This is a topic I keep revisiting. It's constantly evolving, with new laws in different parts of the world happening pretty often. And also there's a lot of grey area with vague or incomprehensive language that hasn't yet been tested in courts.

I recognize that it's a bit of a niche topic, but I think there are a lot of us at Tildes who have to think about it. After all it potentially impacts anyone maintaining or building a non-platform web presence. It also applies to less obvious things like running an advertising campaign that involves media requested from a server you control (which can therefore potentially log requests).

For my part, I've needed to research laws relating to PII in order to come up with policies and practices in various contexts. In broad strokes it's pretty simple but as you get into details what I continue to find is that there are a lot of conflicting opinions both from professionals and lawyers. A lot of it is still open to interpretation.

I'm wondering what kinds of experience other tildenauts have around data protection and PII? Have you implemented solutions? Do you wonder about it for your own websites? Have you been involved with it at companies where you've worked? Do you have questions about it?

Lately I've been taking an interest in American westward expansion and trying to get a better understanding of how the lines were drawn on maps in the past. Can anyone recommend a good video or interactive visualization that I can scroll back and forward through time to see the changes in detail?

Things I'm particularly interested in tracking:

• Indigenous lands (specifically how the boundaries of traditional/ancestral lands evolved into modern-day reservations)
• European claims like those of Britain, France, and Spain
• What was considered US/Canada/Mexico territory vs. no man's land or frontier at different points in time, from the governance standpoint of each of those nations
• Large and rapid settling movements like the Mormons into Utah, Oklahoma land rush, California gold rush, etc.
• Other factors like homesteading programs (I don't know much about this) and the transcontinental railroad, confederacy borders, trail of tears, etc.
• Notable battles/massacres marking bloody land disputes

I mean I guess that's a lot, this is basically "tell me about all of American history." 😂

I feel like I have a pretty decent grasp of the general political timeline and important events, I'm just realizing lately that I don't have a cohesive mental model of how it all fits on a map and changed over the years. I did find the Wikipedia page on Territorial Evolution of the United States to be interesting but it's a bit overwhelming and not very digestible. It contains this animated gif, which is awesome but I can't scroll through it at my own pace, and it's USA only.

I was contacted by a recruiter regarding a job in my field but they wanted someone with data analytics skills. I'm taking this as a sign that I should improve my skill set. Does anyone have advice for where or how to start with a very small budget?

Thanks for your help.
