This video is great at showing non-colorblind people what some colorblind see. The woman’s son is colorblind, so she does a little interview with him, to ask him how he picks out certain colors. They also take some pictures and run them through a filter that demonstrates how he sees - to a non-colorblind person, the difference is obvious, but he struggles to tell the difference, indicating the filter does a good job of showing what he sees.

The gang must have let Charlie make the sign again.

Malcolm Jamal Warner also died within the past few days.

Worth noting is that “good” database design evolved over time (https://en.wikipedia.org/wiki/Database_normalization). If anything was setup pre-1970s, they wouldn’t have even had the conception of the normal forms used to cut down on data duplication. And even after they were defined, it would have been quite a while before the concepts trickled down from acedmemia to the engineers actually setting up the databases in production.

On top of that, name to SSN is a many-to-many relationship - a single person can legally change their name, and may have to apply for a new SSN (e.g. in the case of identity theft). So even in a well normalized database, when you query the data in a “useful” form (e.g. results include name and SSN), it’s probably going to appear as if there are multiple people using the same SSN, as well as multiple SSNs assigned to the same person.
