Vortex is continuing to roll out new optics, and the latest is the Venom Enclosed Micro Red Dot. The post First Look: Vortex Venom Enclosed Micro Red Dot appeared first on Gun Digest.| Gun Digest
Normally, the focus of gear-related articles here is whether they are geared for duty use. I try to look at gear in that light – especially thinking back to when I started in the profession. However, back then, we were not inundated with the amount of technology and advertising you all are hit with today.

One of the most poorly-defined yet critical things in configuring a VR avatar is where exactly to place the viewpoint. It can have a lot of impact on your viewing experience, especially with how the viewpoint ends up relating to the rest of the body. This becomes especially critical in systems like VRChat and Resonite where the physics of the body are directly impacted by this placement, and especially now that VRChat has built-in functionality for allowing a first-person view of your facial ...| beesbuzz.biz

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s).| New Atlas
Researchers in Japan have clocked a new speed record for data transmission – a blistering 1.02 petabits per second (Pb/s). Better yet, the breakthrough was achieved using optical fiber cables that should be compatible with existing infrastructure.| New Atlas
