Motivation We’re in a community that petabytes of transactional data are stored at large clusters, usually partnered with Hadoop. To analyze such data, it’s popular to use interactive data mining tools (e.g. R, Zepplin) over the Hadoop data-space. Going with the technology buzz in big data over last decade, MapReduce acts as a reliable cluster computing frameworks for large scale data ...

Hi Folks, Today, I’m going to brief you an important calculus (i.e. algebra) at theoretical computer science, The theory of process calculus has been used for modeling concurrent system formally. This article targets to provide reasoning about the behavior of cryptographic protocols. π-calculus π-calculus can be thought as similar to Communicating Sequential Processes (CSP), in the way it uses named channels on restricted ...

Apache Storm requires a topology configuration which is deployed to run under many instances of JVM. In a single instance, the subset of topology is drove by threads spawned by worker’s JVM. It is further parallelized by task threads that runs serially on an executor parent thread. A running topology consists of many such JVM processes running on many machines ...

Hi Folks, In today’s middleware, we must allow for fluid placement of computation and data between everything from sensors to multi-domain clouds. In such environments, the problem of maintaining consistency is exacerbated by widespread replication — including client-managed data. Replication play as the key factor to manage large scale fault tolerance systems. The amount of time which a service is ...

Pull-out your myths, in-memory computing is just right here! GridGain - In-Memory Computing As any fast growing technology In-Memory Computing has attracted a lot of interest and writing in the last couple of years. It’s bound to happen that some of the information gets stale pretty quickly – while other is simply not very accurate to being with. And thus ...

Hi Folks, Today I’m going to re-cap a most interesting mathematical property to model natural interaction between two or more living beings – The zipf property. It was introduced in the early 20th century where it kept un-noticed until it was used by famous mathematicians. The property was named after George Zipf (1949) who first popularized the empirical finding. We have complex messy models, yet ...

Hi Folks, There’d been nearly dramatic shift in computer industry not to build a bigger or faster processor but putting more cores in a single processor chip, by making it smaller in order to get better throughput. If we want to run our applications faster, we need to learn parallel programming which get use the cores concurrently. That increasingly influences ordinary ...

TechCrunch One of the common bits of advice you’ll see people giving you around this celebrity picture hack is to enable two-factor authentication on your accounts — including Apple’s. That’s good advice, but it wouldn’t have protected any of these celebrities and it doesn’t protect the other accounts that are compromised by hackers that are able to obtain an ...

Hi Folks, Recently I made my way on reading some security aspects related to wearable computing. Many commercial vendors introduced Two-step authentication to claim the correct identity of their users. But that have been in the edge recently mainly because the emergent of wearable computing. As an example Google have two-step authentication for all their services by sending users a randomly ...

HI Folks, By injecting forged messages to the remote server, attacker can truncate TLS connections over malicious networks. Exploiting most logical web applications vulnerabilities, Truncation attacks were mostly executed on casting votes in Helios elections, also taking full control over Microsoft live accounts & temporarily accessing to Google accounts. Attacker doesn’t rely on installing malware on client computers. But as long as he can ...

HI Folks, Today’s post is going to be more about Artificial Neural network, I will describe some approaches we used in building a perceptron based classification system that guesses the emotional state of faces presented as input where the recognition of facial expression and hence emotion and mood of a person is presented. The system for classifying the expressions of supplied face into ...

HI Folks, Today it’s going to be more interesting where we traverse the scene graph & render it to scene, We’ll talk about algorithms & design patterns we used in the implementation briefly. As the way scene graph structure & the way we want to render objects, we need to visit node’s children before we continue to its brother. We ...

HI Folks, Today Let’s talk more about the node structure in the scene graph. Always you can review & extend what I say Scene graph follow some common properties in defining node structure, bounding volume is one of them, it defines a simple volume like axis-aligned box or sphere where it encloses the contents of all nodes below the current ...

Microsoft Robotics Developer Studio (aka MRDS) is a toolkit and a platform, where many libraries are given to design and control robots. Here is a simple implementation of a controller program that can guide a robot in a simulated environment, such that it follows a pre-specified path. The path is given as a sequence of coordinates, and the program use the ...

HI Folks, Here am giving you a step of start to learn how to implement a node based scene graph for real time rendering,  In the Final part of this series you can review the code that I implemented for basic scene graph rendering, This is the solution to the course work assignment : Advanced Graphic & Application in Umea University, ...

HI Folks, HPC2N (High Performance Computing Center North ) is a national center for Scientific and Parallel Computing. HPC2N Web . You can get an idea on what they’re doing by visiting their web page Bo in Abisko Inaugural Yesterday We’ve met 5 important resource persons in their research group including Bo Kågström who is the group leader & the one who invited us to ...

Motivation There’ve been nearly dramatic shift in computer industry not to build a bigger, faster processor but putting more cores in a single processor chip, making it smaller in order to get better throughput. So the running applications get use the cores concurrently & that increasingly become ordinary programmers to concurrent programmers. But here’s the problem: concurrent programming is bit ...

HI Guys, I spent no-works today’s evening. So gave out a shot to what I love most : MUSIC. SoundForce..Yes..That’s It! It’s just the beginning, hope to implement it Further. Implemented it using SoundCloud API. You can query anything & strip your music He He..See you soon! SoundForce

Set-up your SINGLE node Hadoop cluster HI Folks, It’s long time that I started to try Hadoop. But you know after heavy setup days today I succeed following above great post by Mr. Michael G. Noll which is a step-by-step post for Hadoop beginners to dirt their hands in distributed File system. You can try his suggested word count examples. Also he has some ...

Hello Folks, Let’s add some documentation comments to the project & submit patches You can see that I add simple comments above public constructor describing what it’s up to do. I wrote them just to the DEMO purpose. Add Comments The procedure is to write your patch to a text File & attach in your opened issue. You can’t commit ...
