This difference is that in Smalltalk the exception handler is executed in the context of the exception, allowing the programmer to see the point of error and provide a value with which to /resume/ execution. In Java the exception is delivered in the context of the handler, discarding the execution state that caused the exception, only allowing the program to /restart/ the code that caused the exception, and making investigating the cause of the exception impossible in the current run.

CPU usage change on newer OS

by Norbert Hartl

I have a strange effect on my machines. I have a dedicated server and a lot of virtual instances using LXC. The last few days I migrated most projects of our projects from pharo2.0 to pharo3.0. And on the same time the images moved from an ubuntu 12.04. system to a ubuntu 14.04 system. Looking at the top command it appears the images/vms need noticable less CPU or better the tools report less. The monitored overall CPU usage also is much lesser than before. This is not proved by any measurement. Has anyone an idea why this could happen or appear differently? Norbert

Nice milton :) Nice to see it in Pharo :) Milton do you use it regularly to optimise your own code? Else pay attention that light grey is a pain to read on screen. So to me this is the first thing that would get in my way to use: reading text is key. Keep your great work.

Really beautiful! I will take a look as soon as possible at the code. This is definitely a candidate to be included in GT. In the meantime, please just do not use a Gary background to show gray data. Just use white.

Well... this is a really neat visualization to have as a developer tool. Thank you! Esteban A.

Inti in Pharo

by milton mamani

Hi all, I would like to show you the Inti, Inti is a cool visualization to compare and handle instances of MessageTally. This is just a demo, nothing in this mail is final. This image shows the Inti program in GTInspector [image: ImÃ¡genes integradas 1] The color mapping is explainning in http://www.humane-assessment.com/blog/?_k=W1xeAy75PKaNEd2G [image: ImÃ¡genes integradas 2] Purple nodes ares nodes that have the same class of the selected method. [image: ImÃ¡genes integradas 3] This is inti profiler in pharo, this allows your to compare 2 (or more) instances of MessageTally, and see the difference of this tallies. [image: ImÃ¡genes integradas 4] You can get this program executing the next piece of code: Gofer new smalltalkhubUser: 'azazael' project: 'inti'; package: 'ConfigurationOfInti'; load. (Smalltalk at: #ConfigurationOfInti) load. http://objectprofile.com/Inti.html Best regards, Milton
