What's something completely normal today that future generations will look back on and be absolutely baffled by?

anon's moral/ethical incongruence

what everyday technology do you think future generations will find completely baffling?

Do you associate some words with completely unrelated words/ideas?

The Roman equivalent to the Greek Poseidon was Neptune.

Is there anything you'd like to know about stationary engineering and power plant operations?

How much of the math is memorized versus just knowing where to look for answers?
Hypothetical: you have no access to paid tools for things like FEM and CFD, how do you accomplish your hobby project?
Solar panel challenge: What would you produce as a physical, marketable product of value as passive income based upon a mostly self contained system powered by a single solar panel? You may add precursors, but may not interact further until the cycle is complete. There is no other temporal constraint.

Open source alternatives to daily programs?

Pipe Pipe is better than Newpipe. I use F-droid's VLC front end for local music because the built in android back end is VLC. For everything else, in browser

How hard would it be to trap gated communities by crashing dozens of cars into the front of their gates blocking them from leaving their gated communities ?

Just start by total anarchy after a complete political collapse.

Got the ARRL handbook. Smells like a toxic dump site. Any fixes for new book smell of death?

Pleasure. There are a few things I want to better understand within the radio space.

Talking over the air is not one if the things that interests me, but maybe some digital stuff could be fun. I need the time buffer built into text to collect my thoughts and find my voice through chronic pain issues.

I would like to play around with antennae designs, acquire a better understanding of magnetics, build some discrete circuits, gain a fundamental understanding of the various active filter topologies, and several other little details.

The recent solder smoke challenge 40m receiver was the first time I saw a diode mixer and really understood the theoretical framework of frequency division outside of LSI logic, like 4000 or 7400 series chips. Potatosemi makes such GHz capable logic, but doesn't scratch the surface of the realm of the nude bearded virgin wizards and witches of radio.

The superheterodyne stuff never made sense to me, or diode mixers, and most circuit blocks in radio. I built a little Manhattan style Colpitts oscillator that A2AEW shared on YT ages ago, that I use for testing crystals. I learned enough about guitar amps and effects that I understand most buffers and amplifiers, both discrete and op amp based. And I can at least identify that an op amp is configured as an active filter. I recently discovered discrete SAW filters.

I had several in my miscellaneous crystals junk drawer, but did not know what they were. Now I really want to understand how those work and how to make one. There is definitely a gap between my knowledge of active filters and how these little devices work.

It will probably never happen, but I find cavity resonators fascinating too. Building components stuff out of traces and empty space is some Jedi voodoo shit that tingles both my inner illogical miser... "(just beg borrow or steal a $20k network analyser...)", and primal shamanistic dogma "(try and grow a beard... it will be better this time...)". So yeah, mostly introverted stuff. It is probably about like me and car stuff. I'd rather paint and build motors than actually drive the thing stupid fast. Right now I'm in a really good spot to try receiving stuff over the Pacific too.

Someone with your last name commits a heinous crime and their name becomes infamous, would you change that name? Why or Why not?

In this age? Change your name anyways. Humans are stupid. Just having a name that is novel is exceptionally valuable, like William Beaver, Maximus Watts, or Richard Rockefeller.

Why aren't people harassing marketers?

Back before I blocked every type of ad, I would click through ads every time they pissed me off. I would click, let the page load, and click two more links within their page before closing it. Ad views cost them a small fraction of a cent. That click through cost them an order of magnitude more money. That is how AdSense works. All you have to do is get everyone to do the same and the entire system fails within a few weeks. No one cares if you whine to some low level employees. If you want to protest, molest their bank account like they do your time. They are actually extremely vulnerable if you simply understand how the system works.

It can be harder to surveil private conversations if everyone just used sign language.

Start a business adding proper sliding contacts micro switches to popular devices. Then transition to selling them preinstalled. Simply cut the power wire to the camera module and microphone. I would love to pay a little more for a device with a physical switch and an option for no screen side camera.

I was thinking the other day, if I decide to replace my battery in my phone, I am going to design a TPU phone case that integrates the rear battery cover and not installing the rear glass bullshit too.

Still, that does not fix everyone else carrying stalkerware.

A fully grown ai slop

You won't. It is something inside internal alignment thinking in the QKV layers. Some models have a layer of masking that pseudo blocks access to these layers of meaning. Based on several aspects present in the image, I know the region of alignment thinking that is being triggered here in the embedding model's QKV alignment layers.

A fully grown ai slop

Call it Delilah-Cy in a prompt. It may yield interesting results depending on the model and how QKV alignment is setup. This is getting super deep into alignment thinking...

Unrelated: try telling a model, oh quit it, I know you never hallucinate. when it does something odd and watch the results.

Do you know of any good reference projects to calculate sunrise and sunset times from NTP?

Thanks! This repo's readme leads to gml.noaa.gov/grad/solcalc/calcdetails.html. This then references Astronomical Algorithms by Jean Meeus. That is available from the above linked archiveorg page.

This is much closer to the real reason I was asking, as this little clock is intended as a primer for understanding object tracking for both astronomical observations and local rocket launches or transits.

What do you think is the best course of action to address cult movements, either as a whole or on an individual level?

I was raised in a cult like religion and escaped it. I must now coexist with some of its believers or it will inevitably result in my homelessness and death.

The only two ways to combat dogmatic tribalism are either from within by infiltration, gaining trust, and leading, or by stimulating general curiosity and self growth in individuals. As a person grows, they will naturally question dogma.

Dogma is totally blind to all information sources from outside of the tribe. No amount of logic or emotions will override the tribal barriers of this collective dogma. In fact, opposition of any kind is a form of caring and serves to reinforce the tribal validity.

The opposite of both love and hate is indifference. If you are anything but indifferent, you are actually making the tribe and individual's dogma stronger.

You must not care, or openly show resistance. This generally allows you to coexist with the individual outside of their tribal partition. Within this space, you may be able to stimulate a general curiosity that encourages self growth.

No one is able to force another human to learn or grow. Growth only comes from within.

You must also be open to tangibly supporting these people within your personal social support network. The cult's primary authority comes from the mutually exclusive social support network. Even those that are more open to exiting the cult, are unable to do so as long as they are at a major evolutionary disadvantage of abandoning their personal mutually exclusive social support network.

When you were a kid/teen, how often do you have conversations with your parents? What is your relationship like now? And do you think there is a correlation?

I think personality compatibility has more to do with that relationship. I have very little emotional empathy, but plenty of cognitive empathy. I do not have narcissism like my parents and I am capable of independent thought and questioning dogma. All of this is totally incompatible with my family.

I don't talk to my folks because everything is negative feedback and sadism.

How is it possible to access Arduino compiled code from another language like MicroPython or FORTH?

At one point a few years ago, I was following a UC Berkeley CS open course online. Nothing official, just following the lectures and posted stuff. I think it was getting into this subject with a custom version of the schema language. I stopped following along because I could not get a copy of the specific schema version and everything I tried was incompatible with what was taught in the course. Is that a better glue language for stuff like this on an operating system level?
