Compared to my local utility (and most of Canada), the demand charge is low, but the per kWh charge is high. NSPower's general tariff is $9.089/kW + 15.738c/kWh for the first 200/mth, and 12.674c/kWh after that. Equivalent rates in Quebec and Manitoba are about half that.

Current CAD/USD is 0.7, so subtract 30% for NSPower's rates in USD.
My wife and I have a few rental properties that I manage. They are investments, chosen based on return on investment and equity (ROI/ROE). Maintenance costs were factored into those calculations. We take care of repairs not because our job is "providing the service of housing", but because we are honest and would not sign a lease (or any contract) in bad faith. When the lease says the property includes appliances, then we ensure broken appliances are fixed or replaced promptly. If/when we can't make a reasonable ROE on a rental property, we don't cut corners to squeeze a bit more profit out of it, we sell it and invest the money elsewhere.
First off, don't block the first connection of the day from a given IP. Rate limit/block from there, for example how sshguard does it.
I've seen several posts on HN and elsewhere showing many bots can be fingerprinted and blocked based on HTTP headers and TLS.
For the bots that perfectly match the fingerprint of an interactive browser and don't trigger rate limits, use hidden links to tarpits and zip bombs. Many of these have been discussed on HN. Here's the first one that came to memory:

I highly doubt there is no other technically feasible option to block the AI bots.
You end up blocking not just bots, but many humans too. When I clicked on the link and the bot block came up, I just clicked back.
I think HN posts should have warnings when the site blocks you from seeing it until you somehow, maybe, prove you are human.
Since you didn't show your math, I did a quick calculation. .45J/g/C specific heat of iron means .45MJ/tonne. 1811K to melt iron means 815MJ/tonne. 3.6kWh/MJ, so 226.4 kWh should melt 1t of iron.
Concrete mixes have become more complicated over time. Flyash has been around for a while, GU/L is relatively new and seems to set faster, often requiring retarders. Many different water-reducing additives are available. Air entraining agents tend to reduce strength. Fibers or steel pins added to the mix can improve crack resistance.
Batch plants will design mixes so some water can be added on site to improve workability. If you don't add water, the concrete will likely exceed spec.
A slump test is only one factor if many that impact concrete strength.
I know. AIKO has been using copper in their BC cells, and LONGi is making the transition. Many TOPCon cell manufacturers are using silver-coated copper pastes, but full copper metallization is unlikely to happen in the next year or two.
Panels prices bottomed about a year ago below many manufacturer's cash cost, and have gone mostly sideways since.

If silver stays above $70/oz, prices will likely go up by 5-10%.
Until Perovskite tandem technology matures, there's unlikely to be any significant reduction in PV module prices.
I'm intrigued. I'd like to see an analysis of how this was done. My first guess is they record humans doing the moves, and then map that to the robot movements. Then I'd like to see a teardown of one of the robots to understand their construction.
Are you saying Haiku is better than Sonnet for some coding use? I've used Sonnet 4.5 for python and basic web development (pure JS, CCS & HTML) and had assumed Haiku wouldn't be very good for coding.
Isn't "I know" just a subjective threshold for the probability of being true? A layman may put that probability at 90%, while I scientist may put the probability at 99.999% before saying, "I know".
I read "Thinking, Fast and Slow" and some of the other references in the article. I found Kahneman's arguments persuasive, however the article makes me re-evaluate those conclusions.
When asked what is more probable, I think in terms of statistical probabilities. However the article makes an interesting argument that most people don't define the term, "more probable" the same way. I'm not convinced Kahneman was wrong, but I do see how simple changes in the wording of a question can lead to a material difference in answers. I also see that my own interpretation regarding the "correct" meaning of words aligned with Kahneman, and contributed to my general agreement with his conclusions.
There's a lot of genes that impact lifespan, both good and bad. For example my father has hereditary hemochromatosis due to 2 copies of the HFE C282Y mutation. He was diagnosed in his 50's, so I'd expect the damage it did to his body to impact lifespan.
In my case I don't have it (I'm just a genetic carrier). If I did have the genotype and took the necessary dietary measures to avoid the phenotype, then it likely wouldn't impact lifespan.
On one hand you can argue a heritable disease like HHC has an impact on lifespan, but with genetic testing and treatment you can argue it doesn't impact lifespan (or it's impact is significantly mitigated).
