<strong>How to Build an OS Without Being a Degenerate (11 minute read)</strong>
</span>
</a>
<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Building an operating system effectively involves labeling your project honestly, starting from an established OS, and engaging in reading to understand the components thoroughly before coding. There needs to be a focus on creating genuine drivers and collaborative argumentation within a team are necessary for meaningful development in OS creation.

<strong>Curiosity reduced the heap size by 60% (3 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
An agent kept filtering a Ruby warning out of its test output, and chasing it down revealed that the OpenTelemetry AWS instrumentation was force-loading about 200 SDK service classes at boot when the app only needed a handful. A small patch that skips unresolved autoloads cut VM classes and heap roughly 60% and boot time 36%. Following an odd signal for five minutes is now cheap enough to do routinely.

<strong>Why DoorDash, Instacart, and Uber Eats Integrated LLMs Into Search Three Different Ways (10 minute read)</strong>
</span>

<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Food search breaks keyword retrieval every way at once with synonyms, typos, bilingual collisions, a long tail with no conversion data, and hard constraints where “vegan chicken sandwich” scores as similar to something that violates the whole point. Three companies solved it off the same research base and landed at different depths of LLM integration: DoorDash keeps it offline enriching a knowledge graph, Instacart puts it at query understanding with a head/tail split, and Uber Eats makes a fine-tuned Qwen the embedding backbone of two-tower retrieval.

<strong>Developers are attached to tools because tools encode trust (14 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Developers often struggle to trust new coding tools, especially as AI-driven systems become more integrated into the software development lifecycle. The shift to these tools can challenge established processes and cultural practices, leading to broken workflows despite having advanced technology at their disposal. To regain trust, teams need to establish clear, defined workflows that prioritize human oversight and accountability.

<strong>My Agentic Coding Setup, July 2026 (21 minute read)</strong>

<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Running agents unattended, with approvals off, in parallel, with work that survives closing your laptop and follows you to your phone, turns out to require getting development off your local machine entirely, onto a disposable Ubuntu VM joined to a Tailscale tailnet. Tailscale does the heavy lifting (SSH from any network, HTTPS certs so agent dev servers are secure contexts and stay private), with git worktrees and a Portless wrapper keeping parallel agents from colliding. Safety is handled by blast radius rather than prevention: push to GitHub constantly, treat the VM as expendable.

This is a React hook that exposes your app's functions as callable tools for browser AI agents via the experimental WebMCP spec, wrapping the imperative document.modelContext.registerTool API so tools register on mount and unregister on unmount. This means that the agent only ever sees tools for what's actually rendered, making it useful to prototype with.

<strong>SwiftUI After 7 Years: A Story of Mediocrity (17 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Seven years after its launch, SwiftUI is still plagued by performance issues, unpredictable layout behavior, and a frustratingly inconsistent API, leaving many developers feeling like they are working with a perpetual beta. The framework's promise of cross-platform support and ease of use has failed to materialize in practice, resulting in a landscape where developers must constantly implement workarounds and deal with a lack of backward compatibility.
