[ANN] humane-assessment.com

Hi, I am happy to announce the new home for humane assessment: http://humane-assessment.com Humane assessment is a new software engineering method for making the assessment of software systems practical and manageable. This is made possible by the Moose analysis platform. The core idea is quite simple: build custom analysis tools to analyze the contextual complexity of your software systems so that you can make better decisions. By decisions I mean anything that has to do with the system: it can be technical (such as, is this concept well encapsulated?, or is my component used the right way?), or it can be broad and strategic (such as, should I refactor my system?). To make it practical we need to be able to craft tools (sometimes complex tools) fast. This is made feasible by Moose, and in turn, Moose achieves this because of Smalltalk. The method also covers process and organization-related problems. If you wish, humane assessment is the coat that can place Moose and Smalltalk within any development team. If you want to promote Smalltalk, perhaps you might want to use this path. I would be happy to provide more information, support and even materials. Cheers, Doru -- www.tudorgirba.com "Be rather willing to give than demanding to get."

So tantalizing...
by Tony Giaccone June 19, 2011

June 19, 2011

Every time I look at smalltalk, I'm blown away with how cool it is to work with and each time I try to get started, my efforts are stymied pretty quickly. I understand message passing, and I understand the basics of the syntax, but I'm having a very hard time understanding how to use the class libraries. I am trying to build a very small app. A simple data editor and browser. I've been able to follow an example in the code (simple grid example). I can now display my objects in a window, with four of the attributes listed in the editor. Now I can select an time and change it in place in the list editor but that change doesn't make it into the "database" (my ordered collection). It is not clear to me at all how to select a line in a MorphTreeMorph. Nor how to save the change when the user tabs out or hits return. Any help would be appreciated. Tony

You can't bring me down: a kind of meta message
by StÃ©phane Ducasse June 18, 2011

June 18, 2011

Hi guys I was thinking after the discussions I got with igor about the efforts we spend on the build servers and vm infrastructure: sometimes we/you have a vision and a good one but people do not get it or do not follow or are busy and do not get that if they would spend 5% of time doing little things then you would not lose your faith or days of work. Yes this is like that: for example igor fixes are not included in VM code. This happens. So may be one of these days we will have to think about what we really want for VMs and do it. Now you should not let people get your vision down. This is too important and fun when your vision is cool. You can't get me down (one of the best suicidal tendencies song). http://www.youtube.com/watch?v=CrctcJqfpXU Stef

Needed hooks to replace ImageSegment and ReferenceStream by Fuel?
by Mariano Martinez Peck June 16, 2011

June 16, 2011

Hi guys. Stef/Marcus are proposing to replace ImageSegment and RefenceStream by Fuel. Maybe in Pharo 1.4 or in the future. So, I need help to understand mostly the required "hooks". So far, I am aware of: *ReferenceStream* 1) #comeFullyUpOnReload: aReferenceStream This message is sent once the object is read from the stream, at materialization time. We already have this in Fuel and it is called #fuelAfterMaterialization 2) #objectForDataStream: refStrm This message is sent once the object is going to be written into the stream, at serialization time. The idea is that an object may not serialize itself as it is but something different. Most of the times, it is a DiskProxy, but not necessary. This doesn't go with the idea of Fuel, where the objects do not decide theirself how to be serialized/materialized but instead delegate to a cluster. 3) #applyConversionMethodsTo: objectIn className: className varMap: varMap This is for class shape changes. We will have another protocol. 4) #storeDataOn: aDataStream This message lets an object decide how to be serialized. *ImageSegment* a) #startUpFrom: anImageSegment Almost the same as 1). So....I am missing more? opinions? which of them are really used hooks? Thanks -- Mariano http://marianopeck.wordpress.com
