I see you also choose to ignore facts when presented. The URL above by nih prior to Covid shows the size particles and efficacy. Covid is 40x smaller than an N95 can filter.

And cloth and N95 masks increased the aerosol disbursement of Covid with every exhalation.
The problem is even at 95% efficiency against 5 micron particles, the corona virus is 40 times smaller. And the 30% it MIGHT catch just becomes an aerosol as soon as your exhalation decreases the humidity enough to allow the 1/40th size particle to pass through.
So what part of âoecovid is already way smaller than any cloth or N95 mask can filterâ do you not understand?
So lets say for a moment, a cloth mask stopped 100% of all exhaled virus on the first exhalation.
How many more breath before your exhaled breath dehydrates the first droplets and blasts them out into the atmosphere as an aerosol?
1? 2? 5? And then every exhale after that expels more. and more. and more. And the warm moist breeding ground that is collecting that aersol is repeatedly rejeuvenated with each following exhalation.
Wrong.
"N95" refers to a class of respirator filter that removes at least 95% of very small (0.3 micron) particles from the air. Some people have mistakenly claimed that since the virus that causes COVID-19 is approximately 0.1 microns in size, wearing an N95 respirator will not protect against such a small virus.
You convinced yourself that wearing a mask prevents the spread. Until the spittle + covid becomes an aerosol from dehydration and continues on its merry way, only now it has a warm, moist breeding ground that you continue to aerosol from on every exhalation, spreading the virus as you move about freely in your gleeful ignorance.Congratulations! You are now a super spreader.
so what "impingement" held the moisture trapped virus particulates to the cloth on the next exhalation? Or the next? Or the next. Eventually, the dehydration occurs and the aersol spread of covid continues.
So droplets embed on a surface that allows air to passthrough as well as virus cells and material far in excess of the size of a covid virus.
Now, answer this question:
Q: What happens when you pass air through a material that allows air and material far larger than the corona virus to pass through?
A: It becomes an aerosol, spreading up to 20M from the source. It ASSISTS SPREADING.
Masks, especially cloth masks, did NOTHING to prevent the spread of covid.
Upon analysis of negative-stained SARS-CoV-2 articles by electron microscopy, different researchers have had varying results, but the diameter of the virus has been found to range between 50 nm to 140 nm.

Inexpensive cloth masks are widely used in developing countries to protect from particulate pollution albeit limited data on their efficacy exists. This study examined the efficiency of four types of masks (three types of cloth masks and one type of surgical mask) commonly worn in the developing world. Five monodispersed aerosol sphere size (30, 100, and 500 nm, and 1 and 2.5 m) and diluted whole diesel exhaust was used to assess facemask performance. Among the three cloth mask types, a cloth mask with an exhaust valve performed best with filtration efficiency of 80-90% for the measured polystyrene latex (PSL) particle sizes. Two styles of commercially available fabric masks were the least effective with a filtration efficiency of 39-65% for PSL particles, and they performed better as the particle size increased. When the cloth masks were tested against lab-generated whole diesel particles, the filtration efficiency for three particle sizes (30, 100, and 500 nm) ranged from 15% to 57%. Standard N95 mask performance was used as a control to compare the results with cloth masks, and our results suggest that cloth masks are only marginally beneficial in protecting individuals from particles2.5 m. Compared with cloth masks, disposable surgical masks are more effective in reducing particulate exposure.
Just want to jump on the train and say that Xfce is absolutely great. It's very very fast and works well, I wonder why it's not the default on every distribution by this point.
"Working from home has caused commercial office occupancy rates to plummet and commercial property prices to fall in crowded zip codes. Falling property values in cities are likely driven by richer, more skilled residents leaving high-value properties. That will cause a drop in property taxes and strain city budgets." https://www.forbes.com/sites/a...

I ppurchased a couple of "Sand Disk" SD cards for my camera back in January. I put both in my camera (Nikon D7100) formatted both and started taking pictures. Both got to ~50% full then both just died. Stopped working. When I took them out of the camera and put them in my computer, the 64GB SD cards were now 32GB SD cards that could not be read, written, formatted or mounted. Wonder if the same people hawing the fake SD cards are hawing fake SSD drives.
