Installing Fedora on Macbook Pro retina

1. Download Fedora 26 iso, create a usb bootable media
2. Use diskutil list to figure out which drive is the usb, on macbook pro with 1 hardrive, the usb is /dev/disk2
3. Umount the disk using diskutil unmountDisk /dev/disk2 or use Mac's Disk Utility (just umount, don't eject, umount removes it from directory structure and eject disconncet it altogether)
4. Use dd(a low level cp) to write iso content into the usb drive, sudo dd if=~/Downloads/Fedora-Live-Desktop-x86_64-20-1.iso of=/dev/rdisk2 bs=8m, this will take a bit of time, make sure you wait until it's done, additionally compare the size or checksum to make sure all has been copied (not that necessary since if it weren't copied, it'll err at boot time)
5. Use Disk Utility to shrink Mac's harddrive to create partition for the subsequent fedora installation
6. Boot to recovery mode (cmd+r) and disable SIP (termina

Vim Cheat Sheet

Vim is an advanced CLI based text editor. Many key combinations used in Vim are easily associated with a memorable phrase. One effective way to use Vim is to associate phrases with Operators, Text Objects and Motions. Then compose a phrase for what you want to do. Start with an Operator followed by a Text Object or Motion. Prefix an Operator, Command or Motion with a number/count to extend it.

Table of Contents

• Modes
• Operators
• Motions
  • Left-Right Line Motions
  • Up-Down Motions
• Word Motions
