Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Old version of offline Scratch that had a secret OS
Also, it's not really an "operating system", nor was it implemented by the ST. It's just part of Squeak (you got the name right), the "engine" Scratch 1.x was made with (which lets you edit the code in the same window it's running in).

Ask HN: Alternatives to organizing code in files and folders?
Just downloaded https://squeak.org/ to play around with this concept.
I wonder if there is already a modern tool/suite for Node/Python inspired by Smalltalk...

What are some important differences between the popular versions of OOP (e.g. Java, Python) vs. the purist's versions of OOP (e.g. Smalltalk)?
AFAIK the major SmallTalk distributions are https://squeak.org/ and https://pharo.org/. I've heard that Pharo is more complex and "practical", while Squeak is more educational and beginner-friendly. But both stick to their roots with "everything is an object or method", extreme reflection, and integrated runtime/IDE.

Ask HN: What software stack to select for this boot to code computer?
Your concept looks nice, it reminds me a bit of the Lisperati: https://www.hackster.io/news/the-lisperati1000-is-a-cyberdec...
So, did you consider Lisp or maybe Smalltalk? Plan 9 or Inferno might also be options.
Plan 9 comes in different variants, the "classic" one (with a Raspberry Pi port by Richard Miller) or 9front, an Inferno porting tutorial can be found at https://github.com/yshurik/inferno-rpi
Lisp and Smalltalk can run with or without Linux underneath, e.g. on the Raspberry Pi.
Bare-metal Lisp is available with interim: http://interim-os.com
Finally, bare-metal Smalltalk is available in my crosstalk system: https://github.com/michaelengel/crosstalk
Of course, Lisp and Smalltalk can also run hosted under Linux, e.g. using Squeak (https://squeak.org), Pharo (https://pharo.org) or InterLisp (https://github.com/Interlisp/medley).
Or - a crazy idea - build an emacs-only machine. That would be fun! :)

Smalltalk-80 on Raspberry Pi: A Bare Metal Implementation
Author here, feel free to ask any questions you have :).
It's amazing this little project shows up again here. So far, I received a lot of very positive and friendly feedback about this little pet project of mine.
The whole project would not have been possible without the work of Rene Stange, who created the circle bare-metal library for the Raspberry Pi (https://github.com/rsta2) and Dan Banay, who created a C++ implementation of the Smalltalk-80 VM (https://github.com/dbanay/Smalltalk). I mostly hacked together some glue code...
If you want to dig deeper, the Blue Book by Adele Goldberg and David Robson (scan provided by Stephane Ducasse, thanks a lot!) is _the_ reference on both the language and the structure and implementation of the underlying bytecode VM: http://stephane.ducasse.free.fr/FreeBooks/BlueBook/Bluebook....
Beware, though it's fully functional, crosstalk is still limited by constraints of the original Smalltalk 80 system - e.g. in terms of color (black and white only), possible screen resolution (2^20 pixels, the system crashes if you try to increase the resolution beyond this) and available memory (~1 MB!).
Nevertheless, I think it's a rather authentic reproduction of a more than 40 year old system and I learned (in a comment thread on a completely different topic) that one of our fellow hackernews regulars used it to teach his kid Smalltalk programming - love it! I haven't tried to optimize it significantly, so there's no JIT compiler or bitblit acceleration using the Raspberry Pi GPU.
There's a more modern bare-metal Smalltalk implementation based on Squeak (https://squeak.org) for the Raspberry Pi by Pablo Marx, though this seems to have some stability problems according to the author: https://github.com/pablomarx/RaspberrySqueak
Finally, if you are interested in alternative bare-metal language/OS environments for the Raspberry Pi, you could also give Lukas Hartmann's (of MNT Reform notebook fame) Interim OS a try: http://interim-os.com

Ask HN: Programming Without a Build System?
Came here to mention Smalltalk. In things like Smalltalk-80 and Squeak, there was no build system, there are no source code files, there isn't anything but the Smalltalk Development Environment. With something like ENVY/Developer, building involved generating an exported image from the environment.
If OP wants to try it: https://squeak.org/

Programming Portals
She missed the biggest ‚programming portal‘ of all: Squeak (Smalltalk) (https://squeak.org/)
Inspecting objects, ‚live‘ coding, a GUI that's intimately tied to its CLI - that's exactly Squeak!

Making Smalltalk on a Raspberry Pi (2020)
I don't know why this popped up again now, but it's nice to see that some people are still interested in this little Smalltalk 80 system (I'm the author, happy to answer your questions...).

Allwinner D1 Xv6 Port
Author here - this xv6 port to the D1 (based on the riscv64 xv6 version developed at MIT) is an experimentation vehicle for me and my students since working with qemu alone can be a bit boring and it's easier to test some feature in a tiny OS. Of course, it's also fun to work on it...
"...won't be big and professional like gnu." :)
Based on the experiences with xv6, we are also working on porting some other non-mainstream systems to RISC-V hardware, including Plan 9, Inferno, Oberon, Smalltalk-80 (see my Raspberry Pi bare metal ARM version at https://github.com/michaelengel/crosstalk) and the f9 microkernel.
If you have any questions about the xv6 port just ask.
Shameless plug - I'm looking for a PhD student to work on OS/compiler/architecture-related topics in my research group here at Bamberg University (in the northern part of Bavaria in Germany).
If you know someone who might be interested, please let them know...

On Learning Smalltalk
What if those already-used tools weren't as-good for writing Smalltalk programs?
----
> … its own OS and GUI.
Well there are examples of bare metal Smalltalk (I'm guessing we could say the same of Java?)
https://github.com/michaelengel/crosstalk
- Are there any materials that go through the internals of smalltalk and/or teach you how to implement a smalltalk-like language?

- FreeBSD (https://wiki.freebsd.org/arm/Raspberry%20Pi)
- Interim Lisp OS (http://interim-os.com - this runs on Raspi 2 only, so porting to the ARM v6 in the Raspi 1 would be a nice project) - btw., this is a project by Lukas Hartmann, who is also the creator of the open MNT Reform ARM laptop (https://mntre.com)
- (shameless plug) my bare metal "crosstalk" Smalltalk-80 (https://github.com/michaelengel/crosstalk)
I'm pretty sure this list isn't complete...
Some operating systems are not supported at the moment:
- OpenBSD only seems to support the Aarch64-based models 3 and 4
- Haiku seems to be looking for a maintainer for the Raspberry port
What are some alternatives?
