It's focus stacking so basically just compensating for the way macro lenses and large apertures work. There's nothing artificial about it, the software is just layering the sharpest parts into the photo. It's a common technique, heavily used for things like astro photography and landscape photography as well. https://www.canon.co.uk/get-inspired/tips-and-techniques/foc...

Can you leverage focus stacking on a mobile camera? I poked around a bit for relevant apps but didn’t see anything credible.

My understanding is that modern mobile phone cameras do heaps of "stacking" across multiple axes focus, exposure, time etc to compose a photo that saves onto your phone. I believe its one of the reasons for the multiple cameras on most flagship phones, and then each of them might take many "photos" or runs of data from their sensors per "photo" you take. id love to see a good writeup of the process, but my gut says exactly what they do under the hood would be pretty "trade secret"ie.

Can any mobile cameras focus close enough to be useful for macro? Maybe you can buy a third party add-on lens?

Depends on what level of macro you want, but with modern phones you can get pretty close, usually with the wide angle lens.

I'd recommend playing around with it, it's a lot of fun!

Had a quick play with my iPhone 15. It doesn't give the sort of magnification you would need for insect close-ups. I will stick with my Nikon DSLR + 100mm macro lens!

Yeah it's far from being as good as a DLSR or mirrorless with a dedicated macro lens. Still, most people reading HN have one in their pocket and it can be a good test to see if you like the idea of macro. It does work with larger insects, on a pixel 10 pro my mantis fill most of the frame.

You can, depending on your definition of "useful". You can buy a cheap laser pointer, take out its lens, and put it over your camera lens. Tape it onto the lens for a temporary janky version or make a 3d-printed mount for something much better that you can easily take on/off.

I've personally found this little hack useful, but then again I don't have a DSLR and macro lens!

There's also digital ocean and hertzner cloud if you don't want to enter the AWS money pit. Though if you're looking to become a forensic accountant, AWS billing is great training

From the company that was the dominant web browser for a decade and left it to rot. They're pretty good at throwing away a lead position

Assuming bog standard lambda they'd have to rate limit a whole Aws region lambda range which would risk affecting legit usage. Bit of an arse way to behave against a service

Probably churned out using v0 which defaults to bloat

Pretty much how eventstoredb works. Deleting data fully only happens at scavenge which rewrites the data files.

I think it was a joke. It sounds like you read it as append-only, like most LSM tree databases (not rewriting files in the course of write operations), but I think GP meant it as write-only to the exclusion of reads, roughly equivalent to `echo $data > /dev/null`

I've forgotten how to count that low. [0]

That's nearly every ai start-up done for

For one thing, we'd make shit batteries.

IIRC the original idea was that the machines used our brain capacity as a distributed array but then they decided batteries was easier to understand while been sillier, just burn the carbon they are feeding us, it’s more efficient.

If I could write the matrix reverted, Neo would discover that the last people put themselves in the pods because the world was so fucked up, and the machines had been caretakers that were trying to protect them from themselves. That revision would make the first movie perfect.

Given that the first Matrix was a paradise that's pretty much canon if you ignore the duracell.

They farm you for attention, not electricity. Attention (engagement time) is how they quantify "quality" so that it can be gamed with an algorithm.

The Matrix only had people being batteries because a movie without humans in it isn't a fun movie to watch.

Sounds about right, most of us already are. But why would the AI need our shit? Surely it wants electricity?

People underestimate water needs. Enough to drink, wash, brush your teeth, flush a loo unless you're digging a pit at the bottom of the garden to go in

If you’re cut off from civilization, you can probably prioritize a bit and only use water for the essentials. Which means no washing/showering or flushing the toilet for a few days.

Showering is not an option without running water anyway.

It's more expensive to screw over large workforces in countries that actually look after employees rights Vs ones with weak protections. Have to love the endless "how can we fix this" from people looking to extract as much money as possible with as little regard for staff as possible.
