About

This blog is by me, Peter Coates, a long-time software engineer. At Hortonworks I did solutions engineering, consulting, and product support. I’m not with  Horton now, but I’m using HDP in my new job at a company that likes a low profile.

The blog has a pro-Horton bias but I don’t speak for Hortonworks in any capacity, so please assume that any mistakes or crackpot opinions are all mine. Most of what you’ll find in this blog concerns basic core Hadoop but HDP is a big distribution with many other components including HBase, Storm, Kafka, Atlas and Ranger, to name just a few.  There are also some articles on non-Hadoop big data projects I’ve done.

My interest in Hadoop developed from a background in other distributed computing technologies, including CORBA, Tibco, JMS, Gigaspaces, and NoSQL databases. I’ve mostly used Java for the last few years, but I’ve worked with C, Smalltalk, C++, and many other languages.

I have a side interest in probabilistic algorithms for processing information in unusual ways that aren’t necessarily classic “big data” (see the blog entries on analyzing Twitter and estimating Levenshtein distance from signatures.)

Before discovering the joys of computer science (I got my MS from Columbia University in 1992) I was a painter and sculptor—there are some samples below. I also have a Website on stone carving called Sculpture Wiki, that is a manual a technical manual and a collection of information on aesthetic issues and history. I’ve written about books for The Second Pass.

SculptureWiki.com. uses some interesting Web tech. The content is written using the LaTex typesetting language using the Hyperlatex package instead of the usual HTML. This allows a single body of text to be automatically issued as both a Web site and a book when the LaTex is compiled. In addition to the normal LaTex markup, certain elements which are appropriate to one or the other can be tagged to be handled appropriately for one or the other. Any change to the content automatically appears in both—there are no extra steps to issue the book. The book can be downloaded from the main page as a big PDF file, leaving out the ads, page links, and other elements that are only appropriate to the Web. There’s probably some way to machine translate PDF into the other standard formats if I ever get around to investigating.

Here are some samples of my work in the plastic arts:
