[ANN] Mapless a small framework for storing objects in a key->data fashion with no friction
by Sebastian Sastre May 6, 2014

May 6, 2014

Mapless Mapless is a small framework for storing objects in a key->data fashion (i.e.: noSQL databases) without requiring any kind of object-data map. So far only MongoDB is supported. It can use Redis for reactivity (pub/sub) and cache. Motivation I wanted to persist objects with extremely low friction and extremely low maintenanceand great scaling and availability capabilities so Mapless is totally biased towards that. This framework is what I came up with after incorporating my experience withAggregate. There is no spoonâ¦ There is no object-relational impedanceâ¦ There is no instVarsâ¦ only persistence :D Code and instructions here: https://github.com/sebastianconcept/Mapless All MIT, enjoy sebastian o/

(eliot?, nicolas? ) It is easily fixable, I think. But I am not good at inline assembler. I'll open a mantis and fogbugz report. regards Nicolai

Usage of should: in tests
by Nicolas Cellier May 5, 2014

May 5, 2014

Hi, I see many usage of #should: in SciSmalltalk tests that could simply be turned into #assert: or eventually #assert:equals: Why wanting to use a block? Other than #should:raise: and #shouldnt:raise:, I don't really see the point of #should: alone anyway... IMO should: should be deprecated, less is more. I'm possibly the author of several of these #should: sends, so don't take it personnally ;) P.S. or is it easier to restart the block in the Debugger? I cross post to pharo-dev because it's a generic question, and there are a few #should: sends in Pharo-3.0 too.

MOOSEDay@UPMC update
by Serge Stinckwich May 5, 2014

May 5, 2014

Dear all, This is a small update for the MOOSEDAY@UPMC event : http://www.doesnotunderstand.org/MOOSEDayUPMC/ We have only 9 people who register for the MOOSEDAY@UPMC (June 5/6 2014) at the moment and 2 presentations. One of the main drawback is that INRIA team does not have too much money to come this time. What we could do : - we organize a small event on one day (some presentations in the morning and a Pharo/MOOSE sprint). But we definitively need more presentations ? Who is willing to come ? - we postpone the MOOSEDAY@UPMC until september/october 2014, so more people could join (Doru ?). Any suggestions ? Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/
