I in fact had this and a few other variations I've seen before in mind when I posted this

There was that one writing app that offered reviews by simulations of famous scholars, which everyone found deeply tasteless and I haven't heard about in a while and can't remember the name of now

I see a commonly repeated sentiment on Bluesky, the website for 38 year olds, that says everyone was excited by the advent of the Internet in a way that far exceeds any excitement for gen AI/LLMs. The thing is, that's not strictly true.

Huh, that's pretty good. How is it on smarts?

I would avoid anything that didn't come out in the last year or so if you want it to call tools and be an agent at all

If it's low bandwidth you should be able to use remote models just fine, they're only streaming tiny amounts of text in and out. Droppy connections will suck though

What can one run there? Recently came into (via great personal expenditure) an M5 with 48GB

Ooh yeah you probably can't get the context window too long either can you?

Actually, you might want to check out OpenCode Zen in particular. They often/usually have one or two free models, frequently "stealth" ones with silly codenames, which are most often Chinese labs testing out new offerings before actually deploying them

Dan @handackett.bsky.social · 04/10/2026
You might have a better time if you look into running some of the open-weights models via e.g. OpenRouter, or OpenCode Zen. You shouldn't do this if you have concerns about sending data or money abroad. But, you can get lots of usage for dirt cheap compared to American frontier lab offerings

The RAM is a big limiter; if you have a 6B model quantized to 4 bits, that's 12GB just of weights already. But maybe there's some clever setup with expert cacheing that could work for you
130
Dan @handackett.bsky.social · 04/10/2026
That is indeed a nice laptop! But even smaller models are pretty heavyweight to run. If you want compute/memory intensive things to happen on the same machine as where you're running the model, it's probably not going to work very well, too much resource competition

Dan @handackett.bsky.social · 04/10/2026
I think you're going to have a hard time with that RAM running anything tremendously intelligent at a high token rate, but I might be wrong! Ironically, best way to get started is probably use Claude Code or Codex and get it to figure out what all needs to get done

Dan @handackett.bsky.social · 04/10/2026

I was very surprised in one of those recent scrape your neighborhood toys to find that there are people who post significantly more than you, but I forget who or whose scraper

Forgot where that one came from

Dan @handackett.bsky.social · 04/10/2026
? I think with causal attention, the usual way of doing things lets you reconstruct identical KV cache from just the tokens in context, so you get exact resumes with trivial storage. If you need to save the cache, your storage reqs go up a lot Probably fine if running it yourself but hard at scale

I refuse to accept that chartreuse is green. That's a red color's name
021
Dan @handackett.bsky.social · 03/10/2026
This would mean you can't resume state exactly without keeping the actual cache around, vs just the transcript

We are all trapped within/out this Klein bottle together (and also all the other ones)

Dan @handackett.bsky.social · 03/10/2026
Strictly speaking, because they are non-orientable, there is no sense of inside/outside of al Klein bottle

What is strand
110
Dan @handackett.bsky.social · 03/10/2026
Updated opinion: torus and orb are slightly different games because on torus you have two distinct fronts that you sometimes need to switch back and forth between. Klein and torus still functionally the same, I think
110
Dan @handackett.bsky.social · 03/10/2026
I guess you could have non-planar adjacency graphs, which is what falls out naturally from higher-dimensional minesweeper, but that seems like a UI nightmare
110
Dan @handackett.bsky.social · 03/10/2026
Agreed. I think what functionally changes/improves this versus standard rectilinear minesweeper is that the local adjacency graph varies. I wonder if there's any other generalization that similarly makes it more interesting; different manifolds are fun but I don't think they're changing the game
220
Dan @handackett.bsky.social · 03/10/2026
Okay that actually made the game significantly easier, or at least feels easier to play even if my empirical win rate isn't going up Also: I'm not sure Klein and torus are functionally different games, now that I've played them each

Dan @handackett.bsky.social · 03/10/2026
Oh yeah huh, that is definitely the right solution

This was going around Twitter today, if you ask Claude “is X lat Y long land or water?” and plot the results, it has clearly embedded a map of the globe in its weights over time

double torus minesweeper live, only really usable in the hyperbolic map view

Torusweeper and Kleinsweeper are live. It only reeeeeally works if you fix perspective and slip the game over the surface

How have you not asked for minesweeper on a time cool yet? Are you well

Dan @handackett.bsky.social · 02/10/2026
Careful; one is only really unambiguously inside the topology conference when all doors and windows are shut

Dan @handackett.bsky.social · 02/10/2026
As far as topology is concerned, everything is the same on either side of the process

I have no idea what you're talking about, but in response to earlier question: pants have two holes unless you unzip the fly, in which case they have three until you also unbutton the button

Dan @handackett.bsky.social · 02/10/2026
Maybe: I can take some shape and draw a bunch of nodes on it and draw edges between them. This defines a minesweeper. Topology is invariant as long as I only stretch and squish the shape, and never cut and sew. So I don't have to break any of the edges, and the game doesn't change, either

Dan @handackett.bsky.social · 02/10/2026
But actually it's because minesweeper is defined from an adjacency graph

Oops let's pretend you said number of holes and not Euler characteristic, both so my joke works and you have more sophisticated taste
