One of awesome projects you can play with at squeak.js.org/etoys/

Logic Game, 2005.
I made this logic circuit simulator to learn Etoys, Alan Kay & co.'s programming language for kids. I represented the state of the wires and logic gates with their "costumes" -- there is no hidden state. This makes the behavior of the circuits visible.

I created a video of a 'walk through' of my latest tutorial on creating a simple to-do list web application using CodeParadise. Happy coding!

I've been having fun reviving the Croquet from 20 years ago using @SqueakJS . It's not perfect yet, but a lot of the old demos work (sans collaboration, so far). This is pretty close to the version Alan Kay used to give his Turing Award lecture in 2004:

CodeParadise is a fascinating project using a tiny (~300kb) bootstrapped @pharoproject image that is executed in a web page using a headless build of the @SqueakJS virtual machine. It directly interacts with the DOM using a custom VM plugin.
Check it out: github.com/ErikOnBike

CodeParadise can now save an image to be restarted later as a Single Page Application. All code and DOM are saved. After the snapshot is restarted the application will recreate the DOM and rehydrate the webcomponents. For a small video see: youtu.be/9YUXYuo_HaMOr
Happy coding!

New SqueakJS release 1.1 lets you save Etoys projects (finally!) 🎉
If you're curious about how Squeak use the Garbage Collector to find "image segments" in Squeak, this is the code:
github.com/codefrau/SqueakJS…
Also fixes Scratch project saving and has other minor improvements.

Really nice project with example(s) from @ErikOnBike to bootstrap an own tiny custom image. It is based on Bootstrap from @pharoproject which can not only bootstrap a Pharo image.
Run the image on you CLI VM or in a browser with @SqueakJS VM

Gave my talk about my various JavaScript VMs – @CroquetIO , @SqueakJS , and #Smalltalk78. It was recorded so I will link it when it’s available

Extremely interesting keynote by Dan Ingalls in celebration of Smalltalk's 50th Anniversary. I'm honored he used my virtual machines for his live demos (Smalltalk-78 and @SqueakJS).
Also disappointed that apart from Adele the organizers did not invite more women speakers 🤷🏻♀️

Looking forward to see JsSqueak in action!
Curious how it compares to @SqueakJS.

The next UKSTUG meeting will be on Wednesday, December 29th.
Florin Mateoc will show us JsSqueak - a version of Squeak compiled to native JavaScript.

With the Apple CPU in my new phone, @SqueakJS runs twice as fast as on my 2019 MacBook Pro with an Intel 8-Core i9 chip 😲
Can’t wait to try it on the new MacBook Pro …

In two weeks...
Squeak turns 25 on Friday, 24 September 2021. Let’s celebrate!
We'll begin with an informal online gathering, at xn--88-rha.vc/3plus4/cast. It will start at 11am pacific time (18.00 UTC), and last all weekend, so that folks from all time zones may attend.

Is there already a multiuser SqueakJS based on CroquetIO? 🙃

My week is incredibly busy. But I just did one while waiting for the train … looks much better in action (the Sun is bouncing around and leaving random pen trails).
This is in @SqueakJS, running Etoys (the precursor to the popular Scratch tile scripting system)
ALT Screenshot of Squeak Etoys running on a web browser window. A tile-based script instructs a Sun-shaped sprite to draw pen trails, taking the Pride flag colors from a holder of color samples based on the Sun’s vertical position.

Dan's talk about Smalltalk at #HOPL is about to start.
If you don't know, the HOPL conferences are a very big deal in the programming languages community. It's only held once per decade (!)
And yours truly is getting a mention for her #Smalltalk-78 and @SqueakJS work. So proud!😊

Neat! I should rename the old @SqueakJS JIT to SparkyPluggy: Single pass, no optimizations (and no deopts!), interpreter-compatible stack frames. Very similar design choices 😁
