Python Programming!

I have tried Python earlier, but its syntax didn’t make sense to me. Several weeks later, I wanted write a small app, so, I thought, why not try to write it in Python.. Just give it a try… So, I start writing the app in Python, it took longer than it should have, but it was done! Now, I can program in Python. I am so happy that I have finished writing my app in Python. Looks like Python has been added to my portfolio of programming languages.

ZenCrypt — PHP Encoder

Last night, I was searching the internet for PHP Encoders, I always knew that ZendGuard and IONCUBE are the best. However, I thought of giving others a chance. While searching I came across ZenCrypt. One of the good things about it that it doesn’t need a loader on the server-side. Thus, the scripts are self-decodable. But this makes it easy to decrypt. On thier website, they have two scripts. One is the source, and the other is the encoded script.

My Attempt to understand its way of encoding to see if it worth the USD45.

Source PHP Code:

Conclusion:

What I see that it doesn’t worth the the USD45. Maybe if it was encoded with ZendGuard or ionCube and produces a file that requires a PHP Loader. Just like PHPCipher.
However, from this attempt. I thought that I will write my own encoder. It will be using the same method, however, the output will be encoded in both ZendGuard and ionCube. Stay tuned!

A new year arrives and new projects to come

A new year arrived, and new projects are arriving… My friend Marwan and myself started having several projects to be developed for the Maemo powered devices. However, after discussion today, we have agreed on developing stuff to be cross platform. Most of our development well be in Python GTK.

The agreement is that Marwan will do most of the development, I will be maintaining the projects. I will be responsible of the packaging and bug fixing and some development. Marwan will be doing the core of the applications.

We will be registering a new domain and it will be dedicated for our joint projects. We have lots of ideas, so wish us luck!!

Simple Webserver in Python

Sometimes I need a simple webserver for serving files for my kickstart installations. I have found a simple solution:

python -m SimpleHTTPServer 80

This creates a simple Webserver on port 80 and its root path is the directory it ran from. For more details about it, visit python docs: http://docs.python.org/library/simplehttpserver.html

I ported Template Parser from CodeIgniter to Kohana

I have been using CodeIgniter for many of my php development projects. However, recently, I have knew about Kohanaphp framework, its a framework that is based on CodeIgniter, but is Strict PHP5 OO. That’s something that I love, since I am a Java programmer and in total love with OO (Object Oriented) Programming.
However, Kohanaphp framework didn’t have a template parser, or let me say an alternate syntax template engine. CodeIgniter did, although its not full-blown template parsing solution, but it does the job perfectly for me. I started using Kohanaphp for one of my php projects, and I wanted to reuse some of my views which were done using CI template parser syntax. So, I ported the parser class to Kohana.
The Code is hosted on http://code.google.com/p/kohana-template-parser/

PHP Framework — CodeIgniter

Few days ago, I was searching for a PHP framework that I can use for my web development. I found many Frameworks available, so I have set my search criteria to:
1. Ease of Use
2. Object Oriented
3. Good Community base
4. Flexible License, Preferably BSD — For Development of Commercial Apps.

I have came up with few, and one of them was CodeIgniter.
Such a wonderful Framework to work with.

No More Python — Back to Java

Well, I tried to use Python instead of Java… But I couldn’t succeed. Although, I am a very fast learner, but Python syntax and usability didn’t make sense to me. I am back to Java programming.
