Measuring programming language popularity

Stack Overflow's 2016 Developer Survey Results. According to poll JavaScript is used by 85% of developers. ranks programming languages based on their github contribution rate according to this formula. IEEE Spectrum's 2016 ranking of top programming languages "synthesises 12 metrics from 10 sources to arrive at an overall ranking of language popularity". The various metrics were collected from GitHub, Google Search and Trends, Twitter, Stack Overflow, Reddit, Hacker News, Career Builder,, and IEEE Xplore Digital Library. The interactive ranking app allows adjustment of each metric's weight, and also filtering languages by "type" (Web, Mobile, Enterprise, Embedded).

In 2008, software author Joel Spolsky referred to "she's your wife" in response to complaints that a beta release of Internet Explorer 8 was "buggy" and confusing to end users despite accurately meeting HTML standards, because existing websites had been coded to work around software bugs in older releases. * The customer is always right

Evidence-based scheduling

Evidence-based scheduling is a software estimation approach created by Joel Spolsky, a commentator on software engineering principles. Evidence-based Scheduling is based on at least two core ideas: including all time spent, and using a Monte Carlo completion date prediction method. One of the core ideas of evidence-based scheduling, that adds to the normal estimation practices, is the idea of including all time spent, regardless of relevance. Most people, when estimating, measure the time they actually spend on a project – classic Time Accounting categories such as cited in McConnell's Software Project Survival Guide do not allow for accounting for non-project activities.

Critics have raised concerns about the fate of Quora's data if the site ever goes offline and recommended Stack Overflow as an easily archived alternative. After question details were removed in August 2017, Quora was highly criticized for doing so. According to some users, the removal of question details limited the ability to submit personal questions and other questions requiring question details. According to an official product update announcement, the removal of question details was made to emphasize canonical questions.

The RedMonk Programming Language Rankings, which establishes rankings based on the number of GitHub projects and questions asked on Stack Overflow, ranks Scala 14th. Here, Scala is placed inside a second-tier group of languages–ahead of Go, PowerShell and Haskell, and behind Swift, Objective-C, Typescript and R. However, in its 2018 report, the Rankings noted a drop of Scala's rank for the third time in a row, questioning "how much of the available oxygen for Scala is consumed by Kotlin as the latter continues to rocket up these rankings".

Social media and suicide

Social media and suicide is a relatively new phenomenon, which influences suicide-related behavior. Suicide is a leading cause of death worldwide. According to the World Health Organization, in the year 2020, approximately 1.53 million people will die from suicide. There is increasing evidence that this behavior of using social media affects and changes people's lives, especially in teenagers. Suicide has been identified not only as an individual phenomenon, but it is influenced by social and environmental factors.


TestNG 5
Stackoverflow discussions reflect this controversy. In JUnit 4, the @BeforeClass and @AfterClass methods have to be declared as static. TestNG does not have this constraint. TestNG has provided four additional setup/teardown pairs for the suite, test and groups, i.e. @BeforeSuite, @AfterSuite, @BeforeTest, @AfterTest, @BeforeGroup and @AfterGroup, @BeforeMethod and @AfterMethod. TestNG provide wide range of support to automate application using selenium. This feature is implemented in both tools, however in quite different ways. TestNG has two ways for providing varying parameter values to a test method: by setting the testng.xml, and by defining a @DataProvider method.
