<strong>PostgreSQL Bloat Is a Feature, Not a Bug (14 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
PostgreSQL bloat is a fundamental design feature where databases grow and queries slow down due to the accumulation of old data versions. This occurs because the database's Multi-Version Concurrency Control (MVCC) creates new physical tuples for every update and only marks old ones as obsolete upon deletion, rather than overwriting or erasing them. These "dead tuples" consume disk space, force the system to perform unnecessary I/O by scanning full pages, and contribute to index bloat.

<strong>Virtual Scrolling for Billions of Rows — Techniques from HighTable (30 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
HighTable is a React component that lets you scroll through billions of rows in a browser table smoothly. It only loads and renders the ~30 rows you can actually see at any given time. The tricky part is that browsers cap element heights at ~17M pixels, so the creative solution is to use a downscaled scrollbar plus a dual scrolling mode (small gestures scroll locally with pixel precision, big ones jump globally).

Vercel found that WebStreams were a huge bottleneck in Next.js server rendering. The streams were burning CPU on Promise allocations for every chunk. Vercel built fast-webstreams, a drop-in replacement that collapses piping chains into a single Node.js pipeline() call with zero Promises per chunk, with the end goal of merging this package into Node.js itself soon.

<strong>When interfaces become disposable (9 minute read)</strong>
</span>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
A new parent used AI coding to create a custom interface for his Fitbit data, addressing his unique sleep tracking needs that the standard app couldn't fulfill. This bespoke tool is an example of disposable software. AI agents are increasingly enabling users to bypass traditional interfaces and directly access product capabilities via APIs, creating a fragmented landscape where custom solutions are easily generated.

There's widespread acceptance of AI-generated slop in writing. Despite the allure of AI's efficiency, genuine writing is an irreplaceable process of solitary thought, labor, and public engagement. It's good to be aware of cognitive debt from over-reliance on AI.

This shift is especially important as AI agents begin automating PR and distribution, potentially creating "black box" processes that muddy operational insights.
