Periodic long GC's when just coding in newer Pharo 7's?
by Tim Mackinnon Sept. 8, 2018

Sept. 8, 2018

I thought I would mention this as its something Iâve only just started to noticeâ¦ when doing some brief coding sessions (as in, each day I unsuspend my laptop and code for 30-40 minutes - to write some missing tests) - I have started to notice I get a spinning beach ball in Pharo for 15+ seconds and then it recovers. Itâs usually once each day, and it does recover. It feels like its deciding to do a GC - but Iâm not sure how to tell. It could be nothing - but its not something Iâve noticed in Pharo 6.1 and seems unique to Pharo 7 (which Iâve started to try using more recently). Its just happened now in build 1167 64bit on OSX (I believe I have the newer vm - as I had to re-download them for pharo-launcher). Tim

PetitParser map
by Hartmut Krasemann Sept. 7, 2018

Sept. 7, 2018

Hi, I work a lot with PetitParser in Pharo 5 and fail to display the parser map in PPBrowser. The config is Pharo 5Â with - PetitParser (JanKurs.278) and - Roassal2 (AlexandreBergel.1638) as installed from the Pharo Project Catalog A first problem, occuring on selection of a Parser in PPBrowser was fixed easily: GLMCompositePresentation>>smalltalkCodeÂ Â -> >>pharoMethod But I am lost to fix the second problem on displaying the parser map in PPBRowser. PPParserBrowser>>mapInÂ Â tries to execute RTMondrianViewBuilder new but RTMondrianViewBuilder does not exist What can I do there? -- signatur Hartmut Krasemann KÃ¶nigsberger Str. 41 c D 22869 Schenefeld Tel. 040.8307097 Mobil 0171.6451283 Krasemann(a)acm.org

A nice example of how Pharo can be used for domain-specific modeling and simulation. Short session from one of our projects at Rochelle: https://www.youtube.com/watch?v=Z7wJNhAIaVQ Some additional info here: https://goo.gl/jS4NjB Currently investigating how to incorporate the new Bloc based widgets of @feenkcom into the workflow.

Configuring iceberg on Windows
by Andrei Stebakov Sept. 7, 2018

Sept. 7, 2018

I followed the tutorial and provided IceCredentialProvider with ssh settings, also put the same settings in Settings-Tools-Software Configuration Management. It seems not to have any effect since when I try to create a repo using SSH it gives the error "Failed to connect to github.com". I need to get past that error since I get it even when I install Moose via Metacello. Do I need to add ssh-agent as well? If yes, why do we need to provide public/private key paths with IceCredentialProvider?

adding instance variables (data) to the Object class
by Petr Fischer Sept. 6, 2018

Sept. 6, 2018

Hello! Weird question: why I can't add instance variables to the Object class (for example "oid" or something else)? Is it due to some internal (and different) VM "class layouts"? Or - can I inject my own information to all existing objects (any class)? Thanks! pf

Secure socket timeouts on Windows
by Andrei Stebakov Sept. 5, 2018

Sept. 5, 2018

This issue has been bugging me for a while now, but I hesitated to post it since I can't explain what's going on. Every time I do any operation in Pharo related to secure socket connection I have strange socket timeout even though I can connect to the URL using web browser. This time I was trying to install latest pharo 7.0 via pharo installer and I got ZdcSecureSocketStream waitForDataFor: hang over trying to download https://files.pharo.org/get-files/70/pharo-win-stable.zip I can paste that link in Chrome and it can download it for me no problem also I can download it using curl. This issue only happens to me at work, when I do the same from home I don't see this issue. Anyway, I am at a loss here and wonder how can I debug and fix this issue. Wondering if something like that happened for you guys.

Smalltalk Security Landscape - survey for ESUG 2018
by Jerry Kott Sept. 4, 2018

Sept. 4, 2018

Dear Smalltalkers and friends, I am planning to have a presentation titled âSmalltalk Security Landscapeâ at this yearâs ESUG conference. In my presentation I hope to increase cybersecurity awareness within the Smalltalk community and help shape the evolution of the language and its ecosystem. I have put together a survey to help me research the topic. I ask for your kind help to get a picture of where Smalltalk stands in the area of cybersecurity. The survey is completely anonymous, and should take less than 15 minutes to complete. I appreciate your time and participation. If you are in a management role, I would like your help by forwarding this to your team members to help reach the broad Smalltalk community. Here is a link: https://www.surveymonkey.com/r/esug2018 <https://www.surveymonkey.com/r/esug2018> Thank you for your help, and hope to see you in Cagliari!
