Re: [Pharo-users] Recommended stable Pharo 5.0 VM for Linux users?

by Esteban Lorenzano

yes, at the end I did a different process. after cloning vm sources, now you do not need to generate themâ¦ just go to $ cd build.linuxWHATEVER/pharo.cog.spur/build $ ./mvm that will work and produce the official latest VM :) Esteban > On 12 Apr 2017, at 09:59, Luke Gorrie <luke(a)snabb.co> wrote: > > On 4 April 2017 at 12:16, Luke Gorrie <luke(a)snabb.co <mailto:luke@snabb.co>> wrote: > On 4 April 2017 at 12:01, Esteban Lorenzano <estebanlm(a)gmail.com <mailto:estebanlm@gmail.com>> wrote: > well, Iâm working on commit also generated sources as an amendâ¦ but you will need to wait a couple of days for that :) > > Sounds great, thanks in advance! > > Gentle ping on a Pharo VM unix source release that works with the 5.0 image :-) > >

why is adding instance variables so slow?

by Peter Uhnak

Hi, does anyone know why adding instance variables is so slow? I did some quick benchmarks (see below), resulting in more than order of magnitude speed difference between having it in the class definition and adding it later. In fact it is still much faster to delete the class and then recreate it with the instance variables in the d efinition. For four arguments it is till 8x faster to delete the class four times and recreate it then just add the variable. Unfortunately I cannot just trash the classes (they have methods and inheritance). So the question is: why is it so slow? can I somehow improve the performance? Thanks, Peter Benchmarks: [ cls := Object subclass: #Some1. cls removeFromSystem. ] bench. "'91 per second'" [ cls := Object subclass: #Some2 instanceVariableNames: 'variable'. cls removeFromSystem ] bench.

[ann] steering agile architecture video published by o'reilly

by Tudor Girba

Hi, I am happy to announce that OâReilly has published my Steering Agile Architecture video training: http://www.humane-assessment.com/blog/steering-agile-architecture-video-tra… This video is based on my work on humane assessment, and it features Moose prominently. It also shows Pharo, GT and Roassal (in the last part). The video is indeed paid and it is mainly targeted to people that have a Safari Books Online subscription. But, the interesting thing about it is that it opens Pharo and Moose to a new kind of an audience, OâReilly being the most prominent publishing company in the software area. Agile architecture is considered a prominent topic but the literature (until now) was rather loose at how to make it really work in practice. This course offers both a concrete approach based on humane assessment. As you might know, humane assessment centers around the idea of building tools cheaply as a way to figure the system out, and this is right now pretty much only practicable in Moose and Pharo. One thing that I ask people when I go to conferences, the last one being the Software Architecture Conference organized by OâReilly, is if they like working with legacy systems. They actively dislike it. Then I show them demos of how it can be like and then I ask them if they think these demos are cool. And I never encountered one that did not find it cool. So, in a way, we can now be quite confident in saying that we work on the single platform that makes working with an existing system cool. Not a small feat. So, if you do get the chance to look at these things, you might also get a concrete inspiration of how to leverage Pharo skills within companies that do not yet work with Pharo.
