They are written in a formal language that looks hard to understand on first glance but follows strict rules. Most users associated regular expressions with programming languages and while this is surely a dominant area regular expressions are supported in text editors and other tools. One of the most popular is probably grep in the Linux operating system.

The Regex Coach is an excellent software program to learn regular expressions as it displays realtime results in its interface. The interface itself is divided into two display panes that contain the regular expression and the target strings. Below are tabs and buttons that provide additional functionality.

A user who wants to test a regular expression would enter it in the first column and add a target string in the second. The program automatically highlights the area of the target string that is matched by the regular expression. Any modification to the regular expression will automatically be visualized in the target string pane.

Invalid entries are displayed automatically as a status message. The program will for instance notify the user if a bracket has not been closed which would make the expression invalid.

The Regex Coach is a learning by doing aid for learning or verifying regular expressions. There is still need for a documentation on regular expressions like this one.

I have been using the service twice in the last two months and liked it that much that I thought a review would be nice to spread the word. Webmasters can post -mostly – IT related projects on Get a Freelancer and freelancers will respond to that project. Those responses will always contain the amount of money that they would charge for completing the project as well as other information.

The project creator can then pick one of the freelancers who responded with an offer. It is possible to use a private messaging system to communicate on site to get the details right before a deal is closed. The website offers an Escrow service that will withhold the money until the project has been finished.

Adding a new project costs $5 which are subtracted from the money that is being paid to the freelancer if one is selected to finish the project. I think that this website offers some nice opportunities for freelancers as well. Just take a look at the average bid amount for certain categories to know what I mean. The price range for most projects lies between $100 and $1000.

While the website concentrates on brokering IT deals it does have several other categories that are related in a way or another. You can find and post offers for Accounting, Translations, Photography, Legal Advice or Copywriting on the website as well.

I like to post projects there because I know that my money is safe until the freelancer completes the product to my satisfaction. A rating system that has been implemented makes it easy to analyse a freelancer by previous works that he has done on the site.

I’m not using the website as a tool to earn money but I guess you could be highly successful if you are an expert in any of the categories that are offered on the website.

You find introductions to the languages as well as topics that are best suitable for advanced users. If you are currently learning a programming language or always had the desire to learn one but never wanted to pay lots of money for books this site is for you.
