Instead of cash, I like debt like mortgage funds. High single-digit returns with low volatility.

The article didn't include the actual power rates. I think the applicable tariff is $3.316/kW of demand + 16.82c/kWh. https://www.scc.virginia.gov/docketsearch/DOCS/89pc01!.PDF Com…

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 thos…

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 s…

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 bl…

HVDC transmission over 100kV lines are common now. https://www.emeranl.com/maritime-link/overview

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 m…

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…

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 meta…

Don't start with a 5MW project. Start with a 10-20kW ground-mount project in your back yard. Then build a 100-200kW project before trying MW.

Panels prices bottomed about a year ago below many manufacturer's cash cost, and have gone mostly sideways since. https://www.pvxchange.com/Price-Index If silver stays above $70/oz…

The gcc stub surprised me: user@shiro:/tmp/hn$ cat main.c #include int main() { printf("Hello\n"); } user@shiro:/tmp/hn$ cc main.c -o main; ./main Hello, World! user@shiro:/tmp/hn$…

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 se…

I'm using Sonnet with a free account.

The mouse is invisible on the splash screen, except for when I manage to move it over the play button.

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 ve…

Maybe it is just the HN effect, but it is really slow.

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 …

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 conclusion…

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 …

Julius Kivimäki was released pending the outcome of his appeal. https://www.bankinfosecurity.com/finnish-vastaamo-hacker-fre... The article cites "Ryan" as one of his aliases, so t…

Most residential 200A electrical panels use tin plated aluminum busbars. https://www.eaton.com/cr/en-us/catalog/power-connections/bus...

As a common-law legal system, I would expect Ireland to have something similar to Canada's Criminal Code identity fraud. 403 (1) Everyone commits an offence who fraudulently person…

I got my diagnosis shortly after the DSM-5 release but my psychologist also gave me the DSM-IV Asperger's diagnosis at my request. I tell people I'm an Aspie, and that it is consid…
