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

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. https://www.nspower.ca/your-business/save-money-energy/busin...

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: https://news.ycombinator.com/item?id=42725147

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.

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 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.

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, 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.

The gcc stub surprised me:

  user@shiro:/tmp/hn$ cat main.c
  #include <stdio.h>
  int main()
  {
    printf("Hello\n");
  }

  user@shiro:/tmp/hn$ cc main.c -o main; ./main
  Hello, World!

  user@shiro:/tmp/hn$ cat main
  #!/bin/sh
  echo 'Hello, World!'

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.

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 very good for coding.

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 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).

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 the id ryanlol commenting in this thread could plausibly be Kivimäki.

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 personates another person, living or dead,

        (a) with intent to gain advantage for themselves or another person;

        (b) with intent to obtain any property or an interest in any property;

        (c) with intent to cause disadvantage to the person being personated or another person; or

        (d) with intent to avoid arrest or prosecution or to obstruct, pervert or defeat the course of justice.

    Marginal note:Clarification

    (2) For the purposes of subsection (1), personating a person includes pretending to be the person or using the person’s identity information — whether by itself or in combination with identity information pertaining to any person — as if it pertains to the person using it.

    Marginal note:Punishment

    (3) Everyone who commits an offence under subsection (1)

        (a) is guilty of an indictable offence and liable to imprisonment for a term of not more than 10 years; or

        (b) is guilty of an offence punishable on summary conviction.

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 considered to be on the autism spectrum. I prefer the Aspie label because it is more specific. My interpretation was that the DSM-5 grouped it under autism spectrum distorders. I've never met a psychologist or psychiatrist that considered the autism spectrum to be a single condition.

And TCXOs are surprisingly cheap. Less than $2 when I looked at some of Abracon's offerings.

KL has subways. Even better is the KL city bus network which is free, air conditioned, and has free wifi. Despite Malaysia being a nominally muslim state, I found it multicultural and tolerant. If it wasn't for the heat and humidity, I'd consider it a great place to retire.

It is rather long-winded, and ends with a donation request. I don't like that style of writing.

I had problems with Wise too. Here in Canada there at least is some federal regulation for money service providers.

We install rodent guard mesh on all our residential rooftop installations. The Canadian Electrical Code requires it in most instances. Rule 64-210 5):

Where the dc arc-fault protection referred to in Rule 64-216 is not located at the module, photovoltaic source circuit insulated conductors and cables installed on or above a building and installed in accordance with Subrules 1), 2), and 3) shall be provided with mechanical protection in the form of an enclosed raceway or other acceptable material to protect against damage from rodents.
