Quality Outreach Heads-up - Separate Metaspace and GC Printing
- The OpenJDK Quality Group is promoting testing of FOSS projects with OpenJDK builds to enhance release quality.
- Starting with JDK 25, Metaspace and GC logs in HotSpot JVM will be separately tagged to avoid confusion.
- Metaspace-related log messages will now use the existing metaspace tag, distinct from GC logs.
- User-facing changes in jcmd are also made to reflect that Metaspace is not part of the GC Heap.

LD_PRELOAD explained
- LD_PRELOAD is an environment variable on Unix-like operating systems that allows users to specify a shared library to be loaded before others when a program is executed.
- This functionality is provided by the system dynamic linker and works only for dynamically linked executables.
- The dynamic linker is a program that handles the execution of all dynamically loaded programs on the system.
- LD_PRELOAD adds a list of shared libraries to be loaded after the program image but before its shared object dependencies.
- Examples of using LD_PRELOAD include Zlibc for decompression and overriding functions like malloc, read, and write.
- LD_PRELOAD can be used for testing, hot-fixes, observability, alternative implementations, and injecting custom code.
- Other ways to preload a library on Linux include using LD_PRELOAD environment variable, --preload option when invoking the dynamic linker, and /etc/ld.so.preload file.
- Security implications of LD_PRELOAD need to be considered, as it can override system calls and potentially introduce security vulnerabilities.
- Mitigations against security risks include limited preloading for secure-execution mode binaries on Linux.
- Alternative solutions like eBPF exist, offering more restrictions and fewer security concerns compared to LD_PRELOAD.

Forget Code Exist: Is ‘Vibe Coding’ The Future?
- Vibe coding is a new approach in software development where developers rely on AI assistance and focus on prompt engineering rather than deep understanding of code.
- Developers using vibe coding often rely on AI-generated code by providing detailed descriptions of requirements and feeding back errors for fixes.
- While vibe coding accelerates project initiation, the output quality and reliability are dependent on the clarity and detail of prompts, with risks of errors, bugs, and security vulnerabilities.
- Thorough code review and testing remain essential in vibe coding to validate AI output, optimize performance, and ensure adherence to best practices and security standards.

- The core message of the piece is captured in the phrase “Pride in the shadows, still we shine”, acknowledging queer Nigerians who continue to love, resist, and shine even in the face of oppression.
- Created using HTML, CSS, and vanilla JavaScript, this project challenged the creator to think like an artist and storyteller, aiming to convey a personal narrative of celebrating pride in private moments and finding joy in color amidst darkness.

Computing the Euler-Mascheroni Constant
- The Euler-Mascheroni constant can be computed by evaluating an equation with a large n, but convergence is slow and rounding errors accumulate.
- A more efficient approach involves adding an extra factor of ½ in the log term, which converges faster to the Euler-Mascheroni constant.
- Comparing the two methods, the error in the first method with n = 4000 is similar to the error in the second method with n = 16.
- Software like y-cruncher has been used to set world records for computing constants like π and the Euler-Mascheroni Constant, which is particularly challenging to compute.
