Fault tolerant computing
As a first step to writing my own simulation code while attempting to do something useful, a few days ago I started writing a code to explore failure and recovery from failure in a distributed computation. By failure in this case, I mean when one of the computation units goes down. My test system is N harmonic oscillators on N nodes (or processes on a shared memory machine). Read More …
The Intersection of Productivity and Joy (over the past months)
Since last we spoke a couple of months ago, I had a hell of a time personally: I moved house, went from one location to another too often, had a major and very stressful financial crisis and had some rough times with friends which rocked the emotional boat. Although there are many things which didn’t Read More …

This is just a taste of what’s to come. Get Kliq on the iPhone App Store at http://itunes.apple.com/lt/app/kliq/id412169676 or visit http://kliq.in. Read More …
Kliq app field testing in Columbus, Ohio
The Kliq beta application has recently been submitted to the iPhone app store. Kliq allows you to schedule a meetup with nearby facebook friends or a friend-of-friend at a nearby location in three thumb taps. A tech nugget and anecdote: Kliq uses SimpleGeo to go from the user’s GPS location to a set of possible Read More …
Wikileaks Research Project, midpoint report
A week ago I hatched a plan to educate myself in a more structured manner on what exactly Wikileaks stands for, its history, and its possible futures with the idea of developing a more concrete and informed opinion (and since I have a habit of taking action with respect to my opinions, thereby guiding my Read More …
Phygg featured on MIT Technology Review
Phygg featured on MIT Technology Review. Phygg was down for a bit today due to overload, upgrading my hosting and starting to do some analytics. Having your site go down is a tangy bitter shot of success and failure in the same glass. Here’s to steady uptime and a great phygg community to come! Read More …
Introducing phygg
My Sunday afternoon recover-from-jetlag hack was creating http://www.phygg.com. Phygg is designed to help sort through physics papers and discussion topics related to arXiv.org in the style of digg.com, initially focusing on astrophysics. I’m going to be using phygg to track papers I find interesting, so feel free to follow the rss feed. In addition, I’m hoping to convince a few of my astrophysicist colleagues to join in on the posting and voting, so stay tuned. Read More …
