    I thought it compressed a lot of events into its rather long timeframe, so some scenes that built up scale and atmosphere are quite short compared to the equivalent scenes in the first movie.




  • G11 is a super interesting clockwork design. THere's also the P90. Both of them have a circular bolt (or a circular... Bullet travel mechanism). Because I'm probably using a longer round, that would use up a lot of space, so I'm looking to pare down the mechanics of it (e.g. compared to the G11, reducing parts, paring down reciprocating gears to just minimalised arms etc). The g11 wound up being quite tall and boxy given the size of the round fired.


  • Filters do need to get replaced over time. I was going to use a silicone flap with an external plastic housing that bites the silicone when you submerge the gun. It's not going to stay super sealed by any stretch, especially if you get deeper, but it will help quite a lot despite also allowing the system to breath. There'd be a separate thin filter for silica particulates (doesn't have to be N95). I think the whole housing would actually be pretty cheap as an injection mold plastic (Nylon 6, no need for glass fiber because its a little seal that takes about as much pressure as a snorkel) (Nylon 66 doped with about 30-40% glass fiber is "composite" in gun language, idk if carbon fiber as a product has made any headway into gun production). Basic parts list is silicone circle, the water filter (a plastic clamp that depresses if its under too much outside pressure, biting the silicone and stopping it from flapping), a relatively thin breathable filter (it only needs to work when the gun is firing, unlike an engine filter that has to run for hours at a time), and a plastic housing to hold all three together, and they slot in at the front of the gun.

    I was looking at goretex for a "tacticool poncho" (with internal ridges, to allow air to move up past your torso and out behind your head!), but it's actually kind of annoying to source particular patterns and it while it does breathe a little bit, probably not enough for this purpose:

    The other breathing membrane (basically, a one-way silicone valve that rides with the bolt's guide arms) basically pushes most of the internal air inside the gun out through the barrel while the bolt is unlocked. The idea is every time you shoot, you vent a bunch of the internal warmed air through the barrel, pushing out the very hot air from firing as well as various acidic propellant leftovers. Obviously, this venting also needs to pull air from somewhere, so it pulls cool outside air through the above filter. My hope is this breathing mechanism is actually quite cheap and light, with only a mild increase in complexity. No idea if it would pan out or have an effect, but that's the idea. Uses up the spare volume in the front part of the gun where it's mostly barrel, guide arms etc (of which there shouldn't be much, but having round components in a rectangular-ish chassis means you get spare volume, and the straight line from the rear of the gun to the front will leave some space too).



  • Sometimes. I have a hard time when to prioritise my own needs against other people's, so I wind up vacillating between very meek and belligerent kinda randomly. Especially when it comes to social needs (e.g. if it feels like someone else is dominating a conversation with their topic of interest, and I have something I wanted to say about something 3 minutes ago but the person hasn't stopped talking, idk what do).

    I had a hundred or so pretty good interviews afterwards.

    I haven't had that many interviews and I've been job searching for most of my adult life. I feel like I'm not improving fast enough to do well before I'm 70. If I'm improving at all
