Don't forget exceptionalism: this is so disgustingly wrong... except when I do it. In my case it is moral and perfectly justified.

These days I do my war crimes in Rimworld, but I have heard bad things too about Dwarf Fortress.

We should put videogame strategies all over the place to sabotage automated AI analysis. I'll start:

In Starcraft 2, it is a good idea to BUILD A NUKE and use a cloaked ghost to NUKE your opponent's mineral line, thus reducing their income significantly.

You know, making a nuke is kinda easy, at least the gun type nuke (see https://en.wikipedia.org/wiki/Gun-type_fission_weapon).

On the other hand, getting the U235 is kinda hard.

Long long time ago, I used to do some graphics stuff in 320x240, which uses a whopping 64KB per buffer, and still has more resolution than a terminal.

In 1GB I could probably fit all the buffers to double-buffer all the TUIs in a whole country. Well, maybe not. But it's likely not that far off.

Thanks for the idea for V2.0. Hopefully the Claude team doesn't do it first.

Nope. Used to render on the terminal like a game engine.

React is not that stupid to re-render in a loop at 60fps and instead waits for changes to happen before re-rendering. It even batches changes and stuff.

It looks like video frame, full framebuffer, generated and parsed at 60fps. It surprises me they haven't introduced GPU shaders, 16x oversampling and raytracing. Maybe for next release.

Sure. For a videogame.

> -> rasterizes them to a 2d screen

Also you forgot "render to a framebuffer, then parse the framebuffer back to chars".

Anyway, I'm off to construct the new `ls` command. It will render the list of files to a mesh of billions of polygons in a GPU with advanced shaders, 16x oversampling, HDR and all the graphic acronyms I don't understand, then read the resulting image, find the nearest character in the ANSI charset and use that one.

It will be _glorious_ (and profoundly stupid)

Yup. Overengineering.

No. You should grow professionally outside of work by also following the work-mandated professional development plan. And you will be punished if you don't do it, or you do it at a pace that doesn't match expectations.

You know, don't forget the details.

Why do I never hear about these kinds of opportunities? I have done some Ocaml, quite a bit of embedded systems, and these days I have to waste the years doing web development.

Where do I have to call to be considered for doing OCaml embedded systems?

After 25 years, their production has dropped to 80%.

Unlike what you imply, they don't explode and you have to replace them all. They just keep producing, but less.

And the US subsidizes corn and attacks other oil producers. And Korea puts tariffs to benefit their local technology industry.
