  • How to Use OpenAI Codex Subagents Step by Step

    This story was originally published on HackerNoon at: https://hackernoon.com/how-to-use-openai-codex-subagents-step-by-step.


    When you use Codex, putting too many tasks into a single conversation makes the model slow and unreliable. To solve this problem, I recommend using subagents.

  • I Priced the Same Inference Workload on 4 GPU Clouds. Egress Was the Catch

    This story was originally published on HackerNoon at: https://hackernoon.com/i-priced-the-same-inference-workload-on-4-gpu-clouds-egress-was-the-catch.


    A reproducible 2026 cost model pricing one inference workload across six GPU clouds, and why egress, not GPU-hours, decides a third of the bill.

    Most GPU cloud comparisons stop at dollars-per-GPU-hour, which is only half the bill. Pricing one identical inference workload (1 GPU, 24/7, 30 TB/month egress) across six clouds from their published rates shows egress quietly eating 22–31% of an AWS, Azure, or GCP bill, a line item that's $0 on providers that don't meter it. The real lesson: egress is an architecture decision, not a billing surprise, so model it before you commit.

  • Spec-Driven Development Is the New Developer Superpower

    This story was originally published on HackerNoon at: https://hackernoon.com/spec-driven-development-is-the-new-developer-superpower.

    The article argues that as AI makes implementation cheaper, the quality of specifications becomes the primary determinant of software quality. It introduces a framework built around Specs, Skills, Workflows, and Proof, showing how structured engineering artifacts help AI agents produce safer, more reliable, and more maintainable software while redefining the role of senior engineers.

    Traditional Android debugging assumes you have both a computer and a phone. Code on the Go changes that by bringing the entire debugging workflow onto a single Android device. This post explains the technical challenges of building phone-native debugger, including privileged access, process management, and breakpoint handling, and how the team solved them while ensuring the debugger only works on the device running Code on the Go. The result is a fully self-contained Android development experience that lets developers write, build, run, and debug apps anywhere, without a laptop or internet connection.

    Python functions created inside loops often return the same value because closures capture a variable, not a snapshot of its value. This behavior is known as late binding. When the loop finishes, all functions reference the final value of the loop variable. This article explains why it happens and demonstrates two standard solutions: default argument capture and factory functions.
