Davai, Pustai, Rabota, Skoreye!

 


If there is one word you would catch from the numerous clips from the ongoing Russia-Ukraine war, it is "Dawai!" Even though it sounds like Hindi for medicine, it simply means "Move!" in Russian. In the videos the soldiers and civilians are urging people to try and get away from the gruesome, drone-dominated warfare that had hits soldiers and civilians in both countries.

This word turned up time and again in a book I just finished reading - "A Woman in Berlin". Written by a then anonymous young lady in Germany, it records the last days of the Third Reich. A time when the tide of war had turned. Hitlers armies that had spread out all over Europe and North Africa have all stalled. In Eastern Europe, a full retreat is in progress with the Russians rolling back the invaders, taking back their lands from the ruins of Stalingrad (now Volgograd), across the vast steppes, all the way to the nerve centre of Germany's war effort - Berlin.

It was a difficult time for the civilians in the city - especially for its women. For years they have been hearing the exploits of their own soldiers returning from the conquered lands. Stories of cities and towns bombed into submission, of women raped and children orphaned. Rumours of concentrations camps into which millions of jews, gypsies and PoWs disappeared. Now, in Berlin, the shoe is on the other foot. Russians are all over the city, and they are settling scores.

This book gives us a glimpse of the horrors faced by women in war-zones. The author  - now we know her as Marta Hillers - who was an educated, well travelled young lady whose boyfriend was away on some battlefront. She had been staying alone in a bombed out neighbourhood, scouring around for food and water.
The constant forecasts of death by starvation, of complete physical annihilation by the enemy were so pervasive that we're stunned by every piece of bread, every indication that we will still be provided for. In that respect Goebbels did a great advance job for the conquerers: any crust of bread from their hands seems like a present to us.

Homo homini lupus (Man is a wolf to man)...It's true everywhere and always, these days even among blood relatives...Hunger brings the wolf out in us. 

It's a blessing to be able to pray easily and unabatedly; amid the oppression and torture, in all our despair and fear...

In a city teeming with Soviet soldiers, single woman are easy prey, and they often spell trouble for the neighbours as well.
The most bitter thing in the life of a single woman is that every time she enters some kind of family life, after a while she ends up causing trouble: she's one too many; someone doesn't like her because someone else does, and in the end they kick her out to preserve the precious peace.
Marta gets raped time and again until she figures that be best way to deal with the situation is to get 'protection' from senior officers. These connections not only help her fend off other soldiers but also improve her access to food, books, and work opportunities, first as a translator, and then at a laundry.

The high-level connections also give her the confidence (Nicht haben Angst - Not to be afraid)  to deal with petty thievery, and the mindspace to dwell on larger issues ;) 

It turns out that Russian men, too, are 'only men' - i.e. presumably they're as susceptible as other men to feminine wiles, so it's possible to keep them in check, to distract them, to shake them off...

Recovering a stolen radio by pretending to be well connected as a translator - "However it appears that most of life's mechanisms rely on little tricks like that - marriages, companies, nation-states, armies.
It is at the laundry that we hear the now familiar words - 
'Davai, pustai, rabota, skoreye!' = 'Move, get on with it, work, faster!'...On the way back I was swinging my bucket gaily, in the spirit of 'what doesn't kill me makes me stronger'!.
 Over period 20 April and 22 June 1945, martial law comes into effect. Some semblance of order is restored bringing with it rations, water and electricity supply. 

The memoir ends rather abruptly. The book did not find any takers in Germany and was first published in USA in the mid 1950s. It is only in 2003 that a new generation emerged to look back at the war with a fresh perspective.

This makes you wonder about the condition of women and children in today's war-zones - Sudan, Gaza, Syria, Myanmar, DR Congo, Ukraine and Russia - and the decades it will take for the wounds to heal..

The Body

 


I have been a fan of Bill Bryson for many years now. Starting with "A Short History of Nearly Everything"(2003), I have tried to keep up with his numerous books on popular science that blend hard facts with a wry sense of humour.

"The Body: A Guide for Occupants" is perhaps one of his fattest books. In over 500 pages (excluding the refs and index) it covers not only many parts of the human body but also what happens when things go wrong due to diseases or cancer. 

What fascinated me the most is the number of times he begins a sentence with the phrase "we still don't know", or "It is still a mystery why...".

Take for instance his description of a patient name Frau Deter who approached a psychiatrist complaining of persistent and worsening forgetfulness. She could feel her personality draining away, like sand from an hourglass. The psychiatrist, Alois Alzheimer (1864-1915) now has the disease named after him. Researchers have since figureed out that the Alzheimer's begins with an accumulation of a protein fragment called beta-amyloid in the sufferer's brain. What do these protein fragments do in the normal course? we don't know. Patients also accumulate tangled fibrils of tau proteins about which, once again, we know hardly anything. What we do know is that as these proteins build up in the brain - 
Alzheimer's first demolishes short-term memories, then moves on to all or most other memories, leading to confusion, shortness of temper, loss of inhibition and loss of bodily functions, including how to breathe and swallow...People with the disease die twice - first in the mind, then in the body.
Nobody know why some people get Alzheimer's and others don't. It accounts for 60-70% of all dementia cases, and is thought to affect about 50 million people around the world. Little is known about the remaining 30-40% of dementia cases. We have given some of them unique names and recognise them from typical symptoms but the only thing we know is that is is caused by the "disturbance of neural proteins"! One of them is Lewy Body Dementia which is particularly distressing to loved ones because victims frequently lose inhibitions and the ability to control impulses, so they tend to do embarrassing things - shed clothes in public, steal from supermarkets, etc.,  

BB also has something to say about the limits of "modern medicine". Alzheimer's drugs have a 99.6% failure rate (!), one of the highest in the whole field of pharmacology. At the same time, most  of the money available for research is skewed towards ailments of the rich. There is a whole category of 'neglected tropical diseases' that affect more than a billion people worldwide. One of them, Lymphatic filariasis, affects more than 120 million people. Ditto for leishmaniasis, trachoma and yaws.

Perhaps it takes a kind of mad obsession to tackle diseases of this magnitude, and we owe much of what we know to those who paid with their lives. A German parasitologist, Theodor Bilharz (1825-62) wanted to have a better understanding of a tropical disease called schistosomiasis (akal Bilharzia or Snail Fever), so he bandaged the pupae of cercaria worms to his stomach and took careful notes as they burrowed through this skin en route to invading his liver. He survived this experiment but died at 37 (!) while trying to stop a typhus epidemic in Egypt.

So, as Max Ehrmann says in his Desiderata, "with all its sham, drudgery and broken dreams, it is still a beautiful world!". For the human body, it is still an extraordinary fact that having good and loving relationships alters your DNA...and conversely, not having such relationships doubles your risk of dying from any cause!

Rainbow Trouts in Bhutan

 


I guess it does not take much of marketing to sell a fish that evokes images of kisses, mountain streams and rainbows. 

The rainbow trout, aka Oncorhynchus mykiss, loves cold, clean, fast-flowing mountain streams. Native to the Americas it has, over the centuries, become a valuable table-fish - thanks to its great taste (it belongs to the salmon family), the fact that it can be reared with relative ease in fish-farms, and because it fetches a good price in the markets. In India it sells for over INR 1200/kg and counts among the 'high-value' fishes sold across the country. Globally, the top three exporters of Trout are Turkey, Chile, and Vietnam. In 2023, the rainbow trout market was valued at US$ 4.2 billion 

Inspired perhaps by the success of Vietnam, many asian countries have been trying their hand at rearing and exporting this fish. Bhutan is one of them. With its pristine Himalayan mountain streams it ought to have a natural advantage in this business but the record so far has been limited. What could be the reasons for this? 

Efforts started way back in 2008, National Research Center for Riverine and Lake Fishes (NRCRLF), at Haa. Personnel trained at trout farms in Kokernag, Kashmir, replicated a raceway at Haa, and this has been been the centre for trout farming efforts in Bhutan for nearly two decades. The Trout Breeding Centre at NRCRLF has been producing and distributing hundreds of thousands of fingerlings to affiliated farms which in turn produce around 35 tonnes of fish every year. Yet, even at the most fancy restaurants in Thimphu, you are unlikely to find rainbow trout on the menu. Why is this the case? Where does all the fish production go?

One logical answer to this could be that all the rainbow trout produced in Bhutan goes across the border to the Indian market. It takes about five hours to cross 167km of mountain roads to reach Phuensoling, the border town. Even across this border, competition is likely to be stiff from Indian trout farms. 

In Sikkim alone, for instance, there are 760 rainbow trout raceways with an annual production of 340 tonnes in 2022–23, up from 95 tonnes in 2014–15. The state also operates nine hatcheries, producing 619,000 fingerlings in 2022–23. Next door in Arunachal Pradesh, trout broodstock and seed production is being done in two main hatcheries situated at Shergaon of west Kameng and Nuranang in Tawang district. Shergaon has ova production capacity of 100,000. 

India's rainbow trout production has increased from 147 tonnes in 2004–05 to over 842 tonnes in 2015–16 (31% annual growth rate!), with a notable rise in private sector involvement. Key states contributing to this growth include Jammu & Kashmir, Himachal Pradesh, Sikkim, Uttarakhand, and Arunachal Pradesh . With such competition just across the border, it is not easy for Bhutan. 

Two crucial inputs trout fish farms - eggs/ova and feed - is dependent on expensive imports. Annually about 200,000 one-eyed Ova (fertilised eggs) are imported from Denmark. Specialised fish feed, with a purported high feed conversion ratio (FCR) of 1:1 (!) is imported from BioMar in the Netherlands for around Nu.200/kg. Biomar itself learnt the ropes of the fish-feed business from American companies and is among the dominant players now. Quite amazing to think that fishes being reared in the Himalayan streams need to be fed with something that is imported from a tiny country 7,300 km away!

This brings us back to the Vietnamese. How did they make themselves one of the top exporters of rainbow trout? As in the case of cashewnuts they surely have many lessons for those who want to approach agribusiness with a clear head and a hard nose for business!

Dynamics of the North East


At first glance Sanjoy Hazarika's book may seem rather dated. It gives a snapshot of the North Eastern states up to the early 1990s. 

Much of the turmoil described in the book has died down - insurgencies that roiled the North East for decades after independence has given way to a superlative push for development -  the new longest river bridge in India, 10,000km of new highways, railway links pushing further eastwards,  and ten new airports, a new impetus to the agriculture sector...all this has done much to integrate the region with the rest of the country. And yet, thanks to the recent troubles in Bangladesh, and the breakdown of trust and goodwill bodes ill for the seven sisters. 

This history of the seven sisters is a lot more complex than I expected. It also goes way beyond the unequal Treaty of Yandabo (1826) through which the British grabbed large swathes of Burma into British India.  The vast Brahmaputra valley has seen multiple invasions from the east of whom, perhaps the Ahoms lasted the longest.  Originally from the Shan region bordering Burma and China, the Ahoms conquered the area in the 13th century, adopted Hinduism, married into local communities and ruled for the next 600 years.  Even during this period it seems the tribes inhabiting the hills raided the plains but the rules were sanguine about pursuing them into the hills - 'can an elephant enter the hole of a rat?'

In terms of language and culture, a certain pecking order was imposed on this region. Soon after the British conquest of Assam, Bengali became the language of the courts and remained the official language till 1873. The Assamese in turn tried to impose their language on the hill states much to their resentment.

Partition of British India, tensions between India and Pakistan and  the creation of Bangladesh cut off the North East from its natural trading partners. The most accessible port at Chittagong went to Bangladesh even though it was located in Chakma region dominated by christian tribes. On top of this, power politics in North India forced the NE to subordinate it natural resources to states like Bihar. Petroleum extracted from Assam was sent in pipes all the way to Barauni refinery for processing!

Hazarika's book is a valuable record of the missed opportunities in the North East. It also provides a perspective on how the ongoing transformation of the seven sisters.

Yantras of Jantar Mantar

 


 Jantar Mantar is one of the iconic monuments of Delhi. It figures in almost every representational image of the city skyline alongside the Lal Qila, Qutub Minar, and Lotus Temple. It is supposed to mean "instruments for measuring the harmony of the heavens", and yet there is hardly anybody who is able to explain how these astronomical instruments were used.

 The Jantar Mantar is Delhi is one of the five built by Raja Sawai Jai Singh about 300 years ago. For a city that dates back a few thousand years, this site is relatively new, so it is all the more surprising that there are no oral or written records of the Raja's purpose or intent of building many such sites in North India.

Recently the Hindustan Times seems to have taken some interest in drawing public interest to these monuments. Earlier this year, Aheli Das informed us - "Delhi’s Jantar Mantar observatory on the road to former glory". More recently, Kabir Firaque wrote a more detailed, engaging piece titled, "Delhi Heritage - The Science of the Observatory - How Jantar Mantar Read the Cosmos

Alongside the descriptions of the Samrat Yantra, Misra Yantra, Rama Yantra, Jai Prakash Yantra, it was interesting to know that there are instruments here about which we have absolutely no clue - the Niyat Yantra (the four semi-circles), and the "wall of mystery". The task of deciphering these puzzles has become all the more difficult after earlier attempts at 'restoration' plastered and painted over the graduation markings on many of these instruments.

Despite these constraints, some good people labour on - Dr. Aalok Pandya of IGNTU-Amarkantak, Sheh Kesari, a Ghaziabad based amateur astronomer, and a leading expert, Prof. Virendra Pratap Sharma who is now with the University of Wisconsin. Then there is architect Rachana Sankhalker who has written a graphic novel titled, "The Astronomical Observatories of Sawai Jai Singh" (PDF download available for free!).

Lets hope all these efforts will help us add some meaning what seems to most of us like abstract pieces of art spread out in the middle of a park in New Delhi!

Snooping on YouTube

 


If you are curious about something but nobody is willing to tell you, what do you do?

Recently, BBC reported on an interesting method of gathering market intelligence. The question researchers at the University of Massachussetts were trying answer was - how big is YouTube?

This may sound like a simple question but for various reasons - commercial, or otherwise - this is not the kind of information YouTube, or its parent company, Google, would like to place in the public domain. As the article puts it - 

In its 20 years of operation, YouTube has shaped entire generations' sensibilities and redefined global culture. Surveys show YouTube is the most popular social media site in the US by far, with 83% of adults and 93% of teenagers among its patrons. It's the second-most-visited website on Earth by most estimates, topped only by Google.com itself. But as the platform enters its third decade, the most basic facts about YouTube are still a closely guarded secret.

So how did the researchers at UoM get this information?

They started with the URLs that appear for almost all YT videos. They all start with  "youtube.com/watch?v=", and a unique 11-character identifier. Eg - Gangnam Style's identifier is 9bZkp7q19f0

This is where the raw computing power comes in. 11 random alpha-numeric characters can be arranged in more than 18.6 quintillion ways! So the researchers then wrote a program that would trawl the internet with random addresses and download the videos that scored a hit. It seems to collect the first 10,016 videos, the scraper tried more than 18 trillion potential URLs!

The conclusion?

When Google first acquired the platform in 2006, around 65,000 videos were uploaded every day. By 2022, they calculated that YouTube housed more than nine billion videos. By mid 2024, that number had grown to 14.8 billion videos, a 60% jump!!

In the cat and mouse game of corporates and snoops, perhaps it is just a matter of time before YT/Google comes up with ways to foil this kind data-collection and verification.

Non Volatile Memories

 


Last Sunday I got a big scare - one of my newest external hard disk drives (HDD) let out a few scratchy noises and suddenly stopped working. Its LED light went out and the icon just disappeared from my desktop screen. Disbelief, panic!

I checked the plugs and ports, tried changing the USB port, tried restarting the system but the HDD just would not turn on. I had purchased this Seagate 2TB model just before Covid lockdowns! For a while, I just stared at the screen, shocked, confused, bewildered, wondering if I had just lost my collection of thousands of photographs, music, movies and other important documents.

Not sure of what to do next, iI checked for possible solutions online, hoping for some tips on how to resuscitate a cold metal box that held some of my prized collections and memories.

A YT video, "How Safe Is Your Data?" seemed like a good place to start. I was hoping to learn something reassuring from Christopher Barnatt, the acclaimed guru of Explaining Computers - on the lifespan of hard-drives, solid-state drives (SSDs), and other magnetic, solid-state and optical media. Far from being reassured, this video raised the panic levels!

Consider these facts presented by Barnatt -

  • Magnetic tapes can last up to 30 years
  • Most hard disk drives will last 3-7 years (!)
  • SSDs depend on type of cells and number of re-writes, but should last 5-10 years. However if left un-powered for 1-2 years, data may be lost!

  In other works, as with everything else in life, nothing is permanent. More so in the world of charged electrons - a hard disk drive just wears out of spinning in circles; there is nothing solid about solid-state memory; Non Volatile Memory (NVMe) may be the latest thing when it comes to packing in superlative amounts of memory into tiny spaces but it is still volatile!

I have three HDDs - one each from Transcend, Western Digital, and Seagate. The oldest one is from Transcend and I had purchased it online in Japan in 2010 (15 years old!), and it stopped working last year. I tried accessing it from older laptops and Macs but it just refuses to show up on the desktop even after powering on.

So what is the solution? According to Barnatt, the most durable option (30+ years) is to burn all your important files into optical laser disks (high quality DVRs - read only). This however demands access to specialized equipment. Optical drives have all but disappeared from the new laptops. So the next best option could be to have multiple backups.

 As a first step I urgently needed a full backup of all my photos. Since the total size across HDDs came to around 750GB, I decided to try out the new kid on the block - NVMe SSDs. One thing I liked in particular about this option was that unlike traditional HDDs, you could order these à la carte. You could get the memory chips from the company you wanted (Samsung /WesternDigital / Crucial / Seagate), choose the capacity that I could afford (higher the better + you need to leave some space free for maintenance) and fit it into a a box enclosure of your choice.

So, after doing a bit of research and checking some options, this was my final configuration - 

  • M.2 NVMe SSD enclosure from PI India (INR899) - comes with a GPT drive (GUID partition table), connecting cables (USB-C to C / USB 3.0), heat-sink sticker, pouch
  • Gum-stick card - 2280 Western Digital/Sandisk Blue 580 M.2 NVMe 4gen (INR5399) -- a YT video from PI was useful for making sure it was fitted in properly
  • Formatted on MacBook Air - exFAT (for MacOS+Win access) + GUID partition table (GPT seems more robust than MBR - master boot record) 

 So far the set up has been working beautifully. NVMe cards are so much more compact and seem sturdier than the clunky old HDDs! Now I hope the NVMe card will live up to its claim of being non-volatile.
