Yeah, lots of people out there saying "leenucks doesn't have a dns cache!!1!" — well, recent versions of Ubuntu do ootb, and just restarting NetworkManager doesn't clear it for some ungodly reason… flush it with sudo systemctl restart systemd-resolved

}Switching to Picom (Compton) on the MATE desktop
You may have read some convoluted (and outdated—Compton was abandoned in 2017) tutorials on the matter like MakeTechEasier's, or perused the excellent Arch Wiki article's page on it to some despair, but if you are just a layperson who installed the MATE desktop for e.g. Ubuntu 20.04 (Fossa) and wants a slightly faster (i.e. GPU-accelerated) environment, there is a workaround that doesn't take too long to set up: …

WordPress: Restrict MathJax to a class

To avoid triggering a math rendering engine on unrelated use of $purious dollar sign$, while activating it when $\text{necessary}\wedge\text{appropriate}$, I decided to restrict them to only elements with .language-mathjax.
