Have a look at online courses. w3school, udemy, coursera have IT related courses if that’s your thing, there are other sites that have online courses too. Free ebooks at gutenberg.org that you can download or read online. Do a search for “text only news”, find a site you like, catch up on the daily news; just looks like a page of text from a distance.
Poor design and implementation. The S in IOT stands for security. So many devices connected to the internet that don’t need to be. I get that it’s cool to control devices from your phone, but why is it necessary to send data from the device to a company’s server so I can retrieve it with an app? I should be able to connect to the device directly from the app, across my local network, without having to send private data to the cloud.
