The density of butter is reasonably close to 1 avoirdupois ounce per 1 fluid ounce, but is definitely not exactly equal:

https://kg-m3.com/material/butter gives the density as 0.95033293516 oz./fl. oz., or 0.911 kg/m^3.

(The link you provide doesn’t give a source; the data at the above link is sourced from the International Network of Food Data Systems (INFOODS).)

Further commentary:

The density of water (at refrigerator temperatures) is ~1 g/cm^3. 1 oz. = ~28.35 g; 1 fl. oz. = ~ 29.57 cm^3; thus the density of water is (1/28.35) / (1/29.57) = ~1.043 = oz./fl. oz. (This is, of course, equal to 0.95033293516 / 0.911, allowing for rounding and floating point errors.)

Note that the composition of butter varies. In particular, it varies by the ratio of butterfat to water (there are also butter solids, i.e. protein, but those are a very small part of the total mass). American supermarket butter has approx. 80% butterfat; Amish butter, European butters (e.g. Kerrygold), or premium American butters (e.g. Vital Farms brand) have more butterfat (up to 85%). Butterfat is less dense than water (thus the more butterfat is present, the lower the average density of the stick of butter as a whole—although this doesn’t make a very big difference, given the range of variation).

Given the numbers in the paper at the last link, we can calculate the average density (specific gravity) of butter (assuming butterfat content of a cheap American supermarket brand) as 0.8 * 0.9 + 0.2 * 1.0 = 0.92. This approximately matches our 0.911 kg/m^3 number above.

No, you’re misunderstanding. There is no 1/2 cup of butter anywhere in the above scenario. One stick of butter is 4 oz. of butter (weight), but not 1/2 cup of butter (volume).

“A space Odyssey” is not watchable without discussing historical context

… why? I’ve watched this movie, and I… don’t think I’m aware of any special “historical context” that was relevant to it. (Or, at any rate, I don’t know what you mean by this.) It seemed to work out fine…

The main problem with your approach is not that it is counterintuitive (although it is, and more so than ours!), but that there is no way to return to “auto” mode via the site’s UI!^[1] Having clicked the mode selector, how do I go back to “no, just use my browser preference”? A two-state selector with a hidden, ephemeral third state, which cannot be retrieved once abandoned is, I’m afraid, the worst approach…

Do you think a 3-state dark mode selector is better than a 1-state (where “auto” is the only state)? My website is 1-state, on the assumption that auto will work for almost everyone and it lets me skip the UI clutter of having a lighting toggle that most people won’t use.

Gwern discusses this on his “Design Graveyard” page:

Auto-dark mode: a good idea but “readers are why we can’t have nice things”.

OSes/browsers have defined a ‘global dark mode’ toggle the reader can set if they want dark mode everywhere, and this is available to a web page; if you are implementing a dark mode for your website, it then seems natural to just make it a feature and turn on iff the toggle is on. There is no need for complicated UI-cluttering widgets with complicated implementations. And yet—if you do do that, readers will regularly complain about the website acting bizarre or being dark in the daytime, having apparently forgotten that they enabled it (or never understood what that setting meant).

A widget is necessary to give readers control, although even there it can be screwed up: many websites settle for a simple negation switch of the global toggle, but if you do that, someone who sets dark mode at day will be exposed to blinding white at night… Our widget works better than that. Mostly.

Is it possible that someday dark-mode will become so widespread, and users so educated, that we could quietly drop the widget? Yes, even by 2023 dark-mode had become quite popular, and I suspect that an auto-dark-mode would cause much less confusion in 2024 or 2025. However, we are stuck with the widget—once we had a widget, the temptation to stick in more controls (for reader-mode and then disabling/enabling popups) was impossible to resist, and who knows, it may yet accrete more features (site-wide fulltext search?), rendering removal impossible.

(The site-wide fulltext search feature has since been added, of course.)

Not bad at all! Needs some work on the details and some bug fixes, but—really not bad! The dropcaps, in particular, are well done; and the overall theme is elegant.

I’m just going to link the comment I wrote the last time you mentioned that Rethink Priorities report. That report continues to be of very little use in supporting such arguments as you present here.

I in fact don’t use Google very much these days, and don’t particularly recommend that anyone else do so, either.

(If by “google” you meant “search engines in general”, then that’s a bit different, of course. But then, the analogy here would be to something like “carefully select which LLM products you use, try to minimize their use, avoid the popular ones, and otherwise take all possible steps to ensure that LLMs affect what you see and do as little as possible”.)

The most important thing is “There is a small number of individuals who are paying attention, who you can argue with, and if you don’t like what they’re doing, I encourage you to write blogposts or comments complaining about it. And if your arguments make sense to me/us, we might change our mind. If they don’t make sense, but there seems to be some consensus that the arguments are true, we might lose the Mandate of Heaven or something.”

There’s not, like, anything necessarily wrong with this, on its own terms, but… this is definitely not what “being held accountable” is.

It happening at all already constitutes “going wrong”.

This particular sort of comment doesn’t particularly move me.

All this really means is that you’ll just do with this whatever you feel like doing. Which, again, is not necessarily “wrong”, and really it’s the default scenario for, like… websites, in general… I just really would like to emphasize that “being held accountable” has approximately nothing to do with anything that you’re describing.

As far as the specifics go… well, the bad effect here is that instead of the site being a way for me to read the ideas and commentary of people whose thoughts and writings I find interesting, it becomes just another purveyor of AI “extruded writing product”. I really don’t know why I’d want more of that than there already is, all over the internet. I mean… it’s a bad thing. Pretty straightforwardly. If you don’t think so then I don’t know what to tell you.

All I can say is that this sort of thing drastically reduces my interest in participating here. But then, my participation level has already been fairly low for a while, so… maybe that doesn’t matter very much, either. On the other hand, I don’t think that I’m the only one who has this opinion of LLM outputs.
