Pfizer Jab Against Covid-19


Got the Pfizer jab for covid19 yesterday. The clinic was in a sports complex and was very well organised. It took 10 minutes to walk through the various check points, get the jab, and then linger for fifteen minutes in case of shock. I was pleasantly surprised given that there has been much grumbling and frustration concerning the vaccine rollout.  This whole week was fully booked as soon as the online portal opened last week but I was lucky to see a few slots open when I made a random check this week.  However, only two percent of Ontario people have been vaccinated and another lockdown is looming.

Canada was once a world leader in developing vaccines or solutions for Polio and Diabetes. But various governments decided to sell the excellent research facilities. They also got sloppy with the maintenance of PPE for health care workers. Now the Canadian government is finally woke to the fact that we can't rely on other countries for health care materials.  Vaccine labs will open up next year. Better late than never.

Kindle PaperWhite For Reading Comfort


Amazon provides two devices for reading ebooks.  First there is the Fire or other tablet with the Kindle App.  It's pretty good but the display is inferior to the Kindle Paperwhite which has a reflective screen with no glare. It does have a light with five LEDs but they do not shine in your eyes.  They are at the bottom of the screen near the 'kindle' label and they shine across the screen.  They are not noticeable.

The displays of phones and computers have thousands of red-green-blue LEDs. All these LEDs are emitting to produce white which is the default color for web pages.  The blue component is not good for your eyes.

The blue in sunlight provides some healthy stimulation during the day but humans did not evolve to live in constant blue light.  So we should minimise exposure to device screens after sundown so that relaxation and a good night's sleep will follow.

The Kindle does emit some blue light but it is much less intensive than the blue level from phones and tablets.

No Pain, No Gain

Some say "No Pain, No Gain" when talking about sports and muscle training. But suppose you just want to feel energetic and healthy.. pain should not be required. My idea is "train to maintain".

I can't go to the gym anymore and did not find any free weights to buy so I make do with large bottles of water (3 liters = 3 Kilo) which I use like kettlebells. They are used with a swinging motion to stimulate the upper body muscles and joints. I follow that with some pushups. And walk outside 30 minutes per day.

Defend Your Castle With Security Key

Castles of yore had multiple layers of defence. They had thick and high stone walls,  moats, and more walls.  It was very painful and expensive for attackers to breach these defences.  Internet security in the modern world is like this .. black-hat hackers create more clever attacks while security experts devise more defences.

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!

The CoronaVirus Mayhem

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.

The Bailed-Out Plane

Bombardier designed an excellent jet named the CS300 produced in Mirabel.  Online reviews suggest it is a nifty aircraft designed for efficiency and comfort. You should give it a try on your next trip within North America.  Air Canada has about forty of them.

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.

Keep Bailing

Heal Mind and Body With Vibroacoustic Therapy

Vibroacoustic therapy is the use of low frequency vibrations to stimulate body cells into therapeutic states of relaxation and healing. Low frequencies of about 40hertz work best. This can be heard and felt like the open string of a bass guitar. You can buy some pricey tech to sleep on or just get a cat that purrs loudly. Note that white noise machines are not for this purpose.

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.

Meet Mr Black

My client, Mr Black, spent two years in the slammer for the crime of Green-Bin-Cracking. The judge released him today when I proved it was the raccoons that did the dirty deed -- my client just happened to be in the wrong place at the wrong time. Now he is living the good life in a safe house with a new identity.

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.
