The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare git@github.com:usi-systems/easytrace.git

TinyMCE with file manager

This post shows how to use TinyMCE 4.1 WYSIWYG text editor in a Rails 4 application for editing content in a textarea field.

TinyMCE is a powerful online WYSIWYG editor with many plugins.

If you want to insert an image by selecting it from images stored on server or upload an image to server, then you need to have a file manager with tinyMCE. TinyMCE comes with a file manager which is not free.

elFinder is an open-source file manager which can be easily integrated with tinyMCE 4.1.

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
