# 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.

Feedback

I'm sure I've gotten multiple things wrong here. Either flat out wrong, anti-patterns or just sub-optimal. I'm new to prometheus, grafana and mtail...so please feel free to share corrections/suggestions.

Background

There are a handful of custom nginx stats exporters.

Some are tying into internal nginx stats like the official nginx exporter: nginx-prometheus-exporter

"""Demo of logging in a multi-processing context.

Based on the Python "Logging Cookbook":
  https://docs.python.org/3/howto/logging-cookbook.html#logging-to-a-single-file-from-multiple-processes

Note on `QueueListener`:

  The main difference between the Cookbook example and this demo is that I use
  the `QueueListener` convenience class, whereas they write a bespoke
  `listener_process` function which does more or less the same thing as

Normally to create a virtual environment, we can do so from the command prompt with::

    C:\Users\me>python -m venv venv

This doesn't work when we are within a virtual environment though::

Signing VirtualBox Kernel Modules

These are the steps I followed enable VirtualBox on my laptop without disabling UEFI Secure Boot. They're nearly identical to the process described on [Øyvind Stegard's blog][blog], save for a few key details. The images here are borrowed from the [Systemtap UEFI Secure Boot Wiki][systemtap].

1. Install the VirtualBox package (this might be different for your platform).

What's Cool

• Encrypted root partition
  • AES-256 bit cipher
  • Argon2id variant for PBKDF
  • Sha3-512 bit hash
• rEFInd bootloader
  • With dreary theme
  • Optimal Settings (optimized for aesthetics, and boot time)
• Boot into backups thanks to refind-btrfs
