Streaming API for Pharo?

by Arturo Zambrano

Hi All, we are playing with Roassal for the visualization of Twitter data. So far we used Zn-SSO to connect to twitter and call REST API to get some tweets for playing. Now, we would like to use the streaming API. I could not figure out how to do this with Zn-*. According to Twitter Streaming API docs: Some HTTP client libraries only return the response body after the connection has been closed by the server. These clients will not work for accessing the Streaming API. You must use an HTTP client that will return response data incrementally I would like to know if Zn allows to get data incrementally. Furthermore it would be great to know if there is some example where I can start from. Once we have our toy working we plan to release it to the community. thanks. art

Re: [Pharo-users] [ANN] Spec documentation in PFTE book finished

" Creating a specific UI always starts with the subclassing of ""ComposableModel"". " The above is passive with 2 gerunds. No experienced tech editor should let that pass as an English instruction for an action or task to be performed by a reader - especially if the reader may be using English as a second language or merely know English as a technical language. ALT non-passive sentence "To specify a UI, you must first declare a subclass of ComposableModel." But Smalltalkers use "subclass" as a verb, so we get "To specify a UI, you must subclass ComposableModel first." ALT How to specify a UI : First step : subclass ComposableModel ( we will declare ModelList in this class browser UI example.) Some of the Wiley "For Dummies" books offer good examples, as do some of the "Idiot's Guide" books. Some books in German offer examples only rivalled by books in Japanese. Sadly, English invites abstract constructions using Latin roots instead of simple Anglo-Saxon verbs. Japanese at least places a verb at the end of the sentence and has "ga" to distinguish true subjects from mere topics indicated by 'wa". German has the frightful practice of ending sentences with prepositions. Relatively more synthetic or analytic languages pose different challenges for technical clarity in explaining practical tasks such that an example can serve as an exemplary instance for future reference to refresh recall and to facilitate recognition. Boeing and NASA have some experience here : Apollo 13 has a reminder of the challenge of impedance mis-match and "round" meets "square"component. Note: the practical "principles" for landing light planes with power are not those for landing heavy jets with power, partly because piston engines do not "spool up" ; runway "flare" is not achieved by "Looking at how close you are to the runway" but must be learned - partly on the ambient flow of a visual gradient ... except in marginal visibility or over water or over waving tall grass ... Clear technical English is a challenge : it is not met by "knowing English" anymore than landing an airplane is achieved by knowing the names of the yoke and rudder ( and beware of rudder-less aircraft ! ) Can someone other than me volunteer as a technical editor ? It is not a matter of having the facts right or mentioning the "Gotcha's". For an MVP example, I would suggest giving the use of colour some serious thought : experiment with it. It is now used in some new bilingual dictionaries to very good effect. If you have never looked at a surgical manual for a new procedure, I would suggest doing so. Ask a spouse about the most useless instruction manual for the DIY project that refused to assemble. The writer of the latter also "knew" enough English to write the instructions. No offense intended WHATSOEVER and I hope none taken by anyone. As Marcus may recall, I now have more difficulties typing at a keyboard and even in the short term I may become less helpful and less useful. Perhaps there is a tool for blue-pen and red-pen : PDF annotations ? There should be a Smalltalk UI for editing text in tX ... ;-) R Canada PS For some readers, MVP can be no more obvious than MVC ; believing in MVP as being more obvious could impede presentation. MVC was a stumbling block for many learning to build UI's in various Smalltalk dialects in the past. Do you recall handing off a Smalltalk project for maintenance to someone who believed in C++ but was moved to your ST group or team ? I remember this very clearly. You can learn a lot from a dummy. I learned a bit from having taught English as a second-language to Vietnamese and to Poles that I did not learn teaching French students. A book for the "Enterprise" is surely not aimed chiefly at those of us who have enjoyed drinking the Kool-Aid ;-) On 12 February 2014 11:08, Johan Fabry <jfabry(a)dcc.uchile.cl> wrote: > Hi all, > > I am happy to announce that Ben and I finished the documentation of Spec > for the Pharo For The Enterprise book.

Re: [Pharo-users] mathematical models

I forgot to say that i downloaded MOOSE and Kendrick packages. Is there somebody who is currently working with this stuff? Is there any kind of tutorial? Thank you! From: prova213(a)hotmail.it To: pharo-users(a)lists.pharo.org Date: Thu, 13 Feb 2014 10:50:39 +0100 Subject: [Pharo-users] mathematical models Hi Guys! I'm going to start to teach as assistant professor of Operative Research, and i'd like to teach some stuff of Pharo. I was wondering if there are some Packages about mathematical models as Lotka-Volterra or other models about the dynamics of biological systems already implemented (with plot too). Thanks for the help.Paolo

Re: [Pharo-users] Applications, features and unit tests

by Leonardo Silva

Hi Damien, By feature I mean any user-visible functionality that needs to be tested. Like you said, one feature can have many tests. The important thing for me is to know, given a unit test, what feature (high level) is going to be tested. If you name your tests putting the name of the feature as a prefix, then I can do this mapping.

Re: [Pharo-users] Improving Strings Manipulation topic

by Tudor Girba

Hi Daniela, Great. Please take a look at the extensions we have for collections in general (including some string goodies) in Moose: http://www.smalltalkhub.com/#!/~Moose/CollectionExtensions Perhaps they can be of interest. It would be great to work on integrating them into Pharo. Btw, where are you based?
