[OT] TDD is dead. Long live testing. (DHH)
by Sven Van Caekenberghe April 23, 2014

April 23, 2014

More or less what I think: testing is necessary and should be pragmatic & fun, not a dogma http://david.heinemeierhansson.com/2014/tdd-is-dead-long-live-testing.html

Modal widget
by Hilaire Fernandes April 23, 2014

April 23, 2014

Hello, In a morph hierarchy I would like one morph child to be modal (i.e. all other morphs are locked and the system is waiting for the user action on this modal morph). I need this for dialog encrusted in a parent morph (instead of windowed dialog flying around the system). In the screen shot example, only the "ok" button is actionable. I can hack with appropriate lock and unlock in the morph hierarchy, but it is not clean and not exactly modal because the system does not wait for the user answer. Any idea to do it more cleanly? Thanks Hilaire -- Dr. Geo http://drgeo.eu

[ANN] Gravatar for Pharo Smalltalk
by Torsten Bergmann April 23, 2014

April 23, 2014

Hi, The "Gravatar" project is a simple wrapper for the Gravatar API allowing you to get small avatar images for a given registered email address. You can easily access and use it in Pharo. The project is located on STHub at http://smalltalkhub.com/#!/~TorstenBergmann/Gravatar To install just open the Pharo configuration browser and load "Gravatar" from there. You can also install manually, read the docu on the project page. Some examples: Gravatar imageURLFor: 'example(a)mail.com' If you require a different size just evaluate: Gravatar imageURLFor: 'example(a)mail.com' size: 32. If you need the real image you can use Pharos Zinc components suite to get the image form over HTTP and open it on your Pharo desk: |form| form := ZnEasy getJpeg: (self imageURLFor: 'example(a)mail.com'). form asMorph openInWorld In the end it is just a simple class - but I think it may be useful for others too. Thx T.

Re: [Pharo-users] Error when trying to initiate Pharo in Ubuntu 64 bits

>Whoever compiled it deserves commendation. Nevertheless, in my opinion itÂ´s an issue to keep in mind for the future; distributions are likely to upgrade their libc at >different points in time, and a good lowest common denominator should be chosen with care, otherwise itÂ´s not really "common" at all. +1 Well known issue. Heard about it first some 7 years ago, when a friend of mine, a FreePascal maintainer, commented: "Ubuntu is Debian unstable, it is not supposed to workâ Stephan

Re: [Pharo-users] Error when trying to initiate Pharo in Ubuntu 64 bits

Hi Gabriel, Version 11.10 of Ubuntu is no longer supported. That ended nearly a year ago. That means that there is no heartbleed openssl update, you might need to compile a safe version from source. And that also means that there is no recent precompiled pharo for it. If you need to use a machine for a longer time, you might want to either use a LTS version, or upgrade regularly. Stephan

Athens question: AffineTransform, AthensCairoMatrix and Float values
by Juraj Kubelka April 22, 2014

April 22, 2014

Hi, We are integrating Athens transformation to Roassal2/Trachel and I have reached an issue. In drawing code I use something like this: -=-=-=- athensCanvas pathTransform restoreAfter: [ athensCanvas pathTransform multiplyBy: matrix; âan instance of AthensAffineTransform" athensCanvas setPaint: color; drawShape: self path. -=-=-=- I have a problem, that sometimes it crashes because it expects a float value (I understand why). I suppose I do not have to keep float values in AthensAffineTransform object. My suggestion is to ensure float values where it is expected. For example the method #loadAffineTransform could be like this: -=-=-=- AthensCairoMatrix>>loadAffineTransform: m self initx: m x asFloat y: m y asFloat sx: m sx asFloat sy: m sy asFloat shx: m shx asFloat shy: m shy asFloat -=-=-=- Right now I have to do that transformation myself whenever I use Athens objects. I see it error prone and I do not see it obvious. On other hand I do not want to keep float values in my AthensAffineTransform, because if user do #scaleBy: 0.7 and then #scaleBy: (1/0.7) I want to get the same original value. Otherwise the image could change its size. The same change could be for other methods in AthensCairoMatrix. What do you think? Juraj

Domaintalk - A Proposed New Project Second Attempt
by Bob Williams April 22, 2014

April 22, 2014

It would appear that there is some interest in the Domaintalk project, but from the responses I received it is clear you need to see my full proposal to appreciate the scope of what is being proposed and determine if it is something that the Pharo project wants to do. The more extensive is currently over five pages of single spaced text and I think that that is excessive for the body of an email and I am not sure if your email system allows attachments. My problem is that I do not have access to a Web site; therefore, I am looking for a place where I can post the proposal document. Some help please.

Gitfiletree error when loading Mapless
by Esteban A. Maringolo April 22, 2014

April 22, 2014

I'm attempting to load Sebastian's latest contribution [1] and when doing so I'm getting an error related with git: "Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists." Looking into the code, I found it is executing this to clone the repo: git clone git@github.com:sebastianconcept/Mapless.git Which if I run in the command prompt I get the same output. As far as I can understand it is trying to access github with the user git. If I clone the project as: git clone https://github.com:sebastianconcept/Mapless.git It works okay. Any suggestion?
