Watching people repair old electronics on Youtube has opened my eyes to the realities of real-world electrical engineering. In short: it's all about tolerances.

A power supply may have a nominal voltage of 5V, but anything from 4.8 to 5.2 is a-okay. Why? Because your TTL components downstream of that can tolerate that. Components that do 5V logic can define logic zero as anything between 0 and 0.8 volts, and logic one as low as 2 volts. That's important since the whole voltage rail can fluctuate a lot when devices use more power, or draw power simultaneously. While you can slap capacitors all over the place to smooth that out, there's still peaks and dips over time.

Meanwhile, some assembly lines have figured out how to aggressively cost-reduce goods by removing whole components from some circuits. Just watch some Big Clive videos. Here, the tendency is to lean heavily into those tolerances and just run parts hot, under/over powered, or just completely outside the published spec because the real-deal can take it (for a while). After all, everything is a resistor if you give it enough voltage, an inductor if the wire's long enough, a capacitor if the board layout is a mess, and a heatsink if it's touching the case.

As far as labors of love go, Stardew Valley is probably the most current example. People paid for this thing years ago, but Concerned Ape keeps adding new features anyway. The retro graphics give this thing a timeless quality out of the box, so it already looks "dated" - this hasn't stopped the robust player community around it. We'll probably see this game stay relevant for a long time.

IMO (not a scientist), moon dust is basically pulverized glass, only without the benefits of weathering and erosion. So think of lots of microscopic sharp, abrasive, shards of finely pulverized volcanic rock and obsidian. Get that stuff anywhere near a mucous membrane - eyes, nose, mouth, throat - and it's going to irritate you. At the same time, it's pretty much intert; well, at least the parts that don't instantly react to oxygen or humidity that is. My guess is that Schmidt is just a little more sensitive to the physical sensation of it, or perhaps he rubbed his eyes with a glove by accident, giving him an extra big dose.

And for the uninitiated, it's well documented that everyone in the lander was physically exposed to moon dust. There was no airlock on the lander, so every excursion resulted in bringing whatever was on the suits right into the cabin. They reported that it "smelled" like burned gunpowder, so they were at least all inhaling the stuff.

I used to really enjoy sites like this. I know there's joke accounts on Twitter and other sites here and there, but I haven't seen anything lately that has the whole site as one big running gag.

https://en.wikipedia.org/wiki/Q%26A_comedy_website

A Q&A website is a website where the site creators use the images of pop culture icons, historical figures, fictional characters, or even inanimate objects or abstract concepts to answer input from the site's visitors, usually in question/answer format. This format of website, most popular in the early 2000s, evolved from the much older Internet Oracle. The original progenitor of this type of site was the now-defunct Forum 2000. The Forum 2000 claimed to have run the site by means of artificial intelligence, and the personalities on the website were called SOMADs, or "State Of Mind Adjointness pairs". However, later Q&A sites usually dispensed with this pretense, with the most extreme example being Jerk Squad!, on which the administrators of the site provide many of the answers.

Out-crazying all the crazy passengers. This probably stops so many stupid rants and conversations dead in their tracks.

5/5 pro move.

FTA:

Two Democratic legislators are introducing a bill on Wednesday aimed at Mr. Musk and the so-called Buffalo Billion project, in which the state spent $959 million to build and equip a plant that Mr. Musk’s company leases for $1 a year to operate a solar panel and auto component factory.

The bill would require an audit of the state subsidy deal to “identify waste, fraud and abuse committed by private parties to the contract.” It would determine whether the company, Tesla, was meeting job creation targets, making promised investments, paying enough rent and honoring job training commitments.

If Tesla was found to be not in compliance, the state could claw back state benefits, impose penalties or terminate contracts.

There was so much to campus life that just felt natural and just ridiculously, offensively, convenient.

  • Practically everyone is roughly the same age as you, and that group is thousands strong (depends on where you go).
  • Just drop in on dorm rooms and say 'hi' to friends, whenever.
  • Dining is usually very close by.
  • Lots of entertainment options, most days of the week.
  • Included access to showers and fitness facilities (varies).
  • Free bus travel with student ID (varies).
  • Student ID discounts at some retail (varies).

The fact that we refuse to build communities outside of school with these features, just boggles the mind.


I'll add that this is practically impossible to replicate in adult life until you get into a "retirement community". And like college, those are ridiculously expensive too. If you're an undergrad and barely old enough to drink: I urge you to please live these days to the fullest. It's tragic but you really won't get another moment like this again.

Is there a reason people hate him? [...] isn’t he mostly known for giving away money and helping people out?

I may know why. The recently leaked PDF about how he runs his production company makes it patently clear: they aim to make successful YouTube videos, full stop.

Everything else is a side-effect. Not to suggest that they lack any ethics, but rather things like charity are there to get you to click and watch, nothing more. With enough exposure it's easy to get the impression that something is "off" with being click-bated like that. I'm not saying that behavior is deserving of hate, but it may help explain why people don't like his media.

Also, for people that are trying to make content in a much more honest fashion, Mr. Beast's popularity can be disheartening and frustrating. YouTube has clearly decided to reward this eyeball-grabbing behavior without any regards to the quality of the content. It's stuff made for the algorithm, rather than people showcasing their craft, skill, or interests. I'm guessing that people see their favorite makers and entertainers struggle to make a go of it by doing what they love, and see this guy come along and reap millions in revenue without any emotional connection to the output. To me, that's a recipe for anger.

Personally, I refuse to view popular click-bait stuff to begin with, and routinely filter such content out (click "not interested"). As a result, my YT recommendations never contain Mr. Beast content and I actually had to fire up a privacy window and click on this nonsense so I knew what the hell everyone was talking about.

Hey, look here buddy. You can't be your own comment thread and post all the plausible responses yourself like that. You're putting all the trolls out of work.

This is basically just as opaque as a charity or HOA, with different steps. Which is great unless your community is poor.

My contention with this concept is that with taxes, I can vote for people that manage both the money gathering rules and how it is spent. That and the money typically works in a much larger pool spread across a wide range of socioeconomic groups, which can vastly improve its reach and capability. On top of all that, it's also transparent. My guess is this has no such features.

Some of you may remember this absolute diamond of insanity that was the "4-Day Time Cube." This was the go-to example of the internet as a universal amplifier for communication - for both the sane and insane alilke. It was there from nearly the start of the world-wide web, back in the 1990's. Alas, it ceased to be some time ago, but it still lives on in our hearts.

For the uninitiated: welcome. Read and join the rest of us that are "educated stupid."

I'm calling it now. Even if his aim was to not destroy Twitter from the inside, he will absolutely say that was his goal when it eventually happens.

People like this never, pathologically, ever, ever admit making a mistake.

This didn't go down well.
