A huge and actually informative infographic on cat colors: http://www.cedarseed.com/tuts/catcol-wp.html

That looks amazing, now if only there was a chart about cat personalities.

Unfortunately seems inaccessible, at least in France: "Access Denied - Sucuri Website Firewall - Block reason: Access from your Country was disabled by the administrator."

works in Australia... the bit about eye color is mildly interesting:

>Another cool point to consider when it comes to cat colors — cat eye colors. All kittens are born with blue eyes. At about 6 to 8 weeks of age, “their potential final eye color begins to become apparent,” Miller says. “Full brilliance is not achieved until a cat reaches maturity.” Full maturity can take one to two years, depending on the cat breed.

Aren't a lot of brown eyed people also born with blue eyes, changing a few weeks later?

Both my kids were (I have blue eyes, mother has brown). Disclaimer: Sample set of 2 may not be representative of the general population :)

Interestingly enough, blue eyes bear low levels of melanin but that melanin is what makes eyes brown at higher levels: the blue color is due to Rayleigh scattering!

Green eyes are so because of a combination of lipochrome (color source of amber eyes) for the yellow component and Rayleigh scattering for the blue component.

Hazel eyes have non-uniform melanin in low to moderate amount, which combined with Rayleigh scattering makes the eyes change color depending on light conditions (mine can go to greenish-almost-blue to deep green to brown with speckles of gold, and any intermediate combination of those).

Yep, this. Blue eyes are blue for the same reason that the sky is blue!

Same for some of us, that are born with gray eyes and color starts appearing weeks after birth. And eye color can change during childhood, from blue to green or hazel for example.

Weird... it doesn't work for me either from France, but it works from Belgium. I wonder why they would block just France.

Obviously since they don't block Belgium it's not like those American newspapers who block EU visitors to make a statement against GDPR.

Edit, here's the archive.is version: http://archive.is/GjLRp

Not just France. Russia is blocked too.

Blocked in China too.

Works in the UK

Russian IPs are also blocked. Oh well, I'm getting used to it.

But I don't understand why a cat magazine would block access from certain countries.

The only reason I find is a threat of DDoS and/or script kiddies with penetration bots / automated tools.

Same story when visiting from Russia.

When I read this, I thought it was something to do with a nice looking `cat` command. Oh well, it's HN

Then check the grcat tool :)

Thank you! Will do.

Check out bat, it is almost a bit over-designed, but features line numbers, syntax highlighting, and paging without piping to less/more out of the box:

https://github.com/sharkdp/bat

Came here to add that. I'll add it is written in Rust by same author as fd utility (find replacement)

The old BSD cat already has line numbers, which led to Rob Pike's 1983 presentation titled ‘UNIX Style, or cat -v Considered Harmful’: http://harmful.cat-v.org/cat-v/

If I was the author of bat, I'd consider inserting that link into the README, just as tongue-in-cheek :D

Check out vimcat which is part of the vimpager project:

https://github.com/rkitover/vimpager

Basically cat with vim syntax coloring.

> When it comes to cat colors and coat patterns, here’s a mind-blowing fact: All cats are tabbies.

Shouldn't be that surprising if you know what their immediate ancestral species looks like [1].

This is only tangentially related, but Veritasium has a fantastic video that discusses the genetics behind the random color patterns of calico cats: https://www.youtube.com/watch?v=BD6h-wDj7bw

> If you’ve studied cats for very long, you probably know that calico and tortoiseshell cats — those with both black and red coat colors — are female. That’s because the orange gene is carried on the sex-linked X chromosome.

Thats pretty cool, at least now I know the random cat thats been visiting me is female :)

Male calicos exists[0]. It happens when it has XXY sexual chromosomes (trisomy).

This is either an advert for NoJS, Wikipedia, or both.

> By red, we mean what is commonly called orange.

How pretentious. Why not just say orange?

https://en.m.wikipedia.org/wiki/Orange_(colour)

If this were a "lost cat" poster, I'd agree, but for an explanation on cat color genetics, I think the correct term is appropriate.

We call people with orange hair "redheads" so, I don't think this is that different

Orange is a relatively much younger word than red (Middle English versus Old English with direct lineage from "Low" German/Proto-Germanic/…/Proto-Indo-European), deriving from the fruit (rather than some may assume the other way around). Orange entered the English language from French royalty (who could afford imported oranges), so arguably Orange is the more historically pretentious color word.

click on “manage preferences” on the cookie popup, and then “list all partners” in tiny text link near the bottom.

Why do they have so many partners?

How could they reasonably partner with them?

Why don’t they have “uncheck all”?
