Stop Polluting Your Domain with Static Factories: Clean Validation with Java 25 Flexible Constructor Bodies

Stop Polluting Your Domain with Static Factories: Clean Validation with Java 25 Flexible Constructor Bodies For years, Java forced us to write bloated static factory methods just to validate arguments…

  • Eliminate static factories for argument validation in Java classes.
  • Validate arguments directly within constructor prologue before calling super().
  • Use Java 25's compiler enforced pro-construction context for clean, idiomatic object hierarchies.

Make it right, maintainable, fast, and pretty (in that order)

I don't consider myself a vibe coder. I like reading the code. More specifically, I want to architect a feature, debate about its merits, iterate on its implementation, and finally review the code at…

  • Correctness is the top priority in coding
  • Maintainability ensures long-term benefits

ZcopyReaper: A Local Privilege Escalation in the Linux Kernel RDS Path

ZcopyReaper: A Local Privilege Escalation in the Linux Kernel RDS Path Kernel local privilege escalation flaws rarely make headlines, because they require an attacker to already have a foothold.

  • CVE-2026-43502 is critical RDS zerocopy send path vulnerability in Linux kernel
  • Local attacker gains root privileges through memory corruption flaw
  • Users should apply kernel update and disable unused RDS kernel module

Diagnosing and Fixing Flaky Microservice Tests

[Why microservice tests become flaky — the root causes] [How to reproduce and isolate flaky behavior reliably] [Fix patterns that actually stop flakiness: deterministic data, timeouts, mocks, and…

  • Flaky microservice tests cause developer time loss and CI pipeline mistrust
  • Root causes include concurrency issues, non-deterministic environments, and external dependencies
