Water occurs in nature without human intervention. I don't think the same can be said for PFAS.

For a big chunk of the industrial age we've operated on the assumption that the global environment is big enough and capable enough to just eat or neutralize just about anything we dump into it. I think there is utility in defining a category of human-produced things that we have been able to determine the global environment can't eat or neutralize, and also that cause harm when people are exposed to them.

You could give this category a lot of potential names, but "forever chemicals" conveys the idea pretty effectively IMO.

Giving them an address for pickup works as well as a location based tracking and allows you to tell them to meet you 5 blocks away if you are on the move when you call.

The driver didn't know the neighbourhood nickname you gave..did you give them an address? You have to searching the map on Uber anyways, did you search your google map for the address?

Taxis will go down the streets you tell them while you drive. Turn left or right next lights work. It's more flexible than ubers pre determined route.

Immigrants have more street smarts than you give them credit for. They literally uprooted their lives from places who generally scam more than the places they move to. They have taken a scammier cab ride before they even left their home country.

But Uber does scam you as a matter of course, they've just hidden it in such a way that you're willing to accept it because it's a slight inconvenience that extracts extra money from you, rather than making you go out of your way to do something.

I'm not an expert too but AFAIK ferrofluids are actually attracted by magnets. The spikes are probably as a result of having strong and weak locations of magnetic field and the the liquid rushing into those.

But yes, Maybe I'm interpreting the video wrongly. Yet, to me it looks like the bulky part of the sample is being repelled by both poles of the magnet as it stands upright with the pointy end at the bottom each time. IMHO if this was due to attraction, the pointy end would be at the top.

Long chain like PTFE is fine. The issue is short chain fluorosurfactants (think PFOA and GenX) which contaminate the environment around the factories that make PTFE, harm the workers in those factories, and probably end up in trace amounts in the final products as well. These are very chemically stable in that they don't react well with most things, making them long lasting in the environment, but they do interact (but not react) with animal endocrine systems, which makes them so dangerous.

> A crashing application has a bug that needs fixed.

Sure, but you can fix that bug after it's been auto-restarted. Assuming this is a service that, say, customers rely on, your customers don't care about the details. They just care that they're able to use your service and get their work done.

Not having some sort of auto-restart or auto-healing system only serves to prolong downtime. Obviously you need to be alerted of these restarts so you can find the bug and fix it, but overall I'd value uptime over the fairly low probability that allowing it to auto-restart might expose some sort of security issue.

Of course there may be some circumstances where reliability is by far the biggest concern, so allowing something to crash and stay down may be preferable. I just think that's going to be a small minority of situations, for most people.
Which should honestly be a warning sign.
This reminded me of the Sirens of Titan. The main character makes some bad investment decisions, including in hovering furniture that wobbles uncontrollably when touched.

Well for one there have been gov efforts before under Obama but it didn’t result in a big shift (for whatever reason). But also I think it’s very elitist and with a lot of hubris to suggest an entire population should easily be able to shift from one thing they’ve done for decades with all of the structural support in a community of it, to something else. Most people are not so fluid, both in capability but also receptive to change. Throughout history change gets resisted.
I think this is a large part of it. For me certainly I realized during the pandemic that I was starting to feel really isolated and needed to make a conscious effort on my social life, but I also think this was a net win. True friendships are formed and strengthened by putting in effort. Ephemeral office connections are fleeting. I think if your social life dies when working remote it's a sign of a problem the office was papering over.

I also believe there are those for whom this is not enough and they really do need more time around people than can be obtained outside of work, but there are solutions for these people as well (ex co-working spaces)

Things might changed but last time I checked you could easily call C function but you had to kind of export each single C function, structs etc. You couldn't just import single header file and be ready to call any function in the library.

> It's just that if you read papers most people publishing aren't using giant clusters.

There is a massive difference between what is necessary to prove a scientific thesis and what is necessary to run a profitable business. And what do you mean "giant clusters" in this context. What is the average size of the clusters used in ground breaking papers and what is their cost? Is that cost a reasonable amount for a boot-strapped startup to experiment with or are we getting into the territory where only VC backed ventures can even experiment?

> There's a whole field of people who are finding ways to shrink models down

Of course the cost of running models is going to come down. The literal article we are responding to is a major part of that equation. You seem to be making arguments about how the future will be as support for an argument against how the present is.

Presently, hardware costs are insanely high and not coming down soon (as per the article). Presently, useful models for a large set of potential applications require significant cluster sizes. That makes it presently difficult for many engineers to jump in and play around.

My opinion is that the cost has to come down to the point that hobbiest engineers can play with the high-quality LLMs at the model sizes that are most useful. That doesn't imply that there are no model sizes for other use-cases that can't be developed today. It doesn't imply that the price of the hardware and size of the models will not fall. It just implies that dreaming of a business based around a capable LLM means your realistic present day costs are in the 10's of thousands at a minimum.

Superconductor are more efficient at transmitting energy, here are some consequences:

- Cheaper electricity transportation

- New kind of batteries

- Consumer devices that don't heat up as you use them

- Simplifies the design of fusion reactors, which means we could have fusion sooner and cheaper

- Probably lots of things we can't even think of

If this is true, then you still have a lot of time before you can do industrial replication but given the stakes I imagine we will see immense inflows of capital into this.

Car sharing is great. Sometimes you need to go somewhere for a couple hours and hiring a driver becomes very expensive. Or you need to transport something.

How well does your integration handle stacked PRs (if at all)? I find that the majority of my interaction with git is super basic that I get no value add replacing `git add -p` (esp. since I'm always in my terminal with Vim/tmux).

What _is_ annoying and something I could probably automate if I thought about it for more than a few minutes is when:

a) I have stacked PRs for isolation/workflow purposes in the form of: A <- B <- C

b) we use squash and merge

c) now when A gets merged I need to fix B and C because while the change set is the same the history is not (because of the squash & merge)

d) when B gets merged I have to fix C for the same reasons
> those who want to remember where/how to find things, and hate relying on fuzzy search to surface them.

I'm in this camp, but with a bit of nuance. Fuzzy search tends not to work well for me -- if I can't remember the exact name of the application I want to use (and I often can't), then search is an iffy way to locate it.

But mostly, it's about not liking to switch between using the mouse and using the keyboard. If I'm firing up a program, I'm almost certainly using the mouse at the moment. Switching to keyboard adds a bit of unnecessary disruption.

the dft results are definitely interesting, but i note that with the caveat that my background is in experimental condensed matter physics for materials like this and not theoretical, my understanding is that the dominant feature of the conclusions (the flat bands) is a necessary but not sufficient condition for superconductivity in the way the authors describe.

again, in experimental condensed matter physics it's acceptable to do a fine experiment and then throw in a half-baked "theoretical underpinning" to appease reviewers, so I wouldn't be surprised if the superconductivity turns out to be totally unrelated to the mechanism proposed in the paper. i would really like to see some more robust characterization work(biased because this is my background), hopefully some of the labs doing the replication studies can take a look at the juicy stuff
