You discounted space dust.

No I didn’t — it would thermalize and radiate.

This is not my paradox, and it’s not really a paradox at all, as the big bang model explains it nicely. There are many nice articles on the topic of you’d like to read more about it.

Yes. But why is there an absence of light?

If there are infinite stars, then every direction you look would encounter a star. (Things stay the same brightness per subtended angle as they get far away. Space dust doesn’t matter, as it would thermalize and radiate.)

So, the universe can’t have infinite luminous matter, be static and ageless, because if it were then the night sky would look like the surface of a sun.

This may all seem obvious, but it’s neat that you can figure that out with the naked eye.

Olbers’s paradox, also known as the dark night paradox or Olbers and Cheseaux’s paradox, is an argument in astrophysics and physical cosmology that says the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe.

The night sky being dark has some profound cosmological implications.

Widely regarded as the best Seinfeld episode is The Contest. It’s about who can go the longest without masturbating, but what makes it great is that they never say that explicitly — it’s just euphemisms and insinuation. And it’s hilarious IMHO.

I believe they initially wanted to spell it out, but the networks wouldn’t let them (I could be wrong). Definitely for the better that they danced around the topic the way they did.

(Yes I know, Jerry Seinfeld is a problematic person, I’m just trying to answer the question…)

I just wish we’d have neither inflation nor deflation.

Some tech has followed this pattern. For example: entry level Mac laptop in ~2000 was the iBook, priced at $1599 ($3k+ in today’s dollars). The current entry level Mac laptop (M4 Air) starts at $999 — cheaper in absolute dollars, and way cheaper in relative dollars.

(Macs are just an example since Apple doesn’t have a very extensive product list, so there’s only one “entry level” laptop to choose from. And yes it’s fair to ask if the relative specs have just gotten worse, but I think this is also the opposite — the iBook was iirc criticized as being underpowered, whereas the M4 Air is afaik well regarded.)

Compensation for engineers in the Bay area will average much higher than $200k, and that’s not counting benefits (medical, etc.). So cost to the company will be way higher than 200k/employee.

For a project that has hardware, there will be large expenses associated with that — custom silicon has huge setup costs, for example.

You mentioned ham radio — definitely fun! It’s a process to get into it though, as you need to study/pass an exam, and then you need a radio. Radios range from cheap ($25 or so) in the VHF/UHF (“walkie talkie”-style) to more expensive for an HF rig ($1000 range for 100W HF). If you want to get into low power (“QRP”) it can be much cheaper. You also need a fair amount of space for a good antenna setup…

There are tons of different communication modes, some without a computer and, like you mentioned, some that use computers. wsjtx and fldigi are popular programs.

Good luck!

That’s because you’re thinking of trucks used first and foremost for heavy duty “truck stuff.” That is not the only market for trucks, at least in the US: https://www.thedrive.com/news/26907/you-dont-need-a-full-size-pickup-truck-you-need-a-cowboy-costume

According to Edwards’ data, 75 percent of truck owners use their truck for towing one time a year or less (meaning, never). Nearly 70 percent of truck owners go off-road one time a year or less. And a full 35 percent of truck owners use their truck for hauling—putting something in the bed, its ostensible raison d’être—once a year or less.

Here’s January of this year. San Francisco, so pretty moderate weather — typically don’t run heat during the day, and low 60s at night (if at all) during the winter. Large temperature gradient throughout house, typically.

South facing windows gives kitchen and living room a greenhouse effect, particularly in the winter, hence the large daily temperature swings:

We’re expecting a baby. Do people travel with a baby? Is it safe? Is it insane? I think we’re just gonna have to stay put for 3 years or so.

If your baby isn’t super fussy, the transportation difficulty (in our experience) is more in the logistics getting to/from airport, and dealing with other ground transportation. We just flew 5+hrs (coast to coast, US) with a 2mo and a ~3yo, and it was a piece of cake (typing that, I’ve jinxed the return flight…).

We haven’t done international travel with our kids yet, but we will eventually. When I was 2 my family went to Europe — some countries were meh with respect to kids, but Italy (from my folks’ retelling) was fantastic, as there is (or was) a big cultural love for young kids.

YMMV of course, but it’s absolutely doable! Kids — even starting as babies — have personalities, and you’ll get a sense of what’s appropriate with yours. Good luck!

Good point — it is “incrementally free,” although I guess if you count tire wear and tear that’s not even true.

Your local city college may or may not offer free classes (in San Francisco, you just need to show proof that you live in the city with some legal status).

Some public transportation is free for certain groups (youth and folks experiencing homelessness can get free passes here).

“First X of the month” at the zoo/a museum/whatever — lots of venues have free events.

A jog, bike ride, hike — lots of great stuff outside!

The bank doesn’t own the house, they just have a significant lien against it. Maybe a potato potato situation (how are you supposed to spell that phrase 🤔), but it is an important distinction.

Landlords can get pissed if you paint the walls/change appliances/remodel/etc., but so long as the property is properly insured (and you make your loan payments on time) the bank probably isn’t going to bother you.

Landlords can — and do — place restrictions on quiet hours, guest policy, who is allowed to live there, etc. Owning is definitely different.

We still use leaded gas for aviation, as does (I believe) the EU (I’m guessing RoW, too).

(Supposed to be banned this year in the EU but AFAICT pushed back until 2032.)

A French court has ordered Google, Cloudflare, and Cisco to poison their DNS resolvers…
