What are Version Control Systems (VCS)? Since not every developer is familiar with version control systems as they should be, I would like to start by explaining what are these systems, so everybody is on the same page. Version control systems (VCS)  are systems that can keep track of the multiple versions of the files that make part of a project. They are also know  revision control systems  or  source control systems . The main goal of these systems is to keep an archive of the changes done to each project file, so it is possible to: Recover any past version of file Compare two versions of a file and see the actual changes done on the file contents See which developer was responsible for each change Undo inconvenient changes by reverting to past versions Why Using Version Control System is Important for All Developers? Looking above to what you can do using a VCS, it should be clear why these systems are important for all developers. Still, let me...

10 Golden Rules of Project Risk Management: http://www.projectsmart.co.uk/pdf/10-golden-rules-of-project-risk-management.pdf 5 Essential Characteristics of a Project Manager: There are lots of different types of project managers in the world and they all approach their jobs in a different way. I have worked with a wide variety of different sorts of people in this role and feel that there is no classic project manager stereotype which I could try and shoehorn them all into. However, they also tend to have some very clearly defined characteristics in common, and by looking at the most importance of these it is clear that you need certain qualities to survive and prosper in this job. 1.

I could talk about the the upcoming premium services, that are almost ready for launch. I could also talk about several PHP conferences that I have attended as a speaker. But no, I have already talked a lot about those subjects in previous posts. In this end of year post, I will be talking about a single PHP class. Not just any class, but the class that made me create the PHPClasses site: Forms Generation and Validation. http://www.phpclasses.org/formsgeneration But let me tell you why this class is so important to PHPClasses site and also tens of thousands of PHP developers that use it. - The story of the PHPClasses site and the forms class I have started working with PHP around 1997, still in the PHP 2 beta days.

PHPClasses site activity on Twitter Before proceeding to the main topic of this post, I would like to keep you up with an experiment that I am carrying on with the PHPClasses site. Nowadays, I hardly have time to do everything I wanted, I have even less time to keep watching on the activities of my friends. So, I always questioned the interest of micro-blogging platforms like Twitter. http://twitter.com/ Micro-blogging platforms can send short messages to mobile phones or instant messaging programs when a Twitter account is updated with new entries. A couple of weeks ago, a personal friend of mine started an experience with Twitter. He has popular blog about arts and culture. So, he started adding entries about the latest posts and comments submitted to his blog. Surprisingly, a lot of users started following his blog Twitter entries. This made me wonder if there is enough interest on the part of the PHPClasses site community to follow the latest activities of the users on the site. T...
