These work well, and they are reasonably easy to use. However, they aren’t without their problems. So maybe try an IR time of flight […]
What’s Forgotten Internet? It is the story of parts of the Internet — or Internet precursors — that you might have forgotten about or maybe you missed out on them. This time, we’re looking at Unix-to-Unix Copy, more commonly called UUCP. Developed in the late 1970s, UUCP was a solution for sending messages between systems […]

In fact, you’ve spotted one of the world’s most bizarre architectural phenomena. Santos is an interesting contradiction—it’s a sunny coastal city with pristine beaches that also plays host to a bustling […]
Much has been written about the demise of physical media. Long considered the measure of technological progress in audiovisual and computing fields, the 2000s saw this metric seemingly rendered obsolete by the rise of online audiovisual and software distribution services. This has brought us to a period in time where the very idea of buying […]
