How to change your voice live on Linux

Mar 16, 2019• • Time to read: 1 minute

You can change the pitch of your voice on a computer running a Linux-based operating system for free. It’s quite fun, if not useless.

If you don’t have a Linux OS, you can install one onto a thumb-drive and reboot your computer into it as a demo without touching your hard drive at all.

Life-changing keyboard shortcuts

Mar 3, 2019• • Time to read: 1 minute

Go into some text box anywhere on a computer and type some stuff and then press Ctrl-Backspace. It deletes the entire previous word! This is much faster than repeatedly pressing backspace or holding it down when making corrections.

Now try Ctrl + left/right arrow keys. This moves the cursor one whole word at a time in any direction. If you hold SHIFT while doing this, it will highlight the words. Once something is highlighted, you can just type a replacement, or you can change the size or font or anything. It’s really nice to do this on the keyboard without reaching for the mouse because keyboards are more expressive than mice, and faster.

Here’s a whole list of similar text-editing shortcuts:

Effect Windows/Linux macOS
Delete previous entire word Ctrl-Backspace Option-Delete
Delete next entire word Ctrl-Delete Function-Delete
Move cursor to previous or next word Ctrl-LEFT, Ctrl-RIGHT Option-LEFT, Option-RIGHT
Move cursor to beginning of line Home Ctrl-A
Move cursor to end of line End Ctrl-E
Move cursor to beginning of document Ctrl-Home Command-Up
Move cursor to end of document Ctrl-End Command-Down

Enjoy that new superpower!

Self-publishing a book with reStructuredText, Sphinx, Calibre, and vim

Feb 16, 2019• • Time to read: 11 minutes

I got inspired to write Digital Superpowers after realizing how straightforward it is to publish books these days. Anyone who can put together a manuscript can head on over to a direct publishing service and have it up and for sale. E-books are particularly straightforward to self-publish, but print-on-demand paperbacks are almost as easy. If you have dreams of getting a book out the door, now is a great time to do so.

Writing and promoting any book is the bulk of the work, but this post is about the toolset I chose to use in preparing my manuscript.

I wrote Digital Superpowers as a series of text files in reStructuredText. I used Sphinx to process these into the ePub format, then used Calibre for final touches, and finally KindleGen to convert the manuscript into the Amazon MOBI format for upload to the Kindle store.

Why reStructuredText?

I chose to use reStructuredText (RST) for a few reasons:
