GSoC13: Google Summer of Code started, your ideas please!

by Janko MivÅ¡ek

Dear Smalltalkers, Time for your cool project ideas on this year Smalltalk GSoC! For now just express any idea you have here on the mailing list. Later we will together develop it to be in complete format together with two mentors needed. Deadline is end of Mart, so we have three weeks of time. To see how fully developed ideas look like please look at 2012 ones at: http://gsoc2012.esug.org/ideas. Note also that students yourselves can propose a GSoC project. So if you like to be a student on this year GSoC and have a nice idea, don't be shy and propose it here! The community will listen you and guide to the really nicely proposed project. Last year 6 student proposed projects were accepted and finished successfully! For the community, start looking around for students. Think about how to approach the universities near by you, do you know who to contact there, etc. We are namely preparing an application to this year Smalltalk Google Summer of Code under ESUG umbrella, as last year. If accepted, Google will pay few stipendiums to students on our Smalltalk projects. More on our special Smalltalk GSoC 2013 website: http://gsoc2013.esug.org I'm specially inviting mentors of all past GSoCs to rejoin the mentors mailing list, where we discuss all details about this year GSoC: http://groups.google.com/group/smalltalk-gsoc-mentors While students interested on GSoC please join a special Smalltalk GSoC mailing list for you: http://groups.google.com/group/smalltalk-gsoc-students Best regards Janko -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

Re: [Pharo-users] Breaking down BorderMorph

by Hilaire Fernandes

Hello irfankhan1, I don't think BorderedMorph will be helpfull, better you implement your own morph, with its own border logic and override drawOn: method. Moreoever you can have a sharp control of the extend area where borders drawing occur. Should be pretty easy.

It was close, but see what jan.struz says in his reply. The 'newDictionary' should be {'$set' -> newDictionary}. I hope I didn't steer you the wrong way.

'attr2' -> 'value2' } asDictionary.

Oops, when I looked back my code, I found that I had started the project using node.js. When I was doing the mongodb UPDATE, that was still being coded in node.js. (I grew frustrated with node.js, and moved back to the comfort of Seaside). Looking at the Mongo code in Pharo, I think you can achieve what you want by calling: MongoCollection>>update: origDictionary with: newDictionary Set up the 'origDictionary' to have key/value pairs for only the identifying key attributes - e.g. {'person-id' -> 'Johan'} Set up the 'newDictionary' to have key/value pairs for only the attributes whose values need to be updated. Warning - I've never tried this, but it looks like it should work.

Re: [Pharo-users] does MongoTalk implement modifier operators? e.g. $set

by Sabine KnÃ¶fel

I do currently not save big documents or pictures within the person but I will save things like the name of the view which was clicked each time the user changes to another view. I think saving the whole person data (address, bank data etc) would create much overhead. I also save travel data with receipts, vehicle trips etc. Changing the name of a trip should not lead to saving the whole trip with its vehicle and receipt data....So for me, using update operations would make much sense. And perhaps, later, documents could be added, too. Sorry, I added confusion, I meant: "What are the experiences of bigger projects using MongoTalk - do you always write the whole DOCUMENT? (and not collection)" Yanni, you wrote "I used the MongoDB connection directly, and wrote it to use the mongodb UPDATE operations (because that's how all the mongodb examples did it). " Yanni, I understand, that you have some code to perform UPDATE operations from Smalltalk? Could you please send me some examples?

My very small app was almost done, before I came across MongoTalk/Voyage. I used the MongoDB connection directly, and wrote it to use the mongodb UPDATE operations (because that's how all the mongodb examples did it). If I'd started with MongoTalk/Voyage, then I would probably just accept the re-writing of the whole document.
