upgraded my eGPU setup over the weekend [RIP ADT rube goldberg machine] and decided to document it for posterity (with some promo for my torch econometrics package included)

My twitter feed is doing a 4th round of memeing a shitty inconsequential interview and my bsky feed is 4 people competing to be the goodest boy by circular firing squad. Back to whatsapp and discord then.

behold, an authoritative answer to the question of "how'd you like em apples?"

[also love how old papers have the most stilted hot-takes in their intro. no citation salute to the elders to get the paper accepted, just passive-voice passive-aggressiveness]

if you use a tiling wm, you can event tuck the radio away into your scratch workspace [L; omarchy makes it very easy]

compact htmx makes it work well on mobile [R] with background playback [getting it to not die on suspend was the most javascript i've had to learn].

Go play Crab Souls. It is so very good.
If AAA's want $100/game they need to be significantly better than what smaller / indie devs are making.

They aren't.

The most fun I had last year was Another Crab's Treasure ($30). Silksong this year was $20.

If the sit down restaurant is 4x the cost of the foodcart (& no better), I'm not sorry.

split keyboard recs? but like really really split; the wiggly phone cable thing won't do for obvious reasons.

Built and hosted a scrappy fasthtml radio player on a VPS for my own edification+excuse to listen to good radio (Soma, kexp, etc).
Curious how many concurrent users can use it before it crashes the tiny raspberry-pi tier machine i deployed this on.

watch palo alto shutter all three caltrain stations in response to SB79; atherton is already thanking its lucky stars it shut its only public transit.

[more seriously, is a potential second-order effect that this passes the buck to transit extension being monstrously difficult?]

Put stuff on arxiv, it'll have more impact than 90% of papers because the robots read more comprehensively than most of us. Gwern-pilled conclusion - write for the robots.

Apologies for the interruption in coverage; I have a good excuse, henceforth known as The Agent (of both the ‘defying the Principal’ variety and the fast-learning natural/artificial variety).

Acquired one of these newfangled learning agents. No API documentation though; time to figure it out by trial and error over decades.
