That's not correct. See 14 CFR 61.113 (c) A private pilot may not pay less than the pro rata share of the operating expenses of a flight with passengers, provided the expenses involve only fuel, oil, airport expenditures, or rental fees.
edit: the exceptions of the CFR are (b) through (h) but (c) is the most typical
and you're right (if you're getting at what I think you're getting at).
The argument is that expense sharing is compensation, but it is allowed under the FARs in specific circumstance. Difference here being that the combination of holding out on a public website and receiving compensation via expense sharing put it in common carrier land.
Which does seem to make sense under current rules.
Sharing expenses is compensation and the reg alludes to that fact in part (a) and by virtue of the list of the exceptions to said reg. If you really need a concrete example that includes the "compensation or hire" verbiage look at exception (b) of the reg.
(a) Except as provided in paragraphs (b) through (h) of this section, no person who holds a private pilot certificate may act as pilot in command of an aircraft that is carrying passengers or property for compensation or hire; nor may that person, for compensation or hire, act as pilot in command of an aircraft.
(b) A private pilot may, for compensation or hire, act as pilot in command of an aircraft in connection with any business or employment if:
(1) The flight is only incidental to that business or employment; and
(2) The aircraft does not carry passengers or property for compensation or hire.
Thought it was either written by Russ Cox or it had something to do with Roosters. But seriously, it's more of a personal problem if someone can't make the minute mental leap to discriminate between cox and cocks-the name is perfectly fine and doesn't need to be changed.
I just started looking at Rust and like what I see so far. I may be able to help; I worked on the Windows port of Go and put together the MinGW build environments as well as the binary installers.
I personally don't know what's necessary now, but if you feel like joining #rust or #rust-internals on irc.mozilla.org (which I recommend :) ), then vadimcn and klutzy are the people to talk to. (IRC handles match their GitHub names.)
It's as simple as, something that's concurrent (simultaneous) may not be parallel (physically) but if it's parallel it's also concurrent. When used as a verb, parallel is interchangeable with concurrent.
Being in the military he has no private life; he's in violation of the UCMJ. Also, because of his rank and position there are security issues.
But I'm guessing the real reason for the investigation is that he pissed the wrong person off, or it probably would have been swept under the rug, so to speak.
