Hi, I donât have access to jenkins config, but it looks like the Plot Plugin[1] is not latest version. Can someone please update because they added support for matrix jobs. Uko [1] https://wiki.jenkins-ci.org/display/JENKINS/Plot+Plugin

Linux using the Jessie repositories. Crunchbang is a Debian distribution with only a number of preconfigured items, such as OpenBox, Tint2, etc. to give a nice out of the box Debian experience. The Ubuntu PPAs do not work well or could cause problems for Debian systems. From the pharo-vm GitHub page I downloaded and modified this script to work on my system. It should work on most any 64bit Debian Jessie/Testing and probably Sid/Unstable systems. I am not sure about Wheezy. https://github.com/pharo-project/pharo-vm/blob/master/scripts/setup-ubuntu.… Download the above and edit. Or copy the below into a file and save. I called mine setup-pharo.sh. Hope this helps.

Re: [Pharo-dev] Aconcagua Hashing Bug?

by Maximiliano Taborda

In few words, one measure is equal to another when their internal collaborators are equals between each other. And the hash of two measures are equals when the hash of their collaborators are equals too. Then, some examples "#=" (1/2) = 0.5 "this evaluate to true" (1/2) ~= 0.5 "this evaluate to false" "#hash" (1/2) hash = 0.5 hash "this evaluate to true" (1/2) hash ~= 0.5 hash "this evaluate to false" Seeing the same with aconcagua | teaspoons aHalfTeaspoon anotherHalfTeaspoon | teaspoons := BaseUnit named: 'teaspoons'. aHalfTeaspoon := Measure amount: 1/2 unit: teaspoons. anotherHalfTeaspoon := Measure amount: 0.5 unit: teaspoons. "#=" aHalfTeaspoon = anotherHalfTeaspoon "this evaluate to true" aHalfTeaspoon ~= anotherHalfTeaspoon "this evaluate to false" aHalfTeaspoon unit = anotherHalfTeaspoon unit "this evaluate to true" aHalfTeaspoon unit ~= anotherHalfTeaspoon unit "this evaluate to false" aHalfTeaspoon amount = anotherHalfTeaspoon amount "this evaluate to true" aHalfTeaspoon amount ~= anotherHalfTeaspoon amount "this evaluate to false" "#hash" aHalfTeaspoon hash = anotherHalfTeaspoon hash "this evaluate to true" aHalfTeaspoon hash ~= anotherHalfTeaspoon hash "this evaluate to false" aHalfTeaspoon unit hash = anotherHalfTeaspoon unit hash "this evaluate to true" aHalfTeaspoon unit hash ~= anotherHalfTeaspoon unit hash "this evaluate to false" aHalfTeaspoon amount hash = anotherHalfTeaspoon amount hash "this evaluate to true" aHalfTeaspoon amount hash ~= anotherHalfTeaspoon amount hash "this evaluate to false" So, I don't see where is the bug.
