    I think you can use semicolons that way, but only to eliminate confusion when the items in the list contain commas. Eg: Today I ate sausage, eggs, and hasbrowns for breakfast; a sandwich and soup for lunch; and alfredo with chicken, asparagus, and grape tomatoes for dinner. Dammit. now i’m hungry…




  • Yeah, i think minimizing the difference in area would be the primary goal, but you’d need to add additional constraints, like also minimizing the number of times that your edges cross the true perimeter, minimizing the non-overlapping area, or something like that. I dunno for sure, but this sounds like a fun problem. I might give it a shot this weekend. I’m in the early days of trying to learn rust (after years of pure python for work and school), and I’m always looking for toy problems to test myself with!


  • For a raster image, you could count the number of true and false positive pixels and true and false negative pixels. Then use statistical metrics for binary classification, like sensitivity and specificity. I guess you could even make an ROC curve by measuring the true positive rate and false positive rate for varying number of edges in the model. I guess for a vector image you could do the same thing, just using the sum of overlapping and non-overlapping areas instead of pixel counts?











  • Get a skein of medium-weight yarn in a light color (it’s easier to see what you’re doing) and whatever the recommend hook size it says on the label. Then watch some tutorials for basic stitches. I’d start making a little pot holder kinda thing with double or half-double crochet stitch. It’s small enough that you can get used to turning rows, and it’ll work up pretty fast with the medium weight yarn to give you some nice dopamine when you finish.

    I would definitely recommended learning with just regular yarn, nothing fancy, until you get used to it. Yarn with lots of variability in the weight (as i expect plastic bags would have) is going to be difficult if you’re not comfortable with the basics.


  • The palantiri (plural) were made by the elves during the First Age when they lived with the Valar (gods), so yes they were made during a golden age long ago. They were gifted to men of Numenor who remained loyal to the Valar and Iluvatar (The God) and kept friendship with the elves. This was during a time (Second Age) in which the rulers of Numenor were being hostile to the elves, disrespectful towards the Valar, and just generally being assholes. The elves gave the palantiri to the “Faithful” of Numenor so they could still communicate with each other despite the opressive politics on the island. Elendil, fore-father of Aragorn, took them (and a fruit that grew into the White Tree of Gondor) when he fled Numenor for Middle Earth. (Elendil’s son, Isildur, is the one that cut the ring from Sauron’s hand.)

    But the palantiri were not corruption artifacts. They are seeing stones. The “corruption” you see in the movies is not inherent in the stones. It is simply that Sauron has a stone also, and you really don’t want him to get inside your head.
