Hi Fabien and welcome, you just discovered this phenomenon: http://en.wikipedia.org/wiki/Birthday_problem and you can be proud having discovered it by yourself!

In sets there can be only Unique nummers. So random produced a few of the same numbers. They get excluded from the set.

Hi Fabian, Welcome on board ;-) Set: I represent a set of objects without duplicates. so if you have the same number multiple times, it cannot be added more than once in the Set. replace Set by Bag (I represent an unordered collection of possibly duplicate elements.) and the size will always be 10.

A question about sets

by Fabian Boucsein

Hi there, i am new to Smalltalk and Pharo and today, while trying out some examples, i observed an somewhat strange behaviour. I used this snippet from the pharo.org website: | numbers | numbers := Set new. 10 timesRepeat: [ numbers add: 100 atRandom ]. numbers explore. Using Pharo 3.0 on my Laptop with Manjaro Linux 32bit and copy pasting the snippet above into the workspace i get sometimes a set with 10 values, sometimes with 9 values and once a set with just 8 values. Using this snippet, just to test the timesRepeat message: 10 timesRepeat: [ Transcript show: (100 atRandom); cr. ]. i always get 10 values. Is the behaviour with the first snippet correct? Giving sometimes 10 or 9 or even 8 values. Or is it a bug? I would expect to always get 10 values in my set. By the way i am totally excited about your cool programming environment. Keep on the good work. I justed started to explore it and can say it is awesome to work with. Kind regards, Fabian

ExternalWindowsOSProcess >>defaultShellPath "Default shell to run"\ | path | path := 'C:\Windows\System32\cmd.exe'. (OSProcess fileExists: path) ifTrue: [^ path] ifFalse: [self notify: path, ' not found'] but then whatever passed to an expected unix shell might not be suitable for the windows shell. Alternatively maybe Cygwin needs to be installed and used ? HTH, ben
