On World Environment Day, lets talk about Blockchain

Blockchain is, simply put, a distributed ledger in which, every time a transaction takes place, an entry is made in ALL the copies of the ledger. 

Let's say that this blockchain has 2 people. A transaction happens. It is logged on 2 machines. No. of post transactions: 2 

With 3 people: 3 

With 4 people: 4 

Now, lets see the quantum of 5 transactions on these sizes of blockchain: 

2 people: 10 transactions 

3 people: 15 transactions 

4 people: 20 transactions 

5 people: 25 transactions 

This means that as the size of a blockchain increases, the number of transactions multiples. 

All those transactions consume energy and electricity. 

Do they make the transaction 2x, 3x, 4x secure? As compared to ONE backup? 

The simple answer is: NO. Creating n copies of a transaction does not make it n times more secure. The environmental impact is not commensurate with the security provided. 

So this World Environment Day, lets talk about the pollutants of tomorrow - Bitcoin and Blockchain. 

Simple Rules for Life

 1. Limit your banking exposure to two, at most three banks. No more. 

2. Keep at most 2 credit cards - one primary, and one backup. Take the highest stratum available to you. 

3. Never store credit cards on any website. EVER. 

4. Don't keep yourself signed in on any website. Sign out every single time, then clear cookies. Its worth it. 

5. Every few months, go to your Google settings and check your privacy settings. Google changes it automatically. 

6. Keep life insurance. 

7. Go to a local doctor. Go to a local hospital. DO not go to a corporate hospital unless your illness needs the infrastructure of a corporate hospital. 

8. Buy from your local store. Go to the bank branch. These relationships are important. You will need them. 

9. Things are to be used and people are to be loved. Not the other way round. 

10. Do not be in real debt. This means that you may take a home loan, but your assets should be such that you should be able to pay off that loan if the need arises. That's real debt. You are a debtor on paper, but not in truth. Buy the car you can afford to buy off cash. 

11. Always keep an eye on your investments yourself. Find your niche and fit in it. Not in any advisor's advised niche. 

The Gujarati Thali restaurant's signalling system

While watching Scam 1992, Bhatt teaches Harshad the finger signalling system. My son remarked, "That looks so complex! These signals are so subtle." 

And I remembered that the same system works in the Gujarati thali restaurants, and possibly, other Gujarati businesses too. 

What is a Thali restaurant 

Most Indian meals are multi-course by default and they are a riot of textures, spices, flavours, and aromas. 

Representative Image: A thali from Rajdhani restaurant, taken from the internet 

The Gujarati and Rajasthani thalis are the best known examples of these multi course meals. The South Indian Wedding food is another one. 

But in Gujarat and Rajasthan, these thali restaurants are very popular. 

How the system works 

If you have never been to one, here is how it works: 

When you sit down, someone brings a basin and pitcher to help you wash your hands. As soon as you're done, a server appears with the salad and starters. Once you reach main course, your thali fills up pretty quickly. As you eat, the servers move around silently, serving people near you, keeping an eye. If you finish dal on your thali, for instance, a server will appear out of nowhere and offer to refill that bowl. If you want dal, great for you. But if your heart desires something else, and you mention that to the server, the relevant person will be at your table in under two minutes. How does this work? 

My dad explained this to me. The servers don't talk or shout across the hall. They raise their free arm and gesticulate. Servers at the other end of the hall also can see this. The server with the relevant item (each server moves around with a serving tray that has 1-4 items, ready to be served) moves to the right table and person immediately and serves. There are gestures for what is needed where and by whom. 

Sometimes, two separate servers move towards a table on seeing the gesture, but on seeing a colleague has reached, the other turns back to focus on tables they have not visited for a while. 

The other thing that one notices about these restaurants is that you cannot tip an individual server. As you leave, the tip box is at the counter. You place it there. If you try to tip an individual, very likely the effort will be frustrated. 

The Thali restaurant experience is a lot like eating at a wedding. मनुहार or cajoling one to eat more is a necessary part of the service (or used to be). You feel well taken care of because someone arrives to refill even as you finish an item. Needless to add, these are all you can eat kind of service, but unlike a buffet, where you have to get up and fetch food every time, in this case, the food comes to you. 

You might think that a service like this will need a high server: guest ratio. You'll be surprised to know that most Thali restaurants I've been to managed with just the right number of serving staff. They don't appear to be an overwhelming number within the restaurant. 

Any other places where the finger signal system works? 

If you know of any other place where this finger signalling system works, please do share. (The examination hall is not a valid answer :) ) 

The Shagun of Punjabi business communities

When a business was started in a Punjabi trading community, the entire friends and family were invited. It was a celebration. Everyone came and bought something. That was mandatory. 

In addition, they also gave "Shagun" - a gift that is given for good luck, on social occasions. The start of a business is a perfect social occasion to a business community. 

Every guest was sent back with "mithai" - congratulatory sweetmeats to share the happiness with the guests. 

This was not any ordinary mithai. Most businesses start with a prayer ceremony according to the faith of the family. For the Arya Samaji Punjabis, that would be a yagya (havan). For the Sikhs, most likely an Akhand Path (a 2 day non stop reading of the Guru Granth Sahib). For other business families, it would be a prayer to their family deity (for 80% of Punjabi business families, that would be Mata Vaishno Devi), or to Goddess Lakshmi. This mithai was considered to be the prasad (blessing) of that prayer ceremony. 

In India, Shagun is given at weddings, at the start of a family, on entering a new house, etc. But a shagun and a small order at the start of the business, did two things: 

A. The moneys collected from the shagun helped ensure that operational expenses are taken care of for a short while. 

B. The initial orders, no matter how small, ensured a good first day of the business. The Punjabis believe that a good bohni (first order of the day is called a bohni), a good first day of the business, and a good final order of the day is auspicious. A business that does not do well on its opening day is, well, unheard of in close knit Punjabi communities. 

C. This initial order also gives every one a chance to sample your product. Then, when they recommend you to someone, they can say truthfully, "I have tried them and they are good." 

You might think that this is very well for B2C businesses, but as we move into services (CA, IT, etc) or B2B platforms, this practice cannot be replicated. 

Well, the Punjabis have been doing software (film production companies) and B2B (the entire construction and transport industry of the North from Jammu to Delhi) for a long time. 

So, here is how this goes: 

We give the shagun and we make a business transaction - this can be: 

A. A service rendered or resource shared. 

B. A discount if we can be a vendor to the business. We might also throw something in for free. 

C. An order 

D. An introduction to a potential client  

E. Govt and regulatory facilitation. 

Those who can provide vendor services do so at a very nominal rate for the first order. 

Those who can either buy or introduce one to potential buyers do that. 

Where our basic thinking is flawed

 ome things, I think, we need to think differently about:

A. It is not the website's job to do SEO for Google. It is Google's job to find and index the best content on the web. That is their core business model.
If they can't do that (and they are not, as I have discovered since using DuckDuckGo), that is their failure.
But Google has, instead of being the seeker of good content, become the inspector of content - first teaching websites SEO, then changing the algorithm every few years so that people cannot use the rules that it taught them and have to learn new ones. The entire SEO industry is based on our laziness and Google's manipulation of how information is accessed.

B. The attention economy fuelled by Facebook and Google have convinced every individual that it is the job of a good resource to advertise to them. They are not responsible for their ignorance. But they are.

Your attention is of value only to people who are making money from it. Not to someone who will add value to you. When you want value, it is your job to seek out the best resources, and to use them. In India, we used to find good gurus and apply to them to take us. Not the other way round. I found Rashmi Bansal's excellent programs, and she does not advertise. As a parent, I seek out such programs for the child.

What I know about the Pfizer vaccine for children

Last week, some parents of my child's school created a Twitter Storm asking for Pfizer for their kids. 

This prompted me to look at the results of the clinical trials of Pfizer on children and to understand where Indian vaccines are on children trials. 

Here is what I found. This is a summary of findings, in no particular order or form. But all the vital points are here. The recommendation is for me and my child. It is not for you or your child. 

1. Just like the adult trials, the children trials did NOT check to see whether the vaccinated group had Covid or not. They checked for the child being asymptomatic. This means that 100% efficacy of Pfizer vaccine means that all the kids who got the vaccine were asymptomatic. 

This also means that schools that open on that basis of this vaccination are basically unleashing millions of  potential asymptomatic carriers into the world. If there is an immunocompromised child in the school (immunocompromised children cannot take the vaccine) , OR if a child's immunity is not strong enough to manage the infection with mild symptoms, that child is in serious danger because they are going to be exposed to all the variants that their friends carry without symptoms. These asymptomatic carriers also risk carrying the infection to their families. 

At this time, as far as I know, the Covaxin trials have also tested RT PCR only for symptomatic cases. 

2. The mRNA technology has been in the lab for over 30 years. 

The no. of times it has been approved for use on humans: 0. 

But as soon as the China virus erupted, there was fast track approval to these vaccines. Read this for details. 

As far as I know, other than being expensive, there is NO advantage of using gene technology for this application. Dead and weakened viruses have been used for vaccination against viral diseases for a long time, and are, at this time, the safest option (read link above to understand the known risks with mRNA.) 

There is, however, a risk. And that risk is, at this time, huge. If the body does not lead to an immediate autoimmune response (as given in this article), we don't know if any gradual changes will occur. The tech hasn't been around long enough for us to know that. This article mentions that because the shelf life of the mRNA is short, we can rest assured that the messenger is destroyed once the message is read. The question of - Can there be long term effects? is answered in detail - 

Could there be effects decades down the track we haven't predicted? Potentially, but the transient nature of mRNA makes it one of the safer molecules we can use to combat disease.

3. Pfizer is not launching in India because it wants the Government of India to indemnify (not hold responsible) for any adverse reactions. The government has not granted such immunity to any other vaccine manufacturer, including our own Serum Institute of India and Bharat Biotech. Yesterday's paper mentioned that the govt might give conditional indemnity - that Pfizer must disclose all known adverse reactions. But here's the thing - if a safer option is available, as a consumer, I don't want to go with a company that is asking for such indemnity. Such indemnity is, in basic human terms, saying - You can take the vaccine, and if your people suffer because of that, that's not my problem. AKA avoiding responsibility. That tells me a lot about the moral fibre of the company. 

4. The US is using Pfizer for all its citizens. Pfizer is its home grown vaccine. For India, Pfizer would mean expensive imports. These expensive imports are completely justifiable if the protection rate is significantly higher. But that is not the case. 

The US is not importing any vaccines. All the 3 vaccines currently approved for use in the US - Moderna, Pfizer, and JnJ, are made in the US. 

Further, Covaxin's children's trials have started on April 30th. We can wait for them to appear, but since the tech is fairly well known, we know that they are likely to be successful. Indian children have also tolerated such vaccines successfully as part of our national vaccination program. We have NO IDEA how Indians - adults and children, and our unique genetic makeup, will respond to the vaccine. This is not a fancy idea. The variants that have mutated in India are a result of the body's response to the RNA of the virus. These mutations have happened during the RNA- ACE2 dance based on the Indian population's unique genes. 

Conclusion 

So, all things considered, as a parent, and as a consumer, I do not want the government to give indemnity to Pfizer. I do not want the Pfizer vaccine for my child. And I definitely am not sending my child to school on the basis of Pfizer global vaccination coverage. 

There is very little chance that the American population will see another China Virus wave after this immunisation. Because, as Nicolas Wade points out,  it was the US that funded this virus' creation, and the US that will benefit from the vaccine commerce. So, it would not want a second public health emergency. Besides, Biden is in the White House and China is now secure. No more trade sanctions, no more local manufacturing stimulus, no issues at all. It makes sense for China to not cause a second wave in the US. One does not stress one's largest customer, after all. 

But India does not have the same good luck. It is in China's interest to ensure a weak India - both militarily and financially. Only India has stood against China's economic colonialism in Pakistan, Sri Lanka, Nepal, and even Bhutan now. A weakened India, like the one we experienced this month, is very much to the benefit of China. So, i dont think that Pfizer will be as successful in India as it will be in the US.

I did the coolest thing with Whatsapp

Since my friends won't move away from WA and I cannot stay on WA, I did the coolest thing with WA. 

1. Take an old phone which has no SIM 

2. Put it on wifi. 

3. Install WA 

4. Enter the number of  phone. open SMS on that other phone before entering the number. 

5. When WA asks for Sms code, see the code from the other phone and enter. 

Et viola! You can now use WA using a phone number but that phone does not have to have WA. 

That being done, it is a shame that people value their independence so little. We fought 250 years for this independence. 

Today, China has waged and won the 3rd World War. Biden is in the White House, global economies and health infrastructure is dead, and China is the only one left smiling. It did not allow WA to enter and colonise its people's minds. It ensured that mind control and access to information was also detemined by the ruling COmmunist party. 

This explains how India was colonised in the first place. Why India is always surprised by riots. We dont think anyone means any harm, until the harm has been done. :(
