Here is some context: Early in the aphantasia discourse, someone asked a group I was in to do a mental exercise: Imagine an apple. Can you tell what color it is? What variety? Can you tell the lighting? Is it against a background? Does it h

Recruiters use automated tools to scrape LinkedIn profiles and send what amounts to customized spam.

On the one hand, yes. On the other hand, clock time is entirely a social construct whose whole purpose is to coordinate social and business activity, so it should be specifically designed around social customs in order to serve that purpose

Aha! That was a bonehead miss on my part. Very nice, and very slick interface. :)

EDIT: Author has pointed out that the interpolation mode can be changed. Very slick! It looks like this is interpolating in HCL or HSV space— that tends to produce unexpected results, including intermediate colors with unrelated hues (pink

Pixar used RCS at the time. Problem is, when you run `rm -rf /`, that deletes the RCS directories as well.

The failures will continue indefinitely, until Tesla decides to use stereopsis for ranging.

And that's the biggest doublespeak lie about it. The web is already open and decentralized by its very design, and that openness and decentralization is a major reason for its incredible success. Web3 people want that stuff not to wor

Victim-blaming comments like this make me see red. "The fact that I am able to exploit these people means that I am entitled to" is everything wrong with Silicon Valley.

Tesla autopilot use nowhere near competitive with a human driver, no matter what they claim. I'm bullish on self-driving in general, but Tesla's misrepresentation of their self-driving capability has always been just shy of &quo

You're completely free to decide you're unbothered by it in your own particular application, but it would be unhelpfully misleading to other readers to say that a 10^6 performance difference is "negligible", or that they

Author here. The particle filter has its own strengths and drawbacks. It makes more sense to use a particle filter in situations where the state search space is highly nonlocal and/or nonlinear, for example locating a drone on a map by

The article says that there is an audio cue. The cow will hear a beep long before it gets zapped. It's the same as for invisible fences with pet collars.

If a dollar is defaulted, I'm not sure it's accurate to say that one dollar is destroyed (as opposed to moved), let alone ten? If the borrower defaults, it is the same as the borrower owing the depositor $1 (the bank is in a sen

Again, maybe dumb question, but what sense is "every dollar leveraged 10x"? Also in 2008, it looks like money velocity decreased during the recession (as it's been doing almost monotonically since the mid 90s). It looks like

Maybe a stupid question, but if the velocity goes up, couldn't/wouldn't the Fed contract the supply? It seems like having large supply is desirable/correct when velocity is low.
