Global Warming, Floods and IT industry, any connection?

 Posted on November 22, 2011

I have two inbuilt idiosyncrasies 

One is to link any topic with Rebirth.

The other is to link incident to Linux or computers.

This is free of Rebirth and so better read on. 

But this has a real connection with flash floods 

Global Warming, Floods and IT industry, any connection?

I was post postponing writing about global warming for sometime and most of my pieces were related to bird watching and not IT industry.
 
I predicted this 5 years ago (Flooding) and at that time every American Scientist, including Scientific American was skeptic but the email doctoring incident bared before the Earth Summit (in which only European Nations and New Zealand and the former PM Helen Clark stood against that conviction) and all Scientists are in broad agreement, now that the  "Global Warming₹ is taking shape in real time.

I never though the floods in Thailand would adversely effect the IT industry.

There is acute shortages of Hard drives and the supply will fall behind demand by over 6 months.

The best Christmas present one can give this time round is a good external hard drive.

I cannot go for a SSD but bought a SSD hard drive on loan since the vendor guys alerted me well in advance. Even, the computer manufacturing will come down and this will add to the HP Saga.
HP is supposed to be stockpiling hard drives (supposed to be ordered for PCs they discontinued producing) to make gain of the losses they had with tablets.
I never purchase HP but onlt INTEL stuff.

This is a strange world and one does not know which will hit you first (debt crisis or floods).

It is both in 2025 December. 

So don’t load your hard drives with videos and if you have money buy at least an external drive.

Happy Christmas for guys and Girls in the IT industry.

I will be writing about global warming in Sri-Lankan perspective soon and not about computers and IT.

Guys this is a good time to promote Cloud Computing and their Server Capacity.

Hurry Up.

Read my book on "Cloud Computing" in Kindle if you have spare time.
 
This piece is noe in progress in December, 2025

I had very close relationship to Mahaveli Project before, during and after.

First of all, I am a medical guy in retirement with special interest in mother nature. 
I am not an engineer but had many engineering friends than medical.
 
I did some reading and research on Mahveli Project in my spare time. 
I had direct association with the Engineers who directly contributed to the project from design stage to its completion.

To begin with, this is an outline and I am going by my memory. I have a one drawer full of documents in CEYLON and the big Map of the Surveyor General of Ceylon. 
I am now in Australia and I do not have the original material and maps. 
Before leaving Ceylon, I handed over the Surveyor General's Publication, to one of my kindergarten friends, whose obsession is to go and visit each and every remote village in this country. 
Unlike me he has been to most of the places devastated by the current tragedy. 

He must be more shocked than me.

 Background

1. We are known for flash floods.

One cardinal theory of flood management is for every 100 years there going to be a flood that overtakes the previous worst by many a times.

I forget the parentage but it is many a times but let us imagine it is 30% worse than the previous worst.

2. The corollary is that the flood plane has to be identified for the next worse episode and no construction should be allowed, blocking the drainage plane considered to be the next worst.

3. All the governments including the present government ignore this important presumptive fact.

We were fully under prepared.

4. If the volume of excess water in any reservoir is considered to be in excess of the flood plane capacity,  that excess volume of water should be drained off well before the unintended catastrophe in a stepwise pattern.

This can be calculated in advance with a simple mathematical formula.
  
5. Water is a huge Potential Energy and has unfathomable capacity to cause havoc. 
 
It is a fundamental rule to be feared and prepared for.

6. We have 101 rivers in CEYLON covering the entire length and breath of the country

7. We are known for droughts.

8. When I last investigated the factual base, say in 1995, 10% percent of those rivers had gone dry due to consistent droughts.

These river beds have water only during the monsoons or else bone dry.

9. Because of frequent droughts we tend to ignore the potential of floods.

10. Now let me come to the Mahaveli Project.

11. I was totally against the Kotmale Project with reasons.
I used to monitor the rain on yearly basis and keep a  simple record, simply because, the approach road to our house goes under water with torrential rain.
The rain comes down at exact time, during  the rainy season
I come home before the rain and I wait at a higher ground to pick our daughter who is dropped off from the school van at the Panideniya Junction (not Peradeniya junction which is one and half kilometers away).

Three Wheeler drivers refuse to ply on this road that goes under water very rapidly.

It is due to the sudden release of water from the Kothmale dam. 
 
I remove my shoes and tie them with the lace and put them on my shoulder to prevent them getting soaked. They do not come dry overnight, if wet.

My daughter does the same thing with her white canvas shoes.

12. One day, my daughter got almost washed away had I not been there to pull her out. After this incident she cannot leave Panideniya Junction until the water drains off.  In 20 minutes the water drains to Mahaveli River. 
Not a big ask to wait for a few minutes. 
Better option is to beat the rain and come home early

That is why I hate Kothmale Project.

13. Accelerated Mahaveli Project was a disaster.
According to my engineer friends there were many short cuts made to the project proper due to hastening of it.

Proper environmental (flood plane is only one aspect) assessments were not done.

14. I sold my rackety car since our house did not have a garage.
Besides, the access road to our house was built on a stream that had gone dry for many decades.  This access road gets flooded with every rain and I cannot park the car on the main road that also gets flooded.

15. I am glad we left CEYLON.
Had I been there I would have been on this road doing "make shift repairs" to the drain which gets filled up with soil. The drain blocked, the water flows on to the road damaging its surface. 
Ranil Wickrasinghe gave Rs. 500,000/= for repair work of this road when he was PM under Maithripala, on the condition that a large display board be erected at the entrance showing his frontal (picture). 
I am pretty sure it got washed away, this time round. 
The new concrete layout not the tar layout which is expensive and difficult maintain.
The 4th house belongs to a guy who projects himself as a UNPier. He pretended he was instrumental in getting the allocation and I have reason to believe him.
Road in front of our house was not repaired.
We did not have pipe born water during Premadsa regime. We had a deep well and pumped water for domestic use and there was a surface well where I used to take a bath. Having retuned home, after work from the University, I used to fedtch water from the well (kids were small and water was scarce), in buckets. 
I had 22 fish tanks big and small and I never used chlorine treated poisonous water for fish. I may have fetched up to 30 buckets on the day when I was cleaning the fish tanks. Nobody would have guessed, I was a doctor and I pretended no to be. That guy one day asked me, "Are you a doctor" and I pretended not to be.

I cannot count now how many species of fish I had but my favourite was Guppy Fish.
I started breeding Zebra and Gouramis but marginally successful. 
Feeding the fry was my problem.
I progresed to two huge open Cement Fish Tanks. The project was to cut down 85% of the mosquito population which I achieved in two years. I had a huge Arpoco overhead water barrel for the fish tank with automatic refill of the fish tank. I gave up fish keeping and became an Water Lillie enthusiast. 
I had 8 to 10 varieties only one did not bloom over 15 years. One that was stolen (not by me) did not bloom and I say that is the "Anann Thariya Kamma" and never steal even a flower. 
Only two pieces of Dhamma in this piece.

Never lie like JVP and NPP.
Never steal. They are stealing free donations now.

Far off Mahaveli SAGA but worth like gems.

In the current scene, I may have got even washed away and would have become a piece or an element in the government statistics.

My estimate is that the main road got flooded during the devastation and I am pretty sure the access road may have slipped away to the paddy field below.

This scenario is more than likely.
I tried to do an ariel survey using Google but could not. Just curiosity.

There are 3 houses at the lowest level and two of the owners have cars. They were obsessed with maintaining this portion of the road simply because of their cars.
Incidentally, I was the only one having a car in early 1980s. Others did not except a guy who had an official jeep belonging to the Department of Agriculture.
One Sunday, I visited the house of the retired Assistant Registrar Student Services, to ask him whether, I could park my car in his garage and I would pay for the services. 
He did not say Yes or No.
When, I went next time round to ask permission, I saw the garage  was packed with firewood. I knew it was a big NO and made my own assessment of his personalty. 
I manged to find an alternative place and his name was Mr. Nissaaka. 
Few years alter, he fell sick and I did what I could do when he was admitted to a private hospital. His adopted daughter was a technician in the Department of Forensic whom I did not know much. She had joined after I left Peradeniya University..

the guy mentioned above, did not know I was a doctor at that time or pretended that he did not know my status in the university. He may have been a couple of years senior but already retired from his post by that time. This guy had Herpes zoster a year or two later and he became blind in one eye.  
I did not volunteer Acylovar treatment which could have prevented his blindness. It is a cardinal principle in our time not to volunteer treatment unless expressly requested for.
 
"Pinata beheth denna thahanam".

All these incidents made me to get rid of the car which is by nature was a depreciating asset.

16. Coming to the floods, the last major flood was in 1954 and I was not attending primary school, then. But I can very well remember my siblings were at home for over two weeks, not going to schools as usual. We were house bound and I did not know the meaning of floods, then.

I hated rain in any case.

Then again we had a minor floods in between and I got stuck in Natha Devale having brought my mother to see Kandy Dalada Perehara.
That day it rained non stop.
That is the last time I went to see Perahara and I told my mother she has come alone, thereafter.  She did eventually stop going to watch Perahara.
This part is a bit of a misrepresentation due to my failing memory. It is corrected below.
I had come to Kandy alone.

My obsession was to take photos of Elephants stationed in front of Natha Devale.

17. I did not have any premonition of this current catastrophic floods and in any case, it was not due until 2054, according to my statistics.

We are only in to the 70s of that 100 year grace period.

18. That is why I say this is the CURSE brought on by this NPP/JVP Regime who are worse than Niganntayan of India but confirmed Niragamikayo who despise Buddhist way of life.

I am convinced that this catastrophe was brought by an unforeseen CURSE.

19. Irony, is that Buddha was born in Teldeniya which is under water after Victoria Project. Victoria Project was a deliberate attempt by the British Monarch  to bury and erase the evidence that Buddha was born in CEYLON for good.

Gaminie Dissanayake paid the price early in his life due to this Mega Mahaveli Project. In fact, he was instrumental in propagation of the British Process and their Myths and deliberate lies to bury the real history of Buddha.

Chandrika did know of the LTTE attempt to kill Gamnie Dissanayake and my Guess Work or Gut Feeling is that she may have done it herself before the LTTE, for her political gains and reasons.

Of course, she lost one of her eyes as a curse and she was a known proxy of LTTE. 

Subtle CURSE befall on all these nasty politicians and JRJ had a nasty cancer which I witnessed at Navaloka Hospital.

S. W. R. D. is another guy I disliked for many reasons. His "Anda Govi Panatha" (Tenant Land Act) is one of them. 
We lost our prime paddy land to the Anda Goviya (Tenant Farmer) who was a crook. He cheated my mum and one day, I chased him out and said never cross me again. 
I never saw him again and I do not know who owns that piece of land now.
But I witnessed that the paddy land was filled up and a house was built on top which was direct violation of the "Paddy Land Act".
This guy S. W. R. D. brought in dissent, and lawlessness.
To this day, people used to say, his burial site gets hit by lightening as a part of the CURSE, he brought into this Buddhist country.

Disunity!

Mahinda Rajapaksa continued to violate the above ACT by allowing his goons to  fill up paddy land to build houses. This also narrowed flood planes and current devastation demolished these houses built on the reserves. They should not be compensated but they should be made to pay a reasonable fine.

20. I am glad Jayaratne Pathiraarchchi is on overdrive and bearing these facts right and left.

Thank YOU Jayaratne Pathiraarachchi for putting out history in correct perspective. 

21. This piece is out of place, if I do not link to my connection to NPP/JVP and the Indian RAW. 
I think the details are in a separate piece here.
Indians RAW plotted to kill me.
I was 3rd or 4th in their list.
The contract was given to DJVP.

A JVP guy who was in my staff named Ratnayake alerted me. In return, I told him Premadasa goons are planning to kill all of you and find a place and hide. He had kids. He survived but my vegetable vendor and my favorite patient, a little girl of 7 did not.
Neck of the vegetable vendor was slit and he bled to death. Mahaveli security guys did not open the gate, so he could get timely treatment. 
 The little girl also died due to same reason. She had asthma. 
The asthma was brought on by the "Fear Psychosis" spread by the DJVP. 
Of course, DJVO guys were rounded up and killed and the doctor at Manikhinna Hospital used to give me a running commentary of bodies piled up at his mortuary.
 
I stopped calling him after 138 bodies.
 
That number I still remember to this day but real number was far in excess of that number.

The little girl's death made me to revise my treatment protocol.
I give a stock of medicine to last 6 weeks.
I give additional prescriptions with free renewal (notice) up to  3 months. 

I give written instruction in a piece of paper with underlined phrase "do not look for me" but reach the nearest doctor or the dispenser.

22. RAW was behind me because I was working with Americans. 
They knew I had the American Satellite in our Operating Theater.
How they got to know, I do not know.
Most likely guess work.
Only, I knew it was a Satellite.
I quickly sent the satellite to Colombo for safe keeping. If I remember right, I accompanied, it under the guise of taking a patient to Colombo.
 
Indians for ages hampered and undermined our progress.

Do not believe in Indians.
An Indian doctor Metha told me in Sheffield never to believe in Indians.

Indians cheat Indians, so why not cheat non Indians is their moto.

The CRIME Anura has committed is believing in Indians. He is now paying the price for it.

23. In a previous occasion when I was working in the University, I had only 20 Rupees in my hand. I could then buy a packet of Anchor milk (just to remind the price of packet of powered milk under 70 years of misrule). These JVP guys forced the banks to be closed and we made a secret operation to open them on a Sunday and pay the Salary of the University Staff.
This was the most secretive operation I was ever involved in. 
I took my salary and resigned immediately.
I knew the JVP guys would be behind my back and 6 months later I joined Navaloka Hospital, not as a doctor but as an administrator.

About the fresh milk packets and dry milk during DJVP mayhem, I collected them and purchased all dry milk in the boutique which were forced to close by DJVP and stocked them in my dispensary cum hospital. Everybody gets a cup of tea if they visit me and the milk packets, I personally delivered to the door step.
I had a stock of vaccines brought from Singapore and all the High Commission guys used come for the vaccinations for their children. 
All according to British stsndsrds.
I made a healthy profit to buy milk provisions for the needy children in Digana.

24. I was in charge of Foreign Liqueur during trying time of NPP / JVP insurrection.
This was at IMMI.
But I only used our own VSOA.
Never Whiskey but Gin and Tonic was my standard before a Billiard or Snooker Game. 
I used to celebrate Poya Day with VSOA on those days. 
Keys were with me for safe keeping and if I get a order from a distinguish guy (not politicians), I give a call to the Bar Boy and dispense the item.
 
There were 11 foreign country agents with different tastes of alcoholic beverages.

One day, police office came in for a bottle of arrak on a Poya Day.
I refused quoting the law but told the bar tender he can drink as much as he wishes with his uniform on.
 
He did not stay long but had a drink free of charge.

I am totally off alcohol now and stopped smoking at 34. Never a single cigarette in UK. I thank late Mangala Samaraweera and Ranil Wickrasinghe for my abstinence. When they jacked up taxes on alcohol I abruptly stopped and never started.

I drink alcohol not taxes is my moto.

25. Chicken was my favorite taste with alcohol. 
I hated barbecue.
There was a chicken special in my name in our restaurant.

26. Cleaning the Swimming pool according international standard was one of my major duties to prevent Infectious Hepatitis.
It was endemic then.
With our current disaster Infectious Hepatitis would certainly resurface.

27. Killing the stray dogs was another duty using lethal and inhumane strychnine.

28. Writing an introductory Note Book on Tropical Diseases for foreign visitors was another task.
I did not have a Secretary but  used the secretary of the administrator for dictating one piece  at a time.
I forgot to keep a copy but years later redid the writing. 
My blogging and writing started with it.

29. I was into Maps and Map Reading.
I was good in geography at primary school. I could remember all the countries and capitals by the age of 10.
I had only one inpatient.
She was a Mulsim girl of 12 with over 40% burns with certain fatality. I dressed her twice daily with serum seeping. 
My pathology knowledge of granulation tissue and healing process was put to good use. I am still surprised she survived.

I had lot of free time. 
There was a big library belonging to IMMI. 
I used go to the library and look at all the contour Maps of Ceylon in the library.

I did some calculations, to extrapolate Sea Water Rising due to Polar Ice melting.

Each Map was colour painted according Sea Water Rising.
Just for fun.
These Maps I brought home when IMMI in Digana was unceremoniouly terminate by DJVP insurrection.


30. These DVVP guys over 80 came in to our house and threatened us. 
They collected our ID cards.
Stupid guys.
It bumaranged on them.
Police only rounded up the guys possesing the ID cards. They were the ones dumped to Mahaveli River for  crocodiles to devour.

31. One thing, I could not do was to get a job in Northern Territories of Australia and work for at least two years. 
Instead, I went to West Coast of New Zealand but Maoris were alien to me.

I have a book on Ceylon and Rivers and Waterfalls of Ceylon.
You are free to purchase and read.
This is only an introduction.

32. Mahaveli land was sold for Rs.20/= an acre.

Wijepala Mendis was the Minister of Lands.

He purchased a big portion.


The River Mahaveli fascinates me

Not because of its nature but because of its use by ancient kings to protect Kandy city. 

I have a book on Rivers and Water Falls of Ceylon at Amazon, one is advised to read it.

When I was writing this book I did some Research Work and I realized that it's current route is not natural but man made. 

There are only two bridges over Mahaveli in Kandy and both were built by the British to protect Kandy from sabotage.

In my belief Heen Ganga is the only natural stream that flows according to geographical contours with gradual descent, to the Mahaveli River.

I have forgotten the details now.

Coming back to Floods we had a major flood in Kandy when I was a little kid in 1952 or 1954. 


I was not attending school but I could remember for one solid month we were home bound and no schooling for my siblings.

It was very gloomy.

Years later I saw the  stone erected in Kandy, Mulgampola to mark the highest water level. 

I believe this landmark is no more.
Probably removed by the municipality vandals.

The present
Gatambe Vihara was supposed to have not gone under water.
It became famous and prominant, after that fact.

I can remember only one other time that it rained over two weeks during Esala Perahera. I hid in the Paththini Devale for over two hours on that day. 

It was my only shelter. 

I had to walk home to Ampitiya with no buses. 

My mother came with me was a wrong recollection.

I did not go for Esala Perahera for a very long time after this incident.
 

Elephants are my favorites but now I say they should not be paraded for display and they belonged to the jungle.

What I remember as a young guy was that every time I went to Colombo by bus even with minor rain
Peradeniya and Gatambe go under water for a few hours. 
The bus stops at Peradeniya and stay until water receds.

Unlike nowadays, rains were heavy.
No problem, if I come by train.
The train track is at a higher level.

This went on until grand Mahaveli Project was completed and the Maskelliya dam came into existence. Only when there is spill over from Maskelliya Dam we tend to have minor floods in Peradeniya.

The Rugger Grounds at Peradeniya goes under water (not cricket ground, hockey ground and track and field, they were at a higher level). 

No more  rugger played there now, mainly due to clashes of students of the two rival schools in Kandy.
 
There is a stream that flows by the side of these grounds and I used to stroll through this pristine stream looking for
Giant Danios.

Rugger ground is the wettest and the muddiest.

My research work lead me to reading large books on geography.

My particular interest was the stretch of road that leads from Peradeniya to Panideniya. It goes under water ever so often, even with minor rains.  There is a little stream that comes under Kandy Colombo road and then flows to Mahaveli River by the side of the Railway Bridge in Peradeniya.

On the other side of the river is the Peradeniya University. 

I used walk (short cut) to the University on the rotten iron plates on one side of the bridge. I stopped this habit when I detected that big iron planks were missing and nobody bothered to repair them. Big risk of falling to the river if I missed one of my steps. 

I can remember I was made to run over these plates by the seniors as a part of the ragging. I did a sprint and the senior guys took at least 20 minutes to cross it.     

I realized these guys were not my heroes. One of the senior guys said are you mad to run like this. 

That was the end of the ragging.

Coming back again to floods, one of the books said that the next flood beats the one before
by a big margin.

It only happens once only in 100 years.

Now going by 1954 it is 70 years now and current rain in Ceylon epitomizes the said geographical fact.
 
What I want to highlight is the mapping of the flood planes.
 
After every major flood it should be mapped to define the extent of the
FLOOD PLANE and its devastation.
 
No construction should be allowed and the flood vplane should be designated as reserved area and for natural habitat.
 
People who built
quarters within the Flood Plane should be persecuted and should not be paid any compensations at all, for their residences. 

These are done under the pretext of tourist attraction. 

I say tourist should not be allowed to access the protected areas.
 
MCC program of the World Bank and I.M. F.  have mapped these areas with callous disregard to Environmental Impact.

The bottom line is to protect the flood planes without any destruction in the name of shoddy
 development.
 
Our ancestors had harnessed over 100 rivers, without destroying the environment and we should make it a point to respect them protect our country from Mal-designed foreign investment.
 


Mahaveli River Map
 

Mahaveli Ruver is known for the scarcity of its proper mapping.
 
Original Mahaveli River starts from Badulla and drain to the Trincomalay plane.

The original water content is not sufficient for agriculture.

It was supplemented by Kotmalay Oya and Pundalu Oya.

I traced them from the Ceylon Surveyors Map and documented in my book. 

Unfortunately, except for it's basin exploited for commercial activities, the river is not properly mapped for details. 

This is what I have found.
    Nanu Oya.
    Puna Oya.
    Pundalu Oya.
    Kotmale Oya.
    Hatton Oya.
    Atabage Oya.
    Nilamba Oya.
    Nanu Oya
(Peradeniya)


Alfred Cyclone and My Previous Encounters

I have slept through two major catastrophes and the third one is building up.

I would  probably sleep that natural disaster, too.
 
This is just to say I can sleep well.

The first was in 1988 in UK.

I was about to return to Ceylon and the family was packed home in advance. I had to continue another month or so of my official duties in UK. If I remember right house was, No.1, Sanctuary Close, Dartford.
I had done my night duty and returned home in the early hours for my usual after work nap, around 9.00AM.
At about 1.30PM I heard the rattle on our backdoor which was interrupting my sleep. I put the table top freezer, fridge and the  tumbler against the door and went to sleep.
At about 7 to 8PM the biggest thunderstorm of the recent history in UK hit the coast ripping trees, power lines and roofs and what not.
I slept through the entire episode and casually gave a call at 1.30PM, why there is no power.
The lady in the telephone exchange said you are hell of a guy and YOU slept through the biggest cyclone. 
Open your door and see for yourself, that the front parapet wall made of bricks  is ripped off.
The next door neighbor's roof was blown off.
We did not call you since you were up all night, yesterday night.
Have you got any gas?
I said, Yes.
Then boil some water and make a cup of tea.
We got your telephone line working and would get your electricity line up soon.
I politely ask if they need any help.
She laughing said; only if you can climb electric poles and trees.
 
I said no way but I am available for any emergency.

Within half an hour I got my electricity.
These guys who did emergency and restorative work were the best in the world.

Next episode was in 1994 July, six years later in New Zealand. 
Similarly, I have packed our family home and sleeping on a Saturday afternoon. I was thrown out of the bed and I guessed I had a dream and kicked a guy in my sleep and I had fallen off the bed. 
But when I looked at the Buddha Image in front of me on the roof, it was tilted and swinging lightly. Then when looked at the pantry, I saw most of the cupboards open and some dangling.
 
It dawn on me that a major earthquake has hit South Island.
Yes, it was and it was 7.2 Richter Scale and I slept through it. 
But the aftershocks lasted 6 weeks.
I was terrified every time an aftershock hit the floor.
I did not sleep well for over 6 weeks with even a slightest of tremor.
I woke up.
Soon after, I left New Zealand, never to return.
 
It looks like disasters seem to follow me.

Regarding, floods it was frequent in Peradeniya, those days.
Thankfully, we lived on a little hill and water never reached our level.
However, the road get flooded with even a minor rain. If one is caught during rain, one has to take off the shoes tie them up with the lace put them on the shoulder and bent the  trouser up to the knee level and wade through the raging water. 
One day, when I came down to pick my daughter after school, we were caught in a torrent more than usual. With clever manoering we managed to reach for the crossroad. 
I was glad I there when she really needed me. 
No schooling on heavy rain was a golden rule afterwards.
Years later much bigger girl was drowned in a canal in the city of Kandy.

When the Project Maskeliya came in to operation part of water from the Maskeliya Oya was diverted to Mahaveli River upstream so our flood plane receded accordingly. 
I was very much active discussing the flood problem with Mahaveli Engineers. 
All of them (hired hands) were not provided with regular places in the Estate Engineering Corporation, after Mahaveli Project was completed.
That was a crime. 

They left Ceylon.
We lost them with their talents.
I never saw them, again.

This is a summary for those reading this piece from Ceylon.
 
Albert cyclone in Australia
It looks like the Albert cyclone soft landed with category 1 but the torrential rain will go on for a week or more.
Hope floods would not do more damage than the winds with waves over 10 feet hitting the coast and hindering the flow of water of the rivers to the sea.

But falling trees are doing enough damage to the power lines causing interruption to electricity in many regions.

Sunshine Coast is relatively safe but Gold Coast is inundated with rain.
Brisbane that was expected to be hit worst was spared by some grace of Weather Gods.
All shops are closed and we are home bound.
I did keep up till 1AM as  usual but dropped to sleep eventually.
No dreams.
 
We had power cut little over 24 hours.

Complete rest for my NUC and cellphone doing the updates.

Installing SuSe Linux 16 Community Edition-PAINFUL

Everything thing in SuSe Linux is painful.
It tries to take over my Hard Disk.
I wanted Install SuSe on prepared EXT4.
It forces me to choose Btrfs which I hate.
Finally I decided to delete the 5 partitions which was dedicated for SuSe.
It forced me to Select one /root partition.
It allocated 2GB SWAP.
I already have 16GB SWAP.
It did detected the EFI but I am sure it is going to destroy my GRUB.
No home partition to begin with.
Only 769 files.
This time round configured the WiFi.
No option for me to select or delete sofware.
Installation is painfully SLOW.
It is not booting.
EFI was not configured.
I would try once again like Russian Redhat based?
This all to make some editing in my book giving a very poor recommendation.
It looks like it is a Server image and not a dedktop edition

Good Bye to SuSe my old favourite.

By the way, Tumbleweed Live Gnome iso has no boot option.
I am trying to get CachyOS to coexist with Debian.

Hard Disks and Their Speeds

Hard Disks and Their Speeds
Factors that determine Storage Devices

1. Form Factor
It is the chip design parameter that determines which type of hard drive fits the motherboard or cellphone.
Cellphone is a computer.

2. Connections
Type of connection that the device has to fit the HDD, SATA or NVMe drive..

3. Dimensions
Size determine the price and the mass production at the chip factory.


HDD
Drive is considered outdated. 
But this is where I started long before SATA came into existence.
HDD has mechanical parts and has the slowest rate of data transfer.
It's wear and tear is high.
Because it is made of magnetic hardware it can store data for a long time without destruction.
The data transfer is slow due to mechanical parts. This is technically called Latency 

Other BUSS words are Efficiency and Performance. Each device had its own performance quality and efficiency of data transfer.

1. SATA
SATA is considered outdated but I have 3 of them.
120 to 320 to two of 1 terabyte. 
All are functional and I have no desire to go for an expensive m.2 or NVMe devices.
All my academic and non academic data are stored in them. I do not need Google store them in cloud. Infac, I have removed all but the data of the last 3 years.

2. m.SATA
The letter m in m.SATA stands for mini or smaller, I believe 
Above types slot into SATA interface.

3. NVMe 
They need PCIe slot or interface in the motherboard.
It is the most modern.

NAND flash
NAND comes from the computer terminology the NAND gates of memory blocks. This are modern chips which can be programmed beyond binary programs.
I think the technology refers to Non Volatile Computer Memory.
HDD drives have non volatile memory and the Magnetic Tape can Store more data and they are used by network servers.
 
Data recovery is possible  with HDD but in SSDs DATA recovery is next to nothing, if they are digitally damaged.

1. Form Factor 


3. Mounting Options
Ultimately it boils down to read and write and data transfer which is important in playing digital games

I am too, old for fast games but I promote Linux games but not Windows.
Valve's Steam is ruling the game world.

Solid State Drives were developed to replace old CD/DVD drives. Finding a laptop with CD/DVD ROM is a luxury now.

SATA are defined by the so called Form Factor which defined the interface with which it interact with the operating System and the Boot Loader (BIOS and new GRUB).

1.mSATA
Old laptops
Old SATA interface

2. Mini mSATA
New Slimmer laptops and cellphones.
Old SATA interface. 

3. M.2 SATA
Modern laptop with a slot (interface) to mount the disk.
SATA interface

4. M.2 NVMe
PCIe interface
OCI has 3 generations 3, 4 and 5.
They are not interchangeable.
Non Volatile Memory express.
Speed of 3500 MB in Gen 3
Speed of 7500 MB in Gen 4.
Speed of 14,000 MB in Gen 5.
Motherboard's BUSS support determined the speed of data transfer even though they fit into the same interface or slot.
 
Volatile Memory Blocks
Data are recorded in Units called cells. These cells are stacked one above the other likes bricks.
 
1. One brick layer is called Single Cell.

2. Two brick layer is called multiple not Dual 

3. Three cell layers are called Triple.

4. Four stack layers are called quadruple.

 

Partitioning Tools in Linux

Partitioning Tools in Linux
 

Partition Magic is a commercial version now!
 

Gone are the days when I had to install Win98 and then Partition Magic and then partitioning which took ages and then install Redhat or Mandriva or Debian with dual booting.

 Nero was my writing tool in spite of Linux installed on my PC.

Suffice is to say Nero had done enough damage to my CD/DVD ROMs and Graphic Cards.

Then there was no K3B.

Beauty of K3B is it diagnoses the defective CD / DVD and reject them after examination without damaging the RAM or the CD/DVD ROMs.

Next stage is Live CDs starting with PCLinux-2007.

The transmigration and single booting with multiple Linux distributions
in my computer network and liberation from proprietary components has given me opportunity to investigate partition tools in Linux.

My favorite partition tool is and was
Partition tool in SuSe which is excellent and gave me lot of freedom and opportunities.

But then again I have to have SuSe installed to get full use of the partition tool
.
Now
SuSe Studio has spawned a KDE Partition Magic it is rightful I should mention about the others for newbies.

1.
R.I.P (Recovery Is Possible) is one of my favorite Live CD which I use for partitioning.

2.
Damn Small Linux and Gparted were the first of my choices those days.

3. Gparted live CD.

4. Partition Magic CD in zip format only a Linux distribution can decipher is the latest of my utilities.

5. PC Linux, Mandriva were my old friends but PCLinux has dropped DOS partitions (which I keep for spare storage) which is a bit of pain.

My only grouse now is most of the partition tools including SuSe limits partitions to 15 which is absurd with hard disks over 500 GB are on the market and guys like me who want to have several Linux distributions in one box.
 

If one distribution has failed in a trick I mount another and get the job done.
 

For example SuSe gives limited space for Thrash and it cannot delete a large (for example an image of 4GB) file.

Then I mount PCLinux and do the job of deleting the large file with its help.

Do not get fixed to one Linux distribution (especially Ubuntu) since there are hundreds of out there with many utilities like blender, gambas, audio video (Media Box) and many more to have fun with.


To have fun and to have many distributions you need a partitioning tool and one has to master partitioning.


It is as chicken feed now unlike the days I was struggling to get everything right at least once a year in December before I recess for some holiday and relaxing.

Fortunately because my 100 Linux adventure (111 now) I can have a long holiday well before December.

Enjoy all partitioning tools they do not hurt the hard disks unlike Microsoft utilities.

Vijaya Story is a cock and bull Story

Vijaya Story is a cock and bull Story

The facts, mentioned are hearsay and not documented. 

There is an emerging concept in Ceylon, with Stone edits or Sel-Lipi to support that Buddha was actually born in Ceylon. 

For that matter, I do not believe in the Vijaya Story on scientific reasoning.

Word of Buddha reached China 700 years after Parinibbhana and was memorized in Sanskrit.

It reached Burma and Thailand 1000 or more years later, probably by sea route and was memorized in Pali.

Nepal or the Magada State is landlocked and Buddhism did not reach Tibet until 1200 years or more.

 

One should assume that all these countries had some form of a belief system and were not conducive, if not antagonistic to imported form of ideas.

 

China is a good example.

 

Things were recorded in Matale, Aluvihara in Ceylon 1700 years later, after the passing away of Buddha.

 

My point here is, with passing away of time and cultural influence and errors in memory chain, nothing called Pure Dhamma existed but colossal literature, that include Dhammapada, which gives an insight, to the Teaching of Buddha.

Buddhas are not born in a landlocked country, something so small as Magada. 

Buddha is born in Deepa or islands surrounded by sea and his teaching was spread by seas routes. 

 

Historically, land is divided and captured by warring parties for centuries in India which was not conducive for a religion which teaches Avihinsa or Metta.

Aryans are not Indians but the migrated from Eurasian region may be from Tran-Iranian route.

 

The language of Magada in not Pali. 

 

There is no country having Pali as the mother tongue. 

 

I tend to believe Pali was invented by Indian scholars. Buddhagosha and Mahanama to distort the Dhamma from the original Sinhala or Hela (Akuru) Language.

This is where the finding of Jayarane Pathiraarchchi is relevant. 

He has written a book depicting, the old alphabet, to read our Stone Edits or Sel-Lipi. 

His claims are substantial and containing research over nearly a half a century. 

Besides,, Buddha won't use an arcane language to spread his teaching. 

 

His teaching is universal for the entire world. 

 

Dhamma should get stabilized in a country where, it would last long and conducive for future transfer.

 

There is no Buddhism in India, currently.

 

There are no no Indian Buddhist monks.

 

In fact, Indians are hell bent on destroying Buddhism by all means, including writing it in Pali by Buddhagosha and Mahanama, or in Thripitaka to destroy its meaning or to hide the knowledge from the Indian masses. 

 

That was not the intention of Buddha and we are still in Buddhs-Warsha. 

  

Ghoha came from India.

He came to destroy Buddhism (certainly not to alter Dhamma content) and Original Sinhala Language.

 

Pali was not a language belonging to a particular country. 

 

It was creation by Indian using extended Alphabet of Sinhala.

 

There was Baminitiya Saya or famine.

 

During this period Maha Vihara sector came into prominence.

 

They named him Buddha-Ghosha.

 Buddhagosha was a parasite from India.

He destroyed all Sinhala Ola Leaves after translating the Existing Sinhala Knowledge to Pali. 

 

 Indians were using Sanskrit, then.

 

Coming to Vijaya Story,

It is a Cock and Bull Story, after all.

 

This as hilarious as Sinhabhahu Story of Professor  Sarathchadra that Sinhalayos were born after sex with a Lion.

 

It is a genetically impossible scenario.

 

Just to make point, Indian are good at creating stories to propagate their ulterior agenda.

 

1. No credence is given to that the knowledge (Buddhism) could transfer in the opposite direction from Ceylon

 

India to Ceylon, one way traffic and Indian hegemony established in literature. 

 

2. Buddhism was transferred from Ceylon to India and subsequently destroyed by Hindus is very plausible.

 

3. Hilarious part is  Samana Mahinda came down from space using an Indian Vimana.

 

4. He landed exactly on Mihintale exactly when the Ravana King was chasing a deer.

 

5. Following discussion was a literary piece.

I would not waste my time here.

 

Buddha never used such a lengthy story to teach Dhamma.

 

6. Kuveni that was seduced was another vagrant story.

 

In actually fact, Vijaya was deported from India due to his sordid and inhumane activities. 

 

He accidentally landed in Ceylon and the original Ravana Clan fought violently but they were probably subdued by brutality but they were not decimated but retreated to the hill country.

 

You should read my piece on prehistory of Ceylon reproduced, here.

 

Prehistory of Ceylon

Current Ceylon history is a cooked up version with lot of gaps.
 
It does not say anything about the period between 5000 to 10,000 years ago even though evidence is there to suggest that there were prehistoric man living 125,000 years ago.
 
The ancient evidence was deliberately torched to ashes to establish the ownership of the new invaders or migrants.

I have developed rudimentary theory to explains the three peneplains of Ceylon.
 
My belief is that three or four (evidence are there in our moon) meteorites hit the large land mass called Ceylon (completely separated from Indian land mass) even before the formation of oxygen in the atmosphere (which later eroded the evidence of meteorite hits).

Never believe the written (modern) history is my way of looking at reality which is submerged with lot of crap.

Ceylon Prehistoric Data
 
Millions and millions of years ago, the continents of Antarctica, Australia, Africa, South America, and India formed a single landmass, situated somewhere near Antarctica.

This landmass, named Gondwanaland, then broke up.
India with Ceylon and Madagascar attached moved upward into Asia.
 

My theory proposes a different context to the above mentioned statements.

Today, India and Ceylon stand on the same ocean shelf. 

The continental shelf has an average width of about 12 miles around the island, where the mean depth of water is only about 200 feet, beyond which there is an abrupt drop to 3000 feet roughly two miles from the shore. Within 10 miles it drops further to 6000 feet and eventually plunging deep to 18,000 feet.
 

About 12 million years ago, Ceylon started to separate from the Indian subcontinent due to fluctuations in the sea level. 

Siran Deraniyagala says that the sea level would have dropped on at least 17 occasions within the last 700,000 years.
The last separation from India would have occurred about 10,000 years ago.
During the Stone Age, Ceylon was linked to India by a wide land bridge across Palk Strait.
Today, the sea is barely 100 feet deep in the Palk Strait due to limestone deposition.
Prehistoric data are rudimentary in our context and a global picture cannot be made from the available archaeological data.
There are many reasons but for completeness, sake I would briefly mention only a few.
Number one is we never had the scientific inclination to record events accurately. 

The period before 2500 years is only a folklore and romantic tales of many inaccuracies.
 

The prehistoric man probably lived in caves.
They had to share these caves with the big cats, if there were any.
It was probably the battle between the man and the beast.
Probably the man won most of the battles due to their shear numbers and the winning outcome provided meat for subsistence.
When the last of the colonizers arrived from India, there would have been pitch battles which were deliberately deleted from our history books.
Probably our real ancestors retreated and few probably survived as Vaddhas in the jungles and caves.
The colonizers probably brought in diseases with them including small pox, which would have wiped out many natives (almost to extinction).
I have some reservation about the current Veddhas.
There is hardly any difference from the main race except their rudimentary language. 

I believe they were drifters from the main stream who preferred hunting as opposed to rigidly imposed Buddhist way of life.
Then of course some of the Buddhist monks with the inclination for meditation practice occupied most of the accessible caves as their birth right.
They of course destroyed any evidence of or any remnants of prehistoric life for good.
Another conjecture here is that most of the caves of prehistoric importance have taken the name of Alu Lenas meaning caves with ash.
What it means may be that the prehistoric evidence were torched to ashes before converting them to temples by the occupants (mostly Buddhist monks).
I am puzzled why the new colonizers, the rulers, monks and civilians destroyed these artifacts.
One possibility was that they were scared of the demons in these caves and pulverized everything that was prehistoric.
I do not want to believe that scenario since Buddhist monks have Pirith or vocal recitals to protect them.
 

I am inclined to believe the destruction of any artifacts left, going back to 10,000 years was a deliberate act to conceal or suppress the unwritten history probably, the most intense warfare in Ceylonese history, the ancient man had with the new visitors from India.
 

They would have left bony evidence of violence and multiple fractures and pulverizing them to ashes was the only option left for the victors.
When the colonizers of the West came in 2000 years later they did not have any on record of the ancient man to write about.
The archaeological collections, I have extracted from various sources are stated below.
 

One must take them with a pinch of salt.
 

The interpretations, if not biased may be largely exaggerated.
 

They are not my interpretations.

My Interpretations
 
However, I would like to go back to my theory of the Origin of Ceylon with some slant to the prehistoric findings.
There were evidence of sea shells found in the interior of the country such as
Kitulgala (2000 feet above sea level) and Balangoda (2000 to 3000 feet above sea level) plain.
If I repeat the three uplifts of the landmass of Ceylon, it would appear that present Kitulgala and Balangoda would have been under sea water many million years ago.
The first peneplain formed after the original uplift due to the meteorite hit remained at 500 to 1000 feet.
This is probably the current lower plains of the coastal region from sea to the foothills.
The second uplift contributed another 1000 to 2000 feet making the second peneplain at a level of 1500 to 2500 feet.
 

Kandyan Plateau at a higher level and Balangoda Plateau at a lower level.
The third or fourth uplift made the hills in the middle of the country with rugged peneplain that rose up to 8000 feet forming mountain ranges.
What it mean is that the final and the massive uplift due to the last meteorite contributed 4000 to 5000 feet of height to the landmass.
 

Now Kitulgala is around 2000 feet above sea level which is close to Ginigathhena Gap through which the road enters the hill country. This region could have been under water before second uplift of the landmass. The second uplift would have brought the seabed with it sea shells up and some of which got trapped between the two peneplains.
Kitulgala and Balangoda are located in the border zone where the gaps that leads to the upcountry are formed due to erosion.
Of course
Ginigathhena was where the trade passed through from the coast to the upcountry. Any trader would have brought sea shells there. That is the explanation given by the archaeologists (see below).
My counter argument is by the time the sea shells were brought in from the sea (unless very well preserved) they would be rotten (once in Kitulgala).

Far better one eats them where they originated, in the coastal zone, instead of trading with the hill country folks.
 

Of course sea salt was one ingredient that came up through the pass even in the prehistoric time (for preserving food).

The word Bellan in Sinhala means shells.
The word Alu means ashes.

Archaeological excavations indicate that there were prehistoric settlements in Ceylon about 300,000 or even 500,000 years ago. 

There is firm evidence at present that there were prehistoric settlements in Ceylon about 127,000 years ago. The evidence comes from excavations in coast of Bundala, at Patirajawela, and Wellegangoda. 

Settlements of the prehistoric period, known as the Stone Age, dating between 125,000-1000 BCE, have been found at Pidurangala, Patana, Dambulla and Mapagala. 

Settlements of the proto-historic period known as the early Iron Age, dating from 1000-500 BCE have emerged at Ibbankatuwa and Pansalgodella. 

Other possible sites for early iron age settlements are Kadurugoda, Mantota, and Kelaniya.
People first settled in the coastal zones, and then moved up to fertile tracts and to locations, in the central hills where there were mineral resources.
Evidence of settlements could be found in
Kitulgala, Karadupone and Ravana Ella, all entry points to the hills.
 

The central hills were mined for gems in the prehistoric period. 

There are remnants of camps, and caves in the wet zone. 

The camps were small, suggesting occupation by not more than a couple of nuclear families at most. Almost all were close to a stream or spring or were at the confluence of the tributaries with the main river. The network of footpaths that link the existing Purana villages today, pass through most of the sites identified. 

So it is possible that many of these footpaths were in existence during early times. The earliest villages may have been about 3 hectares each.
The occurrence of marine shells at inland sites such as
Batadomba Lena (Diva Guhava) points to an extensive network of contacts (Batandomba lena is a pre historic cave system in Sudagala, 5 km away from the town of Kuruwita) between the coast and the hinterland. There is evidence from Belilena that salt had been brought in from the coast at a date more than 32,000 years ago.
The earliest form of cultivation was chena and kurakkan was the earliest food.
 

Kurakkan came here in 10,000 BCE. 

It is a very hardy grain and was used as a substitute for rice.
There were many varieties of kurakkans.
Rice cultivation can be seen from about 250 BCE. Wetland rice cultivation in its early form was an indigenous development.
Excavations at
Fa Hien Lena near Bulathsinhala, Batadomba lena, near Kuruwita, Belilena, at Kitulgala (Belilena is a famous large cave in Sri Lanka. It is located 8 km from the town of Kitulgala. It holds evidence of a lost generation of Sri Lankans some 12,000 years old.), Alu lena at Attanagoda near Kegalle, Bellan Bandi Palassa near Embilipitiya and Bandarawela, provided information on the early settlers and their habitat.
Fragmentary remains of an extinct race of Neanderthal Man were found. Fa Hien Lena yielded the earliest evidence of anatomically modern man in South Asia.
He was labeled Balangoda Man.
Balangoda Man was at an estimated height of 174 cm for males and 166 for females. The bones were robust, with thick skull bones. The teeth were conspicuously large. 

Balangoda Man appears to have settled practically every nook and comer of Ceylon ranging from the damp and cold high plains such as Maha Eliya (Horton Plains) to the and lowlands of Mannar and Wilpattu and the equatorial rain forests of Sabaragamuwa.
The camps were invariably small thus suggesting occupation by not more than a couple of nuclear families at most. They have eaten a very wide range of food plants and animals. 

They ate wild breadfruit and wild bananas.
They have gobbled up every conceivable animal, from elephants to snakes, rats, snails and small fish. Tortoises and terrapins probably had been consumed. The diet has been well balanced judging by the robust skeletal remains.
Balangoda man, like stone age man elsewhere, had succeeded in domesticating the dog, about 7500 years ago.
Remains of early iron age man had been found in just one site,
Pomparippu. 

The biological anthropology of this Early Iron Age man is different to that of Balangoda Man.
Fossils of animals and plants from the Jurassic period (I have my doubt about dating this far into 65 million years) have been found at
Tabbowa wewa. Fossil bones of rhinoceros were found in Ratnapura.  

Tigers inhabited Ceylon about 135,000 years ago. 

Their bones and teeth were found at Batadomba Lena recently. 

Fossils of hippopotamus, the ridge browed elephant, the Asian elephant, the buffalo, the gaur, (The gaur, Bos gaurus, also called Indian bison, is the largest extant bovine, native to South Asia and Southeast Asia) and the rhinoceros have also emerged.
The island appears to have been colonized by the Balangoda Man (named after the area where his remains were discovered) prior to 34,000. They have been identified as a group of Mesolithic hunter gatherers who lived in caves.
Fa Hien Cave has yielded the earliest evidence (at 34,000 years) of anatomically modern humans in South Asia.
Several of these caves including the well known Batadombalena and the Fa Hien Cave have yielded many artifacts that points to them being the first modern inhabitants of the island. 

There is evidence from Beli-lena that salt had been brought in from the coast earlier than 27,000 years.
Several minute
granite tools of about 4 centimeters in length, earthenware and remnants of charred timber, and clay burial pots that date back to the Stone Age Mesolithic people who lived 8,000 years ago have been discovered during recent excavations around a cave at Varana Raja Maha vihara and also in Kalatuwawa area.
The skeletal remains of dogs from
Nilgala cave and from Bellanbandi Palassa, dating from the Mesolithic era, about 4500 BCE, suggest that Balangoda People may have kept domestic dogs for driving game. 

The Ceylon hound is similar in appearance to the Kadar Dog, the New Guinea Dog and the Dingo. It has been suggested that these could all derive from a common domestic stock. 

It is also possible that they may have domesticated jungle fowl, pig, water buffalo and some form of Bos (possibly the ancestor of the Ceylonese cattle which became extinct in the 1940s).
 

The Balangoda Man appears to have been responsible for creating Horton Plains, in the central hills, by burning the trees in order to catch game. 

However, evidence from the plains suggests the incipient management of Oats and Barley by about 15,000 BCE.
 

The transition in Ceylon from the Mesolithic to the Iron Age has not been adequately documented.
 

A human skeleton found at Godavaya in the Hambantota district, provisionally dated back to 3000 - 5000 BCE was accompanied by tools of animal bone and stone.

Iron Age
A large settlement appears to have been founded before 900 BCE at the site of Anuradhapura where signs of an Iron Age culture have been found. The size of the settlement was about 15 hectares at the beginning but it expanded to 50 hectares, to a 'town' size within a couple of centuries.
 

A similar site has been discovered at Aligala in Sigiriya.


History and Prehistory of Lanka
I am more interested in prehistory since we now possess tools to go beyond 10,000 years of history.
Both genetic and radioactive tools are available.
What we are lacking is materials or specimens of significance.
Let me dish out the written history to begin with.
It dates back to only about 2500 years or so.
Even the Bible writing extends the mankind's
existence to 7200 years or so.
Both Bible and Koran are not old enough to study human existence in scientific sense.
Both were anti-scientific and religious dogmas thought to be sacrosanct.
 
They are no longer not sacrosanct in scientific sense.
 
Let me come to Lanka and forget the rest of the world.
Our Buddhist monks (Mahanama to begin with) cleverly erased the prehistory of Lanka and introduced a mythical history of 5000 years to Lanka.
 
How the name Lanka came I do not know but I feel it means an island.
 
I have devised a hypothesis that Lanka was a much bigger island which went under water due to at least three or four meteoritic hits that devastated mother earth including the Jurassic extinction story.
This country has at least series of three (fourth is under water due to the effect of sea erosion) uplifts according to Adam's and Wardia.
If we had prehistoric man evolving in this massive land the meteorites send them to oblivion except a traces in the north part of the island left after the series of meteorites hits.
Moon landing has recovered at least evidence dating back to 4.6 and 1.6 million light years (evidence).
Moon does not have an atmosphere to destroy evidence but earth atmosphere destroys all the cosmic evidence of meteorites.
We have to collect traces from the space which the current space scientists are exploring.
 
Going back to Lanka for the last 5000 years this country was known for its immense population of elephants.
 
Indian elephants were driven to almost extinction to by Roman War efforts.
 
They probably migrated here from India and survived since local indigenous population were not hostile to them.
 
They were mainly in the hill country and the British drove them to the dry land due to hunting and expansion of the tea and coffee plantations.
 
There were at least three prehistoric humans dating back to 125000 years in and around this island.
 
According to my hypothesis they also migrated from Indian subcontinent or Africa.
 
Any existing ones were destroyed by the last meteorite hit, 65 million year ago (Jurassic extinction).
 
So the last 5000 years visitors came here to capture elephants.
Mind you all my theories end up with elephants and their plight to current day.
 
In fact, I dig into prehistory because of my interest in elephants not because I want to become a prehistoric historian.
 
It was a marathon effort since finding data was extremely difficult.
 
So, Vijaya migration was also one of those elephant expedition went expeditiously wrong for both elephants and indigenous traces of man who inhabited Lanka.
 
Our Buddhist monks erased our prehistory to ashes and build “Alu Lenas all over Lanka.
 
For 5000 years this country was plundered of natural history and a modern history dating back to 2500 years was transplanted.
 
My grouse with Paranavithana and Deraniygala is that they never were true archaeologists (they narrowed their sphere of activity to 2500 years, the legacy left behind by Buddhist monks).
 
So, instead of rewriting our Mahayana or Ramayana history there is LOT left to be explored in this country in scientific sense.
 
There are lot of gaping holes.
 
The exit of British from this country was a true scientific loss since their traditions were not followed after our political independence.
 
Our politicians including dead and moribund leftists were rank stupid and ignited an ethnic war still simmering under the ashes which our history is famous far.
 
They think by turning things to ashes the truth can be kept hidden for ever.
 
There is always microscopic, forensic and genetic evidence left behind to explore.
