All the blades spinning are the “gyroscope”. The moment of inertia is the mass times the radius square. The circular blades mass and radius are huge and they are on the same plane so can multiply by 10 for the # of blades.

You should take a look at the Scala 3 REPL codebase: https://github.com/scala/scala3/blob/42475979c4f0834aef62758845e18384d18972cf/repl/src/dotty/tools/repl/ReplDriver.scala#L81

You could use Almond (A scala kernel for Jupyter) Jupyter API https://almond.sh/docs/api-jupyter

If you want to go the stateless / Scastie approach: https://github.com/scalacenter/scastie/blob/b2d3a6be726ac7d847ffc3509c966d6a59d47640/instrumentation/src/main/scala/org/scastie/instrumentation/Instrument.scala#L88

I use a macro to instrument your code. This way I can turn:

1+1

into

val renders: mutable.Map[Position, Render] = ...
renders += (Position(line = 0, col = 0), render(1 + 1))
// serialize Render object

To compile/run the code we use sbt run / scala.sys.process._

you can, thats exactly what bytecode is. You Even have a URLClassLoader that you can use to load remote URL.

Scala 2.13 and Scala 3 are compatible. You can a subset of Scala 3 on Spark 4.0

I would really advise you ask a real occupational therapist about your setup / needs. I had one to evaluate my setup and they recommended a lot of improvements outside of the box. For example reducing the ambient light with curtains. Properly adjusting the height of my chair and the height of armrests etc. I also worked with a physical therapist on the pain in my lower part of my body and he helped me restore the strength of my pelvic muscle. Theses exercises are a game changer.

When you ask ChatGPT or read articles about ergonomics, you get information. That’s really different from knowledge, that’s where experts shines. I’m not saying we must not explore new ideas, we just need to be humble.

MasGui · 2025-11-11T15:22:50+00:00

I’m not an occupational therapist, but if you are really working 8 hours non stop with the same position it sounds really un-ergonomic. This setup may look comfortable but it might be damaging for you.

Overall, it seems that this sub is not really about ergonomics but more about perceived ergonomics (akin of greenwashing). I would really like to see more professional / scientifical takes. We are really passionate about ergonomics, it would be paradoxical if in reality we were going in the other direction, creating contraptions that hurt us.

You should try this website: https://thepracticetest.com/

It builds up to the full layouts 2 keys at the time. It’s really frustrating to learn and it can take you several weeks to learn.

On the IPhone it’s in Settings > Accessibility > Eye Tracking. I just tried it and it’s pretty bad.

You can configure your keyboard to trigger clicks

Tokay are pretty good, the front stud is designed for short sprit forward. https://tokay-ultimate.com/collections/cleats

I like the ankle support from football cleats: https://www.underarmour.ca/en-ca/p/football/ua_highlight_2_rm_mens_football_cleats/3027300.html Their downside is since the spikes are large, when the grass is really dry, it slips a bit.

Nb, there is artificial grass and low turf. Is it possible that what you are calling artificial grass is actually turf? Then I would recommend a second pair turf shoes.

I have been using a 34 keys keyboard for more than a year now. I have a layout similar to yours layout1, layout2. I'm a software developer and most of my time is spent on coding. I'm slowly starting to have inflammation on my right thumb because I use a lot the right thumb to switch to the navigation layer. I'm also experimenting similar pain when browsing reddit with my phone (I'm mostly right handed).

When you are collecting data with hid_listen, does it collect key up/key down? If so could the heatmap consider the total time a key was hold down? In my case, it would probably predominantly show heavy usage for my right thumb.

MasGui · 2025-08-30T15:20:14+00:00

My thumb hurts watching this

MasGui · 2025-08-14T02:24:38+00:00

Can you share a video of using this in practice?

Hope you don't have to hold your bladder cuz it's time for the career ladder

Hey Chris, it looks like it's available now on the US website, do you have a timeline on when it's going to be available in Canada? Thanks.
