Saving in Pharo

by Mohammad Al Houssami (Alumni)

Hello everyone, This is probably the stupidest question you might get but when you hit cmd + s when coding doesn't this save the image ? I've been working for 8 hours now and when I closed pharo I pressed YES for quite without saving because im stupid!!!! I lost all my work right ? :) I have to right click and save for the changes to be saved right ? :) Is there anyway to get them back or shall I forget about it ? Im so desperate Thanks Mohammad

Log of the retrospective analysis from Pharo 2.0

by StÃ©phane Ducasse

Hello happy pharoers Since Pharo2.0 will be released pretty soon, we led a retrospective analysis to learn and improve our process. Here are the notes taken by clement from the meeting led by esteban with all the team here. Pharo 2.0 Retrospective meeting by Esteban Lorenzo The Good BugTracker as Backlog Sprint / mini - sprint / pair programming Locking changes before release Community getting involved Web doc jenkins : the monkey, zeroconf script Smalltalkhub The Bad Trello We need a place to backlog what to do. We should use the FogBugz bug tracker Long development cycle (1 year), Focus problem : most things works but are not finished We should have a 1 to 2 months cycle with a part where we introduce new things and a part where we only fix bugs. At the end of each cycle, Pharo should be stable. Each cycle should have a retrospective meeting. We should pair program every friday afternoons on Pharo improvements. New failing test in Jenkins, Red builds on jenkins stayed forever We need a clear separation between pharo and pharo contribution both on smalltalk hub and Jenkins to have a clean green front end to show to end users In case of a red build, we need a quick meeting to pick someone to fix it. We need to fix the red builds on the friday' mandatory mini sprint Integrator bottleneck More intelligent monkey better tools (spec tool idea from Esteban where you just click accept and the slce is integrated) New features accepted only with tests and comments Only slices accepted no more change sets Pointless discussions on the mailing list Documentation : class comments, ... do not integrate undocumented features add code critics features in the monkey change the template of the class comment The Ugly 2 weeks lost : broken image during ESUG 2 weeks lost : beginning of the year : no VM working, jenkins couldnât test things. -> we will staged development. Communication failed : team and community For new features, send more mails to the Pharo or RMOD mailing list and less to the RMOD mailing list or private mails between few people Infrastructure VM : stability Stability : 1 VM release per Pharo release. 1 official Vm which is not just some VM from a build. Stability : VM not release if an acceptance list does not work with the VM. The acceptance list is for now all the Pharo core, seaside and Moose

GSOC Proposal: Smalltalkhub continuous integration service

by Esteban Lorenzano

Level: intermediate Possible mentor: Nicolas Petton Possible second mentor: Esteban Lorenzano Description: Continuous integration services are becoming a fundamental part of programming process, and tools for easy the execution of builds are emerging and being integrated directly into the version control systems (like travis and github). We propose to add this facilities to pharo flag version control service (smalltalkhub), to facilitate the adoption of continuous integration processes into our community. Technical Details: This project implies the extension of smalltalkhub and the configuration of building jobs into the pharo community public infrastructure (and explore the possibility of using travis itself). Benefits to the Student - Use a highly reflective dynamic language - Learn to develop a complex multi-module architecture with several communication pipes. - Learn about REST interfaces. - Learn about integration of different services developed in different technologies. - Learn web application development techniques. Benefits to the Community - have a platform for automate continuous integration processes - indirectly increase the quality level of the frameworks developed

Re: [Pharo-users] Unicode in Smalltalk

Ok it's just that I didnât understand the notation he used. Its clear now. I know about radix and bases and all this stuff but itâs the notation that got me confused. The whole thing was just changing the notations from base 16 to base 10. I tried it and it works.
