Your first paragraph is advocating for ventilation, which is great but there's been so much incentive to reduce building energy consumption (heating/cooling) that recirculating, filtration and other technologies have resulted in offices becoming almost sealed off. We are now moving towards more balanced models as people don't feel comfortable in such offices e.g. sick building syndrome.

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 to room as has been shown during the pandemic in elderly care facilities. That would be the only use-case I see.

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 complexity of UV lights (deterioration, energy consumption, replacement).

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 at 4kV. I don't really see this here, so it makes me doubt these devices.

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 comments below, any "UV" is considered dangerous by people not aware of the biological effects of various wavelenghts.

Besides this, excimer lamps have a low expected lifetime, of both the light source as well as the filter due to the high energy in the UV photons. This makes replacement (and maintenance cost) a real risk. This could be remedied by similar wavelength LEDs from companies like CrystalIS but these are expensive and very low power (only work germicidal on a short distance).

Prof. Brenner at Columbia University has first foreseen applications of 222nm in operating rooms, to prevent infection during surgery.

On the whole, it would need significant investment in both research, certification and risk analysis for this to become commercially viable, so while some of the technology is there, the market demand so far just is not -- post-pandemic.

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 French...

China, Japan and USA all have their chip machines, just ASML is making the most advanced ones.

My experience with Aliexpress USB CD drives is they contain recycled laptop optical drives, sometimes over a decade old!

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 (lack of MMU), Sheepshaver has some weird incompatibilities, for instance MS Office, that you won't encounter running Qemu. On Mac, the UTM app is a great place to start!

Even having a few 'retro' systems up and running, mostly Macs from the early 2000s, I find that what we used to do on them: chatting on Skype or MSN Messenger, listening to shoutcast streams or downloading on Napster, playing Unreal Tournament online etc. are mostly defunct now. What remains are local games, clunky word processors and MP3's on the local network. It turns out to be a largely empty experience unless you really get back into Command and Conquer or Metroid.

I hate to suggest it but it’s extensively explored by Graham Hancock when discussing the Americas in season 2 of Ancient Apocalypse.

Even dismissing his ideas around an older civilization wiped away by a “younger dryas event”, the archeological findings in the Amazon were new to me.

Would there be a market for USB-C plugin "ai accelerator" hardware? Running something like a neural net chip the likes of Axelera, Hailo?

Saving you a Wikipedia search: “ Foods that have high amounts of isoleucine include eggs, soy protein, seaweed, turkey, chicken, lamb, cheese, and fish.”

Having just read the Matthew Perry memoir, this one fits perfectly too.

Commercial real estate is under huge pressure and seems to have hired major PR firms to turn the tide...

I was surprised to learn it is the most capable emulator for SGI machines: https://sgi.neocities.org/

I guess the hardware is similar enough.

For me it would be https://en.wikipedia.org/wiki/Quetzalcoatl

Is this the Lindows - Linspire lineage or something else?

Sounds amazing from the description but I struggle to find a video showing it in action?

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 Shanghai company Espressif.

Spoiler alert for Season 3 ;-)
