AWS Unveils EMR Studio IDE for Data Scientists, Highlights Linux Kernel Security

EMR Studio IDE

AWS announced the EMR Studio integrated development environment, designed to let data scientists and engineers quickly develop, visualize, and debug applications written in R, Python, Scala, and PySpark. The managed IDE offers fully hosted Jupyter notebooks, Spark UI access, YARN timeline services, and supports custom kernels and libraries via orchestration services. Users can run the IDE on existing EMR clusters or launch new clusters using CloudFormation templates or the AWS CLI.

Linux Kernel Contribution Ban

Linux kernel maintainer Greg Kroah‑Hartman has prohibited the University of Minnesota from contributing to the kernel after researchers were found submitting malicious code and intentionally introducing security‑critical patches as part of a study. All past submissions from @umn.edu have been reverted, and the university’s computer science department has issued a statement pausing the controversial research.

Chrome Adopts Hardware Stack Protection

Google Chrome now incorporates a hardware‑enforced stack protection scheme co‑developed by Intel and Microsoft, leveraging Intel Control‑Flow Enforcement Technology (CET). CET maintains a shadow stack of valid return addresses and raises exceptions on violations, mitigating ROP and JOP attacks. The feature requires 11th‑gen Intel or AMD Zen 3 CPUs, Windows 10 2004+, and is already present in Chrome 90, with plans to roll out to other Chromium‑based browsers.
