When it comes to developers' work habits and the languages they use, C# programmers tend to start and stop work earlier than C programmers, who stay up later. But for programming outside of the common 9-to-5 workday, Haskell gets the nod.
In analysis of programming traffic on the Stack Overflow online community over for four weeks last August, Stack Overflow Insights data scientist David Robinson, found that traffic spikes during the workdayâunsurprising since the site is used by programmers to help them do their jobs. "You can even see a dip at 12 p.m. when developers eat lunch," he noted.
Technologies used outside the workday include web frameworks like Firebase, Meteor, and Express, as well as graphics libraries like OpenGL and Unity, but Haskell dominates the category, with half of its visits coming after hours. The workday, meanwhile, is dominated by many Microsoft technologies, such as SQL Server, Excel, VBA, and Internet Explorer, along with technologies Subversion and Oracle, which are frequently used at enterprise software companies, Robinson found. "We can see that of the most used programming technologies on Stack Overflow (more than 100,000 visits a day), C#, SQL, SQL Server, and Excel stand out as being disproportionately used from 9 to 5, while Android, iOS, Swift, Node.JS, C++, and C are more visited outside of work hours."
Robinson also found that cities in western Europe, such as London, Paris, Madrid, and Amsterdam, kept the strictest 9-to-5 hours. On the other hand, developers in eastern Asian cities like Quezon City, Tokyo, and Seoul, or eastern European cities like Moscow and Kiev were most likely to visit outside local working hours.
