Microsoft this week announced the commercial availability of Azure Database services for both MySQL and PostgreSQL.

The two open source database management systems reached “general availability” status on Azure after having been previews on Azure Database infrastructure since last year. They are currently available in “22 regions worldwide,” but Microsoft is planning to expand availability to all Azure regions “in the coming months.”

Azure Database on MySQL and Azure Database on PostgreSQL were both described as “community editions” by Sunil Kamath of the Azure Database engineering team in a Microsoft video. Both meet various compliance standards, including HIPAA. Microsoft also is promising compliance with the General Data Protection Regulation (GDPR) when it comes into effect on May 25.

The use of MySQL and PostgreSQL on Azure datacenter infrastructure adds built-in scalability and high availability, plus a 99.99 percent service-level agreement uptime assurance from Microsoft. Both database management systems can scale to 32 “vCores,” according to Microsoft’s announcement.

Organizations can use a toggle switch in the Azure Portal to connect the database management systems to Azure services, according to a demo by Kamath. PowerShell is built into the Azure Portal for management tasks. It’s possible to set backup for 35 days before restoring data, and it’s also possible to set up backup in a different Azure region to get data redundancy protections, according to Kamath.

The announcement claimed that existing tools, such as mysqldump and pg_dump (for PostgreSQL), can be used to migrate these databases to Azure datacenters. There’s also a “limited preview” available to use the Azure Database Migration Service to move MySQL workloads to Azure infrastructure. Microsoft is promising to add PostgreSQL migration support to that tool, as well. The Azure Database Migration Service is still at the preview stage.

Microsoft’s next planned open source addition to Azure Database will be the MariaDB database management system, a MySQL variant. It’ll be arriving on Azure in the “coming few months,” the announcement indicated. It had been available as a preview since November, which is when Microsoft joined the MariaDB Foundation.

Nowadays, if you are a newbie who knows little or nothing about the world of programming, there are dozens of alternatives available to learn to program from scratch. It is a huge world. However, if we enter the most specific niche of back-end web development, the main alternatives are PHP and Python.

PHP Technology Overview

Let’s talk about  PHP first. PHP was created by Rasmus Lerdorf to specifically build dynamic web pages.  PHP came out in 1994 and was a radical revolution in its time. Important pages such as Facebook, Tumblr, Yahoo and Wikipedia were made using PHP, and 83% of websites around the world use PHP.

Python Technology Overview

Python is older than PHP and was created by Guido van Rossum in 1989, as a successor of the ABC language. However, it only became popular among programmers when it incorporated full Unicode support in the 2000s. It is a multi-paradigm language for thousands of uses, from Big Data, Artificial Intelligence and scientific research, to web, mobile and desktop development. Despite being used by giants such as YouTube, Reddit and Spotify, less than 1% of the websites are made in Python. Nonetheless, it is quite popular in other work fields.

PHP Vs Python Technology

PHP and Python are multi-paradigm languages that support imperative programming, procedural programming, object-oriented programming, and even functional programming.

In terms of web programming, PHP has greater advantages, despite its shortcomings. It has dozens of frameworks such as Symphony, Laravel, CodeIgniter, Banshee, Zend, etc., and is quite adaptable, compatible with almost all existing hostings and the most popular CMS on the planet, like WordPress, is built in PHP. Two of the main open source e-commerce platforms, Magento and WooCommerce, are also made in PHP.

Python offers a more limited offer, being compatible with few hostings (which incidentally tend to be more expensive than those compatible with PHP projects). It has a smaller but quite varied offer of frameworks for web development, with  Django and Flask being used the most. Python also offers several CMSs based on Django that have a modest number of followers.

Both languages are excellent options when programming web pages. Unquestionably, the most appropriate for a noob programmer is Python, because their interpreter forces you to write and correctly devise your code to execute it correctly, unlike the messy and often poorly written PHP code.

For its part, PHP is harder to learn and less welcoming for a new user. Another advantage of Python is that it is very tolerant of syntax errors and its interpreter doesn´t usually break code for minor errors. It is very easy to learn. That’s why it’s strange that Python isn´t in the majority of schools of computer science schools in India, unlike many countries of the world. Interestingly, most Indian developers do know how to use PHP.

PHP Vs Python Technical Aspects

Technically speaking, executing a PHP code is slower than executing a code in Python, and if you use a framework like Laravel it doesn´t generate an intermediate bytecode during execution. Also, you must write more lines of code to do the same task as in Python.

PHP is less secure than its rival and requires additional security software to develop an app, unlike Python, which by itself is quite safe without add-ons.

Among other advantages, Python programmers are better paid and more demanded, due to the scarce offer available to Indian programmers in Python. In fact, recently one of the top app development companies Indiafirm  was forced to pay thrice of billing rate to American freelance Python programmers to build the platform of a US bank, because they didn´t have enough own programmers for the task. Outsourcing companies such as Infosys, TCS or Wipro are very reluctant to use Python, preferring to use Java, C ++, PHP or .NET.

On the other hand, a PHP developer must face greater labor competition and worse salaries because the supply of labor is much greater. Both languages have an excellent community ready to help you in everything you need, and good and extensive documentation.

Conclusion

In summary, when analyzing both the languages, if you want to learn to program in all existing development environments today, without limitations, your best option is Python. Especially if you are thinking about specializing in Artificial Intelligence or scientific research. It’s true that it´s more difficult to find good hostings and quality supplements for web development in Python, but the effort is worth it.

Apple’s event on Tuesday is looking be to slightly unusual.

It will not be in California. It will not be livestreamed.

And there will be no new iPhone — unless the analysts and internet rumor mongers are wrong.

Tuesday’s event will focus instead on education and is even being held at Chicago’s Lane Tech College Prep High School.

The invitation read “Let’s take a field trip.”

Ars Technica is reporting the school has previously taken part in Apple’s Learn to Code program.

Apple is not saying anything official yet about the event, but Bloomberg is reporting that Apple will be offering both software and hardware launches that are educationally focused.

According to the Ars Technica report, this includes software that teachers can use to assign homework, monitor tests and conduct other classroom activities.

Newer, cheaper iPad?

On the hardware front, Apple is expected to launch a newer, cheaper iPad.

Bloomberg is reporting the Apple’s event may be part of an move to regain lost ground in the classroom.

Apple share of the kindergarten to Grade 12 market is only 17 percent, which is slightly behind Microsoft and massively behind Android tablets and Chromebooks, which command 60 per cent market share.

Apple’s entry level iPad price is $329.

Chromebooks can be had for half that price.

The new iPad is expected to work with the Apple pencil, although there are rumors that Apple will drop the price on that too.

The Pencil is a wireless stylus that currently retails for $99 (Dh367).

There is also the possibility of an MacBook Air update, but details are scarce on whether this is an update or a redesign.

Did we say ‘No iPhone’?

Well, most analysts are saying this is only an outside possibility — but we might see them release an iPhone SE2.

The SE is the smallest of the iPhone line, which comes with a 4-inch screen.

Oracle announced the general availability of Java SE 10 (JDK 10) this week. This release, which comes barely six months after the release of Java SE 9, is the first in the new rapid release cadence Oracle announced late last year.

The new release schedule, which the company is calling an “innovation cycle,” calls for a feature release every six months, update releases every quarter, and a long-term support (LTS) release every three years. Java 10 is a feature release that obsoletes Java 9. The next LTS release will be Java 11, expected in September. The next LTS version after that will be Java 17, scheduled for release in September 2021.

“Oracle is committed to rapidly evolving and delivering new innovations in the Java platform – this being the first in our newly adopted release cycle and licensing model,” said Georges Saab, vice president of Software Development in Oracle’s Java Platform Group. “We’re especially proud of the simplicity of this release, which introduces useful new features, removes unnecessary elements, and is easy for developers to use.”

The six-month feature release cadence is meant to reduce the latency between major releases, explained is Sharat Chander, director of Oracle’s Java SE Product Management group, said in a blog post.

“This release model takes inspiration from the release models used by other platforms and by various operating-system distributions addressing the modern application development landscape,” Chander wrote. “The pace of innovation is happening at an ever-increasing rate and this new release model will allow developers to leverage new features in production as soon as possible. Modern application development expects simple open licensing and a predictable time-based cadence, and the new release model delivers on both.”

This release comes with 12 new enhancements defined through the JDK Enhancement Proposals (JEP) process, which is Oracle’s version of the Java Specification Request (JSR) process of the JCP, including:
Local-Variable Type Inference: Enhances the Java Language to extend type inference to declarations of local variables with initializers. It introduces var to Java, something that is common in other languages.
Consolidate the JDK Forest into a Single Repository: Combine the numerous repositories of the JDK forest into a single repository to simplify and streamline development.
Garbage Collector Interface: Improves the source code isolation of different garbage collectors by introducing a clean garbage collector (GC) interface.
Parallel Full GC for G1: Improves G1 worst-case latencies by making the full GC parallel.
Application Data-Class Sharing: To improve startup and footprint, this JEP extends the existing Class-Data Sharing (“CDS”) feature to allow application classes to be placed in the shared archive.
Thread-Local Handshakes: Introduce a way to execute a callback on threads without performing a global VM safepoint. Makes it both possible and cheap to stop individual threads and not just all threads or none.
Remove the Native-Header Generator Tool: Remove the javah tool from the JDK since it has been superseded by superior functionality in javac.
Additional Unicode Language-Tag Extensions: Enhances java.util.Locale and related APIs to implement additional Unicode extensions of BCP 47 language tags.
Heap Allocation on Alternative Memory Devices: Enables the HotSpot VM to allocate the Java object heap on an alternative memory device, such as an NV-DIMM, specified by the user.
Experimental Java-Based JIT Compiler: Enables the Java-based JIT compiler, Graal, to be used as an experimental JIT compiler on the Linux/x64 platform.
Root Certificates: Provides a default set of root Certification Authority (CA) certificates in the JDK.
Time-Based Release Versioning: Revises the version-string scheme of the Java SE Platform and the JDK, and related versioning information, for present and future time-based release models.

MySQL is gearing up for its 8th version, expected to be released in 2018. A full 28 months have passed since the first general release for MySQL 5.7.9, and there have already been five release candidates for MySQL 8, ranging from 8.0.0 to 8.0.4. These release candidates are only intended for development purposes and should not be used in production systems — they are not supported for upgrades, and users may experience data format incompatibility between release candidates and general availability versions.

The first thing a user of MySQL might notice is the jump in version numbering. This is because version 6 was dropped and version 7 is reserved for the enterprise product line. Window functions is one of the most interesting features of MySQL 8. Already present in other database engines, window functions can perform aggregations on a group of query rows, producing a result for each row. Similar to window functions, Recursive Common Table Expressions lets users perform subqueries referring to its own name without the use of cursors. This presentation explains the subject in detail.

The default character set support is also changing from latin1 to utf8mb4. utf8mb4 uses up to four bytes per character and is the character set of preference for most use cases, as it supports extended collations like utf8mb4_ja_0900_as_cs for Japanese and also, emojis. On storage side, the default storage engine will be InnoDB.

Invisible indexes allow DBAs to exclude an index from the query optimiser in order to test if this index is improving performance or not, and stage indexes before actually enabling them for users. JSON support has improved significantly, with the addition of the JSON_EXTRACT() function that can extract data from a json field based on a path query argument. JSON_ARRAYAGG() and JSON_OBJECTAGG() aggregation functions can be used to combine data into JSON arrays and objects respectively.

Finally, MySQL 8 provides flexible roles support, with create, drop and grant to roles functionality and even granting roles to roles. Limiting roles per session and specifying hosts that can use roles are all available with MySQL 8. DBAs can also get a GraphML visualisation of the roles by calling the ROLES_GRAPHML() function.

MySQL 8 was scheduled to be released in October 2017, and while 8.0.4RC was released on 23rd January 23 2018, there appears to be at least another two release candidates scheduled before the GA version rolls out.

Businesses and organizations today are always on the lookout for new tech that uplifts excellence, but is cost-effective. Software or apps that are Java-based help companies realize these values.

Java is an open source, platform independent and most preferable technology, as well as global standard, for implementing every kind of app, including web-based, client-server, cloud, mobile and enterprise. Organizations are adopting Java app development to drive innovation, lower costs and boost services.

The rise of the internet of things
The internet of things and the rise of M2M ecosystems are in the process of converging with big data and cloud computing, which requires a seamless platform that runs from the device to the data center with Java. Oracle offers a secure, comprehensive, integrated platform for the whole IoT architecture across all vertical markets, with key features that include:

Faster market time
Real-time response capabilities for millions of devices
IT systems integration
End-to-end security
Worldwide, coordinated partner ecosystem
End-to-end compatibility, as well as lifecycle management
Java, the go-to language for the internet of things
Java remains the number one choice among developers and is the leading development platform in the world, with millions of Java developers worldwide. It’s the go-to language for IoT apps. According to Oracle, one of the biggest perks of Java is the robustness of the app code. While C makes use of explicit pointers to reference memory, all object references in Java are implicit pointers that could not be manipulated by app code. This rules out potential concerns automatically, such as memory access violations, which could inevitably cause an app to stop suddenly.

Developers choose Java for IoT gateways
A recent survey suggests that Java is gaining strength for developing embedded IoT apps. Java programmers are often using the programming language for IoT gateways. The data makes clear that a huge percentage of Java developers are working on IoT or planning to work on or partner for IoT efforts.

The Java programming software was designed to be easy to use and thus easy to write, compile, debug and learn compared to other programming languages. This helps in creating modular programs, as well as reusable code. One of the most significant benefits of the Java language is its ability to move easily from computer system to computer system.

Top reasons to use Java in embedded apps
It makes use of the extensive library of standard APIs. Java SE7 has almost 4,000 standard APIs, which can be used for anything from networking to concurrency. What this means is that one already has almost everything needed written already and there is no need for minimal rewrites to make the applications work.
To be platform independent. Java enables writing one and running apps on any other application. This means that one could use it on desktops and embedded systems, with no worries on platforms or devices where it’s going to run. Furthermore, even if porting the app to a later Java version, all it takes is to recompile the code.
It avoids segmentation fault. Java is one very robust app programming language. Unlike C or C++, Java uses implicit pointers for all object references, which helps avoid buffer overruns, violations of memory access and other possible problems that could cause the app to hang or stop. Java, in effect, can help avoid a whole lot of headaches.
The language is low maintenance. Java can be run with only 64 MB of RAM on a machine that runs Windows XP. Embedded machines have better specifications, meaning that Java applications could run on these systems efficiently. As a matter of fact, the Java ME Embedded from Oracle runs on systems with just 130 KB of RAM and 350 KB of ROM.
To forget the small things. The Java virtual machine can deal automatically with memory management, so there is no need to keep track of object references or reallocate memory manually. Ultimately, one could avoid memory leaks. The Java virtual machine can also handle concurrency support.
To deploy applications anywhere, easily. Embedded systems are not the same as desktop computers as typically they do not have screens or displays. Java enables using a desktop or laptop computer for developing the app and then deploying it somewhere else. One could compile the code anywhere, with no need to write complex cross-compilation codes. Furthermore, one could use remote debugging to work out errors in the deployed applications.
To become more productive with Java. Working with Java allows one to have the best tools in the market. One can use Eclipse or NetBeans to make writing code not just easier, but faster as well. One could have code automatically completed and the syntax could be checked instinctively even before one finishes typing it out. With no need to rely on text editors , one could cut development time drastically.
Java is everywhere. Java can be used anywhere, and it is everywhere — from device to data center. The embedded system would be networked to other embedded systems and a data center where the data that it gathers can be analyzed, compiled and then searched. The great news is that enterprise-level apps are also written using the Java platform.
Why Java is needed for IoT
Java is a platform that offers network portability. It’s also one of the few programming languages that developers can easily learn. These two aspects merge to make Java the perfect program to help devices connect. Almost all devices, from personal computers to mobile phones, use Java. It’s an integral part of the internet world, making it a great choice for the internet of things. It offers every device the best functionality level and gives it a high security level, as well as a good amount of scalability in the industry.

Java developers and programmers are working on developing innovative IoT applications, which help in achieving the goal of a connected world. Java programmers jobs are plentiful, thus there is always room for more talent to join.

Java is still one of the most popular coding languages for developers, but drops in the job market and slow growth mean it may need to evolve for use cases like machine learning and IoT.

Java may be ready for a new beginning after spending the past two decades as a general purpose programming language mainstay. While it remains one of the most popular programming languages in use today, its demand in the enterprise has diminished in recent years, and other languages are beginning to outpace it in terms of growth.

Java decreased in popularity by about 6,000 job postings going into 2018 compared to going into 2017, according to an analysis from Coding Dojo. In Q1 2018, it remained the no. 2 most popular programming language behind JavaScript, according to RedMonk, but Swift and Kotlin were growing the most rapidly.

“Java is at a bit of a crossroads,” said Forrester vice president and principal analyst Jeffrey Hammond. While it’s still one of the five most popular programming languages used by developers, a push toward microservice-based architectures are making alternatives like Node.js or Go appealing, he added.

SEE: Job description: Java developer (Tech Pro Research)

Java is used most often in cloud computing, data science work, web development, and app development, said Karen Panetta, IEEE fellow and dean of graduate engineering at Tufts University.

“I still see it evolving, and very popular,” Panetta said. While languages such as Python are growing as well, Java is adapting to the increasing number of deep learning and machine learning workloads. “There’s becoming a lot of libraries out there that are compatible for deep learning,” Panetta said. “I think the fact that we keep talking about cloud computing and all of those things, that Java is still going to be the dominant player.”

Java also has built in more security options than Python, so it’s a good option for Internet of Things (IoT) applications, Panetta said.

Java has a foothold everywhere, and large user groups and libraries already written, making it a natural pathway for machine learning, Panetta said. “It’s evolving to meet the needs,” she added. “It’s always been valuable because of its cross-platform functionality. But now it’s becoming even more valuable because it’s also built up this repository of really solid usable free software that’s out there. So you can jump into any big, giant project you want because most of it’s already written for you. You just put the pieces together.”

Indeed, if you search GitHub for “machine learning,” you’ll find 2,915 Java repository results.

The future of Java
Java should be one of the first three languages new developers learn, Hammond said. The others might include JavaScript, C, C#, or even Racket, which is what MIT uses in its intro to computer science courses, he added.

“Java is one of the best examples of a classic object-oriented static language,” Hammond said. “Knowing both the strengths and weaknesses of a static languages versus a dynamic language like JavaScript is very useful for aspiring developers.”

And despite drops in job postings, Java is also still one of the top languages businesses look for when hiring developers, Panetta said. “Businesses are recognizing they need to move into deep learning and artificial intelligence, and Java is the key language they are using right now to do that,” Panetta said. Java was the language that saw the biggest rise in demand from businesses in the UK and Ireland during the second half of 2017, according to Stack Overflow.
In the future, Java will likely continue to be used as the basis for infrastructure and microservice development, Hammond said. It will also likely move to the cloud, along with most workloads.

“I think you’ll continue to see new developers learn Java, but I think that it will also have to really continue to focus on coexistence with other programming languages and technologies as they continue to grow as well,” Hammond said. “The most important thing is that Java is changing, and it’s starting to pick up innovation speed again.”
