Metadata included in the HDR container tells the TV how to render an image, including how bright to get....

Lenses aren’t just dumb tubes that you attach to your camera; they manipulate light in complex ways. One of the side affects of this is optical distortion. Let’s look at it in more detail.

What Does FPGA Mean? FPGA stands for field-programmable gate array, a type of integrated circuit that can be reconfigured after manufacture. Unlike a traditional computer chip, FPGAs use programmable logic blocks and interconnects that can be reconfigured to suit a variety of different purposes. In essence, an FPGA can be reprogrammed to act as any type of digital circuit. This can be done over and over again simply by loading a new configuration into RAM to emulate a different type of chip....

The answer presents a fascinating look at the history of video games. When people talk about how hard old video games were, they use the phrase “Nintendo Hard.” Nintendo wasn’t the only company making early video game consoles (and certainly not the first in the market)....

Improvements Made in the Apple Watch Series 8 The Apple Watch Series 8 only has very few new features to separate it from last year’s Series 7 (which was only a few steps removed from the Series 6). Apple again focuses on iterative improvements, making small tweaks rather than large overhauls. As a result, the Series 8 looks identical to the Series 7 that came before it. The main visual difference concerns case materials since the Series 8 is not available in a titanium finish with Apple instead settling on stainless steel and aluminum....
