Google’s Project Loon : Connecting the world using Drones to provide internet for remote area

Google’s Project Loon : Connecting the world using Drones to provide internet for remote area

Google started its acquired Space Data Corp which use to work on providing internet connectivity to truckers and oil companies in united states. Project Loon started officially in Google’s secret SpaceX lab in 2011.

in 2013 Google launched 30 balloons in New Zealand in coordination with civil aviation authority.

Google's Balloon

Google’s Balloon

Google can keep balloons in the air for 75 days. One balloon, called Ibis 152, has been in air for over 100 days, while another balloon, called Ibis 162, circled the globe three times before it finally descended. The Loon team has also bolstered balloon internet speeds utilising LTE and providing 22 MB/sec to ground antennas and 5 MB/sec to handsets.

How Project Look works ?

Google’s Balloon flys 20km above the earth surface in the stratosphere, stratosphere is the second layer of the earth surface. Winds in this surface are stratified, balloon uses an intelligent algorithms which decides the direction and speed of the balloon, considering wind speed in stratosphere.

Google Loon’s Balloon Design

Loon’s balloon envelopes are made from sheets of polyethylene plastic, and they measure fifteen meters wide by twelve meters tall when fully inflated. When a balloon is ready to be taken out of service, gas is released from the envelope to bring the balloon down to Earth in a controlled descent.

Facebook’s first full scale aircraft, Aquila : Connecting Remote Areas using laser technology

Facebook’s first full scale aircraft, Aquila : Connecting Remote Areas using laser technology

Light is playing an important role in this universe, without light there is no life. People were using Light for the communication from centuries ago. Why can’t we use the same technology now to connect remote places? Facebook’s ambitious project to provide internet connectivity to the remote places on earth using laser technology and a wonderful aircraft which beam downs internet connectivity from the sky. Aquila aircraft, is a part of facebook’s Internet.org effort.

Google is also trying something great : Read More About Google’s Project Loon

Facebook’s Drones for internet connectivity

Aquila is a solar powered unmanned plane. It has the wingspan of a Boeing 737, but weighs less than a car and can stay in the air for months at a time.

Facebook’s Laser Technology Used For Connectivity

Facebook's Laser Technology 3

Facebook’s Laser Technology

A breakthrough in laser communications technology, made this possible. Facebook successfully tested a new laser that can transmit data at 10 gigabits per second. That’s ten times faster than any previous system, and it can accurately connect with a point the size of a dime from more than 10 miles away.

Facebook's Laser Technology 3

Facebook’s Laser Technology

 

This effort is important because 10% of the world’s population lives in areas without existing internet infrastructure. To affordably connect everyone, we need to build completely new technologies.

How Facebook’s Aquila Aircraft establish Connection ? 

Establishing connectivity using aircraft is a totally different idea, looks like practically impossible, proving theoretically might be easier but the real world scenario might be more challenging. using lasers might seem like science fiction. But science fiction is often just science before its time. It will be tested in the real world and continue refining.

Google announced, no forced Google Plus ( Google+) subscriptions

Google announced, no forced Google Plus ( Google+) subscriptions

Interestingly Google announced that It is stopping forced subscription for google plus, Google plus was launched four years ago in 2011. Google+ initially was very promising, number of subscriptions were more compared to Facebook. The user base growth was good enough compared to Facebook.

However the stats says a lot and the reason google deciding to say goodbye.

Google plus Vs Facebook users

Google plus vs facebook

This is interesting fact… but how many active users ?

Also Read : How Facebook using aircraft and laser beam technology to provide internet for remote places on earth

The active users of Google plus are just 35%

google plus active users

google plus active users

For example, in 2015 only 4 to 6 million users have made any public posts

Facebook has shown healthy stats : only 7% of the 2,449 registered Facebook users surveyed say that they are not active. Facebook has reached 1.44 billion active users monthly.

Read Why Facebook is on Top : Interesting Article on How Facebook Using Artificial Intelligence, Facebook identifies you based on your hair style, your dressing, your standing posture

An analyst , Anderson studies data compiled by Edward Morbius, who says that just 9% of its 2.2 billion users actively post public content.

The complete stats on all social media platforms is available here

So google is stopping their users to subscribe forcefully for google plus. so Google plus and youtube are finally splitting up. It is interesting to see google like company taking interesting moves. But It is really good move by google, they have many things to focus for the future.

8 Ways the Internet Of Things (IOT) will change the way you live

8 Ways the Internet Of Things (IOT) will change the way you live

The way technology is changing it looks like you no need to worry about anything, your every device will worry about you and will take care of you. The era of Humans control devices is over now, It changed to Devices control humans 🙂 . Before going further on this article, let us first see why Big companies creating business over IOT, so many Internet of things projects going on in market. Companies are forced to adopt new protocol since Internet of things became popular. 

First Do Read Why Google/Apple targeting Automation and Internet Of Things

It is an era of Devices Control Humans :

9 Ways the Internet Of Things will change the way you live, there are 9 key areas Everything is connected to your internet now. By the way what are these things? Things are objects you use your shoes to your dress, your office chair to your office vehicle, those tiny measuring instruments at your factory to huge machines , anything and everything.

It is just a service to connect your physical objects to digital entities and bringing intelligence in your device.

1. Smart Home and Office

Smart Home

Smart Home

A device which text you when someone rings your (wireless) doorbell; turn on the light by talking to Siri; tweet at you when your water tap is on and water is waiting in your kitchen; or, when motion is detected in your lawn, take a photo from your webcam and upload it to Dropbox.

Lock/unlock your door from anywhere just by tapping a button in your smart phone, this is not a great thing but where Internet of things will come into picture? Assume that you will be coming to your home daily at 6PM? almost 25 days you will come around 6PM in a month? but some times you may come home early due to you 1st shift in work? all these data will be stored in server and analysed. You device will become clever, intelligent by analysing the data. By chance if some one hack your device and opens the door, you device can predict some one unlocked at an odd time, and will notify you immediately. ” Hey ! it looks like you came home early ? if not respond me quickly it is not your usual time of coming home early, your not into 1st shift also. Looks like I am hacked 🙂 please respond…”

Internet of Things now built in your kitchen, connected objects to smarten up your home, Smart home security,

Temperature control at your home ?

Nest Thermostat

Nest Thermostat

Your kids are at door steps, you are still at your office. Ofcourse you can see your kids standing infront of your home using your Internet Of Things connected smart lock. You unlock your door and set room temperature which is suitable to your kids.

Over several days, your thermostat system learn that your kids prefer what temperature and your grand ma prefer which temperature. next time when your kids come home thermostat will automatically sense it ( your do software update over internet) and will adjust the temperature.

Lights controlled at your office, you no need to use ID tags now at office, work space door will open as you go near.

Facts says that smart-home market could grow to $60 billion by 2020.

Artificial Intelligence helps to achieve all these smart devices : See how Artificial intelligence helps Facebook

Read Apple Home Kit, google Brillo and the future of Technology

2. Transportation

Your vehicles now are automated, you come near to your vehicle in parking slot, it automatically take reverse and will come just infront of you.

They analyse the traffic data collected over the period of time, will change the route by considering google maps data, history and will decide which route to take today. An urban planner should change and adopt technology and an urban planner should look smart for this internet age.

Your trains will suggest you to change the schedule by analysing peak times, by analysing people’s preferred timings or by analysing traffic data from maps

3. Smart Cities

Your traffic signals will change the timings by analysing traffic data collected or waiting time of people at signals. In Banglore traffic there are so many signals where people simply wait long even though no much traffic, no more such mistakes.

You are near to a shopping mall ? and there is an offer on your favourite branded shirt ? Internet Of Things will make you aware of that, you will never miss that offer 🙂

The street lights will turn on only when people/vehicle approaches near, smart LED lights can be used for this.

Smart LED streetlights in San Diego turn on only when a pedestrian or vehicle approaches—the city recently replaced 3,000 old streetlamps with sensor-equipped ones to save an estimated $250,000 a year.

Your garbage cans are now solar powered and will crush the garbage, will dispatch it to public garbage collector system, they will become smarter they analyse what kind of materials you use, which is good for what by analysing data collected through IOT and will separate out items and learn to segregate by itself 🙂

Real time example ? Philly (Philly is an informal name for Philadelphia, a major city in Pennsylvania) has been able to reduce the number of weekly garbage-collecting shifts from 17 to just three, and realize $1 million a year in savings on fuel, maintenance and labour costs.

London now testing smart cities operating system, An operating system designed to power the smart cities of the future will be put through its paces in London. By 2050 it is estimated that 70% of the world’s population will live in cities. Living Plan IT estimates that £13tn will be spent in developing and regenerating urban spaces between now and 2020.

4. Smart Manufacturing

You devices, sensors, measuring instruments at manufacturing hub now analyse big data collected every day. They will do slight modifications in their process, will grab you more revenue by optimising themselves.

Your smart system will analyse everything and will suggest you for a smart movements of devices, machines which reduces amount of work and increases the manufacturing speed.

Harley-Davidson motorcycle plant in York did something great, One analyst recently told The Wall Street Journal that installing a manufacturing execution system into a single factory can cost between $500,000 and $1 million. But according to SAP (which provided the Harley plant’s software), the factory can now turn out 25% more bikes with 30% fewer workers. Instead of delivering one of its 1,700 bike variations in 21 days, it can manage delivery in a mere six hours. Reference

5. Smart Energy Systems

Collection of data over several years helps to innovate new energy plants, scientists were able to invent wind turbines without blade, bird lovers would be happy with these blade less wind turbines

6. Smart Health Kit

Now a wrist band in your hand analyses you pulse, your breath and predicts well before you will suffer from a disease, there are devices which will analyse your breath and predict breast cancer, Apple has invented Apple watch which is integrated with bunch of sensors.

A device can analyse your heart beat data collected several months and can suggest you precautionary activities to keep you away from heart attack.

Apple-HealthKit-dashboard

Apple-HealthKit-dashboard

7. Smart Agriculture

Now sensors fitted in your field can constantly analyse weather variations and suggest you to take necessary steps for better farming,

They can analyse and predict the time elephants, birds come and spoil your farm and alarm you well before they arrive or can switch on low strength electric fence at the time only.

Sensors can analyse soil moisture records and will switch on the pump only when it is required, can even add fertilisers in water the amount which is required

8. Smart Entertainment devices

Your MP3 players can now analyse which songs you listen what time, they can even analyse the place you are currently in and switch to the song you prefer to listen that moment. 

Your music system is now smarter then ever, it can play ABC song when your kids arrive at home from school.

Era of Artificial Intelligence : Facebook new algorithm to identify people

Era of Artificial Intelligence : Facebook new algorithm to identify people

Amost five years ago face recognition was a trend your mobile applications use to set ur face as password for your smartphones, Windows OS introduced face recognition to unlock the system, Facebook used face recognition for tagging people in the group photos. 

But Face recognition is now very old, technology is changing so fast that today’s technology will become out dated tomorrow. Every day something new coming to market, people are becoming more innovative than ever. Recognition ? what else can one do other than face and voice recognition ?

Identity of a person based on his unique characteristics

Every person will be having his own uniqueness in his characteristics, the way he dress, his hair style, his body shape, his standing posture what else ?. Identifying a person based on his characteristics can be achieved by properly analysing the data.

Facebook can recognise you in photos for tagging, even if you’re not looking

Facebook is experimenting on a new algorithm which can recognise a person based on his unique characteristics even though his face is not visible. Yann LeCun, head of artificial intelligence at Facebook, is leading a team of researchers. The team is analysing more than 40000 thousands photos from flickr and experimenting in the lab.

However there are certain privacy concerns raised by experts, but Facebook will surely find a way to keep things secured.

Facebook Shows how artificial intelligence improve Facebook to show you perfect posts

Facebook has set up three AI labs so far, the company is investing enough time and effort on AI which helps Facebook to server the content that matches the people’s interest. Facebook revealed backend recognition tech in F8 conference. CTO Mike Schroepfer described new systems for identifying the content and context of videos and sentences.

Facebook working on secretly working on Language Technology Group and experimenting on recorded voices and converting it into text. It has been planned by Facebook to release the feature in Facebook messenger where it converts voice to text.

Facebook’s Video AI prototype

Facebook has developed video AI prototype that identify 485 types of sports but recognises tiny differences among games. See the video given below

AI can read sentences and determine things like who possesses what, or where is an object.

Check this experiment 🙂 AI recognises content from the Lord Of The Rings and able to answer question about the story.

Why AI Matters for Facebook ?

The one and only aim to understand the content, show the relevant content to the user. This is really very much required for Facebook like company because if some one else enter into the market with a new idea then people might start looking towards it. The only thing every one must focus on is never allow your user to think about something else.

Facebook, Google and Apple are really doing a great job in this aspect, Nokia once was a leading mobile phone manufacturers, but one product like iPhone killed Nokia. If you are an entrepreneur then you must learn a lesson out of it.

Think about it.

Selecting certain fields in Hibernate Criteria using Projections

Selecting certain fields in Hibernate Criteria using Projections

This is not a great post but many people will face this issue and the solution is very simple for which many will spend hours of time to find it.

Issue faced by many are selecting certain fields of the table using hibernate criteria, converting array of Objects (Object[]) to respective custom class object, Even after converting the values for the fields will be set to default rather than actual values of the fields.

Take an example :

  Class Person {
    private Integer personid;
    private String personname;
    private String mobilenumber;
    private String permanentaddress;
    private String localaddress;

    public Integer getPersonid(){ }

    public void setPersonid(Integer personid){ }

    public String getPersonname(){ }

    public void setPersonname(String personname){ }

    //Other fields getter/Setter
    
  }

In this example assume that you wish to fetch only personid and personname using hibernate criteria

Fetching only selected fields using Hibernate Criteria







  List persons = null;
  Criteria criteria = sessionObject.createCriteria(Person.class);
		 criteria.setProjection(Projections.projectionList().add(Projections.property("personid")).add(Projections.property("personname")));

 criteria.setResultTransformer(Transformers.aliasToBean(Person.class));
 persons = criteria.list();

Issue : All fields are getting empty/default values after using hibernate projections

This issue is a very difficult to tackle, because hibernate doesn’t through any exception for this but it returns objects filled with default values of fields.

Solution: The solutions is really simple, just use an alias to each field in projections

//See alias personid and personname for both the fields
//Projections.property(“personid”),”personid”) and Projections.property(“personname”),”personname”)

 criteria.setProjection(Projections.projectionList().add(Projections.property("personid"),"personid").add( Projections.property("personname"),"personname"));

 

The above solution doesn’t work for One-To-Many relationship also when there is an aggregation, has-a relationship.

A Wrapper to fetch selected fields using hibernate Projections for One-To-Many relationship

Download the library given below and import it in your project, then define a Response Class like PersonResponse.java, which should be exact replica of Person.java , where it holds all details of a person fetched from database person table.

then just use the below code 

personCriteria.setResultTransformer(new AliasToBeanNestedResultTransformer(PersonResponse.class));

Regular Expressions : How Exactly they work internally ?

Regular Expressions : How Exactly they work internally ?

Regular expressions were playing major role in computers from several decades, they are not as simple as we think. They are need extensive computational power, a decade before regular expressions were a big headache for computer programmers and scientists because they were consuming lot of time to complete the task.

History behind Regular Expressions :

A neuroscientist  who tried to understand how the human brain could produce complex patterns using simple cells that are bound together. In 1943, Warren McCulloch and Walter Pitts published “A logical calculus of the ideas immanent in nervous activity”.  this paper had a great influence on computer science during that time. In 1956, mathematician Stephen Kleene developed this model one step further. In the paper “Representation of events in nerve nets and finite automata” he presents a simple algebra. The terms Regular Sets and Regular Expressions were born from then. As mentioned above, Kleene’s algebra had only two operations and one function. In 1968, the Unix pioneer Ken Thompson published the article “Regular Expression Search Algorithm” in Communications.

A Pattern in regular expression :

How to learn regular expressions ? How to understand regular expressions?. They look confusing to understand regular expression but regular expressions are an elegant way to do some string manipulations.

We have studied finite automata and the regular expressions all just works on this theory, but Most modern programming languages (Perl, Python, Ruby, Java (and JVM based languages), C#) do not use this approach rather they use recursive backtracking approach. But finite automata is really good to understand regular expressions with its state diagrams and not a bad idea to implement in this approach may be recursive backtracking is better. So do you need a help to understand regular expression? here it is…

Let us take one example, Validating an email address

If this is your regular expression

[a-z][a-z|0-9|]*([_][a-z|0-9]+)*([.][a-z|0-9]+([_][a-z|0-9]+)*)

The respective state diagram might look like below
