Is there a lower density limit for having a magnetosphere though? A habitable planet with 1.5x earth radius and the same mass would be much easier to get off of.

I’ve been wondering what a hypothetical perfect habitable planet for spacefaring would look like. Could you have one where a plane line the SR-71 Blackbird or an even less capable aircraft could simply “fly” into orbit? Or what about something Earth-like but with a flat plateau at 15,000 m where you could launch rockets from?

I am not voting for anyone in the 2028 primary who does not agree that the US should comply with International Criminal Court arrest warrants. If the subject is no longer in government, they need to be dragged onto a plane and sent to stand trial.

The graphs in the paper show the temperature 1 km away from the data center being 8°C higher and attribute that to heat emitted by the data center. That should start the alarm bells that something isn’t right with this paper.

Here’s a post going into the problems with it;

Natural gas is used to produce hydrogen, which is then used in the Haber-Bosch process to produce ammonia from nitrogen in the atmosphere. Only about 6% of natural gas is used to produce hydrogen, so even if the price were to rise substantially, we could divert natural gas from other uses and have plenty for making ammonia. We also have other ways of producing hydrogen, it’s just that natural gas is more established.

PEM electrolyzers paired with cheap solar in countries with high insolation can now produce hydrogen for less than the cost of natural gas, but we’re only recently starting to see the construction of the large-scale green ammonia plants needed to accomplish this. Egypt is currently constructing a 100-MW green ammonia plant powered by solar energy. Even if you didn’t have enough PEM eletrolyzers you could still just pass current through some salt water and produce hydrogen, albeit much less efficiently.

It’s not going to be a catastrophic issue.

Is there more detail on the process beyond what’s in the blog post? I could see a scenario in which the training data was just generated by running multiple playthroughs on a $500,000 GPU at impossible quality, creating a copy of what that would look like on a mid-range GPU, and then training a model. I’m not sure I would object to that.

I had all kinds of feeders. They were great and I loved looking at the wildlife, but they dropped a lot of seeds on the ground around the feeder. That attracted mice and the mice decided they should build homes near their food source. They decided the best place to live was inside of my cars.

They ate through the wires going to the brake lights, left seeds everywhere, got into one seat and ate the occupant detection sensor, ate 3 seat belts. I managed to fix the seat belts for ~$300 and the brake lights I spliced back together. Sensor is still shot and I’m not sure I even want to mess with disassembling the seat.

The empty space between the components in the frunkless version makes it look like they would be a lot easier to access for DIY repair. Certainly easier access to the 12 V battery would be an improvement.

I got an Asian pear tree, a Nijisseiki specifically, a few years ago. Asian pears are usually really good, particularly the expensive ones that come in little pear bear bras. When you have your own tree though, you can harvest at absolute peak ripeness without having to worry about them going bad. Absolutely amazing fruit. Chill it in the refrigerator for an hour or two before eating so it’s cool but not cold. Perfect dessert.

I started using leather conditioner on my work gloves and it probably doubles the lifespan if you use it regularly. Especially if they get wet or contact soil, that really pulls the oils out.

I’ve been thinking about employee stock options lately. The original idea was that options would vest as a result of executives increasing the stock price through good business practices. Now though, so much of the market is occupied by index funds that major companies’ stock prices will rise just for treading water as everyone keeps pumping money into retirement accounts comprised largely of index funds. So instead of a reward, they just become a way to skirt income taxes as long as you hold the stock long enough. The article mentions buybacks as well, which can also inflate the stock price guaranteeing options vest.

half the year it feels like my feet have been stabbed because they get so cold (slippers are not enough)

Get some down booties. It’s like your feet are cocooned in a loving embrace of warmth and comfort.

I could use an 8k 42” OLED monitor for work. I’d need a 130” TV for 8k to be noticeable given the distance I sit from the TV.

There’s not really any data other than a rough distance from its star. The atmosphere could be thick enough and with the right combination of greenhouse gases that the temperature at the equator is 23°C year round. We do know that it’s only receiving ~30% of the energy from its star as earth does from the sun, which is what they’re basing the low temperature estimates on.
