A synced PDF preview needs two separate pieces of code, not one run backward. ModernTex shipped the harder direction wrong before getting it right, and the gap shows what counts as correct versus what counts as working.

Converting cleanly between LaTeX and Word is the easy half of a coauthored manuscript. The harder half is getting a reviewed Word file's tracked changes and comments back into your LaTeX source without retyping them.

About 500 photographs from the Alps, Japan, Iceland and more are for sale as prints. Where to find them, and the metadata field that cut 65 listing titles short.

Academics maintain their professional history in a dozen scattered places. When tenure reviews, grant applications, and annual reviews arrive, reconstructing the record from scratch is the problem.

Building GlobePin's App Store analytics pipeline, I wrote code that treated absent data and broken requests identically. Two independent bugs, each enough to return nothing, sat undetected until Apple generated its first real reports.

A visual TikZ designer with live preview, and a Table Editor that pastes straight from Excel — both still write plain LaTeX underneath.

A response letter can address every reviewer comment without actually resolving the underlying concern. This is how a researcher uses Response to Reviewers to check that gap before resubmitting.

The kits page had visitors but Stripe showed no sessions. Here is how I instrumented the checkout boundary without adding click handlers to every buy button.

Most missed citations aren't papers you forgot to read. They're papers in adjacent fields using different terminology for the same problem, invisible to a keyword search.

The Purplelink stats endpoint read event blobs one at a time, and the code even included a comment noting it would fail at higher volume. The failure arrived through latency rather than traffic spikes.

Many journal submission portals require a diff PDF alongside a revised manuscript. Here is how a researcher uses Purplelink's LaTeX Diff tool to produce one without a local LaTeX installation.

The Purplelink cover letter generator takes only your abstract, not the full manuscript. Here's the capability and privacy reasoning behind that design choice.

Two Purplelink tools that compute entirely in the browser had no usage data, because instrumentation relied on intercepting backend calls. Fixing that required defining what a run actually means, and the answer differed by tool.

Double-blind peer review requires more than removing your name from the title page. Grant numbers, IRB protocols, citation prose, and named software all identify you to a reviewer who knows your field.

OpenAlex stores paper abstracts as inverted indexes rather than strings. Building the Daily Digest's paper fetcher surfaced this, and the reconstruction has limits.

Paper Review scans your manuscript before submission with four adversarial passes: figure integrity, citation cross-check, a multi-persona reviewer debate, and a prioritized checklist. Here is what using it looks like from a researcher's side.

The Purplelink Daily Digest harvests 400-800 items daily and picks 20 to publish. Here's why the design uses a single AI curation call instead of scoring items one at a time.

Academic researchers who work across multiple fast-moving fields have no good daily briefing built for them. Here's why the existing infrastructure falls short, and what I built to fix it.

What caught my eye today at the intersection of cybersecurity, AI, research, and entrepreneurship. Curated every morning.

Most BibTeX errors don't come from researchers making mistakes. They come from the bibliography managers and export tools researchers trust to get it right.

PDF text extraction breaks on tables and equations. Here's how a researcher uses Purplelink's PDF to Structured Data tool to get clean, LLM-ready text out of an academic paper.

Compile to PDF, convert to and from Word, diff two versions, validate and build BibTeX, and render equations - no account, no install, nothing stored. They're live now.

Every travel tracker on the App Store solves a piece of the problem. Most miss the same things. Here's what we built differently - and why.

Your health data is the most personal data you have. Here's why we decided early on that none of it would leave your phone - and what that decision cost us.

TeXShop is from 2000. Overleaf is a web app. Neither was designed around the manuscript workflow researchers actually live in. ModernTex is.

Why I formed a software LLC, what I'm building with it, and the philosophy behind making software that's meant to last - not just ship.
