New Article about Open Graph Drawing Framework (OGDF)

I have added a short article describing a very simple Qt based graph visualizer that uses OGDF to layout an arbitrary graph.

UPDATE: Now with arrow drawing.

Review of “It Follows” from G. R. Wilson

Not related to software, I know, but I like this guy.

New Article on C++ Design for an ImageBlock Class

Hello,

I just published a new article under Articles->Miscellaneous->Design of a C++ Data Class for Images. I write about a class I designed some years ago that I used in an image acquisition and processing framework.  I remembered the class fondly, and decided to revisit it and share a little of the process I went through to design it.  Why do you care? Beats me!

New article on libclang

I have just added a new article about using libclang to discover information about C++ classes, in particular QObject classes. The article describes the approach I took to find special Qt keywords, such as signals and slots.  Look under Articles->Clang.

Introduction

This blog is about software.  In it, I intend to explore and experiment with a number of software concepts that interest me, among them:

• Developing C++ tools with Clang (http://clang.llvm.org/docs/index.html)
• Code generation
• Domain Specific Language development
• Tools for the Qt cross-platform framework (http://qt-project.org)

Most posts will take the form of tutorials with code, showing what I’ve personally learned about a subject.  There is nothing like picking up a library or a tool, doing a project with it, and writing about it to really help one fully internalize what it is all about.  Much of what I know about any particular subject, libclang for instance, comes from tutorials I Googled; my posts may or may not give you much more than those other sources.  My point here is to learn, write, and share whatever I can that may be useful to myself and my readers. And, of course, I hope to receive constructive criticism, advice, and ideas from those who choose to visit here….
