SISC Scheme on Android's Dalvik VM

I managed to invoke REPL on Android's Dalvik VM. I encountered a number a problems, but amazingly I managed to get the REPL to instantiate and manipulate a Java class that ships with the Android OS.

As far as I know, this is the first time that anyone has managed to get a Scheme implementation to run on Android

Read this tutorial if you want to find out how I did it.

XSL Stylesheet for GEDCOM 5.5 XML

I just released a XSL stylsheet that can be applied to a GEDCOM 5.5 XML document. It will produce an XSL-FO stylesheet that can in turn be converted by fop into a pdf document. The PDF resembles forms produced by ProGenealogist.com.

Using XSLT to Fix lyX's Docbook XML

lyX is currently my favorite text editor, especially when it comes to writing software documentation. LyX's support for Docbook XML is slightly cludgy, though, because the application is really designed to help create LaTex documents. I have written a tutorial on how to use lyX to produce Docbook XML which can be transformed into XHTML or PDF documents. This tutorial shows how to leverage XML technologies, such as XSL, to create customized versions of Docbook XSL stylesheets that fix some of lyX's Docbook problems. The tutorial can be read here.
