Free Hotel Wifi with Python and Selenium Recently I took my annual leave and decided to visit my friend during the holidays. I stayed at a hotel for a few days but to my surprise, the hotel charged money to use their wifi. In  $DEITY ‘s year  2000 + 18 , can you imagine? But they are not so cruel. You see, these generous people let you use the wifi for 20 minutes.  20 whole minutes.  That’s almost half a Minecraft video. If they let each device use the internet for a limited amount of time, they must have a way of identifying each device. And a router tells devices apart is by their MAC addresses. Fortunately for us, we can change our MAC address easily. Enter macchanger There is a really useful command-line tool called macchanger .

Are you about to begin an important Vue project? To ensure you start with a solid foundation, you might use a template (aka boilerplate, skeleton, starter, or scaffold) rather than starting from npm init or vue init. Many experienced developers have captured their wisdom about building high-quality Vue apps in the form of open source templates. These templates include optimal configuration and project structure, the best third-party tools, and other development best practices. Vue Starter for isomorphic PWAs with Vue Unlike Vue CLI 3, which is optimized for flexibility, templates are opinionated. It's important, therefore, to choose the one that fits with your development philosophy and has roughly the same features that you'll need out of the box.
