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 making money while developing the technology to do, and then us

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) encourages you to consider what ways to handle

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 to reach X but also have fuel left over. However to get 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 either a secondary explosion or something coming up the transport

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 tower.

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 good, but then one engine on the booster went out. - Relight

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 to make the final connections. However, I do understand wh

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, and payload mass is the most important constraining factor.

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 amount is 0. The practicalities of their illegality then co

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 aphantasia test with an apple, I can hold it's 3d

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 certainly isn't present in China. Those are the unimpo

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, but has found other paying customers. The moon has t

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 op example, the block is evaluated twice, once for e

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 to get the machine to do what I want it to do. So, eg, h

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 enforcing systems are very frustrating to hit. They usua

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 squared. It's common to specify a length

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 the outer answer, and had to work backward 3-4 lay

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 depend on that step. This reduces the steps to build to

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 nuclear destruction. Along with various proxy wars, techno

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 explosive gas buildup and (the worst of) greenhouse gas

Well, Starship is specifically designed to make it to Mars if refueled in LEO. So it could deliver monstrously large Mars rovers. If they're going for the outer planets, they could do as you suggest after the first burn using a refue

Zig is even better: 1. u8 and i8 are 8 bits. 2. u16 and i16 are 16 bits. 3. u32 and i32 are 32 bits. 4. u64 and i64 are 64 bits. 5. Arithmetic is an explicit choice. '+' overflowing is illegal behavior (will crash in debug and rel

Wasm makes no distinction between signed and unsigned integers as variables, only calling them integers. The relevant operations are split between signed and unsigned. https://webassembly.github.io/spec/core/appen
