<strong>‘Tokenmaxxing' as a weird new trend (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
"Tokenmaxxing" is a new trend where employees, motivated by internal leaderboards at companies like Meta, Microsoft, and Salesforce, maximize their AI token usage, resulting in financial waste, an emphasis on quantity over quality, and system outages. While Meta abolished its leaderboard after media backlash, Shopify successfully implemented a "usage dashboard" with human review and circuit breakers to encourage productive AI use and prevent wasteful burning.

<strong>Shopify Speed Optimization: Fixing The Real Bottlenecks (23 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Structural bottlenecks slowing down Shopify stores can be addressed by optimizing above-the-fold content through reduced hero image sizes, placeholder videos, and efficient image compression. Managing JavaScript bloat via conditional loading and utilizing network prioritization techniques like preloading further improves the user experience further.

<strong>How good engineers write bad code at big companies (10 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Big tech companies often produce sloppy code because frequent internal reorganizations and high turnover mean systems are mostly maintained by engineers working outside their expertise. This technical debt is an intentional trade-off prioritized over deep expertise to maintain organizational flexibility and rapid redeployment capabilities.

<strong>Why I spent years trying to make CSS states predictable (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Tasty is a compiler that addresses the unpredictability of traditional CSS by declaratively defining property states and priorities to generate mutually exclusive selectors. This approach removes cascade conflicts and guarantees deterministic behavior, making it easier to manage and extend complex design systems.

This is a collection of small UI polish details that compound into better-feeling interfaces: balanced text wrapping, concentric border radius (outer = inner + padding), tabular numbers, antialiased font smoothing, contextual icon animations, interruptible CSS transitions over keyframes, and more. The tips are also packaged as an open-source skill installable via npx.

<strong>An update on recent Claude Code quality reports (10 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Anthropic investigated user reports of degraded Claude Code quality, tracing the issue to three unintentional changes, such as altered reasoning and a verbosity-reducing prompt, all of which have since been resolved as of April 20. In response, Anthropic is implementing stricter testing, better code review, and tighter system prompt controls.
