Dirty Tricks of KDE Developers

I booted Chimera Linux KDE desktop on live USB.
Google wanted me to Log In but it failed.
Worst scenario was KDE guys wete asking for donations (money) and freezing the desktop. GOOGLE has good reason.
Chimera is not a Time Tested dustribution.
Only a old guy like me is interested in Chimera.
Chimera in Greek mythology is a fire breathing female with a Lion Head.
Chimera Linux is not as bad as KDE developers.
I was trying to get installation instruction for Chimera.
I am going back to Chimera GNOME USB to try again Network Install.
Everybody becoming GEEDY nowadays.
Good Bye to KDE.

Chimera Linux = Installation Failure

Failure most likely is due to Debian does not allow a Live USB to mount root permission or su or sudo.
It is blocked deliberately to prevent accidental ERASE of the hard disk.
But Free BSD did it.
I wanted Install BSD on a 32GB USB.
It assumed my hard disk as an external disk.
I am going to ERASE Netrunner and install Emmabantus 6. Netrunner is based on Debian 12. Emmabantus is based on Debian Trixie (Debian 13).
I downloded the latest Chimera Linux Gnome and tried to install it to a hard disk partition but failed.
Then I booted Base Iso and it says that the best option is Network Install.
I am going to do that with its Plasma Iso booted up.
Problem is it gives detsiled instruction for installation without telling me what is the command for Install.
I tried several of Linux commands but failed.
It is a BSD and Linux hybrid.
This trial is for my book.
I do not like network booting.
It says it is minimal and it is so minimal I cannot install it.
It comes from Spain according to www.distrowatch.com.
I think VOID Linux without a fedktop is a better option but I haven't tried it.

Chimera Linux

     OS Type: Linux
    Based on: Independent
    Origin: Spain
    Architecture: aarch64, loongarch64, ppc64, ppc64le, x86_64
    Desktop: GNOME, KDE Plasma
    Category: Desktop, Live Medium, Raspberry Pi, Server
    Status: Active
    Popularity: 112 (131 hits per day) 

Chimera Linux is an independent distribution which uses an unusual combination of technologies behind the scenes. Chimera Linux uses BSD userland command line tools, the Clang/LLVM compiler toolchain, Dinit for service management, and APK for package management. Chimera Linux strives to keep the design simple while still providing the experience and features most users want, such as multiple desktop environments, Flatpak support, a graphical package manager, and easy access to desktop configuration tools. Chimera Linux does not have a system installer, instead providing manual command line instructions to bootstrap the operating system from a live environment.

Cinnamon Desktop takes staggering 2GB

ARCH derivative REBORN OS takes staggering 2G (little over 1.9GB) to Install Cinnamon Desktop and has no applivations at all. I think it has USB Formatter and USB writer. 
This is the desktop used by Linux Mint.
Even Blender takes only 1.2GB.
I use to grumble saying Enlightenment Desktop takes 421GB but it is much more eligent as a Desktop.
But my favorite light weight Window Manger is IceWM which is 5.6MB when installed.
I think 4M Linux and Puppy derivative EOS litle over 1GB with lot of utilities. 
What a wastage of resources.
One can install Blender, Scribus, GIMP, VLC and Inkscape under 2GB on Debian GNOME.
Debian GNOME takes about 4GB space to install and with another 2GB one can have all the utilities.
Every additional desktop and Window Manager adds to this. Only Debian has Synaptic Package Manager with over 60,000 additional packages which nobody can say I have used all of them.

I just installed REBORN OS with 20GB /root partition and installed everthing including Cinnamon Desktop and I have 5GB left.
I standby my conviction that 20GB is enough for /root and if one has lot of Audio and Video files have a very big /home folder almost the rest of the hard disk.
It is advisable to have / boot, /var and / opt.
EFI partition of about 1.2GB to accommodate SuSe and FEDORA.
Debian GNOME takes about 728MB in the EFI partition. EFI is Essential.

Netrunner UPDATE

Netrunner was installed without a problem.
As expected everthing including LibreOffice seemed to a generation behind.
KDE 5 not KDE 6.
It has Synaptic Package Manager.
I did not make the mistakes I did 2 years ago. Instead of placing Gnome utilities I got Gnome, Budgie and several other Desktops installed.
Synaptic was frozen with the KDE and all the additional applications has to be installed under KDE. 
Things are bit strange to me due to primitiveness of the applications.
I am not sure how long I am going to keep it may be for few days until I got enough infirmation for my book on Linux Essentials.
KDE is an antithesis to me.
At least I manged to get GDM instead of SDDM which I do not like.
Yes, it days it is Debian 12.
I am well into Debian 13 which is fantastic.
However Phosh and Lomiri were available with synatic. I did not try them.
Most have to be done under root but I got a User Account for safely.

Gnome under KDE is big anomaly.
KDE on top of GNOME is smooth. 
This is the warning I am going to give KDE USERS. Even with Synaptic Package Manager is available it is one Linux generation (kernel) old.

PCLinux KDE-Lasted only 20 Minutes in my NUC

Yes, PCLinux lasted only 20 minutes on my NUC.
It advertised that it has Synaptic Package Manager.
It did not.
I looked at its repository.
It did not.
Installed AbiWord.
It assumed my NUC as a laptop.
Ruined my GRUB.
Erased it with REBORN OS, immediately.
I wanted see if there are other KDE dedktops better than BlueStar Linux.
PCLinux was the Ugliest of all KDE desktops.
Even KaOS and Trinity OS appear better for me. I am going to try Netrunner Linux now which was my favourite with Synaptic Package Manager in place.
However, from February 2025, no UPDATES (?Gone defunct), of its ISO Image. 
That is why I did not install it till today.
Netrunner still uses KDE-5 while KDE is now in 6.5 version. 

Most of the Linux Distributions except Debian and a few ARCH based distributions assume that only Windows exist. 
The guys developing so called XX Linux believe that there are no other Linux Distributions available to Test Drive. Besides KDE guys ask for money which annoys me.
If KDE is good people would be willing to pay. I wonder whether KDE guys put a RAW distributions with faults and gut money  for additional "Face Lifts".
Bottom line is KDE unlike GNOME lack software. It another Desktop only.
Redhat and SuSe also use this tactics to luvre clients.
PCLinux fall into this inferiority Complex. That may be the reason, I dropped it long time ago. It is still based on Madriva which has gone defunct.
I pity guys using PCLinux.
These distributions are the ones that bring bad reputation to Linux in general.
That is why I am critical of them.

Celebrations without Microsoft from 2010
 

I stopped using Microsoft from 2007

I am celebrating the third anniversary without Microsoft, this Christmas.

Is there anybody other than Anuradha doing work only on Linux in Sri-Lanka?

Please post an email or comment below so that we can have a private party.

I was trying to catch 100 students (school leavers to train free) from Kandy.

That was a total failure
(blessing in disguise for me) but welcome free time for me to enjoy life with my kids.

SuSe-Community and Making an Image

 

 SuSe-Community and Making an Image 

Edited on the 14th, March, 2011

I am not sure whether the comments I have made below is correct, since I have found the same problem with Debian 6. DVD. 

Unable to copy the DVD image. It is 4.3 GB (same size as SuSe) and Linux unable deal with a file size above 4 GB in one file and has to be broken into two which can be done only with torrent.

PCLinuxfullMonty has restricted itself to 4 GB and Gentoo with 4.4 GB has probably divided the file into two (32 bit and 64 bits ) and by doing that has accommodated above 4 GB.

I hope since the SuSe DVD has Gnome KDE, LXDE and Xfce by dropping one of the latter two SuSe should be able to reduce the DVD to 4GB in future so that image can be saved for posterity.

I hope somebody enlighten me on this issue.

SuSe community has the peculiar habit which they have acquired form Novel and Microsoft annoys me a lot, to say the least.
They let you download (which takes more than 36 hours or more from K-torrent in Sri-Lanka) a single copy of the image and and won't let you copy the image as an archive. In the final seconds of the copying it has a script to abort copying which only commercial companies can use as a ploy to protect the copyright (which I am in total support).
This is not a Linux Tradition even if they are commercially operational.
In fact violates the principles of FOSS and true spirit of open software and OS systems.
When it happened for first time I deleted the image and kept the DVD for installation. If I want I can copy the DVD but always have two copies one for use other one for safe keeping.
Mind you DVD cannot be kept indefinitely and if the image is copied to a external hard drive, a CD/DVD can be written if the DVD in use is damaged.
For example for an emergency but not for re-sale. I am not interested in copying and selling it to a third party.
My intentions are are academic and only for archival and retrieval purposes..

Unfortunately most of the old distributions are not in any archives or servers. The servers and linuxtracker included have the habit of deleting not used (frequently) distributions from the sever to accommodate space in the server for new distributions.

They write automatic script to do this house cleaning job without archiving them.

The point I am raising is relevant now. Currently LinuxTracker is down but gradually adding the images to it's servers and it cannot retrieve even the most recently used distributions quickly enough to get the system running in double quick time and it is a headache and lot of heart burns for many system administrators.

There should be a way of transferring the infrequently used into a system category away from the main stream and thereafter after a lapse of a period if still not used can be transferred to an archival medium. All these cost time and money.

I was once downloading BigDaddy (my favorite PCLinux's original successful version) from a server. If I remember right it was softpedia. Half way through my download (which takes ages from Sri-Lanka) it was no longer available and I was heart broken. I could not finish the downloading.

I made a humble request at PCLinux forum and one nice gentleman let me directed to a server and I quickly downloaded it for archiving. It is live and cannot be installed but I use it for demonstrating the humble beginning of very successful distribution.

Similar incident happened with Pendrive Linux. These was a defect (I got it downloaded from a Microsoft machine with Nero) in the image.

This was the first time I got a bootable Linux Image in a Pendrive. Now even Pendrive site does not have a copy of the Original Image and I cannot get it from distromania or from Linuxtracker.

It is like collecting old stamps and coins.

It has become a hobby and a pastime for me keeping the archives.

Coming from an academic (not commercial) background, simple thing like these matter a lot in the long run.

Commercial investors when they want to introduce a new system they begin by not supporting and then destroying the old system by default making the user vulnerable. Microsoft does this very well.

I cannot understand why Linux does this and good example is SuSe who has got under the fold of commercial CEOs.

Coming back to my story what I did was to make a copy of the image (this is something I used to do for old Distributions without an image but only a CD/ DVD for archiving) with K3B and saved it instead of deleting after the image is written to the CD/DVD.

When I tried and used the saved image for writing to a DVD it gives an annoying warning that the Image " file size is different from the declared volume".

Linux (K3B) checks the file size before writing and gives a warning before it writes to prevent one from copying a bad image and wasting a CD or DVD.

This warning or the deterrent cannot be true since the file image property goes as 4 GB.

These are some of the nuances of SuSe and Mandriva which are driving Linux fans or uses away from them. I cannot simply agree with this ploy and that is why I am moving away from Oracle, SuSe and Mandriva. A CEO with commercial interest makes these decisions and my concern is why can't they openly say DO NOT COPY but use these underhand methods.

Evolution of Gnome

 Evolution of Gnome

Debian Live 9.12.0-amd64-Gnome.iso

This gave a Graphical Installer to install Debian, which I found was easy.

Partition table looked like this which I had no ides.

/root

/var

swap

/tmp

/home

I became aware of /var for variable data and I did not know how to use it.

Icon setup was primitive.

Only Ethernet and not compatible with wireless but whereas Ubuntu could (Emmabantus,too) configure wireless.

So installing new software was impossible and had to be stuck with what came with it.

It had LibreOffice.

Debian installer was clumsy and installing AbiWord was not possible and stuck with Emmabantus which had AbiWord

 These days I had fun with Apache Open Office.

Debian Live 10.12.0-amd64-gnome.iso

Similar to above comment but icon display was much better

Debian Live 11.6.0-amd64-gnome.iso

 Similar to above comment but icon display was much better but no ESP Grub

Debian Live 12 5 0 amd64 Gnome ISO

 This is the most elegant and has the new Calamara Installer.

Its ESP compatible and GRUB Loader is pretty good.

No problem with wireless connectivity.

This is my favourite and I use it on daily basis, it comes with Synaptic Package Manager (in fact Debian Package manger which is extensive) which I prefer to SNAP.

Ubuntu has gone SNAP but Synaptic Package Manager is still available for Ubuntu.

I am going to download all three of these isos from torrent files and see how I got addicted to Gnome.

I actually had the stable version installed in my very old PC and Live CD/DVD were collected for testing.

Yes, Debian 10 is the one who had a panel on the left side and dots on the right side when one sees whole lot of application items.

Ubuntu of cores successfully implemented live session with only a minimal of applications.

Al these images were less than 3GB and now they are nearing 5GB.

That is my conclusions, even Gnome getting bloated with each new version.

All these images had only one peer each.

Thank you to them.

BOX utility has made my life easier.

By the way, I have limited number of USBs and I have Ubuntu from 2020 version to 2024, for USB used up.

I did not do this with Debian since I had been using Debian fr over 10 years.

Nevertheless, I am catching up with Ubuntu.

Those days I had no interest in Ubuntu.

Ubuntu Install was minimal and I got addicted it later since it had the best GRUB file.

Of course I had Ubuntu CD/DVDS from its version 6 in my CD/DVD collection.

Gnome BOX utility is fantastic and I am going to run these isos in BOX Utility and see how Gnome evolved.

Linux is steady and incremental, stable and not flashy like Apple and Windows.

The is for those YouTube Linux pundits, some of whom are hell bent on saying bad things about Linux having not tested Gnome.

All of them only test Linux Mint and do not talk about LMDE (Linux Mind Debian Edition).

I think Ubuntu which is a derivative of Debian became popular by adopting Gnome 10 desktop.

Less I talk about Arch and Manjaro is better for my sanity.

I have been trying Debian from version 6.0 but full adoption was probably from version 9 in 2015 when,  I retired fro the University.

Distortion of Birth Story of Buddha

Distortion of Birth Story of Buddha

My mother wanted to go to Lumbini and I somehow raised the money. However, she did not utter a word after the return having seen the "naked Niganatayan". I was expecting her to ask me for a return journey but she did not. Of course, she visited all the "ata mastana" or 8 religiously important places in in Ceylon.

Later my mother in law paid a visit to Lumbini with my family but I did not. My brother in law foot the bill. She never uttered a word about "Naked Nigantayan" .

I did not join to look after our dog. I give thanks to our dog for not visiting Naked Nigantaysn in India.

I have revised my opinion having listened to Jayarathna Pathiraarchchci.

Born in Teldeniya now under water due to Polgolla dam. 

Attained enlightenment in Dambulla.

Parnibbhana in Anuradhapura.

Relevance of Mihintale is probably related to the Ravana Story. The "cock and bull story" of Vijaya and Mahinda Thera was also planted by Indians where colossal Ravana remnants and caves remained and the Indian owned them by default.

Yes, we have to revisit out history as stated by Jayarathna Pathiraarchchci.

This is stated in the "Gatha" my mother used to recite.

Now I do not believe in Pali at all since Pali a creation by Indians Buddhagosha and Mahanama.

"Yannam padaya Nadiya Puline Che Theire (Teldeniya)

Yan Sathcha Buddha Girike Sumana Che Lagge (Sripada)

Yannattha Yonaka Pure ( Makkama in Puttalam now under water) Munisocha Padan

Than (Three) Pada Lannchana Mahan Sirasa Namami"

 

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 MettaAryans 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 Buddha-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 
in 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 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.
