Re: [Pharo-dev] R: from 2009's The "death" of Smalltalk to 2014's But Really, You Should Learn Smalltalk

by J.F. Rick

Hi Sebastian, Noel is actually my academic older brother (i.e., we had the same doctoral advisor). Noel's introduction is nice but it is to people who know how to program (specifically, Ruby programmers). That's useful. The Pharo books and YouTube videos do this very well. But, you also need to provide a way in for people who are learning to program. One thing you could do is provide a book that could be used at a university to teach object-oriented programming.

Object logging instead of String logging is the way to go. SystemLogger, Beacon, Zinc's ZnLogEvent are examples. Search the mailing list for past discussions. > TIA > -- > Regards, > > Alain > >

[ANN] Visual Memory profiler

by Alexandre Bergel

Dear Friends and Colleagues, We are happy to announce Memory Profiler, a new profiler for Pharo. This profiler gives a nice output that indicates the memory consumption along the method call graph. Consider the following piece of code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= (MSP profile: [ Object browse ] onPackagesMatching: 'Nautilus*' ) inspect -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Consider that MSP uses instrumentation, therefore long execution may take really long. The code above takes about 19 seconds on my iMac. It opens a visualization that indicates some interesting fact about memory consumption. For example, the expression âObject browseâ consumes 14 851 kb with instances of the class Point. More than 1M of points are created. Here is the blueprint obtained: https://dl.dropboxusercontent.com/u/31543901/TMP/memoryBlueprintExample.html A description of the visualization is available here: https://dl.dropboxusercontent.com/u/31543901/MyPapers/Infa15a-MemoryProfili… You need to load Spy from the Configuration Browser. Else the following incantation should work: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Gofer it smalltalkhubUser: 'ObjectProfile' project: 'S2py'; configurationOf: 'Spy'; loadDevelopment. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Cheers, Alejandro & Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

There are lots of things. But Log4s works and yeah, it is similar to Log4j in concept.

What Logging framework for Pharo

by Alain Rastoul

hi all, Googling a bit for a logging framework in Pharo, I found sl4j, which sounds familiar to me. http://ss3.gemstone.com/ss/Log4s.html/Wiki I suppose the API is the same as the java package, as claimed by the project page. I wonder if anybody is using it , or has tried it and have an advice on that package ? (I saw there was no test and no comments ... :( ) I think it could be great for Pharo to have a standard package like that, a logging facility is mandatory for most -if not all- applications Any advice or pointers ? TIA -- Regards, Alain
