Insights, tutorials, and best practices from our team of experienced developers.
dxpdf converts Word documents to PDF without Office, LibreOffice, or a cloud API. Version 0.5.0 is the release where it stopped quietly assuming every document is written in English — UAX #14 line breaking, UAX #9 bidirectional text, and CLDR-driven numbers and dates that follow the document's own language. Here is what shipped, the design decisions behind it, and the measured numbers.
Every CI pipeline eventually has to get a build onto a server, and most teams solve it with SSH keys in secrets and a copy-pasted rsync script. We built Orosu instead — an open-source Rust tool that turns deployment into an authenticated, bounded WebSocket job instead of an open shell. Here is the problem it fixes, how it works, and where its edges are.
What Flutter app maintenance actually costs after launch — the 15–25%-of-build-cost rule of thumb, what drives the number, and where a single codebase saves real money.
A deep dive into how end-to-end encryption is established and kept secure over time — the X3DH handshake, the Double Ratchet algorithm behind Signal and WhatsApp, group messaging with sender keys, and an honest look at what E2EE protects and what it does not.
Realistic Flutter build timelines for 2026 — 6–12 weeks for an MVP, 3–6 months for a business app, 6–12+ months for a regulated one — phase by phase, plus the variables that actually move the date and the ones that only look like they do.
The actual process behind a Flutter build — discovery, design, architecture, iterative development, QA, release, and maintenance — run as short feedback loops rather than a waterfall. What happens in each phase, what you get out of it, who is in the room, how long it takes, and the specific places the process breaks.
We let agents write a large share of our Flutter code, and we review a lot of Flutter written by agents nobody supervised. The difference is not typing speed — it is seven decisions an unsupervised agent gets wrong every single time: it recomputes derived state instead of keeping one source of truth, ships no tests or benchmarks, wires complex async into if-pyramids instead of streams, treats design tokens as constants instead of a Theme, invents a new UX vocabulary on every screen, concatenates strings where ICU is required, and simplifies uniformly instead of knowing where complexity has to stay. Here is what each one looks like in Dart, why the agent lands there, and what we do instead.
The engineering behind ExtraETF — how we fan live market data out to many clients with a Go WebSocket service, how we build performant financial charts natively in Flutter, and the tradeoffs we would revisit in 2026.
Most "white-label" app shops just reskin one binary — and Apple guideline 4.2.6 rejects exactly that. Here is the architecture we use to ship 20+ genuinely distinct branded apps from a single Flutter codebase: per-tenant authentication and server-driven content that make each app a real standalone product, not a duplicate.
Three ways to hire Flutter talent in 2026 — in-house, agency, or staff augmentation — compared on cost, speed, and risk, with real rate ranges and a decision framework for founders and CTOs.
AI now writes a large share of the code in any serious shop — 84% of developers use it daily. We lean into that on purpose. Letting agents produce the code frees our engineers to do the work AI is worst at: architecture, flexibility, and the whole-system decisions that determine whether software survives its second year. Here is how we actually build in 2026, why we moved the human effort up the stack, and how we keep AI-written code from turning into the tangled codebases we audit every week.
Your AI-built app may already be live, and the security holes are only part of the story. We audited dozens of codebases built with Cursor, Claude Code, Bolt, Lovable, and long ChatGPT sessions, and the same eleven problems recur almost every time: hardcoded secrets, no input validation, authentication that checks the box but not the request, zero tests, no error handling on the unhappy path, N+1 queries, stale dependencies with known CVEs, rampant duplication, no consistent architecture, callback hell instead of proper async patterns, and no awareness of the deployment environment. Here is what each one looks like, why AI produces it, and how we fix it.
