Computer Memory

Decided to write some technical history today.

Computer memory can be broadly classified into 3 categories

a. Based on Vacuum tubes. 

b. Based on Ferrite Ring (called as Core memory). This was invented by Jay Forester.

c. Today's, semiconductor based LSI (Large Scale Integration) chips.

The revolution in memory technology came from Jay Forester. For a period of time, the core memory was used in 90% of the computers. No wonder we have the "core dumped" , the famous message we see during compiling C programs.

So what about SDRAM, EDORAM, DDR, DDR2. Will clear this mystery in the next post.

BR Chopra Passes Away

BR Chopra was one of the top film makers of Bollywood Movies. Masala, Masti, Magic, Epic, he tried and succeeded in everything he made. Mahabharat, the epic TV serial on Doordarshan was his defining entry into the small screen. We were glued to our TV sets those days.

A Happy Diwali

Wishing for Peace and Prosperity and Stability.

Diwali Greeting

It is Diwali time. Brightness wins over Darkness.

Righteousness wins over Cheating. World needs peace and the message of Diwali is relevant today as it has been all these years.

Wishing you all a Happy Diwali. This picture is from my brother Mukesh.

Nobel Prize

US is on the lead for the Nobel Prize.
Chemistry they have it all. (though one scientist is from Japan)
Physics is shared between USA and Japan.
Medicine is shared between France and Germany.
Literature is French.

Peace and Economics are due on 10th and 13th October respectively.

I searched the site (www.nobelprize.org) to find the Indians or at-least those born in India who have won the prize.

Among the nominations Gandhiji, Nehruji and Sanjib Chaudhary (CJ Supreme Court) were nominated. Surprisingly Gandhiji never won the prize. It puzzles me to this day.

In 1913 Gurudev Rabindranath Tagore won for Literature.
In 1930 Sir Venkata Raman won the prize for Physics.
In 1968 Har Gobind Khurana for Medicine
(He took US Citizenship in 1970)
In 1979 Mother Teresa for Peace.
In 1983 Subramanya Chandrasekhar for Physics
(He became US Citizen in 1953)
In 1998 Amartya Sen for Economics

Trip to Ayuthaya.

Last Sunday, I decided to go to Ayuthaya. There are many ways to go there. But I decided to take the route that is taken by common people. A taxi would have cost any where near to 2000 Baht or more. And would be going-seeing-coming back.

I took the BTK train to Moh-Chit station. The train ride with good AC is really refreshing. Next I got down and took a bus number 77. I should add here that, one of the security personnel there was very helpful. He told me to take either 77 or 3, which will take me direct to the Bus Station. Any way, the bus ride was nice. It cost be 16 Baht. Once in the bus station, I took the Bus to Ayuthaya. It was again AC. Ride was nice, and in 90 mins I was there. Once in Ayuthaya, I took a motorcycle and went about seeing the place.

You can read some information on Ayuthaya here.

I took many photos on my Casio-Exilim. But I am posting those I took on my Nokia 6300 camera phone.

Enjoy.








Peace in world.

Shoes

I had gone to buy shoes yesterday and wondered, that what is their history? Who wore the first shoes. Since when did shoes become a fashion from a necessity? What are the materials used to make them?
I my home town in Rajasthan, India, shoes are made of camel leather. They are quite different. We call them mojri. And during old times, the shoe or mojri as we call it, would eat into the legs. We had to oil it.

Mojri looked like this.



Picture has been borrowed from rediff. Also it is interesting to read the history of shoes here.

Smallest

I was surfing the net to find the world's smallest countries. I found a link here.
If you add up the population of the 17 countries listed here, it is still less than a medium sized Indian town. I am surprised how people feel and live in such small countries.
The link is here.



Next I started to look for the smallest people. I found a site about Primordial Dwarfism. It is essentially a rare case where people grow very slowly. Much better than me I think the video shows it all. I searched further and found this site. There was reference of an Indian there. This caught my attention. His name is Aditya "Romeo" Dev. He is a body builder and recognized as the smallest body builder both in Guinness and Limca book of records.

A picture is attached.

Jodhpur - Stampede

It is indeed a sad day in Jodhpur.
Reading news reports, the toll of the people who have died has already crossed 100. For Jodhpur this is a very big number. There has never been such a tragedy. The Chamunda temple is on one corner of the Mehrangarh Fort. The route to the temple is narrow. The temple itself is not so big. On the first day of Navratri there is anyway a very large rush. 20 years back during my college days, I too used to go to the temple. There used to be quite a large crowd on the first day.

20 years on, devotees have increased ten fold, but the temple size remains the same. Everyone wants to rush. Ever one wants a glimpse.

Thailand - Beautiful Temples

Thailand has some of the most beautiful temples I have seen. The Buddhist temples are just breath taking. So is the river. The size, the flow, the people, the boats everything. Where ever rivers have flowing water, culture has developed. Temples, places of culture, literature and fine arts have all evolved around rivers. No surprise, in India, rivers was where civilization flourished.



The picture on left is of "Wat Arun". In Thai, temple is called Wat. Arun means Sun in Sanskrit. The above is temple of dawn. During Sunrise, it looks just marvellous.



The picture on left is Wat Rakhang. Rakhang means bell in Thai. Legend says that during excavation of the site to build the temple, a large bell was un-earthed. That's how it got its name

Lehman Failure

I never like to write on such issues. But the failure of Lehman raises a lot of questions. The issue of financials does not interest me. What worries me, such a big corporate house how can it collapse. The people working, so well qualified, PHD's, from prestigious management institutes of the world (In India from IIM), all management tools, best brains everything was there. Then what went wrong. Was it wrong Policies, wrong direction, or aiming at just profitability, lack of decision making, lack of check and balances, lack of looking into future.

Is it that our educations is not complete, is it that all the quality initiatives, management principles, economic theories, certifications just for name sake. All companies in the world have to start thinking.

Companies have three components to look into. Its business principles and ethics, its employees and customers, and shareholders. The importance should always be in this order only. The image of the company should be build on principles and ethics it demonstrates and not just states, money should be treated secondary, decision making should be distributed, and checks and balances should be effective. Without which such news will keep coming up. A small search on google will give you a financial firms list that have collapsed or fainted in the past.

The impact on countries like India cannot be ruled out. Where are the economists, political thinkers, university professors, politicians, new channel reporters etc doing? How come none could ever think of this? How come none read reports, analysed data and yet allowed their students/peers/friends etc to join? It creates a big doubt on their analysis skills. Can such thing happen to our banks, financial institutions, corporations. How much are we impacted. Do we have honest figures?

It worries. The good old advice fits. Invest in what is worth the investment. Nothing better than gold.

Safety Pin.

Walter Hunt (re)invented the Safety Pin. I was thinking the other day to search for all those things that are so common around us, that we have been using since childhood, and find out, who invented, who made it famous and surprisingly the invention has remained the same for so many years. Safety pin has very little improvement in both design and complexity. Only it has been used in so many places, it has gone way past that being just a safety pin.

Do send some photos of usages of safety pins.

Google has a browser. CHROME

Google has a browser finally. It has been a long wait. It was surprising that this net company which has become famous with its no-nonsense products, was lacking a browser. Firefox somehow filled the gap all these years. The browser is still in beta. Now GMail is also in beta, so don't know when the beta tag will go away from Chrome. Yes the browser is called Chrome. As of now only the windows version is available. I tried it on XP and Vista, and it worked fine on both. (It is meant for these two OS only). Just to extend my luck, I tried to download it on Windows 2003, but it failed. Linux, Unix versions are yet to come. To download you can go here.

GMail still in beta.

Many have already written on this. You can go to Google and search. I am still surprised. They should have come out of beta quite some time back. The product is good, reliable, handy, simple but powerful features. Probably BETA means something else. Probably it means Better Email Technology Always.

Yishun Celebration : Dance from India.

At Chong Pang yesterday (16/8/8) we had in the amphitheatre, a wonderful program. Among the other singers and dancers, there was this group from Delhi, (it looked from Brij, Mathura). They did a great show. The audience, a majority of which could not understand Hindi, but still were spell bound. A great performance. They are now in the Laxminarayan Temple, Little India, till Janmashthami.

Independence Day

Freedom comes with responsibilities. Comes with ownership. Comes with planning. Plans are made to be acted upon. More than making resolutions, and speeches, and sweets, Freedom comes with contemplation. A time to refresh, rejuvenate, and appreciate what is all there, and decide to make things better, makes things fundamentally better. India needs cleanliness. Freedom from dirt. Public places need this freedom from dirt.

Life Busy Lately.

Lately was not able to put anything on the blog. First of all I have moved over my laptop from XP to Solaris. So it was taking time to get familiar. Then the routine of downloading, and more importantly hardening the OS. Solaris has had a lots of improvements. But for those who are windows users, they need to get adapted to the "unix" culture of getting things done. By the way, Solaris is free and can be downloaded. So I see this now often on my laptop.

The Jodhpur Dream

The fort is impressive as one enters jodhpur. I belong to this city, studied here, but somehow there is something hugely lacking here. The rush you can see everywhere is towards two things a. Handicrafts. b. Accommodation. Guest houses, hotels, and what not. This has led to secondary things like taxis, and shops selling everything from anklets to elephant carvings.

Is the spirit of Jodhpur going to stay alive?

I keep asking myself, what can be done, to bring this city to the notice of the world in either knowledge economy. How can tourism be made a cultural center rather than a money making industry.
