Dataflow matrix machines (by Anhinga anhinga)

I am doing

ssh user@host

and it hangs. I need to Control-C it and try again, then I get a prompt for a password.

GitHub is having more and more troubles rendering Jupyter notebooks, and even the simplest notebooks sometimes require multiple reloads.

The alternative method of rendering Jupyter notebooks, via nbviewer.jupyter.org/

is also having the weirdest cache-related issues between it and GitHub (I was adding my complaints to github.com/jupyter/nbviewer/issues/979 in recent months on a regular basis).

WTF is going on? Is it that software engineers decided to pretend to be "effective managers" and are setting timeouts too tight and are invalidating some caches too fast trying to save some pennies?

From a May 26 meetup description: www.meetup.com/B-U-G-Boston-Unity-Group/events/278003882/

"Unity introduced the Scriptable Render Pipeline, along with LWRP, URP, and HDRP, each developed by separate teams that went in their own unique direction, breaking Unity into 4 different render engines and code bases with no cross compatibility.
[...]
These pipelines are in rapid development, and heavily-promoted by Unity, but are not well-documented. This talk will chronicle one man's attempt to get Unity to fix these issues, and finally give up and fix them himself."

A technology-optimistic forecast with a lot of interesting data. (The productivity curve flattening since around 2005 is stunning; interestingly enough, that curve has a good run from approx 1993 to approx 2005, mediocre between early 1970-s and early 1990-s, decent before early 1970-s.)

"solar, wind, and battery technology where prices have fallen 90, 70, and 87 percent over the last ten years": from www.agglomerations.tech/cracks-in-the-great-stagnation/

Space launch costs down to $2600/kg with Falcon-9 and $1500/kg with Falcon Heavy aerospace.csis.org/data/space-launch-to-low-earth-orbit-how-much-does-it-cost/

but I have not realized that the promise of Starship is closer to $10/kg ballpark. I don't know if that's believable, but the implications are stunning.

All this on the backdrop of our social misery: tech-wise we have nice progress, but socially we have rather impressive degradation: e.g. see how the emergency vaccination effort worked in 1947 compared to what we observe today: mobile.twitter.com/ComputingByArts/status/1350732240641290240

Who knows how this combination of potentially rapid technological progress on the backdrop of impressive degradation of social structures would work...
