The new(ish) Caseta paddle switches are pretty indistinguishable visually from normal paddle switches, and operating them is natural even though they don't stay toggled up and down. If that's the sum total of my concession to "these switches are smart", I can't say I care.
rpearl··on Writing documentation for your house
I put in a bunch of Caseta smart switches. They are indistinguishable from normal light switches without any smarts, but if I want to, I can also control them via local network. It's nice to go to bed and turn off the entire house with one button. Lights turn off automatically when we all leave.

The thermostat is an ecobee, which is a pretty polished IoT device but I'm frustrated i couldn't get something _more_ local. It speaks homekit so I can do a number of actions entirely locally, and if the internet is down it still works, but I do wish it were more self-contained. So again, if I sell or get angry at technology and chuck my HomeAssistant Pi out the window, the thermostat will just work as a thermostat.

Likewise, my blinds are motorized--but they have a working remote paired directly to them. It's incredibly convenient to raise the blinds in the morning for some sunshine automatically and close them after sunset, but they'd work perfectly well without a smart home.

If you purchased my house, you probably wouldn't even know to rip out the "smart home" components because they fail over to just being normal components.

It is not particularly hard to make this method of operation happen, although it admittedly requires a budget above "dirt cheap."

You appear to be arguing as if this was an axiom--cities are this way, and you struggle through it until you can leave. As if the goal is to make bank and leave the city. But this is the cycle, not the cause. It does not have to be this way, and in many places (many European cities, Japanese and Korean cities, and more) it isn't this way. Tokyo is huge, for example, and it is very much not "nightmarish". Nor London, or Paris. Certainly in all these places there are space tradeoffs, but that is very much different than the only reason to be there being to suffer through.

At least in part, cars cause American cities to be this way. Cars are too big for city streets; cars push people out of cities at night making for different concentrations of activity, and so on. This article is a decent enough jumping off point, top of mind because I read it literally today: https://thedeletedscenes.substack.com/p/keep-on-trucking

I believe we can have liveable, walkable cities, and it has nothing to do with "spreading out business activity".

The problem to be solved in this case is unnecessary distress and pain about one's inevitable death.
rpearl··on Psychedelics researcher approached his death with calm and curiosity
The paper you linked does not say what you claim it says.

Instead, it appears to investigate psychoactive drug deaths not to do with overdose.

There appear to be no "traditional" psychedelics (serotonergic hallucinogens like LSD, psilocybin, etc) covered here _at all_ except perhaps one death categorized as a "hallucinogen", which is definitely a lot less than 100% of the 147 deaths investigated.

rpearl··on AI 'breakthrough': neural net has human-like ability to generalize language
I don't care to pay for access to gpt-4 but one could easily use one of the vocabulary estimation tests, which use some statistics plus knowledge of word appearance frequency, to estimate its vocabulary size. https://mikeinnes.io/2022/02/26/vocab is one such test which explains the statistics ideas, and there are many others based on similar principles.
rpearl··on AI 'breakthrough': neural net has human-like ability to generalize language
let's see...

English speakers tend to have a vocabulary of 30k words or so depending on what exactly you measure.

GPT-4 has 1.7 trillion parameters.

Of course scaling up is quite unpredictable in what capabilities it gets you, but It's not that much of a stretch to imagine that a GPT-4 sized model would have a reasonably sized vocabulary. Certainly worth testing if you have the resources to train such a thing!

rpearl··on Advent of Code 2023's new AI/LLM Policy
Computers completely dominate humans in, say, chess. A game between humans is still interesting, though--and isn't nearly as interesting if one person cheats with an engine.

In the same way, a human competition in advent of code is an interesting challenge--and wouldn't be, if people cheat with AI solvers.

You can also temper chocolate by melting it to 50°C-55°C, cooling it to 28°C and then working with it, barely melted, at 31°C. I don't know how we figured that out to start with though.

rpearl··on Why don't we get our drinking water by taking salt out seawater? (2008)
Cool! Showers are 2gpd minimum, so if you think someone is likely to take a longer shower then you should definitely agree that 82gpd is not "wild", per the post I was replying too. Glad we're in agreement, and thanks for being so polite!
rpearl··on Why don't we get our drinking water by taking salt out seawater? (2008)
https://www.sdu.dk/-/media/files/om_sdu/institutter/iti/fors...

This study found these uses for indoor residential use: 18 gpd toilet (~10 flushes), 15 gpd washer (~1 load every few days), 11 gpd shower (~5 minutes), 11 gpd from faucet (~5min of flow, this one surprises me), 9.5 gpd from leaks, 1 gpd dishwashing

that's 65gpd right there. A ten minute shower and slightly more frequent laundry would easily get you 82gpd on indoor use only, ignoring any irrigation / outdoor use.

Is that wild?

evidently the airline priced that resource at a negative value. (Florida to Charlotte $X, Florida to Charlotte to NY $X-$Y.) so apparently that resource was worse than useless.
rpearl··on Are the Americans Awake?
The SI definition of a second, available at https://www.bipm.org/documents/20126/41483022/SI-Brochure-9...., section 2.3.1, does not reference our particular planet, nor any particular means of measurement, nor does it have to.

In principle this frequency can be measured in any inertial frame. Seconds are not defined on Earth specifically.

rpearl··on Are the Americans Awake?
A second is defined to be exactly the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.

I don't see anything referencing any planets?

rpearl··on Cooklang – Recipe Markup Language
Pretty much every recipe written since literally the 1890s / Fannie Farmer already has pulled out ingredients and quantities into their own separate section from steps.

To use cooklang, it appears that I have to rewrite recipes to include ingredients inline. No other recipes tend to use this style, because it is harder to read.

If I write recipes in cooklang, the plain text of the recipes is harder to understand without tools that speak cooklang, forcing me to use the tools to get an understandable format. The output of the CLI tool seems like a better format than the format itself!
