Fit vs Fill in image-to-PDF tools: the geometry behind cropped pages

·1 views

An image-to-PDF converter can preserve an image's aspect ratio and still produce a surprising result: the page looks full, but text near the edges has disappeared. That is not necessarily an encoding bug. It can be the expected result of Fill, combined with a clipping rectangle. In my previous article, I covered memory ownership and browser-side processing. This article focuses on a different boundary: translating image dimensions into a predictable PDF layout.

Over time, I got comfortable working with technologies like React, Node.js, TypeScript, MongoDB, Next.js, and REST APIs. But the biggest learning didn't come from the technologies themselves. It came from reading someone else's code, understanding an existing codebase, opening issues, reviewing pull requests, fixing bugs, and learning how to communicate with other developers. Being involved in open source has also taught me that you don't need

Core Web Vitals: What Cloudflare's BEACON Data Says to Fix First

I have a bad habit with performance work. I open Lighthouse, see a red number, and start fixing whatever the report lists first. Usually that's an image that's 40KB too big. It feels productive, and it moves the score, and half the time it has nothing to do with what my client's users actually wait for. So when Cloudflare released a dataset of real-user measurements from about 10,000 of the biggest sites on its network, I read the BEACON announcement with a specific question: if I had one afternoon to improve Core Web Vitals on a normal client site, where should it go?

Keeping large chart previews and CSV exports consistent

A user loads a year of minute candles, zooms out to see the whole period, then downloads a CSV. The file should retain the selected resolution even if the chart has to combine candles to draw that view. That requirement connects several parts of a browser export tool: the dataset, viewport, pagination loop, Cancel button and file writer. Each can make a different decision about how much data it needs. Those decisions should remain visible to the user.
