Ploopy is a company located in Canada that makes open-source mouse with 3D printing material. They’re especially known for creating trackball mouses with modern sensors. Ploopy devices use QMK firmware by default, this gives you a lot of flexibility to customize your mouse.
Ploopy Classic is their most iconic model, a modern, open-source 3D-printed imitation to the Microsoft Trackball Explorer.
Zotero is a free, easy-to-use tool to help collect, organize, and cite research papers. This is widely used, and really helpful for graduate students / researchers.
What’s nice is Zotero handles syncing of all the articles you collected over the years as well as their attachments (most likely PDFs of the corresponding article) on different machines. The actual metadata of the articles that you saved are stored on the zotero server for free, and to my knowledge, does NOT have a limit. However, there is a limit on the attachment files stored on the Zotero server, i.e. the actual PDFs for the articles. If you’re on the free-plan, the upper limit quota is 300MB. For 2GB storage, you would need \$20 per year, and 6GB for \$60 per year. See pricing here .
Unified Modeling Language (UML) diagram is a standardized visual diagram used to design and document the structure and behavior of complex software systems. Here is YouTube video that talks about the diagram usage. There are many different types of diagram, and here I keep a record of them for my personal usage.
One of the ways to create a UML diagram in Org-Mode is to use PlantUML , a simple language used for writing UML diagrams.

Here I keep track of the basic syntax or classes used in AMReX for my personal notes.
GDB , the GNU Project debugger, is a useful debugger for many languages (C, C++, Fortran, etc). Here I keep a set of useful commands for my records.
To use GDB, compile the program with debugging information.
For standard C++ program, add -g flag when compiling, i.e.
something like
1g++ -g -o myprogram myprogram.cpp
For AMReX related application codes like Castro, compile with
DEBUG=TRUE, i.e.
Hugo is a static website generator written with GO, providing easily capability to convert markdown files into a website. For those who use emacs Org mode , one can use ox-hugo to convert Org files into markdown files that will be compatible with Hugo. Hence the workflow is:
