I mostly post about games I'm playing for fun and games I'm creating for work, with the odd diversion into submarine design.

It's that time again! I'm too busy MC-ing to liveskeet the day, but Rachel will!

More Shell Game as another tranche of students gets introduced to naval warfare through ABF.
Today their procurement decisions slanted towards "more missiles, please. No, more than that."

I realise it's a bit Rimmer "and then I rolled a five and a six and invaded Russia" but three nat 20s in a row?!?

Ahhh, the final two weeks of the sub design course. I always forget how manic it's going to be until we get here again.

Okay, I'm innately a bit suspicious of being followed by accounts who follow like five thousand people but have few posts or followers of their own.
But what's in it for them?

Finally dismantled the tank simulator from the garage this weekend. Which is a little sad because no more tank simulator. But on the other hand I was really missing my workshop and it was completely full of plywood tank.

It's taken me about a month to do it (the SDAC gets kind of busy) but finally have a tool students can use to assess whether they have passive range advantage over [choice of other submarine].
Sonar remains witchcraft but I think I found an appropriate compromise between realism and usability.

The word "may" is doing a lot of heavy lifting there. As I understand it those cluster bombs had two types of fuzes - one which would have sensitised and one which wouldn't - and we don't know which type(s) are on the bombs actually down there.

Just had a student ask me a question (about submerged stability) - I got halfway through the answer and was starting to think "I should really write a doc explaining this" when I noticed he had a PDF open on his laptop with a relevant diagram. Looking closer, that looks like my writing style. /1

So I am not a lawyer, but have we now established it's legal to throw sandwiches at ICE agents?

Today is External Consultancy Day so my role is limited to sitting quietly while my students have half-hour conversations with various visiting experts about how their submarine designs are coming along and asking questions.
Overhearing these chats, I could not be more proud of them.

Well, with Mamdani elected as NY Mayor hopefully that's the end of my newsfeed being full of people warning they will LEAVE NEW YORK if he's elected, and we can get on with the bit where they quietly forget they ever said that and do nothing instead.

I've just found something a d16 would be really useful for and I'm furious about it, @sebastianbae.bsky.social

Anatomy of a rapid student TTX.
One of my submarine design teams this year is working up a bombardment submarine, armed with their choice of rocket artillery (trading off range and capability with size, under a fixed procurement budget.)
Today they asked me to run them a TTX.

Quiet evening at home tonight and I thought I'd give Sea Power a go.
ASW is both a) very slow and b) basically littering. I must have relaid that barrier about four times.

DAYBREAK looks really interesting; a co-op game about fighting climate change.
Really keen to play it, interesting mechanics and I think it'll teach me useful things about climate.
This copy in Chance & Counters, in Bristol.

Bleh. I had plans to do lots of cool fun things this week and instead I've got to enjoy sitting at home with a horrible cold.
Hurray!
It's not Covid, but that's all that can be said for it. Glad I got my flu shot.

OK, House of Dynamite is an excellent example of why I don't normally bother watching movies. What a waste of two hours.
At the risk of spoilers, can anyone tell me where any of the urgency that the movie hangs on was coming from? Why was the deadline a deadline to act?

Netflix makes it really hard to screen capture these days so I'm forced to use my phone camera at the screen to highlight this egregious CGI.
That's the least American submarine I've seen in a while.
