What kind of a blanket are you using and how thick is it? Seems like that would be the determining factor for size and cost.

baking··on Changes in schizophrenia diagnoses associated with cannabis use disorder
Schizophrenia develops in the twenties. Whatever his problem is, I don't think that is it.
baking··on Changes in schizophrenia diagnoses associated with cannabis use disorder
People develop schizophrenia in their early twenties. Once it develops, you have it for life. The evidence is that cannabis use at an early age makes people who are susceptible to schizophrenia unable to control it and it fucks up the rest of their life. Some people smoke a ton of pot and never develop schizophrenia. Some people who are susceptible to schizophrenia and wait until their late 20's to smoke pot or use it minimally before then are able to avoid schizophrenia.

This is a perfectly valid reason to avoid heavy cannabis use before the age of 25.

baking··on Changes in schizophrenia diagnoses associated with cannabis use disorder
Previous studies have shown that young adults who are susceptible to schizophrenia are more likely to develop it if they were heavy cannabis users at a younger age. As they get older it is less likely to develop, or they are better able to keep it from developing. My brother-in-law smoked cannabis in high school and college and was hospitalized for schizophrenia when he was in college. It wrecked his life and he still has schizophrenia at age 65. I don't think it is just an academic issue.
baking··on Vanguard's average fee is now 0.07% after biggest-ever cut
Dividends are built into the NAV price. It just becomes taxable income when it is paid out.
baking··on Vanguard's average fee is now 0.07% after biggest-ever cut
It's really annoying that people here are talking about "Zero" fee funds as if they were zero-fee funds. As far as I can tell "Zero" means less than 0.05% fees.

That's not how dividends work.

I just bought one for my nephew and sharing this with his piano teacher. Good luck and I hope you can keep it in stock through Christmas! ;-)
baking··on Toyota to buy clean power from a $1.1B solar farm in Texas
Found the typo too late for an edit:

$1.10B * 10% / 815000kW = $135

Just a reminder, the sun does not shine 24 hours a day.

$1.10B * 10% / 851000kW = $130

365 * 24 * $0.04 = $350

baking··on We Can Terraform the American West
The numbers in the OP show that the RO equipment is by far the largest cost so you need to maximize its utilization. The energy is used to pump water through the RO at high pressure so another alternative would be to use solar to pump water uphill so you could run the RO at night. The design using batteries is easier to price.
baking··on We Can Terraform the American West
So if I build a plant today to produce water at 22 cents per cubic meter, somebody could come along next year and build another plant that produces water for 15 cents and put me out of business. Then the year after that, another plant produces water for 10 cents, etc. You need 20-year contracts to sell water at a fixed price to make this work.

Raccoons and opossums have a good sense of smell. If you see holes in your yard you have (or had) grubs.
baking··on OpenAI pursues public benefit structure to fend off hostile takeovers
The nonprofit will hold stock in the BPC. I think the effect of this is that the nonprofit board, which is independent of Altman, will be restricted from selling their shares. However the nonprofit will eventually convert from a public charity to a private foundation and will be required to give away a percentage of their assets every year. I'm not sure how that will work with a BPC.
baking··on It's Time to Stop Taking Sam Altman at His Word
I think you are missing my point. Microsoft signed a 20-year agreement with Constellation to restart TMI Unit 1. Do you think Constellation would make the same agreement with Open AI? The risk is completely different.
baking··on It's Time to Stop Taking Sam Altman at His Word
What if it is a 5 gigawatt data center in the middle of nowhere or if the power source is a nuclear reactor or three? Presumably, data centers are paying a premium that other customers aren't willing to pay.

He is the Executive Chairman at Helion, which means he keeps a tight grip on that particular purse string.

>So if everything about this AI boom fails what we'll be left with is a massive amount of abundant renewable energy

Except that someone has to pay for it. AI companies are only willing to pay for power purchase agreements, not capital expenses. Same with the $7T of chip fab. Invest your money in huge capital expenditures and our investors will pay you for it on an annual basis until they get tired of losing money.

baking··on Solving climate change by abusing thermodynamic scaling laws
Eli Yablonovitch has been working on this for a while. I thought it was assumed that only the lignin would stay sequestered but I'm not finding those details.

baking··on OpenAI to become for-profit company
A non-profit can't give away its assets to a private entity, but it can exchange its assets for fair value, in this case, equity in the for-profit.
baking··on OpenAI to become for-profit company
The nonprofit gives all its ownership rights to the for-profit in return for equity. The nonprofit is free to hold the equity and maintain control or sell the equity and use the proceeds for actual charitable purposes.

As long as the money doesn't go into someone's pocket, it's all good (except that Sam Altman is also getting equity but I assume they found a way to justify that.)

OpenAI will eventually be forced to convert from a public charity to a private foundation and will be forced to give away a certain percentage of their assets every year so this solves that problem also.

baking··on Starlink U-turns, will block X in Brazil after all
I thought they had an office in Brazil and they threatened to arrest them, so Twitter shut it down.
baking··on Steve Ballmer's incorrect binary search interview question
I think you did the math wrong. The expected value for the guesser is $0.20 if Ballmer chooses randomly. I think Balmer is saying that he can beat you if he chooses adversarially and you choose the expected initial guesses.

I agree that if you choose your first guess somewhat randomly in the 40-60 range (maybe not a uniform distribution though) Balmer would be forced to choose randomly and you would be back at a positive $0.20 EV. For example, you could flip 6 coins and add the number of heads, then flip another coin to decide whether you add or subtract the number of heads from 50 for your starting guess. But I think you would need to randomize your later guesses a bit also.

baking··on Steve Ballmer's incorrect binary search interview question
You have 31 positive payout guesses (1 $5, 2 $4, 4 $3, 8 $2 and 16 $1) leaving 69 other numbers with zero or negative payouts. You don't want to have gaps larger than three between your positive guesses, but there are 32 gaps for a total of 96 possibilities, or an excess of 27 over the numbers you need to cover.

It seems like a lot of possibilities and I think you can get away with a minimum gap size of one, but let's assume you do 5 3-gaps at 1, 25, 50, 75, and 100 and 2-gaps everywhere else. So start with 51, then 26 and 76. Then go up or down 12, then 6, then 3. If you have a gap of two you flip a coin, if a gap of three you pick the middle one.

Or if you have them write down the number and you think it has double-digits you could put your 4-gaps below 20. Start with 53 and go up or down 24, 12, 6, and 3 (unless it is below 20, then it is multiples of four.) 59 would pay you a dollar.

Your starting guess could be anywhere from 37 to 64 without paying out more than a dollar, but if you start with an extreme, then low odd numbers and high even numbers will have a negative payout. However, I think you can still randomize sufficiently starting with 38 and 63, e.g. 63-31-15-7-3-1.

baking··on Blood pressure control should focus on more potassium (2023)
Long story, but if you are interested in potassium and high blood pressure, or if you have low potassium and high blood pressure, my story might be of interest to you.

At age 38 I was diagnosed with very high blood pressure. I had not been going to a doctor and was having headaches and bloody noses so it might have been going on for years. The first drug they put me on was a diuretic. They also put me on potassium after low potassium levels which is common with a diuretic.

Eventually, they also put me on a beta-blocker, a calcium channel blocker, and an ACE inhibitor. So I was getting all four BP meds and ended up at high or maximum doses. Around age 50 my potassium levels were getting very low and they kept increasing my potassium to no effect.

Primary care and cardiologist were flummoxed so they sent me for a kidney MRI. The radiologist looked at my history and decided to also check the adrenal glands, which sit on top of the kidneys so that was his call.

Turns out I had primary hyperaldosteronism which causes low potassium and high blood pressure. Not clear if it was the cause all along because I'm not sure I had my potassium checked before starting the diuretic. I saw a very good endocrinologist who had tests done to confirm the MRI and make sure that they removed the correct adrenal gland and then I eventually went down to a low dose of only one BP med.
