Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
    • 5. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
    • Β 

    Please report posts and comments that break these rules!

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

    Technically, if it's a land line port and still connected to an exchange that hasn't gone completely VoIP (that's a thing where I am), it might actually be possible to build a charger module that plugs into that port.

    Would it be worth it, though? ... No.

    Low power is supplied over old land-lines for the purposes of making telephones ring and powering other handset bits and pieces, within reason of course. Using it for anything else is undoubtedly illegal as phone lines aren't rated for huge power draws.

    (If you're interested, there are videos online where people have hooked up LED lamps etc.)

    But, let's say that module existed and was legal. Your niece still wouldn't be happy with it.

    To avoid burning out to the telephone line, any such device would have to be a r e a l l y s l o w trickle charge.

    I wouldn't even think about it for emergency power outages. A battery backup is a better option.
