I know you're an AC, but lest some reader thinks your reply is insightful:

* "immuno-compromised" includes people taking immuno-supressants, such as those with Crohn's, Ankylosing Spondylitis, etc.
* some people attending may have a newborn or elderly at home, and they could take a new infection back home with them

I find it increasingly hard to understand what value people get from trolling on slashdot, now. I mean, the value proposition has always been questionable, but now that /. is well past its heyday, the comment sections are a ghost town. There's not really anyone around to give trolls the attention they crave.

One of my mantras is '!@#$ing Microsoft'

Recently had a teammate show me a simple rewrite of one (Microsoft SQL) line: orig: a is not null or b is not null, new: not (a is null and b is null). Logically equivalent. From two hours to twenty seconds?!?

Hold up. You are claiming that an application of De Morgan's Law on that simple SQL query sped up your run-time by 360x?

I don't have much experience with SQL, so take this as just a request for info with merely a tinge of scepticism (rather than full-on scepticism.) But:

(assuming 'a' and 'b' both represent SQL queries)

* Your 'orig' looks like it would often get away with just 1 query (i.e, if 'a' proves to be not-null, then no point querying 'b')
* Your 'new' looks like it would always perform 2 queries

Which leads me to the following observations:

* 'orig' actually looks to be more performant that 'new'
* Even if you just accidentally swapped your telling of 'orig' and 'new' in your comment here, still at best you are looking at a 2x speed up, not the 360x speedup you are claiming.

Systems programmer here, for a semiconductor company. I've used a Chromebook Pixel for 5 years now, at work. I used the browser for our intranet sites (including Outlook web access) and an NaCl-based SSH client to access bigger iron for development (tmux/vim/gcc). Chrome OS worked amazingly well for me as a thin client, where I could work in the office or on the road, and never store company IP on it. Spreadsheets and presentations were done with Google Docs. I did not feel in anyway like I was using a Fisher Price toy or Coleco computer. My only gripe was the mapping of the F1 - F10 keys... which was a problem with the physical device, not the OS.

Now that that model has been EOL'd for new Chrome OS updates, it has been repurposed as a Gallium OS machine. The only improvement that has given me over Chrome OS is X-forwarding.
