You could get a dev board and a breakout board on aliexpress for less than $6 - this way you can get away without any soldering for most use cases. And if you use esphome and homeassistant, pretty much all code is just configuration and setup in homeassistant.
That's a good bout of nostalgia - almost felt like watching an episode of Halt and Catch Fire. Joel, PG and Steve Yegge where some of the influential writers of that time who seemed to have a big impact on how people thought about careers, startups and corporate life.
So if I understood you and the original paper correctly, this observation is not in conflict with the Standard Model or Lambda-CDM and that this is an observational outcome of general relativity. Is that a correct statement? If so, then those models may need to incorporate why this may have happened, right?
Edit: Thank you for the detailed post. Learned a few things from it.
It's support for \Lambda-CDM, which is the standard model of cosmology. The standard model of particle physics is only involved to the extent that it explains spectral emission and absorption lines in the first place; locally the physics of electromagnetism vs hydrogen ions (among others) works the same over-there-back-then and here-and-now.
Sorry that there's two "standard model"s. One often hears "concordance model" or "standard cosmology" or \Lambda-CDM instead, as a result.
This study's novelty is in showing that [a] the changing luminosities of both families of variable quasar can be usefully compared and [b] similar variable quasars have similar luminosity-changing rates at similar redshift; if the redshifts differ, the less-redshifted one's brightness changes more frequently and more quickly.
It was surprising to come across an article on geological or planet-scale phenomena that did not mention human activities as a contributing factor to the changes being discussed. Effects of Anthropocene are still only skin deep.
The damage obviously goes beyond humans (for example coral reefs are getting decimated), but it's true the planet has endured far greater assaults in the past, and life has marched on. Environmentalism is Humanism in disguise. The risk is that we'll soil the crib and turn the planet into a hell-hole for future generations of humans.
A few years ago, we were building somethings to integrate with multiple expense and invoice management systems. Concur's odata based APIs were by far one of the worst integration experiences I had. (Even worse than integrating with dot net SOAP APIs from AXIS and Java)
You could see that some of the older APIs were well documented and thought out and the new versions were considerably worse. What we realized was that the earlier versions were built prior to SAP acquiring Concur.
That's "relatively" easy to do. Get in a space ship that could quickly get to a fraction of c, travel for a short amount of time and then return back to the starting point. You would have traveled to the future from the point of view of some one at the starting point.
This is actually harder to do in practice and is a common misunderstanding of the twin paradox, which is resolved by incorporating acceleration into the model.
