TLDR 2026-06-29

HEALTHCARE'S HIGHEST-LEVERAGE DECISION IS A BRUTAL DATA PROBLEM.
GARNER IS SOLVING IT. (SPONSOR) [4]

Which doctor you see is the single biggest factor in your healthcare
outcomes Ä yet there's no transparency into physician performance.
Garner ranks doctors on quality and cost across one of the country's
largest medical datasets: 320M+ patients, 60B+ claims, 550+ clinical
metrics. Unifying messy data, provider attribution, scaling quality
metrics Ä there's no textbook for it. We built the methodology and
push it further with AI.

We're Series E and have doubled five years running.

Want real problems with real stakes? We're hiring across R&D.

SPACEX PLANS TO LAUNCH STARLINK MOBILE SERVICE IN THE US (5 MINUTE
READ) [7]

SpaceX plans to launch a new Starlink mobile service for customers in
the US. The company is considering building its own terrestrial mobile
network in the country. The new retail offering would put SpaceX in
direct competition with Verizon, AT&T, and T-Mobile. Some analysts say
that the idea may be a gamble to extract better deals from the
company's telecom partners, as it would cost billions of dollars to
roll out the required infrastructure.

ZUCKERBERG URGES META TO EXPLORE WORKING WITH POLYMARKET AND KALSHI
(6 MINUTE READ) [8]

Meta is building an app that allows people to make bets on
practically anything, similar to Polymarket and Kalshi. Arena, which
is now a top priority within Meta, will use points instead of real
money and is aimed at 18- to 34-year-olds. The company is now actively
trying to form partnerships with Polymarket and Kalshi, but it is
unclear what kind of arrangement Meta is seeking. If released, Arena
will be a stand-alone app, but Meta eventually plans to integrate
parts of it into Facebook and Messenger.

SCIENCE & FUTURISTIC TECHNOLOGY

WHY THE WEST STOPPED MAKING LAND (18 MINUTE READ) [9]

Around 8% of the land in the major coastal cities in the US was
underwater in the 1890s. Some cities, like Boston and Charleston, have
doubled in size by reclaiming land. The demand for land is now higher
than ever, but the country has virtually ceased to reclaim any at all. Regulations introduced in the 1970s made it enormously expensive to
reshape the landscape. Lifting these legal barriers could mean
hundreds of thousands of new homes near the centers of the country's
most valuable cities.

APPLE AND AUDI ALUMNI HAVE MADE A LUXE EV BASED ON THE MOON BUGGY (4
MINUTE READ) [10]

Amble, a European electric car company, has released a $25,000
electric buggy designed for places where a normal car feels out of
place. The Amble One has a range of more than 60 miles with a top
speed capped at 40 miles per hour. It takes five hours to charge the
vehicle from any standard home socket. The vehicle weighs under 450
kilograms, which allows it to drive on public roads in Europe without
being treated as a car.

PROGRAMMING, DESIGN & DATA SCIENCE

USING LOCAL CODING AGENTS (37 MINUTE READ) [11]

A local setup is a viable alternative to using proprietary services
for many coding workflows. Running agents locally makes them
transparent, inspectable, and free to run apart from hardware and
electricity costs. This tutorial walks readers through how to set up a production-ready coding agent with a fully local stack. The agent uses
a locally served LLM with a coding harness that allows it to read
files, make edits, run commands, and verify changes.

FINTECH ENGINEERING HANDBOOK (70 MINUTE READ) [12]

This handbook describes the most important patterns used in software engineering when money is the primary focus of the system. It aims to
provide a comprehensive understanding for people entering fintech,
those already in it, and those outside the industry. The guide follows
three principles: no invented data, no lost data, and no trust. Money
can't be created out of nowhere, everything that happens to money has
to be tracked and persisted, and everything must be verified.

INTEL'S CHIP BUSINESS SHOWS SIGNS OF LIFE AFTER YEARS OF STRUGGLE (8
MINUTE READ) [15]

Intel was flailing until the US government intervened and took a 10%
stake in the company last summer. The company is now showing signs of
a turnaround, with its value having more than tripled. Intel has since
added big customers like Nvidia and Apple. The AI boom has reshaped
the chip market and benefited Intel greatly.

TRUMP ADMINISTRATION ROLLS BACK PART OF ANTHROPIC MODEL BAN (3 MINUTE
READ) [16]

Anthropic is now allowed to serve its Mythos 5 model to trusted
companies and government partners. Fable 5 remains restricted and
restrictions on Mythos 5 still apply to entities that aren't trusted
partners. The US government is racing to implement an executive order
recently signed that gives federal cybersecurity officials a say in AI
model evaluation. The industry is in limbo and will have to react to case-by-case decisions by the administration until the order is
implemented and standards are in place.
