Now make that more personal: How much do you or your employer depend on open source? According to the 2024 Open Source Security and Risk Anal...

By Simon Ritter Despite advances in cloud computing, mobile development, and AI, the day-to-day business of enterprises around the world still runs on three programming languages that made their debut in the 1990s. In nearly every ranking system, JavaScript, Python, and Java appear near the top of the most popular languages. In GitHub’s yearly State of the Octoverse report, the programming trifecta has held three of the top four spots every year since 2014.
