Plus they’re cheaper, relative to repair professionals’ labor.

If a new refrigerator costs the same as 100 hours of skilled labor, then a 10 hour repair job (plus parts that cost the same as 1/10 of a refrigerator) will be economically feasible.

But if a new fridge costs the same as 20 hours of skilled labor, and the more complex parts come in more expensive assemblies, then there’s gonna be more jobs don’t pass a cost benefit threshold. As a category, refrigerator repair becomes unfeasible, and then nobody gets skilled in that field.

Rick Astley has been doing this for years!

I think this is a picture before the most recent expansion. (They saw this picture and said “hmm not wide enough, too congested.”)

In the normal parts:

• 2 express/toll/HOV/carpool lanes
• 5 regular highway lanes
• 3 feeder lanes (in Texas, the highways tend to have “feeders” or “service roads” or “frontage roads” that run parallel to highways so that people can exit and enter, turn onto intersecting roads, and access local businesses, and Houston calls them “feeders”).

That’s 10 in each direction. But at any given time there might be merge lanes between the express and the regular lanes, between the highway and the feeder, or between the feeder and a turn lane. So at the widest point, around the major freeway intersection with another huge toll highway, they bump it up to one more of each type of lane, for 13 lanes in each direction.

There’s also a fair debate about whether the feeder lanes should count. After all, they have traffic lights and intersections to deal with. But on the other hand, driving on them is necessary to get on and off the highway lanes, so in a sense it’s part of the same highway.

Yeah, timestamps should always be stored in UTC, but actual planning of anything needs to be conscious of local time zones, including daylight savings. Coming up with a description of when a place is open in local time might be simple when described in local time but clunkier in UTC when accounting for daylight savings, local holidays, etc.

This meme format works best to absurdly overstate the uselessness of something you find mildly annoying. That’s when it’s funniest, because the criticisms are grounded in something real, and the low-stakes controversy makes the aggressive tone funny in context.

Self deprecation comes off wrong when it seems like the thing you’re criticizing is actually important, and that you actually believe it.

So it’s funny when the audience knows you don’t believe it’s important, either because everyone agrees it’s not important (“I can’t sing on tune to save my life”) or if it’s a particular example that doesn’t matter (“I’m such a bad mom because [something inconsequential]),” or if it’s a topic that people can see isn’t important to you (jokes about being socially awkward, bad at your job, etc.).

If you’re in one of those lanes, you can go pretty hard on yourself before it seems to go too far.

Wasteful of what, though?

If a particular farm can produce 1000 kg of meat and 500kg of bones/other waste in a year by raising female meat chickens, would it be a waste to devote that farm to raising 500 kg of meat and 400 kg of bones from male egg chickens? In a sense, that’s a waste of the farm to produce half as much meat as it can produce through killing chicks.

It’s a philosophical difference on what weight to assign to the lives of chicks, adult chickens, other resources including human labor, etc. The lazy shortcut is to maximize return on dollar investment with no regard for any of those moral, ethical, and philosophical considerations, and that’s what most of the industry does today, but even if you shift to a new moral framework you’ll need to decide how to weight those things.

Dual purpose breeds for both egg laying and meat production are poorly optimized at either. So the industry has moved onto specialized breeds that are best at doing one of them.

Plus raising roosters together is much more logistically challenging than raising hens. So they’d need much more space and much more oversight/labor. So rather than devote some resources to raising males of breeds that are good for laying eggs, they’d rather devote those same resources to raising much more meat from females of meat breeds.

Well yeah the key is to acquire that passive income before you’re born, through your parents, so that you can pursue your dreams as soon as you’re old enough to form them.

We have tons of evidence that it happened but our models for explaining and predicting it are bad at consistently and reliably explaining everything we’ve already seen, and each new discovery seems to break those models even more.

The theory is the model trying to explain how it works. The fact, though, is that we have evidence showing that it did happen, even if we don’t have a unified theory of how it happened.

Imagine a car crash site, where the cars have definitely crashed, but everyone has different debates about what caused the crash. Imagine further that the specifics of any person’s explanation has a few inconsistencies with what we see. So we’d have the fact that a car crash happened, but lousy theories explaining how it happened.

So anybody who says dark matter doesn’t exist is plain wrong, the discrepancies are there plain as day.

There’s dark matter, the real thing that exists and we can “see”.

No, we have observations that are consistent with the existence of matter that does interact gravitationally with regular matter, but does not appear to interact with light or electromagnetic forces. It’s not like any matter we know about, other than the fact that it seems to have gravity.

General relativity works really well to explain matter in the solar system. Bigger than that, you have to use something else. The general consensus is that dark matter exists, but it’s not strictly proven, as there are alternative theories.

Then, even bigger than that, dark matter alone isn’t enough, you need dark energy to explain some observations, if you assume that cosmological constants are constant. If it turns out that they’re not truly universally constant, we might need to modify some theories (including the proposed existence of dark matter and dark energy).

Then there’s the theory of gravity, this is our attempt to explain why gravity exists and why it does the things it does.

Not just the why, but also the what. We didn’t observe gravitational waves until 2015. People have proposed the existence of dark matter and dark energy because observed gravity doesn’t behave as our models would predict at certain cosmological scales.

Oh don’t worry, malicious .exe files were all over the forums back then.
