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.
2026.03.19·threadreaderapp.com·5 min read·TLDR 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.
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.
2026.03.19·arstechnica.com·4 min read·TLDR 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.

The field of computer science is changing as AI is now able to perform many of the tasks expected of junior developers.

OpenAI's 'do everything at once' strategy has put the company on the defensive.

OpenAI has taken steps towards an initial public offering that could open in the fourth quarter of this year.
2026.03.17·links.tldrnewsletter.com·5 min read·TLDR Nvidia introduced a huge array of new products at its annual GTC conference on Monday, ushering in new hardware and software geared towards running AI models more quickly and efficiently. The company has been signaling for most of the last year that it would increasingly focus on inference computing going forward. Its traditional GPUs are not ideal for inference because they consume a large amount of energy and don't come with enough attached memory. Nvidia expects to sell $1 trillion worth of its Blackwell and Rubin chips, focused on inference, by the end of 2027.

Specifically engineered for size-, weight-, and power-constrained environments, the chips will be used on space missions led by multiple companies. There are still engineering hurdles to overcome in building orbital data centers. For example, in space, there's no convection, so Nvidia has to figure out how to cool the system with just radiation.
The entire neuronal diagram of the fruit-fly brain was mapped in 2024. Later research showed the map can be used to predict behavior. The brain map has now been uploaded into a digital environment. It's not a simulation - the fly's 'sensors' are being activated by the digital environment and the neurons are responding. The digital fly appears to behave in the digital environment in reasonably fly-like ways. A video that explains the yet-published experiment (with footage of the digital fly) is available in the article.

Investments in developer productivity can provide unexpected dividends when agents are included in the workflow. Stripe's Minions work in isolated environments with hybrid orchestration that mixes deterministic guardrails with agentic flexibility.

The bottleneck has moved to managing long-horizon tasks and deploying agents in regulated settings. The human role is shifting to planning, evaluating, and steering. Enterprise adoption is gated by permissioning, sandboxing, and regulatory caution more than by model capability. Slop and convergence are real concerns, and context remains unsolved.
