This is a fast guide on configuring OS X to act as an L2TP VPN Server. This can be accomplished with Apple’s Server App, but if you don’t mind running a few Terminal commands and adding a couple configuration files manually, you can save yourself $20 and go out to eat instead.
This guide also includes a workaround for a known bug in the general release of OS X 10.9 Mavericks in its implementation of racoon that prevents remote clients from being able to connect to your VPN server.
Here’s a relic from the past–an old school research paper. Debates around computing ethics continue on, so I thought I would toss some of my old thoughts out there. The conclusion I had when I wrote this is still true today as we see some states in the U.S. implementing school programs to educate kids on copyright, and the continued rise of 3D printing make the physical< ->virtual analogy more realistic.
The original abstract reads:
This paper explores the complex world of computing ethics. The paper revolves largely around philosophical debates. As with most, if not all, philosophical debates, there is no clear-cut solution. Indeed, after exploring the literature on the subject, more questions were raised than were answered. As such, this paper aims to bring some of those questions to the forefront for the reader to consider and ponder as an independent exercise.
On the first day of the Colorado High Park Fire (June 9) I was in the Red Feather Lakes area, so I took a couple short time-lapse videos of the smoke plumes. As of this writing the fire has burned more than 82,000 acres and destroyed over 190 homes, and is only partially contained.
Both time-lapse sequences consist of around 600 photos taken at 1 second intervals on my Nikon D5100 and rendered at a rate of 24fps. In other words, each video depicts roughly 10 minutes. I was on the Northeast side of the fire which was still several miles away on the South side of Hwy 14. I hope to go back to this same spot in a couple weeks for a before and after shot.
I spent more time tweaking the first sequence which is why it contains significantly less flicker than the second sequence. I was quite happy with the way the time-lapse videos came out considering that these are the first that I have ever created.
