Interesting!

Were you using IBM Visual Age Smalltalk?

dharmatech··on RacketCon Is Saturday
Very interesting! Nice to see the postgresql store.

Thank you!

dharmatech··on RacketCon Is Saturday
This is cool! Thank you! I'm a fan of C# and dotnet. Nice that you used F#!

Yup!

Here's a video demo of the code completion in vscode:

I've been messing around with a language that I summarize as:

ALOE = Scheme + Smalltalk + Types

https://github.com/dharmatech/2026-09-02-aloe-racket

Prototype is in Racket.

dharmatech··on What Zig felt like, coming from Rust
You mention there that you like Ruby and that you wanted Ruby with types (and that you looked at Crystal).

I've been messing around with a language that I summarize as:

ALOE = Scheme + Smalltalk + Types

https://github.com/dharmatech/2026-09-02-aloe-racket

One of the examples is a very basic computer algebra simplifier:

https://github.com/dharmatech/2026-09-02-aloe-racket/blob/ma...

That simplifier is based on a computer algebra library in Scheme:

Hey Ashton,

I see you're with PLT. :-)

Since Racket is built on Chez, you might like this. It's an Emacs-like editor built in Chez Scheme:

Super cool to see a new Scheme on DOS.

This sounds so cool! Do you have this shared somewhere?
dharmatech··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
Hey Aurornis,

I definitely haven't looked into the underlying models of histamine to see how things work.

My observation is that, when I avoid histamine related foods, I sleep longer and fall asleep faster. The naive model is what led me to try that. But I totally acknowledge that there's likely way more at play under the hood. And I would like to know more about why this works! Or, at least why it works for me.

Thank you for pointing out the complexity of the underlying mechanism.

dharmatech··on Sleep regularity is a stronger predictor of mortality risk than sleep duration (2023)
Yes, magnesium has helped.

For me, avoiding high histamine foods as well as histamine liberators had helped tremendously.

The theory:

Anti-histamines like Benadryl make you sleepy by blocking histamine.

Well, instead of blocking the histamine, get rid of it in the first place by avoiding histamine foods (for example aged or preserved meats).

Cool!

dharmatech··on Show HN: Wyrm – Solve algebra by touch, built on an open-source soundness engine
The interface is beautiful!

Just curious... Did you implement each app natively? I.e. Swift and Kotlin? Or were you able to use a cross platform framework like Flutter?

dharmatech··on Show HN: Wyrm – Solve algebra by touch, built on an open-source soundness engine
Very cool!

Here's a demo of a library for interactively eliminating variables from sets of equations:

https://youtu.be/7ysUdxTfKhU?is=lE5o9Besk1XNnggP

Source:

https://github.com/dharmatech/combine-equations.py

The interactive gui part starts at 4:08. Before that is the setup and context of the example.

If you ever move in the direction of supporting sets of equations and isolating variables, consider using colors to indicate known values and unknown values as is done in this library.

I test this library on exercises you'd find in college physics (motion, constant acceleration, projectile motion, Newton's laws, etc.) since these involve sets of equations and eliminating variables so that you have expressions in terms of known values.

The above demo uses a jupyterlite notebook, so everything runs client side in the browser. No server side kernel necessary.

To use your interactive fluid style in this library to eliminate variables, I could see the user first isolating that variable. Then dragging that variable they want to eliminate over an instance of that variable in another equation. So that's effectively the user saying "replace this variable with this expression".

dharmatech··on PeerTube is a free, decentralized and federated video platform
> As a professional YouTuber, the main issue I instantly see with this is the lack of monetization.

That's a feature, not a bug.

dharmatech··on A native graphical shell for SSH
Alan Kay once strongly critiqued web browsers. He argued for a much simpler architecture.

Your experiment somehow reminds me of the better approach that he was hinting at. I.e. I think he would appreciate your experiment as well as the neuroscience in your background.

Your project is really cool.

And, when a project announcement upsets this many people, it's a sign you're on the right path, or at least an interesting one.

dharmatech··on Rubish: A Unix shell written in pure Ruby
Cool project!

Just for fun, looking at code count as a rough measure of complexity.

rubish: 26,842

rc (plan9 shell): 5,888

To be fair, rubish does a lot more than rc. rc is pretty minimal.

I definitely think we should be exploring decentralized approaches to services we use.

I also would like to see an emphasis on local-first approaches.

Hey pjmlp (waves),

I know you've been an advocate for OSes and languages that are outside of the mainstream.

I finally got around to living in plan9...
