I think so, yes. That's the main purpose of RTK

I think this is clearly a matter of preference. Shorter variable (or rather, appropriately short variables for the context) for me are easier to recognize and disambiguate. They take up fewer tokens, so to speak. When I see `p.Age` I don't have to go back and look at the beginning of the loop because I just read that line and I remember it.

I'm actually quite interested in your N paragraphs about why the category is written the way it is, and especially about the principles under which it is (or was meant to be) effective..

Frankly it's something I've always wondered about, but as mostly a spectator of these kinds of discussions I've never seen anyone explain. Like a lot of folks, from my surface-level knowledge it seems arbitrary and likely meaningless. But so much so that it feels like I must be missing something.

Or any chance of a link to your previous cpmments on the topic?

I could imagine that in practice you end up with a bunch of vulnerable people submitting themselves to experimentation by powerful companies, which is an unhealthy dynamic.

I believe this is required by code in some places, depending on the location of the switch. Mine is inset into the counter top, so plenty of opportunity for water to pool around it which I think would rule out an electrical switch.

I've always understood the increase in diagnoses to be more about increased awareness than about a change in human behavior.

E.g. it looks like autism wasn't defined as a spectrum in the DSM until either 1994 or 2000: https://www.spectrumnews.org/news/evolution-autism-diagnosis....

I have studied the properties of ketchup extensively at burger joints all over, and in my expert opinion Wikipedia has it correct here.

This is why ketchup barely flows when you invert the bottle, until you start banging on it and it gets moving and it all comes out at once (thinned by the shear stress of your banging and gravity)

I want something like this for accurate room presence detection in my house (for lights etc) that doesn't require dozens of PIR sensors or similar.

My dream is that the lights in my long hallway gradually dim up in front of me and back down behind me as I walk.

Summer breaks for teachers are much shorter than for students, especially when you take into account required continuing education and professional development.

It's also possible they they're correct, and the average user of today has much less need for verbatim searches than the average user when the search engine was first designed.

Many folks I know used WFH as an opportunity to move away from the city where you can get more space and quiet for less money.

Linked from the post: https://www.anfr.fr/maitriser/equipements-radioelectriques/l...

"These limit values result from the work of the International Commission on Non-Ionizing Radiation Protection, ICNIRP. In 1998, the ICNIRP ruled in view of the state of available scientific knowledge and only retained the proven effects of exposure to waves, in particular the heating of tissues."

The regulation specifies a test that measures frequencies up to only 10GHz, which is far below ionizing radiation frequencies.

I've always used ncdu for this. It also allows deleting files/directories for when you're trying to figure out how to free up space.
