OverviewA firewall is a hardware or software network security device that sits at the juncture between two networks to control what information is allowed to pass between those networks. Usually, the two networks are an organization's internal network and the Internet. A firewall's primary role in information security is to protect computers on the internal network from intentional attacks. Internal network firewalls consist of internal computers and systems, and may be firewalled internally based on risk. A border firewall is intended to prevent unsolicited and...

Knocked My Socks Off!My coworkers and I attended our first JAMF Nation conference this past October. The last session I attended on the first day knocked my socks off. Bryson Tyrrell of JAMF showed off an iPhone ordering script he wrote in Python and Tk. I've written some Tk, but it was a long time ago and I remember it being an uncomfortable experience. It seems a lot has changed. His script included an image that would dynamically change based on user interaction. It was...

OverviewIn this post we will be talking about file descriptors and increasing limit descriptors in OS X Yosemite. File descriptors are limited by the OS. This causes some applications and services to return errors. By increasing the limit of file descriptors we can reduce the amount of "too many files open" error. What are File Descriptors?A file descriptor is used by the kernel to represent an open file that it needs to refer back to. These files are placed into an array and given an integer. The integer...

OverviewXcode is Apple's development environment. It's used to develop applications on Macs, iOS devices like iPhones and the Apple Watch. It also includes the new language Swift, which is becoming very popular in higher education. However, Xcode requires users to have "_Developer" group privileges to allow the debugger and emulators to work correctly. We give our users only the minimum privileges they need to get their work done and we take great pains to secure our environment. We felt giving every user "_Developer" rights was...

UpdateSince this post was first written, I've discovered some people use Anaconda Python. After investigating, it looks like Anaconda is a much simpler solution. To deploy it, I installed both Anaconda 2 and 3 to [crayon-5d61f1517f1d3042215776-i/] , and then modified the [crayon-5d61f1517f1d9324549597-i/]  and [crayon-5d61f1517f1db089394818-i/]  files accordingly (as shown further down in the article). OverviewThis post walks you through the steps to create new installations of Python on an OS X machine you administrate. The end-goal is to have standalone versions of Python 2 and 3 that you...
