'Absolute miracle' breakthrough provides recipe for zero-carbon cement (3 minute read)

Old concrete can be recycled in steel-processing furnaces to purify iron, producing 'reactivated cement' as a byproduct. The process produces completely carbon-zero cement if renewable energy is used. The resulting concrete has similar performance to the original material. The technique doesn't add major costs to either concrete or steel production and it significantly reduces CO2 emissions compared to the usual methods of making both. Industrial-scale trials of the technology are set to begin soon.

SpaceX sets date for next Starship flight, explains what went wrong the last time (3 minute read)

SpaceX is targeting June 5 for its next Starship test flight. The highly anticipated flight seeks to demonstrate the Super Heavy stage's ability to make a soft landing in the Gulf of Mexico. It also aims for the Starship upper stage to make a controlled reentry through the Earth's atmosphere before falling into the Indian Ocean. The Super Heavy first stage failed to make a soft landing in previous attempts due to a blockage in a filter in the Raptor engines. The Starship upper stage lost the ability to control its altitude during its coast phase in space due to clogged valves used by its reaction control thrusters.

Why you shouldn't use AI to write your tests (7 minute read)

Tests are not always valuable - tests written by AI are even less valuable because the tests are derived from the code and they aren't written with intent. AI may be able to write higher-level tests that focus on feature coverage. It may also be useful for writing AI tests to fuzz apps, translating acceptance criteria into tests, and writing code that fits tests.

Where are the builders? (12 minute read)

There are now fewer entrepreneurs in their 20s on a path to outlier success than there were in previous decades. This could be because their attention is being taken up by things like games and TikTok, or they may have so little free time they no longer have original ideas. The tech industry could be getting too good at consumer app optimization, which may be producing undesirable outcomes when paired with adoption at a enough age.

Amazon cloud boss Matt Garman inherits business under pressure to keep pace in AI (13 minute read)

Matt Garman, a veteran AWS executive who most recently led sales and marketing, is now taking the helm at the cloud services provider. Amazon has yet to emerge as a leader in generative AI despite throwing billions of dollars behind Anthropic and rolling out its own large language models. Growth at AWS also decelerated to 13% in 2023, reflecting more conservative spending by businesses on IT and cloud services. While the company remains the leader in cloud infrastructure, Microsoft is quickly closing the gap.
