Create and Use Barcodes to Simplify Your Book List
January 9th, 2010
barcode example (converted to png)
In keeping track of my books, I have been looking for a simple way to generate barcodes as individual graphics that I could embed in my book list. I think I’ve found it: Dan Bornstein’s Barcode Server, which I found at the BarcodesInc’s UPC/EAN Barcode Generator.While the online version is nice, I wanted something a little more flexible and robust, so I downloaded the C source code.

Interactive data visualizations with R
January 3rd, 2010Jeroen Ooms, a visiting scholar at UCLA’s Department of Statistics, has been very busy with R — he has two wonderfully slick online apps where users are able (for free) to visualize datasets using R’s ggplot. If you’re interested in R, stocks, or just data visualization, you’ll find something of real value in his applications.
the preservation of favoured traces | ben fry
December 31st, 2009I’ve always enjoyed a nice graphical diff, like WinDiff, WinMerge, or KDiff3 — something that shows how a document has changed since some previous incarnation. Ben Fry, father of Processing, has taken this idea to an extreme with Darwin’s Origin of Species by showing how Darwin’s book changed with each revision, graphically depicting the variations in the document by chapter with each revision. » Read more: the preservation of favoured traces | ben fry
Intro to The R Programming Language: For Programmers
August 31st, 2009As someone who’s new to R and curious about what it can do, one of the first questions I ask is how does it compare to Java, C#, Perl, etc. (Insert language-of-choice here.) Fortunately,John Cook has answered that question with his blog post: The R programming language for programmers coming from other programming languages. Take a few minutes to check it out and see for yourself why R is the up-and-comer.
Rosetta Code
August 31st, 2009One thing I’ve always enjoyed is learning something new, especially a new language. First it started with human languages, but over the past few years (well, more than a few!) I’ve enjoyed learning new programming languages. From Lua to REXX to Icon to Processing (which, technically, isn’t a language but more like an environment) and many others, I’ve loved tinkering with new languages. Now, I found a resource online that lets me compare the various languages. It’s called (appropriately enough) Rosetta Code. Look for a solution to a problem by language or by problem. Fun stuff! Gotta go… Lots to learn…
Google’s R Style Guide
August 15th, 2009I’m still pretty new to R, but find that Google’s using it in lots of places, like MapReduce. Google’s R Style Guide outlines the directions to R programmers. It’s an interesting read — very simple and efficient. (Thanks to the post on Revolutions blog for the link.)
