Graphics in Org mode using ditaa and TikZ

Org mode is well known for its powerful taking notes and task management capabilities, but for me it is always (or at least now) the document preparation mechanism that truly attracts me. Just imagine how amazing that we can just write content in org mode and then convert it to either PDF through LaTeX or HTML. Actually since Org mode is so good at these LaTeX tasks, I am even using the Org Beamer rather than the original LaTeX Beamer to prepare presentations.

PATH and Environments for Shell (bash) and Emacs

What is the difference between shell, bash, terminal? Shell is a command-line interpreter and there are various types of shell like Bourne shell (sh) and C shell (csh). Bash (Bourne-Again shell) is written as part of GNU Project to provide a superset of Bourne Shell functionality. Terminal used to be a physical hardware device to access a computer system when computer is bulky and expensive. The Terminal app on Mac OS X is called a terminal emulator actually, whose function is to emulate a terminal as its name suggested.

Set up a blog with Pelican and Org mode on Amazon S3

There are different methods to construct a website, for example you can develop quite complex webs on a web server. I attempt to learn Django before but dump it quite soon after some hours reading of the documentation. The reason is simple - I feel its capability is much beyond my requirement for a simple blog and I seriously concern the time I would spend on learning it. Later I learned another term called static website generator.
