Lately, HA has focused on voice control, and there seem to be a strong push that yielded some tangible results.

I don't use it myself, so I don't have first hand experience.

But the web site now has a section on voice control.

And there was blog post on it too.

If you search Youtube, you will find people implementing the above too.

because careering neutrons leave no trace of their activity behind

It's always this. Neutrons are "the little MBAs" of the subatomic world, and they chew through role after role so quickly that it can be dizzing to trace. Compounding the issue is that most subatomic particles don't take the time to fill out their LinkedIn profiles.

I am a Home Assistant user for at least 8 years.

Initially, it was for automating a few things, including existing door/window sensors from a legacy alarm manufacturer. Using RTL-SDR and rtl_433 I was able to intercept the messages, have them decoded, and into Home Assistant over MQTT.

Then it started to be essential for things like: if you leave a door or window open for more than x minutes, it will complain, unless you turn off that automation temporarily.

Now it does many things: Outdoor temperature, humidity, wind speed, wind direction, and rainfall. Indoor temperature, humidity, Volatile Organic Compounds, CO2, Radon.

It also emails me a weather forecast in the morning and evening. The contents are aggregated from the weather station, and two different sources for the forecasts (Environment Canada, and Met.no [Norway's weather service which covers the globe]).

It also runs my humidifier in winter, factoring in the values for indoor humidity as well as outdoor temperature (to reduce condensation on the windows).

And it interfaces to my Ecobee thermostat, via HomeKit, so it is cloud-free (not depending on an internet connection at all).

Overall, it is a nifty project. Very useful, very customizable.
My only gripe is that they discontinued support for running from a Python venv. I had to move to a Docker container instead. That made certain things that I have been using for years not work anymore (e.g. voice alerts, sending emails from shell scripts). I created workarounds for those, and they work well.

Last I checked Ruby execution was slow compared to Python. That, however, tells you where you shouldn't use it, not *that* you shouldn't use it. And Ruby can easily call C routines (with the usual caveats).

OTOH, in some task spaces, design in Ruby is fast compared to design in Python, and in almost all it's fast compared to design in C. (That said, I generally prefer to design in Python and then re-implement in C++.)

Whether it's serious or not depends on what you're doing. For me it fails only because I require Doxygen compatibility. (Mind you, I would rarely choose to use *only* ruby, but for some things it would be the superior choice.)

OTOH, Ruby is not a low level choice. It's a slightly higher level than Python. And I often design things in Python and then convert them to C++ (with, of course, minor rewrites).

So, "What do you mean by 'serious'?".

Submission + - Trump stuns auto industry with tiny-car move that promises ultra-cheap wheels (dailymail.co.uk)

President Donald Trump says he's moving to legalize Japan's beloved kei cars — the tiny, boxy, almost toy-like vans, trucks, and coupes that have a cult following overseas. And he wants US automakers to start building them here.

This makes a lot of sense in urban settings, especially when electrified. Hopefully these are restricted from highway system.

Remember that models used from a decade or more ago always make simplifying assumptions, and that those tend to be unquestioned until data shows that they must be. Even now climate models can't handle all the variables known to be needed. Turbulence is *extremely* difficult to handle. And there probably is some "butterfly effect". The way that's normally handled it to run an ensemble of models with slightly different conditions, but they may all make some of the same simplifying assumptions.

Well, panspermia is possible, but not extremely likely. OTOH, if life started on Mars, it could well have spread to Earth on impact debris. The further away, the less likely. But remember that yeast have survived in space conditions for months, perhaps years...and that wasn't in extreme cold (though it was in inactive form).

OTOH, years is different from centuries. And for interstellar trips in a comet, centuries wouldn't be enough.
