Big List of Naughty Strings

This might be interesting to some people for testing purposes. You all heard stories how certain input caused certain systems to crash. Here is someone who collected lots of these strings. Big List of Naughty Strings https://github.com/minimaxir/big-list-of-naughty-strings Luckily, Pharo can at least read them all in, without problems, as far as I can see.

Re: [Pharo-users] selectAllSortBy: usage

by Sabine Manaa

Hi Asbath, 1.) the code you have sent looks like there is a blank between # and date_actu. There should be no blank. 2.) You use the method selectAllSortBy: and not sortBy: I tried your code with my classes (with mongodb) and works like this: RKAPerson selectAllSortBy: {#date_actu-> 1. #heure_actu-> 1} asDictionary. This works for me. I hope this helps.

You should be able to call super super, as high up as you need to go. At least you can in VA Smalltalk.
