Wow, I wouldn't go there in that particular article. But things like: (groups at: (aBlock value: each) ifAbsentPut: [ OrderedCollection new ]) add: each Especially when they are in Collection>>groupedBy: aBlock could make cool other articles. There are also Matrix etc which are understandable by people and add value. I guess you may have some Bio samples here. Sven, thanks for taking the time to write those articles on medium. They look great and I enjoyed them immensely. I pushed me to look into how to write for that website. That a step :-) Phil On Wed, Jul 9, 2014 at 9:11 AM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > Hello Sven, > > I will try to give some feedback for you.

Hello Sven, I will try to give some feedback for you. My major issue is that the objects you use are pretty basic. There is no reason to put limits with so many contributed packages. Visualizations have impact and you could use Roassal, GraphViz, CodeCity, GraphET. SQL is also of interest for many developers. Or Big Data which is a requirement now. An example with Spec and DynamicLayout would be cool. For reverse engineering there is Moose and you could show an overview pyramid maybe? A one-liner with #linesOfCode would be magic :) About the article: When writing sample code with random, don't forget to add a paragraph explaining the random source. It is /dev/urandom? To randomize a String I write this: (UUID new asString reject: #isDigit) copyWithoutAll: '-'. To count digits (doesn't work for 1 digit but I like it): 42 factorial log ceiling. I don't know how this could be useful besides doing many things: "Split a string on dashes, reverse the order of the elements and join them using slashes". If you could find a example with some real application would be nice too. For Collection messages people is often interested in speed comparisons. Because audience already knows how to do that in R, Python or other language. Hope you could find them useful.

Thanks Sven, It is nice and helpful, I would look at it if I have the opportunity to give a talk about Pharo while in Taiwan this summer.

Mongotalk & db.collection.distinct()

by phil＠highoctane.be

I am now using MongoTalk for a project and I wanted to use distinct. But there seems to be no support in the version that I do have. So, I had a look under the hood on how the driver worked. I came up with this: mongo := Mongo default open. db := mongo databaseNamed: 'somedb'. aCommandDict := { 'distinct' -> 'somecollection'. 'key' -> 'XYZ'. 'query' -> nil } asDictionary. reply := db command: aCommandDict. (CollectionValidation on: reply) isOK. distinct := reply at: #values. It would be nice to have some support for the distinct command in MongoTalk. Especially in order to populate dropboxes etc with choices. I have been looking at Voyage too but the data is not produced by my application, so there is little use for me to have #instanceOf fields etc. I will also need aggregation commands on my data set. Are these things somewhere to be found or do I have to look into how the shell does things and move from there? TIA Phil

Feel free to ask questions, in this mailing or in some other about Roassal. We will try to provide all the support you need.
