Whatever application you have - reimplement it using âweb technologiesâ. Whatever data you have - store it in âthe cloudâ and tunnel its transportation over port 80, gain extra points for using XML here. Today, beautiful small things like Smalltalk are ignored by the masses and being laughed at. Andreas

Because the world can be described with tags if you start that path. There are other ways to add metadata to methods. Without tagging. And they don't need to be in the method pane itself. It is like having to specify protocol because there is no list pane to create them. HernÃ¡n > > About python decorators I disagree that are similar to pragmas.

The Smalltalkhub repository page... http://smalltalkhub.com/#!/~StephaneDucasse/Tetris shows... MCHttpRepository location: 'http://smalltalkhub.com/mc/StephaneDucasse/Tetris/main' user: '' password: '' So you are missing the '/main' and also note the change of '/#!/' to '/mc/' , which caught me out a few times. cheers -ben On Sat, Feb 7, 2015 at 11:02 PM, stepharo <stepharo(a)free.fr> wrote: > Hi guys > > I should be doing something obvious totally wrong but I cannot connect to > > MCSmalltalkhubRepository > owner: 'StephaneDucasse' > project: 'Tetris' > user: 'StephaneDucasse' > password: '' > > using > > MCHttpRepository > location: 'http://www.smalltalkhub.com/StephaneDucasse/Tetris' > user: 'StephaneDucasse' > password: '' > > I tried all kind of combinations. > > MCHttpRepository > location: 'http://smalltalkhub.com/#!/~StephaneDucasse/Tetris' > user: 'StephaneDucasse' > password: '' > > open so this is a progress but I cannot see the files inside. > > > Stef > >

In 1978, a system in which a low-level integer was represented as an object with behavior would have been perceived as a rediculously wasteful idea. And can you imagine someone seriously suggesting something so wasteful as automatic memory management? So if the "same" system was being designed today, it might very well include new concepts that today are perceived as wasteful. Some of those concepts might turn out to be very good thing once we get used to them. Dave
