Installing Gitea on Raspberry Pi with nginx, SSL and automatic backups

Setup Gitea on Raspberry Pi (3)

These instructions are based on this article: https://www.alexruf.net/2016/05/23/setup-gogs-git-service.html.

Setup Raspberry Pi with minimal Raspbian image. You need to connect to the HDMI port and set the following:

sudo raspi-config

There you need to enable the SSH server and you should change the hostname.

Optimizing postgresql table for more than 100K inserts per second

Optimizing postgresql table for more than 100K inserts per second

  • Create UNLOGGED table. This reduces the amount of data written to persistent storage by up to 2x.
  • Set WITH (autovacuum_enabled=false) on the table. This saves CPU time and IO bandwidth on useless vacuuming of the table (since we never DELETE or UPDATE the table).
  • Insert rows with COPY FROM STDIN. This is the fastest possible approach to insert rows into table.
  • Minimize the number of indexes in the table, since they slow down inserts. Usually an index on time timestamp with time zone is enough.
  • Add synchronous_commit = off to postgresql.conf.
  • Use table inheritance for fast removal of old data:

Automatic Git commit signing with GPG on OSX
# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.
# Add the following to your shell init to set up gpg-agent automatically for every shell
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
source ~/.gnupg/.gpg-agent-info
export GPG_AGENT_INFO

Welcome to #rubyonrails

Please behave in a polite, considerate and inclusive manner in the channel at all times. People volunteer their time in the channel to help people like you with your Rails problems and some respect (in both directions) will go an extremely long way.

These rules are in place so that you can get the quickest and best support from #rubyonrails.

Rule #0: Show rather than tell. Explaining your problem with code, stacktraces or errors is always preferred to explaining it with just text. Show us what's happening, rather than telling us.

  1. Do your research before hand. Your question may be answerable with a quick Google search or by simply experimenting. If you're using a method in Rails, look it up in the API Docs or in the Official Guides.
  2. If you've tried Googling, explain what terms you've tried to use so people can better help you.
