Ground source heat pumps absolutely do concentrate heat. See e.g. https://edwardsroyalcomfort.com/how-warm-does-geothermal-hea..., typical ground temps are around 60F and system output is above 100F.

> You’re just moving it down the entropic slope/dissipating it.

Agree on this, however

> In geothermal, you aren’t concentrating shit.

This one is a matter of opinion depending on scope so I'll disagree. You are concentrating it where it's useful. But overall system entropy goes up.

I quote:

>That is not what ‘power source’ means. You probably want to read up on some thermodynamics and definitions. I’m guessing you think that if you connect the heat pumps output to it’s input, you’ll have infinite energy?

There is no answer in that whole comment to my question. However, you did answer it in the comment I am replying to:

> you pumped the energy inside and concentrated it a bit.

Yes! That's exactly right. But furthermore:

> You didn't generate more energy than you had before. You did make existing energy more useful for you, comfort wise.

This is exactly right, and it is also known as the first law of thermodynamics. [1]. There is no way to produce energy. Even with electrical generation from geothermal, we are moving energy and concentrating it a bit, as you say, just in different forms.

I think we evolved to hoard stuff while stuff was really hard to come by. But the industrial evolution and especially last century messed up all of that by throwing a glut of near free objects at us and many of us are just not that good at dealing with it.

> So ask yourself, if more energy came into your home than you put in from the electric socket, where exactly did the extra energy come from?

I notice you didn't answer this question.

> That is using the earth as a source of thermal inertia, not producing power off earths heat - unless you're going down pretty deep. Again, not power generation.

I get the vibe that your definition of "producing power" is electrical power generation. However the original argument is that there is energy being extracted that is not in the form of electricity.

The point of a heat pump is to bring more Watts of heat into the home than the electricity consumed. Otherwise you could just use a resistive heater and heat the home with electricity directly. So ask yourself, if more energy came into your home than you put in from the electric socket, where exactly did the extra energy come from?

How is it not an energy source? The point of a heat pump is to move more heat energy around than was consumed running the device.

Nit: yes, home geothermal is a power source, technically. But yea not in the way an electrical generation plant is.

coal or gas i would guess

> Now, they can afford to be shitty

I dunno, I think it's easy to forget just how bad it used to be. I'll take "cheap junk" I can get off Amazon for a few bucks even today.

This makes me wonder, if you can replace one, can't you add one on top of the old one? Or two or three? There goes the range anxiety

It's all fun and games until it's a public school that implements the mandatory schooling law and so can't really kick out students unless they murder someone.

Way to bring up Linux power management into an unrelated discussion x_x

It's why I have a hard time watching some of the Gordon Ramsey shock cooking shows. He'll take a barely over or under-done filet and toss it in the bin to make a point. That's just not OK

This seems like just a purity spiral effect. What do you expect recruiters to say, that they hire medium engineers? I think this is mostly just performative

So much this. As I've been changing teams at my company (which by and large has awesome people) there is the occasional person in the team that just drags down the rest so much, they are probably a net negative. And it's such a breath of fresh air when the whole team is excellent.

I think something like we saw in the show "Devs" is much more likely, although what the developers did with it in the show was bonkers unrealistic. But some kind of big enough quantum device basically.

I recently saw this called a "purity spiral." [1]

I find primes spooky. They seem to be a concept that exists regardless of reality or universe. How does such a incontrovertible structure arise?

ps. Various numerology phenomena have a similar vibe, and no wonder so many people who go off the deep end tend to get trapped by them. Maybe I will be one of them as I become old and senile :-D

And yet, that's what you get when your software org comes from that kind of devops culture. And here we are

Neat! What's the hardware like, a Linux-ish computer with SD cards? Or SSD? Which filesystem?

Think of it as the scripts that run on CI/CD actions running unit tests. If a unit test fails, the test artifacts are uploaded to an artifact repository, and then, get this - the test runner instance is destroyed! But we don't think of that as unusual or nefarious.

I liked what flashed on the front page a week or so ago, about encouraging people to rant. With Slack specifically, it basically amounted to having a "<username-rants>" channel for every user.

Now that I read the current post, maybe that should be a Slack feature out of the box!

This has started to turn around in the US, and states like CA and MN require it, with MA to follow in a few days.

The problem is that if you don't use that dark pattern, you take a double digit revenue hit. So you revert to the dark pattern while shaking your fist at why the customers "just don't understand?"

The fun thing is that as long as you have the requirements and acceptance right, this could still be solved with a garage door opener and welded rebar :-D

Reminds me of early Google DIY rack PCs. [1]

It looked like something one would cobble together from a garage opener and weld together a bunch of rebar

> There are multiple ways to describe China's economy but the most accurate and relevant for this topic is that it's a command economy

That brings up an interesting point. It seems to be a conventional wisdom that centrally planned economies don't work (and did not work in cases where they were tried) as well as Western-style capitalism because of the communication and command bottlenecks.

But what if those bottlenecks have been greatly increased in the information age of Internet, other global communication networks, and data collection? The western-capitalist system has the problem of getting stuck in local minima, being driven as a network of actors. What if the downsides of that are finally greater than the performance hit due to central planning bottlenecks?

Grandma: Help me, Joey! After the neighborhood kid helped me install the coupon code app (he said something about expert mode, he is very smart!) my phone runs slow and crashes. :-(

Me: ...

You know how we got here? It used to be a free-for-all where grandma could download any software off the Internet on her Windows computer. You know how the rest went. I honestly don't mind it. It's so easy to recommend an iPhone to non-technical users, knowing the app store is still not compromised with low quality/malicious garbage. (Sure it requires a bit of expectation attenuation but the Android app stores are worse yet).
