They never thought to test a condor riding a bicycle. Sounds like flawed experimental design

but blender isn't CAD, right? it's not a replacement for cad software (such as openSCAD, autodesk, etc...)

I think most of our ability to judge relative distance is based on our brains judgement of lighting, texture, inference, and sound. While having two eyes helps a lot, you can still navigate a complex office environment with one eye closed.

I don't think the ceramic fiber blanket is necessary. I made my own reflow oven (PID temperature controlled) and was surprised to find that my roommate was able to reflow a PCB with his completely unmodified toaster, just popping the P

One thing that isn't being discussed here is that if your neighbors don't do this, you'll be the only home left on the block. That's a bit depressing, to live deserted next to a bunch of burnt down homes. You can sell th

Are we even helping them at that point? It's just another censored search engine. They already have that.

You needed to make that heatmap translucent and overlay it on top of the rpi with a diagram pointing to each chip and what it does. That would have been a super cool graphic.

What about making a bike out of wood? It would have a lot of friction, sure, but it might be better than walking?

I think there's a third dimension: how much you've given up. So my thoughts are like #4, but with the undertone of "who am I kidding, of course they don't care, what can I do?". This is perhaps the most dangerous re

I mean, it's pretty incredible and coincidental that we evolved brains this sophisticated in the first place, out of a totally random process with selective pressure. After 13 billion years, I mean I think it's reasonable progress

Does this remind anyone else of the lottery ticket hypothesis deep learning paper that was published recently? [0] I think the gist was that neural networks are usually much larger and more connected than necessary. The paper provided an al

Actually, ads on facebook are surprisingly beginning to look like this for me. I've found myself going from hating ads to finding them actually surprisingly interesting, and things I would have wanted to look at anyways (like, for exam

It wouldn't make sense for your phone to be part of a P2P network. It's only connected to your radio tower, and not really anything else. Also, you could define a maximum file limit size, and at that point your phone would be cons

It's interesting to see that the old yiddish typewriter layout is actually not identical to the modern hebrew typing layout. While they're almost identical, about 5 letters have been swapped: ח, א, ס, ף, and ב is just removed from

The windscreen has wipers, on the Tesla model 3, I don't think all the sensors have wipers... so that's an issue.

He's suggesting making the decision once, per-browser, not per-website, whether or not to allow cookies. Then the browser can include this information in the HTTP header, so the website never needs to ask you.

By the way, the difference between the safety factors of driving and flying are not quite so straightforward. This is one of my favorite charts, which shows that per-mile, flying is safer, but per-journey, driving is safer (which makes some

Frankly, it hasn't even been a week. Thousands of flights happen every day, and these two accidents were 5 months apart. If it takes 2 weeks to make the decision, that actually sounds quite rushed. In the meantime every pilot on the pl

You can also increase memory usage for faster software, as is the case with memoization and lookup tables.

Okay so I was confused by this too. I think it is especially especially deceiving because it specified that the ball only moved in one axis of motion, but it's actually two (falling, and then rolling over). I also tend to get very frus

I think there's more to life than settling into a fixed set point. Life is interactive: you can improve your experience by putting in the right kind of effort and getting lucky. For example, the author wrote this article and made a str

This doesn't look that more space efficient than a normal parking garage. I'm sure better implementations could exist that would make it way better. Also... I'm imagining having to wait in a huge line during rush hour because

I think technically the mode is one of the middle buckets, it looks slightly taller to me. Anyways, it's a histogram, so the x-axis is split into buckets. The bar all the way on the left is likely some range of hours from 0 to whatever

1g is the strength of the Earth's gravity, so aren't we always constantly experiencing 1g downwards? Like, every time we jump or lift our feet?
