  Me too with w3m. Wow, look at the page source! It's an insane amount of javascript. I wonder what it does.

    Evergreens only. Yes it's a whole OS in there, 7mb.

      There are still web devs unable to make the difference between a web site and a web app and how important the web site is in regards of the web app.

        This is an app, the file works from a file:// domain without a local Webserver. It's a different thing than other things you have seen.

The article spells RISC-V incorrectly as "Risk V" in some sentences. This does not feel like the sort of error somebody going so far as to implement this would make. Gut feeling is not good. Unfortunate.

  I just like the game Risk. It boots!

      OK fixed! As you clearly know this space well, what do think would make this project better? I was thinking I wanted to see a heatmap of memory access (pages?), and more detailed explaination of the opcodes, but getting the thing working took quite a while so I got a bit tired and stopped at the booting milestone, but I like the project a lot and now it is in a notebook I can basically probe any part of the system with dataviz tools to make it more tangible. Do you have anything you think would be helpful or cool for learners that you have not seen before in an emulator?

        This is going to be very person by person. e.g. I'd love to see cycles spent in each mode (machine/supervisor/user). Also how much idle (wfi).

        I added a viz for that! Its cool! You can see the transition to user mode https://bsky.app/profile/larkworthy.bsky.social/post/3mjcpkyvr3225 https://bsky.app/profile/larkworthy.bsky.social/post/3mjcpky...

        I love it. In the graph, does it show the highest level of execution within the sample interval, or the current one at sample time?
