• Day 26: using combinators in :has()

  It’s time to get me up to speed with modern CSS. There’s so much new in CSS that I know too little about. To change that I’ve started #100DaysOfMoreOrLessModernCSS. Why more or less modern CSS?

I'm very strongly against programs making noises at me and normally turn this stuff off, but this time around I couldn't find an obvious way to do it in places like kdiff3's own application settings. Normal people might reach for their desktop's general settings, but for my sins I don't use a desktop environment; I use a custom setup built around fvwm as my window manager.

• Command to view DNS records for a Domain in Ubuntu Linux

  The Domain Name System (DNS) is a central directory service that is responsible for name resolution on the Internet. If problems arise, it can sometimes be useful to take a look behind the scenes and, for example, to determine an IP address for a hostname. A useful tool for this purpose is nslookup, which we will introduce to you in more detail in this post.
