Here's What No One Tells You About Career In Hadoop

Information technology has strengthened its roots in almost every sector of life. Be it health, business or even entertainment, we have seen revolutionary changes that became possible only because of the innovative participation of information technology. Information technology is never outdated or obsolete, and this is because it’s a continuously changing industry. So, there was a time when the website was nothing but the combination of HTML code and CSS, unlike today where AngularJS, PHP, ASP and tons of other options are involved in creating a website to fulfil the need of business in the most convenient ways possible. Today, we are dealing with big data (from big, I mean very large set of data), but in order to process that data in a distributed computer environment, you need to have expertise in Hadoop. In this infographic, we explain what Hadoop is , the scope of Hadoop and why it’s important for you to get yourself upskilled to be a creative Hadoop developer.                  Now you know why Hadoop is important and how you can be the kind of Hadoop developer companies are looking for.

Ways to Host MongoDB On Google Cloud Platform

When we talk about databases, the fastest growing database technology MongoDB comes into the picture.  The world is on the verge of information overload and huge databases are needed to store and manipulate this information. Google Cloud Platform is the cloud computing platform offered by Google which supports the same infrastructure that Google uses for its end user products like Google Search and Youtube. Google allows the deployment of MongoDB on its cloud platform and it has given strength to the organizations and industries dealing with huge databases. Zeolearn offers Mongodb course under the supervision of professional trainers. You can easily deploy the Mongodb to the Cloud platform. You need to consider the following factors before deploying Mongodb to Google Cloud Platform Prerequisites for Deploying MongoDB to Google Cloud Platform Selecting Machine Type Google Compute Engine delivers virtual machines running in Google's innovative data centers and worldwide fiber network. Standard machine type for MongoDB deployment should have good balance of CPU and memory resources. High-memory machine types generally considered as ideal for workloads that require more memory relative to CPUs. Performance in MongoDB servers can be increased by minimizing the disk access. Disk access can be minimized by resizing the MongoDB server instance such that the active working data set can be kept in memory. Deploying MongoDB arbiter servers includes the usage of g1-small. Arbiter are mostly idle and only exchanges heartbeat information with other MongoDB servers. It becomes active for only short period of time when it’s the time to select new primary need .Shared core instances of g1- small is certainly an inexpensive way to reserve critical CPU cycles which are needed infrequently. Configuration of persistent disks High-performing and consistent block storage, two most important things offered by Persistent disks. Persistent disks functionality is similar to the physical disks in a desktop or in a server. These are durable storage devices which are located independently from user’s virtual machine instance, so user can detach or move these disks for keeping the data even after deleting the instances. Compute Engine persistent disks are available as standard hard disk drives (HDD) or solid-state drives (SDD). Sequential read/write workloads are supported by standard persistent disks but it is not useful for random read/write workloads. SSD persistent disks are considered best for MongoDB deployment because they provide the best ratio of price to performance and supports high rates of random input/output operations per second(IOPS). Things Need to take care While Sizing The Disks These things one should keep in mind while sizing the disks for MongoDB data The size should be pre computed and calculated which is needed for users data. The disk size calculated should be checked for performance, whether this size is suitable for the user to write his/her data, journal files and logs. If this is not effective then user should go for larger size. Ways To Deploy Mongodb On Cloud There are number of ways to deploy MongoDB on Cloud Stage, including (but not limited to):Cloud launcher for MongoDB It is considered as the simplest way of deploying MongoDB on Google cloud platform, allowing quick upload of replica set through the web.MongoDB cloud Manager Supporting more complex deployments than the Cloud Launcher , such as complex replica sets or sharded clusters. However, user can configure the Compute Engine instances and deploy software agents manually. Google Cloud Deployment Manager Setting up of MongoDB Cloud Manager automatically includes the resource provisioning and configuration steps .If it is not done automatically anyways users has to do all this manually. Cloud Launcher for MongoDB We can deploy functional software packages that can run on Cloud Platforms very easily and quickly with the help of Google Cloud launcher. It lets the user to deploy the software with the predefined configurations without any manual changes in the software, virtual machine, storage or network settings. Cloud launcher for MongoDB provides a quick deploy of replica with seven virtual machines and simplifying the initial configuration steps. By default, MongoDB replica set is deployed by Cloud Launcher with primary, secondary and arbiter. According to the desired configuration it lets user to choose its preferred machine type and disk type. As the replica set gets uploaded, user can update its cluster information. MongoDB Cloud Manager MongoDB Cloud Manager is the easiest way of running MongoDB on Cloud. MongoDB Cloud Manager constitutes of MongoDB’s configuration, query optimization, monitoring and backup facilities. It provides a backup plan solution for different MongoDB deployments .MongoDB Cloud Manager allows the deployment and configuration of MongoDB replica sets and shared  clusters. It also includes the ability of monitoring ,that allows you to view over one hundred MongoDB metrics, complete with custom alerting and integration with other application performance monitoring solutions. Using MongoDB Cloud Manager with Google Cloud Platform: Creating a MongoDB Cloud Manager account and copy the "mmsGroupId" and "mmsApiKey". Get equipped with Compute Engine instances and persistent disks for your MongoDB cluster. Configuring persistent disks to each Compute Engine instance. MongoDB Cloud Manager Automation agent should be installed and configured. Return to the MongoDB Cloud Manager interface and complete the cluster setup.   MongoDB Cloud Manager using Deployment Manager Cloud Development Manager templates can be used alternatively to perform all of the steps in Setting up MongoDB Cloud Manager. These templates are used to automate the configuration of Compute Engine instances. Deployment Manager allows you to specify all of the resources needed for your MongoDB deployment in a declarative format. In addition, you can parameterize your templates , which allows them to take different input values and makes them more flexible and reusable. Deployment Manager templates are organized into declarative configurations comprised of resource definitions and runtime properties. Deployment Manager allows the user to know about all the resources needed for his/her MongoDB deployment in a declarative format. The templates are parameterized in Deployment manager, which allows them to take different input values and making it more flexible and reusable. Declarative configuration of the templates comprises of resource definitions and runtime properties. Templates provided by MongoDB Cloud Manager allow users to quickly get equipped and configure multiple Compute Engine instances. Each of the instances are associated with persistent SSD for data storage, and automatically configuring the MongoDB Cloud Manager Automation Agent. Following steps are required to use Deployment Manager templates to bootstrap MongoDB Cloud Manager: Creating a MongoDB Cloud Manager account and copying the "mmsGroupId" and "mmsApiKey". Clone the mongodb-cloud-manager GitHub repo. Configuration should be deployed using the values copied earlier, well explained in mongodb-cloud-manager README file. Return to the MongoDB Cloud Manager interface and complete the cluster setup.

Release of R 3.3.1

R-3.3.1.tar.gz (codename "Bug in Your Hair") has been rolled out in the market recently and bugs has been fixed in this version which was there in the earlier releases. Binary version of the release can be downloaded from here and tar.gz  source code is now also available for downloading. List of bugs fixed in the release is mentioned here but it has not introduced any new features which could be helpful for the developers. Update to R 3.3.1 is now available for Windows Windows users can now easily upgrade it to the latest version of R using the installer package provided by R. Running the following codes in R gui will do the trick. install.packages("installr") # install setInternet2(TRUE) # only for R versions older than 3.3.0 installr::updateR() # updating R. “updater()” command detects whether any new version of R is available or not, if it’s available then it automatically download and install it .If still CRAN shows older version for update then preferably opt for changing your mirror or else try after some time, it takes at least 24 hours to get an updated version on CRAN. Changes in R 3.3.1 Following are the list of all the bugs fixed in this version. R CMD INSTALL and hence install.packages() gave an internal error installing a package called description from a tarball on a case-insensitive file system. match(x, t) (and hence x %in% t) failed when x was of length one, and either character and x and t only differed in their Encoding or when x and t where complex with NAs or NaNs. unloadNamespace(ns) also works again when ns is a ‘namespace’, as from getNamespace(). rgamma(1,Inf) or rgamma(1, 0,0) no longer give NaN but the correct limit. length(baseenv()) is correct now. pretty(d, ..) for date-time d rarely failed when "halfmonth" time steps were tried and on ‘inaccurate’ platforms such as 32-bit windows or a configuration with --disable-long-double; see comment #15 of. In text.default(x, y, labels), the rarely(?) used default for labels is now correct also for the case of a 2-column matrix x and missing y. as.factor(c(a = 1L)) preserves names() again as in R < 3.1.0. strtrim(""[0], 0[0]) now works. Use of Ctrl-C to terminate a reverse incremental search started by Ctrl-R in the readline-based Unix terminal interface is now supported forreadline >= 6.3 (Ctrl-G always worked). diff() now keeps the "units" attribute, as subtraction already did, The updated list of bugs fixed has been taken from the Official R blog.

7 Ways To Increase Your Post’s Visibility In Social Media

Social Media is a phrase we use in common in our day to day life. Earlier it was like “If you aren’t on Google, you don’t exist”, but it has changed completely now. Websites like Facebook, LinkedIn, Twitter and Google+ have millions of users and still counting. Social media is a popular way to use direct marketing. This type of marketing allows one-on-one connection and gives a chance to show who you are to the rest of world. With an opportunity like this, you want to capitalize on the connection. Engagement allows you to do that. In this continuously changing world of unique blogging practices, it has become immensely important to adopt the best way to create an interesting and engaging post. Let’s try to understand some aspects of Successful and Engaging posts to increase social media visibility:- 1: Posting should be purposeful The post should be meaningful.  Posts without any meaning don’t catch viewer’s eyes The content has to be written in grammatically correct and should have some points useful for the viewer. Content should connect with the targeted audience. 2: Share-Worthy Posts We might have seen and read a few posts which don’t talk much about its respective headline. These posts are not worth sharing because they don’t contain any relevant content for any particular person. Deviating from the topic doesn’t help the blogger to get any attention. 3: SEO Friendly Content Content should be interesting to the users as well as SEO optimized. Don't annoy your users with irrelevant content. Catchy Headlines The headline is the first thing that reader notices and it has to be catchy, otherwise, he/she will never get the interest in reading the post. The title of your post/blog should let readers know right away what your blog is about. Experiment  with different catchy headlines Optimizing With Keywords Use keywords in your context text Link your keywords with relevant to your content Don’t stuff your content with more keywords 4: Add Interesting Images Images not only a great look to the post but it also allows the reader to relate himself to the words written. Images should be used more often in the post. It increases the readability and reader don’t feel bored while reading the post. 5: Proper Linking Links are always helpful for posts because it shows the relevancy of the posts and from where your post has sourced. Interesting links attract more users to come and visit the post and this gives them a way to see a relevant video or read relevant article. 6: Promote Your Content Sometimes it becomes difficult to promote your brand single-handedly Having same demographic or overlapping fans could help a lot in this strategy. For example, A tourism page featuring a restaurant within its area that will make sense for any restaurant or else it will be treated as annoying spam. 7: Cover Trending Topics The post should always talk about the topics which are trending. This increases the visibility of the post because many of them will be interested in viewing topics which are new in the market. If the particular blog deals about something older then it will have less importance. So, it is necessary for the bloggers to talk about the topics which are new and liked by many people. These can be only a few ways to remodel and reconstruct your blog. What are you waiting for, put on the thinking cap and start writing something useful and attractive? Who doesn’t want to get noticed and followed by millions of people?

Big Data? Hadoop might be your thing

Software as a service(SaaS) can turn out to be the Sales and Marketing’s biggest demon if the business plan is a faulty one. The Software as a service(SaaS) model itself has little to take blame for: after all, the initial plan was to be shared with entities that could construct the ideal enterprise level solution and provide its constant support during the implementation. Hadoop like many of the other big data solutions has been a game changer but unlike other big data solutions, Hadoop is more accessible.  Amongst others, its benefits include,though: Computing Power: Its distributed computing model quickly processes big data. The more computing nodes you use, the more processing power you have. Flexibility: Unlike traditional relational databases, you don’t have to preprocess data before storing it. You can store as much data as you want and decide how to use it later. That includes unstructured data like text, images, and videos. Fault tolerance: Data and application processing are protected against hardware failure. If a node goes down, jobs are automatically redirected to other nodes to make sure the distributed computing does not fail. And it automatically stores multiple copies of all data. Low cost: The open-source framework is free and uses commodity hardware to store large quantities of data. Scalability: You can easily grow your system simply by adding more nodes. The Little administration is required. -          SAS Most of us have complained about Java’s enterprise level having a low storage tolerance. Coding repositories do try to address that, but there’s just not enough power in that. For those of you looking for Hadoop’s standalone can now do so in some relatively easier steps. Virtual Box You will need to get started with the Unix flavour of choice. I am not for ditching the base OS, especially if you are using windows. Even if you are not using Windows, I still recommend a virtual machine with a Unix flavour. Optimally Ubuntu is a very good choice, but Red Hat also works well. You can follow the step by step for the installation over here. Just ensure that you keep your ram proper on the VM as Hadoop is not a light software to configure. Map Reduce Think of Map reduction like splitting your data into equal chunks for better storage. There are two sets of operations to it: the map tasks and the reduce tasks. Once the reduction is complete, the storage takes place in a different format of the file system. Optimal and simple. The framework possesses the same computer and storage nodes, though, which can be attributed as one of its criticisms. The framework is also divided between the master Job Tracker and the slave Task tracker per cluster node. Since your data is stored on these clusters, the Tracker schedules and then executes. Take a look at the source code for an example as Apache is pretty much in line with Hadoop.     Public class WordCount { public static class Map extends MapReduceBase implements private final static IntWritable one = new IntWritable(1); private Text word = new Text(); public void map(LongWritable key, Text value, OutputCollector String line = value.toString(); StringTokenizer tokenizer = new StringTokenizer(line); while (tokenizer.hasMoreTokens()) { word.set(tokenizer.nextToken()); output.collect(word, one);      }   } } public static class Reduce extends MapReduceBase implements Reducer public void reduce(Text key, Iterator values, OutputCollector int sum = 0; while (values.hasNext()) { Mapper { output, Reporter reporter) throws IOException { IntWritable, Text, IntWritable> { IntWritable> output, Reporter reporter) throws IOException { sum += values.next().get();         } output.collect(key, new IntWritable(sum));     }  } public static void main(String[] args) throws Exception { JobConf conf = new JobConf(WordCount.class); conf.setJobName("wordcount"); conf.setOutputKeyClass(Text.class); conf.setOutputValueClass(IntWritable.class); conf.setMapperClass(Map.class); conf.setCombinerClass(Reduce.class); conf.setReducerClass(Reduce.class); conf.setInputFormat(TextInputFormat.class); conf.setOutputFormat(TextOutputFormat.class); FileInputFormat.setInputPaths(conf, new Path(args[0])); FileOutputFormat.setOutputPath(conf, new Path(args[1])); JobClient.runJob(conf);  }   Output $ bin/hadoopdfs -cat /usr/joe/wordcount/output/part-00000  Bye 1  Goodbye 1  Hadoop 2  Hello 2  World 2    - Apache   You can always make the Map Reduction on platforms and languages of your choice like Python or Golang. If you are adopting the framework, though, you should always make a note to check the support the framework has for the language of your choice. In case the scripting interface is undergoing a change like Angular or PHP.   Getting used to the ecosystem For all the users this is a tricky bit even after getting through the commands on the VM. You can follow any follow through on setting up the standalone, but the components you should be going through is still up for debate. My recommendation is to get going with Hive as its tabular sequences and querying is very much similar to SQL, only with increased functions for data summarization. You will also be needing Sqoop if you plan on using multiple tracks or parts of data for your BI solution. Typically if you are working with E-commerce, then your data sources may be multiple I know for a fact that porting data from Oracle DBs or MySQL DBs is not an easy task. Oracle DBs are particularly difficult to port for most solutions cut components like SQoop make the task a tad bit simpler. HBase, Ansari, Solr,etc. are also names you should keep in mind. Of course, you will have your favorites but go through as many of components as possible if you want to maximize Hadoop's usage fully. Happy hunting!

Swift Playgrounds App - Effortless Way To Learn Coding

Apple introduced Swift Playgrounds, a new app to learn swift coding for iPad. It has been designed to make the learning of swift more interactive and fun.Swift can be described as the powerful programming language created by Apple and it is being used by the experts to build many world class apps. Swift Playgrounds app mainly focuses on making the learning process of Swift easier. With this effort, Apple has moved one step towards making the new generation learn and write Swift codes. Swift Playgrounds has programming lessons where students can learn coding by sharpening their skills with many puzzles and challenges. Built-in templates are added in the app encourages the users to create real programs and share it with their friends using emails and even posting it online. These programming courses and training are highly useful for the students in learning the core coding concepts such as looping, functions, variables and many others. Students get the confidence of building the codes and ultimately ends up sharpening their skills. Developers and Educators also gets an option to use Xcode for creating their own challenges for the app. Apart from lessons, Swift Playgrounds has a lot to offer an aspiring developer. It has been designed in such a way that developers can show their creativity alongside build and modify the codes whichever way they want. The real Swift code is being used in the Swift Playgrounds and this makes it easier for the developers to directly export the codes to Xcode, an integrated development environment (IDE) containing a suite of software development tools developed by Apple). Exported codes are then used to create programs for iOS and macOS. Empty Playgrounds documents and built-in templates are two options provides for the development and writing codes in Swift Playgrounds. The multi-touch feature is supported in Swift Playgrounds app and with the help of this entire program can be created with only a few taps. It has been made pretty simplified as the editing can be done on a single tap with a pop-over keyboard, now color can be displayed only by choosing their codes. Dragging and dropping of code snippets saves the user time code and yet powerful enough. Undoubtedly, Swift Playgrounds is here to make a difference and revolutionizing the way coding is done so far. It's preview released with the iOS developer preview and it will be available to use with iOS public beta in July. It is compatible all the later running iOS 10 apple products. The final version of Swift Playgrounds will be soon available in the apple store for free. Getting familiar with Playgrounds fundamentals To begin with, it is required to download XCode , an integrated development environment (IDE) containing a suite of software development tools developed by Apple for developing software for OS X, iOS, WatchOS, and tvOS. Now after downloading and setting up we are all set to code with Swift. Getting started Xcode is free to download from App Store and it requires a Mac computer running OS X 10.9 or later. Once downloaded, open Xcode and select “Get started with a Playgrounds.”                                  Xcode has been empowered with Swift programming language,and it is a great place to explore and have fun with the codes. The playground has the feature of producing real-time code results and this makes it more interesting to work with. Apple has also come up with a very interesting comment for it, “a place where people can have fun” .                                    The editor looks very simple as it appeals everyone to play and have fun while writing codes. It has been made so simple that anyone could understand it very easily and quickly. It has been separated into two different panels, the left side is for writing and editing the codes while the right side shows the results of the codes. Swift variables and constants var are used to declare variables in Swift. let is used to declare constants in Swift. We should know some fun facts about  Swift as it uses any Unicode character such as emoji’s , hanzi, katakana to declare it as a variable. Variable type Swift is a very flexible language as it doesn’t require any type annotations to understand variable’s type. If a user wants he can declare variable type explicitly. This can be done by changing the variable declaration with . Here we declare a string: var greetings: String = "Hey!" If we want to add something: var greetings: String = "Hey!" greetings  = greetings + “listen” This concatenates two words and generates output as “Hey! Listen” Printing   We use println() for printing something to the console. The keyword is superfluous but it is necessary to know for an iOS app developer. simple example: println(“It’s awesome to use Swift. M loving it!”) Comments Swift Playgrounds comes up with different ways to comment a statement in the code. // This is a single line comment. /* It’s gone …All the things writtenSeriously  */

6 Reasons: Why Phonegap is amazing For Small business?

In this mobile world, developers are taking a keen interest in targeting mobile users as their numbers are growing rapidly. The statistics below shows the total number of mobile phone users globally from 2013 to 2019. In the next following years, the number of users will increase forecast to 4.77 billion. This is happening all due to the increment of smartphones. More the user's purchase smartphones, downloading of apps will be more.   Today, you can find apps targeting every area of life, business and pleasure, including marketing, games for adults and kids, medicine, health and fitness, travel, beauty, and more. We all know how older members of our family cannot move much due to their age and health. So we try our best to provide them with everything but at times when they are suffering, you sometimes don’t understand why it is happening. The world of mobile apps has grown to a new level that you will be surprised to know that developers have even created smart apps that can test people for mental ailments. There are even apps to contact a doctor directly or find the available doctor in your area and much more. These apps have made our lives much easier. Developers due to fierce competition in the market have to come up with unique ideas that no one has thought yet. They are keen to try different kinds of software for developing variety in their mobile apps and compatible with all mobile devices. They all consider using PhoneGap. What is PhoneGap? PhoneGap is also famous by the name of Apache Cordova. PhoneGap is the best mobile application development framework. It is the creation of Nitobi, but later on was purchased by Adobe Systems in 2011. They rebranded it as PhoneGap. PhoneGap is an open source and very collaborative software. By using PhoneGap, developers can develop native mobile applications for any mobile device just by utilising JavaScript, HTML, and CSS without losing the features of a native app. The developer writes native apps for a particular platform or device. Instead of relying on one platform, driven APIs (Application Programming Interface) like iOS. PhoneGap solves a huge problem faced by the developers of today by offering standard-based web technologies to create a link between mobile devices and mobile applications. They consider PhoneGap a great fit for the enterprise mobile apps since the code runs on any platform rather than one. It can also bind the codes relying on the platform according to the device. Want to know why they consider this software. Here is a list of reasons why PhoneGap is considered as free for commercial use: 1.Acts as a Wrapper PhoneGap acts as a wrapper mean that it wraps around the device’s web view, making it convenient to create a single base code for all four platforms.It provides an advantage for all the existing skill of developers and designers.  PhoneGap application is combined with inbuilt browsers that already installed in it. 2.High APIs One of the best features of PhoneGap is that it can easily access any device’s hardware as its accelerometer, camera, address book, etc. With this, the developed apps on PhoneGap can easily make use of the properties of the resources of a device without compromising on quality and user experience. 3.Two fold benefits Using PhoneGap is a win-win situation for all stakeholders. With this software, developers gain a lot by spending little in effort and cost to design a fantastic app. An app created on this system works on all the platforms, providing the business with many profits. The apps created through PhoneGap are easier to market and distributed via app stores. 4.Works on basics As a developer using PhoneGap, you will not need extensive knowledge about mobile programming. PhoneGap works on primary languages like CSS3, HTML5, and JavaScript. Most of the developers already know about these very common browser-based skills.  Hence, business owners can put their tech teams to work, and start developing an original app. PhoneGap acquires different languages; you cannot use this app properly. In case you want to receive training in PhoneGap, you can easily get them online. Try the latest and innovative Phonegap online training classes that are sure to benefit you in your career. 5.PhoneGap & Cloud PhoneGap is a complete package. It takes away the pain of compiling apps altogether. You can easily get app-store ready apps without the need to maintain native SDKs (Software Development Kit). PhoneGap built service offers to do the work for you by compiling your app and provides you with a cloud storage. Whichever application you are designing, it will have the most up-to-date SDK for the platform that you have set the target. If you'd like your application to work on different platforms, then you must choose PhoneGap application development for your apps. 6.What developers prefer? Regardless of many application development frameworks available in the market, PhoneGap followed by Sencha Touch and Mono holds number 01 position. 23% of the developers prefer PhoneGap. PhoneGap is likely to stay on top for a long time. PhoneGap is also compatible with toolkits of JavaScript like jQuery Mobile, Sencha Touch, and Dojox Mobile. PhoneGap is the latest software where you can design and code your apps without worrying about their compatibility with the mobile devices. This software has built-in features that include an unlimited cloud storage. Any other software does not offer this kind of benefit. Thus making it advantageous for small business. You would not need to spend any more money on different software, just get PhoneGap and all your worries will be over.

Getting The Bot To Do New Things – Android Development

Did you ever have a trivial problem with your phone and thought of an ingenious idea to fix it, but didn’t know how? That’s why Google bridged this gap between the user and their device with the introduction of its operating system -Android. With Android, users could easily develop applications to run on their mobile devices and share it with other users on the Google Play store. Android Development gave users the freedom to be creative and also to add a few extra features that they always wanted on their phones. Some problems faced over the years with Android development Numerous versions In 2010, Android had released Gingerbread, (version 2.3-2.3.7) which was an arduous task to develop the applications for this version. It occupied close to 10-15% of market shares at that time. Then, in 2011, Google released Ice Cream Sandwich, (version 4.0) which was completely different from Gingerbread and with new UI elements, new APIS for hardware, new screen densities, etc. This made things a little more difficult for developers as it led to more bugs and fixes, which in turn expanded the time frame to create an application. User Interface Then came iOS, developed by Apple. Though Android was better than iOS in numerous ways, there was one category where iOS won hands down, and that was its User Interface. The iOS applications were much more colourful, interactive and animated compared to their Android counterparts. The Current Android Scene Currently, Android is being used in almost all gadgets in the market and these numbers are increasing by the day. The latest gadgets using Android OS are smart watches, tablets, cameras, televisions, cars, etc. The latest Android version is Marshmallow (version 6.0), which was launched in the 3rd quarter of 2015. Marshmallow is quite exceptional compared to its predecessors on various parameters, such as more detailed app permissions, improved battery life and Google’s “Now on tap.” Another important modification was the stabilization of Android Studio, one of the most popular Integrated Development Environment (IDE). There were many complaints from the developers regarding the Eclipse IDE which resulted in many developers migrating to the more stable Android Studio. Android Studio stands apart due to the following reasons: Unit test You can define your unit tests as different classes and use them while testing your applications. The errors displayed will point out the bugs in your code before the production stage. Speed A project will take about 1 or 2 minutes to launch in Eclipse and it takes less than 30 seconds to launch in Android Studio. Gradle Gradle is a vital project automation tool which replaced Apache Ant. Almost everything can be automated using Gradle. The applications can be divided into different flavours, the build numbers can be incremented and external dependencies can be defined, among other functions. The quality and quantity of smart phones released in the market have improved significantly over the years. This has led to more affordable smart phones to fit any budget. Future of Android? So what does the future of Android look like? Looking at the rapid pace of development in the past few years, a few predictions can be made about the future of this widely used operating system. Everyone involved with Android- Google, OEM manufacturers, and developers have realized that they now have a stable operating system with countless applications, used by millions of users. Their next goal is to make Android simpler and speed up the application development process. One of the ways to do this would be by introducing a new programming language to develop Android applications. Java is an exceptional programming language but, it has its flaws. Not to compare, but Apple released a brand new programming language, Swift, which combines the best features of languages like Python, Ruby, and C#. This makes life simpler for a developer and an application can be developed much quicker than while using the traditional methods.

8 Difficult Situations Java Programmers Can Get Themselves Into During A Project

The world runs on Java. Ok, not exactly, but when a programming language has 9 million developers (equal to the population of Sweden), its popularity speaks for itself. It revolutionized software development with its “write once, run everywhere” paradigm. Java development is correlated with the ubiquity of Java Virtual Machines. As per estimates, 97% of Enterprise Desktops run Java. However, Java developers also face issues. Here is a list of top 8 difficult situations Java programmers can get themselves into during a project: 1. Lines and lines of code:   To accomplish any task in java requires writing a lot of lines. For example, in python, printing “Hello world” is a one line program. In java, it takes a minimum of three lines and 4 curly braces. Quick prototyping is difficult when a language requires so many lines of code to accomplish even the most basic tasks. Hence, the language is not very conducive for a swift and dirty implementation of an idea.  2. Variable mêlée:  Like any God fearing programmer, you religiously follow the getter-setter convention for class variables, but your colleague doesn’t. To access the variables in his class, you need to actually type the name of the variable. And now you are mixing his convention with yours, and feel like tearing your hair out. 3. Improper Exception handling:  A hundred lines of code where you open files, persist records into the database, try to access elements in an array, have multiple ‘for’ loops, and parse strings. All those lines of code inside a single try catch block with the log entry being “Error”. When the code crashes during runtime, you realize your folly. And you are not happy. Because now you have to filter the cause of the crash from a list of probable causes. 4. Eclipsed:  Due to its widespread usage, Eclipse IDE has become synonymous with java based development. Most programmers use it because of its unmatched support and array of helpful plug-ins. But the dependency on Eclipse means that productivity suffers if we are not able to configure the project on the eclipse. 5. Extensive Java libraries:  An elaborate collection of libraries is one of the most attractive features in java. If you can think of it, a library to accomplish it exists. However, these libraries can also pull down the performance of your code. In many cases, the libraries are not optimized for performance. They carelessly instantiate objects when the same could be accomplished by using primitive data types, hence dragging the performance down. 6. Java garbage collection and memory leaks:  Java Virtual Machine (JVM) has inbuilt garbage collection mechanism which is one of its most crowning achievements. However, that might make a developer complacent, and lead him towards “java.lang.OutOfMemoryError”. Sometimes you have to increase the memory allocation for the JVM, but several other times, the developer might have ended up using a lot of temporary objects and not de-referencing them once done.  It could also be caused by improper usage of static variables, or not removing elements from Java collections like Maps and Vectors. 7.    Version Mismatch:  You developed your application using Java 7, the production environment has Java 6. And now we have a list of UnsupportedClassVersionError staring at our face. 8. Java web, a no-no:  Java is bad for web development. Especially, the front-end part. Java is considered bloated, heavy and the applet revolution it promised never happened. Problem or not, at the end of the day, a Java programmer will most definitely have the patience, skill, and determination to get out of a tight spot. If all else fails, a new solution might just get typed up! Now you know why JAVA is important and how you can be the kind of JAVA developer companies are looking for. If you are looking for someone to train you on JAVA, ZeoLearn offers JAVA course that works under the supervision of experienced professionals within the niche.

The Hiccups In Android Application Development

Is there anything worse than a technical glitch or screen freeze when you’re in the middle of completing a banking transaction or about to get your highest score? Now imagine if you are responsible for that particular situation. Android developers sure have it tough in this highly demanding and growing field of creative media and software. And if you happen to be one, here is a list of the possible problems you might face at one point of time or another: The Learning curve Unlike other platforms, coding for Android requires the programmer to have a working knowledge of various languages like Java, XML, JSON, which in itself requires quite an amount of effort and dedication.  Also, unlike coding for computers, the Android platform supports touch controls and gestures, which take the complexity to a whole new level even with the assistance of the available code libraries.  A Fragmented Market It is difficult to create an app that would suit all the different screen sizes and work smoothly on all devices. In certain cases, it will be hard for the developer to find a particular phone even for testing purposes because it won’t be in sale anymore. But, there will still be users out there who use that model and the developer has to make sure that his/her app works on that model too. Limited Access to the Latest Version When creating an app, it is necessary to make sure that the app not only works on the latest version of Android but, also on the older versions. This is because very few manufacturers release the latest official Android update for their phones in a timely fashion. In some cases, updates are issued months, sometimes a year, after Google introduces the update in the market. Hence, it is necessary to cater to these users as well when creating the app. The Revenue Disparity As compared to iOS, Google focuses more on providing free apps to its Android users. Hence, as a developer, it is harder to earn higher revenue when developing an Android app. There have been certain instances where an app earned close to 10 times more revenue on iOS than on Android for the same number of downloads. Manufacturers Manipulations Android phone manufacturers at times have a variety of suppliers for their hardware components. Certain Samsung phones will have an issue with the camera, HTC phones might have an issue with the microphone, and only a few manufacturers support the call recording feature. To top this, various manufacturers modify the android source code and release their own custom ROMs with their handsets along with proprietary software, which might be in direct competition with what the developer is working on. It is difficult to successfully develop an Android app suitable for all Android phones with each manufacturer having a different issue or bug. Watch out for Battery Life One important aspect that most Android app developers tend to overlook is the battery consumption of the Android device. Developers get their programming skills by coding on computers which were connected to a main power supply. Hence, there is not much focus on the energy consumption of devices. In a recent study, it was discovered that maximum energy in Android apps was expended on network input/output functions. In free Android apps, 65-75% energy was spent on advertisement modules. Now, the challenges may seem quite exhaustive but Android development is one of the most popular career paths for software developers across the world. Ideation, creativity, technical skill and aspects of consumer behaviour and research are all brought together when one is developing a high-grade Android app. And the high you get once you have created your very own aesthetic, user-friendly and smooth functioning app makes all the work you put in, worth it.  Now you know why Android is important and how you can be the kind of Android developer companies are looking for. If you are looking for someone to train you on Android, ZeoLearn offers Android Development courses that work under the supervision of experienced professionals within the niche.

Programming Concepts Every iOS Developer Should Know

When people talk about life altering inventions today, they do not talk about invention of steam engine, light bulb or the wheel anymore, they talk about life altering mobile applications/software which have influenced our daily lives in such manner that imagining our lives sans these inventions is impossible.One such revelation in the modern era has been the introduction of an array of “i” products ranging from iPhone to iPod to iPad and so on. Apple is now an indispensable part of millions of people around the world with people queuing up for hours before the launch of an Apple product to be the first ones to grab their dream gadget. So what makes Apple products so sought after? The Operating System!iOS or originally the iPhone OS is a mobile operating system created and developed by Apple Inc. and currently powers many of the company’s hand held devices.Apple Inc. provides opportunity to every individual to become an iOS developer with the Apple Developer Program to reach customers around the world. However, needless to say, becoming an iOS developer requires immense knowledge and technical understanding.Becoming a successful iOS developer requires fundamental understanding of programming concepts.Following is the list of fundamental programming concepts that are essential for an iOS developer: 1. Xcode and interface builder Xcode is a powerful Integrated Development Environment (IDE) provided by Apple inc. for free of cost and is the most important tool for building an iOS App. Xcode helps manage the content of a project and works as a code editor with code auto completion assistance to type codes without typos.Interface Builder is a graphical tool inside of Xcode to build interface of your app in a visual way. 2. Cocoa touch Cocoa touch is a UI framework for building software programs to run on iOS. 3. Table Views Table views allow user to navigate through hierarchically structured data and give an indexed view of items. 4. View Controllers View controllers constitute the skeleton of every iOS app. View controllers in iOS also manage auto rotation and perform resource management, receiving memory warnings from the OS when the memory starts to fill up. 5. Storyboards and Segues Storyboard can be used to visually lay down the flow of screens of your app and the transitions between them in Interface Builder. As the size of the project grows, multiple storyboards can be used to contain all the flow of the app.Segues can be used to connect view controllers to each other inside story boards. 6. Auto Layout Auto layout was introduced by apple to facilitate creation of dynamic interfaces that adapt to every screen size and orientation allowing the app to run not only on iPhone but all other Apples devices. 7. Key value coding and Notifications Object on an iOS communicate one to one through the common design pattern of iOS. There are cases where two different kinds of communications are needed. For this, iOS two different mechanisms. Key Value Observing: The mechanism allows objects to be notified of changes to specified properties of other objects. Notifications: Notifications work through notification centres, which manage sending and receiving of notifications. Any object that want to register as an observer for a specific notification posted by other objects, does so through a notification centre. Becoming a developer is a complex process, which demands concrete technical knowledge about programming concepts. In addition to the key programming concepts mentioned above, every developer should educate themselves about other critical concepts, which are essential to become an iOS developer.
