  • Python Remains Popular in Programming Language Study 

    Python Remains Popular in Programming Language Study 

    A ranking by analyst firm RedMonk reflects on Python’s continued popularity as a leading enterprise programming language for a number of reasons. According to a recent study by RedMonk, JavaScript also remains widely popular as the web development programming language of choice for a significant number organizations. 

    In many ways, Python’s strong showing in the ranking — drawn from GitHub pull requests and Stack Overflow data — indicates its long-term viability among DevOps developers. 

    “One lack of change that is worth surfacing is Python’s number-two spot,” Stephen O’Grady, a RedMonk co-founder and analyst writes in The RedMonk Programming Language Rankings: January 2021. “Java was extremely hot on Python’s heels – and was, in fact, closer to the number-one ranking than to PHP behind it – but Python’s ability to defend its new high ranking is notable.”

    Python’s prolonged high ranking is notable because of its versatility, Rachel Stephens, a RedMonk analyst who is responsible for the RedMonk Language Rankings’ design, told devopsy.kinsta.cloud. “The breadth of use cases — and associated libraries that support those use cases — means there are a number of possible entry points for developers. The number of toeholds for the language within the enterprise helps its ubiquity,” said Stephens.

    There also remains much discussion about what accounts for Python’s continued popularity beyond the scope of the study. A popular subject in forums, including Reddit, Python is typically described as highly versatile, relatively easy-to-learn and a simple, yet elegant language. While not cited in the RedMonk study, some software engineers and coders — such as this writer — appreciate how Python can make more intuitive sense, and is also less rigid compared to, say, a classic language such as C++. While JavaScript is largely used for web apps and scripts, of course, Python could arguably be the most popular language outside of the sphere of web development, thus accounting for its second-highest ranking in the study.

    As such, “due to the accretive nature of our methodology, movement within the top-ranked languages is an infrequent occurrence,” Stephens said.  

    “[However], Python overtaking and sustaining its ranking over Java was a big deal. That said, we remain strong believers in the future of Java and the Java ecosystem, and we know there is a vast amount of enterprise Java that isn’t captured in the metrics we use,” Stephens said. “We don’t view Python’s ascendence as a zero-sum gain over the use of Java.”

    For JavaScript, “in spite of all of the competition from up-and-coming languages, all the discussion of fragmentation – and even criticisms of JavaScript the language itself – it remains remarkably popular,” O’Grady said.  

    “Simply put, JavaScript remains – its detractors notwithstanding – a force of nature like no other within the industry, and there are no indications in the data that this is likely to change any time soon,” O’Grady added.

    Meanwhile, in the book Hardcore Programming for Mechanical Engineers, published by No Starch Press, JavaScript trails Python in other rankings, while Python is also more popular than JavaScript for other reasons than those described in the RedMonk study. Python, for example, is cited as the ‘The Most Wanted Language,’ based on a Stack Overflow survey. 

    While Python is not the fastest language, as measured  in benchmarks listed in Hardcore Programming for Mechanical Engineers  — Go consistently outperforms it, for example, in execution times — Python’s popularity remains very high overall, according to the book’s author.

    “These results are not surprising; Python is an extremely versatile and productive language,” author Ángel Sola Orbaiceta wrote. “Writing code in Python is a delight, and its standard library is well-equipped: for just about anything you want to do, Python has something ready to help.” 

     

  • NodeSource Gets to the Source of the Node.js Issue

    NodeSource Gets to the Source of the Node.js Issue

    There’s no shortage of variants of Node.js in the world, but NodeSource is making a DevOps-related case for why IT organizations should standardize on its runtime implementation.

    NodeSource released version 2.3 of N|Solid, which adds support for event loop delay notifications that pinpoint precisely where an issue that needs to be addressed has occurred with an application, based on the Node.js variant of JavaScript.

    Pravin Halady, product manager for NodeSource, says N|Solid uniquely provides a runtime implementation of Node.js that provides that capability. Coupled with tools to monitor applications based on N|Solid, additional visualization tools and configurable webhooks-based integration to create alerts that can be shared via collaboration platforms such as Slack, N|Solid is the only Node.js runtime specifically optimized for enterprise IT environments, Halady says.

    He notes one of the thornier issues organizations that embrace Node.js face is that any long-term synchronous activity blocking the event loop can prevent other incoming requests from reaching the server. Before too long, the application hangs or simply crashes. By providing insights into when an event loop delay is occurring in real time, Halady says IT organizations don’t have to waste time trying to reproduce the problem. The result is a much faster time to resolution of Node.js application issues.

    DevOps teams can find themselves dealing with those types of issues at a much higher level of frequency once developers employ Node.js. As adoption of the most widely employed variant of JavaScript increases, IT organizations are managing more applications than ever. In fact, a recent survey published by the Node.js Foundation finds that three out four respondents plan to increase their usage of Node.js over the next 12 months. The primary reasons cited for that additional usage are increased developer productivity (68 percent); improved developer satisfaction (65 percent); reduced development costs (58 percent); and increased application performance (50 percent). Nearly half the respondents (47 percent) working in enterprise IT organizations say they been using Node.js for more than three years. Over half the developers (58 percent), in contrast, report having more than 10 years of experience working with Node.js.

    IT organizations generally have very little visibility into what’s occurring inside Node.js applications, which makes it difficult to apply DevOps processes. In fact, most DevOps processes in place today are wrapped around applications written in more mature languages such as Java. Developers employing JavaScript tend to not be as well-versed in the role programmers ideally play within the context of an integrated set of DevOps processes.

    In the absence of those processes, having the tools needed to debug an application in real time becomes more important to an IT operations teams that needs to inform a developer about the root cause of a specific issue. Otherwise, the developer ends up running one test after another in the hopes of replicating the problem. Unfortunately, the probability of accomplishing that goal inside most organizations is often relatively low. Because of that issue alone, an event loop delay notification made in real time is likely to pay for itself in a matter of hours.
