I created a crude comparison of the syntax of the various common Markdown extensions to have a better view on what are the most common extensions and what is the most widely accepted syntax for them. The list of Markdown flavors that I looked at was based on the list found on CommonMark's GitHub Wiki.
| Flavor | Superscript | Subscript | Deletion* Strikethrough |
Insertion* | Highlight* | Footnote | Task list | Table | Abbr | Deflist | Smart typo | TOC | Math | Math Block | Mermaid |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| GFM |
| 1. Check out OpenBlas from https://github.com/xianyi/OpenBLAS and check out the master branch. | |
| 2. Build and install to /opt: | |
| a.) Multi-threaded: | |
| make NO_AFFINITY=1 | |
| b.) Single-threaded: | |
| sudo make PREFIX=/opt install | |
| 3. Configure it as your BLAS of choice: | |
| sudo update-alternatives --install /usr/lib/libblas.so.3gf libblas.so.3gf /opt/lib/libopenblas.so.0 50 | |
| 4. Check the configuration to make sure it's selected | |
| update-alternatives --config libblas.so.3gf |
