  • I wrote for Ars for a brief period, on Linux topics. This was prior to the digg exodus. As a writer, I got a set rate for each page of content, with an expected average word count per page. I’d get a bonus anytime my story hit the front page of digg, slashdot, or similar aggregater. It happened a few times.

    But that bonus incentive meant I was encouraged to specifically write stories that would resonate with those audiences. It wasn’t fraud or a scam – it was free market economic pressure. But the effect was the same – I was tailoring my content to maximize aggregator exposure.

    I began to submit my own stories to Slashdot and similar, because a minute of my time could pay me $100 or whatever.

    I am not sure that reddit is biased towards these publications as much as they are likely intentionally gaming the algorithms, and encouraging their writers to do the same – write content you know will hit the frontpage. I don’t think it is wrong necessarily, but it certainly isn’t organic.

    That said, Ars generally has very high quality content due to some very good reporters. Eric Berger comes to mind. So it could be both effects: quality and gaming the system.


  • Things like platinum notwithstanding, It will almost always be more expensive to go get things in space than on earth.

    Hell, even on earth it is often too expensive to get metals like iron if there isn’t rail or a port nearby. Imagine having to fly iron ingots around and the associated aviation fuel cost. Whatever crazy fuel bill you’re imagining, multiply by a hundred or more if you’re imagining getting it from space.

    No, all of those metals in space are best used to build some future version of our civilization _in situ. _



  • That alternative material is aluminum. It’s like a top four abundance material in the crust. It’s just super fucking hard to refine from minerals that don’t like to give it up without oodles of energy. Like, turn minerals into plasma levels of energy. So the irony is, to grow our energy economy past the need for copper, we will first need to grow our energy economy.

    Should fusion ever actually meet its promise, then this is one of the likely things we could do with this level of energy.

    If we ever become a spacefaring civilization, it’ll almost certainly be necessary during the colonization of other planets/moons/asteroids, since the geological processes that concentrate copper on the earth are not present in those places. Whereas aluminum is plentiful any place rocky.












  • I was about to date myself and say “there’s probably a dcop interface exposed”… But there’s probably a dbus interface exposed. You could write a script and plug it into a cron job or similar to tell it to adjust the background every hour or so. There are some nice dbus exploration tools available so you can discover the correct call to make.

    If that doesn’t work, the hue is probably stored in a human readable file somewhere in your .config folder. You could probably have a script adjust the value in the file directly. Might take plasma a little while to notice, but it likely will.
