I'm trying to register for the Archlinux forum, and they have a question at the bottom that verifies that you're using Linux:

What is the output of "date -u +%V$(uname)|sha256sum|sed 's/\W//g'"?(Required)

The answer I gave was:


I tried on Ubuntu and Arch and got the same result. No dice. Here are some of the pieces (that seem to be working):

$ date Wed Jun  5 15:16:05 UTC 2013

$ date -u +%V$(uname)

Is there something I'm doing wrong? If not, who should I contact about this?

    Well, someone actually involved with the arch Linux forum perhaps?

  • +1 Same result here. Are you sure they don't mean you to run this on an Arch Linux installation? And could you link to the relevant page?

  • Looks like somebody has asked "Are you capable of running a Linux forum?" ... Jun 5, 2013 at 15:32
  • @l0b0 updated question with link to the registration page. Also, I actually did try both Arch and Ubuntu just in case.

  • @terdon since I can't register for the forum, I don't think there's a way for me to make any noise over there (no "contact us")

1 Answer 1


Surely this will be resolved soon, but in case anyone else encounters this problem before it's resolved, the answer is:

  1. submit the form
  2. do not press the browser's back button
  3. re-paste the answer into the form
  4. re-submit the form

    Seems like functionality intended for people who hate it when people frequent their public web forums...

    It's actually functionality that prevents the otherwise overwhelming volume of spam that plagued us for several months, sucking up huge amounts of the time people who run the boards volunteer...

    there's probably a better way to mitigate spam than presenting the user with a seemingly broken form.
