A refresher on matrix multiplication. Because your math classes were years ago. Here's the order I recommend:

1. TED-Ed video — How to organize, add and multiply matrices - Bill Shillito (only 5 minutes)
2. betterexplained.com — "An Intuitive Guide to Linear Algebra" by Kalid Azad
3. mathinsight.org: "Matrices and linear transformations"
4. Read some of the answers on math.stackexchange.com. You've been studying the general definition of matrix multiplication. You may wonder: "Are there other ways to define the product of two matrices?" These resources will answer, yes, there are other ways, but also explain why this general definition is the standard way.
5. [What is the intuitive way of thinking about multiplication of m

Set up cmder to use msysgit / bash by default

• Install cmder_mini (msysgit is already installed, so no need for full version)
• In Cmder, open settings: Win + Alt + P
• Under Startup > Tasks, add a task called {bash} with the following settings:
  • Task parameters (set icon):
    • For Cmder icon: /icon "%CMDER_ROOT%\cmder.exe"
    • For Git icon: /icon "C:\Program Files (x86)\Git\etc\git.ico"
  • Commands (open Git's bash shell):
• "C:\Program Files (x86)\Git\bin\sh.exe" -l -new_console:d:%USERPROFILE%

Test of internal links in org and in org-ruby

1. link via CUSTOM_ID
   • CUSTOM_ID is added to heading using C-c C-x p (org-set-property)
2. link via text search in headings
   • Requires exact match to heading text
   • Not recommended
   • Very fragile against any change to the target heading
3. link via autogenerated ID
