Speedy Internet: you know you need it.
And, please don't put your super fast fibre optic line behind a crappy wifi router. (yes, wifi is a must, so we can go and chill out on the sofa if we need to.)
Also: everything is on the Internet already. Solutions, advice, stuff to read, cat videos for the in-between moments, and The Wheel, which we won't (and shouldn't) have to reinvent. Perfect for the Copy/Paste Programmer.
