SpaceX has gotten reduced cost engineering since its inception, due to telling their employees that the entire purpose of SpaceX is to put humans on Mars. Everything was about maki…

Several things: * There are many useful ways to handle it properly, and your choice depends on your program's constraints. The very small amount of friction (once you're used to it…

To add to this excellent explanation: Rockets have a fundamental problem. They need to go absurdly fast. If you have a rocket that can reach speed X, to go faster than X you need t…

Analysis video by Scott Manley notes that other comparable tests did not have visible fire at all, so it seems it started lower on the rocket and that the upper fire ball was eithe…

It is supposed to tilt away from the launch tower immediately, you can see this on previous flights. This keeps the engine plume away from the chopsticks and top of the launch towe…

Summary from my watch: - Launch roughly on time, after a scrub yesterday. (Sounds like the scrub was due to ground equipment, most notably the water system.) - Initial ascent was g…

The Witness is, in my opinion, simply one of the best games ever made. There are many layers to the game, and moments of insight that the game leads you to, but also trusts for you…

I agree, though I think the real winner here is the customers. The New Glenn 9x4 has a higher targeted payload capacity that an expended Falcon Heavy. Mission design takes years, a…

No law in relation to pennies has changed. The executive branch has simply took the law stating the mint should create as many pennies as necessary, and decided that the necessary …

I've managed to visualize a Klein bottle in 4d. I easily visualize 3d objects. However I can't really do color - I startled myself recently when I briefly saw red. On that aphantas…

1. It still took nearly 7 years to after JFK's speech in the 60s. 2. The institutional knowledge of working directly on the Apollo program has largely been lost in the US, and cert…

Payload capacities to trans-lunar injection (source wikipedia): SLS Block 1: >27,000 kg (59,500 lb) SLS Block 1B: 42,000 kg (92,500 lb) SlS Block 2: >46,000 kg (101,400 lb) Vulcan …

SpaceX's lander bid was in large part so competitive because they were already planning on developing 90% of the technology anyways. Low earth orbit service was developed for NASA,…

> Because most open source projects don't attract anywhere near those levels of donations. It's not unheard of. Eg, Blender earns $261,360/month. ( https://fund.blender.org/ ) Comp…

It's not an optimization. What gets evaluated via the lazy evaluation is well defined. Control flow which has a value defined at comptime will only evaluate the path taken. In the …

The computer is a machine, and modern ones are complicated. When I am programming, I want to precisely control that machine. For me, simplicity is measured in how complicated it is…

The lack of including the before photo in the article says something. There was clearly real, albeit minor, damage done. The fees seem high for such a small blemish. Automated rule…

It isn't. Consoles at this stage are general purpose computers with hardware and software explicitly designed to prevent consumers using it as such. If consumer rights had any real…

I'd say it's better to call it a unit of counting. If I have a bin of apples, and I say it's 5 apples wide, and 4 apples tall, then you'd say I have 20 apples, not 20 apples square…

I've been playing and enjoying this game since it was first posted on hn. Doing this is absolutely key to getting a good score. Eg, for the final answer in today's puzzle, I had th…

This post seems to be missing an additional opportunity: Zig's build can involve go build! Use Build.addSystemCommand, have it depend on library step, and have the install step dep…

The Apollo program had a wartime budget and a wartime risk tolerance. The US and Russia were at war, though they did not directly engage with each other due to the threat of mutual…

Methane flare. Liquid methane will turn to gas as it warms up, so they need to get rid of it somehow. Nitrogen and oxygen they can just vent. Generally methane is flared to prevent…
