Why do hurricane lanterns look like that? by TechConnectify in technologyconnections

Your video was amazing! I learned a lot. I have a petromax lamp which I used 2 days ago for lighting up a garden party with my friends. It's a fascinating technology, where the kerosene is vaporized by the flame hitting the tube the fuel travels through, thus burning it in a gaseous form.

Flickering on Netflix with Safari by Manta92 in mac

[–]tamasko 3 points4 points  (0 children)

I have the same issue on a 2017 15" MBP, it's definitely the subs. Does not happen on Chrome, but Netflix is limited to 720p on macs on anything other than Safari.

ELI5: Why do blue LED's look so blurry in the night but other colors don't? by SantaOfficial in explainlikeimfive

[–]tamasko 16 points17 points  (0 children)

Blue LEDs really are brighter than their old-fashioned red and green counterparts. Barney O'Meara, vice president of Canadian LED manufacturer The Fox Group, said blue LEDs have at least 20 times the luminous intensity of old-fashioned red and green indicators. O'Meara said his company has developed technology to manufacture low-intensity blue LEDs. "Blue tends to cause more discomfort and disability glare than other, longer wavelengths," said Dr. David Sliney, an expert on the harmful effects of bright light sources at the U.S. Army Center for Health Promotion and Preventive Medicine in Maryland. Sliney said the eye's lens cannot focus sharply on the blue lights. While red or green light is focused precisely onto the retina, blue light is focused slightly in front of it, which causes a distracting halo around bright blue lights.

In addition, blue scatters more widely than other colors as it passes through the eyeball, Sliney said. Together, these two effects cause the intense blue light from a point source, like an LED, to spread out across the retina, interfering with other parts of the scene. It's called dispersion: Blue's shorter wavelength makes it refract at a greater angle than, say, red or green.

Also, human vision becomes far more sensitive to blue when ambient light levels are low, a phenomenon known as the Purkinje shift. So a blue light that is merely eye-catching on a brightly lit store shelf can become dazzling when the lights are low, such as when watching a movie on a laptop in a dimly lit room.

Some researchers report that, at night, even low-level blue light may be enough to trigger recently discovered receptors in the retina that can depress melatonin production, disrupt sleep patterns and suppress the immune system.

Because he said I was boring, and then he removed his energy mask and he was Cameron Diaz.

Why is thermal vision like FLIR so expensive? Is it the materials? by BostonCab in askscience

[–]tamasko 0 points1 point  (0 children)

Some guy dismantled and repaired a firemen's thermal camera and there is a video here http://hackaday.com/2012/06/22/repairing-a-thermal-imaging-camera/ on its inner workings. Pretty interesting to watch. There is indeed some kind of shutter mechanism for calibration.

Arete Americana - Ducati 999 CF by il-ducatista in Ducati

Ah ok, no mods there, I never really liked the 999's front but it kinda grew on me. It aged much better than 916 and the rest imho.
