OBS is awesome! Open Broadcasting Software, also known as OBS Studio, is an awesome piece of free and open source software that lets you capture audio and video from a wide variety of sources: screen capture, webcam, audio capture from the system, from an external source, from static images, slide shows, etc. It’s been awhile since I’ve used OBS to capture the desktop of one of the systems at work, an ASUS M51AC desktop with an i7-4770 CPU, 16GB of RAM, and a 256GB SSD. I installed OBS 30.0.1 and started to record a video of the desktop, using the webcam microphone for audio. After a bit of tweaking, adjusting Xubuntu’s microphone sensitivity, I managed to get audio recording correctly so audio levels did not “clip” (go into the red) in OBS. ...

About findmonitor.sh Note: Note: This script is NOT compatible with systems running Wayland. We use Xubuntu Linux at our project. The Working Centre’s not-for-profit Computer Recycling Project sometimes receives donations of many monitors all at once. Our previous method for handling monitors was to set them up, run them through a bunch of tests, print a label on our label printer, and enter the monitor into our point of sale. This method hasn’t worked very well for us when we’ve received a lot of monitors all at once. Large amounts of monitors were sitting untested for awhile because we didn’t have the resources to do the old process for each monitor. We needed a faster way to figure out some of the details of monitors, and make them easier to sell without needing to create labels and enter everything into the point of sale. ...

Diminishing returns after 6 cores, but not for all media Handbrake is a video transcoder. It’s normally used to convert and compress video from a format into a more compressed format. Handbrake comes in a command line version, handbrake-cli, and a graphical version, handbrake. I’ve seen it mentioned several times that Handbrake is best at 6 cores or less, after that the encoding returns are diminishing. I thought this was the case with some of my experimentation, but it seems the answer is more complicated – it depends. ...

About the script I wrote the hardware.sh BASH script to make it a bit simpler for volunteers at The Working Centre’s Computer Recycling Project to figure out what hardware was in a computer. For more than a dozen years we’ve been asking volunteers to gather information from the BIOS, or using phoronix-test-suite under our PXE booted Debian Live environment. Volunteers would write the information on quarter page-sized sheets we would attach to each computer. While this was a useful function to help volunteers get to know hardware in a computer, there were a few problems with this method: ...
