 So if I open a math equation in a new tab, it will show the link to en.wikipedia.org (e.g. [https://en.wikipedia.org/api/rest_v1/media/math/render/svg/1cb5e652b8488ecf389681e4bff97278f3df0be7 C-statistic]) created in my [https://taichimd.us/mediawiki/index.php/Survival_data#C-statistics Survival data] page. If I host mediawiki on Rasp Pi3, a mediawiki page with lots of math symbols will be too slow to be loaded.
