The author points to using grep and Xargs and some other tools to quickly update a package. That's the key here. These bash/Linux utilities are productivy boosters for all the Linux and Mac/bsd people out there. I can't imagine living without them and they're necessary for any system I develop on (which is currently a Mac).
For devs that do heavy Linux work (but have stuck with a Mac OS for GUI/app reasons), is it time to move (back) to Windows? If so, what would be a good laptop to get at the moment?
I'm personally using a Dell XPS 13 (2014), soldered in RAM, but I did buy an ultraportable and 8GB is more than sufficient to do my all my personal work on. Work supplied me with a Lenovo W540 that is substantially more flexible, but it weighs as much as a couple bricks and I usually just leave it at home on the dock.
And it's pretty damn light for a 15" laptop. Easily one-handable (I think it's like 2 pounds IIRC).
And what's great is that you can crack it open and replace stuff - I swapped out the hard drive and replaced a malfunctioning battery myself with just a torx screw driver (super tiny torx, but still, no glue or special tools or anything).
It was pretty expensive - like $1900 IIRC. You're paying for the high res screen, better build quality, and thinness/lightness. But it's still like $500+ less than an equivalent macbook.
