  • Signing PDFs
    If you mean signing as in "signing with your handwritten signature", you could use Okular () which easily allows you to do that. Filling out forms also works nicely. Source: over 2 years ago
  • Alexandria: A minimalistic cross-platform eBook reader
    I was in a similar position lately until I found Okular. Have you tried it? https://okular.kde.org/. - Source: Hacker News / almost 3 years ago
  • Help with PDF's
    I would try Okular first, though, which is free and open source: https://okular.kde.org/. Source: about 3 years ago
  • EPUB 3.3 becomes a W3C recommendation
    KDE's okular might be a good choice. I haven't personally used it for epub but I know it supports it. https://okular.kde.org/. - Source: Hacker News / about 3 years ago

  • Filament to use on High Altitude Balloon
    You can research some more in those two sites (especially in sciencedirect.com, you can filter by open studies if you are broke like me). Source: about 3 years ago
  • Tesla share down another 5%
    That's incorrect. You also need to get some better sources. EPA.gov, the ICCT report, and sciencedirect.com are highly political institutions. Source: about 3 years ago
  • Scientifically Documented Medical Miracle
    First of all, sciencedirect.com is not a peer reviewed science site. it gets a 2 out of 4 stars when rated by actual scientists. Source: over 3 years ago
  • What's your "hot take" or unpopular opinion when it comes to dating?
    The source "sciencedirect.com" is at the end of the quote and you can easily do your own research but you won't. Also the point is to show the hypocrisy that people accept random standards like that because you're programmed to. Source: almost 4 years ago
  • Solar Power for Coop Water Warmer
    You might want to look at building a passive solar water heater. According to sciencedirect.com, "passive solar water heating systems generally transfer heat by natural circulation as a result of buoyancy due to temperature difference between two regimes; hence they do not require pumps to operate. They are the most commonly used solar water heating systems for domestic application." They are non-electric. Source: almost 4 years ago
