What is a Calibrated Decision? Under my definition, calibration is the search for errors in measurement. And a separate decision rule is applied to that measurement.

I see little rigor and precision in the thinking and description around what this model does, much of what I see looks like slop these days...

PID control seems to be lacking overall, the control laws seem to be more basic. In particular, my unit waits until temperature deviation from setpoint exceeds 1C before cycling on. If I want finer control, there are a few options I can think of: 1. Spoof the temperature, add a TEC , heater, cooler or something to the sensor on the remote 2. Manipulate the controller buttons, change the setpoint down or up by 0.5 degrees so the unit kicks on after a 0.5 degree change instead of a 1 degree change 3. Spoof the temperature sensor itself, hack into the wiring with some transistor based circuit 4. Hack into the actual unit, fully take over the compressor and fan control 5. Buy a better unit or off the shelf controller 6. Spoof the remote control, reverse engineer the IR communication temperature signal

This last option seems the least intrusive and cleanest, I see other people have done it, it's definitely a lot of work even with AI.

If so, you're right, the easiest way is to build/buy an IR blaster module for a microcontroller (ESP32 if you want wifi) and connect a temperature sensor. HA/EspHome is overkill for this, but can be useful for the large catalog of pre built integrations. Most of them are built using/on IR libraries for 'Arduino' anyway, so you can easily roll your own with a half dozen lines of C++.

Mapping out your own PID correction algorithm (esp says the room is 72 F when it's really 70 F to get it to cool sooner), but usually just having the remote room temp sensor near where you'd be sitting instead of near the ceiling or in the return air stream gets you close enough.

My biggest worry is the heat from the microcontroller affecting the temperature on the temperature sensor. I want to use a Sensirion SHT45, it has 0.01 degree temperature resolution and is supposed to be accurate to 0.1 C. But I need to locate the temp sensor far enough away from the microcontroller to make the overall remote controller form factor awkward. I have a Raspberry Pi 4 that does the temperature data logging and web server, but that runs pretty hot.

I want to do this but I'm worried about stressing the compressor with extra start/stop cycles would shorten its lifespan. Maybe they are programmed to overshoot/undershoot the set temp to prolong lifespan?

Disclaimer: I know next to nothing about how ACs work beyond the very basics.

Short cycling would be bad in the sense that the motor frequently turns on. The maximum current is during motor start and the maximum motor coil cooling is when the fan is running at high speed steadily. So if it starts a lot and doesn't run much at high speed you might tend to overheat, sure. That would definitely drastically reduce the motor lifespan.

If you are still starting periodically and running for awhile, you can see where this goes.

I think it's not overshoot/undershoot that is happening so much as delayed kick on.

That said, it's still a mechanical device that can experience stresses caused by cycles. Refrigerant systems also deal with gas/liquid phase changes and high pressures, so most units I've worked with do have a compressor lockout timer that allows a few minutes for temps/pressures to stabilize before kicking the compressor back on.

And hopefully that solves it?

Brigading is where a bunch of people on a forum team up and try to achieve a shared goal together. Someone shares progress and others build on that progress. On the Internet, I think it's not often used for good purposes. A good example would be: Taylor Swift fans on a forum thinking of ways to get revenge on Kanye. It's coordinating mass voting, DDOS type actions, commenting on social media, making more fake accounts to do that. As a next token predictor level analysis, a simple naive explanation is that the agents got stuck in that local minima/maxima.

I am sure about few things, but it seems to me that monotheism and religious exclusivism at some times represent the worst aspects and outcomes of religious faith.

Aircraft carriers are to a small extent superseded in their own right by strategic bombers and ballistic missiles. We may see nuclear aircraft carriers eventually superseded to some extent by missile/drone swarms and missile/drone deployment platforms, or some other threat.

If the new dominant technology, military in the sense of being used to dominate your adversaries in any arena, relies on data centers, is that infrastructure considered pretty robust? Will that data center infrastructure fully supersede the nuclear powered aircraft carriers, as has been done to battleships? Do hardened data centers and the software they run represent the main locus of national front line capability? Are AI researchers more like WW2 pilots, or are they more akin to the people who worked on the Manhattan project?

This post makes me think harder about physical computer infrastructure. Continuing the metaphor, silicon fabs, computer manufacturing supply chains and their related infrastructure are certainly the WW2 drydocks of our modern conflict, the WW2 drydocks having been critical for the Americans to churn out aircraft carriers. And the drydocks were only one piece, but might have been considered one of the most brittle.

Some seemingly brittle pieces of AI/data center infrastructure today are the fabs and the communication links. As far as I know, the fiber optic cables connecting continents are so exposed it's almost ridiculous, the cables lay directly on the ocean floor. If severing these links favors one or another global actor, my main question is why hasn't this already been done? You can ask the same questions about severing oil pipelines and the various global shipping chokepoints. I do wonder if fiber optic cables are defensible at all in the final analysis. And what life would/will be like without fiber optic connection between continents.

I'm not sure how much more durable satellite links are, due to the cascading debris effects of Kessler syndrome.

A key idea is that if the transoceanic communication links between the Americas and Eurasia were to be cut, either powers based in Eurasia or a power based in the Americas would gain an advantage.

Semiconductor fabs... Well, if I were a military strategist in charge of national security, I definitely wouldn't publish the location of every fab. And a a self respecting superpower wouldn't leave its EUV machine production external, or would it?

Fabless semiconductor companies and AI researchers are critical to current national security capabilities in the way that people who developed radar were critical to WWII. In the long enough term some people think that eventually data centers and the software running inside will supersede and encompass these functions. The question being increasingly not if, but when. Some people think that if it can be done by a computer, it eventually will be.

It really is all about timing, the Japanese thought the Pacific conflict with the USA would be short.

John, if the introduction of the translation of Book of Five Rings is so good, could you please share the identifying information including the translator or the person who wrote the introduction?

Mostly because it doesn't stay white and looks bad. But it doesn't stop people from painting their siding white, for example.

Why paint the sides of the rails? Well you can paint the tops, but it tends to gum up the wheels and get worn off.

You want a paint with high reflectivity and high emissivity. Just be sure you aren't using infrared light temp measurement as to measure and make claims about differences in temperature, emissivity is something to watch out for when measuring temperature in that way.

20 degrees is surprising, I sure wish my car was white in the summer.

I wonder if you have okay effects with white rails in the winter?

It's just polished, so that it is reflective.

If you sanded it with your 180 grit paper, you would get the scattering which appears white.

Tops of rails are already pretty shiny for any mainline track seeing a couple dozen trains a day. I'd bet they are more reflective than white paint could be. And the paint would be gone after the first train passes through anyways.

They rust pretty quick, but with regular use it doesn't build up much since it's constantly being worn off from the wheel friction.

Painting it cheeper than polishing. But I wanted to know the reason they needed to / that made it so.

Maybe my brain works differently than the author, but I'm surprised at this statement. Gym clothes don't change recognition for me, it's about the face, body, posture, clothes don't really enter into it. For me it is nonsensical enough to be suspicious.

And for a human centric perspective, not recognizing who someone is sad, it's knowing that you probably won't meet them again so it's not worth it, the community isn't there. Where community and interpersonal relationships between people are something we still hold dearly.

I'm a real person.

And I'm shit at recognizing people I don't interact with. PIcture 50 of us in black legging in front of a mirror...!

It is nonsensical to claim that anything other than my brain could produce the same consciousness that my brain is producing. It's obviously far beyond anything any conceivable digital computer could ever reasonably simulate, and even if you did create a "good" simulation it obviously wouldn't have the same properties that my brain does because it's an entirely different thing than my brain is.

An apology means a lot, I appreciate it. And hope that it can mean change.

“To the community of Tumbler Ridge,” writes Altman. “The pain your community has endured is unimaginable. I have been thinking of you often over the past few months.

“When I spoke with Mayor Krakowka and Premier Eby about this tragedy, they conveyed the anger, sadness, and concern being felt across Tumbler Ridge. We agreed a public apology was necessary, but that time was also needed to respect the community as you grieved. I share this letter with the understanding that everyone grieves in their own way and in their own time.

“I want to express my deepest condolences to the entire community. No one should ever have to endure a tragedy like this. I cannot imagine anything worse in this world than losing a child. My heart remains with the victims, their families, all members of the community, and the province of British Columbia.

I am deeply sorry that we did not alert law enforcement to the account that was banned in June. While I know words can never be enough, I believe an apology is necessary to recognize the harm and irreversible loss your community has suffered.

I reaffirm the commitment I made to the Mayor and the Premier to find ways to prevent tragedies like this in the future. Going forward, our focus will continue to be on working with all levels of government to help ensure something like this never happens again.”
