How to use this script:

1. Accept the quest under User Settings -> Gift Inventory

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

1. Replace mysql2 gem with pg in Gemfile.
2. Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.

b) after partifioning we must build the filesystems on the devices (format partitions) using mkfs

   
 mkfs.vfat -F 32 /dev/sdX1 // format efi-boot partition as FAT 32 

• system.cpu.idle: % Idle CPU
• system.cpu.system: % System CPU
• system.cpu.user: % User CPU

Sampling is somewhat complicated issue.

Firstly data is being emitted over a serial port at an arbitrary amount per second.

This data needs to be read from the serial port.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
