David Eads is a news applications developer at ProPublica Illinois, where he combines journalism with software development. Ever since he built the website for his high school newspaper in 1996, Eads knew he wanted to work at the intersection of media and technology. He moved to Chicago for college in 1999, studying physics at North Park University. During school he helped found the Invisible Institute, where he also maintained a blog about Chicago public housing called The View From The Ground. He later helped create FreeGeek Chicago, a community-based computer recycling organization and the Supreme Chi-Town Coding Crew, a weekly workshop to teach data journalism. He’s also worked on visual journalism teams at the Chicago Tribune and, most recently, at NPR Visuals.
The point in this case is that there was no reason to switch from a language that we commonly use for its flexibility and broad support when in this case, it's more than fast enough. The costs of using something faster (but less supported in my workplace) are higher than whatever benefit we'd get from using something marginally faster.
