  • My experience is that the programmers from the first row very much still exist. My theory is that the number of programmers from the first row stayed the about same or even increased slightly. There are so many more so called “programmers” overall now, however, that in relation the first row programmers are much rarer now. And to be fair, you don’t need a programmer capable of programming entire games in assembly to center a div.


  • It’s all based on a very fundamental mathematical law: if you increase the size of something, the volume increases with the third power while the surface area increases with the second power. An insect twice as large would be 8x as heavy and need 8x as much oxygen but 4x as much surface area.

    That’s also the reason why insects are as strong as they are. The strength of a muscle scales primarily with the cross section area of it, which again scales with the second power. So if you’d increase the weight of an ant by a factor 10,000,000 (e.g. 5mg to 50kg), the expected strength would increase by 10,000,000^(2/3) ≈ 46,400. If it could lift 10x it’s weight at the original size, it could now only lift about 4.6% of it’s weight

    Ladies and gentlemen of this supposed jury, is it really fair to say my client hit him, when the brick is essentially 100% empty space? And isn’t he also essentially 100% empty space so can he even be hit?

    But, ladies and gentlemen of this supposed jury, I have one final thing I want you to consider. Ladies and gentlemen, this is Chewbacca. Chewbacca is a wookie from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about that; that does not make sense! Why would a wookie, an 8 foot tall wookie, want to live on Endor, with a bunch of two foot tall ewoks? That does not make sense!

    But more importantly, you have to ask yourself, ‘what does that have to do with this case?’ Nothing. Ladies and Gentlemen, it has nothing to do with this case. It does not make sense! Look at me. I’m a lawyer defending a major record company, and I’m talkin’ about Chewbacca! Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you’re in that jury room deliberatin’ and conjugatin’ the Emancipation Proclamation, does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.








  • The point of my comment is that if trees wouldn’t exist, they would seem like some futuristic sci-fi solution too good to be true. Just because something is shiny new tech, it isn’t automatically better. Sure, just planting trees won’t save us if we release all the carbon that is already captured in the form of fossil fuels, but how about we stop releasing all the carbon that is already captured in the form of fossil fuels?


  • I’ve heard there’s a practical green solution to carbon capture. The units are practically maintenance free and power themselves with solar energy. This allows to deploy them on many small patches of land. The captured carbon is stored in solid organic compounds that may be used as building materials. It may sound to sci-fi to be true, but it’s actually just trees.





  • That’s the beauty about open source: it isn’t beholden to the whims of anyone. If disagree with the Linux Foundation, you’re free to make your own independent fork. Others that agree with you can then start contributing to the fork. And this isn’t a purely theoretical scenario as it has happend with other open source projects before.

    To escape a body of mass you need to have enogh velocity (kinetic energy) to overcome the gravitational pull of that body. You can imagine it like a ball sitting in a bowl. With little velocity it will just roll back and forth but if it’s fast enough it can roll out of the bowl and escape it’s influence.

    That critical speed is called “escape velocity” and it depends on mass and distance from a body. The escape velocity of earth (from the surface) is about 11.2 km/s and the sun’s escape velocity (from earth orbit) is about 42.1 km/s. Earth orbits around the sun at about 29.8 km/s. If you launch in the direction of Earth’s orbit, you will orbit the sun already at about 41 km/s, so you “only” need 1.1 km/s more to escape the sun, too.

    If you tried to reach the sun, you could launch in the opposite direction leaving you orbiting the sun at about 18.6 km/s. Since there is almost nothing in space you won’t slow down from friction and the orbit won’t decay. Instead you’d have to accelerate opposite the direction you’re traveling. Now, calculating exactly how much you’d need to decelerate isn’t trivial since you don’t want a stable orbit but an elliptical orbit that just touches the sun at the closest point (perihel). I don’t know how much deceleration that takes, but it’s propable that it’s easier than accelerating by 1.1 km/s to escape the sun.
