  Identity and Access Management (IAM) isn't the same thing as (single sign on) authentication, although I believe it's connected to authorization if you take the 'Access' part seriously, and also a bunch of IAM systems will also do some or all of authentication too so everything is in one place. However, all of these things can be separated, and in complex environments they are (for example, the university's overall IAM environment, also).

  For as long as we’ve been doing SEO, we’ve been operating inside a URL-shaped worldview. Google’s early systems indexed and ranked URLs. PageRank flowed along links between them. Analytics tools counted visits per URL. Keyword research mapped to URLs. Content strategies were literally drawn as sitemaps. The URL wasn’t just an address – it was the atomic unit of the web.

  Fortunately, Ubuntu ships with a Startup Applications utility, which makes it easy to enable or disable applications that start automatically when you log in. When I need to make such adjustments, I always keep startup applications to a minimum.

  I've had it happen before. Back when drives consisted of spinning, magnetic platters, that dreaded "tick" was a sure sign a hard drive was failing. Once upon a nightmare scenario, I waited too late and wound up losing everything on my drive. Sure, I could have recovered that data, but at a pretty high monetary cost.

  Since then, I've always been vigilant about checking for bad blocks and sectors on hard drives.
