Set a Reminder for yourself via the notification system
This will be seen through your system's visual notification system, notify-osd, notification-daemon, etc. --- sleep accepts s,m,h,d and floats (date; sleep .25m; date) --- notify-send (-t is in milliseconds && -u low / normal / critical) man notify-send for more information --- notification-daemon can use b/i/u/a HTML

display typedefs, structs, unions and functions provided by a header file
will display typedefs, structs, unions and functions declared in 'stdio.h'(checkout _IO_FILE structure). It will be helpful if we want to know what a particular header file will offer to us. Command 'cpp' is GNU's C Preprocessor.

Open the current project on Github by typing gh
Written for Mac OSX. When you are working in a project and want to open it on, just type "gh" and your default browser will open with the repo you are in. Works for submodules, and repo's that you don't own. You'll need to copy / paste this command into a file, then create an alias in your bash or zsh profile to the script. Detailed instructions here if you still need help:

SSH tunneling self-connection
- port 8080 on localhost will be a SOCKSv5 proxy - at localhost:localport1 you will be connected to the external source server1:remoteport1 and at bind_address2:localport2 to server2:remoteport2 - you will be using only IPv4 and arcfour/blowfish-cbc, in order to speed up the tunnel - if you lose the connection, autossh will resume it at soon as possible - the tunnel is here a background process, wiithout any terminal window open

make directory tree

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)
This creates an archive that does the following: rsync:: (Everyone seems to like -z, but it is much slower for me) -a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files. -H: preserves hard-links -A: preserves ACLs -X: preserves extended attributes -x: don't cross file-system boundaries -v: increase verbosity --numeric-ds: don't map uid/gid values by user/group name --delete: delete extraneous files from dest dirs (differential clean-up during sync) --progress: show progress during transfer ssh:: -T: turn off pseudo-tty to decrease cpu load on destination. -c arcfour: use the weakest but fastest SSH encryption. Must specify "Ciphers arcfour" in sshd_config on destination. -o Compression=no: Turn off SSH compression. -x: turn off X forwarding if it is on by default. Flip: rsync -aHAXxv --numeric-ids --delete --progress -e "ssh -T -c arcfour -o Compression=no -x" [source_dir] [dest_host:/dest_dir]
