I'm pushing the performance of our Rust-based SOM interpreters, and I wrote a quick blog post about an optimization I recently implemented. Gonna try to make this more of a regular thing for extra motivation (and hopefully valuable feedback) https://t.co/hHyaB3PGtB

And here seems to be the GitHub repository:

How cool is this?!

HaSOM, a bachelor thesis describing a SOM implementation in Haskell 😍😍😍😍

Thesis supervised by @fikovnik.

Learning Haskell is now a little higher on my todo list.

And reading this thesis!

It has a very neat overview of the language.

Yepp, part of the SOM family tree 😀

All kind of nuggets in there: https://t.co/0T7gnZNE4w

An old paper about OOVM and Smalltalk in embedded development back from 2003. It also explains why it made sense to implement the Java HotSpot VM in "Smalltalk style" with a metaclass hierarchy (although Java does not have classes/metaclasses as objects):

The SOM-C# author made SomSom work as well.
I guess this means this SOM implementation is mostly feature complete! 🤩

Someone on the internet ported SOM to C#:

And it passes almost all tests. 🥰

It’s not yet running SomSom, think the command line handling doesn’t match the latest version.

But still, great stuff 😀

After making sure that my RPython SOM interpreters are pretty much the same, except for interpreting either abstract syntax trees or bytecodes, seems like I got the bytecode interpreter to break even on one metric.

Though, not the one you may think.

@smarr That's super spiffy! I'm working on a SOM-in-SOM project myself: https://t.co/wFtIHxh9Xi
When done, it will compile SOM to C. I only work on it when camping though, but camping season starts again soon. I'm really happy with how the parser reads like BNF: https://t.co/HtyXXhVCXf

Why implementing SomSom, a Metacircular SOM you may ask?

Because a language implemented in itself is a thing of beauty. It's fun. It's exiting. 🤩🤓

Thanks @TravisCI for the years of support. 🖖

Hello #GitHubActions!

Now, if just someone could stop adding primitives to SOM, or would at least implement them for all SOMs, this thing would also be green 😅

What am I spying here?

A port of AweSOM to Cuis Smalltalk https://t.co/DTqZeixUxj

Language implementation people:

If you're working in industry, but do things that are interesting for workshops of industrial+academic researchers, would it make it easier for you to submit a blog post as talk proposal?

From here, we can start exploring how things work.
Perhaps how the sending of a message, is done, which is what we find in the executeDispatch() method.

JsSOM is a "zero infrastructure" SOM implementation.

Just open your browser and give it a go: https://t.co/UcP9cC2pGB

In the Chrome DevTools, you can even edited it live!

But, we're more interested in how interpreters work.
So, let's open your browser's developer tools, and run:

1 halt.

The halt message stops execution in the debugger, and works not just on 1, but on all objects.

Only AweSOM is missing. But a lot of green 💚💚

@CaptainHats Nothing secrete. It’s just that the Slack links timeout after 30 days…
