  1. Algorithms: Design and Analysis:  Algorithms are the heart of computer science, and the subject has countless practical applications as well as intellectual depth.  This class is for learners with a bit of programming experience who want to learn the essentials of algorithms. Stanford University offers a course in Algorithms online, which is rigorous but emphasises the big picture and conceptual understanding over low-level implementation and mathematical details. After gaining the knowledge on algorithms, one can be well-positioned to ace technical interviews and speak fluently about algorithms with other programmers and computer scientists.
  2. Python programming: With this course, one can get introduced to fundamental programming concepts including data structures, networked application program interfaces and databases, using the Python programming language. In the Capstone Project, you’ll use the technologies learned throughout the specialisation to design and create your own applications for data retrieval, processing and visualisation. This course is offered by University of Michigan online.
  3. HTML, CSS and JavaScript: This course allows you to learn the essential elements of web page development, covering HTML, CSS and JavaScript. No previous experience of these technologies is necessary, although it is helpful if you have some prior programming experience. This course covers HTML together with CSS and essential components of JavaScript, including variables, arrays, loops, events and functions. The course also explores more advanced elements of JavaScript control, including advanced use of functions, event control, array processing, and DOM manipulation. The Hong Kong University of Science and Technology offers this course online.
  4. Functional Programming Principles in Scala: Functional programming is becoming increasingly widespread in industry. This trend is driven by the adoption of Scala as the main programming language for many applications. Scala fuses functional and object-oriented programming in a practical package. It interoperates seamlessly with both Java and Javascript. Scala is the implementation language of many important frameworks, including Apache Spark, Kafka, and Akka. It provides the core infrastructure for sites such as Twitter, Tumblr and also Coursera. In this course you will discover the elements of the functional programming style and learn how to apply them usefully in your daily programming tasks. You will also develop a solid foundation for reasoning about functional programs, by touching upon proofs of invariants and the tracing of execution symbolically. École Polytechnique Fédérale de Lausanne University offers the course online.

The course is offered by CentraleSupélec.
  6. Introduction to Programming with MATLAB: This course teaches computer programming to those with little to no previous experience. It uses the programming system and language called MATLAB to do so because it is easy to learn, versatile and very useful for engineers and other professionals. MATLAB is a special-purpose language that is an excellent choice for writing moderate-size programs that solve problems involving the manipulation of numbers. The design of the language makes it possible to write a powerful program in a few lines. The problems may be relatively complex, while the MATLAB programs that solve them are relatively simple: relative, that is, to the equivalent program written in a general-purpose language, such as C++ or Java. As a result, MATLAB is being used in a wide variety of domains from the natural sciences, through all disciplines of engineering, to finance, and beyond, and it is heavily used in industry. Hence, a solid background in MATLAB is an indispensable skill in today’s job market. It is offered by Vanderbilt University.
  7. Data Structures: A good algorithm usually comes together with a set of good data structures that allow the algorithm to manipulate the data efficiently. In this course, we consider the common data structures that are used in various computational problems. You will learn how these data structures are implemented in different programming languages and will practice implementing them in our programming assignments. This will help you to understand what is going on inside a particular built-in implementation of a data structure and what to expect from it. You will also learn typical use cases for these data structures. The course is being offered by University of California, San Diego, Higher School of Economics.
  8. Object Oriented Programming in Java: This course is being offered by University of California, San Diego. This is an intermediate Java course and is recommended to learners who have previous experience in software development or a background in computer science.  In the course, one can learn learn the fundamentals of Object Oriented Programming, how to leverage the power of existing libraries, how to build graphical user interfaces, and how to use some core algorithms for searching and sorting data. And this course is project-based!

While running a digital marketing agency, Neerav Parekh regularly updated his clients on their campaign performance with reports and charts that were carefully put together.
However, the clients were quickly snowed under the blizzard of data, and inevitably demanded that account managers personally visit them and take them through these reports.

This was a laborious process and, rather than plod through it repeatedly, Parekh, a serial entrepreneur, turned to artificial intelligence (AI), the science of trying to make computers think and act like humans, for a solution.

His product, Phrazor, is aimed at automating the process of interpreting data and communicating insights. Having used Phrazor for his agency, Parekh has now sought to extend the reach of his product.
"I realised its enormous potential to change the way data was understood not just in digital marketing but in every other sphere where data was being presented," he says.

"Every company has to send performance reports to its employees or customers. The focus of our venture is to help companies communicate the insights in their data to their people at scale."

For his 14-month-old firm vPhrase, Parekh has ambitious targets he eyes companies not just in India but also in the US and targets to be in the rest of Asia and Europe in three years. "There is a huge opportunity both in India and in other countries in the analysis and interpretation of data," he adds.

Linux environment on Windows means new options for developers

Linux BASH on WIndows 10

A news of introducing new feature in Windows 10 is reviled by tech watcher from a conference on Microsoft Build 2016 conference in the United State. In this conference the special thing is that "Microsoft is bringing the Bash Shell to Windows 10." 
"The announcement received an uproarious applause from the crowd," wrote Chris Welch in The Verge.

"Bash (Bourne Again SHell) has long been a standard on OS X and many Linux distribution systems, while the default terminal for developers on Windows is Microsoft's own PowerShell."  - Frederic Lardinois in TechCrunch.

Polaris, a new code that loads website on any website 34% faster.
Faster Website Loads
Polaris developed by a TEAM MIT , this code has been programmed to gather up and evaluate all the background files of a particular website, including image files, HTML files, and JavaScript source code, way more efficiently than current systems.

Day by day websites increase its complexity and daily new module, new addons added to website. Social media and their plugins to website take down's website loading speed.
"As pages increase in complexity, they often require multiple trips that create delays that really add up," said by Ravi Netravali. "Our approach minimizes the number of round trips so that we can substantially speed up a page’s load-time."

You’re not the only but every users of internet frustrated by a site that doesn’t instantly load - pretty much everyone feels your pain, and are quite happy to drop a page like a sack of oranges if it’s going to keep them waiting. According to Amazon, every 100-millisecond delay in website loading time cuts their profits by 1 percent.

Scientists at the University of Southampton have made a major step forward in the development of digital data storage that is capable of surviving for billions of years.
Using nanostructured glass, scientists from the University's Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing.
The storage allows unprecedented properties including 360 TB/disc data capacity, thermal stability up to 1,000°C and virtually unlimited lifetime at room temperature (13.8 billion years at 190°C ) opening a new era of eternal data archiving. As a very stable and safe form of portable memory, the technology could be highly useful for organisations with big archives, such as national archives, museums and libraries, to preserve their information and records.
The technology was first experimentally demonstrated in 2013 when a 300 kb digital copy of a text file was successfully recorded in 5D.
Now, major documents from human history such as Universal Declaration of Human Rights (UDHR), Newton's Opticks, Magna Carta and Kings James Bible, have been saved as digital copies that could survive the human race. A copy of the UDHR encoded to 5D data storage was recently presented to UNESCO by the ORC at the International Year of Light (IYL) closing ceremony in Mexico.

A very easy step of creating a file starting with dot.

In windows a file is not create starting with dot. But some time we need a file that must start with dot. For example, while making a computer as a localhost i.e. Server, We need a file ".htaccess" we define the rule for apache. This file can be easily created with dot on windows in two ways.

  1. By creating a file and simply put another dot at last.
    Example:- For creating a "
    .htaccess", you have to write ".htaccess." . The last dot is drop by windows automatically.
1500-pair copper wire bundleThe telecommunications masters at Bell Labs have managed to deliver a world record connection speed of 10Gbps (10,000Mbps) over copper wires. Dubbed XG.fast, the new technology could be used to massively extend the life of existing copper wireline networks, offering telecom companies an alternative to laying costly fiber-optic networks to billions of homes that already have a telephone line — but more importantly, it might mean you finally get a serious upgrade from your ~10Mbps ADSL or ~50Mbps VDSL connection.
Bell Labs, now an R&D division of global telecoms giant Alcatel-Lucent, developed XG.fast as an extension of G.fast.
IBM has announced that it’s plowing $3 billion into two R&D programs that will hopefully make it the authority on 7-nanometer-and-beyond chip technologies.
 One R&D project will look at pushing conventional silicon chips as far as they will go (around 7nm), and the other will be tasked with finding new materials and techniques that can take us even further (quantum computing, carbon nanotubes, graphene, III-V).
 IBM also took the opportunity to remind everyone that it’s already the biggest player in 7nm-and-beyond technology, with over 500 applicable patents (more than double the nearest competitor).

UDP does not established connection between two or more server/client before sending or receiving data. In UDP connection, data never lost. Just see it:
TCP UDP Connection
Same as the TCP protocol, segmentation is done to break the data into small segment. However no sequence number are assigned to the segment. The receiving computer will not care whether the data arrive in sequence or loss. It will just join back the segments once it has received them. No knowledgement will be sent to sending computer by the receiving computer upon receiving the segments.

Therefore, UDP does not establish a connection when sending the data, there are no termination of connection.
