RS-232 PC Serial Port Pinout Conventions
At one point, the RS-232 9-pin Serial Port used to be a common connector on the back of every computer. But with USB being a much better protocol and easier to use, the serial port has just about disappeared from modern desktop computers.

If you have a need for a serial port, then an IDC10-to-DB9 serial adapter might be required. I had just such a need recently and discovered that there are two industry standard pinout conventions in use, the AT/Everex and the DTK/Intel. If you want to know more about how I discovered this and the differences, then continue reading.

What is the difference between drop frame and non-drop frame timecode?
Early in my career, I needed to learn about timecode, especially the differences between PAL, NTSC, drop frame, and non-drop frame. For some reason, I simply couldn’t grasp the difference between drop-frame and non-drop-frame. I couldn’t even find the reason why there was a difference. Eventually, after many questions and many hours of reading, I discovered that the key to understanding the difference was in learning the reason why both flavors exist.
That was over twenty years ago, and if you’re anything like I was and would like some clarification, keep reading.
Understanding UMASK with Linux and Samba
Have you ever been confused with the Linux environment UMASK? How about trying to setup permissions with a Samba file server? Displaying and setting the umask for both the Linux environment and a Samba server is very easy. In this article, I’ll explain what a UMASK is and how to display and change the current value.
