Today's thread.
How an ancient Danish King, who united several warring clans, inspired modern Engineers to create a unified wireless standard.

Bluetooth: one protocol to rule them all

#CBG_Thread #EngineersDay 1/n

In late 90s , connecting devices with each other was a big nightmare. Almost every gadget had a custom cable.

And wireless space was fragmented among infrared and proprietary wireless protocols. 2/n

Intel's Jim Kardach and Ericsson's Sven Mathesson were presenting competing wireless technologies MC-Link and Biz RF to industry.

Both got rejected. Later in the evening, they met up over drinks where Sven told Jim about King Harald Bluetooth of Denmark eetimes.com/document.asp?d…

Jim realized that Harald Bluetooth who united the whole of Scandinavia under one great empire was the answer to their problems. The industry needed to join forces and not compete. And thus was born the new wireless standard. Jim created a mock-up of Harald holding a PC and phone

The symbol of new wireless standard Bluetooth was created by joining symbols of initials of king Harald Bluetooth- H and B in Norse .5/n

Bluetooth was far more successful than infra red as it didn't need line of sight visibility. It also implemented frequency hopping technique that was invented by a Hollywood actress Hedy Lamarr . It prevented interference among devices.

It united wireless like King Harald

In case you are wondering why was king Bluetooth called so, it was because his teeth were tainted blue due to his overt fondness for blueberries.

Engineers make the world go round, taking inspiration from ancient, medieval, futuristic and imaginary. n/n

One day, mother nature read Karl Marx and became a communist.

She felt guilty that she had created inequality in topography. "Haves" tall mountains and "have nots" ocean floors.

BOOM! A just revolution then levelled the mountains and the oceans.... 1/n

The oceans were gone and so were hills. A blob of a great swamp replaced them all.
"It ain't pretty but there's equality" , she said.

But her joy was short lived for she realized the horror she had created amongst living. Tall giraffes and tiny moles, cheetahs vs sloths. 2/n

"By Marx!", She swore, "I shall fix it ASAP". And lo the haughty elephants and the meek rats and nimble deer and elegant peacocks vanished in a flash!

She gazed upon her new creation , a creature to replace all creatures.
"Perfect !" , she cried with joy 3/n

There are so many problems with this thread.
1) Assumes dark skinned premise for Asuras. Hence as per him Keralites were asuras.

Many "North Indian" Gods are proudly dark like Krishna, Rama, Vishnu and Kali. So flawed premise.

https://twitter.com/AnandRM_/status/903619562385506304

2) As per Bhagvatam, Mahabali performed the yagna on banks of Narmada and not Kerala so any appropriation of Bali is by Malayalis and not vice versa

3) Bali wasn't killed by Vishnu for a reason. Because barring his ahankar and usurping 3 lokas, he was dharmic. In fact as per the story Vishnu grants him a boon and Bali asks Vishnu to stay with him in Sutala.

Today's thread

Once upon a time Hindi's Devanagari script was written in 2 different ways...

Then a few missionaries in Danish colony in Bengal and their rival press in Bombay changed it forever !

Read on.

1/n

If you read old manuscripts of Sanskrit / Hindi you would notice many strange characters in them. Characters no longer used in modern Hindi.

They were called the Calcutta style of Hindi. While the modern form is called Bombay style.

Why these names? Herein hangs a tale.

2/n

In late 18th century, Baptist missionaries led by William Carey wanted to setup a press in Bengal for printing church literature locally. Denied permission by East India company who feared a backlash, they found haven in Danish colony of Serampore. 3/n

Today's thread:

The legend and history of a trader king, his city state and a clan.

King Agrasen - Agrawals - and the archeological excavations of Agroha, Haryana.

1/n

As per the legend, King Agrasen ruled over the kingdom of Agroha 5000 years ago.

He was a trader king and his 18 sons eventually led to 18 gotras (actually 17.5) of Banias that form the umbrella "Agrawal" business community. 2/n

He established the city of Agroha where everyone was welcome to come and establish business.
The original startup capital.

Everyone contributed one brick and one coin to new trader to help him setup his house and start a new business.

Talk about ancient angel investing! 3/n

Before the Wire, Quint and The Print gang starts talking about how village electrification means nothing as it's not household electrification, just two cents that I learnt from my father who was an engineer with state electricity board.

Electricity is transmitted at very high voltages to cut down wastage. E.g. pinjore shimla line is 132kv.
So village electrification means adding poles, cables to connect to high voltage transmission and then down transformers to bring it down to 220V used at homes.

Once this infrastructure is ready and 10% households +panchayat etc gets electricity it's a proof that the village CAN now receive power. Hence it's deemed electrified

Crackpot science 1 : Supercomputing.
Does the esteemed journalist know about "National Supercomputing Mission" started by Modi Govt with an outlay of Rs 4500 Crores? 2/

Modi's Supercomputing mission is about delivering perceivable results. Like addition of 70 supercomputers to premier research institutes. Still crackpot? 3/
