My professor sent us this little one liner (ok, I had to format it to 2 lines to fit in this blog. You know what I mean) which prints out the current directory tree: ls -R | grep “:$” | sed -e ‘s/:$//’ -e ‘s/[^-][^\/]*\//–/g’ \ -e ‘s/^/ /’ -e ‘s/-/|/’ What’s going on here?

HBO GO has been in the works for a while now, and is an indication of what some networks are trying to do to add value to their subscription rate. Offering video for streaming online is definitely a benefit to a premium channel like HBO. And it is a glimpse as to what the future of online video will hold. I recently got rid of my cable box and implemented a do-it-yourself solution. Since HBO is a premium channel and encrypted, they force you to either buy a cable box via subscription or also a cable-card (which they also charge for). This actually gives me a unique perspective on the service: would I pay for HBO to receive the HBO GO online only offering?

The Bash command environment, which is the namesake of this blog, is very flexible in that it allows you to manipulate the filesystem in many ways. Awk and sed are very powerful tools that allow you to do this rename with a simple one line command. This post will walk you through doing this with a Comma Separated Value (CSV) file and also using a simple regular expression to rename many files.

This is my admittedly minor but I hope useful contribution to the TinyOS development community. TinyOS is an Operating System and development framework for Wireless Sensor Networks and other platforms which has a small footprint and is very energy conscious. The TinyOS source code is available for free online for many operating systems, however it takes a long time to get the environment set up and it is not portable at all. I came across XubunTOS but it did not seem to be in active development anymore, so I endeavored to install TinyOS 2.1 and 2.x from source into a regular Ubuntu image. The most help came from Matt Keally’s Blog. While doing this, I thought it might be useful to many others who wish to develop in the TinyOS framework but might not have the skills necessary to install it. Therefore, I developed this VirtualBox image so that you can….

Currently I am in the Computer Science Master’s Program at West Chester University and I am focusing my research on Location Based Updates in Social Media and their societal and security implications. So you can say I think about this topic more than most normal people do.
FourSquare is a growing service that allows you to “Check in” to restaurants, grocery stores, museums and just about any place you can imagine. However, I have seen several of my friends checking in to locations which, I must say as a security research student, set off warning bells. Although I am calling out FourSquare specifically, these also apply to just about any other location based software where you broadcast your location to other folks, whether they are your friends or the general public. GoWalla and BrightKite are in the same boat.
Without further ado… here is my list of top FourSquare Security Faux Pas (after the break…)
