Postman’s annual user conference (April 30 - May 1 in San Francisco) is shaping up to be one of 2024’s top developer events—featuring workshops [6], in-depth presentations, and an awesome after-party. Hear from Postman experts and industry leaders [7] including:
React 19 introduces several significant improvements designed to streamline development and boost application performance. Key features include a performance-enhancing compiler, simplified form handling with Actions, server-side rendering optimizations with Server Components, and better integration with Web Components. The update promises faster rendering, smoother user experiences, and easier development workflows.
SVG spinners are simple to create and offer a visually appealing way to indicate loading progress. This guide demonstrates how to build basic spinners using SVG's circle element and attributes like stroke-dasharray and stroke-dashoffset. To make the spinners dynamic, CSS animations are used to rotate the circle or animate the stroke attributes.
Feature flags are a valuable tool for separating code deployment from feature releases, but their overuse can complicate codebases and hinder testing. Too many feature flags leads to difficult testing and complex code and creates excuses for PMs to not make hard decisions like completely removing a feature. To deal with this, you should separate your feature flags into categories and deal with them differently: release toggles for merging not-ready code into production, ops toggles for features with unknown performance implications, experiment toggles for A/B tests, and permission toggles to enable different experiences for different users. Only let PMs manage the latter two and let developers remove control release and ops toggles as soon as they're done.
Most people stick to basic Git commands. This article discusses less common but powerful Git commands. One useful command is git switch, which offers safer, more focused branch switching compared to git checkout. Another is git restore, which simplifies file restoration and replaces some uses of git reset and git checkout. For large monorepos, git sparse-checkout improves performance by checking out only specific directories. git worktree enables working on multiple branches simultaneously, removing the need for stashes or multiple repo clones.
Programming languages lack built-in graph support not because graphs are too complex, but because modern languages' imperative model makes it difficult to write graph algorithms without committing to a specific graph representation. A declarative language like Datalog, based on relational algebra, is a much more natural fit for expressing graph algorithms. Datalog's ability to optimize queries based on dataset characteristics and its expressiveness makes it both performant and easy to use for graph-related tasks.

Google Cloud’s upcoming developer conference [14] is packed with immersive learning, community interactions, and a peek into the future of Google Cloud — with a focus on the latest tools for building AI-powered applications [15].
* 500+ sessions [16] (101 - 301 level) across 10 different tracks * Cutting-edge AI demos [17] and interactive learning
ExpressoTS is a Typescript and Node.js framework for quickly building scalable, easy-to-read and maintain server-side applications.
JSR is an open-source package registry for JavaScript and TypeScript.
Radicle is a peer-to-peer network for code collaboration built on top of Git. It is local first, secure, and enables users to run their own nodes without reliance on third parties.
The recent wave of tech layoffs has shifted power back to employers, leading to more demanding hiring processes with lengthy assignments and aggressive negotiation tactics. Job seekers are frustrated with excessive interview requirements and disrespectful treatment from some companies. Experts warn that these laborious hiring practices could backfire, especially once the market shifts.
Spreadsheets are widely used for data entry, computation, and presentation, but their design makes them prone to hidden errors and difficult to manage as complexity grows. This presents an opportunity for array programming languages, which offer a more reliable and expressive way to perform complex calculations. The Kap array programming language aims to bridge the gap between spreadsheets and traditional programming, providing a familiar spreadsheet-like interface for data entry and presentation while using an actual programming language for computation.
Meta's Messenger app for macOS uses certificate pinning to prevent users from easily analyzing network requests sent to Meta's servers. Using the Hopper disassembler, this author identifies a key function (IsUsingSandbox()) that controls certificate pinning behavior. By modifying a few bytes within the Messenger binary to force this function to return "true", the author is able to effectively disable certificate pinning and successfully intercept network traffic for analysis.
Uber developed CacheFront, a highly efficient caching layer integrated with its Docstore database, to achieve significant latency reductions (75% in P75, 67% in P99.9) and enable over 40M reads per second.
Starting today, AWS is waiving Data Transfer Out fees for customers wishing to migrate their data to another cloud provider or on-premises.
Nvidia has updated its CUDA license to explicitly forbid the use of translation layers to run CUDA software on non-Nvidia hardware.
The Kagi search engine has integrated Wolfram|Alpha's knowledge base to enhance search capabilities for computational queries.
