In multi user systems, it's usually much safer not to let users change the contents entirely in case there was a mistake or when it was needed to know what has changed by whom and revert the change if required. Drupal supports content revisioning and there are already some contributed modules that exploit this extremely useful feature like revisioning. However when it comes to content deletion, revision system can no longer be used because when a content is deleted, it gets removed from database entirely including all its revisions.

Entity soft delete module has been developed to address this limitation.

In Drupal there are many different methods to turn long forms into multipage/multistep forms. The most known one is perhaps the great ctools module or even custom solutions using Drupal’s form API. However as you may agree with me none of these solutions are really that easy, specially when it comes to Ajax. Therefore many developers in Drupal community tried or still trying to find an even easier method. What I’m going to introduce to you is yet another magical method :).

While ago i was looking for an slider module (implementation of JQuery UI slider module), surprisingly i couldn't find any solution except jSlider Form API which wasn't exactly what i was looking for. So i did what every good Drupal developer does, I wrote a generic slider module and shared it on Drupal.org (jQuery UI Slider Field). I even implemented "jSlider Form API" features.

Several months later and after i published several new minor versions, one of the users mentioned that there is in fact another slider module similar to mine!! SliderField and it was quite old too. He suggested joining forces to prevent duplicate modules. and that's what i did and even more.

It’s funny that whenever someone asks me what I do it takes me few seconds to respond. And the answer I give not at all describes what I do! I usually say I work in the computer field! Or I produce software!! But why ?

In the past few years i read and heard many times that the reason for Windows' vulnerabilities and specially virus attacks is simply because much more computers are running it and it could have been the same for Linux (aka GNU/Linux)!.

First of all i'm glad that this kind of discussions are pupping up so often these days, because it means that Linux's user base is increasing and it attracts more attention everyday. However this point of view also shows its authors' limited understanding of how GNU/Linux and Open Source community work. GNU/Linux is NOT WINDOWS, yes they're both operating systems but they have many fundamental differences. Lets highlight some of these differences  and see how they affect the main topic of this article.
