Since you don't seem to have commented on the article without reading it, my comment was not addressed to you. I'm not the article police; if you find something too long to read, decide not to read it, and move on with your life, we have no quarrel.

Honestly, I don't even mind the folks who do comment without reading. Comments are free, do what you like. I just find it mildly hilarious that 100% of the comments are about (the first) 3% of the article.

This comment section is the most absolute proof I've ever seen that absolutely nobody reads the article before commenting.

Hint: it's not about integer types at all

I'm curious how this can both avoid the average-of-averages problem (presumably by using the original full-rate data to compute multiple aggregates) and also supports backfilling. Is there a danger of the full-rate data expiring and having a different behavior for backfills past that horizon? Or am I wholly misunderstading both these features?

I'm ... shockingly interested in this bank letter ghostwriting thing. Could you say more?

Congrats on the launch!

Yep and yep. Not basic at all, this stuff is only simple once you already know how it works.

AIUI, RSUs are treated as normal W-2 income when they vest.

What about ion engines? I'm extremely not sure I have this math right but NEXT claims 4190 second ISP [0]. Plugging that into the rocket equation I get:

  iss_mass = 419600
  sep_isp = 4190
  delta_v = 5748
  htv_payload = 3310
  falcon_launch_cost = 62000000
  total_mass = iss_mass * math.exp(delta_v / (9.8 * sep_isp))
  fuel_load = total_mass - iss_mass
  dragon_launches = math.floor(fuel_load / htv_payload)
  total_cost = dragon_launches * falcon_launch_cost
I get:

  Total vehicle mass: 482,646.89 kg
  Fuel to add: 63,046.89 kg
  Dragon 2 launches: 19
  Total cost: $1,178,000,000.00
Not what you'd call cheap but at least in the realm of the possible. I'm assuming the ISS' solar panels (~120 kW [1]) is sufficient to power the thruster, that a dragon launch costs no more than a falcon launch (certainly false), and that the ion engine is already on board the station.

I don't know why they sell the 3mgs either because nothing less than three of them has any effect on me. Thank god for 10mg tablets.

Hey, that's a really useful reference, thanks. I actually learned something about OCaml from it!

At least for the comet pusher, the tech needed to put a non-trivial number of humans on Mars has a ton of overlap with the tech needed to divert potential impacts.
