happy lessons from recent talks
by Tudor Girba Jan. 12, 2016

Jan. 12, 2016

Hi, I just wanted to share with you a bit of a different perspective on what we do around here. Over the past half a year I gave several talks to some 1k technical people at industrial events like ArchConf, NDC Oslo and several others. The tour will continue this year at OOP, ArchConf and a couple of other places. These are places where people talk about mainstream techniques & technologies (like Java, JS, C#). For example, ArchConf is a premier software architecture conference in the US. During these sessions, people get to experience Moose and Pharo through live demos. I use these demos as examples of how humane assessment (building your own analysis tools) can boost engineering decisions making in practice. I consistently receive the feedback that the live programming possibilities from Pharo/Moose are impressive. But, more recently, there is something else worthy of being noted. If in previous years, nobody heard about what we do, this year I started to get consistently a couple of persons in the room that have heard something about Pharo/Moose before the presentation. This is huge. While a couple might not sound like much, you should remember that information (especially in this technical space) has the capability of spreading exponentially. What we have done over the past years starts to show results. We have to keep it up. Happy New Year!

[Survey] Forking Operating System Proces in Pharo
by Mariano Martinez Peck Jan. 12, 2016

Jan. 12, 2016

Dear all, As I mentioned in the thread "Pharo Consortium Sponsored Development Effort" [1] I built a survey about Forking Operating System Processes in Pharo. The idea of the survey is simple: I want to understand what people needs the most, which features would be useful, which ones would not, what is missing, what is wrong, etc etc etc. As always, since we have limited resources, we should optimize them as much as possible. I count with you so that we can make a roadmap together on this project. Please, feel free to forward this survey anywhere where there could be an interest. https://www.surveymonkey.com/r/DHR22TL Best regards, [1] http://forum.world.st/ANN-Pharo-Consortium-Sponsored-Development-Effort-td4… -- Mariano http://marianopeck.wordpress.com

Test Runner: "Run Coverage" fails or hangs when multithreading is used in test.
by Skip Lentz Jan. 12, 2016

Jan. 12, 2016

Hi, When I want to run the coverage of for example Zincâs Client and Server tests, it will either hang (in the case of Zincâs test cases) or fail because the coverage uses BlockClosure>>valueUnpreemptively for running the tests. The relevant method is TestRunner>>collectCoverageFor:. So when a test is run, it is not able to be preempted by another process, like for example a local server which is needed to run the actual test in Zincâs case. When I use BlockClosure>>valueUninterruptably it works. Can someone tell me if it is wrong to use that instead? Is valueUnpreemptively necessary in this case, and if so, why? To reproduce: Load fresh image, select Zinc's ZnClientTests and ZnServerTests, click on âRun Coverageâ -> hanging image. Thanks, Skip

Pharo50 spur works on CentOS?
by Blondeau Vincent Jan. 12, 2016

Jan. 12, 2016

Hello, I just wanted to run a latest Pharo image on a CentOS server to run a Zinc server. So I did: curl get.pharo.org/50+vm | bash ./pharo Pharo.image eval "1+1" evals to 2 But, ./pharo Pharo.image --no-quit eval "ZnServer startOn: 8080." returns: ioLoadModule(/root/Pharo/pharo-vm/libFT2Plugin.so): libfreetype.so.6: cannot open shared object file: No such file or directory So the server is not launched... What are the libs that should be installed on the machine? Should I take another VM? BTW, why a headless image needs a freetype lib?

Atomic commits
by Nicolas Cellier Jan. 12, 2016

Jan. 12, 2016

Hi, I wish the commits were much more atomic than they currently are... With current practice, reviewing the changes is near to impossible: - it requires far too much concentration - it's just impossible through github web interface For example, I did wander if the structure fields were correclty aligned in: https://github.com/pharo-project/pharo-core/blame/5986a695fb28834247a90dbf8… because I see no code for aligning the offsets... But I cannot even navigate in the history... If I do so, https://github.com/pharo-project/pharo-core/commit/dfd4f3ae0f0b0af7766c1405… the page tells me "Sorry, we could not display the entire diff because too many files (2,121) changed" and I couldn't find a way of displaying the portion of interest. I thus loose the ability to deposit a comment. I can still open a fresh Pharo image and browse and review the whole code snapshot there. Or I can navigate more easily in history with git tools. But if I wanted a lightweight review thru web, focusing on the diffs and navigating a bit in history without replicating the repository, I can't. While ranting, it's nice to have the commits performed by a jenkins server, but how do we track the authors of original modifications? In a normal git based development, there would be feature branches integrated/merged in trunk/master by whatever process. But in current process i fail to capture such information... This gives a taste of under-powered use of the tools, and I wander if being visible in these conditions is a good thing: we don't expose the best practices.

Understanding Spotter?
by stepharo Jan. 12, 2016

Jan. 12, 2016

Hi Is there a help a student or idiot like me can read about how to find information with Spotter? For example We with luc wanted to find all the senders of variableSubclass: we tried # #senders and more... but gave up. Yesterday I wanted to find all the user of <menu> May be I missed an obvious help that will enlighten me? I hope. Now without such help how can we expect students or users to discover the way we should use the tools? We were planning to do a video to explain Spotter but I'm slowly thinking to discard this video because we do not know. Stef
