This 20 year old website Hosts Just One image Everyday…Has Millions of Fans !!!

Twenty years ago, two astrophysicists – Jerry Bonnell and Robert Nemiroff – created Astronomy Picture of the Day (APOD). The website is simple and harkens back to the days of the early web: Every post is just one image and a bit of text describing the photo, with links out to sources of information.

During its first year, in 1995, the site received about 12 visits a day. Today they’re way past a million daily visitors, according to The Verge.

The two are active researchers at the NASA Goddard Space Flight Center. How did they become guardians of the treasured website?

“So we were getting these emails that had these image attachments, sometimes about the Hubble Space Telescope, sometimes from something else, and the people sending these emails had no idea what that was. It would say, ‘Look at this, it’s colorful and something astronomical. Isn’t that cool?’ So we thought maybe something we could do was take these images and explain them one after the next,” Nemiroff told The Verge’s Sean O’Kane.

How do they chose what to feature on the site? Well, it’s a bit of personal preference:

Robert Nemiroff: I just like the stuff where you look at it and say “Wow, what’s that!” I’m somewhat jaded after 20 years. It has to work for me before I try to make it work for other people.

Jerry Bonnell: I seem to be a sucker for the big, beautiful spiral galaxy images.

Back in those days cameras with high-enough quality to take great space pictures weren’t as plentiful. They were genuinely worried that they’d run out of images to post.

As Nemiroff said:

Before we posted our first image we debated this, Jerry and I, as to whether we were going to run out of images in a few days and then say, “Well that was stupid.” But actually there were many images around even back then. And NASA’s Ranger series took tens of thousands of images of the lunar surface, so if we had to we could just start putting up other pictures of the lunar surface. “Here’s another crater that’s a little bit different than yesterday’s crater.” But we never ran out of images.

And Bonnell:

I used to have to be more proactive. I would explore what was online and available in the NASA archives online, and I would also make occasional trips to photo libraries that I could find at Goddard and NASA headquarters and look at the prints.

Now, the two-person team gets hundreds of submissions of images from their millions of fans. They still do all the work just the two of them, though:

I usually do the beginnings of the weeks and Jerry does the ends of the weeks, and Wednesday can go either way.

I will do several in a row. I’ll do most of my week maybe on Thursday or Friday, sometimes on Saturday or Sunday. Sometimes I’ll leave Wednesday to the night before in case there’s some kind of breaking news. Jerry will do the ends of the weeks, he usually waits until the night before, and works on it during the afternoon.

To celebrate the anniversary, the two re-created Johannes Vermeer’s paintings The Astronomer and The Geographer using more than 5,000 APOD images that have appeared during the last 20 years.

” What LIFE on Mars would be …” ?

Could

IN A quest to see if people could survive living on Mars, NASA sent six scientists to Hawaii for eight months in an enclosure that simulates the conditions of life on the Red Planet.

This meant that fresh air, sunshine and fresh food were all off the table. The only food available was anything that could be freeze-dried. If they wanted to talk a short walk outside their 11-meter diameter dome, they even had to chuck on a space suit.

They were monitored by surveillance cameras, body movement trackers and electronic surveys.

Last week the crew were finally free to leave their Mars dome.

Crew member Jocelyn Dunn told AP it was awesome to feel the sensation of wind on her skin.

“When we first walked out the door, it was scary not to have a suit on,” said Dunn, 27, a doctoral candidate at Purdue University. “We’ve been pretending for so long.”

The dome’s volcanic location, silence and its simulated airlock seal provided an atmosphere similar to space. Looking out the dome’s porthole windows, all the scientists could see were lava fields and mountains, said University of Hawaii professor Kim Binsted, principal investigator for the study.

Tracking the crew members’ emotions and performance in the isolated environment could help ground crews during future missions to determine if a crew member is becoming depressed or if the team is having communication problems.

“Astronauts are very stoic people, very level-headed, and there’s a certain hesitancy to report problems,” Binsted said. “So this is a way for people on the ground to detect cohesion-related problems before they become a real issue.”

Spending eight months in a confined space with six people had its challenges, but crew members relieved stress doing team workouts and yoga. They were able to use a solar-powered treadmill and stationary bike, but only in the afternoons on sunny days.

“When you’re having a good day its fine, it’s fun. You have friends around to share in the enjoyment of a good day,” Dunn said. “But if you have a bad day, it’s really tough to be in a confined environment. You can’t get out and go for a walk … it’s constantly witnessed by everyone.”

Could we be living on the Red Planet soon?

The hardest part was being far away from family and missing events like her sister’s wedding, for which she delivered a toast via video, Dunn said. “I’m glad I was able to be there in that way, but … I just always dreamt of being there to help,” she said.

The first thing crew members did when they emerged from the dome was to chow down on foods they’ve been craving — juicy watermelon, devilled eggs, peaches and croissants, which was a step up from the freeze dried chilli they’d been eating.

Next on Dunn’s list: going for a swim. Showers in the isolated environment were limited to six minutes per week, she said.

“To be able to just submerge myself in water for as long as I want, to feel the sun, will be amazing,” Dunn said. “I feel like a ghost.”

Amazing Vertical Take Off…Boeing 787-9 Dreamliner…!!!

IT has to be seen to be believed.

In the lead-up to the Paris Air Show, which begins on June 15, Boeing has set the bar high after releasing a video of its newest version of the Dreamliner aircraft — the 787-9 — performing some impressive aerial moves.

But it’s the takeoff which has everyone talking as the passenger jet makes an almost vertical ascent seconds after leaving the ground.

The steep climb looks impressive, though it has its doubters.

Boeing 767 pilot Patrick Smith told CNN: “It looks like the takeoff is at a near vertical 90 degree angle — trust me it’s not.”

He said a 787 with passengers making a 20 degree pitch-up on takeoff would be pretty strong.

“Presumably the plane was very light because it wasn’t carrying any passengers, probably had a very light fuel load, no freight, so it would have been able to perform a steeper than normal ascent — but not to the extent the video seems to show,” Smith said.

That’s steep ... the Boeing Dreamliner 787-9 takeoff

Jamshedpur’s Plastic Roads…An Eye Opener for all Indian Cities…

Disposal of waste plastic is no longer a problem in the steel city with Jamshedpur Utility and Services Company (JUSCO) using bitumen technology on waste plastic, ranging from polybags to biscuit packets, for constructing roads.

Tata nagar roads jamshedpur

JUSCO, a 100 per cent subsidiary company of Tata Steel which maintains and provides municipal services in Tata command area of the city, has constructed 12-15 kms road in the steel city as well as Tata Steel Works besides widening 22 roads using the environment-friendly technology of utilising waste plastic.

Tata nagar roads jamshedpur -jusco

As far as we know, Jamshedpur is the only city in eastern India where bitumen technology (Dry Process) patented by Thiagarajar College of Engineering (TCE), Tirupparankuram, Madurai, has been implemented on accumulated waste plastic for the first time”, Gaurav Anand, Senior Manager (Quality Assurance) of JUSCO, said today.

Claiming that there is no maintenance cost involved for the first five years, Anand, who is an environment engineer, said that for every stretch of such one km long and four metre wide road, one tonne of bitumen costing Rs 50,000 is saved.

The use of bitumen has been reduced by 7 per cent ever since JUSCO began using waste plastic in road construction work, he said, adding that the quality and longevity of roads made of waste plastic-aggregate-bitumen was two times better than bitumen road.

roads made from plastic by JUSCO

Describing plastic tar road as a “new pathway”, Pratyush Dandpat, Deputy Manager (Quality Assurance) of JUSCO, said that the technology turned out to be successful.

Besides being water resistant, it has better binding property, higher softening point, can withstand high temperature and higher load, has lower penetration value, costs less as compared to bitumen road and has no toxic gas emission, Dandpat said.

Though there is great demand for the technology, including from Chattisgarh, Himachal Pradesh, Uttarakhand and Jharkhand governments, but “we do not have any plan to commercialise it but to serve society. We have even received a request from Nigeria, which wants to replicate it in their country”, Anand said.

Due to the JUSCO initiative, the city will now have strong, durable, eco-friendly roads which will also relieve the residents from the sight of heaps of plastic waste.

“Here’s why no one has found a trace of missing Flight MH370….”

A Texas A&M University professor and his team in Qatar have a mathematical theory about why search crews have found no trace of Malaysia Airlines Flight 370 more than a year after it went missing.

Dr. Goong Chen, whose research on this theory was published in the American Mathematical Society’s journal, argues that the plane could have nosedived into the Indian Ocean at a 90-degree angle and remained somewhat intact as it sank to the bottom.

At 1:30 a.m. on March 8, the plane carrying 239 people dropped off air-traffic-control screens, less than an hour into a flight from Kuala Lumpur to Beijing.

One of the biggest mysteries surrounding Flight MH370 is the fact that, despite experts tracking the plane’s satellite pings to the southern Indian Ocean, searchers have never found a debris field or oil slicks from the supposed crash.

Texas A&M noted that in the case of Air France Flight 447, crews recovered thousands of pieces of floating debris from the Atlantic Ocean just days after the plane crashed in 2009.

Chen explains that if the plane were to enter the ocean at another angle, it would have created a large “bending moment” from the external force of hitting the water, causing the fuselage to break up.

In this type of situation, there would likely be a field of floating debris on the surface of the water.

But a vertical entry would be much smoother, with a smaller “bending moment.” The plane’s wings would have likely broken off immediately, but since they’re heavy, they probably would have sunk to the bottom of the ocean.

So if the plane nosedived into the ocean, it could have sank somewhat intact and landed belly-up on the ocean floor, according to the research paper.

The ocean’s current would have guided the plane to its resting place at the bottom. Lightweight debris like seat cushions and passenger belongings probably wouldn’t be able to float to the ocean’s surface if the plane’s body sank intact.

The plane stalling from a steep climb, aircraft mechanisms malfunctioning, and the plane running out of fuel could have caused MH370 to plunge into the ocean at a sharp angle, according to the research paper.

Chen and his team created simulations of what the descent might have looked like:

The plane entering the water at this angle wouldn’t have created the same large waves as an entry at a lesser angle. Big waves would have likely caused more break-up of the plane at the surface.

The animation below shows the supposed distribution of pressure. The paper notes that aviation experts say that how a plane enters the water determines how it breaks up.

In other scenarios Chen and his team looked at, the plane’s angle of entry would have created bigger waves and more pressure, which likely would have caused the plane to break up more near the water’s surface.

Chen and his team concluded that based on the various scenarios they mathematically examined, a nosedive is the mostly likely explanation of what happened to the plane. If the plane had entered the ocean at a different angle, the paper notes, search crews would have likely found debris by now.

“This particular assertion is speculative but forensic,” the paper concludes. The team noted that they based this theory on computed data, aviation precedents, and atmospheric and ocean surface conditions.

The disappearance of MH 370 is one of the most bizarre and tragic aviation mysteries of all time. Investigators have not offered any conclusive explanation as to what happened to the plane after it disappeared from radar.

Australian officials announced last month that teams are expanding the MH370 search area in the Indian Ocean. They said that if the plane isn’t found there, they’re not sure where else to look.

Super Villages of India…

Once in my college hostel lift, I bumped into a fellow hostel-mate who was wearing a T-shirt that showed a village couple dressed in traditional Rajasthani attire and sporting farming tools in their hands. While I complemented her on that T-shirt, her reaction hurt me a little. She said it depressed her that people are making money by selling T-shirts showing backward side of India.

I could not retort to her then, but I guess this list will make her and others who think less of our beautiful countrysides, understand that if anything at all, we should feel proud of living in a country with such amazing villages that are doing exponentially well for themselves and for India at large. Indian villages are deeply rooted in their traditions and some are dangerously blinded by them, agreed. But then that does not mean we should overlook the ones that are flourishing at a faster pace than some of the most famous of Indian metro cities.

So here goes.

Kasol- The Mini Israel of Himachal Pradesh

 

6_Kasol-(2)

The scenic beauty, pristine hills, pleasant climate, and low habitation are the reasons why it is becoming one of the favourite destinations for backpackers. And the increasing number of tourists has finally led to the installation of an ATM machine in the village.

-The village is flooded with bars, internet cafes, and guest houses. But regardless, the beautiful scenery of the village remains intact and breathtaking.

-It witnesses a large firangi crowd consisting mostly of Israelites and owing to this fact, it is also informally referred to as the mini Israel of Himachal Pradesh.

 

Hiware Bazar (Maharashtra)- Possibly the richest village in India!

1_HB

-Hiware Bazar has transformed its sad history into a successful present under the able guidance of Popatrao Baguji Pawar, who came to power as the sarpanch (village head) of the village in 1989.

-The village was hit by a severe drought in 1972 because of which villagers had started to shift out from Hiware Bazar to other neighbouring areas. But when Pawar came to power, the village started to experience good changes like ban on addictive substances, and  encouragement of rainwater harvesting and cattle farming.

-It is thanks to this good transformation, the per capita income of the village increased from Rs 840 in 1995 to about Rs 30,000 in 2012, and this development has now resulted in as many as 60 millionaires in the village.

Punsari (Gujarat)- A village with all the essential modern facilities

2_Punsari

All the people of the village are provided with a 24 hour Wi-Fi facility.

-Schools are equipped with CCTV cameras and digital technology is used to impart education.

-The villagers are given accidental cover of Rs 1,00,000 and medi-claim cover of up to Rs 25,000.

-A 20-litre can of clean drinking water can be availed for just Rs 4!

-The impressive model of the village has also been appreciated by the delegates of Nairobi who are planning to replicate and implement the model design of Punsari in the villages of Kenya.

Mawlynnong Village (Meghalaya)- Asia’s cleanest!

3_Mawl

-The waste matter in the village is dumped in dustbins that are made of bamboos. The waste is then thrown into a pit, and finally ends up being used as manure.

-Plastic bags and smoking- strictly banned.

-People who litter around are fined. Those who cut trees are also fined (although that is a rare sighting here).

-The Khasi society in the village follows the matrilineal system whereby, property and wealth are transferred from the mother to the youngest of her daughters, who is also entitled to keep mother’s surname. Also, it is not an unusual thing to see women running shops here while their men tend farms.

-Literacy rate- 100%

Chappar (Haryana)- Birth of girl child is celebrated with sweets here

5_Chappar

-It is an extremely happy change considering the fact that Chappar is located in Haryana, the Indian state notorious for having the lowest girl ratio.

-After many years of facing suppression, the women of the village have stopped hiding their faces in long ghoonghats (veils).

-And yes, the sarpanch here is a woman known by the name Neelam. :)

Ziro- Included in India’s tentative list of UNESCO World Heritage Sites

8_Ziro

Pine trees decorate the hills in this region and mountain rice cultivation is rampant across the entire town.

-It is home to Sidheshwar Nath Temple. The linga in this temple, which was discovered by a wood-cutter named Prem Subba in the year 2004, is a whopping 25 ft in length and 22 ft in width. It is one of the many key attractions of this beautiful town.

-Ziro is home to the interesting people of Apatani tribe, who unlike most other tribes are non-nomadic. The old women belonging to the tribe can be seen sporting facial tattoos and extraordinarily big sized nose plugs. And their this kind of get up has a back story dating back to pre-modern times.

-It is believed that decades ago women from Apatani tribe were considered most beautiful in all of Arunachal Pradesh. So beautiful that apparently men from other tribes had started to steal the Apatani women. And so the women took refuge in tattoos and big nose plugs, which made them less attractive. Today however, this custom is not practiced.

Dharnai (Bihar)- It is Solar powered!

 

4_Dharnai_solar

-With the efforts of Greenpeace India, a 100 KW solar-based micro grid was installed in the village, which now provides 24 hour electricity to homes and commercial operations.

-Having survived as many as 30 years of dark nights, Dharnai is now India’s first fully solar powered village.

Tarkarli (Maharashtra)- Has the state’s only scuba diving training centre

 

9_Tarkarli

Tarkali is increasingly becoming popular as a picturesque beach destination. The sea water is so pristine that on some clear days, one can easily see up to depths of 20 ft in the waters.

-Dolphins are a usual sighting here.

-Ramnavmi Utsav is famously celebrated in Mahaparusha temple of the village each year.

-The village has the state’s only scuba diving training centre!

There is a lot of beauty in our own home. It is about time we notice and appreciate it.

” FaceBook அடிமைகளா நாம் எல்லோரும் …” ?

உழைப்பு யாருடையது, செல்வம் யாருடையது… என்பது ஆந்திராவின் மக்கள் கவிஞரான செரபண்ட ராஜுவின் கவிதை வரி.

இந்த ஆவேச வரிகள் உழைக்கும் மக்களுக்காக எழுதப்பட்டவை. ஃபேஸ்புக் தொடர்பாக அமெரிக்கரான மைக்கேல் ரோசன்பிளம் என்பவர் எழுதியுள்ள இணைய பத்தியை படிக்கும்போது இந்த வரிகள் தான் நினைவுக்கு வருகின்றன. உழைப்பாளிகளுக்கான செரபண்ட ராஜுவின் தார்மீக கோபம் போல, ரோசன்பிளம் இணையவாசிகளின் சார்பில், உள்ளடக்கம் யாருடையது, செல்வம் யாருடையது? என கேட்டு இந்தப் பத்தியை எழுதியிருக்கிறார்.

ஹஃபிங்டன் போஸ்ட் இணைய இதழில் ஃபேஸ்புக்கை தொழிற்சங்கமயமாக்குவோம் (Let’s Unionize Facebook) எனும் தலைப்பில் எழுதியுள்ள இந்தப் பத்தியில், அவர் நாமெல்லாம் ஃபேஸ்புக் அடிமைகளா? என்று கேள்வி எழுப்புகிறார். ஃபேஸ்புக்குக்கு  மட்டும் அல்ல, டிவிட்டர் அடிமைகள், இன்ஸ்டாகிராம் அடிமைகள் என்றும் குறிப்பிடுகிறார். இந்த இணைய சேவைகளுக்காக நாம் ஓயாமல் உள்ளடக்கத்தை உருவாக்கி கொடுத்துக்கொண்டிருக்கிறோம் என்றும் அவர் குறைப்பட்டுக்கொள்கிறார்.

இந்தக் கருத்துக்கு அவர் வந்து நிற்கும் விதம்தான் கவனத்துக்கு உரியது. வரலாற்றின் இடைப்பட்ட காலமான 15-ம் நூற்றாண்டில் நிலமே பெரும் செல்வமாக கருதப்பட்டதாகவும், பெரும் நிலப்பரப்பை கொண்ட பிரபுக்களிடம் பலரும் அடிமைகளாக வேலை பார்த்தனர் என்றும் குறிப்பிடுகிறார்

சைபர்வெளி அடிமைகள்

காலம் மாறியிருக்கிறதே தவிர வரலாறு மாறவில்லை. இன்று நிலம் என்பது சைபர்வெளியாகி இருக்கிறது, அதில் நாமெல்லாம் அடிமைகளாக இருக்கிறோம், அமேசானின் ஜெப் பெசோசும், ஃபேஸ்புக்கின் ஜக்கர்பெர்கும் இணைய பிரபுக்களாக நமது உள்ளடக்கத்தைக் கொண்டு செல்வம் சேர்த்துக்கொண்டிருப்பதாகவும் அவர் குறிப்பிடுகிறார்.

ஃபேஸ்புக்கின் 100 சதவீத உள்ளடக்கம் நம்முடையது அல்லவா என கேட்கும், இதை இலவசமாக செய்து கொண்டிருக்கும் முட்டாள்கள் அல்லவா நாம் என்றும் கேட்கிறார். இதை அவர் சொல்லும் விதம் இன்னும் துடிப்பாக இருக்கிறது. தினமும் நாம் எந்த ஊதியமும் பெறாமல், ஜக்கர்பர்கின் இணைய நிலத்தில் குடியிருக்கும் உரிமைக்காக அவருக்காக உள்ளடக்கத்தை உருவாக்கி கொண்டிருக்கிறோம் என்றும் அவர் சுட்டிக்காட்டுகிறார். ஜக்கர்பர்கின் 33 பில்லியன் டாலர் செல்வமும் நாம் சேர்த்து கொடுத்தது என்கிறார்.

இதன் பிறகு அவர் சொல்லும் விஷயம் என்ன தெரியும? 20-ம் நூற்றாண்டில் இங்கிலாந்து மற்றும் அமெரிக்காவில் உள்ள தொழிலாளர்கள் தங்களிடம் உழைப்பு எனும் சக்தி இருப்பதை உணர்ந்து கொண்டு அதன் ஆற்றலை உணர்த்த தொழிற்சங்கம் அமைத்துக்கொண்டது போல, ஃபேஸ்புக் பயனாளிகள் தொழிற்சங்கம் அமைக்கலாகாதா? என்றும் ரோசன்பிளம் கேள்வி எழுப்புகிறார்.

ஃபேஸ்புக்குக்காக உழைப்பு!

நிச்சயம் புதுவிதமான சிந்தனை தான். அதற்காக ஃபேஸ்புக்குக்கு எதிராக நாம் கொடி பிடித்துப் போராட வேண்டும் என்று அர்த்தமில்லை. ஆனால், நிச்சயம் நமது ஃபேஸ்புக்  பழக்கம் பற்றி யோசித்தாக வேண்டும். ஃபேஸ்புக்கை இலவச சேவையாக கருதி மகிழ்ச்சியுடன் பயன்படுத்திக்கொண்டிருக்கிறோம். ஆனால் நமது உள்ளடக்கத்தை வைத்து ஃபேஸ்புக் விளம்பர வருவாயை அள்ளிக்கொண்டிருக்கிறது என்பதை மறந்து விடுகிறோம். நம்மை அறியாமல் நாம் ஃபேஸ்புக் போன்ற தளங்களுக்காக அடிமைகள் போல உள்ளடக்கத்தை உருவாக்கி கொண்டிருக்கிறோம்.

இந்தக் கருத்து உங்களுக்கு ஏற்புடையதாக இல்லாமல் இருக்கலாம். சமூக வலைப்பின்னலாக அது ஏற்படுத்தி தரும் பலன்களை வைத்து நீங்கள் வாதிடலாம். உண்மைதான், ஃபேஸ்புக் இணைய யுகத்தில் நட்புக்கும், தகவல் பரிமாற்றத்துக்கும்  இன்னும் பல பயன்களுக்கும் வித்திட்டிருக்கிறது. மறுப்பதற்கில்லை. பல நேரங்களில் ஃபேஸ்புக் போன்ற சேவைகள் சமூக ஊடகங்களாக செயல்படுகின்றன. எகிப்திலும் வளைகுடா நாடுகளிலும் மலர்ந்த சமூகப் புரட்சியில் ஃபேஸ்புக்குக்கும் அதன் சமூக சகாக்களுக்கும் முக்கிய பங்கிருக்கிறது. சமூக ஊடகங்களில் பயன்பாட்டுக்கு இன்னும் நிறைய உதாரணங்கள் இருக்கின்றன.

ஃபேஸ்புக் பயன்பாடு

ஃபேஸ்புக்கை நாம் எப்படிப் பயன்படுத்தப் பழகியிருக்கிறோம் என்பதுதான் பிரச்னை.  சமூக வலைப்பின்னலாக ஃபேஸ்புக்கின் ஆதார பலம் நண்பர்கள், நண்பர்களின் நண்பர்கள், அவர்களின் நண்பர்கள் என நட்பு வளையத்தை விரியச்செய்வதுதான். இந்த நட்பு வளையத்தில் எதைப் பகிர்ந்து கொள்கிறோம் என்பதும், எதற்காக பகிர்ந்து கொள்கிறோம் என்பது முக்கியமானது இல்லையா?


எல்லாவற்றையும் நிலைத்தகவலாக பகிர்ந்து கொள்வது இயல்பாக இருக்கிறது. வீட்டு விஷேசத்தில் எடுத்த புகைப்படங்களையும், சுற்றுலா பயணத்தில் எடுத்த புகைப்படங்களையும் எந்த யோசனையும் இல்லாமல் ஃபேஸ்புக்கில் பகிர்கிறோம். அதனால் என்ன வந்துவிடப்போகிறது?

ஆனால், உங்கள் தனிப்பட்ட பயணம் பற்றிய புகைப்படம், நண்பர்களின் நண்பர்களுக்கு எந்த விதத்தில் அவசியமானது என்று யோசித்துப்பாருங்கள்? உங்கள் மகனுடனோ, மகளுடனோ இருக்கும் புகைப்படம் நிலைத்தகவலாக வெளியிடுவது எதற்காக? அவற்றுக்கு காரணம் இல்லாமல் கிடைக்கும் லைக்குகளை விட்டுத்தள்ளுங்கள்.

புகைப்படங்களை நண்பர்களுடன் பகிர்ந்து கொள்வது இயல்பானது தான். வீட்டுக்கு  வரும் நண்பர்களிடமும் உறவினர்களிடமும் புகைப்பட ஆல்பத்தை காண்பித்து மகிழ்வது வழக்கமானது தான். ஆனால் நன்றாக யோசித்துப்பாருங்கள், எல்லோரிடமும் நீங்கள் இவ்வாறு செய்வதில்லை. அதற்கு ஒரு பரஸ்பர நெருக்கம் தேவை. வரவேற்பறையில் பேசிக்கொண்டிருக்கும் எல்லா நண்பர்களுக்கும் நீங்கள் புகைப்பட ஆல்பத்தை காட்ட விரும்ப மாட்டீர்கள். அதற்கான நெருக்கமும் இணக்கமும் இல்லாத நிலையில் அந்த நண்பரும் கூட அதை விரும்பமாட்டார். இதெல்லாம் எழுதப்படாத சமூக விதிகள். இயல்பாக எல்லோரும் அனுசரித்து நடப்பவை.

தனியுரிமை கவலை

ஆனால் ஃபேஸ்புக்கில் சொந்த ஊர் பயண புகைப்படங்களை பகிர்ந்து கொள்வது எந்தவகையான வெளிப்பாடு? ஊர் மாறியிருக்கிறது, விவசாயம் மங்கிவிட்டது போன்ற பொதுவான எண்ணங்களை பகிர்ந்து கொள்ளலாம். கிராமத்து மண்வாசத்தையும் பகிர்ந்து கொள்ளலாம். ஆனால் தனிப்பட்ட குடும்பக் காட்சிகளை சித்தரிக்கும் புகைப்படங்களை பகிர்வது எதனால்? உங்கள் பிள்ளைகளின் புகைப்படங்களும் குடும்பத்தின் புகைப்படங்களும் தேவையில்லாமல் இணையத்தில் எல்லா இடங்களிலும் இறைந்து கிடப்பது நல்லதல்ல.

வேலைக்கு ஆள் எடுக்கும் நிறுவனங்கள், விண்ணப்பித்தவர்கள் பற்றி தகவல்கள் சேகரிக்க சமூக வலைப்பின்னல் பக்கங்களை அலசிக்கொண்டிருக்கின்றன என்பது உங்களுக்குத் தெரியுமா? விண்ணப்பத்தில் குறிப்பிடும் தகவல்களை எல்லாம் விட ஒருவரைப் பற்றிய சித்திரத்தை அவரது சமூக வலைப்பின்னல் பதிவுகள் உணர்த்தி விடுவதாக கருதப்படுவதும் உங்களுக்குத் தெரியுமா? இன்சூரன்ஸ் நிறுவனங்கள் ஃபேஸ்புக் பதிவுகளை ஆதாரமாகக் கொண்டு செயல்படுவதாக கூறப்படுவதை அறிந்திருக்கிறீர்களா?

நேற்று நீங்கள் ஃபேஸ்புக்கில் எந்தச் சிந்தனையும் இல்லாமல் பகிர்ந்து கொண்ட தகவலும் புகைப்படமும் என்றேனும் ஒரு நாள் உங்களுக்கு வில்லங்கமாக முடியும் வாய்ப்பு உள்ளது என்பதும் தெரியுமா?

ஜார்ஜ் ஆர்வெல் சித்தரித்த கண்காணிப்பு யுகம் போல நாளை யாரேனும், ஃபேஸ்புக்கில் நீங்கள் விரோதமான கருத்தை சொல்லியிருந்தீர்களே என்று கேட்கக்கூடிய நிலை வரலாம். இது கற்பனை தான். ஆனால் நிகழாது என்று சொல்வதற்கில்லை.

என்ன செய்யலாம் ?

Meet Pratibha Krishnaiah Who works in a Village now After Leaving a Lucrative Career

India is witnessing a radical transformation where highly qualified youngsters are giving up cushy jobs to make a difference in the lives of poor people in rural areas.

Manu A B/Rediff.com tracks the success stories of some of the remarkable people who are working in remote villages to change the profile of rural India.

Pratibha Krishnaiah quit a lucrative career to help rural women in Uttarakhand.

It has been a paradigm shift for Pratibha Krishnaiah, who till last year was cozily placed, working as a software engineer in a multinational firm in Bangalore.

But these days she takes a grinding two-hour trek to reach her work place that is nestled in the Uttarakhand valley and has been trying to bring about a positive change amongst the rural women folk spread across three villages.

Pratibha Krishnaiah has been guiding women from Khetikhan, Tapni Pal and Dhat villages on how to be productive and earn money, without having to leave their families to distant towns to eke out a living.

Pratibha trains women on knitting new products

Pratibha says life in the mountains has taught her a lot and made her own life more worthwhile. Earlier even waking up early was so difficult. Now she easily gets up by 4.30 everyday and starts the day with yoga and jogging. Walking uphill to interact with the women in the villages is not difficult anymore.  “Personally, I have never felt so much happiness in my life. Living here been a great experience,” she says.

“It is really good to live with minimal income. I don’t have to worry about tax cuts neither do I have to think about good investment proposals. Money is not the most important thing in life. Though my job profile was good, I felt burnt out. I wanted to be close to nature and work dedicatedly in the villages and the SBI’s fellowship looked liked a magical opportunity. My parents thought it was a ridiculous idea to give up a good job but I convinced them to pursue my dream,” says Pratibha who is at peace now.

People in the village depend mostly on agriculture and it is a big gamble because weather plays a crucial role here. After months of hard work, when the crop is ready to be harvested, untimely rains just damage the yield which leads to huge losses. So it was important to find an alternate and steady income.

Cut off from the mainstream, the innocent villagers have little idea about the value of their products or their own capabilities. Empowering women, honing their inherent skills and finding a market for their unique products is now Pratibha’s mission.

After working for 7 years in Thomson Reuters, Pratibha realised that she needed to do something more meaningful in life. She was looking out for options to work in the rural sector when she came to know about the SBI Youth for India fellowship, which offers a 13-month stint to bring about positive changes in villages.

People in the village too thought she was crazy to give up a good city life to work in the harsh terrain that too in bad weather conditions, at a time when most youngsters in their villages were migrating to cities for better prospects.

Pratibha was captivated by the beauty and serenity of the place. But the initial days were grueling for a city-bred person like her.

“The first week was really tough. I was not used to such cold weather. I even thought I may not be able to survive there. But slowly I got acclimatised and settled well. The spirit of people is amazing and despite such tough conditions they go out to work and stay happy with meagre incomes. I realized that if you get satisfaction and peace from your work, that’s the best reward,” says Pratibha.

Once during heavy rains, the village did not have electricity for a week. Phone networks were down and they were literally cut off from the outside world. “For me it was a first experience but for the people here, it’s a way of life. They have no complaints,” says Pratibha.

 

Considering the harsh conditions, it was necessary to find an alternate source of income.Pratibha found that the women were good at knitting. These women are so good at multitasking that they will be knitting even while walking to the market carrying a big load on their head, she observed.

So she mobilised a group of 25 women to develop their skills in knitting and taught them crochet work. She provided them with elegant designs and helped them make small woollen products which have a good demand in cities.

She also trained them to make things like mufflers, shawls, small shoes, socks, hair clips and hair bands which can be made in lesser time. Pratibha then held an exhibition of these products at Bangalore and it was well received.

 

There is a good market for such products…If there is regular supply it would generate additional income for these women, says, Prathiba.

Though they are good at knitting and crochet work, they can’t give up working as labourers because it does not give them a steady income. So unfortunately these women are either toiling in the fields or working as labourers.

Partibha believes that there is so much scope for entrepreneurship here. It is a hard struggle for women who work as labourers for just Rs 20-30 a day. Most of them drop out from school or study till tenth as the government offers them Rs 50,000 for their marriage expenses if they study till tenth grade.

Pratibha plans to establish a market for their products in cities so that they have a steady income. She also has plans to set up a small scale industry, which can be run by these enterprising women.

Women on an average spent about 20 hours across a period of 1-2 weeks to knit a sweater which they sell for just Rs 250. I have now trained them to make clips which takes just 15 minutes to make and can be easily sold for Rs 15 a pair. A muffler which takes lesser time to stitch can be sold for Rs 300, so it saves them a lot of work and time,” says Pratibha.

NGOs like BAIF are a great support to the people here. Many of them have taken initiatives of creating self help groups for doing knitting work but it can be expanded on a large scale if all the women work together. They can make a better income with a collective effort, believes Prathibha.

The villagers are very simple people, not at all ambitious and most of them are ignorant about their own potential. They need a constant backing and support to get them out of the drudgery to better lives,” says Pratibha who wishes to continue supporting them even after the fellowship is over after 6 months.

Agriculture being a labour intensive job, people spend so much of time in the fields yet it ends up giving negligible returns at times. The village needs to have co-operative societies and government assistance to regulate buying and selling of agricultural produce. Most of the farmers go to the nearby town to sell their products at throwaway prices and later small shops from this village buy it from those traders, who sell it at much higher prices. So ironically people in the village end up paying more for their own produce.

“I live with an old couple here – Madhavanand and Bhagyalakhsmi. Both of them are above 70 years. I have seen the kind of hardships they go through to get the farming done. This year their entire barley cultivation has yielded nothing as rains wreaked havoc. I really wish to bring an end to such suffering. If they have an alternate means of liveliehood or have better marketing for their agricultural products, these hard working people can lead better lives,” explains Pratibha.

Most families make just Rs 2,000-3000 a month. Some months they just don’t earn anything.

Organic farming is also good practice here. Unfortunately, even farmers like Mahesh Chander who has been a crusader of organic farming is yet to get a certification for his farm. He has even made organic pesticides with medicinal plants. There is no support from the government to support such dedicated people,” says Prathibha who wants to focus on organic farming as well in future.

Pratibha also plans to starts an organic farm, go back to natural ways of farming and set up model farms. She believes that these are just small steps. But if more people come forward to help in rural development, we can really help people and build a sustainable economy.

Mumbai Teen Lights up Lives in Assam villages…

Dhruvraj Bhartia along-with Jyotirmoy Chatterji, co-founder of Project Chirag, singlehandedly set up 165 solar lamp units in the four villages

Dhruvraj Bhartia, a 17-year-old teenager from Jamnabai Narsee School in Mumbai, chose to use his summer vacation differently and decided to reach out to people of remote villages in Assam by providing solar lights where there was no electricity so far.

His dream is finally turning to reality as Nezone Biscuits, Tezpur agreed to sponsor the solar units in four villages — Kamarpathar, Sirajuli, Bordubi and Habigaon near Dhekiajuli — where there was no electricity.

Project Chirag

Since 2010, Dhruvraj has been a senior youth ambassador with Project Chirag, an initiative of Chirag Rural Development Foundation, a Mumbai-based NGO.

Project Chirag, started by a group of college students, is involved in providing solar lighting to villages deprived of electricity and in the last five years has helped more than 45,000 villagers in six states of India.

For the last two days, Dhruvraj along-with Jyotirmoy Chatterji, Co-Founder of Project Chirag, single handedly set up 165 solar lamp units in the four villages.

“Renewable energy is the way forward in rural India, 25 per cent of India is seeped in poverty, if each one of us able citizen could contribute towards benefitting one family, we truly could develop an inclusive economy,” Dhruvraj said at a meeting at one of the villages today.

Dhruvraj and Jyotirmoy also explained to the villagers how to use the lights and maintain it over a period of time.

The team looks forward to scaling up the initiative further and lighting up more villages in remote parts of Assam with support from corporates, individuals and in partnership with educational institutes, he said.
