Rsync over SSH - (40MB/s over 1GB NICs)

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

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

  • Separate big codebases into multiple repositories.

How to export and rehost your Tumblr site

How to export and rehost your Tumblr site

(Update: Version 3.2.0 of Jekyll looks like it's breaking a few things, so I've changed the guide to make you specifically install the version I was using, 3.1.3. I believe this is the issue: jekyll/jekyll#5145.)

You will be using jekyll-import to export your Tumblr site, Jekyll to (re)create it, and Surge to rehost it.

Update: You can also use Tumblr's native export feature in your blogs' individual settings. But rehosting that might be tricky. Read my comments below this post for how that works.

Setup and installation
