Validating allowed characters or validating disallowed characters

- by Tom

I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

Sending keyboard commands to Ubuntu through Python. Remote for my Blackberry

- by Rudi Strydom

I am trying to build a remote control application to control media on my Ubuntu. Does anyone know a way in order to accomplish this. The media keys in particular. Thank you. EDIT 1: I have tried using XTE, but is seems python in truncating the input or there is a limit or something which means that you can't do Ctrl + Key key presses, which wont suit my needs. I also tried uinput, but alas you need to run it as root, which also will not quite my needs. Now I am looking at EVDEV which seems promicing, that is if I can get it working.
