Every node(system) has the ability to update the record and the most popular record becomes the de-facto official record to becom...

Just imagine how exciting and amazing this w orld would be if everything around us is connected, it would not only save our time but also reduce our unnecessary tensions and stress. And since human-kind has evolved and developed many-folds, thus, we have a super-power technology to turn this into reality and that’s termed as “ IoT ” or “ Internet of Things ” - the connection of Physical World with the Cyber World . Sounds fascinating, isn’t it? Now, let us see how it works in reality . The Cyber-Physical system is configured or designed by following these functions: ·         Connection level : It involves attachment-free or wireless communication, monitoring and recording the physical conditions of the environment using sensors and organizing them at a central location. ·         Conversion level (Data-to-information): Involves data-correlation, tracking of machine-failures, malfunctions, reduces dow...

Have you ever imagined how do they build such beautiful web-pages and so much user friendly websites, or you yourself have dreamt of developing one of your own? Then you must be aware of UX/UI designing and learning about its applications would give you a complete idea of what you want to build and how would it look like in the real world. source: Google Images UX Design refers to the term  User Experience Design , while UI Design stands for  User Interface Design . Both elements are crucial to a product and work closely together. But despite their professional relationship, the roles themselves are quite different, referring to very different parts of the process  and the design discipline. Both of them have a plain goal of making the user interaction simpler and efficient . The User Experience Design or UX Design is more or less non-technical, as it involves content-development, prototyping, analysis and iteration, basically the interaction with the users ...

Big data analytics is the process of examining large and varied data sets -- i.e., big data(Black box Data, Social media Data, Stock Exchange Data, Search Engine Data, Transport Data, Power grid Data) -- to uncover hidden patterns, unknown correlations, market trends, customer preferences and other useful information that can help organizations make more-informed business decisions. Volume, Variety and Velocity are the three V’s of Big Data. A person involved in this kind-a-job is called to be a “Data Analyst”. And to receive this tag by large group of people he/she needs to be super good at statistics and if accompanied by software developing skills he/she would be called as “Data Scientist”. How to be a renowned and efficient data scientist? Technical Skills that the person needs to be good at are: Statistical methods and packages (e.g. SPSS) R and/or SAS languages Data warehousing and business intelligence platforms SQL databases and database querying languag...

Now you are stuck in a problem and your only judgement to it is "either live with it or hang yourself up and the most better one is to kill or segregate all the disturbing creatures!".Dude, please wake up, look at the world and see,it isn't that small as you are perceiving it. Sometimes, there are few situations in our life(especially problematic ones) when our brain stops working, everything around us seems frustrating, every single tiny bit of action of others, seems as a threat. You start feeling that the mere presence of others around you is to only worsen your condition. Some brave beings try to handle it, and some innocent ones fall in the trap of the situation and get entangled into it.To those, who think that they can't handle it, instead they should know that they don't need to handle it.All what is required is to have a look at the prism keeping it at a different angle. The simplest solution to this problem which I can think of, is to perceive th...

Have heard the term "Web Penetration" before and want to know what it is and how is it related to you? Then here you go... Web penetration is an authorised(legal) simulated(more or less like real) attack on a system to check its vulnerability for cyber attacks. It is a component of Security Audit. It comprises of two parts: "Discover the vulnerabilities"(legal) and "Exploit the vulnerabilities"(Illegal). It determines whether unauthorised access or other malicious activity is actually possible or not. Sounds interesting isn't it? Vulnerability Assessment is an essential part of Web penetration. There exist many testing techniques e.g. Fuzzing(cool name huh!! well its a part of vulnerability assessment) is a software testing technique in which random or invalid data are provided which can create invalid behaviour in the program and can check the program for failure in built in code assertions and potential memory leaks. And as all the import...
