Mentor - How do I know when the right time is to launch my start-up? This article first appeared January 19th, 2012. I want 2012 to (finally) be the year that I quit my job and start-up. But I’m a bit scared of making the leap. How do I know when the right time is to launch my start-up? Should I just get on with it? Leaving the shelter of having a boss requires a combination of good preparation before you make that leap, as well as a disciplined capacity to stick to your plans during the transition to being the only person to blame (or praise). When you have answered these six questions you will be best placed to make that leap: Have you sat down with your accountant and worked out whether you should operate as a contractor during the transition to your own business operations?

Avoid the Original MySQL Extension, Part 1 Experienced developers eschew the original MySQL extension because of its abandoned status in PHP. Nascent web developers, however, may be completely oblivious to its dormant past and dying future. Introductory tutorials for connecting to MySQL from PHP are certainly abundant, as is evident from a simple “php and mysql tutorial” Google search. It’s just unfortunate that many of them teach only how to use the original MySQL extension. This has channelled new developers who would like to learn how to interact with their database to only one of three potential extensions, giving them a skill that will soon become useless in an upcoming major version of PHP. In turn, this has increased the amount of people who rely upon the extension and will, in some cases, use it as their one-and-only database access method. What’s Wrong with the MySQL Extension? Aside from the fact that it’s currently in the process of being deprecated, there may seem to be nothing wrong with the original MySQL extension.
