Fuzzy Thinking in Smalltalk

by Richard Kenneth Eng

>From Lorenzo Schiavina: https://smalltalk.tech.blog/2020/02/04/fuzzy-thinking-in-smalltalk/ There's a minor issue with WordPress: embedded slideshows steal the keyboard focus so that you can't use PageUp and PageDown keys to navigate the webpage. I've reported it to WordPress and they're working on it. I'm still looking for more blog post submissions. Let's keep this blog alive!

Viewing all Spec icons

by Steve Quezadas

Is there a "smalltalk" way of displaying all the icons that are available in spec? Or a website with all the images, just so that I can have a "bird eye's view" of the data?

Excellent! I've bookmarked it to show others. That answered my questions (and those that others will inevitably ask, too). -t (Well, maybe one more: What's the criterion for when the robot stops?

It took four takes, but I think I've got it nailed for good: https://youtu.be/ArEWif7JUBk I'm hoping these kinds of videos from the competition will be great advertising. We shall see... -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Dictionary removeKey: very low

by PBKResearch

Pierre Itâs all to do with rehashing. A dictionary is stored as an Array of Association. After a key and its corresponding association is removed, the remaining entries are rehashed from the removal point to the end of the array. By doing the removals in natural order, you rehash the whole of the remaining array after each removal. Try doing the removals in reverse order; on my machine it reduces the time from 6 seconds to 6 milliseconds.
