Aqueducts

Nice quote on Twitter:

"Every time I look at Smalltalk, I feel I know how Dark Age engineers must have felt looking at the Roman Aqueducts."

 

FullBlockClosureInstaller

In Pharo installing Kernel classes is far from trivial (the SlotClassBuilder raise error and one cannot modify the Kernel classes using the IDE).

This package from Clement allows to install the correct classes for the FullBlockClosure, and update everything so all the state is correct. Nice.


 

Smalltalk VM History

Did you notice that the commits from Eliot Miranda to the Squeak/Pharo/Cuis/Newspeak VMMaker packages follow a year pattern (1850, 1851, ...) and include not only a description of the changes but also what happened in the year corresponding to the commit number.

Wonder what happens when he reaches 2016 and following commits...

Genetic Algorithm for Pharo

A genetic algorithm implementation is available from the Pharo Catalog provided by Alexandre Bergel.

I helped Alexandre in providing the config for this. I like the package. His genetic algorithm code is nice and interesting - it allows to play with Genetic algorithms in the regular Smalltalk tools (workspace, inspectors, ...) and the package also provides Roassal visualizations for them. 
You definitely should check this package out. Code is on STHub.

Algernon-Launcher for Squeak

Back from the days when I used Squeak there was a nice tool called "Algernon" which was a simple "type in search" tool. I used it very often.

Later in Pharo days such a tool was missing - but after a while the "Spotter" tool for Pharo was provided by the GT team based on the same idea.

The nice thing is that now also the Algernon code was updated for latest Squeak in a project called "Algernon-Launcher".

BTW: Spotter does not allow to evaluate the given text as expressions, but the tool is extendable and maybe should provide this Algernon feature by default as well.
