I've got a Moen Flo water sensor I really love. It was something like $25 with no monthly fee, has a surprisingly good app (also measures temp + humidity) and can even be paired with a valve that automatically turns off the water in the case of a detected leak.

What I like best about it is it can not only set off a siren and notify me in the app, it'll also send a text message and even call my phone which is huge because if I have a water leak I want to know no matter what.

It would be cool to see an equivalent map for freight rail.

These threads always focus on the lack of passenger rail service in the US but ignore that the US also has one of the largest, safest, and most efficient freight rail systems in the world[1]. I'd love to see it live!

This is really cool. Love that we're in a phase of AI tooling where you can just wire various projects together to create what (to anyone else who isn't following the space) looks like magic.

Also love that your kid was more impressed by the squiggly-lines visualization than the AI. There's a lesson in there somewhere I imagine re: dressing up magic to make people care.

Couldn't you just send a wire?

Right?! Everyone thought I was crazy to do this vs using something off the shelf but having total control over my notes app has been incredible.

I can tailor everything to my style of note taking vs dealing with the lowest common denominator feature set that tries to enable tons of use cases that I don’t need.

Just spitballing here but you could maybe do a 1-deep depth search… dot product on the initial search and also dot product on the highest confidence matched notes, then some filtering.

So if you have notes that associate the name to your dog, and you search for “my dog”, you’d still find those related notes?

Would require some experimentation but wouldn’t be surprised if that worked decently well out of the gate.

This is a great zero to one reference.

I built my own note taking ios app a little while back and adding embeddings to my existing fulltext search functionality was 1) surprisingly easy and 2) way more powerful than I initially expected.

I knew it would work for things like if I search for "dog" I'll also get notes that say "canine", but I didn't originally realize until I played around with it that if I search for something like "pets I might like" I'll get all kinds of notes I've taken regarding various animals with positive sentiment.

It was the first big aha moment for me.

At the time I found Supabase's PR for their DocsGPT really helpful for example code: https://github.com/supabase/supabase/pull/12056

If you don't need a certification on the results then cyclopure[1] is probably the best bet for reasonably priced testing.

I live in NYC and had the state do lead testing and cyclopure do PFAS testing. Was very happy to have both come back clean / zero detection.

Your comment reminded me that Cyrix had a "586" chip (technically was called the 5x86) and 12 year old me definitely thought it was an Intel when I bought it at a local computer show. Turned out to be a great little processor for the price.

Cyrix was a really fascinating company. Extremely short lived but had a huge impact on Intel's grip over the processor space (Intel lost all their lawsuits against them and nearly faced antitrust proceedings because of it).

It wasn't just you. At least around 2013 it was a whole thing dubbed "the San Francisco yes": https://thebolditalic.com/what-s-up-with-the-san-francisco-y...

Unlimited travel tickets like this open up so many opportunities.

I booked a Eurail ticket with my wife when we graduated college and still can't believe how amazing it was to travel at-will all around Europe for weeks on end. I think we paid $350 all in? They've gone up a little bit in price but they're still a steal.

We even sprang for the 1st class ticket, which turned out to be often empty and sometimes quite luxurious, since it was only something like $60 more.

Wait is this actually better? It's well presented in the ad but:

- that removable veggie holder in the door looks crazy heavy and super awkward to put back in place (lining up at a sharp angle while gripping likely slick sides)

- you have to open the refrigerator door to get at the freezer

- the door compartments are narrow and probably can't handle odd sized containers

- the shelves have holes in them so anything that drips off that uncovered plate of food gets all over everything below it

- the ice ejector is completely unnecessary in our current world of ice makers. I doubt that fridge has a water line coming into it

- the shelves don't look like they have adjustable height so you're stuck with 3 shelves that can't fit a gallon of milk

> At the heart of ETIAS is an electronic database system to better track who's coming and going.

Lots of people online annoyed at having to pay a fee (7 euro) to travel but this is what it's actually about.

Curious to know if EU governments are limited in what they can currently do with passport entry/exit data and if this expansion allows them to do more?

Isn't this it? https://huggingface.co/stabilityai/stable-diffusion-xl-base-...

The 90s were wild. We used to just print entire credit card numbers on the receipt!

You can also marry these techniques with pgvector to find related content through embeddings. I've found this to be pretty magical.

I'm no expert on this and my interest has purely been from doing a home filter setup in an NYC apartment and trying to figure out what the best practices are, but my understanding is plants can also be impacted through uptake but there isn't too much evidence it's resulting in higher levels outside of known PFAS hotspots.

The FDA suggests that the primary issue at least in the US right now is seafood[1].

Last year the EPA massively tightened its recommendation for PFAS in drinking water from 70ppt to 0.004ppt for PFOA and 0.02 ppt for PFOS[1]. I don't think anyone is enforcing anywhere near that level yet... CA is the strictest in the US at 5.1ppt.

The scariest part of this to me is that even if you do manage to get it out of your water at home through filters or reverse osmosis it's probably in all your food at high concentrations. At least as of 2019 in Canada and the EU PFAS levels in retail meat are at 500-700ppt and the US is entirely unknown [2].

It's also pretty tough to even figure out what filter setup to use at home since the NSF filter standards are still for the outdated 70ppt metric. Duke did a decent study on actual filters a few years back[3].

It's true. Exiting FB's incredible in-house information & developer tools culture is for many people one of the hardest things about leaving. Ex-fb groups maintain lists of potential "in the wild" replacements for each tool but very few are up to the task (pun intended).

Cloud storage is a massive ripoff. Just go buy a 2TB drive at Best Buy for $120 and stick it in an external usb-c enclosure from amazon for $15.

> Does someone watch an entire 2+ hour movie with a sweaty headset strapped to them (and plugged into a socket) instead of on a couch with their family/friends?

I actually tried watching a downloaded Netflix movie on my quest while on a cross country flight once and it was surprisingly not terrible.

Also I managed to get away with not ending up on some viral twitter post despite probably looking ridiculous.

That said if it wasn’t so bulky I’d probably bring it on more flights but it’s such a pain to lug around I haven’t really done it since.

Yes it's this. This has nothing to do with 3rd party app operation and everything to do with generally closing the gate to the data garden.

The value of reddit's content to non-reddit entities is rapidly increasing as its monetizable use shifts from a set of signals on which to build first-party ad targeting (which they never really figured out) to generally useful llm training data.

Early in the pandemic there was a very aggressive "you don't need masks and please don't buy them because hospitals need them"

Ex: "US Surgeon General Dr. Jerome Adams not only wants people to stop buying facemasks to prevent the novel coronavirus, but warns that you actually might increase your risk of infection if facemasks are not worn properly. [...] On Sunday, Adams posted on Twitter that people should stop buying masks. Rather, he tweeted that to keep yourself and those around you healthy, wash your hands often, avoid touching your eyes, nose and mouth with unwashed hands and disinfect surfaces."

I remain flabbergasted that Brexit happened but wasn't the overwhelming victory of Boris Johnson & the conservative party at the end of 2019 basically a re-statement by the population that they wanted it?

IIRC that was basically a single issue election after which Brexit was more or less fast-tracked without continued internal opposition.

Up until that point there had been a series of delays and rejections of Brexit plans in parliament and it looked like it might not happen.

(I'm not British and have only watched this from afar so I'm actually curious about if this read is accurate.)

In theory every store that sells rechargeable batteries in NYC is also supposed to accept them for disposal.

I've found that occasionally true... but as you say for things like laptops without removable batteries it feels a little weird to just leave them in the piles by the door that many of these stores have.

It does seem perfectly in line with the 1% rule[1] for social networks. In this case I'm not sure if a user is a content creator or not so it's a little unclear if this is 1% of 1% or 1% of all.

We've been living in the (golden age?) of crowdsourced information for a while now.

AI-generated content at scale (especially if it has marketing dollars behind it trying to influence future models) may well cause a resurgence of curated / authenticated information services.

I’d frankly be happy with more apps just being offline tolerant.

Surely google maps knows I live in NYC by now but if I’m between stations on the subway the odds of me being able to pan around at various zoom levels is surprisingly low. Surely basic semi-static highway and geographic information could be locally stored (this basic information used to fit in a spiral bound book we’d keep in the back seats of our cars).

iMessage just gives up if a message can’t go out rather than queuing it.

Heck most weather apps won’t even show me the previously downloaded forecast if there’s no network, they just show “-“ or a sad cloud image.
