After A Few Short Years, VS Code Passes Rational Developer for i
It has finally happened: Visual Studio Code has passed Rational Developer for i in usage, according to the 2026 version of Fortra’s IBM i Marketplace Survey. The survey also shows lower adoption of greenscreen ADTS and increased use of DevOps tools, demonstrating some positive trends in IBM i application development.
It’s been barely two years since Fortra started asking IBM i customers about their use of Visual Studio Code, the free, Web-based integrated development environment (IDE) originally developed by Microsoft and set free as an open source project in November 2015.

IT Spending Forecast Keeps Going Up And Up, But It Won’t Go Away
Every time we turn around, the hyperscalers, cloud builders, and model builders slap down a couple 10 billion dollars in incremental spending on AI systems to fulfill their GenAI dreams, and all the market researchers have to pull out their models and have another whack at trying to case what will be spent in the coming years. This also gives them another chance to tweak their estimates for spending in the prior year, if it needs updating.
The forecasting wizards at Gartner have just released a revised spending breakdown for 2025 and – surprise, surprise! – an upwardly revised forecast …
