These 'trivial' changes often cause merge conflicts with other trees. If people are developing against the 'pre change' tree, any changes around the comments might need manual merging. Manual merging introduces additional opportunities for mistakes. I see trivial comment patches like this bounced on these exact grounds in watching active linux driver changes; particularly if you watch a new vendor driver submitted to the staging tree, and then watch it get cleaned up to be in-line with the kernel's coding style.

As far as this PARTICULAR patch being dropped, it probably could have been handled more in line with 'NACK: We'll set a date in the future to do a comment cleaning and have everyone rebase on that', but my first reaction isn't that the developer who declined it is sexist (or whatever the particular flavor of discrimination is). From my PERSONAL Point of view, a change should provide value, and I *PERSONALLY* don't see value in a change like this. A typo fix maybe, but this is not a typo.

Well, I missed my 10 year journal anniversary. Maybe I'll catch the 20th anniversary.

Does anyone every read these?

The reason I've always heard is pure cost to convert. All the signs, all the cars, everything that uses distances (all the laws would have to be 'amended' to the new units), etc, etc. There is a LOT of infrastructure in the US. It's a physically large country. Even 'phasing' it in is a HUGE undertaking and would take years if not decades to complete.

I am 100% in support of us converting, but I'm glad I don't have to be one of the people that's going to coordinate the madhouse it's going to be when it's finally decided upon and started.

the difference is, it doesn't take the same energy. In the kinetic energy equation, look at the V^2 term. If you start at velocity X, and increase your speed A, your resultant velocity component will be (X + A)^2. Multiplying that out, you get X^2 +2AX + A^2. To go from 0 to 10 mph, you have to add 2 * 10 * 0 + 10 ^ 2 = 100 units (I don't remember the American unit applicable here). To go from 90 to 100, you have to add 2 * 10 * 90 + 10 ^ 2 = 1900 energy units. It takes 19x as much energy to increase speed 10 mph at 90mph IGNORING DRAG.

The X^2 gets ignored because we're only considering the amount of energy we have to ADD to go from X to X + A, and the KE at Vx will end up canceling out the X^2 in the resulting equation subtractions.

Sure backscatter has been done... But it always used known frequencies as the signal source. This will pick up any ambient ref noise and use it to generate a new signal.

Essentially, you could embed a transmitter anywhere without concern for a power source (assuming there are other transmitters around).

Same happened to me :-/ I created an account in either late 98 or early 99 (too much happened in the last dozen years to be sure), forgot what my login/pwd were, so I recreated this one with my massive UID. It was still fun at the anniversary party to have a 'low uid' though. Lots of 7 digit UIDs in the Ann Arbor area.
