Studying a building's microbiome is really a new field. What happens to people if offices become boxes of sterile air and -surfaces? We don't know.

You are correct, however most of the harmful rays get filtered out in the upper atmosphere. Far-UV doesn't reach Earth, only UV-A and small amounts of UV-B (if the ozone layer is more or less intact that is!).

The germicidal effect is a function of the DNA being directly affected by the UV rays and breaking apart. Very few organisms exist that could adapt, this would require external shells, skin etc, not typically found in microorganisms.

Could accumulate in an isolated room, but following normal building ventilation standards, really shouldn't be an issue as shown by Brenner in 2023: https://pubmed.ncbi.nlm.nih.gov/38037431/

The mould reduction is real, and could lenghten the maintenance intervals for cleaning. Not fully eliminate it though, it really only eliminates the parts the UV light reaches (so not the back, or any other part not exposed).

Mostly used to eliminate or reduce mould growth on the inverter? If HVAC is taking air in or blowing air out, there really wouldn't be a point disinfecting the air. If it's re-circulating, it could reduce the spread of germs room

This is correct and such systems do exist, sometimes combined with sources of ions and HEPA filters. However if you're already drawing air out of the room, it's easier to just filter it with HEPA than dealing with the additional c

Still risky, these typical Chinese devices don't come with a filter, so harmful wavelengths will still be present. The filter is actually the expensive part. Also, such a small component would need sufficient cooling as these operate a

I have worked on such systems at Signify: There are numerous barriers to wider adoption except for very high risk situations. For instance: there have yet to be lawsuits to determine the risk of exposing people to UV. As you see in the comm

Over time, the value proposition of Apple devices in the EU will be less, and less differentiated vs competition, which will make them either lose their premium appeal or market share (or both). In the long run, Apple will likely reconsider

What always surprises me is the sheer amount of fake, scammy, apps trying to appear as if they're something else. Trying to steal clicks from users looking for Adblock, VLC or other legitimate apps... it's a mess!

ASML is not an american tech company known to throw billions around. It appears they do see the value of LLM-based AI but are not comfortable working with either US or China based suppliers. Also, don't disregard that their new CEO is

Sheepshaver is great, but I've found Qemu's PPC emulation has progressed probably beyond what Sheepshaver can offer. For instance, it can run MacOS 9.2.2 and even early MacOSX PPC versions. Due to it's emulation limitations (

To me it seems that Risc-V is China's 'plan-B', their systems are the first to use it and SBC's do exist already in China. I've even seen IoT cores from Chinese vendors moving to Risc-V, like the popular ESP32 from

Apple has been providing security updates for iOS 14, but so far no 14.8.2, strange since all other supported OS-es were updated today. Often the samen CVE’s get fixed in macOS, iOS, tvOS etc together. They are pushing iOS 15.2 though. I wo
