• The gold standard in the statistical analysis of scientific data is a p-value of 0.05. Never mind what it means. It is the threshold people use to say the result did not occur by chance. There is a wide consensus. Nearly all experts treat it as the bar to statistical significance. I am quite certain that most do not know what it means or where the number comes from. Never mind that. In principle, it means that if you redo the experiment, the result should hold. At least, that's what most people hope when they hear that a result is 'statistically significant'. It often will not. If the origina…
  Quoting@robinhanson!!: "A finding with a p-value of 0.05 has an expected replication probability ranging from 0.10 to 0.25 across fields."

• Unexpected Codex use case: set up an Android handheld for me. @johnvoorhees got me into this: enable USB debugging and just let the agent rip. Codex installed Cocoon frontend on my AYN Thor, transferred all my ROMs, and is currently configuring emulators, mods, and other apps. It's just working in the background and cross-referencing YouTube/Reddit sources to set everything up, so I can focus on cooking for the family instead. Incredible. @dimillian

• Reddit blocks VPNs. Reddit also now blocks old.reddit unless you log in. But apparently reddit offers a Tor service? And old.reddit still works fine there? (At this point I only check one subreddit, itself a shadow of its former self.)

• Bought a broken Grizzle-E duo charger on ebay, assuming I could probably figure out how to fix it. The problem was that it was missing the cable between the two boards. Asked @UnitedChargers support for info on how the pins on the two boards should be connected, or to buy a new cable to connect them. They wouldn't help, so a guy on Reddit took photos of his for me. Three wires later and it works perfectly and I can charge both EVs at once.

• This might be blasphemy over here, but to support longer/deeper discussions on Mastodon, I think it'd be nice if Mastodon would implement options for non-chronological lists of posts, e.g. similar to reddit's default 'hot" view. Could be as simple as sorting threads based on most recent reply. This could be opt-in and can co-exist with the current chronological view.
