Notes on data engineering and building things. 2026-06-21T00:00:00Z https://qrahman.com/ Q Rahman 2026-06-21T00:00:00Z https://qrahman.com/blog/hello-world/ <p>This is the first entry. To add another, drop a new folder under <code>src/posts/</code> with an <code>index.md</code> inside and write in Markdown — the post page, the blog index, and the RSS feed all update themselves on the next build.</p> <p>Images work too. Put the file in the post's folder and reference it relatively:</p> <p><picture><source type="image/avif" srcset="https://qrahman.com/blog/hello-world/rrNQu1Ozx3-480.avif 480w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-960.avif 960w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-1200.avif 1200w" sizes="auto"><source type="image/webp" srcset="https://qrahman.com/blog/hello-world/rrNQu1Ozx3-480.webp 480w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-960.webp 960w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-1200.webp 1200w" sizes="auto"><img loading="lazy" decoding="async" src="https://qrahman.com/blog/hello-world/rrNQu1Ozx3-480.png" alt="A test gradient" width="1200" height="600" srcset="https://qrahman.com/blog/hello-world/rrNQu1Ozx3-480.png 480w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-960.png 960w, https://qrahman.com/blog/hello-world/rrNQu1Ozx3-1200.png 1200w" sizes="auto"></picture></p> <p>That image is automatically resized to several widths and served as AVIF/WebP with a fallback, so it stays fast on every device.</p>
