Recently I plan to start writing a technical blog on medium. I am shocked that medium, a platform which is widely used in the world, do not support LaTeX writing.
Therefore, I have to write and render Latex in hackmd and copy & paste to Medium like this:
σx=y+3 (copy & paste from hackmd)
In addition, if a math formula you read in some paper is so complicated that hard to be translated into LaTeX, I suggest you to use Mathpix Snip. This is a application that automatically translate the formula image into LaTeX, which is very helpful for technical blogs.
