Top 10 Clever Google Search Tricks



SEARCH

Top 10 Clever Google Search Tricks

Whitson Gordon , Gawker Media
Google is a more powerful tool than most people realize. You can get much more refined searches with Google's built-in tools, advanced operators, and third-party extensions. You can also use it for some pretty cool stuff if you know the right tricks. Here are 10 of our favorite lesser known tricks and features.

10. Use Google to Search Certain Sites

If you really like a web site but its search tool isn't very good, fret not-Google almost always does a better job, and you can use it to search that site with a simple operator. For example, if you want to find an old Lifehacker article, just type site:lifehacker.com before your search terms (e.g. site:lifehacker.com hackintosh). The same goes for your favorite forums, blogs, and even web services. In fact, it's actually really good for finding free audiobooks, searching for free stuff without the spam, and more.

9. Find Product Names, Recipes, and More with Reverse Image Search

Top 10 Clever Google Search Tricks
Google's reverse image search is great if you're looking for the source of a photo, wallpaper, or more images like that. However, reverse image search is also great for searching out information-like finding out who makes the chair in this picture, or how do I make the meal in this photo. Just punch in an image like you normally would, but look at Google's regular results instead of the image results-you'll probably find a lot.

8. Get "Wildcard" Suggestions Through Autocomplete

Top 10 Clever Google Search Tricks
A lot of advanced search engines let you put a * in the middle of your terms to denote "anything." Google does too, but it doesn't always work the way you want. However, you can still get wildcard suggestions, of a sort, by typing in a full phrase in Google and then deleting the word you want to replace. For example, you can search for how to jailbreak an iphoneand remove one word to see all the suggestions for how to ____ an iphone.

7. Find Free Downloads of Any Type

Top 10 Clever Google Search Tricks
Ever needed an old Android app but couldn't find the APK for what you were looking for? Or wanted an MP3 but couldn't find the right version? Google has a few search tools that, when used together, can unlock a plethora of downloads: inurlintitle, and filetype. For example, to find free Android APKs, you'd search for -inurl:htm -inurl:html intitle:"index of" apk to see site indexes of stored APK files. You can use this to find Android apps, music files, free ebooks, comic books, and more. Check out the linked posts for more information.

6. Discover Alternatives to Popular Sites, Apps, and Products

Top 10 Clever Google Search Tricks
You've probably searched for comparisons on Google before, like roku vs apple tv. But what if you don't know what you want to compare a product too, or you want to see what other competitors are out there? Just type in roku vs and see what Google's autocomplete adds. It'll most likely list the most popular competitors to the roku so you know what else to check out. You can also search for better than roku to see alternatives, too.

5. Access Google Cache Directly from the Search Bar

Top 10 Clever Google Search Tricks
We all know Google Cache can be a great tool, but there's no need to search for the page and then hunt for that "Cached" link: just type cache: before that site's URL (e.g. cache:http://lifehacker.com). If Google has the site in its cache, it'll pull it right up for you. If you want to simplify the process even more, this bookmarklet is handy to have around. It's great for seeing an old version of a page, accessing a site when it's down, or getting past something like the SOPA blackout.

4. Bypass Paywalls, Blocked Sites, and More with a Google Proxy

Top 10 Clever Google Search Tricks
You may already know that you can sometimes bypass paywalls, get around blocked sites, and download files by funneling a site through Google Translate or Google Mobilizer. That's a clever search trick in and of itself, but just like Google Cache, you can make the process a lot faster by keeping a few URLs on hand. Just add the URL you want to visit to the end of the Google URL (e.g.http://translate.google.com/translate?sl=ja&tl=en&u=http://example.com/ and you're good to go. Check out the full list of proxies, along with bookmarklets to make them even easier, here.

3. Search for People on Google Images

Top 10 Clever Google Search Tricks
Some people's names are also real-world objects-like "Rose" or "Paris." If you're looking for a person and not a flower, just search for rose and add to &imgtype=facethe end of your search URL, as shown above. Google will redo the search but return results that it recognizes as faces!

2. Get More Precise Time-Based Search Results

Top 10 Clever Google Search Tricks
You've probably seen the option in Google that lets you filter results by time, such as the past hour, day, or week. But if you want something more specific-like in the past 10 minutes-you can do so with a URL hack. Just add &tbs=qdr: to the end of the URL, along with the time you want to search (which can include h5 for 5 hours, n5 for 5 minutes, or s5 for 5 seconds (substituting any number you want). So, to search within th past 10 minutes, you'd add&tbs=qdr:n10to your URL. It's handy for getting the most up-to-the-minute news.

1. Refine Your Search Terms with Advanced Operators

Top 10 Clever Google Search Tricks
Okay, so this isn't so much a "clever use" than it is a tool everyone should have in their pocket. For everything Google can do, so few of us actually use the tools at our disposal. You probably already know you can search multiple terms with AND or OR, but have you ever used AROUND? AROUND is a halfway point between regular search terms (like white teeth) and using quotes (like "white teeth"). AROUND(2), for example, ensures that the two words are close to each other, but not necessarily in a specific order. You can tweak the range with a higher or lower number in the parentheses.
Similarly, if you want to exclude a word entirely, you can add a dash before it-like justin bieber -sucks if you want sites that only speak of Justin Bieber in a positive light. You can also use this to exclude other parameters-like excluding a site you don't like (troubleshooting mac -site:experts-exchange.com). Check out our guide to tweaking your Google searches for more of these tips, and you can also find a pretty solid list over at weblog Marc and Angel Hack Life. Search on!

Intel vs AMD: which processor is best?

Intel vs AMD: which processor is best?
Your CPU is your PC's brain, so make sure you choose the right processor
By Mike Williams





Buying a desktop computer can be a lengthy process involving many complex decisions, but none come with quite as much jargon as figuring out the best CPU.

Before you know it, you're drowning in talk of cores and clock speeds, socket types and memory controllers, Bulldozer, Piledriver and more.

While you'll need to consider at least some of these issues, there's an easier way to approach your purchasing problems. And that's to ignore the technical detail, just for the moment, and focus first on a more fundamental question: Intel vs AMD, which processors are the best for you?

You'll probably find that answering this is much more straightforward. And once you've made your choice, many other decisions about your new PC will fall into place, saving you plenty of time.
Intel vs AMD: Intel CPUs

If you're after performance above else (and you can afford the price tag) then Intel processors are generally a good choice. As our "Best CPU" benchmarks showed, strong single core performance means they generally outperform the competition.



The difference can be marginal, though. It may be even less significant if you're planning to spend time overclocking your chosen CPU, or if your target applications make good use of multiple cores - especially as AMD chips are generally priced much lower, which means you can sometimes get extra cores for less money.

Even opting for Intel's very latest Haswell CPUs won't deliver a major leap forward in desktop power, unfortunately. Haswell processors come with the same default clock frequencies as their predecessors, the same four cores (with the mainstream sockets). Performance might edge up by 10 per cent or so, but you're most probably not going to notice any difference.

It's not all bad news, of course, particularly if you're interested in mobile computing. As ourguide to Haswell explains, Haswell CPUs have new sleep states and enhanced power management which promise a major leap forward in battery life.

For instance, you should be able to leave a Haswell system on active standby, regularly grabbing emails, downloading social media updates and more, for a whole seven days on a single charge: very impressive.



But on the desktop, even the top-of-the-range Intel Core i7-4770K really doesn't deliver much new (beyond requiring another new socket, meaning you can't drop it into an existing system). As our Intel Core i7-4770K review points out, it's "just barely any better than the processor it replaces", not good news when it also comes with a significant price premium - as we write, it's priced at US$350 (about AU$380, £228).



Intel's latest technologies could make a real difference to mobile devices, then. But if you're looking for a desktop solution then the company's older Ivy Bridge products currently deliver the best mix of price and performance, and that's where its best deals are still to be found.
Intel vs AMD: the AMD competition

If you're wondering how it is that Intel can get away with desktop processors which have changed so little in previous years, the answer is simple: they just don't have much competition.

Partly that's because AMD has been trailing behind Intel for some time now, especially when it comes to desktop performance. While the company has promised a lot, they've singularly failed to deliver, and just can't compete with the best that Intel has to offer.



When there are new products, then like Intel, AMD are generally more focused on the mobile space. As we explained in our report on AMD's new A4, A6, A8 and A10 CPUs, for instance, the headline news is the 21 per cent claimed increase in graphics speed. More general desktop performance only edges up by perhaps 8 per cent.



This isn't quite the end of the story, though. While AMD's desktop CPUs generally lag a little behind the Intel competition, there are a few exceptions. Overclocking can reduce the gap still further, and low prices ensure that there are still some great AMD deals to be found.

What's more, AMD has a particularly interesting new technology, in the shape of its Kaveri chip. This uses a heterogeneous system architecture (thankfully better known as HSA) to not only combine a CPU and GPU in a single die, but also allow both processors to access the same areas of memory without waiting for the other to finish first.

The project has some other promising features, too, and while the end result might not immediately overtake the best Intel CPUs, the first Kaveri releases - due very soon - could bring back some real and much-needed competition to the desktop CPU market.
Intel vs AMD: which is best?

We've looked at the two product families, then - but which is best? It all depends on what you're looking for.

At the low end of the market, where price matters above all else, AMD offers some good deals. The AMD A4-5300 is available for under US$50 (you can buy an entire Socket FM-2-based PC for about US$300), and while its specifications don't impress - two cores only, a mere 1MB cache - if you'll mostly be using the system for email and browsing then it'll serve you very well.

Move up the price range and Intel begins to enter the picture with a product like the Intel Core i3-3225: dual core, 3MB cache, US$134 (about AU$146, £87). And if you prefer Intel and don't need a great deal of power then that might just about be enough.



Once again, though, AMD offers better value. The Socket AM3-based AMD FX-4130 is a particularly good deal: it's a similar speed to the Intel Core i3-3225, but the two extra cores will help with multi-threaded applications, and at US$99.99 (about AU$109, £65) it's something like 25 per cent cheaper than Intel's offering.

If anything the AMD FX-6130 is even better, delivering 6 cores, with overclocking potential of 5GHz, and still at a very good price.

Excellent single core performance does mean that regular desktop systems will generally be better off with an Intel processor, though. If you don't need the flexibility of manual overclocking then we'd opt for the US$195 (about AU$213, £127) Intel Core i5-3470, which offers both excellent single and multi-threaded performance. Meanwhile, the US$235 (about AU$256, £153) Core i5-3570K is a speedy (and very overclockable) quad-core product with 6MB cache which still performs well today.



Moving beyond this price level won't make a great deal of sense for the average user, as you simply don't get the extra performance to justify the extra cost. But if you have the money, then the Ivy Bridge Intel Core i7-3770K still delivers quality performance, hyperthreading and a fully unlocked CPU multiplier.

This could all change quite soon, of course, particularly with AMD's Kaveri technology. Can it help to bring some real competition back to the desktop CPU world? Just keep an eye on our reviews and news pages and we'll keep you up-to-date.

Electric Bus Charges in Just 15 Seconds

Electric Bus Charges in Just 15 Seconds

New system frees trolleys from cumbersome wires.

Web2Carz Staff Writer
Zero emissions transportation solution.
Zero emissions transportation solution.



electric bus
TOSA electric bus
Electric transportation systems are one step closer to becoming integrated into urban populations.

Current battery technology has limited trolleybuses, necessitating that they stay connected to a cumbersome web of cables at all times in order to remain charged throughout the day. However, this may all be changing soon after a successful pilot operation recently concluded in Geneva, Switzerland, using a cable-free electric bus system called TOSA.
“The batteries on-board the buses have twice the energy of an electric car battery, but are small enough to fit on the roof.”

Researchers at the Swiss Federal Institute of Technology (EPFL) have developed an electric bus that can recharge itself in just 15 seconds at a stop in what’s being called “flash” recharging. It’s a green infrastructure alternative that provides buses that are not only zero emissions, but are also able to roam free of cable tethers. These overhead wires can be a major inconvenience to the residents of buildings where the wires are attached. And TOSA buses are able to adapt their routes in the case of an accident or heavy traffic.

Bus battery

The batteries on-board the buses have twice the energy of an electric car battery, but are small enough to fit on the roof. Once a bus pulls into a charging station, a robotic arm on the roof zips up and engages, giving the battery 15 seconds of recharging time — about the same amount of time it takes passengers to board and exit the bus. It gives the bus enough energy to get to the next recharging station on the route, though the researchers haven’t specified how many miles the vehicle would be able to travel or how far away the next charging station would need to be.

The researchers are still investigating this very question, trying to create a framework of necessary charging stations that would need to be installed in order to keep the network of buses running reliably and on-time. 

These recharging stations would be installed along the normal bus route, and would ideally be a cost-saving investment that reduces the amount of infrastructure needed versus the traditional method for powering trolleys. The other question researchers are factoring into their design is what happens when two bus routes converge, seeing as the charging station can only charge a single bus at a time.

Su-Kam UPS

Su-Kam has introduced a truly innovative inverter model ‘Falcon Plus’ in the market ( though I hate this marketing kind of words in a product review, I just can’t avoid the word ‘innovative’ in this review, Yes, it is truly innovative)

When we took this product for testing and comparing it with other best-selling inverter models in the market, we were surprised to see the results and other special features of sukam Falcon Plus.

Sukam has already got a product called ‘Falcon’ Home UPS, which is doing well in the market. But this one ‘Falcon Plus’ is pretty much advanced than its predecessor.
Sukam Falcon Plus
This is going to be a long post; those want to read insights about Falcon Plus can continue :)

# Falcon Plus – Range

Su-Kam Falcon Plus Pure sinewave Inverter is available in following range
Falcon Plus 700 VA – single battery inverter
Falcon Plus 900 VA- single battery inverter
Falcon Plus 1100 VA – single battery inverter
Falcon Plus 1600 VA – Double battery inverter
(Note: Sukam Falcon Plus 1050 VA  (Old Version) is also available in the market. Su-kam has upgraded this model to 1100 VA and the 1050 VA model has no Battery charge selection DIP switch.)

# Su-Kam Falcon Plus – Test Results

Actually we don’t care about, what the company claims about the product, in its product manual. We want to test it out.

We compared Sukam Falcon Plus with Luminous Zelio, Luminous Eco Volt and Microtek Pure sine wave inverter models with a highly sophisticated testing device.

Results clearly indicated some solid difference between other pure sine wave inverters and sukam Falcon Plus. We list some important points here,
  1. Advanced Battery charging Technology
  2. Battery life enhancement
  3. Deep discharge Protection
  4. Appliance Safety features
  5. Compatibility with all size batteries (18 Ah to 200 Ah)
  6. High quality internal components
  7. Big Difference in back-up
  8. Highly compatible for Solar

# Why choose Falcon Plus?

Advanced Battery charging technology

Whether you go high budget or low budget battery for your inverter, we would recommend Su-kam Falcon Plus for better battery management and battery life enhancement.

In our observation, with Falcon Plus, we could expect extra battery life from 6 months to 1 year for a normal deep cycle inverter battery.

# How Falcon Plus enhances the battery life?

Falcon Plus senses the battery outside temperature and adjusts the Boost Voltage
battery charge state
falcon_plus_temperature_sensor
Falcon Plus uses Automatic temperature compensation (ATC)

Unlike other inverters in the market, Falcon Plus has a temperature sensor cable which comes with the inverter package. We need to connect the sensor cable to the back panel of inverter and place the other end of the cable close to your battery. In this way Falcon Plus senses the outside temperature precisely.

Most of the people in this industry are aware of the truth that a deep cycle battery will perform well under 25 degree Celsius. But unfortunately in India we experience extremely hot weather during summer. Sometimes the temperature crosses 40 degree Celsius, which is unfavorable condition for charging an inverter battery.

In such condition we cannot pump the same high voltage in to the battery for charging. It would harm the battery permanently.

So, the inverter should adjust the boost voltage according to the outside temperature. Unfortunately most inverter in the market never does this adjustment and slowly they cause damage to your expensive tubular battery.

Just Like your Air conditioner, Falcon plus senses the temperature and adjusts the boost voltage according to that.

Thanks to 4th generation Micro Processor and ATC technology.

In our experience, we have seen many number of cases in which brand new tubular battery gets spoiled by faulty inverter which gives continuous charge to the battery during high temperature.

# Less frequent water topping

Most people don’t know how to add distilled water to their inverter battery; they mostly rely on any local battery shop guys or electricians.

But sometimes, people simply forget to top-up their battery periodically which leads to premature battery failure.

To avoid this situation, better we buy a smart inverter that doesn’t heat up our battery with excess charging during hot weather. Then there will be no frequent water loss.

Falcon Plus inverter’s ATC technology is giving some hope and we expect this will eliminate the problem of frequent water topping the battery.

Anyway, you will need to add distilled water periodically, but the frequency will come down.

Don’t forget to do that!

# Deep Discharge Protection

deep_discharge_protection_falcon_plus

Deep discharge is one of the main problems we face with batteries. When we discharge a battery below 10.5 V, it is just like killing your battery. But it is your inverter’s responsibility to protect your battery with setting up a perfect cut-off voltage. Failing to do this will result in permanent damage to your battery.

Almost all inverter manufacturers claim that their inverter has deep discharge protection, but how many of them are genuine? We don’t know!

We tested Falcon plus inverter’s ability to protect the battery from deep discharge.

And the test results were good. They are genuine!


Falcon plus comes with one more extra facility of choosing the cut-off voltage ourselves. There is a DIP switch to choose the cut-off voltage.

You could

Select 10.5 V for better backup (or)

Select 11 V for better battery life (back up will be reduced in this mode)

No other inverter model in this range has this kind of facility, one more step towards innovation, Good!

We recommend to setup 11V back-up cut for better battery life.

If you experience long and intermittent power shedding problem, you should use 10.5V backup cut setting for better battery backup.

# Soft Start Technology and Appliance Safety

This inverter is equipped with soft start technology, which slowly raises the output voltage to ensure the appliance safety.

Pretty useful facility for using sensitive electronic gadgets with inverter backup.

# Automatic Bye-pass switch

Falcon plus inverter has an automatic bye-pass switch arrangement, which is very useful in case of any battery problem of any other minor issues with battery or inverter.

We don’t need to manually bye-pass the line.

# Compatible with local Generators

Company claims that Falcon plus is compatible with local generators. Most other inverters don’t work with local generators.

# Better Micro Processor

28 pin micro controller

falcon plus 48 pin micro processor

We noticed one important difference that the new Falcon plus inverter is equipped with 44 pin microprocessor, which usually cannot be seen in other Home UPS systems.

Normally Home UPS systems are equipped with 28 pin micro controller with limited functionalities.

But in this Falcon Plus Model, Su-Kam uses the most advanced 44 pin microprocessor and it provides some extra benefits and smart features which we have not seen before in Home UPS systems.

# Compatibility with Solar panels

falcon_plus_solar_compatible_inverter

We tested it with solar panel and solar charge controller and satisfied with the results.

It is 100% compatible with solar panels, which means we can convert it to advanced hybrid solar inverter by adding solar panels and automatic solar charge controller to it.

In case you plan to buy it as a package, we recommend to buy Sukam solarcon ‘solar’ charge controller which is 100% compatible with falcon plus.

# How Sukam Falcon Plus enhances Battery Backup?

falcon_plus_DT_6S
We noticed one advanced feature in falcon plus that eliminates the need for bench charge and De-sulphation for batteries, which could be done only in battery service centers.

In the long run, normally inverter battery plates will be covered by sulphate cystal, which stops the battery from operating to its full potential.

In Falcon Plus, Sukam Introduces a 6 stage charging Technology which removes the sulphate cystal formation on the battery plates which ensures optimum battery performance and prolong battery backup.

This is very useful feature as we cannot frequently carry our jumbo sized battery to the battery service center for de sulphation.

# Full Battery charge with 90 V

In india, we cannot guarantee perfect power supply in every location. In most areas we face low voltage problem and we don’t even get enough voltage to charge our inverter battery.

A typical inverter will require minimum 130 volts to charge the inverter battery to its full capacity.

Sukam claims that Falcon Plus will require only 90V to charge the battery to its full capacity, which is very useful for consumers with low voltage problem.

# Comaptible with Desktop PC (Switch Over time – 8 Milli seconds )

Switch over time of a typical pure sine wave inverter in the market – 13 Milli seconds

Switch over time of Sukam Falcon Plus Home UPS – 8 MIlli seconds

Which is pretty much compatible for operating desktop PC’S without rebooting problem during power cuts.

We recommend this for browsing centers, Computer centers and educational institutes.

No need to buy separate UPS for your desktop PC.

# Wide Range of Battery support (18 Ah to 200 Ah)

falcon_++_back_panel

We personally love this Feature which is truly innovative.

Su-Kam enables the facility of connecting a tiny battery of 18 Ah to a 900 va or 1100 VA single battery inverter.

Connecting a small battery to a big inverter is not a big deal here, but sukam falcon plus has an option to set up the charging current for small batteries, which is really a big deal.

Yes, it has a DIP switch at the back panel where we can setup the charge current preference for batteries from 18 Ah to 200 Ah.

This facility is really a boon for end users those who want very little back up time and don’t want to spend excess amount of money in buying 150ah tall tubular batteries.

Now they can operate their gadgets with 900 VA inverter and 25 or 50 AH batteries according to their requirement.
Caution: Unless you are familiar with this DIP switch settings, Please avoid playing with switches.

# Some Questions to Su-Kam about Falcon Plus

Though we have listed out all positive sides of Sukam Falcon Plus, we also have few questions about some glitches that we found in falcon plus.

Sukam Falcon Plus inverter has no LCD display, which could be very useful in monitoring battery state and remaining backup hours.

The DIP switch at the back panel provides lot more access for an end user to control the battery charging scenario of the inverter.

But more than 90% of end users don’t know how to operate this switch. What happens if they select high voltage setting for a low power battery like 25 Ah battery. It would result in battery failure.

The advanced facility which is supposed to be a Boon would become a curse to that particular user.

We strongly recommend Su-Kam to put a plastic cap on this DIP switch at the back panel and limit the access to trained professionals only.

Also when we recommend battery below 60 Ah, we need to tell the customer that it should be a deep cycle battery, otherwise people will go for cheap automotive batteries, which would not last long for inverter applications.

Why 700 VA, 900 VA and 1100 VA models don’t have MCB at back panel?. MCB is provided only in 24V double battery inverter model Falcon Plus 1600.

Product is not available online

# Availability

For now, Falcon Plus is not widely available with all su-kam dealer outlets throughout the country.

I believe, in three months it will be available on all online stores and su-kam dealer outlets.

In metros, Falcon plus is already available in selected dealer outlets.

# Price point of Falcon plus

Price point of Su-Kam falcon plus is on the higher side. But we clearly understand that such an innovative product will not come for a cheap price.

For now, we can give guideline price of Falcon plus for our readers.

Simple idea to guess the price falcon Plus

A 900 VA falcon plus inverter would cost 1000 rupees more than a normal 900 VA pure sine wave in the market.

Which means

Luminous zelio 900 VA – Rs.4500

Falcon Plus 900VA would cost around Rs.5500 to 6000.

(In some states, price would be more than Rs.6000, which depends on the transport cost and tax)

# Conclusion

Undoubtedly, Sukam Falcon plus is the most advanced model in the Home UPS segment. Even though it is little expensive compared to other models in the market, it is worth to go for Falcon Plus if you need the best inverter in the market.

Hope this long Review Helps! We will come up with more details about falcon plus and comparison chart with other inverters. Also best battery combination ideas for Falcon plus.

New ISRO satellite will revolutionise Internet in India

New ISRO satellite will revolutionise Internet in India. Read how

"This will be a technology that will eliminate cables and will be ideal for smart cities that are being planned in the country," said Tapan Misra, director, SAC, a crucial arm of ISRO.


An entertainment-cum-internet revolution is on the anvil in India. The Indian Space Research Organisation (ISRO) is building a massive 4000-kilogram communication satellite at it’s Ahmedabad-based Space Applications Centre (SAC), that will eliminate the use of cable wires, and connect televisions in Indian homes through a high-speed wireless service.

The under-construction GSAT-11 satellite will also integrate the internet and entertainment like never before. “We are building a communication satellite that will be equivalent to 150 transponders and will transmit data at 10 gigabytes per second. This satellite will bring about a societal transformation in the way we entertain ourselves at home,” said Tapan Misra, director, SAC, a crucial arm of ISRO, that has been behind the success of projects like Chandrayaan and Mangalyaan missions.

“This will be a technology that will eliminate cables and will be ideal for smart cities that are being planned in the country,” he added.

In 2009, Government of India had approved the development of GSAT-11, which is touted to be one of the largest Indian communication satellite. GSAT-11 has a mission life of about 15 years.

“It will be a four-tonne satellite. We are very proud of this project at SAC. The GSAT-11 will not only link all the towns and villages in this country with quality high-speed Wi-Fi service, it will also integrate internet and television services. It will not only revolutionise entertainment, it will also provide a quantum jump to the entertainment industry,” said Misra about the Internet-TV boom that is waiting to happen in the country in the near future.

The geostationary communications satellite which has four antennas, each with a diameter of 2.8 meters is currently undergoing flight modelling at SAC. “We plan to launch this satellite by the middle of next year. Once this satellite is in space, one can watch entertainment channels or surf the internet on their televisions. In fact it can be used for all kinds of data transmission.”

According to the ISRO scientist who is also known as the “Radar Man” for his work on Synthetic Aperture Radar (SAR), this under-construction satellite will transmit data to “local Wi-fi towers”, which in turn will beam the signals to a “dongle-type” of instruments, connected to the television.

NISAR Mission

Meanwhile, SAC which is a part of the NISAR (NASA-ISRO SAR) mission – a joint project between NASA and ISRO – has completed the baseline design review of the payload that will help study the hazards and global environmental change.

“This Synthetic Aperture Radar (SAR) has two major parts: the L-band and the S-band. While NASA will provide the L-band, we at SAC is building the S-band. This mission will bring in a paradigm shift in the remote sensing. It will be able to observe and measure even one millimeter of surface deformation on the earth’s crust occurring due to earthquakes, volcanoes, landslides, ice-sheet collapses, movement of glaciers, and others,” Misra remarked about the mission which is expected to be launched

Shiva Ayyadurai on inventing email and the backlash that followed

‘This curry stained Indian should be beaten and hanged': Shiva Ayyadurai on inventing email and the backlash that followed



I first heard of Shiva Ayyadurai while randomly scrolling through Facebook. A news article from Huffington Post appeared on my newsfeed, mentioning Shiva Ayyadurai as the inventor of email and honouring him for his achievements on the thirtieth anniversary of email. A quick google search produced another interesting piece, again from Huffington Post, which stated how two big American corporations-Raytheon and BBN- ran a sustained PR campaign to discredit and malign the brown teenager from Newark, New Jersey who was the true inventor of email.
yourstory_VA_Shiva_Ayyadurai_InsideArticle
In postcolonial India where we are quick to claim and glorify the slightest recognition from the West, I was baffled at how I had not come across his name before; especially given the magnitude of this achievement. For Ayyadurai allegedly invented email when he was only fourteen. The rest of his life is glittery with a vast array of entrepreneurial achievements (uncontested ones) from earning four degrees at MIT to founding Echo Mail,revamping the US Postal system and many more.
I saved both the articles to Pocket and forgot about them for a few days. When I tried to read them later, they weren’t to be found. An exhaustive search around the internet later I learnt that all the pieces hailing Ayyadurai as the inventor of email were taken down after a flurry of readers protested this to be categorically false. That honour instead went to American inventor Ray Tomlinson. Any search for Shiva Ayyadurai yielded three kinds of results:his recent marriage to Hollywood actress Fran Dreschertorrents of racial and other abuse deeming him to be a liar and a fraud and Ayyadurai’s own slew of registered domains.
It was difficult to gauge the authenticity of his claims from either the trolls or his own websites. Confused, I reached out to him for an interview and he obliged. But a lengthy conversation later, my confusion has not abated much. Rather than endorsing or criticizing his claims (which this author anyway has no authority to do), this interview is an attempt at opening up legitimate avenues of conversation where we can discuss, critique and opine coherently and with dignity- something the American media has largely failed to do and our Indian brethren have not expressed much interest in either. He says, “The main contention against me is that I am a self-promotional businessman. I am an internet entrepreneur. What does that have to do with the material facts of who invented email?”
We welcome your thoughts in the comments below. Please note that here we discuss only the contentious email issue. A more comprehensive conversation on his life, education and other achievements is forthcoming next week.
You were close to dropping out of school when your mother introduced you to Les Michelson (scientist at University of Medicine and Dentistry of New Jersey, under whose tutelage Shiva says he invented the email.)
Yes. I was fourteen years old at the time.
What was going on your mind when you were fourteen? 
In India I came from a family of farmers. My grandmother was a farmer. My mother, despite coming from an ‘untouchable’ lower caste family, worked impossibly hard to educate herself. My father grew up in the war and did not learn to read or write till he turned eleven. When we moved to the United States in 1970 at the age of seven I was keen to do well. Every time I went to India I realized how fortunate I was to have been given the opportunities I had, especially given where I came from. I knew I was not doing well for me but for so many who had sacrificed so I could be here. From then on I was motivated to change the world.
How did the idea for creating the email come about?
Imagine the world in 1978. No PC’s, no smartphones and no laptops. The ordinary person did not have access to the computer. Those who got to use it were highly technical people- system analysts, programmers, etc. and they too used it only for data processing.
For me email was not a technical person sending another technical person a message. It was the entire system and it was designed for the ordinary end user. A doctor, a dentist or a secretary. So they would move from a typewriter to the computer terminal. That was what made email revolutionary.
Before Steve Jobs created the computer, people had to build their own computers. They had to buy the parts separately and assemble it. That’s what made the Mackintosh revolutionary. It was accessible to millions of people. Email made the computer accessible to millions of people and that’s what I invented.
How did you come upon the idea?
The idea was to make communication accessible for the ordinary end user. It was not just making text messaging accessible. That’s what they were doing. We had about a hundred different features. You see a secretary would not move to email unless it had all the features she was used to. She was used to seeing an inbox, outbox, address book and a trash folder. She was used to getting a return receipt. All these features needed to be interconnected. Email is a system of interconnected parts. It was like creating an engine.
One of the most common criticisms levelled against you is that you don’t acknowledge that your invention was built on the works of those who came before you in the sixties, especially individuals like Ray Tomlinson and organizations like ARPANET. How much of inventing the Email was original and what was based on prior works?
You have to understand the politics at work here. Over here is the military, the private industry and academia. What they were doing in the sixties and the seventies was trying to send a message from Point A to Point B for soldiers in the battle field. In 1978, at the age of fourteen, I had no access to that technology, did not use any of their parts. And this is what needs to be brought out. We didn’t need any of their stuff to bring out the Email. We didn’t even need the internet.
The early email systems, from the one I built to all the way up to 1993 and you can read up on the facts yourself, did not use the internet. They were built around local area networks. In one office we literally ran ether net cords and set up our computers. We were not using their networks and protocols at all.
They want the world to think that you need the military. That the military industrial complex creates great technologies. The reason there is so much anger and backlash is because we, as a public, have been taught to believe that our tax dollars fund the defence department. The defence department does research and once in a while we get GPS. We get Velcro. We get email. It’s a way of justifying all this spending on the military.
In 1978 I did not use even a single of their components. I didn’t need it.
Philo Farnsworth, a fourteen year old boy from a small town in Idaho, invented the television. They attacked him just as viciously. We are changing the narrative here. What we are saying is that a small kid from India or Idaho could invent life changing things. We don’t have to spend billions funding the military. The military industrial complex has convinced us that we should fund them because they are the big innovators. Only a white man could create something like that. A dark skinned kid in Newark, New Jersey-the thought of him creating the email is like an explosion to these people. That’s why they have to pull down articles. You go my Wikipedia page and run through the list of previously published articles discussing my works and achievements. All the links have been destroyed. I have been a scientist and an inventor for forty years of my life. The idea is to not only destroy the accurate account of events but also to destroy me.
The reason is not about me. It is about preserving that military industrial complex where we go kill people in the Middle East and bomb people and because of them great innovations come. It’s not true. The email was invented through collaboration. But it was not of the military but through the collaboration of good teachers, my parents, Michaelson and the support of a small local environment. And that is revolutionary. If people know that the email and television were created by fourteen year old kids, then they realize they don’t need to spend enormous sums backing the military. And that’s what they are afraid of.
Huffington Post ran an article about myths surrounding the invention of email that has since been taken down. For purposes of posterity, can you give a rundown of some of those myths?
The first myth was that the ARPANET created email. Absolutely false. What they did was electronic text messaging. The ARPANET was working on battlefield communications via telegraph. It was a very rudimentary system. David Crocker himself, in December 1977, wrote an article saying, “No attempt is being made to emulate a full-scale, inter-organizational mail system.”
The second myth was that Ray Tomlinson invented email and that he sent the first email message. Ray Tomlinson did not write fifty thousand lines of code. He wrote may be fifteen twenty lines of code. He took an old program, manipulated it a little bit and he used the ‘@’ symbol to designate two computers. That’s not email. That’s not inbox outbox folders. But BBN and Raytheon launched a massive PR campaign to discredit my work. They wanted to build their brand. Being known as the inventors of email would give them tremendous advantage towards winning billions of dollars of security contract.
The frankly racist articles put up at Gizmodo and Techdirt claim that RFCs were emails. RFC’s are meeting notes. It meant Request for Comment. In those days you had a meeting, a bunch of guys were at the table and they would write out the meeting notes. They would send the meeting notes to everyone involved. RFCs are not a computer program. They are not any type of a specification for user interface.
It’s also claimed that the CTSS was email. CTSS was the system that was developed at MIT and it was essentially an early blog or wall post at best. They called it mail because in those days they would have a file and you could tack on another post to it. That’s not email. Email by definition (I am the one who defined it, I am the one who came up with the word and I am the one who created it) is a system of interlocking parts- inbox, outbox, folders and all those things.
It was in 2012, after Washington Post carried an article about your work being honoured by the Smithsonian, that the avalanche of backlash begun and peaked. Can you elaborate on that?
Everyone attacks India to be the most corrupt country in the world. But it has nothing on American corruption. Here it is deep, entrenched and done in a very sophisticated manner.
The article in Washington Post was written by a young black reporter. She started getting trolled within an hour of the piece being published. She called me up and said that my editor has thrown me under the bus and asked me to write a rebuttal against two people who were leading the backlash against me- one was a historian in the pocket of Raytheon. I chose to co-write my rebuttal with Noam Chomsky.

When they finally ran the article, they only went with David Crocker. Even then, they didn’t deny that I invented email. They said that electronic messaging existed before I came along. I am not saying I invented electronic messaging. Its existence goes back to the time of Morse code. But I did create email.
Within seven days of the Washington Post article going live, they created an internet hall of fame and gave an award to Ray Tomlinson for creating the email. This is how the system works.
Raytheon’s stock went up by $1 immediately after this announcement. There was a renewed flurry of hate campaigning against me. One blog said, “This curry stained Indian should be beaten and hanged.” If an Indian does great software coding, outsourcing or is the chairman of Microsoft, then that’s cool. But an Indian cannot be an innovator. I am labelled a fraud. Wikipedia calls me a scoundrel, a conman and a liar.
When you patented EMAIL in 1982, there was little distinction between a copyright and a patent. When it collapsed 14 years later, in 1996, why didn’t you renew it?
1980 was when the copyright act was converted to support software rights. In 1981 I was sixteen and not aware of the complexities and politics at play. I couldn’t afford a lawyer and so did all the paperwork on my own. It was only in the early 1990’s that the Supreme Court began recognizing software patents. I couldn’t file for my patent then because you can’t patent something that’s already been disclosed.
Do you grudge being denied prospective profits as a consequence of this patent issue not working out?
Walter Issacson’s new book ‘Innovators’, a book featuring solely white inventors, says that true innovation happens when the government, military and academia work together. Issacson says that the biggest motive for innovation is profit. The concept of money being the sole motive for innovation is bullshit. It is an idea promoted by those in power in order to manipulate humanity.
Today my fight is no longer about who invented email. The facts are in black and white and your readers are free to make an informed choice. I am more concerned with who controls innovation and how is humanity going to move forward.
