  • I’ve been working through my first playthrough of Cyberpunk 2077 - it’s fairly enjoyable, I’m glad I ignored it outright until well after big patches rolled out. There’s something very satisfying about blowing up enemies through a camera.

    I’ve also picked up Dwarf Fortress (Steam) for the first time. It has a lot of depth but has been fun to learn and try and figure out. I just flooded a section of my fortress by digging into an underground river.

    My chill-out puzzle game has been Can of Wormholes and it’s pretty fun! It’s weird for sure… but definitely fun.











  • Imagine if the straw started life as a solid cylinder and you had to bore out the inside to turn it into a straw

    This would mean a straw has a hole, yes. It would be like a donut indeed - donuts are first whole, then have the hole punched out of them. This meets a dictionary definition of a hole (a perforation). A subtractive process has removed an area, leaving a hole.

    But straws aren’t manufactured this way, their solid bits are additively formed around the empty area. I personally don’t think this meets the definition.

    Your topological argument is strong though - both a donut and straw share the same topological feature, but when we use these math abstractions, things can be a bit weird. For instance, a hollow torus (imagine a creme-filled donut that has not yet had its shell penetrated to fill it) has two holes. One might not expect this since it looks like it still only obviously has one, but the “inner torus” consisting of negative space (that represents the hollow) is itself a valid topological hole as well.
