STITCH BY GOOGLE (5 MINUTE READ) [5]
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 SAYS US POSTAL SERVICE ‘WALKED AWAY AT THE ELEVENTH HOUR' IN NEGOTIATIONS (3 MINUTE READ) [6]
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.

A PRIVATE SPACE COMPANY HAS A RADICAL NEW PLAN TO BAG AN ASTEROID (4
MINUTE READ) [7]
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.
WHY IS STARLINK ON PLANES SO GOOD? (6 MINUTE READ) [8]
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.

HOW OPENAI CODEX WORKS (12 MINUTE READ) [10]
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.
MACHINE PAYMENTS PROTOCOL (WEBSITE) [11]
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.

ASK HN: WHAT IS IT LIKE BEING IN A CS MAJOR PROGRAM THESE DAYS?
(HACKER NEWS THREAD) [12]
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.
THE ROBOTIC TORTOISE & THE ROBOTIC HARE (1 MINUTE READ) [13]
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.
