Load lib files in production (Rails 5)

If you have your code defined in classes in lib/ folder you may have problems to load that code in production.

Autoloading is disabled in the production environment by default because of thread safety.

Change config/application.rb:

    config.autoload_paths << Rails.root.join("lib")
 config.eager_load_paths &lt;&lt; Rails.root.join("lib")

# Sample Nginx config with sane caching settings for modern web development
#
# Motivation: 
# Modern web development often happens with developer tools open, e. g. the Chrome Dev Tools. 
# These tools automatically deactivate all sorts of caching for you, so you always have a fresh 
# and juicy version of your assets available.
# At some point, however, you want to show your work to testers, your boss or your client. 
# After you implemented and deployed their feedback, they reload the testing page – and report 
# the exact same issues as before! What happened? Of course, they did not have developer tools 
# open, and of course, they did not empty their caches before navigating to your site.

Первое, без чего я уже не могу работать — alfred. Кроме запуска программ я в нем ищу файлы/папки, т.к. finder тупой: Постоянно использую clipboard history:

В сниппетах у меня сохранены какие-то линуксовые команды, которые я никак не могу запомнить, смайлы (╯°□°）╯︵ ┻━┻ и ¯_(ツ)_/¯ (не запоминать же их)

Из плагинов постоянно использую:

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
