Unlocking the Secrets of Rails Secrets and Credentials

---

If you are like many (most?) of us, you have encountered Rails Credentials/Secrets and secret_key_base and may have been left a bit (or more) confused.

This post is an attempt to remove some of that confusion by

# When you need to process a hash with keys in sorted order
# you may have found the `sort()` function - but it only
# operates on an Array.
#
# Most of the time what is wanted is simply achieved
# by taking the keys of a hash and sorting those and
# then iterating over the keys.
#
# When, however the wanted result is a new Hash
# with all keys sorted recursively then this becomes

If your redis initial replication fails with error like 
"5101:M 20 Feb 18:14:29.130 # Client id=4500196 addr=71.459.815.760:43872 fd=533 name= age=127 idle=127 flags=S db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=13997 oll=1227 omem=192281275 events=rw cmd=psync scheduled to be closed ASAP for overcoming of output buffer limits.

this means that slave buffer is not enough and you should increase it (at master!) with command like
redis-cli config set client-output-buffer-limit "slave 836870912 836870912 0"

Automatically Prepend a Jira Issue ID to Git Commit Messages

Use a git hook to match a Jira issue ID from the current branch, and prepend it to every commit message

Assuming the current branch contains a Jira issue ID, you can use a git hook script to prepend it to every commit message.

1. Create an empty commit-msg git hook file, and make it executable. From your project's root directory:

    install -b -m 755 /dev/null .git/hooks/commit-msg
   

2. Save the following script to the newly-created .git/hooks/commit-msg file:
