    Yeah, I think the most common method is with a handheld orbital sander with 60-80 grit. I've never personally done it though, so I'd do some Googling first.

    Modern Lodge pans are cast in sand molds, which leaves a rough texture on the inside. Antique cast iron (and higher end cast iron) is machined down to a smooth surface, which makes it easier to season and ultimately results in a more non-stick surface.

    In our current times, AKA the Great Chartreuse Shortage of 2023, I've been making cocktails with other amaros. This is probably the one I end up making the most. It's a tweak on a Midnight Stinger that splits the Fernet with Benedictine.

    1oz Bourbon
    .5oz Fernet
    .5oz Benedictine
    .5oz Simple Syrup
    .75oz Lemon Juice
    A couple of drops of saline solution

    Shake, serve up with a Luxardo cherry.

    I agree: they're taking action based on a high level, long-term business strategy.

    Unless I misunderstood this entire thread, skybrian was arguing that we should give Twitter/Facebook the benefit of the doubt that they acted for the benefit of society instead of on a business calculus (which, ultimately, is a decision of what will create the most profit), which struck me as naive.

    If you don't think that Twitter and Facebook have spent substantial resources over the last four years attempting to asses the financial risk/reward of (de)platforming Trump, I don't think our dialogue will be productive.

    He wasn't banned because Dorsey and Zuck suddenly grew consciences - these are corporations beholden to their stockholders and governmental regulations, and the calculus shifted such that banning him was the right business move.

    My default thought pattern is that all of these people are greedy assholes, and whereas you need evidence that the decision was based on finances, I need evidence that it wasn't. Neither of us has this, so it's speculation all around.

    I didn't need to add anything special for part 2 - if you were stopping execution when you saw an instruction twice (from part 1), you shouldn't have hit any infinite loops. I actually thought the problem was well structured to have you implement that part first.

    JavaScript

    My initial implementation was a typical binary search and then straightforward id calculation. After reading some of the answers here and realizing it's just a binary number, here's a more interesting solution:

    Parts 1 + 2 
    export function solvePart1(input) {
  input = input.split('\n')
  return _.max(
    input.map(seat => {
      return parseInt(seat.replace(/(F|L)/g, 0).replace(/(B|R)/g, 1), 2)
    }),
  )
}

export function solvePart2(input) {
  input = input.split('\n')

  const ids = input
    .map(seat => {
      return parseInt(seat.replace(/(F|L)/g, 0).replace(/(B|R)/g, 1), 2)
    })
    .sort((a, b) => a - b) // Array.sort() is lexicographical in JS, lol

  for (let i = 0; i < ids.length; i++) {
    if (ids[i] !== ids[0] + i) {
      return ids[0] + i
    }
  }
}
