  • As another scientist I do like the granularity of °F over °C for weather, but for anything else C makes more sense. It’s almost certainly just having been raised using burger units, but somehow 68°F being pants weather while 72°F is shorts weather makes more sense than interpreting 20°C vs. 22.2°C for the same decision. It’s probably cope though.

    A very helpful conversion is 10°C = 50°F & every ±5°C from that equals ±9°F.









  • The big fans you see at the front of jet engines are called compressor blades & they draw in the air. The compressor blade discs neck down progressively which, as you might’ve guessed from the name, compresses the density of the air to cram more oxygen in a given volume for the next stage, combustion. Fuel is burned here, the exhaust gases expand out the back through a series of turbine blades, which are spun by these gases to power the compressor at the front.

    The heat from the nuclear reactor causes the compressed air to expand rather than burning fuel. The issue has been getting a reactor that is light enough to fly, yet still has sufficient radiation shielding to not (terribly) irradiate the engine’s airflow. The latter isn’t much a concern for a cruise missile flying over enemy territory, but if you want to recall the missile then you’ve got a reactor that’s going 900kmh without landing gear that you need to dispose of.

    I think it’d be just their 46 silos of Jericho 3 land based ICBMs that would reach LA or other furthest cities. The entity loves telling insultingly bad lies, one of which is developing a missile with a 11,500km global reach when they only claim their regional neighbors are threats. Like they wouldn’t throw a nuclear tantrum when their apartheid collapses.

    Besides gravity bombs, their airborne component is the golden horizon (bit telling of a name) ALBM which has ~2000km of range.

    Their submarine component is pretty mid, relatively speaking; no SLBMs yet. The Dolphin 1 class is a slightly bigger German 212 class diesel electric sub with some 650mm torpedo tubes believed to be for an enlarged variant of the Delilah cruise missile. Dolphin 2 displaces 500 tonnes more due to an air independent propulsion system that gives 3-5 knots of stealthy cruising, which would take a while for a boat to get on station to launch those interceptable cruise missiles.




  • Building on this, I’d be curious to hear your thoughts on GrapheneOS as a whole. The OS recently bundled a new app “store”/repository, "Accrescent”, along with the usual basic apps like a calculator & camera. On Accrescent, the hardened fork of Signal, Molly, is offered on there. I’ve alsoheard one of the Graphene devs has voiced some chuddy politics.

    I’ve still installed & use Molly to chat with my closest friends who I was able to get off of big tech platforms previously used for our group chats, but I have been aware of the RFA/Signal connection for several years (your blog post really ties it together) & I do try to remind these friends about it. Really we just use Signal to shitpost and organize hangouts, so I’m not yet locking myself in a bunker over using it for those purposes, but all this has got me considering building a server & hosting a different secure chat service on it.

    I learned about possible Unit 8200 connections with the Matrix protocol within the past year or two, but don’t recall exactly what that entails. I haven’t heard much about Briar, but it being android only would make it a harder sell for getting people to switch over to it, so I suppose that leaves simpleX to proselytize.
