  • Do we have a good idea as to why this has flattened out?

  • I believe by most metrics the ultra-rich are holding onto very little cash, most of it is invested (which means some company is spending it to hopefully make more). For example, most of Musk's fortune is in Tesla and SpaceX, which are employing people and selling things.

    I don't think shortage of cash for businesses (or even consumers really) explains the stalled labor market. Uncertainty about terriffs and fed rates are probably more indicative (and I think it's hard to argue that those are directly caused by wealth inequality).

  • "Spacecraft have more of an issue with overheating than freezing" is a really really ~cool~hot fact. Do you have an easy source, maybe somewhere that discusses techniques/history?

  • I think I understand the claim: the energy cost of keeping heat outside of a box should be proportional to the surface area, not how much stuff is in the box.

    This is true; but only once the contents of the box are already cold. I think what it neglects is that the stuff you are putting in is not already 0 K (or your fridge temp), it is usually much warmer. So the fridge must work rather hard to pump all the heat you add back out. (Incidentally, the fridge has an even harder job if the volume of the fridge container is bigger, since there are more places for the heat to hide/cluster.)

    We see the opposite with old fashioned fridges (an insulated box that you put ice into, and removed the water when it melted) or modern coolers. By making an insulated box, you make the interior become the average temperature of the stuff inside. To make the stuff inside cold, you must add something much colder to bring down that average, like a pack of ice. It's pretty hard to get 0K stuff on earth, so many things to bump into, hence very hard to use refrigeration to get things down to 0K.

    You might also be tempted by a selective insulator, that keeps hot stuff out but lets fast moving particles inside escape (so that the contents become cold). This is a classic thought experiment! Maxwell's demon. It turns out that any such intelligent barrier will itself need energy.

  • I am pretty sure the base state isn't 0K, it's whatever the average temperature around the object is. If you have a universe that is 10^4 K everywhere, then objects will tend to that temperature. Because the earth is actually quite hot compared to 0 K, your fridge very much is constantly using energy to keep the extremely hot outsides from warming the inside. It would get easier if the earth was colder.

  • If A.I. is so fast and efficient, and CEOs are paid so much, why not replace CEOs with A.I.?

    Jump

  • But CEO pay largely isn't in conflict with labor; it's in conflict with shareholders (namely, large scale investors). There are at least 3 fairly large groups of people who would all have to let the money run through their hands before labor sees a dime of current CEO pay. CEOs themselves (and, more broadly, C-suite), the shareholders (which you could subdivide by board-members vs hedge funds vs small investors), and governments (at various scales).

  • AI is currently really bad with business decisions. Like laughably so. There have been several small attempts, say letting an LLM manage a vending machine. I believe they've all flopped. Compare to performance in image creation/editing and programming performance (where, on measurables, they do relatively well). When an AI that could run a business OK exists, you should expect to see it happen.

    CEO's are paid so much primarily because the turn to paying them in stocks. This changed because of pay-caps for executives (so to compete for CEOS, companies offered stocks). The idea was that this would align their incentives with the shareholders. Unfortunately, this has lead to a lot of extremely short term company policy by CEOs, spiking stock value to cash out.

  • If A.I. is so fast and efficient, and CEOs are paid so much, why not replace CEOs with A.I.?

    Jump

  • This wasn't particularly true all that long ago. Huge buyouts and benefits for CEOs are both quite recent phenomena. Shareholders had a much better split not that long ago, and the social/family dynamics haven't had long to change so drastically.

  • I don't really buy this take. They have petty spats, noncompetitive practices, just like the rest of us. Seems like there are simpler explanations.

  • I don't think the two categories are disjoint; the doctors also do everything in category one.

  • It may be that you're tuning out sound, but there are alarms for the deaf. You might look into bed-shaking alarms? You put a puck on the bed and it vibrates the whole thing until you turn off the alarm (in an app or on the box elsewhere).

  • Free, ad-free, open source phone games

    Unciv: Civilization V clone that runs on a potato; a grand 4x strategy game. It seems pretty mechanically complete and has a lot of content. Easily modded. (Graphics may not be to everyone's taste)

    Simon Tatham's portable puzzle collection: Mathematically inspired Puzzle games with a lot of customization and reasonable interface. This includes classics like untangle (graph planarity) and solo (sudoku, but generalized). I personally really enjoy Tower, and hadn't seen it elsewhere (and like 15 more games besides).

    Chip defense: computer science themed tower defense. By the power of Turing, Noether, and Knuth you can strike down malicious packets attempting to corrupt your CPU. Good content, fun towers and educational bonus material, and I think it looks rather good. (Minor gripe/warning: early levels are optimally played with a lot of tapping that is not very ergonomic; this drops off after the first few levels.)

    Honorable mentions (not FOSS, but still free, MTX free, and no ads beyond fishing for a rating). Higgster's game compendium: collection of games in a consistent and pleasing artstyle. Includes things like solitaire, wordle, binaro, and mastermind (20+ games total, several more have been added in the last year). This is really very well done, give it a look!

    Flocks: Sliding puzzle game with excellent graphics and animations. Lots of levels, introduces new mechanics regularly, and easy to pickup or put down. I quite enjoy everything Robert has made, recommended!

  • Offhand: Do it in writing, or over short video seem excellent for many versions of this.

    Have a lawyer write it.

    If you are prone to dissociate, this might be a time to use that.

    Keep it short, avoid pauses and vague subjective wording.

    Schedule something you need to get to shortly after.

    Communicate at a large distance or from across a closed door. (Less good, rarely correct, use a blindfold.)

    Spend time practicing observing feelings and letting them pass without effecting you, try to notice when tears are coming early.

    Edit: how could I forget!?! Lithium. Needs a prescription and a few days though.

  • If a country needs to employ state-sponsored patriotism, it's usually because there's nothing to be proud of about the country.

    Jump

  • I agree that the first panel is off; I would replace it with "I'm going to work on my house because I want it to be the best house it can be", or something similar.

    And, at least for democracies (or similar), one of their bigger failure modes is that people:

    1. don't feel like they (do/can/should) contribute to the place they live;
    2. do not value the work that others do for the place and community;
    3. take for granted the natural resources, and don't safeguard them for the future.

    Consider how it is absurd for a normal person to run for public service, and how air quality has plummeted in so many places. I think it could be healthy to be proud of a group project you participated in. It's a bit sad that countries/states/cities/neighborhoods so often fail to be such projects.

    (Which I guess is all to say that we should gatekeep patriotic pride. That's a weird stance I've landed in.)

    horrible privacy stuff. The market really doesn't care; consumers will pay 3 less dollars for an insecure product. It's not even really their fault; it is extremely difficult to tell when software is actually secure. It is a pain to tell when some middle-man is actually selling your data or not, due to a carve-out in the TOS of a TOS of a TOS. Anyone upcharging for security could be scamming you, and with nontrivial probability is an NSA front.

    This all applies to companies, which can afford to pay for security experts and analysts. See this very old interview with Schneier. Generic consumer never had a prayer.
