Recent works & projects by Seth Kenlon.

Stuff You Can Read

Video Codecs and the Free World

A very popular article on video codecs for both printed and online edition of Linux Journal; it has been cited in a thesis paper, in technical documentation, and has resulted in me being invited to a number of guest speaking gigs at various technical conventions.

Lightworks articles

Articles about video editing on Lightworks, originally for the site but since that went away, they got moved to Slackermedia.

Ken Stone articles

Once-popular articles about that old boring version of a closed source video editing application. Of course, I use and recommend Linux editors instead, now.

Six Article series on video editing on Linux with Kdenlive (all of which were later compiled and published by as a free downloadable ebook). Monthly Column

A year after my 6-part articles for the site, I was invited back to write a monthly column for on multimedia.

Normalizing Audio on the Linux Command Line

Article for printed edition of Linux Format in the UK

Using Lightworks

Programming Book

Qtractor User Manual

More Linux Identity Articles Than You Can Shake a Fist At

Too many articles for Linux Identity magazine to conveniently list; perhaps most significantly, I wrote their Fedora Linux FAQ which has been run multiple times in a number of issues, and a "How to Modify PDFs" article which was, at least at the time of this writing, on their most-downloaded list.

Editor for

For a while, I was a copy editor for the official news site of the KDE desktop environment. I have written some articles for The Dot, but it being a news outlet, most articles are transitory.

Linux Audio Explained

I have seen trained professionals panic when their computer mysteriously isn't playing sound. I like to think that Linux users are more rational than that, so to ensure that people understand how audio on Linux works, I wrote this article.

Installation Guide for Dragora Linux

Documentation for the Argentinian distribution of Dragora Linux. My docs appear to be offline now.

Stuff Your Computer Can Use

Multimedia Sprints

I have organized two "multimedia sprints", in which me and some friends download as much useful free (Creative Commons, GPL, OFT, and similarly-licensed) content from the internet we can find in one afternoon, and compile them into useful "power packs" of raw materials to help artists make cool art. This is especially useful for people who either don't want to keep using the same pre-fab building blocks from commercial software packages, or people who don't purchase commercial software in the first place.

Version 1 contains 2,455 free fonts, 23 sample banks, 28 sets of digital scrapbook material, over 302 GIMP brushes, 45 sets of vector art, some icon sets, random wallpapers and geek art.

Version 2 contains 150 gigaSamples, 99 laboriously crafted Hydrogen Drumkits, 11 beautiful new free fonts, 100 tile-able patterns, 29 GIMP Brush sets, 50 GIMP enhancements (including anitools, GIMPressionist filters, gradients and color palettes, and more), plus six icon sets, random wallpapers, and geek art.


Patched the code and forked the project of Screenplay-mode, turning it into Screenwriter-mode; a cross-platform and free screenwriting plugin for the Gnu Emacs text editor.


I wrote and released an open source software suite (we liked to call it "Free Software" to denote that it is free for you to re-write, share, and heck even re-sell) to help with script breakdown, character reports, location reports, casting, scene numbering, and so on, called Screenplay-tools. It is considered a part of the Screenwriter-mode application even though it is actually a free-standing app with an entirely independent codebase.


A Free Software interface to the collection of install scripts. Modeled after BSD Port and Gentoo Emerge (but let's face it, everything eventually gets used like yum in the end)


A Free Software, automated mouse shaker for those times you just need a quick way to avert your screensaver.


A Free Software tool to generate Hydrogen drumkits from folders of sounds on your hard drive. Written in Python for maximum cross-platformedness.


A Free Software method for creating self-published books and ebooks using standardized, professional-quality templates. I created this in an attempt to make professional-grade publishing smooth and accessible to artists, but since its creation I have gotten so comfortable with many of the lower levels this seeks to abstract you from, that I actually do not use it much any more and just write in XML. But this still has a lot of value for people who do not know XML.

[Patched] Flowblade

Shortly after version 0.10.0 of the very fine Flowblade video editor was released, the GnomeVFS library was deprecated. Many Linux distributions continued to support it, but if you ran a distribution that did not, then Flowblade failed to launch because it required a Python hook into GnomeVFS in order to determine mimetypes of imported media.

To fix this problem, I devised a way to use builtin Python tools to perform mimetype detection, and sent the developer, Janne, a small patch. He rolled it into an updated version of 0.10.0 and now everyone benefits.

[Patched] Txt2Docbook

This is an utter, embarrassing hack but it's darned useful. Txt2Docbook is a Perl script written by Thomas Weber (some developer much smarter than me). It has not been maintained much lately, so I made some simple modifications and one very useful patch to make it actually work on modern systems. I did submit the patch to the project's code base but never heard back, so this is my modded version of a very very useful script. All credit goes to Thomas Weber, really.


A Free Software, cross-platform commandline trashcan to "fix" the rm command.

Some SlackBuilds

Free Software install scripts for applications ranging from multimedia tools, like HandBrake, JSampler, LiVES, Font Matrix, MuseScore, a collection of ICC Profiles, GIMP Paint Studio, and some geeky tools like Fluxbox docklets, ophcrack, airpwn, fram, a patched version of txt2docbook, and a few others.

Some Slax Modules

Modular software packages for a Slackware-based Live Linux distribution. Packages include Emacs, Pygame, and others.

Switch to Linux

A website helping computerists switch to Linux. It is heavily biased toward Fedora Linux, but all of the code and text is publishd under the GNU Free Documentation and GPL licenses, so it can be adapted to be more specific toward other distributions as well.

Trying Slax Linux

A website helping computerists who are using Slax Linux. It is directly aimed at students of either my programming classes or of my "Programming Book" textbook, but could be used by anyone trying out Slax. The sites covers the basics of the KDE desktop, the basic applications available, installing new applications, and common troubleshooting issues.

The OS in the Shell

A website helping geeks/comp sci students/techies understand how to use the UNIX shell as their primary operating environment. It takes a task-based approach to teaching the shell, rather than throwing a bunch of random commands at the reader with no context and expecting it to make sense.
