The installation of Joomla! is a matter of five minutes. If you have installed it before, you can do it in two minutes. In order to be able to even start the installation, your development environment must include a web server that supports PHP and a database that is supported by Joomla!. Joomla! is one piece of the puzzle in this so-called Client-Server System. This topic is very complex, since there is an unmanageable number of providers and an even more unmanageable combination of installed Apache, PHP, and MySQL versions and Webspace administration tools such as Visas and Plesk.
In this article by Hagen Graf, we focus on the following points:
- A PHP safe mode, possibly activated in the php.ini
- Prohibited conversion of URLs with Apache because of the non-activation of the so called rewrite engine
- Directory rights in Linux that are set differently than in Windows
In the first part of this article we concentrated on two aspects Problem and Design. We started with the Problem, that is, defining what we need to implement the Friends concept, finding and inviting friends to join our network and developing an alert system. We then moved to Design wherein we actually finalized the requirements. And finally we began with the Solution, that is, actually implementing the features. In this part of the article by Andrew Siemer, we will continue with the solution part.Read ASP.NET Social Networks—Making Friends (Part 2) in full
Most web applications have rather simple error handling strategy. When an error occurs, the script terminates and an error page is presented. The error should be logged in the error log, and the developers or maintainers should check the logs periodically. In this article by Dennis Popel, we will look through the most common sources of errors in database-driven web applications.
- Server software failure or overload such as the famous "too many connections" error
- Inappropriate configuration of the application, which may happen when we use an incorrect connection string, a rather common mistake when an application is moved from one host to another.
All web applications and web servers have security vulnerabilities and there is every chance that our website will be compromised. Most web hosts have their own backup procedures in place, but it is not uncommon for a web host to become victim to an attack, and have problems with a small percentage of its customer backups. Because of this it is very important that we keep backups of our website. In this article by Michael Peacock, we will see how to backup our website and restore it back gain from our backup.Read Backing Up and Restoring TYPO3 Websites in full
