    Yeah, I get that, r/lfg (or local meetups) for anything but D&D/PF are pretty few and far between. I've actually had decent success going the other way, i.e., getting RL acquaintances to play PBTA / other indie TTRPGs. A few of them have explicitly tried and not enjoyed D&D, only to actually get into other games for various reasons (simpler, more abstract, etc.)

    Oh it definitely is malleable, I am mostly comparing how much effort I had to put in to do what I wanted as a DM for 5e vs a PTBA game :P

    I’m relatively new to DnD (been playing twice monthly for about a year), and I have to say it seems relatively malleable if you have the right DM.

    I find it super interesting how much time people spend hacking what they want into D&D (no shade intended). I played 5e for the first time in a few months last week, and was ... underwhelmed, though it was fun to be reunited with my old group. My interest has moved much more to PBTA and other way more experimental games, specifically because they allow way more freedom in extending / rewriting the rules, and it's generally much easier to do so. Specifically Dungeon World has move creation built into the core rule-set. I guess if your group is more into the tactical / crunch aspect of 5e, PTBA probably won't cut it.

    You seem to be conflating two things here. First, it is typically true that diesel engines emit more particulates and NOx than a gasoline engine, however this has relatively little to do with...

    In short, the amount of NOx and PM material a diesel spews out is much higher than a gasoline engine.

    Diesel is a very different compound to Gasoline and reacts differently, in part it's also caused by Diesel engines running lean most of the time (oxygen rich) while gasoline engines can run closer to optimal fuel ratio.

    You seem to be conflating two things here. First, it is typically true that diesel engines emit more particulates and NOx than a gasoline engine, however this has relatively little to do with running fuel-lean, instead:

    1. Diesel engines operate at a much higher compression ratio than gasoline engines, and therefore operate at a higher temperature. This results in higher thermodynamic efficiencies (i.e., more efficient conversion of fuel->energy, resulting in less CO2) but activates the high-temperature NOx pathway (a.k.a., via the Zeldovich mechanism). As the name implies, this tends to be much stronger at high temperatures than "prompt NO", which can be formed in low temperatures / fuel-rich situations.

    2. Particulate matter is (primarly) formed when you have rich fuel/air mixtures (i.e., more fuel than stoichiometric). The key here is that because diesel is injected later in the engine cycle, and has less time to mix. Therefore you end up with a number of "hot-spots", where the local equivalence ratio is > 1 (i.e., fuel-rich), which promotes soot formation (as well as NOx formation due to the higher temperature).

    These two factors have lead to a tremendous amount of research into HCCI (and related) engines, which attempt to combine the strengths of both engines -- this remains a very active field of research

    My friend has been putting on a very good two-part Robert Hunter tribute on his radio show (part two coming this weekend), thought you might be interested: https://archive.org/details/gt09282019hr1/

    It's a little bit between a TTRPG and a board game, so probably a bit outside of the usual suspects. Highly recommend :)

    I was given Exploding Kittens for Christmas a few years ago, and all I can tell you is that it is not fun with only two players :p. I have to imagine it's way more fun in a party setting

    I recently ran a game of Microsope with some friends, and it was a blast. It's sort of a collaborative story telling game, where the group creates an alternate history. Each round someone proposes a focus and then each player adds a period, event or scene to the time-line (not necessary to be in chronological order).

    We essentially made a history where Ancient Aliens was fact, haha

    Was just going to suggest these two. As a bonus, the 570 is officially supported by ROCm, meaning you can do compute on it (if that's something you care about)

    Side note: you're using f-strings (which I love, but are 3.6+?) but the python2.1 style class syntax

    Does anyone have experience dumping large amounts of data to disk (~100s of GB) every 5-10ish minutes or so, and if so how do you avoid I/O bottle-necking your application?

    That seems way too frequent to be honest. Even my large scale CFD runs would only dump once or twice a reservation; admittedly the time step was very small due to combustion so this still worked out to pretty good time resolution. The first thing I would do is see if you can reduce the amount of info you're writing to disk, either by decreasing the I/O frequency or pruning the data if possible.

    From there, OLCF (PDF Warning) has some good info on common IO strategies for MPI. One obvious one you may have overlooked: have an HDF file per rank and worry about combining them into the full dataset after the simulation is complete.

    Man, if you two were the same race (or maybe still, I don't know how phenotypes work in your world ;) there woulda been one heck of a united lost twins opportunity there.

    I've never had this happen to me, but then again the last character I created was for a prologue adventure to the one I was running (my friend ran it so we could play while I was getting ready to defend my PhD). I ended up making a 5e tinkerer (from UA I believe) who had accidentally created the ancient evil that the party in my adventure was trying to stop, not much overlap on that one :p

    This is a track from Mirwood Records, a small regional soul label from LA in the mid-60's. They do have a bit of a cult following in the Northern Soul scene however, which was fairly popular in the UK. There's some good discussion on Steve Hoffman's forum with some more suggestions in this vein.
