This is a slightly stripped down version from our internal bug tracker. The point of posting this publicly is part FYI, part peer review. I'm hoping someone can look at this, disagree, and tell me all the downsides of using the C
locale or point out things I've misunderstood. The Recommendations
section in particular is contextualized by our database serving a SaaS product for users from many different locales, thus making locale a render level concern. YMMV, caveat emptor, etc.
Collation defines the character ordering for textual data. For Postgres, https://www.postgresql.org/docs/current/static/locale.html:
The locale settings influence the following SQL features:
- Sort order in queries using ORDER BY or the standard comparison operators on textual data
- The
upper
,lower
, andinitcap
functions
These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.
Most of this is scrambled from the following pages:
$ ssh remote-host "epmd -names"
epmd: up and running on port 4369 with data:
name some_node at port 58769
Note the running on port
for epmd
itself and the port of the node you're interested in debugging. Reconnect to the remote host with these ports forwarded:
$ ssh -L 4369:localhost:4369 -L 58769:localhost:58769 remote-host
