I believe it's the percentage of the total city population that are both 25-34 and have a degree. Not the percentage of 25-34 year-olds with a degree.


It might be easier to fire the lasers from the moon, but getting the lasers to the moon would be a huge pain.


Not to mention supplying these hypothetical moon lasers with enough power to blast these mini-probes into another star system.



I'm a bit surprised at the downvotes. I'm no scientist, but I meant this suggestion in earnest. As far as my layman's knowledge goes, I've always understood the Moon's He-3 reserves to be a "vast, as-yet-untapped power resource".


People have to learn how to harvest power from fusion before.


You know how they have chemically pumped lasers?

So it would be awesome to directly pump the laser from H3 fusion.

H3 fusion is actually very easy - I think we could do it today. We just don't have a readily available source of H3 for fuel.


3He fusion is easy—you can do it in a garage with some hacked-together equipment.

However, 3He fusion with net power output is exceptionally hard, even with complete disregard to cost. Much harder than deuterium-tritium fusion. We don't know how to do it yet.


Thanks for the correction. Seems the rosy predictions I remembered are not accurate.


Yeah, but then we'd be on the Moon. Again.


What happened to this line from the second file in the screenshot?

  -        var optionsGlassPane = new WebInspector.GlassPane(document);

An important part of viewing diffs for me is seeing what the old code was.


I'm just generally not a big fan of "X is some percent slower than Y" stats, because I find them counterintuitive. However, in this case I think something is wrong.

Rendering:

  jsblocks: 700ms
  React:    950ms (35% slower)
  Angular: 2200ms (310% slower)

Doing some maths:

  700ms + (700ms * 0.35) = 945ms
  700ms + (700ms * 3.10) = 2870ms
Looks like they got a little carried away when calculating Angular's rendering speed. Same thing with the "Syncing Changes" stats.

Edit: formatting


You are absolutely correct. It actually is an error. Thanks I will fix it.


Also, please add 'track by $index' to the Angular example.. might be a suprise for you.

(Makes Angular outperform both frameworks)


Are you sure you are getting correct results. Theoretically Angular can't be faster than both libraries because it does not implement diffing algorithm.


You can try yourself, the samples are there.

And it does, just not Virtual DOM
