+ - Traffic lights: There's a better way

Submitted by stephendavion
stephendavion (2872091) writes "MIT researchers develop an improved system for timing of urban lights to minimize commuting times. Anyone who has ever driven a city street and been frustrated by having to stop again and again for red lights has probably thought that there must be a better way. Now, researchers at MIT have developed a means of computing optimal timings for city stoplights that can significantly reduce drivers’ average travel times.

Existing software for timing traffic signals has several limitations, says Carolina Osorio, an assistant professor of civil and environmental engineering at MIT. She is lead author of a forthcoming paper in the journal Transportation Science that describes the new system, based on a study of traffic in Lausanne, Switzerland."

I have gambled many times many ways and it is nowhere near as addictive as gaming is. i have played video games since i was 5 i think, i am currently 36. in my 31 years as a gaming addict there never was enough time to game... oh i learned a few other hobbies but gaming was always the excuse for someone to get me to read or do other acts besides the gaming. portable gaming just made the problem worse, and i started to have money -- to rent games. so i rented. my grades in school suffered because i always had to have that gaming fix. when i skimmed through school and finally got a job, i used that income to you guessed it game. i had 14 credit cards and an inability to hold down a job -- because it interfered with my gaming. had i hit rock bottom? nope i got a bankruptcy and eliminated all my debt all $35,000 of it and with nothing to show for it, because i lived off cash advances when i couldn't hold down jobs just to keep all the bills paid. and that wasn't rock bottom not yet. i had had problem in years past with starcraft, and broke, living with my parents i found the sequel to a game i had played years ago, the old game being warcraft II. warcraft III was way more addictive and when it's expansion came out i played it for a long time warcraft III The frozen throne is a game i literally played 8,000 ladder matched games plus countless thousands of non ladder games such as DOTA. this was rock bottom for me. i would play a good 14-16 hours a day into just one game i read this website and other while waiting for matches or when i felt the game was lost and stopped trying. i was having issues sleeping at night and i wasn't on any drugs not even caffeine since i had no funding to pay for it. i basically cracked and developed PTSD but it went unnoticed and i finally got help i needed, for other issues that were not related to the gaming but perhaps were increased by it. i had to quit games cold turkey as in hospitals it is very hard to game seriously because everything with a cord is prohibited and i only saw people using handheld games, like a hand held poker game, for example. nothing even as close to as addictive as the warcraft 3 game. tbh i even occasionally play games but i set pretty strict rules about when and how much i can game. fortunately i like to read and watch movies, and it no longer is 'instead of gaming' but rather because i don't dare game more than a few times a day (currently playing League of Legends a dota clone, which was spawned from warcraft to keep up micro skills of ladder players.) it is a free to play game, and is slightly easier to play than regular warcraft 3 tft. but even with all this addiction i never bought in game items (and there are plenty of them to buy) though i can see how people can be addicted to that like gambling. the adrenaline rush of playing a game is way more addictive than drugs or money, because there are ways to find cheaper fixes that are just as addictive. money is nice don't get me wrong, and yes chemicals can make you feel good but, dude an AAA video game is $60 a computer to play it starts around $400, for decent parts, my personal rig cost me $1100 in parts, including os cost, and it plays everything out there. how much heroin can $1,200 buy you? whereas between renting and internet research finding the game that addicts you most can take you down a long and windy road that only requires a little bit of electricity compared to drug costs to get the same effect.

I agree. It sounds like the most useless concept I've ever heard of.

The only good thing about so-called "smart" watches is that they don't have cameras like Glassholes wear that you need to worry about in public.

I foresee a resounding "thud" from the sales volume on these devices.

But then again, I use a desktop computer and a laptop, and have absolutely no touch devices, portable or otherwise. I wouldn't mind one of the newer Samsung android tablets with high resolution video and a stylus, but it's so far down my list of "would like to purchase" that I expect Android itself to be obsolete by the time there would be money available for one. :P

Journal: 24/192 Audio Redux

Journal by msobkow

A while back I put my laptop into forced 24bit/192kHz output mode in order to be able to play some Grateful Dead tracks that were recorded in that format. I've left it at that setting on the Windows 7 laptop because it plays back lower resolution audio just fine.

Comment: Can I have an indigo pixel? (Score 1) 117

One possibility would be improving the color range, even if the resolution isn't improved. Rather than cramming in three phosophors per pixel, perhaps we could have four, or more. There's a considerable chunk of color space not well represented by RGB color.

I don't know how much of a difference it would make to TV viewers or gamers, but I know that artists would be grateful for a better color range. The conversion from RGB to CMYK is always a bit of a crapshoot; things that look great on your screen don't look as good when they come back from the printers, and there's a whole range of stuff it doesn't occur to you to try because you can't see it.

I could even imagine that it might be handy for medical imaging and other applications where you want to cram as much information onto the screen as possible: more pixels may not improve things but more colors might. Though more pixels could achieve that as well: it would be nice to be able to zoom in by bringing your face closer to the screen without simply seeing bigger pixels. Head motion is kinaesthetically appealing: you can move in and out without losing your sense of overall place.

Sharp already makes a four-pixel TV, with an added yellow (which is especially helpful in skin tones). I think it would be neat to be able to produce true indigo, violent, and cyan. If this lets you add more phosphors without costing resolution, it might not be a killer app, but it could be a desirable thing.

I am intrigued by your ideas, and would like to subscribe to your newsletter.

I think that the combo tent/backpack/hammock would be a challenge, since each has different materials for different purposes. But the weight savings (or comfort from not doing without) could be substantial (at least, in an activity where people are said to snap handles off toothbrushes to save weight), and now that you mention it I'm surprised that somebody hasn't tried before. If I actually see the product on shelves some day I'll raise a glass to ya.

In that case, France would charge an import tax.

But what really happens is the book is printed in Germany, sold to Amazon in Luxembourg, sold to someone in France, and all the profit funneled through Netherlands and/or Ireland, where is somehow becomes no profit and hence no tax due.

Hereditary=genetics? What kind of a gross over-simplification is that? "Like in Humans, Genes Drive Half of Chimp Intelligence"? Genes don't drive human intelligence. They determine the upper and lower limits that can be achieved with proper nutrition, care and education and a multitude of other factors. More and more factors are being discovered everyday, each diminishing the role of genetics.
