> rejecting an effort on documentation, whether its something that satisfy high standards or not, is something that the Pharo community cannot afford IMHO this is the exception to that obvious rule. OOP in particular is misunderstood by almost everyone. If we as Smalltalkers describe it from a forensic CS perspective that sounds to me like C++, I believe it is better that we say nothing on the subject. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Some-new-book-chapters-tp4815809p4815888.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Some new book chapters :)

by kilon alios

"It does not emphasize the key features of OOP - message sending and late binding - or the tremendous benefits." I am glad it does not , because if it did , it would be not a Introductory chapter to OOP. "This is an important topic that should be written about by a master OOP practitioner." Good luck, are you willing to wait another 5 years ? Because newcomers to Pharo with no clue to OOP finding fragmented information around the book about classes and objects, dont think will wait that long. I doubt if they last even a day. On the subject of message passing there is dedicate chapter for it in Chapter 4 and its also explained in Chapter 5. Late binding again its an advanced subject that will need its own chapter. For now my focus is making sure the reader understand the very basics of OOP. Without such basic knowledge is pointless to talk about advanced OOP features in Pharo. One can easily write a book on OOP with Pharo to explain the full potential, but since there are very few people contributing to documentation it comes down to the fact that every single contribution counts and the fact that UPBE must have an Introduction to OOP 5 years ago. Furthermore, if people are so willing to help out, the repo is open to every potential contributor, you can edit the chapter or even erase and replace it with your own if you believe you are up to the task. Until a better alternative comes up , the work will go on. By the way I am supervising the chapter , even though the student writes it, I will be editing and improving it along the way and as it is , is very far from finished. It will be included to the book as a pull request when its finished. My personal opinion , rejecting an effort on documentation, whether its something that satisfy high standards or not, is something that the Pharo community cannot afford with the serious problem in the lack of documentation. Its an area that Pharo can use any help it can get.

kilon.alios wrote > there is also one incoming for UPBE , an intro to OOP. I read this. It is a great student exercise, but IMHO it should not be considered for integration. It does not emphasize the key features of OOP - message sending and late binding - or the tremendous benefits. This is an important topic that should be written about by a master OOP practitioner. New users would be better off contributing to nuts and bolts - do this, then do that - sort or things, or finding parts that are unclear from their perspective. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Some-new-book-chapters-tp4815809p4815875.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

It would be very good to have another Glorp solution with a pure Smalltalk implemented DB driver, like the PostgresV2 one. IMHO this is way less error prone than the whole library/driver/.. mess on all these different platform. Sven

Re: [Pharo-users] MySQL framework for Pharo to analyze futures and options.

by volkert

I have similar plans and also want to use MySQL under Windows. Olivier points me to ODBC connector (http://smalltalkhub.com/#!/~PharoExtras/ODBC <http://smalltalkhub.com/#%21/%7EPharoExtras/ODBC>). Merwan points me to a MySQL driver (http://smalltalkhub.com/#!/~DBXTalk/MysqlDriver) Anyway: Can someone tell me, if DBXtalk is the way to go?
