I work directly on live Linux server incidents — from compromised systems and malware infections to high CPU usage, service crashes, and production outages. My focus is fast diagnosis, controlled recovery, and long-term hardening.

curl 8.21.0 shipped on June 24, 2026 with patches for 18 vulnerabilities — the most CVEs ever fixed in a single curl release, bringing the project's lifetime total to 206. One of the flaws had been sitting in the code for over 25 years. For a tool

The Redis Problem Nobody Talks About Until It Bites When the conversation shifts to "we need a cache," most teams reach for Redis. It's a solid tool, well-featured, and everyone knows it. You hand off the connection string and move on. Then, months in, something
Kubernetes
Centralized logging on Kubernetes has a way of turning into your most expensive observability line item. The usual culprit is the index. Elasticsearch-style stacks index every word of every log line, and that full-text index can balloon to roughly the size of the raw data it's
DevOps
The Problem: Complex Queries Outgrow GET and POST In REST, the HTTP method tells the server your intent. GET fetches, POST creates, PUT updates. This works fine until you need to send a complex read-only query with a structured body. GET + Query Parameters Filtering resources with query parameters is
Linux
The best distro for developers isn't the one topping DistroWatch. It's the one that matches what you build and where it deploys. Pick wrong and you'll spend the first week of every project fighting your own environment instead of writing code — and you'
Cloud Security
Why Standards Exist, and Why You Run Several at Once Cloud security standards translate legal, contractual, and industry expectations into auditable controls for identity, data protection, logging, and resilience. They give security, legal, and engineering teams a shared language for controls, evidence, and assurance. The thing nobody tells you starting
Linux
The "Address Already in Use" Problem You restart a service, get Address already in use, and now something's squatting on port 8080 that you need to find and kill—without rebooting the whole machine. This happens constantly. The fix is straightforward once you know the commands,
DevOps
The Glue Code Problem If you run Terraform and Ansible together, you know the tax: custom scripts, CLI wrappers, and brittle glue code whose only job is keeping the two tools in sync. It breaks during upgrades, it's a pain to maintain, and it creates governance gaps because

The Feature That Sat Unused for a Decade Worktrees are the latest hotness in git. Which is funny, because they've been around since 2015. They're useful, though, and you might be wondering why you'd use them, how they differ from branches, and why they&

Why Container Security Tooling Needs Its Own Evaluation Framework Container adoption keeps outpacing security maturity in most organizations. Traditional endpoint protection was never designed for ephemeral, highly dynamic containerized environments, and it often fails to provide the visibility these workloads demand—agents assume persistent endpoints with stable operating systems, and
AI Security
The Backlog Problem AWS Is Trying to Solve On June 17, 2026, at its New York Summit, AWS launched Continuum—a security platform that uses frontier AI models to discover, validate, and remediate software vulnerabilities across a customer's environment with limited human intervention. Continuum for code vulnerabilities, the

The Pipeline Image That Got Out of Hand I took over an existing Kubeflow pipeline from another ML engineer. First thing I checked: image size. 3.17 GB. The DevOps team agreed that was unacceptable for a pipeline running on every model retrain. The goals were simple: reduce the size
