i've seen some examples that suggest it might not be as cut-and-dry as that. i don't have the url handy, but some time ago someone in one of this discussions linked to a publicly-accessible record of clearance decisions. the one that jumped out at me had a guy who'd been a drug addict and involved in dealing in the past--he was clean now and fully informed them about it during the screening, and was approved.
i went to academic summer camps basically from sixth grade on (Duke TIP-affiliated stuff), and one year i took chemistry class. one of the three weeks was "uncontrolled oxidation" week. lots of fun. :) the biggest takeaway was that potassium perchlorate plus almost anything equals cool. i think my favorite was equal parts potassium perchlorate and sugar in a half-coke can. take outside and add a couple drops of sulfuric acid--ten-foot cone of flame.
for reference this would be, hmm, i think 1995? somewhere between 94 and 97, anyway.
ethanol burns relatively cool (as do (some of?) the other alcohols). the problem is that it often burns above the ignition point of its carrier substance, which itself burns much hotter. e.g. calcium acetate/isopropyl alcohol gel (lab sterno) is perfectly safe to burn in your hand, but only until the alcohol runs out--it will light the calcium acetate, which is not remotely safe to burn in your hand.
hand sanitizer is usually an alcohol in water and a thickener (glycerin, etc.). i'd worry a bit about the same effect. (not that i actually know what the ignition and flame temps of glycerin are....)
"Users may be experiencing issues" is not the passive voice (not that you explicitly said it was, but IMAO you implied it), it's the continuous aspect, modified by whatever an auxiliary like "may" does. (this is where my grammar vocabulary starts to run out. conditional continuous maybe?)
passive would be "Issues may be being experienced by users".
istr a ds9 novel (yes, i read some) where they had to replicate some machine guns to deal with invaders who had perfect shielding, but only against energy weapons. there were security overrides involved, but it had a large collection of projectile weapons to choose from once it was unlocked.
you ever see American Graffiti? one thing that really stuck with me was the bit at the end where they're boarding a plane--it was just walk out onto the runway, present your ticket and walk up the stairs.
to do that nowadays you have to be flying private....
i've flown international business class on luxury airlines twice (once on singapore on the company dime, and once on qatar through a random complimentary upgrade). the service is just staggering--never mind the full-flat bed-seats, the unlimited free liquor, the gourmet food, or the entertainment center with a full array of power outlets and usb and video ports so i could run any device and content i wanted, what really impressed me was the rose in a vase on my table when i boarded, and the pajamas in the care package (with the slippers and eyemask and so on).
i'm splurging and flying "premium coach" (or w/e the hell they call it on Virgin) on my next vacation; we'll see how it compares....
Funny thing most Americans don't know is that international coach is really decent too. E.g. I've never been on an intercontinental flight without unlimited free alcohol aside from on Delta, and any plane put together in the past few years will have USB/power sockets in every seat.
for someone who'd never flown anything other than coach, the experience was mindblowing, especially since the upgrade was only $50 at the airport.
i'd love to fly first or business again when i eventually go to europe, but as a hypothetical exercise i checked prices, and a firstclass roundtrip tickect is roughly $20k and business, though much better, is still $6k (i just checked lufthansa.com for sfo<->fra leaving august 4 and returning sep 1, so i'm sure better deals exist). If I flew coach, the whole vacation could be $6k.
Hence, only lubutu's comment ("-R is the recursion flag for ls, cp, rm, etc") is true, while _delirium ("-R is the POSIX-standard flag for recursive grep") is wrong, which means AIX is free to do whatever it wants with both the -r and the -R flags.
