I have some of (possibly the?) cheapest residential electric power in the US, at 5.58 cents per kWh all-in cost here in Wyoming, 90%+ hydropower.

Absolute lowest cold here each year will be around -30 F / -34 C (there will be several nights in the winter where it gets below -20 F / -29 C), and absolute hottest it will ever be around 85 F / 29 C, but average annual temperature is about 35 F / 2 C. It can snow any month of the year here, with snow on the ground usually between November and mid May.

My house was built in 1968 and I have primarily resistive baseboard heating, with a large Mitsubishi mini-split installed by my home's previous owner mainly for air conditioning purposes in major rooms for a couple of weeks in the summer. I live at 6500 ft / 2000 m altitude, so even on the hottest summer days once the sun goes down it gets quite chilly and can get close to freezing, so it's really just for a few hours in the afternoon for a/c purposes. I otherwise use the heat pumps as baseline heat in the winter.

I'd like to put trust in heat pumps more because they are obviously more efficient (also as seen by my already low power bill), but lack of heat on certain days in the winter has serious implications here for home integrity, and while this might just be this one Mitsubishi model (though they are less than 5 years old), I haven't been left with a good opinion of heat pump design and repairability in general and am not tempted much to explore heat pumps further.

The heat pumps are rated to work down to -5 F / -21 C in the manual, but in practicality it's more like 15 F / -9 C otherwise they just spend a large part of their time defrosting. The models I have don't seem well engineered for reliability or maintenance either, there are important fuses hard-soldered to the main board that are not individually replaceable, and true enough in the middle of winter my HVAC technician and I had to bypass the blown fuses with an automotive fuse we had (same stats) attached with alligator clips, as it would take weeks or months to obtain a new $1500 (!) main circuit board from who knows where. On the other hand, resistive heating usually just works assuming you have power, and I also have two fireplaces as emergency backup if there's no power (though power lines are almost all buried here due to snow/ice anyways).

I really would like to see more emphasis on reliability and repairability rather than, like, SEER, HSPF, or COP ratings or whatever.

Why is everyone is so critical of using information from a previous model to make a more efficient model. There’s nothing wrong with making progress using prior work. And increasing efficiency is progress.

Only fools pay for healthcare with insurance. If a doctor can't convince you to pay directly, don't use his services. Find a better doctor and pay for it yourself.
How much do we need to progress before it becomes comparable in terms of energy to the (often already rather energy-inefficient) data pipelines we've been using so far?

Recall that while the cost per token may decrease, CoT multiplies the number of tokens by several orders of magnitude.
No, it extracts heat from the air in the basement. It cools the surroundings (assuming one is using the hot water, not allowing all the heat there to eventually diffuse out through the insulation, but a resistive water heat faces that same issue without having caused any cooling first.)
Do you really need a health insurance company's revenue/profits in absolute amounts to "start to ask questions" about the state of the US healthcare system? The fact that the US spends twice as much as its peers on healthcare should be enough justification.

Moreover, it's unclear how you make any meaningful conclusion from the UNH's absolute financial numbers. UNH makes $32.3 in profit on $400.3 billion of revenue. Medicare on the other hand spent 1 trillion (!). It's unclear how anyone can look at those numbers and conclude whether they're too high, too low, or whether "the absolute amount has been inflated".

Blogging is like all other content creation: the vast majority of the viewership goes to the top 0.1% of creators. This is the same whether you're talking about YouTube, Twitter, podcasts, OnlyFans, scientific papers, traditional books, etc etc.
The problem I have with this kind of bias evaluation is fairly straightforward: what if a group of people aligned in a particular way engages in more "untrustworthy" speech than their counterparts? Follows then that a filtering that aimed to curb untrustworthy content would now be disproportionately filtering against their content in general, so now they can point at the filtering and call it biased, and even pass the smell test as far as the numbers are concerned.

Very curious things start happening when we look through lenses like these. It's very difficult to effectively discuss unfortunately too, without getting into any catfights.
I’m in DC and my childhood home and both homes I’ve owned have had heatpumps.

They all have back-up electric heat elements that kick on when the heat pump can’t keep up. In our mid-70s build home (mediocre insulation and windows), that happens somewhere in around 15F. Basically a few nights/month in Jan and Feb. I can see the bump in electric bill when we have an unusually cold winter.

But, overall it’s not a bad system. Most of the time, it works fine. The one downside (vs radiant heat) is it can feel drafty. But that’s going to be true of any forced-air heat.

Anyway, sounds like you’re right on the edge of where a heat pump might be suitable, so you’ll need to talk to a specialist (or at least somebody else who’s used one locally). They’ve come a long way in efficiency and if it’s a new home, the better insulation will help a bunch too.
Username remarkably relevant. Clever troll account. Well played.
You can use GC defaults, but tuning can provide valuable throughput or latency improvements for the application if you tune the GC parameters according to the workload. Especially latency sensitive applications may benefit from generational ZGC in modern JVMs.
Yeah, LLM-generated images aren’t quite there for precise and consistent modifications, and they definitely don’t produce clean, vectorized results. If you want the laziest approach with the most control, here are some options:

1. AI-Assisted Sketching (Fast & Adjustable)
• Use an AI tool for rough generation, then clean up manually.
• Lazy Workflow:
1. Use tools like DALL·E, Stable Diffusion (ControlNet), or Deep Floyd IF to generate rough sketches.
2. Convert the image to a vector format using Adobe Illustrator (Image Trace) or Inkscape (Trace Bitmap).
3. Manually tweak lines to make them precise.

Pros: Speeds up initial drawing, retains some AI assistance.
Cons: Still requires manual cleanup.

2. Pose & Trace (Super Lazy & Customizable)
• Use a 3D model as a reference, then auto-trace or hand-trace.
• Lazy Workflow:
1. Use PoseMyArt, JustSketchMe, or Blender (with rigged models) to pose a 3D figure.
2. Screenshot or export as a line drawing.
3. If needed, vectorize in Illustrator/Inkscape.

Pros: Total control, precise angles, reusable.
Cons: Minor learning curve with posing tools.

3. Pre-Made SVG Libraries (Even Lazier)
• Find existing vector illustrations and modify them.
• Lazy Workflow:
1. Download from Noun Project, Freepik, or SVG Repo.
2. Modify in Figma, Inkscape, or Illustrator.

Pros: No drawing required, quick edits.
Cons: Limited flexibility, may not match style perfectly.

4. Procedural Line Art with Code (Automate It)
• Generate line drawings programmatically using code.
• Lazy Workflow:
1. Use Processing, Manim (Python for animations), or P5.js.
2. Script different poses and generate SVGs automatically.

Pros: Extreme consistency, great for tutorials.
Cons: Requires coding skills.

5. Vectorize AI-Generated 3D Renders
• Lazy Workflow:
1. Use RunwayML, Kaedim, or Blender to generate a 3D render.
2. Convert it into a line drawing with a Freestyle render (Blender) or vectorize it.

Pros: Consistent, reusable models.
Cons: Needs a bit of setup.

In general, I have found that blog posts have a larger impact than my conference talks. At a conference, say, with 100 people in the audience, perhaps only 20 find it relevant. With a blog post, we may feel disappointed that only 1,000 people read it — which is small by blogging standards, but still way more than one would reach at a conference.
This is not an original observation, but it took me too long to realize so I think it bears repeating: your personal website is also the one place where you have control over how much to write, how it looks to the reader and how long it stays up. Even though I'm a proponent of strict moderation on social media, it's ultimately a bad thing to hand over that kind of agency to the platforms.

Mean daily maximum in July and August in Utrecht is 23C/73F (compare to 30C/85F in Chicago and NYC). The Netherlands is further north and a lot more moderated by ocean temperatures - it's kind of like SF in that regard except the entire country has a similar climate so AC is not a cultural expectation.

How will these people mentally cope with the coming realities of having to trade their $300k comp (some of which didn't require a lot of work during their tenure) for making $80k writing CRUD apps and line of business software at some local shop 40hrs a week. The job market isn't great right now, not to mention oversaturated with programmers, it's not like they will all move over to Google tomorrow. Even if they have plenty of money, it's an ego hit to slash your comp by 2/3 just to stay employed. Not to mention they have the stink of layoff on them, even if you were a top performer it's the very first question recruiters ask incredulously. These people had a golden ticket but fell into the vat of chocolate.
Is there more information on this?
Obviously facetious, but I'd hope most people would want their blog post read by LLMs.

I suspect (hope) a lot of blog posts are written to share knowledge. In that regard having that knowledge trained in to LLMs (ideally open ones, but even closed ones) could further that goal.

On this topic I've been wondering why are the air-air heatpumps significantly cheaper than air-water units?

As far as I could tell, there's not that much of a difference (different heat-exchanger, circulation pump instead of a fan, maybe a three way valve for hot water)- but I have hard time seeing how they contribute to the price difference of several thousand EUR.

There are also quite a few conversion projects (where an air-air unit is converted to air-water), so I'm wondering if it really comes down to just higher demand for air-air?
Thanks for explaining the background of that.

I agree that human readability can make things somewhat easier. The part about a binary format for the signatures confuses me a little - the signatures are going to be big no matter what. If you care about minimizing size would it make sense to just find a more efficient way to encode the signatures rather than change the entire message format?
Sacramento is not “on the coast”, more of Central Valley, so it does get hot.

Where I live in the “Peninsula” part of Bay Area, we may “want” rather than need A/C maybe 1 week a year. My heating is provided by a 15 year old forced air gas furnace, but I’m in no hurry to install a heatpump because of our ridiculous electrical costs - thanks PG&E.

Our current rates seem to already average at $.5/kwh, probably 5 times more than the rest of the country.

I would wager that adoption of heatpumps is related to cost of electricity vs gas

In those scales (cosmology+Field Theory) energy is derived and defined as the "thing" that is conserved after you apply time symmetry.

Also you kinda want time symmetry in a physical system otherwise you have no guarantee that today's laws of physics will be valid tomorrow.
I get that sliding in references to a passion project on top-scoring articles might seem like an easy way to give the project exposure, but commenting the same thing over and over comes off as a bit boorish. And just plugging the URL isn’t really contributing anything to the discussions IMO. Why not show us something your tool explained or summarized from the articles that isn’t obvious from a cursory read? Citing the tool as the source for something cool wouldn’t be nearly as in-your-face.

Heat pumps are used extensively in Scandinavia, including up in the polar circle. These are usually ground source heat pumps, which is the essentially the same pump technology but connected to an in-ground loop instead of taking heat from outside air.

Nowadays the air con uses the same heat pump to extract heat from the house and pump it into the ground, which not only chills the house but also helps a little recharging the ground source.
Oh, lol, I had it backwards.

But in winter, when I’m using more hot water, the heater is cooling a house I’m desperately trying to keep warm? Not sure that’s any better. Is the amount of cooling noticeable? We’re in a small (by US standards), mid-70s home - it’s already next to impossible to keep the basement warm enough to use in January.
It's getting discussed here now:

Seattle is a great place for a heat pump. Depending on where you are, and your tree cover, most summer days are fine with windows open, but heat waves are icky. Otoh, below freezing is pretty rare, so most of the time, you'll be in the efficiency zone; on the big snow days, it's useful to move snow away from your outside unit to keep it working as well as it can in those conditions. Wall mounted units, common with mini-splits, probably don't have to worry about that.

Utility natural gas is available in some places in the region, but not everywhere... Heating with propane would be pretty expensive, IMHO.
In Netherlands we have a free market for health insurance, however there are regulations and pretty much all essential care is included. Also the insurance company is not allowed to reject any person. Furthermore, every person is required to get health insurance. So healthy people pay for the old.
I disagree. I write differently when I anticipate an audience (even if they never come).

Maybe parallel: I notice when, for example, I edit videos in my own world I have a very different take on the edit when I am showing it to someone for the first time.

Thinking to myself: "Now as I watch someone else watching it, I am become aware that this scene goes on a bit too long. This cut is a little abrupt, disorienting."

I didn't "see" those until I had an audience.
Based on some quick napkin math from their 10-K for FY 2023, they could afford to spend about 7% more in claims (107% of their current payouts, that is).

This is all true. The only part that is potentially misleading is that the target doesn't need to be a blog. A blog is a fine target, however. The key activity is spending time to articulate a message with enough clarity that another person will understand what you meant and that they will conclude there is some value in it. There are lots of avenues for this.

It's not limited to this, but in the workplace I think of this as "write it down culture". People who write things down often have the most tested and credible ideas, with the first and most important judge being themselves.
I regularly have conversations with people that end up with some form of "Let's not belabor this over beers but I'll send you a link to something I wrote. It may be a little bit stale but let me know what you think and we can follow up."

Blogging has internal benefits of organizing thoughts or even just being a fun hobby. But it's external validation as well. Sure, writing a book is even more but that's probably 100s of times more work.

This would be acceptable if it meant adding one more shader, but with "modern" graphics APIs forcing us to sometimes have thousands of permutations for the same shader, every variant you add multiplies that count by 2x.

We also don't have an infinite amount of time to work on each shader. You profile on the hardware you care about, and if the choice you've made is slower on some imaginary future processor, so be it - hopefully that processor is faster enough that this doesn't matter.

And I have PG&E so the economics of a heat pump don't pencil out. Gas heating is still cheaper than a heat pump because electricity rates are out of control. (Gas isn't cheap either but still cheaper)

California is doing everything it can to eliminate natural gas heating except for make the alternatives more affordable. PG&E and Socal Edison are basically given a bank check to keep raising rates by the oversight board. (Doesn't help that they are also burning down cities)

One important aspect I learned about blogging is that a post effectively "ships" a side project, deeming it complete. A blog post allows me to move onto the next thing. It is closure of sorts (glouw.com if anyone is interested in the style).
