    Dude. Killer piece. So many inner-circle first-hand accounts here. Source density is off the charts: details, quotes, no fluff, just nonstop mayhem.

    I seriously had no idea how much those close to Trump truly detest him. Why did I assume they were mostly rabid devotees? But no one respects him, and clearly many no longer even fear him, so I take it they either expect his downfall or want it so badly they’re willing to risk anything for it.

    And maybe it’s not even heroism. At least, no one in this story displays a shred of virtue. These are backbiting cynical bastards, a carousel of political thugs. That really makes reading this piece feel like watching a ruthless mobster’s former crew participate in a ritual assassination.

    So, if you’re in need of some catharsis: first vote, but then come back and bogart this article. It’s the good shit.

    Their genetics have sacrificed nearly every aspect of basic resiliency for maximum speed on the plains. Most of the work caring for horses is keeping them from accidentally killing themselves. Full disclosure: I worked as a stable hand as a child in exchange for riding lessons. Will never ever own a horse.

    More abstract means simpler, but it’s easy to get lost if you weren’t ready to have concrete examples taken away, so examples are offered for each translation below.

    1. A chu space is a “binary relation” between two sets. In other words, it can be represented as a matrix of pairs. E.g…

    Think of an ordinary table, where each cell relates a row to a column. A common application of chu spaces is computation, so imagine how rows could refer to possible states of a program and columns could represent the events transitioning one to another. Each cell would then represent an incremental change to a particular state.

    2. Dropping the “closure requirement” means a given point need not be reachable from every other possible point. E.g…

    If on a computer you delete a file, but decide instead you wanted to rename it, you might not be able to get to the desired state in a single logical step. First you may have to reverse the last step (deletion) then execute the next (rename). So the set of points representing these steps wouldn’t be closed topologically.

    3. Dropping the “extensional” requirement means that points can be considered distinct even if their contents are the same. E.g…

    In the file system example above, if you rename the file to the current file name, even if it results in no change to the current state, it can still be considered a valid transition to a distinct state.

    4. Dropping the “two-valued” requirement means we don’t need to know for certain whether or not a point is included in a set. E.g…

    First, we say two-valued just to be inclusive of yes/no, T/F, 0/1, -1/+1, and other dyadic pairs. Not requiring it means we can work with values between the two extremes, such as the probability that a point is included in an open set. This is particularly relevant to quantum applications where nothing is certain because particles simply pop in and out of existence and generally behave like assholes.

    5. The static matrix of #1 is a single slice of a more dynamic "continuous function” that lets us describe how a chu space transforms over time. E.g…

    In the file system example of #3, we wouldn’t want to literally represent each state and potential event in a matrix. Instead, we would consider the static matrix of as a “snapshot” of a larger continuous series of file system changes. (And it so happens that this is how incremental backup and version control systems tend to work.) Instead of fixed sets we would then have complementary functions mapping states forward to an event and mapping events backwards to a state.

    (Note for the mathy: the above is supposed to be layman’s terms but if there’s a major inaccuracy please correct me.)

    I commute in a similar looking but less insulated Columbia Watertight II (Gray, M) and the sleeves are at least 2 cm longer than any other shell I’ve owned (a pleasant surprise for someone with long arms).

    It’s narrower at the waist than the torrentshell but similar at the hip, not as insulating but lighter, and it’s a bit stiffer material (e.g. headwind doesn’t press it against your skin as much as slinkier shells). This style of jacket isn’t specialized for cycling so it does bunch a bit in the front and could ride up in the back if your stance is low. And the hood isn’t removable to accommodate a helmet, so you sometimes have to shake the hood out at the destination.

    But it’s dry, comfortable, and has held up for 5 years of commuting. 🤙
