Google's new Android-powered Googlebooks laptops are intended to be

A ROCKET SUPPLY CRUNCH IS MAKING IT HARDER TO HITCH A RIDE TO SPACE
(7 MINUTE READ) [7]

Many rockets under development are behind schedule. Prices for many
missions are rising. SpaceX is winding down the Falcon 9 to focus on
its new Starship vehicle. The company has stopped selling missions
where several companies share space on a Falcon 9. Launch demand is
set to outstrip supply at least through the end of the decade.

(7 MINUTE READ) [8]

Agility Robotics is going public through a merger with Michael
Klein's Churchill Capital XI at a $2.5 billion pre-money valuation.
The company's robots are deployed in a few places today and can do
tasks such as moving totes, feeding lines, and tending machines. Its
Digit v5 robot will be out later this year. The new robot will be able
to work alongside humans rather than in a cage/workcell. It will also

JEV INTRODUCES A NEW SHAPE OF LLM--SYSTEM ONE, AKA DECISION MODELS
(5 MINUTE READ) [11]

Jev is a new category of model called 'System One models' that
accepts text inputs, but only returns floating point numbers
corresponding to categories, yes/no questions, ratings, and associated confidence scores. It is fast and really cheap - output is free, and
input is $0.042 per million tokens. The model was released just under
a week ago, but the amount of activity around it has been extremely
impressive.

A SUMMER OF AI OPTIMIZATION (5 MINUTE READ) [12]

Several open source projects recently started running faster due to
being optimized with the help of AI. The techniques used to optimize
these projects were well known. However, it is likely developers never
tried them because it would be too risky. AI has made it cheap to try
new ideas.

THE BUSINESS OF BUILDING GOD (13 MINUTE READ) [14]

It is extremely likely that AI will change employment, society,
culture, and the world. However, businesses built around it will
remain subject to ordinary constraints. We will soon have new superintelligences that can solve impossible problems and help with
new miracles. This will open up a lot of niches to fill.

AN UNDERCOVER GOOGLE ANALYST INFILTRATED A NOTORIOUS SUPPLY-CHAIN
HACKING GANG (13 MINUTE READ) [15]

The hacker group known as TeamPCP tainted hundreds of open-source
programs with its malware, stole developer accounts to perpetuate that
software supply-chain hacking, and released a Dune-themed worm to
automate the process. They ultimately breached more than a thousand
companies. During a key moment of the group's rampage, an undercover
researcher from Google infiltrated the group. This allowed Google to
monitor the hacking spree from the inside, warn targets, and help
disrupt TeamPCP's attempts to exploit victims.
