ANTHROPIC EXPECTS TO MATCH OR TOP SPACEX'S RECORD IPO SIZE (4 MINUTE
READ) [5]

Anthropic is preparing to file for its potential mega-IPO as soon as
the end of this month. It is expecting to match or beat the size of
SpaceX's record-setting debut. Ahead of the IPO, Anthropic is set to
finalize a revolving credit facility that will raise more than its
roughly $10 billion target. The AI lab is considering adopting
super-voting shares that would give its co-founders greater control
over the company.

SLACK LAUNCHES SLACK CODE, WHERE TEAMS AND AI AGENTS BUILD TOGETHER
(4 MINUTE READ) [6]

Slack Code adds project-specific channels where teams and AI agents
write, review, and ship software together. The work happens inside the
chat app rather than in a separate browser tab. Users tag a coding
agent from any conversation, and it spins up a dedicated code channel
that automatically archives itself after tasks end. Everyone in the
channel can follow the work. Slack Code is now available in any Slack
plan.

ELON MUSK GIVES A TIMELINE FOR SPACEX'S FIRST STARSHIP CATCH ATTEMPT
(3 MINUTE READ) [7]

Elon Musk predicts that SpaceX will likely be able to catch the
Starship upper stage with its launch tower arms in a few months. The
first reflight of a Starship vehicle is expected by the end of 2026 or
early 2027. Catching the upper stage of Starship would mark a major
milestone as it allows both stages to return directly to the launch
site for quick refurbishment and reuse. Musk has long said that true reusability is essential for making humanity a multi-planetary
species.

TESLA'S AUSTIN ROBOTAXIS ARE NOW FULLY DRIVERLESS, TRACKING SHOWS (7
MINUTE READ) [8]

A crowdsourced project called Robotaxi Tracker noted that all 170
rides by Tesla's robotaxi service in Austin logged over the past
fortnight didn't have a human safety monitor on board. Tesla doesn't
publish fleet data and usually doesn't answer press questions, so the crowdsourced data is one of the few sources of information available.
The expansion of completely driverless robotaxi vehicles is not
confined to Austin. Roughly 30 driverless Teslas have been spotted
running in Dallas and Houston over the past week.

PROGRAMMING, DESIGN & DATA SCIENCE

GLEAN COSTS 75% LESS PER TASK (SPONSOR) [9]

AI work gets expensive fast, especially when models burn tokens
rebuilding context from fragmented systems. Glean skips that tax with enterprise context and intelligent retrieval built in -- see how it
stacks up against Claude Cowork [9], where it averaged $0.45 per task
vs. $1.84, a 4x cost gap that adds up fast.

BETTER BATTERIES (2 MINUTE READ) [10]

The problem with Python's stdlib is its uneven quality. However,
that's actually Python's core advantage - it makes functionality
available early. Rust still doesn't have an API to get a stream of
random bytes from the OS. This is possibly because, while it is an
easy technical problem, it requires tricky organizational
architecture, and the Rust team's capacity to execute design decisions
is limited.

THE KIDS ARE REALLY ALRIGHT (4 MINUTE READ) [11]

Junior engineers still add capacity to an organization. The work of
an engineer is to solve a customer problem with software while
managing the technical complexity that exists in deciding how to.
Staff engineers manage a lot of complexity, and junior engineers
manage a little complexity, but the role is the same. Technical
decision-making is still important, and junior engineers add to it,
enabling organizations to do more.

THE BRAINS WHO POWERED CHINA'S SURPRISING AI LEAP (13 MINUTE READ)
[12]

The rapid rise of Chinese AI models has sparked a host of questions
about how these labs get so far so fast. However, the careers of the
founders of two of the biggest Chinese labs show that China's AI push
is nothing sudden. Tang Jie, who founded Z.AI, has been working on
machine learning for about a quarter of a century. Yang Zhilin, who
leads Moonshot AI, was Tang's former student.

THE END OF OPEN SOURCE (20 MINUTE READ) [13]

Intelligence services were never limited by what they could steal,
but what they could read. Reading was the expensive part, so
collection had to be selective. Every company that told itself it was
too boring to be a target was relying on a foreign analyst's workload.
AI removes this constraint. Closed source only removes your ability to
see your exposure - it doesn't remove it.
