Re: [Pharo-dev] beta testers for the new version of the Pharo mooc

by Christopher Fuhrman

Hi Stef, At the very least I can help, but I will try to find some students. I just upgraded to WSL2 on Windows 10 and would like to see how Pharo performs. C.

Re: Energy efficiency of Pharo/Smalltalk

by Mariano Martinez Peck

Hi there, We did a related experiment with VA Smalltalk and other languages like Python, Java, etc... the context was how a JIT compiler can also help you reduce energy consumption...which could be very important for IoT. We did experiments on a Raspberry Pi, run some benchmarks and with some hardware tool we were measuring the wattage. You can see the whole presentation here: https://youtu.be/2xO0ohUNnug Hopefully this can get you started with Pharo experiments.

Hi Stef, Daniel (in copy), one of my students, is willing to help. He started with Pharo one year ago, he also read the previous version of Pharo mooc. Regards, Juan P.

Re: exercism bowling challenge

by Russ Whaley

Yes, my thoughts - since I'm not as technical as the rest of you: BowlingGame class "runs the game a calls each frame to 'process'" - frames (1-10 aFrame objects) - score (aScore object) - currentFrame Frame class "frame handles #throws, pins remaining, and lets Game know when to advance to next frame - frameEnd" - frame# - throws (1-3 aThrow objects - aFrame controls 10th frame 3rd throw) - score (numeric) Throw class - frame (the frame I belong to) - throw# (incremental numeric 1-3) - pinsKnockedDown (0-10) Score class - frames (same as BowlingGame class) - methods to calculate score, once a frame score has been determined, it is stored on the frame and the score calc simply picks that up and moves forward on each successive score calc (after each throw - called from inside of aFrame) This will be a fun little diversion. I'll create a simple UI and engine that will randomly return a number of pinsKnockedDown when pressing the spacebar to roll the next ball.

Energy efficiency of Pharo/Smalltalk

by Jonathan van Alteren

Hi all, I am interested in energy efficiency metrics for Pharo (version >=8). Just now, I came across this research and related GitHub project: â¢ https://sites.google.com/view/energy-efficiency-languages â¢ https://github.com/greensoftwarelab/Energy-Languages Unfortunately, the paper mentions that Smalltalk was excluded from the results because the (VW) compiler was proprietary :-S However, the GitHub repository does contain Smalltalk code and results, but I haven't been able to evaluate those. [1] Does anyone here have more information on this topic? The benchmarks seem to be low-level algorithms. Although that is useful, I think that a better argument for Pharo/Smalltalk efficiency is that a good OO design (e.g. created using responsibility-driven design with behaviorally complete objects) will be a better fit, can be much simpler and will thus be more efficient during development, as well as easier to maintain and evolve. [2] Has anyone done any research in this area that can quantify this aspect? Kind regards, Jonathan van Alteren Founding Member | Object Guild B.V.

The beautiful thing about flashcards in a dynamic system like Smalltalk is that one could define an API so that *any* domain object could be turned into a flashcard, like the birthdays of your contacts (silly example but you get the idea). I did extensive reading on the SM-2 creator's website and played with Anki a bit. It's been on my endless TODOs to do something simple like Anki in Pharo... ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: Space Based Repetition

by Tim Mackinnon

Hi Sean - this implementation is Leitner, which would be ok for my needs, although I donât quite know how you choose or specify the probabilities that are needed for this particularly implementation (and Leitner descriptions donât mention this, but I can see the intent is to give you a random flashcard favouring new or unlearned cards and occasionally giving a learned card - but Iâm not quite sure how you decide what to specify for thatâ¦ Iâm enquiring. SM-2 always intrigued meâ¦ and would be cool to plug that in and compare - but was trying to avoid the inevitable rabbit hole and not get the actual task done (Which it sounds like you thought tooâ¦) Tim > On 30 Sep 2020, at 16:21, Sean P.
