You're right, both achievements are huge.

That said, I'm not too sure I understand the line "the kinetic energy transfer at a 100 km reference altitude is what matters"...

What is the "kinetic energy transfer at 100km" ? Why not say that what matters is the "kinetic energy transfer", period? It doesn't make any sense to me to put it the former way.

Cool video, thanks!

That seems pragmatic enough to me, and also quite effective. I live in France and, unless I'm wrong, the highest of the oil-related taxes here apply to the consumers, when you're getting gas at the gas station. Instead, your proposition - to apply a $10 tax on the barrel - would apply the same taxation on any fossil fuel usage, be it plastic fabrication, air transportation, electricity generation, etc... That makes a lot more sense environmentally-speaking.

Thinking about your post, I think you have a point there.

I noticed that in his speech, Elon Musk doesn't talk at all about what form the carbon tax should take.

In reality, if a carbon tax went into action, 90% of its effect would hit fossil fuel companies and nobody else.

Am I wrong? How do you implement a carbon tax then?

Can you give us some explanatations about your text? What's a FUD? and a nominal carbon tax?

Good point

Too bad for Paris that the program won't be taught there anymore

The stream is OK when viewing from Europe (or from France as far as i'm concerned).

I thought Linus had mostly worked on the inner workings of Git (the "plumbing"). These are awesome. But the CLI part is not straightforward at all. I keep seeing people new to Git having great pain to use it.

So, if some new folks come up and expose clearer CLI concepts than Git does, then I completely agree with their initiative. On top of that, if it remains compatible with existing Git repositories, then I will surely give it a try and maybe use it regularly.
