OPENAI AND MICROSOFT REPORTEDLY RENEGOTIATING PARTNERSHIP TO ALLOW FOR POTENTIAL IPO

OpenAI and Microsoft are reworking their partnership to allow OpenAI to move forward with a restructuring plan to create a for-profit public benefit corporation controlled by its nonprofit parent. Microsoft may take a smaller equity stake in the new entity in exchange for extended access to OpenAI's technology beyond the previously agreed-upon 2030 cutoff. OpenAI plans to reduce the percentage of revenue it shares with Microsoft as part of the restructuring. It needs approval from Microsoft to proceed with its plan.

HOW CURSOR INDEXES CODEBASES FAST

Cursor, an AI IDE, uses Merkle trees to efficiently index codebases. The process involves chunking code into semantic pieces, creating a Merkle tree of hashes, and synchronizing it with Cursor's server to generate and store embeddings in a vector database. Merkle trees allow Cursor to quickly identify and update only the changed files, reducing bandwidth and processing time.

ASCENSION REVEALS PERSONAL DATA OF 437,329 PATIENTS EXPOSED IN CYBERATTACK

Ascension, the second-largest private healthcare system in the US, suffered a data breach that exposed the personal and health information of 437,329 patients through a former partner's compromise. In December 2024, the partner faced a security incident due to a vulnerability in third-party software, leading to the theft of sensitive data, including names, contact details, SSNs, and medical visit records. This marks Ascension's second major cybersecurity incident, following a Black Basta ransomware attack in May 2024, prompting the company to offer affected patients two years of free identity monitoring.

While Elizabeth Holmes is in prison for defrauding investors through Theranos, her partner, Billy Evans, plans to start his own blood testing company. Evans is trying to raise money for a blood-testing company with a machine that bears more than a passing resemblance to Theranos' infamous blood-testing machine. The company, Haemanthus, is still in stealth, and not much information is available about it. It aims to eventually raise more than $50 million. Haemanthus plans to first address the pet health care market before progressing to humans.

CHINA JUST MADE THE WORLD'S FASTEST TRANSISTOR AND IT IS NOT MADE OF SILICON

A group of scientists at Peking University has created what they claim is the world's fastest and most efficient transistor. Made with a slender sheet of lab-grown bismuth and a new architecture, the two-dimensional, silicon-free transistor represents a radical rethinking of what chips can be and how they can be made. Chinese firms have been blocked from buying the latest silicon chip-making equipment due to ongoing US-led export restrictions, forcing researchers to find solutions from fresh perspectives. The team is now working on scaling up production - they used existing fabrication platforms, so the barrier to mass production may not be as high as with other experimental technologies.

US MILITARY TAPS ROCKET LAB'S NEW NEUTRON LAUNCHER FOR ‘POINT TO POINT' CARGO TEST FLIGHT IN 2026

Rocket Lab and the US Air Force Research Laboratory have planned a launch and return-to-Earth mission for Rocket Lab's Neutron rocket no earlier than 2026. The flight will test Neutron's reentry capabilities and the rocket's viability for global point-to-point cargo transportation objectives. Rocket Lab plans to debut its partially reusable Neutron later in 2025. The company has been launching its 59-foot-tall Electron rocket since 2018 and has significantly increased its launch cadence over the past few years. Neutron will stand at 141 feet tall with a 23-foot diameter.

ASK HN: WHAT WILL TECH EMPLOYMENT LOOK LIKE IN 10 YEARS? (HACKER NEWS THREAD)

While the role of the coder will likely still exist in 10 years, it will probably look very different from what it is today. However, it is important to remember that there is still a lot of work to be done before large language models can even replace junior developers. The role of debugging will grow as models trained on previous errors and methods won't catch bugs. AI is just another technology that claims it will change the world - it hasn't taken over yet, and it might not, just like 3D printing didn't ruin manufacturing, blockchain didn't ruin finance, and the metaverse hasn't caused mass migrations away from cities.
