> Modern SDD have read limits. Every 10.000 reads or so the data has to be refreshed. The firmware will do this silent.

Please provide reference(s). I have never seen any indication of this, or at least there is no read limit for the flash memory itself. You can read from it indefinitely just like static RAM, without "refresh" as required for DRAM.

Here we go again (same discusion on Slashdot several years ago). Everyone can see 24 Hz. flicker. I seriously doubt there is anyone on earth that cannot. This problem was solved long, long ago by flashing each movie frame on the screen 2 or 3 times, then switching to the next frame. 3 x 24fps = 72 Hz. This corresponds perfectly to the fact that, for most people, a CRT refresh rate of 72 Hz. or so is comfortable. For example, the Eumig S710D Super 8mm film projector from the 1970s has a 72Hz. refresh rate due to its triple-slotted shutter.

Passage of these bills effectively bans drones and video camera guided RC (Radio Control) aircraft because cameras are used for navigation, not just taking photos of objects of interest.

Useful applications of privately-operated drones and RC aircraft with cameras include roof inspection and birds-eye view promotional shots for real-estate listings.

Making these devices illegal will cause more harm than good.

My first computer experience (1972) was at 110 baud, banging away
on an ASR-33 Teletype connected via leased line to a DEC PDP-8 running Dartmouth Basic.

I'd get up and run a lap around the building for fresh air while printing
a program listing. Data rate in/out was 10 CPS (Characters Per Second).

I recall proudly showing my dad the program listing at home, unrolled on the living room floor at about 10 or 12 feet long...

Reliance on tools of this nature will reduce the quality and clarity of the source code. The programmer will have little motivation to use descriptive variable names or constant definitions.

This is evident in the video. You can see the use of integer literals everywhere instead of symbolic constants.

How about writing up a tutorial on how to correctly declare
c/c++ numeric variables. When I went to school many moons
ago, int and long were it.

http://www.cplusplus.com/doc/tutorial/variables/

has a tutorial on declaring variables, and a table listing sizes.
They state the sizes of char, short int, int, long, etc.

If this is not the correct way to do it, please help enlighten us!
Thank you.

32GB in less than 2 minutes?
pure BS
32GB = 32*1024*1024*1024
                  = 34,359,738,368 bytes
lets round down to 30,000,000,000 for simplicity
30,000,000,000bytes / 120seconds = 250,000,000 bytes/second
So, tell us which USB or Firewire card reader can read at better than 250MB per second, and which brands and models of SD cards support reading at that speed?

If the turned-off LED power supplies were still consuming power, that power would have to be dissipated in a load of some sort, and a heat sink would be required to get rid of the heat generated.

Unless the LED lamp contains a ballast resistor as a load dumping device, this is very unlikely, unless the LED lamp is of especially crude design.

The 120 VAC LED lamps I have certainly don't have this problem.
