I don’t have a problem. I can quit any time I like. I only swipe recreationally. Every five minutes. Maybe I’m in denial. First stage, right?

update: Auto-correct and I are in a toxic relationship. Swiping just enables it. Tried quitting once. Worst 5 minutes of my life.

update: There’s this 12-step program… Step one was turning off predictive text. Didn’t make it to step two.

  • When I asked this question, I found out about raindrop.io. BTW, in that discussion you’ll find all the people with 500 tabs open. In this new one, you’ll also find lots of people who just close tabs regularly.

    Anyway, randrop is a service where you can dump links and go through them when you feel like it. The idea is, that if you know you won’t be checking a specific tab today, you can just save it in raindrop and cost the tab. I don’t like to have lots of tabs open anyway, but there are some sites I like to save for later. Stuff like vacation planning can produce twenty tabs just like that, and I’ll just throw them all into raindrop.

    Most of them are sorted into logical categories, and I’ll go through them when I remember to. For example, vacation planning will be useful later. When that time comes, I’ll start opening all those links I’ve accumulated over the months.















  • Vienna isn’t even the worst place for solar power. Consider places like Ireland, Scotland or Sweden for example. No wonder why wind, hydro or even tidal power suddenly begins to make a lot more sense. IMO, solar really begins to make sense in Spain, Italy, Greece and Turkey. Those places actually get some decent sunshine. Using solar power in Austria should be ok, but it’s not great by any means.

    Nearby mountains probably get in the way of building large solar facilities. Maybe you could combine solar power with farming. The panels can provide some shade to more sensitive plants.
    See also: Solar Atlas
    Sidenote: Iceland and the northern half of Norway, Sweden and Finland aren’t even on the map. I guess Solar Atlas is trying to tell you that you don’t need a fancy map to know that building solar in places like that is a waste of money.



  • Oh ok. So when the peak of the emission spectrum is in the IR range, the visible color will definitely be closer to red or orange. The amount of blue light emitted in that case will be very low. That’s what the thermometer experiment can definitely demonstrate clearly.

    However, if the black body is hot enough that the peak is in the blue wavelength band, then the total IR output should also be pretty high, just like everything else is at that point. I wonder if it’s even higher than in the first example. Would need to calculate that properly… Anyway there will also be a fair bit of UV, so don’t try this at home. Maybe even some x-rays if the arc is hot enough.

    As far as traditional carbon-arc lamps are concerned, people at the time wrote that the light was white. Maybe the arc was not hot enough or be perceived as blue. Also, the human eye is not particularly sensitive at those wavelengths, so that could explain some of it too.
