    The short version is that life needs something that’s at least a little unstable in order to extract chemical energy from things.

    The post is correct when viewed in a particular light, on a technicality, if you squint. By that same technicality iron rusting is also burning very slowly. They’re ignoring the rapidity which is implied by “burning”. But yes, oxygen is unstable, oxygen helps burn things, and oxygen is toxic if you get too much at once. Though you’d need to be breathing pure oxygen pressurized to about 1.4 atmospheres, or regular air pressurized to about 7 atmospheres, for that last one to happen. It’s a legitimate concern for deep SCUBA divers.

    But why does life need instability? Chemical instability is, in basic terms, just stored chemical energy, and that energy wants to be released. The more reactive something is the easier it is to get energy from reactions involving it. There’s a balancing act here where more reactive means easier energy, but also more dangerous. Oxygen is in a kind of sweet spot where it’s stable enough that it’s not generally going to explode or catch fire on its own, but can be coaxed into doing those things in controlled ways with other chemicals to extract energy when needed.



  • Millennial with the opposite experience here. Once upon a time I’d use the phone all the time, could spend hours wandering the house and talking with friends, and calling anyone for any purpose was never a problem.

    Then I got a job answering phones for Comcast, was there less than a year before I quit. It’s been about two decades since then but it installed a hatred of phones in me that has lasted to this day.







  • I have a hobby development project with a modest community and maintain a Discord server basically because it’s necessary in order to avoid reducing my potential community reach by at least 50%.

    I’m active on GitHub and respond to comments and issues there. I maintain an official thread for my project on the official forum for the game it’s related to. I also keep all documentation, downloads, and guides off Discord and on the clearnet. Discord is still easily 80% or more of where people look for information about the project.




  • It’s an extremely bizarre suggestion given your request. I do want to defend the game (though not the suggestion) a little though.

    It initially presents as you say, but offers you opportunities to fight back in your capacity as border control. Letting in the right people can help the resistance and incite a coup, or enable you and your families escape from the country. It isn’t just Be A Good Tankie Simulator 2013, though you can play it that way too.



  • Yes, if you consider just a human-mass equivalent portion of the Sun then it’s not doing much, but that’s not really a useful comparison. We’re talking about total net entropy here, not entropy per unit mass.

    But yes, if it makes you feel any better, I’ll concede that if you had octillions of people our total metabolic energy output would, in fact, be significantly higher than that of the Sun.

    I dislike Microsoft and basically everything they’ve done with Windows post-7. Every machine I own that isn’t expressly for gaming is running Linux, and one of the two that are for gaming is also running Linux. When I build a new gaming tower to replace my current Windows one it will also run Linux, I just can’t be bothered to switch OSes mid-way.

    And yet people using childish denigrating nicknames like this immediately makes me disinclined to engage with the conversation. I don’t understand how anyone expects to be taken seriously while throwing around schoolyard-grade name-calling like this.


  • For those of you who’ve never experienced the joy of PowerBuilder, this could often happen in their IDE due to debug mode actually altering the state of some variables.

    More specifically, if you watched a variable or property then it would be initialised to a default value by the debugger if it didn’t already exist, so any errors that were happening due to null values/references would just magically stop.

    Another fun one that made debugging difficult, “local” scoping is shared between multiple instances of the same event. So if you had, say, a mouse move event that fired ten times as the cursor transited a row and in that event you set something like integer li_current_x = xpos the most recent assignment would quash the value of li_current_x in every instance of that event that was currently executing.

    I hate drive-thrus even as a driver. The intercom is always garbage, the menu is always presented in some insane arrangement that’s makes it basically impossible to peruse, paying at the window is awkward, receiving your food through the window is awkward, checking to make sure your order is correct is awkward, and to top it all off it usually takes longer than just parking and walking inside.

    It is baffling to me that anyone ever willingly uses a drive-thru.
