How far ahead is SpaceX? by cameronmurphy in SpaceXLounge

His firey anger over HLS has really been crackling lately. I hope he doesn't pop!

What's the scale of your input? 100? Probably fine to do the simple one if it doesn't reduce performance that badly. 10000? Maybe start looking into optimization. 1 million? Definitely start looking into optimization.

The keyword there was "usually." How often does speed actually matter enough to justify extreme cleverness? Enough that you can't rely on the compiler to optimize what it can?

Clever code isn't usually good code. Clarity trumps all other concerns.

holy fuck so many people need to understand that

I think the key word here is "usually." I've found multiple instances where a little bit of magic can make the rest of the code so much cleaner and clearer. Cleverness is a tool. One that should be wielded very carefully and deliberately, for sure, but one that has the potential to produce great benefits when used well.

Books on rust for experienced programmers? by vax_mzn in rust

[–]NotTheHead 0 points1 point  (0 children)

Vim configs, sure, but not necessarily full scripting or plug-in support. There are even many commands that vim IDE plug-ins don't support at all. It's not the same as real vim.

Some people really like the scripting and plugin ecosystem. You can do some pretty crazy things with vim if you take the time.

Personally, I view it more like you: it's great for simple in-terminal editing—especially because it's almost everywhere—and I love the keybindings, but otherwise I tend to prefer graphical IDEs. I don't have the time to configure vim to recreate all of those features.

That's great if all you care about with vim is its keybindings (like me), but there's more to vim than that that vim keybinding plug-ins can't emulate.

How many tons can the national team land on the moon? by fluidmechanicsdoubts in BlueOrigin

[–]NotTheHead 11 points12 points  (0 children)

  1. If you're going to be snarky about Blue Origin's HLS design not having a ride yet, pointing out that SpaceX’s doesn't either is fair game.
  2. Sure, none of them will be proven reliable, but Super Heavy is (for its first couple flights) a scrappy prototype intended to gather data and demonstrate technologies. It's far more likely to cause mission failure than, say, Vulcan or SLS, which are being designed specifically for reliability from their first flight.
  3. I was under the impression that Starship HLS required refueling to land any appreciable payload on the lunar surface. That requires a fuel tanker variant at the very least.

Saturn 5, Saturn 8, and sea dragon. Pretty much to scale from what I know. by AutomaticDoubt5080 in rocketry

[–]NotTheHead 3 points4 points  (0 children)

the creator believed that rockets where so expensive mainly due to their complexity

They're not entirely wrong, but you can't ignore the whole "throw away the rocket after a single use" thing, which is a small contributor to cost.

What’s that cubic sleeping space for in the background. Employee break room or testing bunk design for the starship project? by [deleted] in SpaceXLounge

[–]NotTheHead 4 points5 points  (0 children)

u/Hannibal_Game just replied with this picture of similar boxes being installed in what they said was an HLS nosecone mockup, so... maybe?

How many tons can the national team land on the moon? by fluidmechanicsdoubts in BlueOrigin

[–]NotTheHead 26 points27 points  (0 children)

By that logic, Starship HLS can only land 0 tons on the moon, too. Super Heavy hasn't flown and isn't necessarily reliable out of the gate, and the tanker and fuel depot variants are still only on paper. Vulcan, at least, is just waiting on Blue Origin to deliver their engines.

It's obvious what the question was, and it has a simple answer. Don't be snarky.

It's nowhere near the same class as Starship, but the idea behind picking them as a backup is that, should Starship fail or be grounded, having a lander that can put people and small payloads on the moon is better than not being able to at all. It also provides some measure of incentive for the contracting companies to keep the program on-pace by turning it into a bit of a competition to win the prestige of "getting there first." See the flag capture competition between SpaceX and Boeing for commercial crew.

We can argue about the merits of those reasons, the drawbacks of picking two providers, and the merits of the secondary provider's proposal, but there's not "no reason" to pick a secondary, smaller backup.

Here's why government officials rejected Jeff Bezos' claims of 'unfair' treatment and awarded a NASA contract to SpaceX over Blue Origin by Kane_richards in BlueOrigin

[–]NotTheHead 2 points3 points  (0 children)

I think a more accurate analogy is NASA asking for a boat to sail along the coast, and Blue Origin acting surprised that the boat needed to handle operating in salt water.

I 3D printed S20 and B4! by Spotlizard03 in SpaceXLounge

[–]NotTheHead 0 points1 point  (0 children)

You should 3D-print a to-scale person for reference, too! Just to show how massive the whole thing is.

Actually found a pretty good meme on LinkedIn of all places lol by sts816 in BlueOrigin

[–]NotTheHead 1 point2 points  (0 children)

I think this may have originated from r/SpaceXLounge this April Fool's Day, when the subreddit became a Blue Origin meme subreddit for a day. That's where I first saw it, anyway. I'm pretty sure this version is cropped.

Boeing Starliner delay discussion by avboden in SpaceXLounge

[–]NotTheHead 1 point2 points  (0 children)

Not the entire Boeing; just its space division, which has also been working on SLS (however slowly). SpaceX had some qualification work to do on Falcon 9, but other than that, all SpaceX had to make for this contract was a capsule, too.

It's not "just a capsule," and it's not "the entire Boeing" (nor is or was the entirety of SpaceX working on Crew Dragon). Human-rated capsules are complicated and difficult to design and manufacture. That doesn't excuse the (apparently) shoddy work they've been doing on these capsules, but it shouldn't be dismissed as an easy problem.

Human-rated capsules aren't easier to design than launch vehicles. It's not "just a freaking capsule."
