They must be engaged with a enemy with which we are at war as declared by Congress
So that would be no one since WWII?
...they can recognize hundreds of molecules, and subtitles of radio spectra...
What are the radio spectra subtitles saying? Are they in Japanese?
Wait, if they're already blasting it full on, why are they using PWM at all?
I was going to use a TLC5940...
There's part of your answer - they use PWM controllers because they can be controlled via a serial interface and they don't require a resistor per segment. The actual PWM part is a bonus. You've seen the 'throbby' turn signals, right?
A cap would work, but they're notoriously unreliable in high heat/extreme conditions, they're expensive, bulky, and it would have to be a fairly large cap to provide a slow enough rise time at typical LED currents. The other downside is that the cap would likely also result in an equally long fall time. Depending on the circuit (assuming no constant-current source) the inrush currents could be fairly high (a discharged cap is like a short circuit until it charges).
A better solution would be to modify the existing PWM code (as the parent poster mentions) to ramp the brightness up instead of blasting it full-on. This is done in switching supplies to provide what's called 'soft start'. Here's an example using a Microchip embedded processor.
Not to mention, traffic lights.
Maybe it's just my old eyes, but I find the wicked-fast 'rise time' of LEDs in traffic lights and auto stoplights startling. To me it's actually a distraction to be startled every time someone hits their brakes. I'll probably get used to it as they become more prevalent.
I have a pic somewhere of the Virginia equivalent - the car was parked outside my office.
What about the HAM radio guys who put their callsigns on their plates? Oh noes, they have a hobby and used a plate instead of a less readable bumper sticker. What a sense of entitlement they must have.
At least in Virginia you must have an amateur radio license (duh) and amateur radio equipment installed in your car to qualify for a ham plate. The rationale is that if a police officer needs comms, they can rely on anyone with a ham plate. After all, the first purpose of amateur radio existing (as codified in Title 47, Part 97.1a):
"Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service, particularly with respect to providing emergency communications. "
Are you familiar with the works of H.R. Giger? I just got a mental image of a a cow with a steampunk-esque tank on its back, contentedly munching on grass.
I think the majority of the problems were due to a bad batch. I ordered 5 last November and 3 were DOA (USB/network issues). The 3 Newark sent as replacements were good; good enough to play 1080p video streamed over the LAN with raspbmc and not reboot yet (months and counting).
According to Wikipedia, the US interest in bioweapons started around 1918.
An interesting coincidence given that the world has just been subjected to the deadliest viral pandemic in history, no?
It killed between 50 and 100 million people - 3% to 6% of the world's population at that time.
If that happened today, it would kill the equivalent of every living soul in the United States and Mexico. Sobering, huh?

I made the Darth Vader comment - it's from the air leaving the little exit hole on the mask. Trying to talk with the CPAP on makes you sound more like Zuul (at 00:13), not Vader.
Re: the fan ramp-up sound - I think what you might be hearing is the fan returning to normal speed after slowing when you exhale. All of the CPAPs I've used with that option have a setting to turn that off. I prefer no initial pressure ramp-up and no pressure release when I exhale (it makes the mask stay in place better).
If the noise still bothers you, you can try putting the machine on the floor or under the bed. You can also use those foam in-ear earplugs.
I'll agree with most of what you say as long as you don't try to take away my intelligent, tasty bacon.
