❕ Uber CEO Dara Khosrowshahi resigns from self-driving truck startup Aurora’s board

Dara Khosrowshahi, CEO of Uber, has resigned from the board of Aurora Innovation, a self-driving truck startup. His decision, effective January 2, 2025, was made to focus on his responsibilities at Uber and to reduce external commitments, with no disagreements reported with Aurora. Khosrowshahi joined Aurora's board after Uber sold its self-driving unit to the company in 2020 as part of a $400 million investment deal.

Shailen Bhatt, COO for AtkinsRéalis, will replace Khosrowshahi on the board. This resignation comes shortly after Aurora's general counsel announced plans to step down. Uber maintains a collaborative relationship with Aurora through its freight platform, although it also partners with other self-driving tech companies.

🔐 Top 10 Features That Make Java Secure 🔐

Java is renowned for its robust security, thanks to these features:

👉 1. JVM (Java Virtual Machine):

Isolates the code execution environment, protecting the host system from malicious code.

👉 2. Security APIs:

Built-in libraries for encryption, authentication, and secure communication (e.g., Java Cryptography Architecture).

👉 3. Security Manager:

Controls application actions at runtime, like file and network access.

👉 4. Void of Pointers:

Eliminates direct access to memory, reducing vulnerability to memory corruption.

👉 5. Memory Management:

Automated garbage collection prevents memory leaks and other misuse.

👉 6. Compile-Time Checking:

Catches errors early, ensuring code integrity before execution.

👉 7. Cryptographic Security:

Advanced encryption and secure data transmission with tools like SSL and digital signatures.

👉 8. Java Sandbox:

Isolates code execution, restricting access to critical system resources.

👉 9. Exception Handling:

Helps prevent unexpected crashes by managing runtime errors effectively.

👉 10. Java Class Loader:

Dynamically loads classes securely, preventing unauthorized code execution.

💡 These features make Java a trusted choice for secure and reliable application development.
