> whatever you think of Musk Musk is a clown but I'll give him one thing: he cares about technology. That's something that very few modern CEO in big tech have and probably gives him the edge in making his project successful.
> Musk is a clown but I'll give him one thing: he cares about technology. His hot takes on software / software architecture have been disappointing[1], and made me question the validity of his assertions in domains I have no expertise in (rocketry, computer vision and manufacturing). 1. Also, he wants to remain in charge of "Servers and Software" at Twitter even after (if?) He steps down as CEO.

Re: How to start a rocket engine
#122I could watch stuff like this all day. Tim's stuff is so great. Easy to be jealous of, since being YouTuber seems easy, but to make quality content, it really can't be. And then he's going around the moon, it's really mind blowing to see the success he's had. His interviews with Musk are a treasure trove as well, whatever you think of Musk.
He, like most big Youtubers, probably have a large crew of people working with them. The article was written by Trevor Sesnic, the video was likely edited by others, I don't know if he did the graphics, but Tim still did a lot (and arguably did the most fun stuff). Smaller Youtubers need to do all of that, and from what I've heard editing is the absolute worst given how time consuming it is. Many Youtubers struggle w…
This totally depends. If you're an editor, there is a great sense of pride of turning the pile of content handed to you into something cohesive and compelling is quite a skill. Some people just don't like it, and that's fine. I don't like building UIs, but sometimes I just gotta do it. It makes me appreciate those that do the task I don't like that much more. walk a mile in another person's shoes so to speak.
Just like coding, you can get in the zone with an edit and things just start flowing. It usually comes after multiple sessions of sitting there scrubbing through the content thinking to yourself "wtf do I do with this?" when inspiration finally hits. You just start remembering a shot from this clip that flows nicely with this next clip and it suddenly "makes sense". It gets really spooky when you then try to find some audio clip like music and drop it in and it pretty much lines right up. That's for unscripted stuff that's just kind of produced like film is cheap kind of shooting.
When you have scripted stuff that every shot has been logged and tagged where there's variations on delivery or any other slight thing that makes it appear to be the same thing over and over again comes with its own challenges and rewards. Sometimes, there's a perfect delivery but something doesn't line up continuity wise, so it looks like it can't be used. Then, you scrub some other angle or reverse or cutaway and hide the edit so that you can use that perfect delivery or borrow that perfect reaction that otherwise might not have made sense.
There's a reason it's an art. Not liking it doesn't mean you're wrong for not liking it personally, but it doesn't make it the absolute worst.

#123I'm surprised at the amount of people who enjoy EDA. I find him very irritating. Most people at my small space company find him extremely irritating. He is not a rocket scientist. He parrots silly buzzwords like "biomimickry" like a fanboy, not an engineer. He suggests things to Elon for how to do rockets that are just pants-on-head dumb. His blind fanboyism and arrogance irritate so many people who work in space. I'…
I'm comparably bemused by the enthusiasm shown here towards some life sciences stuff. HN users are perhaps not the discerning polymaths you imagine.

> His interviews with Musk are a treasure trove as well, whatever you think of Musk. My main take away from those interviews is just how knowledgable Tim is, he's able to engage in low level and in depth conversations about how these engines work. It's not just superficial high level knowledge from making videos, he is thinking himself how to optimise and improve these things, and leading that conversation. The passi…
To be honest he's regurgitating a lot of information. He has large gaps in his knowledge but presents himself as extremely knowledgeable. Understanding a rocket engine as a layman is easier than understanding a diesel engine. EDA acts like he's a genius but he is not. I work in space. Some of my coworkers have met EDA. He is insufferable and extremely arrogant. A very difficult person to be around.
My only defense is that Ted Lasso Season III lands next week:
YOU WORK IN SPACE?!?
Man the commute must be terrible.

It’s pretty rough because those ‘you’re wrong’ videos are actually just as wrong as he was. The main issue is that these complicated topics are difficult to describe properly is a 20 min English video that has to be edited to be interesting. How electricity propagates is really complicated topic involving 3D vector calculus, for the EM waves. Most people don’t do electronic circuits by evaluating the vector field, th…
Can you link to a 100% correct explanation? Can be in any format.
So Feynman Lectures on Physics for example are hard to beat. Though you will want to check for the various errata, the fact it was taught by a world class expert and received a great deal of peer review after the fact is about as much as you can hope for on any subject.

The best you can get is stuff people have extensively peer reviewed. So Feynman Lectures on Physics for example are hard to beat.

Is the implication then a 100% correct explanation does not exist?
I suspect there’s multiple math textbooks which combined with their errata are error free, but I don’t know if that’s true.

HN is mostly software devs, as someone in the bio sciences whenever I see comments about my field they're nearly always wrong unless another person in the field is commenting which isn't very often. It seems like software devs like to think they understand things when it's just barely surface level knowledge, I don't know why
I'm always surprised how quickly a thread than isn't software related nose-dives. Me and my colleagues joke about the weekly HN thread of people misunderstanding some physics article, or posing a nonsensical solution to a "trivial issue within physics".

#129> [Ignition chemical TEA-TEB] is quite expensive, costing roughly the same as the cost of RP-1 for the Falcon 9. Is it true that the ignition chemical costs as much as the fuel? That sounds incredible.

Could you give me an example of his 'arrogance'? I've been watching his content for some time, and I'd say he's always been very upfront and transparent about being an enthusiast/fanboy and not an engineer. His concept is to be an audience insert and ask the stuff his non-professional audience would ask, as a sort of avatar. I would expect no more expertise from him than from myself. If the people he interviews are h…
I can't find the tweet where he suggests to Elon how to design the sides of the rocket. Elon just shuts it down. I've never once heard EDA push back on anything Elon says even though Elon can say some outlandish things every now and then. That blind fanboyism is annoying. While not public, my friend was his liaison at Blue origin when he toured. He was extremely rude to the team at Blue. It actually surprised the med…
