Flowing Fix: Generating QRcodes

Quick Response Codes (QR codes) are a type of two-dimensional barcode (or matrix barcode) which allows for encoding of information that can be read rapidly. For more about QR codes see https://en.wikipedia.org/wiki/QR_code

LaTeX can generate QR codes: 

To enable this capability in LaTeX, include the qrcode package (https://ctan.org/pkg/qrcode?lang=en) A tutorial with simple example code (see Example 11) can be seen at https://www.hydro-perturbations.com/help-files/latex-quick-examples

Flowing Fix: How to easily determine the LaTeX code for a symbol

Every have trouble remember the code to a LaTeX symbol?

Typically when you want to find an infrequently used symbol in LaTeX you often have to refer to the comprehensive symbols list: http://ctan.math.utah.edu/ctan/tex-archive/info/symbols/comprehensive/symbols-letter.pdf. However, this can be time consuming and difficult to find the symbol you need.

Detexify can help find the code to LaTeX symbols simply by drawing what they look like.  Try it out for yourself, and you will shortly have a new bookmark for Detexify in your browser.
