Just made this image, I thought it would be fun to share :3 (Yes there are a few memory leaks there due to no SysFreeString to match SysAllocString, but regardless... http://i.imgur.com/Fz36SHU.png COM to Microsoft Windows seems to be like Smalltalk to Smalltalk Runtime, with Object Browser being the Windows Registry. -- View this message in context: http://forum.world.st/Intro-to-Microsoft-COM-for-Smalltalkers-tp4917738.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I am not very fond of event loops in general, because they imply "many inputs, one output" (process all pending events, then update screen). For Morphic this is fine, because it displays on one screen, refreshing at/around its frequency. But there might be other screens, or network-output, file-output, which have different refresh frequencies. Then you would want to process input events as they trigger rather than storing them in a queue, such that whichever output destination sees the most up-to-date state of the program. Javascript has this cool function, requestAnimationFrame, which sets a one-time callback right before the next redraw. In essence it is an output event, allowing some form of reactive programming (no loop, only callbacks on input and output). In Pharo we have InputEventFetcher>>registerHandler: which is great for getting input callbacks, but nothing for output :/ WorldState>>addDeferredUIMessage: is probably a closest match, yet it is bound to Morphic, preventing experiments on UI/video games. Any alternatives?

Iceberg and git workflow
by Holger Freyther Oct. 3, 2016

Oct. 3, 2016

Hi, I am a heavy git user with languages like C, C++, Python, Ruby and even GNU Smalltalk and I hope iceberg will bring the same powerful experience to Pharo. Last Friday I started to add a bigger refactoring for a new feature to my software and didn't finish. Sadly today an issue in the code was found and I would like to fix this before fixing my code. I use this as opportunity to ask if Iceberg has some answers for that. With a non-Pharo project I would do: a.) If current HEAD is same as origin/master $ git stash (stash away my not finished changes) $ vi code.c fix.. $ git commit -a -c "subject long explanation of fix reference to bug" $ git stash apply (and go back to working on my feature) b.) E.g. if I finished n-commits but I am not fully done # store my work $ git commit -a -m "Work In Progress hack.." $ git checkout -b new-feature-branch # go back to master $ git checkout master $ git reset --hard origin/master (to restore) # work on the fix $ vi code.c fix.. $ git commit -a -c "fix..." # go back and continue on my fix $ git checkout new-feature-branch $ git rebase origin/master $ git reset HEAD^1 .. continue to work

Hi all, Iâve just seen that the unlimited offer that Amazon proposes for its drive is now available in France. !! Itâs 70â¬/year so quite cheapâ¦ Do people know if there are pharo packages to uses its RESTful API ? https://developer.amazon.com/public/apis/experience/cloud-drive/content/res… TIA (Iâll investigate deeper shortly), CÃ©drik
