Are there good solutions for creating (pie) charts that aren't completely opaque to people with color vision deficiencies? This article is especially egregious because I feel like they actually add to the point being made, but for the life of me I can't distinguish some of these colours. Who uses yellow (or orange, idk) for four separate labels?<p>Perhaps related, does anyone know of an overlay-type application that allows me to colorpick part of the screen (on linux)? My current solution is usually to screenshot and open the image in the GIMP or similar, but it's very cumbersome and especially if there are multiple pictures usually not worth it.
What really stood out in the article: It took a lot less time for C mistakes to be fixed vs non C mistakes. That's not saying C is great. More significantly most of the mistake based vulnerabilities took over over half a decade to be identified.
