We all need to eat, and we know that good nutrition is an important component of a long and healthy life. Daily we read about genetically modified food and the dangers inherent in a system rife with food that's been altered by biotechnology. And, if you're like me, you begin to wonder, "Where can I get good food?" My wife and daughter have been an inspiration for me to eat better. They want to be able to shake the hand of the person that grew their food. Their inspiration, along with my keen interest in the open source culture, led me to the Open Food Network. read more

Every year on the third Wednesday of November, map geeks around the world (myself included) celebrate GIS Day. Short for geographic information systems, or occasionally geospatial information science, GIS is all about using computer systems to collect, store, analyze, and display geographic data, or really any data that has a spatial component. read more

From the advent of the printing press to the emergence of the Internet, knowledge has become increasingly abundant and accessible. But as we move into the future, I ponder how accessible, interactive, and understandable knowledge will be as more and more individuals are connected to the Internet and as computing technologies advance. How will the techniques by which we share knowledge change? How will the children of the future learn about science? How will the scientists of the future expand our thinking? I think the answer is Jupyter Notebooks. read more

The NMI (non-masking interrupt) system in Linux has been a notorious patchwork for a long time, and Andy Lutomirski recently decided to try to clean it up. NMIs occur when something's wrong with the hardware underlying a running system.

Food and electronics don't usually mix well—unless you're cake hacking. I've been embedding electronics into edible cakes since 2008. And, in 2009, my group won the New York City Yahoo! Hackathon with a cake that showed rudimentary emojis via LEDs with emotions based Del.ico.us tags. read more

eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. You can use it to encrypt partitions and also directories that don't use a partition of their own, no matter the underlying filesystem, partition type, etc. This tutorial shows how to use eCryptfs to encrypt a directory on Debian Jessie.

The Linux distro that doesn't stop Review OK, it was a slight delay – one week – but the latest Fedora, number 23, represents a significant update that was worth waiting for.…

The last chapter of The Open Organization talks about how a leader in an open community has to be a catalyst, "an agent that provokes or speeds significant change in action." When I read this definition, say it out loud, and reflect on my connotations of this word, I sense a degree of urgency. I don't think of a catalyst as necessary calculated, so I would like to explore the idea of a "calm catalyst." read more

Sometimes, we need to completely and irreversibly wipe all data contained in a disk to keep them from falling into the wrong hands. This may not be something we are doing on a day to day basis, but if you want to do it, you should do it right and ensure that the data cannot be recovered by experts.

More and more journals are demanding that the science being published be reproducible. Ideally, if you publish your code, that should be enough for someone else to reproduce the results you are claiming. But, anyone who has done any actual computational science knows that this is not true.
