<strong>JSON-LD Explained for Personal Websites (11 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
JSON-LD is a structured data format that helps web crawlers understand the semantic structure of webpages, potentially leading to richer search previews and improved SEO. To implement JSON-LD, users can insert specific scripts within the head section of their HTML, defining elements such as the website, its owner, and various page types.

<strong>I Stored a Website in a Favicon (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
A favicon, typically serving as a small icon for a website, can function as a storage medium for data by embedding HTML content within its pixel values. This process involves converting the HTML into bytes and encoding them into the RGB channels of the favicon, allowing the browser to extract the information using JavaScript.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Temporary Cloudflare Accounts have been introduced for easier deployments for AI agents, removing the need for human sign-up processes that typically involve browser-based authentication and multi-factor prompts.

<strong>The Minimum Viable Unit of Saleable Software (8 minute read)</strong>
</span>

<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The decision to build or buy software has changed, as LLMs allow for cheaper software development but still involve maintenance and oversight costs. A “zone of viability" is introduced where software must strike a balance between cost and complexity. It is more practical to buy software than to build it when prices are reasonable and rebuilding efforts are substantial.
