AMAZON PLANS TO LAUNCH 5,000 NEW SATELLITES TO BEAM DATA TO IPHONES
(6 MINUTE READ) [4]
Amazon plans to launch 5,105 low-Earth orbiting satellites to build
on top of Globalstar's existing network of only a few dozen
satellites, which it acquired in an $11.6 billion deal a few months
ago. The network will power both voice and mobile data. Amazon has yet
to release pricing for its service. In the US, the satellites will use Globalstar's radio spectrum in the 1.6/2.4GHz bands, and orbit between
510 km and 580 km in altitude.

THE DATA PYRAMID IN ROBOTICS (11 MINUTE READ) [6]
Frontier LLMs were trained on text data from the internet. There's no equivalent source of physical data for robotics. All attempts to solve
and get to physical AGI involve working through this data bottleneck.
Progress is being made on many fronts, but nobody knows how much data
is enough.
ASML SLIDES ON REPORT OF CHINA STARTING DUV TOOL PRODUCTION (4 MINUTE
READ) [7]
A Shanghai-based company has started mass producing immersion deep
ultraviolet lithography tools. The unnamed firm aims to make about
five DUV machines this year and is targeting about 20 next year.
Production is still at an early stage. DUV machines are less advanced
than ASML's sophisticated extreme ultraviolet lithography tools. ASML
has been banned from exporting its tools to China.

OCTANE (GITHUB REPO) [8]
Octane is a React replacement UI library with improved developer
ergonomics. It is incredibly efficient and is designed to stay close
to the speed of hand-written DOM code. Developers write with the React
API they already know, and Octane's compiler removes the virtual DOM,
Suspense waterfalls, rules-of-hooks bookkeeping, and hand-maintained
dependency arrays before the app ships.
SEAL (GITHUB REPO) [9]
Seal is an open standard for proving any file is real. It creates
sealed artifacts that can be verified by anyone. A seal proves
integrity, time, and the issuing certificate. Seals are anchored to a
public ledger that can be checked by anyone, forever.

actually selling Peacock to YouTube. All of Peacock's content will be
included in YouTube Premium subscriptions in the US starting early

NVIDIA BETS ON ILYA SUTSKEVER'S NEW AI LAB TO EXPAND COMPUTE REACH (3
MINUTE READ) [11]
Nvidia has made a substantial investment into Safe Superintelligence,
a company started by former OpenAI Chief Scientist Ilya Sutskever. The investment is part of a long-term partnership and will involve Safe Superintelligence receiving access to large amounts of Nvidia's
flagship GPUs. Safe Superintelligence had previously been relying
primarily on chips made by Google. Nvidia made the investment after
getting a rare glimpse into the state of the startup's research, which
has so far been kept secret.
