Officially you can’t be fired for striking right? Guessing there’s a lot of ways a company can get around that though.


Under the Wagner Act you can't be fired for concerted collective action in the workplace, if the goal of such action is to improve working conditions. That is a much broader protection than for just strikes (which are pretty narrowly defined).

But like you say, any corporation worth its salt can find ways to get rid of problem employees without violating the letter of the law even when it's not already planning big layoffs.


If you strike against the US government as a public servant, yes you can be fired for breaking the law.[1]

Strictly within the context of the private world however, I don't know.

Modern equivalent of selling shovels during a gold rush


yes, 12 months ago jina was an open source semantic search tool, than a whole bunch of things, now a prompt optimizer and bunch of ai tools


+1 to this, I feel like they are in the middle of an existential crisis. They keep shipping out product after product each month now. I think that they are struggling quite a bit to meet investors' growth expectations.


Kind of weird that you are calling out drywall here, what other building material makes sense for interior walls? And when you say no insulation do you mean in the interior for sound proofing? Exterior walls certainly have and require adequate insulation to be to code.


I'm reasonably certain it's an exaggeration on the authors part.


I tried baking cookies based on a chatGPT recipe… everything looked right glancing at the response so I dove in and started making them. About 2/3rds the way through it became obvious the steps were correct-looking gibberish.


No shit. Why are you surprised by this? There is no right way to make cookies. This isn't what GPT does.



This entire thing ends up being a Tesla marketing scheme


It’s not like you can just crack it open and the expensive metal falls out though. It’s an industrial process.


Ummm, no that’s almost exactly how it works actually.

Sort of. The bulk of that material you see is just a ceramic substrate. There's only a few grams of valuable metals in each converter.


Plus with literally hundreds of millions of dollars in profits there’s no problem doing some “industrial process“


It isn't hard to melt those metals out. I used melt aluminum in my backyard, and the forums for that had discussions on other metals. While a backyard process is not going to recover all the metal, it is still going to get plenty.


Can you provide a link with this info? I’m only a casual follower of this stuff but it seems hard for me to believe


The basic principle is that space itself is expanding—the empty stuff between all those stars, planets, and galaxies. Not only that, but the expansion of space itself? It’s accelerating. And the further away something is, the faster it’s accelerating. Allow this play out over time and with acceleration unbounded, space itself starts to expand faster than the speed of light. And since the speed of light is our universal speed limit… that means the far reaches of universe will forever be out of reach. Eventually our own night sky will go dark (minus the stuff closest to us like the sun, Milky Way, and Andromeda) as more and more objects continue their acceleration away from us.

One consequence of which is that if intelligent life arises in the Milky Way again after that point, they will likely have no way of knowing that there ever were other galaxies beyond the local group.

We're somewhat lucky to be around to see the universe when it's comparatively young.


Can't that be true for us, though? If we had JWT 4 billion years ago, who knows what we would have seen.



He’s referring to the cosmic event horizon

“ In an expanding universe, the speed of expansion reaches — and even exceeds — the speed of light, preventing signals from traveling to some regions. A cosmic event horizon is a real event horizon because it affects all kinds of signals, including gravitational waves, which travel at the speed of light.”

https://en.m.wikipedia.org/wiki/Event_horizon


I was just going to ask about gravity. TIL that gravity travels at the speed of light. Thanks!


Or light travels at the speed of gravity but for a different order of discovery and convention.

Massless particles all travel at the speed at which causality can propagate through the universe (though they themselves do not experience speed because they do not experience time). The fact we reference it as the speed of light is just scientific idiom



Imagine you’re swimming in a magical pool with some friends and the entire pool doubles in size over the course of a second.

Your friend right next to you who was one foot away is now two feet. The absolute distance just grew by 1 foot, a rate of 1 foot/second.

Your friend across the pool who was 10 feet is now 20 feet away. Absolute distance just grew by 10 feet, or a rate of 10 ft/sec.


You probably mean the pool quadruples in size, meaning it doubles in length.


No, I mean doubles across all axes. 1 unit cubed becomes 2 units cubed.


It's like a balloon. Take two distances when balloon is empty. Let's say furthest points of each other (10cm) and halfway points (5cm) When you inflate the balloon the distance of furthest points increased to 20cm. But the 5cm is 8cm and not 10cm. The same in space. the further you go the faster it expands. The event horizon is the point where the expansion is faster than the speed of light. Any photon emitted will never reach us. The crazy thing is that according to some theories even the space between atoms will be beyond the event horizon.


Here's a link about this idea by Ethan Siegel, and its HN discussion thread (thanks 'petilon for helping me remember the author):

Is there any IP created because you generated a particular program / interface? Perhaps not the code itself but the end product? In the early stages of my career we were advised to never test out a competitors product for fears that we would inadventently copy something of theirs that was protected, but at my current company we compare our product to our competitors regularly. No risk there?


My question is similar -- what ideas are there to patent in a communications app? Isn't it just user profiles and messages?


We have this problem too. When we send a request to create an entity in an external system, before we get the response back with the entity Id, we already have received a webhook saying said entity was created. Makes a basically trivial workflow quite confusing.


Anecdote... in colorado the snowpack level for 2021 is average-ish. And we just got a boatload of rain, its the wettest spring in a while.


The statewide average is deceptive here. The northern Front Range (South Platte basin) had a very snowy / wet spring, but the rest of the state is well below historical averages.


Unfortunately the part of Colorado that feeds much of the rest of the southwestern part of the US it's water is still below average in snowpack this year:
