    I'm not sure if it would be helpful for your project, but you might be interested in the concept of the grammar of graphics (https://towardsdatascience.com/a-comprehensive-guide-to-the-grammar-of-graphics-for-effective-visualization-of-multi-dimensional-1f92b4ed4149).

    I use a version of this in R as implemented in ggplot2. What is nice about it is that you can use standard text descriptions to build an arbitrary graph.

    I think I'm saying that mining on asteroids will probably never be profitable or realistic (with a possible exception of carbon, hydrogen, oxygen, nitrogen CHON once people are living on orbit). Mining on other planets might require understanding different geology and maybe different refining technology. Anything mined on a planet will likely stay there. But there just won't be any ores on asteroids because they never had a chance to differentiate into higher and lower concentrations of various useful metals.

    Metallurgical engineer here. One thing I never see talked about on this topic is how astreoids don't have nearly the mechanisms for concentrating matals into ores like planetary bodies do.

    So while there may be a higher proportion of, say, iridium on an asteroid than the average of Earth, it is pretty homogenous. You would have to refine the whole thing to get a little bit of iridium. On Earth, it may be more rare on average, but Earth also concentrates metals into ores via heat, gravity and water action so that you can mine a small area to get what your want economically.

    Metal meteoroids are mostly iron, which is cheap on Earth and of little use in space. Aluminum, which is useful in space, is one of the most common elements on Earth and even higher on the Moon,, but it's only economically mined in tropical soil that had ages of water erosion. Titanium, different process but similar story.

    Given the economics of getting to where you want to mine, mining a non-concentrated rock, and then transporting it back to Earth's for sale I just didn't see any path for mining asteroids.

    Once there's is an established human presence in space, there might be a reason to mine organics (CHON) but that is not now and not what people think of when they tout asteroid mining.

    His name will be on the ballot, but if scotus finds that he's ineligible he can't win the nomination here, so vote for him would be wasted. Well, it's wasted no matter what but you know what I mean.

    Lots of great advice. The one I might add that we failed at miserably is understanding and appreciating mental health issues. I really recommend that you educate yourself and your partner on what to keep an eye out for and check in with your kids to see how they're doing.

    ROIstat - my free GUI for R for teaching and using

    Hey, new to the Fediverse and thought I would put this out there. If you teach stats or use stats in your job, you might be interested in using my GUI for R. I hope this doesn't count as an ad, since it is free. I like how versatile R is, but I hate remembering how to type in what I already know it can do. So I wrote an app. You can tell I am not a programmer or a computer scientist (I am an engineer, industrial researcher and occasional teacher) but it works to do the basic to the moderate stats you probably use all the time. It is free. I just put some of my blog posts and books on the splash page. If you register I only send you info about the app. Let me know if you would like any enhancements. I continue to add stuff to it until I can do most of what the practical researcher would need.

    Ad firm plans to use people’s data in a maneuver to sink data privacy bill www.politico.com

    Internal emails highlight how an advertising company can use its in-house resources to oppose public policy proposals. One of the world’s largest advertising firms is crafting a campaign to thwart a California bill intended to enhance people’s control over the data that companies collect on them. According to emails obtained by POLITICO, the Interpublic Group is coordinating an effort against a bill that would make it easier for people to request that data brokers — firms that collect and sell personal information — delete their dossiers.

    Judge Chutkan says Trump’s right to free speech in January 6 case is ‘not absolute’ www.cnn.com

    US District Judge Tanya Chutkan said that she plans to put serious limits over how sensitive evidence is handled in the Donald Trump 2020 election interference case, in a dramatic hearing Friday in Washington, DC, that could set the tone for the upcoming trial. The former president has a right to free speech, but that right is “not absolute,” Chutkan said. “Mr. Trump, like every American, has a First Amendment right to free speech, but that right is not absolute. In a criminal case such as this one, the defendant’s free speech is subject to the rules.”

    Shrug maybe they could. They have yet to prove it in the real world in the US, as you mentioned.

    I like that my ISP has no profit motive and is driven solely by customer/taxpayer satisfaction.

    I wouldn't like it if it became a political football, but so far so good. I think its safe for now because it is the same network used by the fire and police departments. Comcast really tried to kill it off.

    I have a minor one... Simply Human trash can. Got tired of throwing out plastic trash cans every couple years and bought a stainless steel one. It was more expensive than one plastic, but it is going strong. It has lots of nice little design touches too, like a hole to allow air to escape so that the bag can fill the trash can cavity and removable inner frame to make it easy for cleaning.

    We taxpayers built a municipal fiber to house broadband in Longmont Colorado. Stable service, one of the fastest in the nation and inexpensive.

    I love it when a telecom asks me to"upgrade" to their service. It messes up their script when I ask them if they can beat 1 gig up and down for $45.

    This is the way competition should work. Some things private companies do better, other things the government can do better. Let them hash it out in the market without loading the dice.
