Find the Discord channel in which you would like to send commits and other updates
-
In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

To remove a submodule you need to:
- Delete the relevant section from the .gitmodules file.
- Stage the .gitmodules changes git add .gitmodules
- Delete the relevant section from .git/config.
- Run git rm --cached path_to_submodule (no trailing slash).
- Run rm -rf .git/modules/path_to_submodule (no trailing slash).
- Commit git commit -m "Removed submodule "
- Delete the now untracked submodule files rm -rf path_to_submodule

On Tue Oct 27, 2015, history.state.gov began buckling under load, intermittently issuing 500 errors. Nginx's error log was sprinkled with the following errors:
2015/10/27 21:48:36 [crit] 2475#0: accept4() failed (24: Too many open files)
2015/10/27 21:48:36 [alert] 2475#0: *7163915 socket() failed (24: Too many open files) while connecting to upstream...
An article at http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/ provided directions that mostly worked. Below are the steps we followed. The steps that diverged from the article's directions are marked with an *.
- * Instead of using
su
to runulimit
on the nginx account, useps aux | grep nginx
to locate nginx's process IDs. Then query each process's file handle limits usingcat /proc/pid/limits
(wherepid
is the process id retrieved fromps
). (Note:sudo
may be necessary on your system for thecat
command here, depending on your system.) - Added
fs.file-max = 70000
to /etc/sysctl.conf
