For developing mobile application, JAVA is accepted as one of the best programming languages. It is an object- oriented language developed by Sun Microsystem in 1995, and became the most prominent language for programming within 20 years.

How does the JAVA language work?

In other coding or programming languages, the code is first translated by a compiler into instructions, while in JAVA instead turns code into Bytecode, which is then interpreted by software JRE (Java Runtime Environment).

Why is Java the best programming language?

Java is easy to learn, the language has fluent English-like syntax and less mysterious characters. Java has rich API, xml parsing, database connection, networking, utilities and provides almost everything that a developer can expect. It is also open source and available free. Eclipse and Netbeans are the powerful tools that brings life to JAVA script

Interaction of JAVA and Android Phones 
Android have succeeded in keeping JAVA on the forefront in last couple of years. JAVA gives the best option for development of mobile applications that are based on Android, as Android consist of its own APIs and JAVA libraries. So, for Android applications, you use android APIs as well as JAVA to write code for Android apps.

These apps are called as native apps, as it is developed by using native tools and libraries. You can also code in other language as well but you need a framework to convert into native app for that API. To execute the programming files, Android does not use JVM (JAVA Virtual Machine) but instead uses DVM (Dalvik Virtual Machine), which is not a true JVM. So, to execute the files it has to convert into DEX format and then bundled into Android Package (APK).

For mobile application, JAVA has specially designed J2ME (JAVA to micro edition). All J2ME application must have main class that is derived from a special class called MIDlet. The standard JAVA runtime environment for these devices is provided using (MIDP) Mobile Information Device Profile and Connected Limited Device Configuration (CLDC). To write J2ME applications, you need the JAVA platform micro edition SDK (software development kit) and IDE, which can be Eclipse or Netbeans. But to develop Android application, JAVAmidlet has to convert into Android apps and for that, tools like J2Android is used. This tool can convert any JAVA midletinto Android apps.

There is a question raised on the JAVA performance and future application, butJAVA gives the platform to promising language based on JVM such as Scala and Clojure. And with the introduction of new version, JAVA 7 will become more efficient.

In conclusion, JAVA is the best choice for mobile developers working on Android applications because it is convenient and relatively easy to use.

We must thank again one of our loyal readers for helping us realize the importance of this follow-up. The truth is, key changes in such a critical technology deserve continuous coverage. Furthermore, the “update of the update” —i.e., PHP 7.2— sets new challenges and opportunities, in and beyond Moodle.

PHP 7.2 is not the significant departure from PHP 7.1 that PHP 7 was from PHP 5. But there are incompatibilities from 7.1 to 7.2, as well as deprecated features.

But if there is one point to get across, is that PHP 5 and 7.0 are a thing of the past. The only actively supported version of the last branch is PHP 5.6, which is no longer actively developed and will stop receiving any kind of update, including security, by New Year’s Eve. PHP 7.0 will receive security support until December 3rd, and PHP 7.1 will stop active support until December 1st.

In the case of Moodle, the situation is not as dire as in other PHP-based systems, but there is some cause for concern. PHP 7.2 is compatible with Moodle 3.4 and 3.5 only, which according to the official stats cover some three fifths of registered active Moodle sites.

Hinkelman’s list

Please list the major changes in PHP 7.2 that might affect Moodle.
The bottom line is that not doing the migration will make the sites more vulnerable. But the mandatory switch should have some visible benefits including speed, smoothness in 64-bit machines (the increasing majority of them), and a decrease in the fatality of running into code errors. PHP 7.2 is designed to make the code more flexible and errors more manageable and less consequential.

Regarding the new features coming in PHP 7.2 compared from PHP 5, the list is long and highly technical. But final uses should count on a more secure and reliable system, and depending on the developer and functionality, better plugin performance.

What changes are likely to affect custom plugins, such as activity modules, themes, question types and blocks?
Other than ensuring compatibility, plugins and core features do not need to make radical changes to their code. But developers are welcome to study some of the key new features and decide whether it enhances the quality and performance of their programs:

  • Convert numeric keys in object/array casts: It expands the uses and access of data in arrays.
  • Counting of non-countable objects: When a piece of data that is not “countable,” a warning will appear next to the result of using the count() function (1).
  • Object typehint: Functions can now request that variables are objects of any kind, as long as they are objects.
  • Migration Hash Context from Resource to Object: A “Hash Resource” is a type of data for certain extensions, designed for cryptography. Before PHP 7.2 it could not be used as an object, but now it can.
  • Argon2 Password Hash: Developers can now safely store passwords using this “superior” algorithm, winner of the latest Password Hashing Competition.
  • Deprecate (then Remove) Mcrypt: The decade-old Mcrypt extension to encrypt data (not just passwords, like Argon2) is out the door. It is unlikely developers today use it.
  • Make Libsodium a Core Extension: Mcrypt’s demise gives way for Libsodium, which is more robust and is actively developed.
  • Improved SSL / TLS constants: It makes it easer to add a security layer to process involving information transfer between two systems.

Another, even more delicate issue developers (and hardly anyone else) involves the compatibility of frameworks they use to streamline PHP programming. Zend, one of the most popular, became compatible with PHP 7.2 only a few months. Developers who use Zend must upgrade both PHP and Zend to ensure compatibility.

What problems did HQ have to solve to get MoodleCloud working on PHP 7? Maybe you should interview an HQ developer about this, and get their advice for institutional upgraders.
We do not have an announcement on interviews at this time. Stay tuned!

Should schools wait to upgrade to Moodle 3.5 for a year or so, because PHP 7 is such a major change?
In short, no. PHP 7 has been around for almost 2 years. In tech time, it is plenty for both plugin and Moodle HQ developers to get acquainted and make the switch. However, the ideal and actual scenario might vary. It is estimated that 57% of the internet still uses PHP 5.6 and 7.0. You can thank WordPress most of all for this.

PHP 7 might come with new things to learn, but it is designed to make PHP programming more manageable.

Representing a group of successful biocontrol agents for various pest fruit flies, a parasitic wasp genus remains largely overlooked. While its most recent identification key dates back to 1969, many new species have been added since then. As if to make matters worse, this group of visually identical species most likely contains many species yet to be described as new to science.

Having recently studied a species group of these wasps in Central Europe, scientists Fabian Klimmek and Hannes Baur of the Natural History Museum Bern, Switzerland, not only demonstrate the need for a knowledge update, but also showcase the advantages of modern taxonomic software able to analyse large amounts of descriptive and quantitative data.

Published in the open access Biodiversity Data Journal, the team’s taxonomic paper describes a new species – Pteromalus capito – and presents a discussion on the free-to-use Xper3, developed by the Laboratory of Informatics and Systematics of Pierre-and-Marie-Curie University. The software was used to create an openly available updated key for the species group Pteromalus albipennis.

The fully illustrated interactive database covers 27 species in the group and 18 related species, in addition to a complete diagnosis, a large set of body measurements and a total of 585 images, displaying most of the characteristic features for each species.

“Nowadays, advanced computer technology, measurement procedures and equipment allow more sophisticated ways to include quantitative characters, which greatly enhance the delimitation of cryptic species,” explain the scientists.

“Recently developed software for the creation of biological identification keys like Xper3, Lucidor Delta could have the potential to replace traditional paper-based keys.”

To put the statement into context, the authors give an example with one of the studied wasp species, whose identification would take 16 steps if the previously available identification key were used, whereas only 6 steps were needed with the interactive alternative.

One of the reasons tools like Xper3 are so fast and efficient is that the key’s author can list all descriptive characters in a specific order and give them different weight in species delimitation. Thus, whenever an entomologist tries to identify a wasp specimen, the software will first run a check against the descriptors at the top, so that it can exclude non-matching taxons and provide a list of the remaining names. Whenever multiple names remain, a check further down the list is performed, until there is a single one left, which ought to be the one corresponding to the specimen. At any point, the researcher can access the chronology, in order to check for any potential mismatches without interrupting the process.

Being the product of digitally available software, interactive identification keys are not only easy, quick and inexpensive to publish, but they are also simple to edit and build on in a collaborative manner. Experts from all around the world could update the key, as long as the author grants them specific user rights. However, regardless of how many times the database is updated, a permanent URL link will continue to provide access to the latest version at all times.

To future-proof their key and its underlying data, the scientists have deposited all raw data files, R-scripts, photographs, files listing and prepared specimens at the research data Zenodo, created by OpenAIRE and CERN.

Microsoft has developed open-source software for crafting artificial intelligence models. But in recent months, the company has changed course, opting to work more closely with Facebook and contribute to the development of Facebook’s own flavor of free AI software.

Microsoft hasn’t made a big deal about the change. But it reflects a willingness to back software that comes from other major technology companies, rather than focusing only on its own platforms.

Google is the company behind the most popular open-source AI software, TensorFlow, which became available in late 2015. Microsoft put its Cognitive Toolkit, or CNTK, software on GitHub and gave it a more permissive open-source license in early 2016, and Facebook came out PyTorch, its answer to TensorFlow, later in 2016.

The Microsoft system has strengths, particularly for building speech recognition systems, but PyTorch has gained adoption quickly and has some interesting technical features of its own, Microsoft’s chief technology officer, Kevin Scott, told CNBC in an interview this week.

Last year, Scott met with Facebook’s chief technology officer, Mike Schroepfer, and decided it would be good for the companies to attempt to “defrag some of the complexity” in the ecosystem of software that people can use to train AI models. In Sept. 2017 Facebook and Microsoft together introduced ONNX, a piece of open-source software for exporting models trained with one AI software framework, like Microsoft’s Cognitive Toolkit, so that they can be used to make predictions with other frameworks, like Facebook’s PyTorch.

The reality is there are just too many AI frameworks out there, said Sai Soundararaj, cofounder and CEO of AI start-up FloydHub. The start-up’s cloud service has supported Microsoft’s Cognitive Toolkit, but it hasn’t gotten much use from customers, Soundararaj said.

Microsoft hasn’t abandoned Cognitive Toolkit, even as it’s focusing more on other projects. The Microsoft software still receives updates.

But the direction is clear. “The momentum of community, really, is around PyTorch and TensorFlow, and so that’s where were throwing the bulk of our emphasis,” said Eric Boyd, Microsoft’s corporate vice president of AI platform. “Having community adoption is hugely important.”

The move around Cognitive Toolkit is part of a recent trend at Microsoft to embrace technology from outside the company. It has embraced Linux, making it accessible from within Windows 10 and creating a Linux version of its SQL Server database software. It has reduced its efforts around Windows for mobile devices and ramped up development of applications for Apple’s iOS and Google’s Android. And Microsoft stopped developing its own big-data software, Dryad, and threw its support around the Hadoop open-source tools.

The Honor Magic 2 got official at the end of last month with a mechanical slider design that lets it reach an 84.8% screen-to-body ratio. It’s a system that’s similar to that employed by Xiaomi’s Mi Mix 3 and it enables an almost entirely bezel-less look on the front.

The Honor Magic 2 is now receiving an intriguing software update. If you’re lucky enough to own one you’ll get a notification soon (if you haven’t already), which will prompt you to install software version (C00E129R1P18).

This brings with it an unexpected switch from Huawei’s EMUI to something called Magic UI 2.0, which the company describes as being “a next generation AI-powered system”. It’s the first time we’ve seen Huawei sub-brand Honor depart from using EMUI in its smartphones.

Since this is its current aspirational flagship device though, it makes sense it would get a reimagined interface. You should apparently see a brand new color scheme, new icons and fonts, all part of “a new magical journey with Magic UI 2.0’s stylish interface, AI capabilities, and evolving YoYo smart assistant”.

The November 2018 security patches from Google are also built into the update, which will require a 214MB download.

Imagine one time you came up with a great idea to create a website for your company. The first step to take in this case is to hire a web development team of professionals that can fit the project’s objectives. The selection of the project team is as important issue to plan as the website development cost and budgeting. So, don’t neglect it.

It is mistaken to think that a couple of programmers is all you need to build a site. If you want the future website to be a powerful tool for adding clients and building a customer loyalty, you should also think through digital marketing. Below, we’ll discuss the basic roles in web development and digital marketing teams.

Common structure

So, you’ve contacted a web dev company to build your website. Some companies can suggest a ready-made team, but others can not. The second scenario is common for narrowly focused or recently established companies.

The team structure in different companies can vary. A common web development team includes a UX/UI designer, a couple of Web developers, a Project Manager (PM), a QA Engineer, and a Requirement Analyst (RA).

To promote the future project, this team can also consist of an SEO specialist, a Content writer, and a Marketing strategist. Now let’s get a closer look at each role.

Requirement analyst

The first step of the development process is a planning. At this point, you are interviewed by the requirement analyst. It is a person who analyzes your project ideas and then turns them into a technical specification for designers and web developers.

The main task of this person is to get as much information about the future project as possible. For instance, website main functions, target audience, and desirable architecture.

After it, RA carefully analyzes the obtained information. They estimate the approximate cost of website development for you and then establishes technical documentation.

Project manager

After RA has struck a deal with a client and established technical documentation, it’s a project manager’s turn. PM is a person responsible for delivering the product on time. It is a key person that controls the work ow the whole team. The main PM duties include:

  • Communicating with clients. Are you dissatisfied with something or decided to add a new feature? So it is the person you need to contact with. On your request PM can gives an information about progress. In turn, they contact you when the team needs an additional information about the product.
  • Planning resources. After getting a technical documentation from the requirement analyst, PM estimates how much time and money are needed to accomplish this task.
  • Controlling the development process. PM assigns responsibilities among team members. During the development process, PM monitors whether workers accomplish their tasks on time.
  • Drawing up the project plan. This document includes the full information about timelines, resources, and budget.

UI/UX designer

The designer knows exactly what makes a good website. Two types of design you may encounter are user experience (UX) and user interface (UI) design. In most companies, one person is responsible for both of them.

At first, this specialist thinks through user experience, which is extremely important for building trust towards your website. They define the target market and tries to predict user behavior. Then designer identifies difficulties users can face while using your future website. On the basis of this information, a designer makes a wireframe. It is a skeleton of your future website that shows the size and placement of each page element. In case you like the wireframe, it is high time for the designer to think about UI.

While UX design is focused on the structure, UI design deals with visual appearance. It is the most important step on the design process. The designer selects the color scheme, icons, and fonts. They get the sample version of the final product called a prototype. Depending on the particular situation, you may have an opportunity to interact with a prototype, or it can be static.

To meet special requirements, you may also need a graphic designer, who can create a logo, custom font or illustration. The motion designer is also optional, this person creates animations on the website.

Web developer

So, you accepted the designer’s prototype, and then finally you get to the most crucial process. The process of transforming the designed prototype into lines of code. There are two parts of web development:

Front-end or client-side development. It is everything you see on the site: buttons, headlines, login form and so forth. Commonly, the front-end developer must know:

  • HTML5, which is responsible for the structure of a website;
  • CSS is a programming language that describes the style of your website;
  • Javascript;
  • CSS Preprocessing. It stands for using preprocessors like LESS and Sass. They can make it easy and fast to change font or color scheme of your website in case you want to modify the project;
  • CSS frameworks like Twitter Bootstrap;
  • Javascript frameworks like vue.js and react.js;
  • Responsive design. With responsive design, you can be sure that your customers will look good no matter you customers visit it via PC, smartphone or tablet.

Back-end development focuses on functionality requiring interactions with the server. For instance, you have a beautiful subscribe form. The button can change a color when a user hovers a cursor over it, but it isn’t useful without a few lines of code under the hood. Back-end developer writes a script which sends your information to the server and checks it.

Their common duties are integrating a CMS system, implementing security standards, managing database and writing server-side scripts. There is a big list of programming languages for this objective. For instance, PHP, Python, ASP.NET, SQL, and others.

Some companies can offer you, full-stack developers. They can carry out the duties of both previously mentioned specialists.

QA engineer

The last but not least role. The duty of QA engineer is to find bugs in a product before a website user does.

The work begins when the QA engineers get information from the requirement analyst. On the basis of this data, they create a testing plan. Then these specialists receive each version of the product from programmers and test it. The project must correspond requirements, fit customer needs and contain no bugs.

When this specialist finds a bug, they write a bug report and sends it back to developers. Then the developers send the next version with fixed bugs and QA engineer checks whether this bug has finally been fixed. To get the full picture, QA engineer tests a website on different platforms and browsers.

QA engineers also test website design. They check whether colors, size and other features of website elements correspond to requirements. In case something is wrong, QA engineer sends a bug report to a designer.

Now you know the most common team structure. But a simple web development is not enough if you want to get profit from your website. It is quite easy for your project to get lost in an endless number of websites. After the website has been released, you need to make as many users as possible know about it. Especially, when you sell goods online. And here the digital marketing team comes in handy.

Digital marketing team

We’ve already talked about common roles, now let’s consider each role more closely.

SEO specialist

SEO stands for Search Engine Optimization. The main duties of SEO expert include:

  • Analyzing metrics and traffic of a website. This professional collects and analyzes the information about how many users visit your website every month.
  • Optimizing website. Each search engine has a list of requirements. When the website meets these requirements, the search engine puts it on the top of search results. So more people can find your website. On the basis of requirements, an SEO specialist gives recommendations about changes in website architecture.
  • Analyzing the market. The SEO specialist also defines your rivals and discover their weaknesses, strengths and promotion strategy they have chosen. Additional duties of SEO specialist depend on the purpose of your website.

Content writer

The role of content is often underestimated. Sometimes business owners delegate the task of content writing to the person who is not a professional writer. And as a result, get the low conversion rate.

Content specialist or content writer accomplishes all text-related tasks. This person writes descriptions for products or services, articles to your blog and so forth. They collaborate with SEO specialist to optimize text for search engines. The main duty of this team member is to write easy-to-read copies tailored to your business needs and optimized for searching engines.

This person analyzes the target audience and in accordance with the obtained information finds the best way to persuade clients to buy your products or use your services.

Quality, innovation and speed are what this Kollam-based design agency ‘B4Creations’ is focused at. Easy to find, stylish, quick loading is all that you will find in a website created by this agency. This company founded by Ayyappan Sreekumar, Sahil Abdullah and Bilal Muhammed is probably the only web development company with a Google-certified partner, a YouTube partnership, Facebook partnership and giving digital marketing services at affordable rates.

In 2007, Ayyappan, with a passion for learning web development, started a blog. He started learning more about web development and how different techniques can be used to develop interesting websites. “I started creating websites for shops and organisations and got good reviews.

With this experience, I became a web developer,” said Ayyappan, the director of B4Creations.Ayyappan’s next challenge was to study the web developing techniques on Facebook. It was at this that he came to know about Sahil who was much experienced in this field. Bilal was doing events then. In 2012, the trio got together and started a  company ‘B4Creations’ with just four employees. Ayyappan says, “We struggled a lot at the beginning. Then we became director Blessy’s official media management partner. Through him, we got a lot of clients.”



Sahil has created about 30 Wikipedia articles and Ayyappan is an IMDb contributor who gives online database information related to films, television programmes.Now they are a design agency having 20 employees and creating an innovative website for different clients. They have designed their entire process and products around providing everything a small business needs when they are starting out.

This ensures a quick, easy and hassle-free experience working with them. Ayyappan says, “We give our clients full control of their website without a ridiculous price tag, and our friendly team offers their expertise even after the website is live.”

The world’s fastest supercomputer can now perform 200,000 trillion calculations per second, and several companies and government agencies around the world are competing to build a machine that will have the computer power to simulate networks on the scale of the human brain. This extremely powerful hardware requires extremely powerful software, so existing software code must be continually updated to keep up.

Sunita Chandrasekaran, an assistant professor of computer and information sciences at the University of Delaware, is perfectly suited for this challenge. Under a new grant from the National Science Foundation, she is designing frameworks to adapt code to increasingly powerful systems. She is working with complex patterns known as wavefronts, which are commonly found in scientific codes used in analyzing the flow of neutrons in a nuclear reactor, extracting patterns from biomedical data or predicting atmospheric patterns.

Chandrasekaran is an expert on parallel programming — writing software code that can run simultaneously on many multi-core processors. Parallel programming is an increasingly important discipline within computer science as more and more universities and companies use powerful supercomputers to analyze wide swaths of data, from scientific results to consumer behavior insights and more.

Chandrasekaran is looking at scientific applications to see how they were written, how they have been performing on outdated architectures, what kind of programming models have been used, and what challenges have arisen.

“Most of the time the programming models are created in a broad stroke,” she said. “Because they are generalized to address a large pool of commonly found parallel patterns, often the models miss creating features for some complex parallel patterns, such as wavefronts, that are hidden in some scientific applications.”

A wavefront allows for the analysis of patterns in fewer steps. The question is: How do you get the programming model to do that?

One such example is Minisweep, a miniapp that models scenarios within a nuclear reactor by “sweeping” across a grid with squares that represent points in space and are used to calculate the positions, energies, and flows of neutrons. This parent application to Minisweep is used to reduce the odds of a meltdown and to safeguard engineers who work around the nuclear reactor from radiation exposure. Earlier this year, Chandrasekaran and doctoral student Robert Searles demonstrated how they modified the miniapp to perform 85.06 times faster than code that was not parallelized. This work was recently presented in the premier Platform for Advanced Scientific Computing (PASC) 2018 conference and published by the Association for Computing Machinery (ACM).

“We wondered: Is this pattern specific to Minisweep?,” she said. “Or is it going to exist in other codes? Are there other codes that could benefit if I were to put this type of pattern in a programming model and create an implementation and evaluate it?”

For example, Chandrasekaran discovered that some algorithms in bioinformatics, the study of large sets of biological data, contained similar patterns. She suspects that by adapting the software written for Minisweep, she can make great strides toward improving the code. She will try this with data from Erez Lieberman Aiden, assistant professor of molecular and human genetics at Baylor College of Medicine and assistant professor of computer science at Rice University. Chandrasekaran met Aiden when he visited UD to give a talk titled “Parallel Processing of the Genomes, by the Genomes and for the Genomes.”

Chandrasekaran was inspired by Aiden’s work with DNA sequences. He uses a computing tool to find long-range interactions between any two elements on the same chromosome, in turn showing the genetic basis of diseases. Chandrasekaran suspected that she could utilize existing patterns and update the code, allowing for faster analysis of this important biological data.

“The goal is not to simply create a software tool,” she said. “The goal is to build real-life case studies where what I create will matter in terms of making science easy.”

Directive-based parallel programming models such as OpenACC and OpenMP will be explored to do this.

Chandrasekaran aims to maintain performance and portability as she redesigns algorithms. She will also keep the scientists who use the algorithms in mind.

“You can’t create a programming model by only looking at the application or only looking at the architecture,” she said. “There has to be some balance.”

This project will benefit scientific application developers who are not necessarily computer scientists. “They can concentrate more on the science and less on the software,” said Chandrasekaran. Scientists come to her with data sets and problems that take hours, days, sometimes months to compute, and she figures out how to make them run faster, thus enabling newer science.

Chandrasekaran will analyze data supplied by Aiden at Baylor and physicists at Oak Ridge National Lab. Searles will also work on the project, and Chandrasekaran is looking for an additional graduate student with an aptitude for parallel programming to help with this project.
