A content library shown as a garden of pages: thin and duplicate pages being pruned, two competing pages merging into one stronger page through a 301 redirect, and the remaining pages rising in rank

SEO & content · Jun 18, 2026

Pruning and consolidating content without losing rankings

A careful playbook for cleaning up a content library: why thin and duplicate pages drag down the whole site, how to audit what you have by traffic and intent, the keep / refresh / merge / remove decision, how keyword cannibalization happens and how to fix it by consolidating, and why the 301 redirect is the tool that lets you do all of this without losing the equity you built.

Why the preview now matches the export: rebuilding a music-visualizer render engine

A deep dive into the v2.0 export engine: why preview and export drift apart in the first place, what "seekable" means and why scrubbing used to break, how beat-sync stays locked between the live preview and the rendered file, why every mode is now visually distinct, and what an honest in-browser render pipeline owes the user.

The vector-versus-raster distinction that actually decides the choice, where SVG is unbeatable (logos, icons, illustrations) and where it falls apart (photos), how PNG and WebP differ for the raster cases, the transparency and crispness traps, and a simple decision rule you can apply to any graphic on your site.

A plain-English explanation of the technique that makes on-device AI possible: why a model’s size is the gatekeeper for running it in a browser, what a model actually is under the hood, how quantization stores its numbers in fewer bits for a roughly four-times reduction, why models tolerate the lost precision, what it costs in accuracy, and how it combines with distillation and pruning.

Code-splitting a large web app: how lazy routes keep it fast

How the NSS Background Remover stays fast to open despite many tools: route-level code-splitting so each tool is its own chunk, lazy boundaries that defer the heavy parts, deferring multi-megabyte AI models until a tool actually needs them, and the measurements that tell you whether any of it worked.

Browser memory management: not crashing the tab on a 4K export

How to keep a heavy in-browser export from crashing the tab: where the memory actually goes (decoded pixels, not file size), why peak usage is what kills you, tiling and streaming so you never hold the whole thing at once, releasing buffers and bitmaps explicitly, and degrading honestly when a device cannot do the job.

Static-first: when a small site doesn't need a single-page app

A plain-English case for building static-first instead of reaching for a single-page app by reflex: what a SPA actually costs in load time, complexity, and fragility; why most small sites are content with a little interactivity, not apps; what progressive enhancement buys you; how to decide per-feature rather than per-site; and the narrow cases where a SPA genuinely earns its keep.

A tool’s first screen designed to teach — a single clear drop-zone action, a sample to try, and a one-line hint — turning an empty state into onboarding without documentation

Web & UX · Jun 16, 2026

The first-run experience: onboarding a tool nobody reads docs for

How to onboard a tool that no one reads docs for: why the first screen is the only instruction most users will ever see, designing the empty state to teach rather than just sit there, making the single most important action unmissable, getting to a first result fast, and layering help so it is there without being in the way.

A clear-eyed estimate of the traffic a free, ad-supported tool needs to fund itself: what RPM really means and why it is the number that matters, the genuinely small cost base of a serverless tool, the simple break-even math, why a new tool earns far less per visit at first, and why traffic quality changes the answer as much as quantity.

A clear-eyed look at the seasonality of ad income and how to plan around it: why ad rates swing by season regardless of your traffic, the danger of treating a Q4 peak as your baseline, budgeting to a trailing average rather than the high, building a buffer that smooths the trough, and separating the revenue cycle from your spending decisions.

A practical approach to image metadata when there are too many images to handle by hand: what metadata actually covers, why alt text is for people before search engines, how to use AI to draft alt text without shipping confident nonsense, generating filenames and stripping EXIF as a pipeline step, and a build-time check that keeps the whole library honest.
