Sounds all too common. Better to do a few things well, so you can enjoy doing it. Half doing something is not so much fun. Don't let yourself get overwhelmed with too high expectations. Building takes time. Keep chipping away at small goals, and make sure you have fun. > > Like I said in the OP, I'm new to this Twitter thing and I really didn't > know how to use it. > > Maybe you need to drop something, and/or soak up using Twitter in a non-Smalltalk way to "get it." Actually I've never used it myself. I must be getting old :) cheers -ben

You summarise well the kind of code I do not like. isNil everywhere and horrible tests.

Re: [Pharo-dev] The Smalltalk Renaissance Program

by stepharo

It depends what is the level you are looking for. We are working on lectures and books for second and third year university students. Now for kids I do not think that it matters if this the language or software is writting in Smalltalk. Stef Le 4/1/15 23:25, horrido a Ã©crit : > I am intrigued.

Out of the box we should have much better color algorithms. For example decent palettes should follow.

Re: [Pharo-dev] [Bulk] [Bulk] Can MongoTalk execute plan javascript MongoDB queries?

I was close, but I was using $or: instead of $or, and I was missing one level of asDictionary. Just for the archive, thereâs one more query I needed, which was to find an object based on itâs object id. I ended up using: voyageId := Integer readFrom: (request at: #voyageId) base: 16. someModel := SomeModel selectOne: { '_id' -> (OID value: voyageId) } asDictionary. This is a web app using Teapot and Mustache, so I write the voyageId out using: self voyageId value printStringHex

CubeHelix integration (issue 14648 in update #40423)

by Torsten Bergmann

What is the reasons for integration of class "CubeHelix" into standard Pharo image: https://pharo.fogbugz.com/f/cases/14648 So far the class is not (yet) referenced. Would'nt it make sense to have "Chroma-CubeHelix" as external loadable package? Thanks for any clarification! Bye T.
