Save CT Images from *Scan of the Month*
I love seeing the monthly updates on Scan of the Month, a website that posts detailed CT scan renderings for selected themes. This website is a portfolio created by CT device company Lumafield. Lumafield is a company that was started by a team of engineers who had firsthand experience with trying to solve hard problems and being let down by the tools on hand. Lumafield is also a company, that while in stealth-mode, decided the technology they were building was just too dang cool to keep quiet about.

What is the NVIDIA Container Toolkit?
The NVIDIA Container Toolkit is a set of utilities and libraries provided by NVIDIA to enable containers to use and share NVIDIA GPU resources. The toolkit is container agnostic, supporting several common container runtimes including Docker and Podman. It appears to present GPU/CUDA features to software running within containers on the host with the NVIDIA GPU. The supported platforms seem to be specifically GNU/Linux distributions (Debian, Ubuntu, Centos, Fedora, Open Suse, and Amazon’s Amazon Linux AMIs) on typical amd64, arm64/aarch64 hardware.

Manually customize bash terminal prompt look
The prompt text that bash interprets and uses is set with the PS1 environment variable and is usually specified in ~/.bashrc. I have been manually tweaking my bash prompt look and feel to make some of my work project use-case tasks easier. The combination of default style changes, and specific prompt elements added for active environment or sourced environments should make terminal-based project management a little easier. A little searching allowed me to discover this website that allows you to interactively customize the prompt contents and style with common components. https://bash-prompt-generator.org/

Who knew you can make an animated GIF with *convert*
Another thing that comes up infrequently so it is hard to remember! This method of creating an animation from a set of individual images as frames is one of the easiest I have ever seen. (Get out of here FFMPEG!) ImageMagick’s convert animation example command convert -delay {centiseconds} -loop {loop-n-times} *.png output.gif Here is an output made with convert from .png frames using a 25 centisecond frame advancement time.
