I’m sure you’re right, in absolute terms. Still, a SAR helicopter with jet turbines and a multi person crew is much more visible than a battery powered electric drone carrying one man alone.

Can not see the drone and shoot it down using thermal camera or ir seeking missile

Not for me. So there’s that. But tapping anywhere on screen does start the sound.

I was under the impression that many providers let you define a response schema. So - I believe - you can say «json list containing these options» and it will work, just be more expensive. Not sure about accuracy.

Which JIT languages use much simd in generated code, in general?

Exactly this. The process is super complex and expensive. The result, a cpu, is sold for a few dollars. To be profitable, the scale / volume has to be absolutely massive!

It spends some battery, but my electric car heats much faster than my diesel cars ever did. Why on earth would I use a diesel heater that’s more expensive to run and slower?

Reminds me of the time when visual studio would show one value of a variable, but print would show a different one. Never trusted VS again after that.

Then how do you log in? Not all sites let you keep password logins after.

Just like breaking crypto in the age of cloud is more about cost than time, this will lead to legal attacks based on the same principle. The biggest wallet wins.

They’re not stable except at L4 and L5, and they all assume oke body to be massless. Arguably they are 2-body orbits for that reason. Not sure but suspect that this atlas contains non-massless bodies.

I have my skills in my dotfiles repo, then symlink them to my home directory and/or projects where I want to use them. Project specific ones go into the project.

I make skills for «this is how I like to do things in this company / project». Query test database, git branch names, commit message style, which cloud things can be inspected like logs etc. I don’t see the point in trying to teach the models things that is in the documentation of git, python, what have you. They already know.

Cool idea! I think it would look better as a function than an alias, but that doesn’t matter much.

I’d be curious to use them on larger data sets. Log files, for instance. High volume, might be low value per line but not much cost per token if you already have a gpu to interpret them using a LLM.

Apple airtags last maybe a year on a CR2032, from experience.

Energy loss from air resistance typically is quadratic, not exponential, with regard to velocity. So it’s worth much less than you’re arguing. And the arm has to rotate from what I can understand, so the end rotational velocity - and hence, rotational energy - would be the same?

This is so nuts. It’s literally a multi device mouse - supports 3 bluetooth connections in memory, but I need to install the options app on every single pc/mac I want to use it on. Nuts!

I did the same. I’ve been happy with the solution, except that many years later, I still get emails to my gmail - I just keep forwarding them.
