    Youtube - more idiocy
    • The showinfo parameter, which indicates whether the player should display information like the video title and uploader before the video starts playing, is also being deprecated. Following the change, the channel avatar and video title will always display before playback begins, when playback is paused, and when playback ends. The avatar being displayed is new behavior that will be consistent across all embedded players.

      I like as idiots begin to rule as they want.

      No one is at fault that some Google developers just do not have anything else to do.

    PV Lab: New strange kid on the block - Spectrum Similarity Index
    • The Spectral Similarity Index, or SSI, addresses problems with existing indices, such as CRI, that have become evident with the emergence of solid-state lighting (SSL) sources such as LED’s.

      In contrast to the relatively smooth, continuous spectral power distributions of blackbody emission, tungsten incandescence, and daylight (and the ISO standardizations of these sources), many solid-state sources are characterized by peaky, discontinuous, or narrow-band spectral distributions.

      Well, solid state, aka led sources are exactly much better than fluos or such. They are smooth, except some blue peak.

      These spectral distributions can wreak havoc with color rendition (by both film and digital sensors), since film and digital cameras are all expressly designed to work with, and are indeed optimized for, standard tungsten and daylight. This problem is exacerbated by the fact that CRI, for example, is based on human color sensitivity rather than camera sensitivities, and is determined by the rendering of a small number of test colors, which are mostly of low saturation and do not include skin tones. The TLCI measures rendering by an idealized three-chip camera, which does not adequately account for the differing spectral sensitivities of single-chip cinema- or still-camera digital sensors.

      Well, make it account, but in reality of design ARRI cameras, for example, have sensitivity quite close to human vision. We have topic.

      For these reasons, SSI is not based on human vision, or any particular real or idealized camera, and does not assume particular spectral sensitivities. Rather, it measures how close a given spectrum is to a specified reference spectrum, such as tungsten or daylight. It is a single value representing the quality of the curve fit to the reference spectrum, and indicates the predictability of color rendering with the given source. SSI is scaled so that a score of 100 indicates a spectral match; high values indicate predictable rendering by most cameras (as well as “quality” of visual appearance). Low values may produce good colors with a particular camera but not with others. SSI is useful for cinematography, television, still photography, and human vision.

      Sounds real nuts, yes, exact curve matching with black body spectrum warranty good colors. But it is not requirement, exactly due sensitivity curves and human perception.

    Capitalism: Facebook now has outpost to block anything they don't like
    • image

      Facebook on Wednesday briefed reporters on its latest efforts to uncover nefarious uses of the platform during election season, offering a tour of the large conference room where dozens of employees are monitoring events around the clock.

      Employees use CrowdTangle, a company acquired by Facebook that monitors the viral spread of articles across platforms, to detect which articles are trending on Facebook, Instagram, Twitter, and Reddit.

      All told, representatives from 20 teams have people in the war room, representing 20,000 global employees working on safety and security.

      Safety and security of ruling class. :-) Sad to see all this servants as their role is similar servants played during late Louis XVI .

    Sony wants to go green toward banckrupcy
    • Just a month after Sony announced its plans to power its worldwide operations with 100 percent renewable energy by 2040, the tech company has brought forward its US goal by a decade, to 2030. Sony currently sources just 25 percent of its energy in the US from renewable sources, so the decision represents an ambitious vision for the RE100 company.

      I like this idiots. To this time it can be exactly few office spaces with managers left and some designers rooms. This guys could live even on energy of their farts.
