I guess the #USB - #UVC driver for #Linux needs an update...

So it's 16KB transfers and I guess 512 byte packets and... https://github.com/torvalds/linux/blob/8f0b4cce4481fb22653697cced8d0d04027cb1e8/drivers/media/usb/uvc/uvcvideo.h#L55 Hardcoded 32-packet limit. Of course, this has not been increased since the driver was written in 2008... when webcams were 480p30. Aaaaaaaaaaaaaaaaaaaaaaa

#UVC light kills nearly everything—except this unusual organism
#UV-C is such a killer, in fact, that scientists have questioned whether life can survive on worlds that lack an ozone layer, such as #Mars or distant #exoplanets. Research suggests one hardy #lichen, a hybrid organism made of #algae and #fungi, may have cracked the UV-C code with a built-in #sunscreen, despite never experiencing these rays in its long evolutionary history.

… "HDMI capture #UVC" (#USBVideoCapture) https://www.bhphotovideo.com/c/search?q=hdmi%20capture%20uvc&sts=ma seems better search term than "external HDMI capture USB"

Needed to reread one of the reviews (of Roland UVC-01 USB Video Capture, UVC-01, 1080p60, US$ 218) to parse "AI" in the context as "audio input" https://www.bhphotovideo.com/c/product/1633695-REG/roland_uvc_01_usb_video_capture.html/reviews

Ooh, VGA input!
AVMATRIX Multi-Signal to USB 3.0 Capture, UC7018, $ 430, https://www.bhphotovideo.com/c/product/1891091-REG/avmatrix_uc7018_multi_signal_to_usb_3_0.html
—‍ reported bad support in reviews of other items sucked the excitement.

⚠️ Pandemic preparedness: Far-UVC lamps offer continuous, safe airborne virus control 💡🦠

Recent research shows 222 nm far-UVC light can:
💥 Inactivate flu and coronavirus particles mid-air
🔬 Penetrate pathogens but not human cells
🏥 Enable safe, continuous disinfection in occupied spaces
🚀 Potential to reduce transmission in schools, hospitals, airports

Integrating far-UVC into building systems could transform our approach to airborne disease prevention. What’s your take on rolling this out at scale?

Stopping the next pandemic could be as simple as switching on a light bulb

Solid state far-UVC lamps could be a huge deal.
