This is a troll, right?

There are legislative bodies at both a federal (House of Representatives and Senate), State (same except in Nebraska) and local levels, with varying terms of office (typically 2 years for house, longer 4-6 years for Senate). State and local executive bodies, sometimes local judges, various other executive branch positions at the state and local level. And ballot initiatives.

So I'm voting for congress (house), state assembly (lower branch of state legislature), County supervisor, Water district board and 6 state wide and a couple of county wide initiatives tomorrow.

I did phone banking to get out the vote for a few senate races that look to be key ones for the 2015-2016 US Congress.

Seasons are defined by the length of diurnal periods and the direction of the change:
Winter - Daylight period is increasing, lower than night period (lowest amount of daylight)
Spring - equal diurnal periods, daylight increasing
Summer - Daylight period is decreasing (greatest amount of daylight)
Autumn - equal periods, daylight decreasing

PLATO was born in 1960. By 1973 it had grown to the point that it enabled social networking of sorts - online games as well as its ostensible purpose for computer aided instruction.

I remember PLATO terminals in the university library when I was first using computers - they were big amber plasma screens that did pretty good graphics for the time. Beat punched cards and green bar paper as far as user interface hands down. It was a lot nicer than the dumb terminals that were starting to be available for coding.

Some of us don't live in the UK.

Laws governing city charters vary according by state (both nation state - eg US, Lithuania, and subdivision state, eg Vermont, California, Jalisco, Aguascalientes).

In the US the name "city" also has a federal meaning - Standard Metropolitan Statistical Areas as defined by the Census typically are called cities by their inhabitants regardless of their legal status.


Bike Projector Makes Lane For Rider 856

hh4m writes "Whether it's San Francisco, New York, or any bicyclistic city in between, you're destined to witness biker after biker dancing with danger, especially at night when visibility is uncomfortably low. Alex Tee and Evan Gant's LightLane device was recently just a concept but is soon to enter reality as a much-needed visual declaration of personal biking space. With a dire shortage of dedicated lanes, LightLane provides urban cyclists with a solution that adapts to them and any route they make take. The compact projector mounts easily to the rear of a bike frame and projects a bike lane-inspired linear pattern that provides great visibility and a familiarity that helps catch a driver's attention."

It actually has gone back in forth between specialized graphics systems and graphics done via special purpose hardware. Sutherland observed on this and called it the Cycle of Reincarnation"

Great "chip technology"? Um, cpus and gpus are both chips, ad general purpose computing does get done on gpus, see CUDA for example. Reminds me of the move to vector systems in the 90s although that used multiple cpu/fpu units on boards rather than single chips.

The degree of technical confidence is inversely proportional to the level of management.
