Halfway through each month, our newsletter for developers: The Dev Times, brings three reads that our own developers found interesting on the web, and two Transloadit updates that may interest you.

Boomerang – instant, disposable file sharing

Boomerang – instant, disposable file sharing

Boomerang is a new, lightweight and simple way to send files without sign-ups or setup, created by one of the founders behind the file sharing giant WeTransfer, Ronald Hans. Drop in a file or folder (up to 1 GB), upload, and share the link. Everything will automatically expire after a week, keeping things tidy and private. It’s perfect for quick hand-offs, design exports, logs, or any “just-need-to-send-this” moment. Try it ›

LiftKit: a UI framework based on the golden ratio

LiftKit: a UI framework based on the golden ratio

The golden ratio has fascinated humans for millennia, and it has seen widespread use in art, architecture and mathematics. Thanks to LiftKit, it now has a place in UI design as well. LiftKit is an open-source design system and component library that bakes this golden ratio into spacing, typography, and sizing to make interfaces feel “oddly satisfying”. It ships React/Next.js components, utility classes, and a theme controller for dynamic color, with optical spacing fixes for common UI quirks, such as icon button padding and card line-height. Check out the examples on the website to get a better idea of the meticulous levels of detail the team went to while designing these components. Explore LiftKit ›

V8 makes JSON.stringify more than twice as fast

V8 makes JSON.stringify more than twice as fast

The V8 team has sped up JSON.stringify by more than 2 times with a new side-effect-free fast path and an iterative serializer that avoids deep recursion limits. They’ve also specialized for different string representations and swapped out the number-to-string algorithm for further gains. In practice, this means snappier serialization for network requests, localStorage saves, and logs – which you'll start to notice in the form of free performance gains on your site as this update rolls out.

Control how long your data is stored

Control how long your data is stored

You can now fine-tune how long Transloadit keeps your Assembly Status JSON and temporary transcoding results. Previously, these were fixed to 90 days for metadata and 24 hours for temporary files. You can now set workspace-wide policies and override them per Template – dialing them up or down to fit compliance, cost, or workflow needs. Immediate purging is also possible, with the usual caveats around replays and debugging. Learn more ›

Build a resumable file downloader in Go (with concurrent chunks)

Build a resumable file downloader in Go (with concurrent chunks)

Downloading large files can be flaky. In this DevTip, we walk you through building a robust Go downloader that supports HTTP range requests, resumes after interruptions, fetches chunks concurrently to maximize bandwidth, and shows real-time progress. It covers error handling, retries, connection pooling, and a complete CLI example that can be adapted to your needs. Check it out ›
