Did he not use a anti virus SW, i.e. a guard at the network port preventing viruses to come in? Or is this virus so new that a up to date i.e. Avira can not detect it? In which case I would jointly work with i.e. Avira. :)

Anything about modelling your app first? i.e. MVC (Model View Controller) paradigm. and there are others. Generally speaking: if you master that your view can get changed without touching the other two layers, then you profed already to be a professional. And nobody will say: "it's an old apps". because most do not understand or are able to valuate just the MVC paradigm. Also such things in mind makes chosing the language (dialect) more unimportant. Knowing your architecture of your apps helps you in many situation to prevent fatal errors or choose the proper i.e. IDE. my 2 cents. Josef

Maybe http://en.wikipedia.org/wiki/LISP[^]is what ALL here, discussing LISP should read to gain a comon understaning ground AND understand LISP in the larg. i.e Autocad as a CAD systems was able to use LISP, and I (even as a Autocad novice) was able to code new CAD parameterised drawing elements. Not so bad for me 20 years ago. Josef
