Python snippets to do number representation conversion among binary/decimal/hexadecimal.

This posts explain how the emacs in-built query-replace-regexp command can be used to convert upper-cased strings to lower case.

I have a couple of theme packages installed on my emacs but I would like to assign a default theme.

I set the zenburn theme via a function zenburn. I set the leuven theme via another function leuven. But in my emacs startup I didn’t want to hard-code either of these function and thus arose the need to set a variable to one of these functions.

Some times I would need to define an alias in tcsh which can have optional arguments. tcsh doesn’t seem to support that directly.

Here’s how I solve that problem.

Update (2017/02/23) — Now I use GNU Global with Universal Ctags as back-end to generate the tag files. In emacs, I use the ggtags package – [config].

This post still has value if you are interesting in configuring ctags only.

This posts shows how to set up ctags to parse SystemVerilog code and how to access that tag database in emacs.

I found how to escape a $ sign in a regex expression in a tcsh alias. BUT it is UGLY!

Update (2017/02/23) — Now I use Hugo instead of Octopress for blogging. But the same method of using [^1] works for creating footnotes.

While looking for a way to add footnotes to my posts, I came across this post.

Based on that, here is how I got the footnotes working:

Faster way to send the same command to each and every pane in your tmux session.

If you have bc installed, you can use it to do math operations on variables in a Makefile.

This post shows how to get the current directory name without the preceeding path, using awk or rev+cut or the boring basename.
