  • A persistent assumption about advanced interstellar travel is that engine efficiency is monumentally better to the point that the “tyrrany of the rocket equation” is no longer a factor, and extra mass can be carried without absolutely exploding your fuel requirements into absurdity.

    If adding 10kg of payload didn’t mean also potentially many times more mass of propellant we’d be sending up more robust spacecraft, no question.

    Well, yes, very clearly it’s a “man on screen said it” situation, but it’s not like that’s new.

    People who repeated “ground control to {insert name}” to get the attention of someone whose mind was elsewhere didn’t believe they were actually addressing an astronaut. It’s an idiom born of the current cultural zeitgeist.




  • Generally speaking it’s considered bad practice for a GM to call for rolls that literally no one in the party can succeed at, but as with anything in tabletop roleplaying there is nuance.

    There could be a narrative reason for the player to not know just how difficult something is and you don’t want to give it away by just telling the players they can’t succeed. If the most capable member of the party rolls a 20 and fails then the “reward” is the narrative of the attempt and learning what you’re up against.

    Or maybe someone in the party could succeed but for whatever reason the child-prodigy wizard with a strength of 8 wants to try lifting the portcullis. It wouldn’t make any sense for them to actually do it.


  • Full-size is objectively superior, everything else is a mitigation for sub-optimal circumstances.

    If you have reduced desk space and need to conserve your keyboard size to allow more room for a mouse then absolutely, pick as small a keyboard as you’re comfortable with to get sufficient mousing space.

    Anything beyond that is subjective personal preference, which again I have no qualms with, but calling it better without further qualification is going to invite incredulity.








  • I’m with you 100%. The people downvoting you must live in some idealized fantasy land where public transit is effective and rental cars are easily available and affordable.

    Like you, I live in the real world, where public transit is a mess, the rental market is completely overwhelmed, and charging infrastructure is spotty at best. So I went with a plug-in hybrid vehicle when I needed something new after my 11 year old Lancer got rear ended and written off by the insurance company. Enough electric range for all of my daily driving, but also a gas tank for when I need to exercise that 2% of my driving routine and go farther afield.

    It’s been over 500km since I last filled the tank and so far it’s still full.







  • There isn’t much difference at all. Neither should have a cap.

    Data moving across a network doesn’t have any per-unit cost to the people operating the network. Whether you use 5TB or 5GB doesn’t impact the bottom line of the ISPs at all.

    The only justification for a data cap would be if they’ve overprovisioned their network and sold too many people plans that are too fast for their network to support, so they need to disincentivise people from actually using it. Even then that’s pretty shaky justification.
