jobarion··on AES-GCM and breaking it on nonce reuse
I understand that nonce reuse is catastrophic, but I don't think I understand when it can be abused. Does the attacker have to know which two messages share a nonce? Is knowing that out of N messages, at least one pair shares a nonce already enough?
jobarion··on Show HN: Penumbra, a perceptually optimized color palette based on natural light
Solarized is fine, so is any theme that emphasizes the red-blue or blue-yellow axis instead of the red-green one. Deuteranomaly is often misunderstood to mean that red and green are close to identical (which they are not necessarily), and everything else remains unaffected. It's much more complicated than that and e.g. different shades of red / green / orange can be hard to differentiate as as well.

What's a little frustrating sometimes is that deuteranomaly affects around 8% of men, but is quite often ignored simply ignored. Using red-blue instead of red-green by default would make a lot of problems disappear.

jobarion··on Show HN: Penumbra, a perceptually optimized color palette based on natural light
I have deuteranomaly (the most common form of red-green deficiancy), and this doesn't work for me at all. I often rely on colors having both different hues and different saturation/brightness. I realize this is very likely not a goal of this color palette, but I thought I'd mention it anyway.
jobarion··on New alternatives to HSL and HSV that better match color perception
For what it's worth, as someone who has deuteranopia (red-green color blindness) the resulting OKHSL color picker seems to be harder to use than the HSL one. The OKHSV one is fine since yellow separates green and red.
jobarion··on Purelymail – cheap, no-nonsense email
Do you need to set up each *@my.tld address manually, or can you just seamlessly reply to emails send to neverusedbefore@my.tld?
jobarion··on Purelymail – cheap, no-nonsense email
When using subaddressing (e.g. example+tag@purelymail.com), can I also send from that address?

The holy grail for me would be an email service that lets me set up catch-all, with the ability to send/reply with any address I want.
