GitHub Analysis reveals the Changing Face of Programming Language Usage

One obvious constant in the technology industry is its rapid pace of change, and the practice of programming offers no exception to this rule. What was once a popular language at the turn of the century might hardly get used for applications today. On the other hard, new programming languages seem to appear on a monthly basis.

Data from the source code repository, GitHub, offers a window on this changing face of software development. Let’s look more closely at their analysis to check the latest trends in programming language usage. Perhaps these insights might be of use in your own team’s development efforts?

393 Different Programming Languages at GitHub – in One Year!

GitHub boasts 4.5 million users who maintain around 10 TB of source code at the repository. Incredibly, those development projects are written in 393 different programming languages. Even more impressive is that data only represents one year of GitHub usage statistics!

Those numbers have only increased since the original July publication of an article by Waren Long at the source{d} blog used as a reference for this post. Another interesting point is their analysis doesn’t even include JavaScript, one of the most widely used languages, because of GitHub users’ propensity to refer to popular libraries, like Node.js or React.js, as a project’s language instead of JavaScript.

Long’s methodology for determining programming language is quite detailed, so refer to the link in the previous paragraph for additional insights, if interested. 

The Current Most Popular Programming Languages on GitHub

There are few surprises listed among the most popular languages currently in use at GitHub. Python and Java rank at the top of the list, with a popularity percentage of 16 and 15.3 respectively. That doesn’t necessarily mean both languages have more lines of source code stored in the repository. That honor lies with PHP, even though it only ranks at #5 on the popularity scale.

Other languages in the top 10 include the venerable, like C, C++, and C#, along with relative upstarts like Ruby, Objective-C, and Go. Apple’s newer programming language for iOS applications, Swift, rounds out the top 10. A related analysis adding in Google search queries to the GitHub data notes that Go is currently the “hottest” programming language.

Moving from One Language to Another

The original source{d} blog article also looked what languages programmers are transitioning into over time. This is useful information for both individual developers as well as software development shops. For example, many Visual Basic developers eventually transition into C#, which isn’t surprising for programmers working primarily on the Microsoft technology stack.

PHP developers, on the other hand, tend to move into Java, Python, or even C#. Python’s current popularity is confirmed by the fact that 24 percent of programmers working in the five other most popular languages — Java, C, C++, PHP, and Ruby – eventually work with Python. The “walled garden” nature of Apple platforms is revealed by the high percentage of programmers switching between Swift and Objective-C for project work.

Ultimately, anyone working as a programmer or a manager of software development needs to dive into the source{d} analysis of GitHub’s data. It’s truly fascinating.

Software Architects need these Four Essential Skills

Of course, strong technical ability is a requirement for anyone employed as a software architect. This role is almost always filled with someone who forged their skills working at least a few years as an application engineer. What separates the best architects from those merely holding the job title are the other intangibles necessary to thrive in today’s business world.

O’Reilly Media recently looked at four essential abilities a software architect needs to truly be successful in this era of Agile and DevOps. Let’s take a closer look at these skills to see if adding them to your toolbox makes you better at the practice of software development. Good luck!

Technical and Business Leadership

A good software architect knows how to lead the developers on his team, while also working closely with business stakeholders and project managers to ensure the project requirements are clearly defined with sufficient progress being achieved. Mark Richards, an experienced software architect and author, commented on the importance of this trait.

“It’s being a technical as well as business domain go-to person, it’s really to help clear roadblocks to the team so they can actually move forward. Being a leader as an architect means providing technical help and guidance, it means to help the team make decisions and form those decisions and validate them, and also to provide motivation to the team and support whether it be technical or non-technical support,” said Richards.

The Ability to Negotiate

Software architects also need to be able to negotiate at times to ensure a technology project proceeds in a smooth fashion. This skill comes into play when first determining the technology stack and basic architecture for an application. Sometimes, stakeholders may want a feature beyond the scope of the project or its budget. Similar negotiations happen with project managers and even the development staff, ensuring buy-in before the actual work commences.

Strong Decision-making is a Must

While the product owner or project manager typically rank higher in the hierarchy of most technology projects, a software architect still needs to possess strong decision-making skills. This especially comes into play regarding the technology stack used on a project, i.e. programming language, database, virtualization platform, etc. A strong-minded and confident approach definitely helps to formulate a robust architecture for a software application.

Collaboration is Vital in Today’s Technology World

It stands to reason any software architect working at a company with a DevOps organizational structure knows how to collaborate with their coworkers. Many enterprises also use architectural teams to define system architectures as a group. In this latter case, being able to share ideas and concepts with other like-minded professionals – in an ego-free fashion – helps ensure the best possible applications are built for the organization. Richards feels a mediator role helps when architectures are defined using a team instead of an individual architect.

In any case, it is obvious the best software architects possess a variety of skills that go beyond writing great code. Consider developing these abilities in your own work to take your software development career to a higher level.

Barman and repmgr – Essential Tools for PostgreSQL

If your company’s software engineers are veterans with PostgreSQL, chances are pretty good they are also familiar with the utilities, Barman and repmgr. Barman handles the management of the backup and recovery process for a Postgres instance. While repmgr, as hinted at by its name, performs a similar role with replication – in fact repmgr also offers a measure of integration with Barman.

Let’s take a closer look at both tools to see if they make sense as part of your PostgreSQL implementation. If your team is considering Postgres as a cheaper alternative to Oracle, perhaps this additional information helps make your decision easier. Good luck!

Barman – the PostgreSQL Choice for Disaster Recovery

Developed by the well-known purveyor of Postgres support, training, and development, 2ndQuadrant, Barman is a worthy open source option for organizations needing a tool to handle backups and restores for PostgreSQL. It also plays an important role in any company’s disaster recovery process. Barman helps ensure databases are back online as quickly as possible – a vital factor in achieving business continuity.

In fact, Barman focuses its functionality on disaster recovery scenarios. It supports the remote and hot backups of multiple database servers, while helping DBAs or other network personnel get everything up and running again. The tool also provides remote management capabilities for multiple servers, including ssh support.

Other features include the local storage of metadata, PITR (Point-In-Time-Recovery), file compression, retention policies, incremental backups, tar integration, and more. In short, Barman is a fully functional backup and recovery solution for Postgres. Since it is written in Python, companies with developers skilled in that language can make modifications as needed.

Version 2.1 of Barman was released earlier this year. 2ndQuadrant also provides documentation as well as commercial support and consulting options. As an open source software product, a robust online community is available for advice on usage. Any company using PostgreSQL needs to explore Barman as an option for database backup and disaster recovery.

Manage PostgreSQL Replication with repmgr

Another open source Postgres utility developed by 2ndQuadrant, repmgr handles database replication across multiple PostgreSQL servers. The latest version of repmgr – 3.3.1 – was released in March of 2017, supporting Postgres versions 9.3 and later. It leverages streaming replication and the PostgreSQL 9 Hot Standby feature to ensure superior performance in high scalability and availability environments as well as ease of administration.

One of the unsurprising features of repmgr, considering the developer, is its seamless integration with Barman. You are able to make clones from a Barman archive, instead of accessing a live server. This helps prevent a performance hit on a production server.  If live streaming replication gets interrupted, an archive can be easily used in a pinch.

As with Barman, 2ndQuadrant also provides commercial-level support and consulting options with repmgr. When used together, both tools make it easier for companies to build an industry-leading relational database solution at a fraction of the cost of going with Oracle. It is yet another example of the benefits of open source software.
