DICOM or DCM images are widely used in medical imaging. Is there a Smalltalk image reader for that format?

Immutability in the VM - is it hard?
by Aaron Rosenzweig May 4, 2014

May 4, 2014

Hello, Why is the concept of âimmutabilityâ special to VisualWorks? Is it something hard to add to other Smalltalk dialects such as Pharo or are there other reasons for not having it? When I read the docs for the GOODS database client it says the following: âThe GOODS client uses this immutability support for change detection.â It goes on to say that this is only for VisualWorks. For Pharo it says that it is generally slow to commit changes because the client to the OODB has to spent extra time detecting change detection. I guess for VisualWorks it is basically âfreeâ to detect a change in an object. Thank you, AARON ROSENZWEIG / Chat 'n Bike e: aaron(a)chatnbike.com t: (301) 956-2319

New Proposal for new Pharo website - About page (with example website)
by kilon alios May 3, 2014

May 3, 2014

I don't like the about page. Its still unclear what Pharo is and I have to agree with the complains we are getting at reddit. So instead of starting a long conversation about how I would want it done , I sat my ass down and made a draft of it so you can see it directly. Please bare in mind this is draft , I just wanted to show you my idea for an About page. You can find the draft here http://thekilon.wix.com/pharo-about I think contributors should go to a seperate page called "Credit" I am open to comments and suggestions.

Re: [Pharo-dev] [Pharo-users] Pharo 3 minor issue

That is apparently a Spec problem (i.e. all buttons created with Spec react like this): ButtonModel new label: 'Right-click Me'; action: [ self inform: 'Clicked !' ]; openWithSpec CC'ing to Pharo dev.
