How is metrics aggregation different from log aggregation? Can’t logs include metrics? Can’t log aggregation systems do the same things as metrics aggregation systems?

If you lurk around enough audiophile-related sites, you may stumble upon writers claiming a difference in sound between the same music played back in FLAC or WAV format. This article on The Well-Tempered Computer does a nice job of exploring this concept, both from the perspective of those who don't believe such a thing is possible and from those who think there is a difference.

Sometimes, the requirement is to know more about individual elements in a path - what type of file it is, who is its owner, and more.

If you're a Linux user and have been for years, sometimes you can forget that much of the desktop world is still on Windows. Or perhaps it's not so hard to remember. Many of us hold day jobs where we're not lucky enough to be able to choose our own operating system and are stuck with whatever IT has gifted us. Or, perhaps, you still keep an old Windows PC around for running that one application that just isn't available on Linux.

I don't know where to begin—and I mean that in a very positive way. I can best describe Valley of Genius: The Uncensored History of Silicon Valley (As Told by the Hackers, Founders, and Freaks Who Made It Boom) as a "literary documentary".
