Software license is a legally binding agreement that specify the terms of use for an application and it defines the rights of the of the software producer and of the end user as well. A software license is a legal instrument (usually by way of contract law , with or without printed material) governing the use or redistribution of software.     Source: https://en.wikipedia.org/wiki/Software_license With the software license in contrast to proprietary software licenses, ownership of the particular copy of the software will go to the end user. It’ll not remaining with the publisher of the software. Then by default end user afforded all rights granted by copyright law to the copy owner. :) Please note the Copy owner is not the same as copyright owner . When ownership in a software copy is transferred ownership of the copyright still remains with the publisher. There are several types of the software licenses. They are Proprietary license GNU Gen...

It’s been few weeks since my last article. So today I'll be talking about IPv6. The next generation of the internet protocol is IPv6. What is IPv6? Internet Protocol version 6 was developed by the Internet Engineering Task Force(IETF), which was starting in 1993 in response to a series of perceived problems, primarily with the exhaustion of the current, IP version 4(IPv4) address space. Simply IPv6 is the replacement internet protocol for Ipv4. With the 32 bit address format, IPv4 can handle a maximum of 4.3 billion unique IP addresses. With its 128-bit address format, IPv6 can support 3.4 x 10 38 unique IP addresses. There are different types of IPv6 addresses: Unicast, Anycast and Multicast. Unicast addresses are the well known addresses. A packet sent to a unicast address arrives exactly at the interface belonging to the address. Anycast addresses are syntactically indistinguishable from unicast addresses but they address a group of interfaces. The packet de...

What’s C, A and P? Consistency is the easiest one. It roughly means that the clients get the same view of data. By saying that a system is consistent we often mean strong consistency, but it also can come in different flavors. Availability is a property saying that every request to a non-failing node will return a (meaningful) response. The response may not contain all data (so the harvest will not be 100%), but it should be useful for the client. Partition tolerance means that the system will continue working even if any number of messages sent between nodes is lost. This can be e.g. a network failure between two data centers, where nodes in each data center form a partition. Also note that a failure of any number of nodes forms a partition (it is not possible to distinguish between a network failure and a node failing and stopping to respond to messages). The basic statement of the CAP theorem is that, given the three properties of Consistency, Availability, and Pa...

What is DevOps? It's a movement of people who think it's time for change in the IT industry - time to stop wasting money, time to start delivering great software, and building systems that scale and last. This movement is being called Devops. It’s born of the need to improve the IT service delivery agility, and this emphasizes the communication, collaboration and integration between software developers and IT operations. Rather than seeing these two groups as silos who pass things along but don’t really work together, DevOps recognizes the interdependence of the software development and IT operations and helps an organization produce software and IT services more rapidly with frequent iteration. How does it help you? The Devops movement is built around a group of people who believe that the application of a combination of appropriate technology and attitude can revolutionize the world of software development and delivery. DevOps lifecycle The DevOps l...

What is Internet of Things? The internet of things(as it’s also known, IoT) is an idea that tech companies and pundits have been discussing for decades, and first internet connected toaster was unveiled at a conference in 1989. When we consider IoT it’s about connecting devices over the internet, applications, letting them talk to us, and each other. The IoT is significant because an object that can represent itself digitally becomes something greater than the object by itself. No longer does the object relate just to you, but is now connected to surrounding objects and database data. When many objects act in unison, they are known as having "ambient intelligence." Why is the Internet of Things important? You might be surprised to learn how many things are connected to the Internet, and how much economic benefit we can derive from analyzing the resulting data streams. Here are some examples of the impact the IoT has on industries: Intelligent transport s...
