In various industries, colors are used to differentiate between various voltages so it's obvious whether you're working with high voltage, low voltage, etc. so you can determine the necessary precautions for whatever you're dealing with (and some will also make the connectors incompatible so you can't accidentally join high and low voltage sets of wiring). I'm not super familiar with the automotive side, but I believe they use orange for high voltage and light blue for 48v.
For high level awards, there are some separate databases that list the recipients and citations. Have you looked at those? E.g. https://valor.militarytimes.com/award/5
I don't think this db will help for cases where the only existing records were destroyed in the fire -- I don't believe they have independent sources, just the sources that everyone else has access to like government records. (Not 100% sure, though, maybe I missed something.)
If those were the only records, you're probably correct, but there are sources other than the national archives that can be used in some cases such that I'd still do a search, especially for high level awards like silver stars and up.
Mastodon is federated, so users of their instance are able to interact with the wider set of Mastodon instances, much like people with @google.com emails can interact with people with @microsoft.com emails, despite both instances being separately controlled and not open to people outside their respective companies. Not having an account on an instance, in other words, is not the same as it not being accessible.
Has anyone ever watched a single person try to understand what you just said?
"I have a mastodon account. Why can't I view their mastodon posts? Mastodon is broken".
End of story. Platform is done. The fact that people are trying to say this is good enough absolutely infuriates me, and is makes me wonder if people actually know the technical level of the average user, not the programmers they work with.
Speaking of reference frames, I deal with quite a few for Earth-bound things, and the primary ones we use are ECEF (Earth-Centered, Earth-Fixed) and ECI (Earth-Centered, Inertial), which then we will often move to a relative local frame for whatever object matters.
Is the equivalent set available for Martian Nav (MCMF/MCI, I guess), or do you have different/specialized/etc. frames based on something unique to Mars.
For the rover, we're pretty much always dealing in local coordinate systems based on reference frames defined using the rover's observations of the sun and alignment of local imagery with orbital imagery. The two frames used most frequently are called RNAV (centered on the rover) and SITE (centered on where we last did a sun observation). But then there is a tree of frame transformations for knowing the location and orientation of each part of the rover with a lot of named frames (especially important for operating the robotic arm, which I also do).
