This is nothing new, just the latest rehashing of the same rumor that's been recirculating for months.


yeah, I was looking for something more than a single analyst's note here.


Kuo has an excellent track record on Apple predictions from what I understand.


Who is him anyway? I’ve never been able to trace that.


Thats a great side effect when dealing with being exposed to the virus, but I think health professionals would not recommend this instead of a vaccine.

>The three types of UV radiation are classified according to their wavelength. They differ in their biological activity and the extent to which they can penetrate the skin. The shorter the wavelength, the more harmful the UV radiation. However, shorter wavelength UV radiation is less able to penetrate the skin.

>Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.

>Medium-wavelength UVB is very biologically active but cannot penetrate beyond the superficial skin layers. It is responsible for delayed tanning and burning; in addition to these short-term effects it enhances skin ageing and significantly promotes the development of skin cancer. Most solar UVB is filtered by the atmosphere.

I think this is a misunderstanding.

It won't penetrate deep into the skin, it will continuously cook the top layers.

Frequent exposure WILL cause damage to skin and eyes.

Creating and selling personal protective equipment should be taken very seriously.

Putting UVC light sources on a headband without controlling airflow is simply too risky, no one could safely guarantee that a stray air current and or virus from an unexpected angle would be exposed to enough light for enough time to be safe. Air flow must be controlled.

This report seems to say that that is not true for 222nm https://journals.plos.org/plosone/article?id=10.1371/journal...


Glad I was wrong! Hopefully this can be certified and implemented in all kinds of sterilization devices ASAP.

Thank you for the link.


A maker's implementation: https://www.youtube.com/watch?v=fzGrh2io9Ds&

Looks cool, not sure how well it works.


That mask uses UVA which doesn't kill germs. Only the horrifyingly dangerous UVC kills germs. Don't even think about making a DIY UVC device. You could blind yourself in seconds.

the 15" macbook pro has a dedicated gpu, the mac mini only has integrated gpu.


All of long island has 7.5 million people, at 5,617 people per square mile.

The bay area average is 868 people/sq mile.

No, the bay area is not dense at all.


There are different kinds of homeless people.

Some of them might do well in such a setting.

But more than a few of them would be disruptive and ruin the land and ruin it for everyone else.

There are plenty of articles and videos about what ends up happening to these encampments- they turn into dumps with piles of used needles and lots of human waste. The last thing you'd want is something catching fire and spreading.

Generally, most habitable 'live off the land' type of places are spoken for already, no nearby property owners are going to approve of such a 'zone'.


i think they're in some odd holding pattern on their downward spiral, where there isn't enough capital for changing the business or even purchasing new product, but there isn't enough business potential for new investment either.

perhaps they are keeping everything open as shells to try and shop some deal to potential investors as revitalizing a once great brand.

someone up high has some really good and specific reasons for keeping most of the stores barely open and operational.

if there were responsible people at the helm they would shutter nearly all the locations immediately.

they probably have a few dozen months of funding left at this pace, no idea what they're holding out for, they seem to be just delaying the inevitable.


What do you mean not possible to reinstall the OS?

They don't make it easy, but you can download older OSX images from apple's servers (Sierra, Yosemite, etc..) and install them with some effort.

Not impossible.


This submission might as well be a 'bump' for the discussion thread referenced in it:
