That's the chromostereopsis effect, that is caused by how our eyes refract different wavelengths of light https://www.youtube.com/watch?v=udpEnJXVWEk

You said it wasn't from Synthet, but they did release a video ~2 weeks ago which talked about exactly that. Super interesting, whether it's the correct video or not!

Click "Editor", then click "Add a brush".

That's an interesting one, because it's misused more often than not, to mean what you are suggesting.

It's actually meant to say if someone provides an exception, e.g. "No parking on Wednesdays", then that proves the existence of another rule, e.g. "Parking is allowed". Since an exception, without a rule, makes no sense.

But, in my experience, people do use it to mean "Oh, this one thing is wrong, but that proves everything else is right", which does not track.

267, I was going pretty strong and had about 2 minutes racked up, until I hit a wall, and couldn't think of anything else. Thinking in groups helped the most, e.g. reptiles, flightless birds, african animals, etc.

Extinct animals also work, including the dinosaurs!

Is there any chance you'd be willing to share that tool? :)

A tool that uses face-api to find the movie character you look the most like. Everything runs in browser, without any data being sent to the server.

Moore's Law roughly states that we get a doubling of speed every 2 years.

If we're 6 orders of magnitude off, then we need to double our speed 20 times (2^20 = 1,048,576), which would give us speeds approximately in line with 40 years ago. Unless my understanding is completely off.

It seems to me that it comes down to how the day of the week was picked.

If they picked a random day of the week, and there was only one boy, then there is only a 1/7 chance of a boy being born on that day.

If they have one boy, who was born on a Tuesday, and that is why they picked the day, then there is a 100% chance of a boy being born on that day, so no additional information is conferred.

Hell yeah, this is great. I made a similar, but much worse, thing a while back

https://jammaloo.com/DealWithIt/

It uses face-api.js to find the face, and then move the sunglasses over it. It's about a 5 meg model, so it's pretty slow to load. You can customize with a URL, or drag and drop an image on. Resizing the browser also moves the glasses around.

Very happy to see someone take the idea way way way further!

Add the -n flag to echo

echo -n "To begin with, for example, and to make sure your SHA-256 hash function is working, the hash value or checksum of this sentence, from capital 'T' to concluding colon, expressed in hexadecimal, is:" | sha256sum

Echo is automatically adding a newline

Not disclosing it to postfix is the biggest issue I'm seeing people talk about. From the article they reached out to three of the biggest individual vendors, but there's no indication of them disclosing it to postfix or any of the other providers of mail server software.

In the article they even mention that postfix is affected, and show it as being the most used mail server online, by a large margin.

Worth noting, that the myhouse.wad file, at least for me, does not contain the full level. You instead need to use the myhouse.pk3 file.

As a heads up, the download links to the technical preview builds of Docker seem to be incorrect on that page https://docs.docker.com/desktop/wasm/. The Windows, Mac OS Intel and Silicon each point to https://www.docker.com/download/wasm-preview/linuxamd64deb which is the linux build.

The article linked by the OP has the correct links.

There is a great youtube channel that tests out different energy storage and harvesting setups, a lot of them focused around water.

This is one where they use solar to pump water to the roof, and then use the potential energy overnight: https://www.youtube.com/watch?v=CMR9z9Xr8GM

The icon isn't the photos app icon, although the general shape is similar.

>Add details cautiously. If the content or shape is overly complex, details can be hard to discern. Icons at all three sizes should generally match in appearance, although you can explore subtle, richer, or more detailed additions at 48×48 pixel size.

I believe that example is meant to be an example of a bad icon, as it has a complex shape with lots of different textures.

On August 22, 1994, David Donoghue threw an egg out of a helicopter onto a golf course in the UK, from a height of 213 meters (700 feet). He now has the record for the longest egg drop without breaking in the world (all without an outside structure for added protection!). https://www.scienceworld.ca/resource/egg-drop/

Eggs are evolutionarily designed to survive falling out of nests and perches. You assume that the egg is dropping onto a hard surface, but there is no mention of that in the puzzle.

That's even assuming it's a chicken egg, but other eggs may be more resilient. It may not even be a biological egg, but an artifically designed egg, that is resilient to drops onto harder surfaces.

I've been playing with this app for a few minutes, and it does appear to save everything in plain text files, so adding it to git would be straightforward.

I'm currently saving into a dropbox folder, which gives me automatic syncing.
