Plex media server

As someone with a lot of digital content including movies, TV shows and music, I’ve always been on the lookout for new and useful ways to get the media where I want it. Previously I’ve used a Raspberry Pi computer with KODI to organize and play my media on my main TV, but I was […]

Sediment Traps: Historical Trends and the Promise of Inovation

[NB: The first entry in this series was published here, Introduction to Sediment Traps, which covers the motivation, use and issues of sediment traps.] Although validation of the data was lacking, sediment traps (or sedimentation traps as they were once called) were being used by the 1970s in the study of lakes (Davison et al., 1982; […]

Analyzing YSI data through clustering

Update 10/13/15 – Minor improvements to code and an update to the latest findings. CTD data (conductivity, temperature and depth) from a YSI provides a quick and methodologically simple way to estimate the current water column state by, literally, dropping an instrument off the side of a boat. During each deployment the YSI records the […]

Markov Chain Monte Carlo: A Practical Introduction

Markov Chain Monte Carlo simulation sounds, admittedly, like a method better left to professional practitioners and the like; but please don’t let the esoteric name fool you. MCMC, as we like to call is, is a powerful yet deceptively simple technique that can be useful in problems ranging throughout science and engineering. Since this promises […]

Which Witch is Which

This post is an elaboration of an iRKernel Notebook which can be found at http://misc.tkelly.org/Which_Witch.html. For a previous article on the iPython Notebook, see here. Every programming language comes pre-packaged with certain basic functions, or methods, that are considered standard. These generally include methods for sorting objects, conversions between basic types (e.g. integer float string), […]

Working with HYCOM

So far this week I’ve been focusing my energies on getting the Hybrid Coordinate Ocean Model (HYCOM) up and running on my computer. For those of you who don’t know what HYCOM is a modeling platform sponsored by the National Ocean Partnership Program which includes–among others–FSU. Simply put, the HYCOM platform is a powerful ocean-atmospheric […]

How Twitter Improved my Ecological Model

For a last couple weeks I’ve been working on a marine ecosystem model using a technique called Inverse Modeling(1)I’ll be sure to do a writeup on what Inverse Modeling is and what makes it interesting in the future.; and while there’s been lots of progress, I’m starting to get to the point where the model takes some […]

Ray Tracing, or Why I bite off more than I can chew

I’ve spent countless hours and a considerable about of energy on getting my ray tracer up and running, and this is what I have achieved: While it may look like modern art(1)Actually, since art exists independent of intent and as a result of a observer-entity interaction, this picture would be “art”. Whether it is modern […]

Paper of Note: Fast, Minimum Storage Ray-Triangle Intersection

Introduction Raytracing is modern computer graphics technique used to render life-like images for videos and animations. While it’s a relatively modern technique–coinciding with the birth of digital modeling–the inspiration for the methods can be traced back to ancient Greece. While some Greeks truly believed that our eye’s emit the ability to see and not that our […]
