[Pharo-project] Howto measure memory footprints of functions/objects/libraries in Pharo?

by Guido Stepken

E.g.: Three different solutions for a Euler problem: (1 to: 999) inject: 0 into: [:sum :i | (i \\ 3 = 0) | (i \\ 5 = 0) ifTrue: [sum + i] ifFalse: [sum]] (1 to: 999) detectSum: [:i | (i \\ 3 = 0) | (i \\ 5 = 0) ifTrue: [i] ifFalse: [0]] (1 to: 999) detectSum: [:i | i * (#(0 0 1 0 1 1 0 0 1 1 0 1 0 0 1) atWrap: i)] How do i measure the exact memory footprint of each solution? Pharo claims having reduced memory footprint at many places. Can that be proofed, e.g. with one comparable demo app, once run in old squeak, once in Pharo 1.1/1.2? And no, MessageTally spyOn: does not do right! Tnx in advance, Guido Stepken

Hello, I want to be able to take some screenshots of the Pharo menus, and would like to have a plain white background instead of the 'Pharo' logo.Â I've tried setting : System->Settings->Appearance->Desktop->color to white, but it didn't have the effect I wanted. Any ideas? Many thanks in advance, Sheridan

it would be nice if emails can also be specified by a prefix. For example [ISSUE] Even if most mail client can filter by different ways, having a preffix is nice too. is that possible?
