==Time Machine Backups==
===Prepare external Hard Disk===
Formating problem
Erase process has failed, press done to continue. Mediakit reports not enough space on device for requested operation.
Quoting [https://www.reddit.com/r/applehelp/comments/40yvjh/disk_utility_fails_to_eraseformat_an_external_hdd/] :
Here's what I would try. First run
diskutil list
to get the name to the disk you're trying to format. The below commands assume this is "disk1", but replace "disk1" with the correct disk if it's something different.
Now unmount the disk:
diskutil unmountDisk force disk1
and then write zeros to the boot sector:
sudo dd if=/dev/zero of=/dev/disk1 bs=1024 count=1024
finally attempt to partition it again:
diskutil partitionDisk disk1 GPT JHFS+ "My External HD" 0g

===Encryption Takes For Ever===
Quoting [https://discussions.apple.com/thread/7813232]: To speed up the process of TM encryption, go to Disk Utility, select your external HDD and erase and use the option journaled/encrypted. Once your external HDD is erased, you can redo the backup and the encryption will be as fast as a flash.

===Delete old backups===
mount backup drive in filder via connect to server
afp://my_DS_Hostname
now it can be found under Locations and you can delete old backups by sending them to bin (and cleaning that one afterwards)

==Install Google Keep Notes as Application via Chromium==
First download [https://download-chromium.appspot.com/?platform=Mac&type=snapshots Chromium] and move to applications than follow this [http://www.rawinfopages.com/mac/content/how-run-google-keep-window-desktop-mac-app guide] to create a shell script for automator.
Type = Application
Action = Run Shell Script
Contents = /Applications/Chromium.app/Contents/MacOS/Chromium --app=https://keep.google.com
Save as .app in Application folder and drag to dock, done!

==Settings==
Hide top panel from secondary screen from [http://osxdaily.com/2013/10/27/hide-menu-bar-external-display-mac-os-x/]
Mission Control -> Uncheck the box next to 2Displays have separate Spaces"

==Tools==
===Git===
Git requires apple xcode tools
xcode-select --install

===HomeBrew Package Manager===
from [https://docs.brew.sh/FAQ]
First update the formulae and Homebrew itself:
brew update
install
brew install mypackage
list installed pakages
brew list
uninstall
brew remove mypackage
You can now find out what is outdated with:
brew outdated
Upgrade everything with:
brew upgrade
By default, Homebrew does not uninstall old versions of a formula, so over time you will accumulate old versions. To remove them, simply use:
brew cleanup mypackage
or clean up everything at once:
brew cleanup
or to see what would be cleaned up:
brew cleanup -n

====Special Commands====
show dependancies
brew deps gnuplot
search for a package/version
brew search gnuplot
manual download file into cache to install a local file [http://mygeekdaddy.net/2014/12/05/how-to-install-a-local-file-in-homebrew/]
ignore dependencies
brew install gnuplot --ignore-dependencies

===Eraze Disk/fill by Zeros===
diskutil zeroDisk /Volumes/myDiskName/
alternative: create a big file
dd if=/dev/zero of=tmp_file.txt

===Spelling: unlearn a word/edit custom words===
vim ~/Library/Spelling/LocalDictionary

==Apps==
* https://rectangleapp.com Window mover (Control+Command+Arrows)
* https://maccy.app clipboard manager (Command+Shift+C)
