isIsogram | i | i := 0. self asLowercase do: [ :char | | val | val := (char asInteger - 96). (val between: 1 and: 26) ifFalse: [ ^ false ]. (i bitAt: val ) == 1 ifTrue: [ ^ false ]. i bitAt: val put: 1 ]. ^ true An interesting observation here is that if #asLowercase is moved to each character instead âval := (char asLowercase asInteger - 96).â Then it leads to a 4-5x performance loss .

Yes I did that one too and I was surprised because it was as slow as the bag implementation. Anyone tried replacing the dictionary with an array of 26 booleans and indexing based on ascii, or even a SmallInteger and bit shifting?

Hi Siemen, Yes I was referring to the idea of including them in the player or linked the st files just like you do with the companions pdf and the videos. Really good work in progress.

hi Stef, Something like what Jannik was working on? I am also interested.

Hi peter I do not know but I would love that it would work. I should find some time to do a new pass on pillar.

Graph library in Pharo

by stepharo

Hi I'm looking for a graph library based on a matrix. I remember that I saw one but long time ago. Else if you know a pointer that explains how to implement it, I would like to ask this to potential topics. Stef
