• How To Crop and Zoom in OBS

  OBS (Open Broadcaster System) is a remarkably powerful tool. With OBS we can record videos, using various scenes and sources to create broadcast quality shows, for free! OBS can also be used to livestream via many different services, and using a few plugins you can also interact with your community.

  Recently I had a need to record video from a 4K USB video capture device. The video source was the latest LattePanda Sigma SBC, which I was testing using Steam for a review. Steam’s built-in FPS counter was a little small (yes I could install another FPS counter, but that would incur a performance hit), so I duplicated the video source, laid one on top of the other, then cropped the FPS counter area, followed by a zoom in.

  Here is how I did it.

• Unix is not POSIX

  GNU Grep's defense of its decision to ruin and then drop the 'fgrep' and 'egrep' commands is that these commands aren't in POSIX. There are a number of problems with this, but one of them is that Unix is not POSIX (and conversely, POSIX is not Unix). In practice, POSIX partially overlaps with modern Unixes, so just because something isn't in POSIX is not any sort of reason for a Unix to not have it (and never has been). Unixes have always had many things that aren't in POSIX.
