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 of any kind will not be tolerated. This is an LGBTQ+-friendly community -- if that is a problem for you, you should leave.
    • 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, no politics, no trolling or ragebaiting.
  • Don't come looking for advice, this is not the right community.
    • 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.
    • 6. (NEW!) Regarding public figuresWe all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
  • Keep discussions polite and free of disparagement.
  • We are never in possession of all of the facts. Defamatory comments will not be tolerated.
  • Discussions that get too heated will be locked and offending comments removed.
    • 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.

    funny thing - the SDRAM used provides 300kb/sec, while the SDcard used as storage provides 200kb/sec. Performancewise they could just skip most of the ram outside of booting and use the SDcard without losing much performance, especially since the SDRAM needs to be refreshed every 62ms for a duration of 3ms regardless of use.

    Edit: I LOVE this part:

    It takes about 2 hours to boot to bash prompt ("init=/bin/bash" kernel command line). Then 4 more hours to boot up the entire Ubuntu ("exec init" and then login). Starting X takes a lot longer. The effective emulated CPU speed is about 6.5KHz, which is on par with what you'd expect emulating a 32-bit CPU & MMU on a measly 8-bit micro. Curiously enough, once booted, the system is somewhat usable. You can type a command and get a reply within a minute. That is to say that you can, in fact, use it. I used it to day to format an SD card, for example. This is definitely not the fastest, but I think it may be the cheapest, slowest, simplest to hand assemble, lowest part count, and lowest-end Linux PC. The board is hand-soldered using wires, there is not even a requirement for a printed circuit board.

    6 hours to get into X is ridiculous- and i misread - it takes 6 hours to boot , and then hours more to get an X server running lol
