Stitch is a vibe design tool with an AI-native canvas that can hold and reason across images, code, and text simultaneously. The design agent understands users' entire canvas context, allowing them to swap images, generate product briefs, or mix mobile and desktop screens on the same canvas. Users can vibe design with just their voice, and also ask for design critiques and variations. The tool creates instant prototypes so users can preview the interactive app flow.

Amazon's contract renewal negotiations with the US Postal Service have fallen apart. The company plans to sharply reduce the number of packages it sends through the Postal Service when the contract expires at the end of September. It has submitted a bid as part of the Postal Service's auction process with the hope of continuing the partnership, even at a reduced level. Amazon last year committed to spending roughly $4 billion by the end of 2026 to triple the size of its rural delivery network.

Starlink is a true technological leap over every other form of airline Wi-Fi. The older forms of satellite Wi-Fi are fundamentally constrained by the laws of physics. Starlink's network can provide global coverage, and its lower orbit means that planes are much closer. However, the lower orbit also means much more damage to the satellites, causing them to degrade in about five years.

TransAstra, a Los Angeles-based company, plans to fly out to a smallish, near-Earth asteroid, throw a large bag around it, and bring the body back to a safe gathering point near Earth. One of its customers has agreed to fund a feasibility study of the mission. The study will be completed by May, after which the company will further refine its mission plan. If fully funded, the mission could rendezvous with an asteroid as early as 2028.

The Machine Payments Protocol is an open protocol for machine-to-machine payments. It allows developers to charge for API requests, tool calls, or content. Agents and apps pay per request in the same HTTP call. The protocol works with stablecoins, cards, and bank transfers in any currency.

OpenAI Codex is a coding agent that can write features, fix bugs, answer questions about codebases, and propose pull requests. Each task runs in its own isolated cloud sandbox, and users can assign multiple tasks in parallel while monitoring progress in real time. The system has three layers: the agent loop, prompt and context management, and the multisurface architecture that lets one agent serve many different interfaces. Understanding how the system works helps users work more effectively.

The field of computer science is changing as AI is now able to perform many of the tasks expected of junior developers. This is causing some students to feel apathetic about their career potential in the field. Teachers face challenges with figuring out how to teach the fundamentals that students will need to become senior engineers without the experience that working as a junior provides.

Local models can often run faster than large proprietary models, and without much decline in performance. Faster responses mean quicker and more revision cycles. Some tasks need the increased performance of larger models, but many everyday tasks will benefit more from tighter feedback loops. The smartest AI is not always the best AI to get the job done.

Intercom's internal Claude Code plugin system has 13 plugins, over 100 skills, and hooks that turn Claude into a full-stack engineering platform.

Sashiko ingests patches from mailing lists, analyzes them using AI-powered prompts, and provides feedback to help maintainers and developers ensure code quality and adherence to kernel standards.

Coding agents can't reliably fill in missing clarity and detail as they aren't mind readers, and even if they were, there's not much they can do if your own thoughts are confused.

Any time someone insists on a method for how to build a successful startup, you should do something different.

Software has always wanted to be free, and it eventually will be, so the business of software needs a different approach.

Meta's new Creator Fast Track program offers creators with an established following guaranteed monthly payments and increased reach on Facebook.
