joshuahaglund··on Bring crypto back to currency
> Algorithmically, it is possible to control how much it costs to mine crypto at any point by modulating network fees (PoS)/block difficultly (PoW). This would in turn have an effect of the supply of the currency because if it becomes cheaper (in USD) to mine than more people will mine it (as it becomes more profitable to do so).

If it's cheaper to mine, it won't be more profitable. See dogecoin. It'll create more token and at a decreased value.

I can't believe people are still falling for this ponzi scheme

joshuahaglund··on Safe Superintelligence Inc.
I clicked, hoping that "human extinction" was just the worst thing they were against. But that's the only thing. That leaves open a whole lot of bad stuff that they're OK with AI doing (as long as it doesn't kill literally everyone).
joshuahaglund··on New gel breaks down alcohol in the body
One guy says it works. The rest of the article is about a small experiment that showed otherwise. Then it quotes experts who explain why it doesn't work and called it an urban legend.

joshuahaglund··on Thoughts on Seed Oil
Deep fryers are usually 175 to 190C so trans fats shouldn't be much of a concern. I'm more concerned about everything else about deep fried foods -- being high calorie, low nutrient, zero fiber. The choice of oil is irrelevant
joshuahaglund··on Hacking the genome of fungi for smart foods of the future
It does compete for water and cropland. And ethanol production is also a waste of resources
joshuahaglund··on Hacking the genome of fungi for smart foods of the future
> If you did read the scientific study I linked to, then you would now know that land that "food animals" occupy is often not at all suited for other forms of agriculture.

How much of a cow's diet do you believe comes from resources that would not be otherwise useful to humans?

Cattle farming uses most of the water in the west. https://www.vox.com/the-highlight/23655640/colorado-river-wa...

Your image of cattle grazing out on the range is out of touch with reality. Nearly all beef consumed in America starts with diverting water that could go towards directly feeding humans

We just consume too much beef

joshuahaglund··on Hacking the genome of fungi for smart foods of the future
Their feed and hay occupy land and use water that could be used more efficiently to directly feed humans.

My uncle was a cattle rancher in Arizona, on "marginal" land that didn't grow food for humans. It didn't grow enough for his cows either. We would leave out bales of alfalfa to keep the cows healthy. Alfalfa is grown in those big irrigated circles you've surely seen while flying.

Most beef consumed in the US comes from feedlots. Over 70% of "grass-fed" beef sold in the US is imported.

We just consume way too much beef

joshuahaglund··on Hacking the genome of fungi for smart foods of the future
If it's complicated you should probably explain. Your link doesn't disprove the parent -- it compares different water and land use of various cattle raising methods.

Over 60% of cropland in the US goes towards raising beef, a food which makes up a very low percent of the calories in an average person's diet.

joshuahaglund··on Study puts fermented foods, not fire, as pivotal moment in human brain growth
Iru, fermented locust beans, come from Africa. Tempeh comes from Indonesia. Seems like most fermented foods prefer somewhat warm temperatures
joshuahaglund··on Root cause of Alzheimer's may be fat buildup in brain cells, research suggests
I'm no biologist but it's my understanding that insulin causes cells take up glucose, not fats. And I don't see anyone suggesting insulin or the pancreas is involved in any of this. So what does the pancreas have to do with Alzheimers?

joshuahaglund··on Making steel without emitting CO2
Could they add H to CL then use the HCL and NAOH to drive a acid-base flow battery* during peak loads? I guess it'd be less efficient because the hydrogen would have to come from electrolysis.

joshuahaglund··on U.N. votes to end US embargo on Cuba; US and Israel oppose
Do you know much about shipping and logistics? It's all about finding efficiencies. If a ship visits Cuba, it can't visit any American port for 180 days. Considering how close they are and how much smaller a market Cuba is, I imagine shippers would charge more for freight to/from Cuba because now that ship can't be used for trade with the US. That ship is limited to/from places farther than Cuba (which are also smaller and poorer than the US).

If you're gonna complain about my data sources, can you tell me where you are getting yours?
joshuahaglund··on Automakers invented the crime of jaywalking (2015)
Nonsense. How much do you think bike parts cost? Basic pads for a bike are about $10-15, depending on rim or disc brakes. With most rim brakes you only an allen key. Most cars need a tool to depress the piston, not to mention you have to lift the car and remove, remove lugs, etc. Compared to a disc bike, you can compress the caliper using only a tire lever, and most bikes have quick release hubs or worst case 2 nuts to remove per wheel.

Looks fine to me. I think the unsafe thing is speed. Top speed of a cable car is 9.5mph. No vehicle appears to be going over 15mph. There's a cyclist pretty casually keeping pace with the cars. https://youtu.be/uINgSqEU26A?t=153

From https://aaafoundation.org/impact-speed-pedestrians-risk-seve...

"Results show that the average risk of severe injury for a pedestrian struck by a vehicle reaches 10% at an impact speed of 16 mph, 25% at 23 mph, 50% at 31 mph, 75% at 39 mph, and 90% at 46 mph. The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph, 25% at 32 mph, 50% at 42 mph, 75% at 50 mph, and 90% at 58 mph."

Slower speeds mean a collision is less likely to occur. We're pretty good at moving in crowded conditions without frequent collisions at low speeds. See also NYC sidewalks.

Also, it appears the video is slowed down. I played at 1.5 speed to make my estimates

joshuahaglund··on Automakers invented the crime of jaywalking (2015)
Maybe yours but not most people I know who use their bike frequently. Maintaining a bike is cheaper and easier than maintaining a car.

Aren't they both doing the economically incentivized thing tho? Are you saying maybe some things should be beyond economic incentives?
joshuahaglund··on SQLedge: Replicate Postgres to SQLite on the Edge
SQLite is much smaller and self-contained than postgres. It's written in ANSI-C and by including one file you have access to a database (which is stored in another single file). It's popular in embedded systems like, I imagine, edge devices
joshuahaglund··on If we want a shift to walking we need to prioritize dignity
That line had over 10k daily riders in 2019, before people stopped commuting to office jobs and it dropped to about 1500. https://metrolinktrains.com/globalassets/about/agency/facts-...

It's still less than half its previous average at 4700 daily riders now. https://metrolinktrains.com/globalassets/about/agency/facts-...

joshuahaglund··on What planes can you fly without a pilot’s license?
Part 103 aircraft must have a stall speed under 25 knots and a top powered speed of 55 knots in level flight. I don't fly but I imagine aircraft designed for lower speeds could be more survivable in a crash. Also you need less runway to land
joshuahaglund··on Suit alleges recreation.gov cluttered with junk fees, seeks millions in refunds
>You're forgetting the huge growth our National Parks have seen

Except this isn't true. 2022 saw 311.9 million visitors, up from 2000 which saw 285.8 million. That's not "huge" growth, that's not even keeping up with population growth (2020: 329 million vs 2000: 282 million). https://www.nps.gov/aboutus/visitation-numbers.htm

joshuahaglund··on Ignoring boys' emotional needs fuels public health risks
FTA: “The manning-up of boys begins in the cradle,” says Tronick. Fathers and mothers use far more emotionally rich language with toddler-aged daughters than sons, for instance. Fathers are also more likely to sing to and soothe their toddler daughters at night when they cry.

And "Praise them when they ask for help. Encourage them to share their struggles — with you, of course, but also with other trusted adults, a therapist or even friends."

And the article is full of links like this: https://www.irp.wisc.edu/resource/involved-fathers-play-an-i...

which suggests:

- Positive engagement: Involved fathers directly interact with their children in positive ways, including caregiving such as changing diapers and shared activities that involve play.

- Accessibility: Involved fathers are available to their children even when not directly interacting, such as cooking while the child plays nearby.

- Responsibility: Involved fathers take ultimate responsibility for their child’s welfare and care, including participating in decision-making regarding child-rearing and ensuring that children’s needs are met.
