I think they might be computing the derivative of the temperature at time t in real time. When the schedule shifts to a higher set point the derivative goes to positive infinity and the system panics and calls for emergency maximum heat output.

They really ought to compute the temperature set point schedule for the whole day at once and then apply a low pass filter to that.

I’ve got it programmed in increments of a half a degree per hour. The thing still goes into panic mode.

Heat pumps are not simple at all. They are extremely efficient but can’t produce a large temperature gradient so they need to run very long cycles (potentially remaining on 24 hours straight). Modern cold weather air source heat pumps also tend to have variable output (variable speed compressor, variable speed fan). This demands a more complicated thermostat that adjusts the heat pump up and down, possibly with PWM.

And then there’s the emergency/auxiliary heating from the furnace. The thermostat needs to have some intelligent logic to decide when the heating demand exceeds the capacity of the heat pump and call for the furnace.

I have a heat pump as well as a furnace (for auxiliary heating). The thermostat frustrates the hell out of me! For one thing it loses its date and time (yes it has a full calendar date and time as well as time zone) if there’s even a single second power outage. How hard would it have been to put a CR2032 battery and a diode in there just to run the clock when the power fails?

For another thing, the thermostat itself runs extremely hot. Just putting my hand on it, it feels super warm to the touch. The LCD touchscreen on the other hand has molasses-slow response time. It’s almost impossible to set the temperature on the first try without overshooting by 2 degrees.

Lastly, it is designed to be able to run both the heat pump and the furnace when heating load exceeds the capacity of the heat pump. The thermostat also has a sophisticated time of day temperature set point schedule system (with separate schedules for every day of the week). However, the damn thing does not correctly reconcile these two facts!

I have the system set for cooler temperatures at night and warmer temperatures in the day. When the morning arrives and the schedule hits the higher day time set point, the thermostat suddenly sees a multiple degree deficit vs the set point and then calls for emergency furnace heating because it thinks the heat pump is failing to meet heating demand!

This is so maddening and stupid! Why can’t I have the temperature set point just continuously and cyclically vary throughout the day and night like a sine wave? No, the dumb thing runs the heating and cooling schedule as a square wave and therefore runs the furnace every single morning in order to slam the temperature up by a few degrees to the day time set point instead of gradually ramping it up over several hours with the heat pump…

Admittedly it’s very difficult if you want to maintain consistency but the benefits are enormous!

Persist everything to disk in real time. When the signal hits exit immediately.

Ahhh I probably get it over 500 for a big sear. Kinda crazy that my stove’s burner can get there even on medium.

That’s what led me to redoing the seasoning today. I washed up the grease with a few drops of Dawn and the pan came out with large areas of brown/white and dry/powdery rather than black and shiny.

I definitely have had the pan have a really strong seasoning that maintains a hard, glossy black finish even after washing with soap before. I’m hoping the current seasoning holds up a bit better.

I think maybe sometimes I burn the seasoning from cooking with too high heat? I really love to put a good sear on a burger or a steak and I love how cast iron is like a deep cycle battery that can store and release a large amount of heat into a piece of food.

I just reseasoned my 12” Lodge today! A lot of nasty smells coming out as I took off layers and layers of old seasoning with barkeeper’s friend. But now it has a non sticky, glassy smooth new sunflower oil seasoning. Very slick!

Does anyone know how to avoid having bacon foul up the seasoning? Seems like it always reacts chemically and incorporates proteins into the seasoning which make it nasty and dry and flaky rather than smooth and glassy.

I see this everywhere. Memes that assume millennials are 18 rather than 40. It’s become a meme in itself to troll millennials by deliberately conflating us with younger generations.

Racist narratives? Seinfeld has some episodes based on racism. The generally fall into two forms: making fun of racists and having one or more of the cast get accused of racism and hilariously try to prove they’re not.

If anything they’re making fun of the way the label of racist is impossible to get rid of once you’ve been tagged with it. It’s like being committed to a mental hospital and then trying to prove that you’re fine so they should just let you out.

Tankies might as well be called CINOs — communists in name only. Their defining feature is reverence towards authoritarian leaders. They revere Putin and Xi as “strong” leaders and completely ignore how little their regimes have in common with the socialist workers paradise Marx envisioned.

We disagree on what these words mean. There’s no further progress to be had here while that impasse remains.

I didn’t say they were irrelevant, I said they’re tools of survival. They’re obviously useful. People without any emotions at all just sit there with what looks like a catatonic state.

But being a slave to your emotions is nothing to aspire to. Far better to pick the emotional states you want to have. For me it’s enjoying deep focus on a task, having a lively conversation, sharing a great meal, laughing at a great joke, or cheering on a great play in sports.

Being a slave to your emotions is like being a ship tossed about on stormy seas. Emotional regulation is a skill that must be learned like any other. We’re supposed to teach it to young children, though increasingly I find myself meeting adults who don’t even have the basics down. People screaming at each other like angry birds!

The tougher one of course is learning how to overcome depression. That may need different strategies for different people. Mindfulness works for me but maybe not for everyone.

Well I was making a math murder joke!

I was just making a math joke!

Well we can, but only if there are an even number of people in the world. Otherwise there will be one person left!

Survival. The emotions are ultimately just crude tools the brain and body have for promoting the survival of the person.

Their crudeness is probably best illustrated with phobias.
