on: iPhone 16 cameras vs. traditional digital cameras
Focal length wouldn't even be an issue if the photographer was taking the photos from the same position. The fish-eye effect is literally because the photographer is closer. Cropping a photo with a different focal length will give the same composition and difference will be the distortion introduced by the camera and the image processing.

Neat. I usually just use 7zip to open .exe and .msi files.

A game such as Turing Complete will give the same sort of understanding of the fundamentals of computing, although not a physical learning experience.

on: Dune ornithopters flap their blades in the wrong plane for vertical takeoff
Assuming that they're capable of changing the wing angle of attack, they seem to be doing the same motions that dragonfly wings make during flight, including take-off. Here is a slow motion video of one taking off (note the vertical motion of the wings):

You'd be better off with an engine specifically designed to be efficient. Turbines are great at many things, but they are complex and don't scale down very well. They were primarily used where high torque and power is required, and they just aren't practical outside of that.
A better option would be a constant speed ICE engine running at it's peak efficiency (like a diesel-electric train).

on: Why do bees die when they sting you?
This article makes one assumption without justification and then follows it to a wrong conclusion.
When bees sting other insects they can sting them multiple times, like a wasp. If you give them time a bee will usually be able to work it's stinger out of you and go on it's merry way. Their stingers just happen to get stuck in skin.
Here's a basic video discussing the topic: https://youtu.be/nTVsqc2CCGo

on: The record-breaking -108.00 diopter myopia lenses (2016)
The article says that they're biconcave, which means that the thinnest part of the lens is in the centre (similar to a red blood cell). For high-myopia lenses, they often remove the lens material away from the centre to limit the maximum thickness at the expense of reducing the field of view. The resulting surface is usually left unpolished, but the lens underneath will still bend light, resulting in the circular patterns you mentioned. In this case a very large amount of material is removed as they would be impossible to use with a conventional frame otherwise. The alternative would be to use glasses with very small lenses.

Inline whitespace summation at the same time as mathematical operations seems like a problem. I don't think that there's a standard order of operation for that sort of thing.

Would it still be a bicycle if the pedals aren't connected to the drive? This configuration would make it more like a scooter with a pedal generator.

on: LastPass users warned their master passwords are compromised
If you want to store you passwords locally, then at least use something like Keepass or KeepassXC. It's far from a perfect solution as it's still vulnerable to targeted attacks when it's being used if your computer is compromised. But at least they're not store in plain text. Also password auto-typing and generation are nice to have.
You can sync the encrypted files to your phone or other computers.

I just wish that they'd add a text or symbol in the top of the global and local dynamic filtering boxes. Every single time that I use it I have to look up which one's which, because it isn't obvious and I can't remember.

on: Jpeg2png: Silky smooth JPEG decoding – no more artifacts (2016)
That reminds me of a quote about chlorine trifluoride:
"...It can be kept in some of the ordinary structural metals—steel, copper, aluminum, etc.—because of the formation of a thin film of insoluble metal fluoride that protects the bulk of the metal ... If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes."

on: Hey Dropbox, why can't I compare file versions like this?
Modern MS documents files are zipped XML. To do this comparison they would need to unzip each file, run it through a rendering engine and hold it in memory, and then do version comparison. For this to be feasible you would need to use a file format that supports this sort of comparison in a way that isn't very resource intensive.
