Building GD.pm and libgd

January 14, 2005 By Todd Harris Leave a Comment

Subject: Building libgd and GD.pm on Mac OS X.3
Prerequisites: Apple X11 installed

Look, about a billion people have asked me how to build gd and libgd and Mac OS X. It really isn’t that difficult\. Here is how to do it. Please note that there may be a newer version of libgd by this point.

# fetch and build libgd (current for 2.0.15)
% curl -O http://www.boutell.com/gd/http/gd-2.0.15.tar.gz
% gnutar -zxf gd-2.0.15.tar.gz
% cd gd-2.0.15/% ./configure CPPFLAGS=-I/usr/X11R6/include/freetype2 \
--with-freetype=/usr/X11R6/lib
% make
% sudo make install

# Fetch and build GD.pm
% curl -O http://stein.cshl.org/WWW/software/GD/GD.pm.tar.gz
% gnutar xzf GD.pm.tar.gz
% cd GD-*/
% perl Makefile.PL
% make
% make test
% sudo make install

Font sizing in CSS

December 16, 2004 By Todd Harris Leave a Comment

I found two interesting discussions today on how to handle font sizing in CSS.

The folks at the thenoodleincident.com have put together a great visual reference to how different font sizing methods compare across browsers and platforms.

A more techincal discussion of font sizing can be found at here, a Wiki dedicated to CSS.

Welcome!
My name is Todd Harris. A geneticist by training, I now work at the intersection of biology and computer science developing tools and systems to organize, visualize, and query large-scale genomic data across a variety of organisms.

I'm driven by the desire to accelerate the pace of scientific discovery and to improve the transparency and reproducibility of the scientific process.
