There is a mail Niall send me after I asked him for documentation Good luck ;) Merwan -------- Forwarded Message -------- Subject: Re: Glorp Documentation Date: Sun, 8 Feb 2015 18:18:13 +0000 From: Niall Ross (Cincom) <nross(a)cincom.com> Organization: Cincom To: Merwan Ouddane <merwanouddane(a)gmail.com> Dear Merwan, > I just wanted to know where can I find the glorp documentation you are > talking about here: > http://www.cincomsmalltalk.com/publicRepository/Glorp%28Bundle%29.html If you have a version of VisualWorks (or ObjectStudio) installed, then doc/GlorpGuide.pdf and preview/glorp/GlorpUserGuide0.3.pdf are paths from the root of installation. If you do not already have a version, you can download the Personal User Licence version and install it for free for non-commercial use, from http://www.cincomsmalltalk.com/ navigating from the PRODUCTS menu. Be aware the GlorpUserGuide0.3.pdf was never completed and is now very old, using some out-of-date protocol, etc. The GlorpGuide.pdf is much newer. You can also look at http://esug.org/data/ESUG2014/1%20monday/1400-1500-Glorp/GlorpTutorialGuide… which are the slides of a tutorial on Glorp that I gave at ESUG last year.

Hi, the most current documentation of (the most current) Glorp ships with VisualWorks. So your best bet is downloading their PUL product. The two tutorials mentioned by Cameron are not too outdated yet to be useless, but The DescriptorSystem has learned quite a few tricks since the time those were written. You need to ask your favorite search engine where to find them. I don't know of an official, still current place. Some other sprinkles of information can be found in several slide decks by Niall from ESUG 2013 and 2014. Very helpful once you've taken the first hurdle. I think, however, you can forget about Glorp.org as a source of information. It is painfully unmaintained at least it was when I last took a look. Sorry if I sound destructive. I use Glorp daily and like it very much. Niall and Instantiations are helpful in bug fixes and stuff it, but they sure cannot help in learning the basics.

MySQL framework for Pharo to analyze futures and options.
by nacho March 30, 2015

March 30, 2015

Hi folks! I'm using MySQL to hold some data on commodities prices for futures valuation and want to - of course - use Smalltalk as a front-end. Which framework would you recommend? This is a good opportunity for me to push Pharo in the company I work for. I want to leverage after that on Roassal and other visualization tools. But the data is already in a SQL database. Thanks in advance Nacho ----- Nacho Smalltalker apprentice.

Introduction to OOP for UPBE was: Some new book chapters :)
by kilon alios March 29, 2015

March 29, 2015

I would like the opinion of the community on this. I have discussed the addition of an introduction to OOP back when I was very actively contributing to UPBE and the response I got was very positive. The plan was similar to what I mentioned, just bare basics , making sure that the reader understand the very basic fundamental concepts of OO, like classes, inheritance, instances, class and instance variables, class and instance methods etc. Essentially a chapter similar to my video tutorials but going a bit deepers with more detailed example still keeping it simple , clear and understandable even for non coders. I want to know whether such chapter would be included because I dont like to waste my time or the precious time of the student that has taken the task on her shoulders. "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." Personally I dont care if people misunderstand OOP , I only care about getting my code to work the way I want it. So far I had no problem doing that even though I code using very simple concept some of them may come even back when I was coding in C++. I also dont share the sense of wonder that some of you may share about how Smalltalk is doing OO, coming from python does not seem such a big deal for me. For example message passing suppose to be this super powerful feature , that diffirentiate from method calls in the essence that the user does not need to know the internals of the class. But I have not seen a class that take advantage of this feature inside pharo. In every single case if I had exchanged the message passing with method calls I would not have even noticed the difference. In every case I have studied each message corresponds to a method with exactly the same name. I am sure maybe one day will come handly , but I dont see why one needs to explain a feature that rarely someone will use understand how to code in a specific environment.

March 29, 2015

Hi everyone, I'm currently searching for a subject for a project to do during my first year of master. I want to do something that is linked to pharo. Following StÃ©phane Ducasse advises, I had a look in topics.pharo.org and I saw a subject that could interest me named "Deep learning". But there is no supervisor. Does anyone here have more informations about it? Regards, Julien

moose at the breathing code conference
by Tudor Girba March 28, 2015

March 28, 2015

Hi, My talk on Moose was accepted at the Breathing Code conference to be held on May 5 in Frankfurt: http://breathing-code.de/program.html#data-analysis-moose It's an interesting setup that fits both Pharo and Moose like a glove. However, this being the first edition of the conference, the organizers are a bit in trouble as there are not enough registrations. They need to reach 35 participants until April 1, and they urge people to spread the word. Now, I kindly ask you to spread the word the best you can about this conference. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

I recommend the Glorp interface. Sensible API, clean, it works. Nacho, what is your data source? You have the data in MySQL, but do you need to put it in MySQL? If not, I would encourage you to use an object-model persistence/DB approach. -Cam On Sat, Mar 28, 2015 at 2:19 PM, Joachim Tuchel <jtuchel(a)objektfabrik.de> wrote: > Nacho, > > I guess Glorp can be regarded as gold standard for o/r mapping in > Smalltalk.
