on windows, put the Ubuntu Live CD inside the CD-ROM.
- In the AutoPlay menu launch the Install inside Windows feature.
- Select the desired options and here you have you ubuntu running fine.
PS- Installing it in supposing D drive would lead all the contents of D drive inaccessible from Ubuntu.
2. Installing on a separate partition.
- Put in your Ubuntu Live CD and reboot your computer.
- Now boot from your CD-ROM and enter into the Ubuntu Live CD.
- Now select the Install feature. A installer much like windows one would pop up.
- Follow the options that occur blindly except for the partition manager.
- Make sure you select it to manually specify the partitions or else your whole HDD would get formated.
- In the partition manager, you would get the partitions on HDD, you can recognize them with there size. For eg. 106 GB partition is supposed to be my E drive… similarily.
- Select the one you want to format and install ubuntu on then click on edit partition.
- Format the partition to ext3/ext4 format, and mark, use this space as ‘/’
- Now click on Next, it would ask you to create a swap partition, if you have enough memory on your RAM click on continue, other wise create another partition atleast 256mb and use it as swap.
- Finally enter remaining details and you are good to go.
Hope this article helps you install Linux on your machine.
What is Open Source : Introduction
by mage on Aug.31, 2009, under Open Source
Well many people don’t know about it… they know that cuclante is about it but don’t really know it.
This blog post will clear your doubts 
What is Open Source :
Well open source is a form of technology, its main aim is to provide source code of the softwares that we use daily, so that it can be used by contributors to develop it more and according to users need and security. As the name says the source code is open.
Why should i use Open Source :
If you are an end-user, nothing can be better for you. All your daily needs application are available for free, plus because of open contribution a lot of programmers are working on it, leading to a good end product.
I mean firefox is open source its free and its better than internet explorer. VLC is open source and is a favouriate of all isn’t it 
If you are a developer, you get to show your ability in application writting. taking an example, if im good at writting security for applications then i can contribute same code to many softwares. It gives me the freedom to write codes, what i want and for whom i want. Im not bound to a superior guy forcing me to develop an applet of which i have no information about.
Open Source and World :
Well Open Source has spread a lot lately, Google has shown surprisingly huge response in Open Source. All its latest applications are open source (chrome browser, android OS, Chrome OS). Apple uses most of the Open Source apps in its OSX… being frank it is the best company to optimise open source to the fullest.
Open Source Addiction :
Well once a person starts using open source technology, he becomes a fan of it… and this technology fantasises him so much that he keeps on going into it
Open Source and India :
A good example of an open source s/w from india is Maya-Vi (developed by IIT).
Various organisations support Open Source technologies in india, primarily being OSScamp, Barcamp, OSScube you can google them and be a part of it.
