<strong>Why I (still) love Linux (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Linux provides unmatched freedom, accessibility, and longevity, even as many modern distributions drift from classic Unix principles and introduce instability in the name of progress. Despite frustrations like systemd's scope creep and corporate influence on development direction, Linux remains deeply valuable thanks to its hardware support, minimalistic distributions, and the decades of learning, growth, and reliability it has enabled.

<strong>"Good engineering management" is a fad (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Engineering management expectations swing with industry cycles: the 2000s rewarded organizational navigation, the 2010s rewarded hypergrowth-era people leadership, and the post-2022 era rewards hands-on execution as AI and economic conditions reshape organizations. These shifts are driven by business realities—not moral narratives—so the only durable path is developing broad foundational and long-term leadership skills while managing your career energy and priorities over a decades-long horizon.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Amazon Elastic Kubernetes Service (EKS) has launched a fully managed EKS Model Context Protocol (MCP) Server in Preview. The EKS MCP Server allows users to manage EKS clusters through natural language instead of complex commands, and can be integrated with AI tools like Kiro, Cursor, and Cline. Amazon Q integration also enables AI-powered troubleshooting within the Amazon EKS console. The EKS MCP Server is currently available in all AWS Commercial regions, except US GovCloud and China regions.

PgDog, a Rust-based transaction pooler and logical replication manager, can shard PostgreSQL and manage hundreds of databases and connections. As an application layer load balancer, PgDog supports multiple strategies, such as round robin, and can automatically route queries to shards, even splitting COPY commands. It is free and open-source under the AGPL v3 license. Healthchecks maximize database availability, and configuration can be tweaked at runtime without breaking connections.

<strong>Reliability lessons from the 2025 Cloudflare outage (5 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cloudflare's outage on November 18 was initiated by a configuration change, which caused its Bot Management system to exceed its file size limit, triggering HTTP 5XX errors that cascaded across multiple dependent services and took major websites like X, ChatGPT, and Shopify offline. To reduce similar risks, organizations should test dependencies with fault injection, monitor health checks, identify single points of failure, and implement failover or error-handling mechanisms.

<strong>Demystifying Determinism in Durable Execution (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Durable execution frameworks recover by re-running a function from the top and reusing previously recorded side-effect results, which means the control flow must be fully deterministic so that every retry makes the same decisions and passes the same arguments. Side effects themselves can be non-deterministic, but they must be idempotent or duplication-tolerant because they may be re-invoked if their results weren't durably recorded.
