It seems there is no absolute security with this neverending battle. But one can make best use of existing defences. For example, some WWW services use two factor authentication (2FA) when you update an account. The server sends a clear-text SMS message which you enter into your application page. Hackers have tools and tactics to intercept and exploit this procedure.
A hardware security key mitigates this weakness because it has unique encryption codes which can't be modified by software hacks. The key shown is made by Yubico to plug into a standard USB port. When you add this key to your account on Google or Facebook, the service requires you to plug in the key and tap it for login. Then you are good to go.
Keep the key with you as if it were a credit card. If your computer fails or is stolen, you can use the key on another computer. Some phones, such as Google Pixel 4, have a Titan security chip which you can use for account setup. Nobody should use an App or SMS messages for account security. If you have a business which stores private client information, it is more important to use this technology and consult a security specialist.
Yubico Example .. Breaches come to those who wait!

There are many alarming reports about 'coronavirus' but that word is a just type or category. It should be mentioned by name "COVID-19" just to avoid any confusion. Next year there might be a different coronavirus which causes more chaos.
Under an electron microscope, the COVID-19 appears as fuzzy blob with many legs. The image above is more artistic. The spikes on the ball may remind one of the sun's corona. These spikes attach to a human cell which the virus uses to clone itself. Fortunately, it's fatty tissue can be destroyed by common detergents. I use a mixture of water and Dawn in a spray bottle to clean my countertops. Handwashing with soap is better than using alcohol-based cleaners which don't remove the dirt while the alcohol irritates the skin. The alcohol-based is ok for portable use.
Apparently, the virus slowly meanders through the human body such that it takes a week or more for the infection to become evident. Symptoms vary from mild to menacing. People with pre-existing conditions are most vulnerable. If the virus attacks the lungs, the person may drown in their own fluids unless attached to a mechanical ventilator. This is just my interpretation of what the experts explain.

Airbus has a majority stake in the CS300 and probably earns more from it than does Bombardier. They renamed it A220-300.
The original CS300 was late entering production and got a big bailout from the Canadian government. Executives got big bonuses paid for by you, the citizen-taxpayer. So when you fly, there should be a least a seat with your name on it and a free pack of goobers.

Unfortunately, the "Sound Oasis Vibroacoustic Therapy System" is no longer available. Fortunately, cats are plentiful.
Tibetan singing bowls have been used for centuries to provide pleasing effects. You can simulate the affect using a wine glass. First, fill the glass and drink all but a few teaspoons. Dip a finger in the remains and run it gently around the rim of glass so that it starts to resonate. A large glass is better for low frequencies.

All kidding aside, Mr Black is a six year old male Domestic Short Hair/Mix adopted from AVA -- Action Volunteers For Animals. AVA does not have a fixed place, it puts cats in foster homes where they are prepared for adoption in fur-ever homes. They also have a deal with PetSmart which provides a cat coop where hopeful cats are displayed. Volunteers care for the cats. Mr Black was returned to AVA with four cats from a seven-cat home. The owner was "downsizing". He named all his cats with the letter 'B'. So Mr Black was "B.C." which could mean anything. Best Cat, Bad Cat, Big Chicken .. who can say. Unfortunately, his microchip record name is "BC" which I can't change arbitrarily. So I call him "Bix the Cat" which explains BC.
Bix cried on the way home in the pet carrier but shutup when he realized this was not a trip to the Vet. He was skittish for a few days but is comfortable now. He has an ideal weight of 10 pounds and a glossy coat which does not shed like the layered undercoat that Tabbies have. He circles my chair or jumps on my desk to get attention. Most photos of him look like a shadow with eyes. I got one almost good with no flash and the window behind me.

Such a project would never be done in Toronto because the federal and provincial governments, and the city council would debate forever about who designs, who pays, and when it will be done.

There are tons of recipes on the WWW. I just make spaghetti or stew with beef or chicken. Saute is optional for meat because the blending of flavors during pressure cook makes it seem unnecessary. Pasta recipes with tomato sauce need to have the sauce added last to prevent scorching.
The Full Release valve emits a startling blast of steam. Steam is bad for kitchen cabinets so I place the pot on the glass-top range and turn on the ventilation fan before releasing. Also I tap the valve several times to lessen the initial blast.
