MICROSOFT, OPENAI TRUCE CLEARS HURDLE IN PATH TO FOR-PROFIT CONVERSION

Microsoft and OpenAI have reached a deal to extend their partnership. The agreement could ease OpenAI's path toward changes into a for-profit corporation. The companies have not disclosed the terms of the new contract but said that the current agreement was nonbinding. The agreement is a tentative win for OpenAI, which needed Microsoft's approval for its non-profit plan before it could be formally shared with state regulators. OpenAI told its venture-capital investors it would complete the restructure by the end of the year or risk losing out on $19 billion in funding.

MICROSOFT, OPENAI TRUCE CLEARS HURDLE IN PATH TO FOR-PROFIT CONVERSION

Microsoft and OpenAI will extend their partnership. The move could help OpenAI move towards becoming a for-profit corporation. OpenAI plans to create a new for-profit company in which Microsoft and OpenAI will each initially receive a roughly 30% stake. The rest will go to employees and investors. It plans to keep the nonprofit's control over the new for-profit and endow it with a stake valued at more than $100 billion.

THINGS I WISH I KNEW BEFORE SWITCHING TO REACT NATIVE

Core React concepts like hooks, functional components, and state management carry over when transitioning from React to React Native. However, developers must adapt to using native components instead of HTML elements, JavaScript objects for styling instead of CSS, and React Navigation instead of React Router. The good news is that API handling with libraries like Axios and TanStack Query remains largely the same, and responsive design principles using Flexbox still apply.

NEW VMSCAPE ATTACK BREAKS GUEST-HOST ISOLATION ON AMD, INTEL CPUS

Researchers from ETH-Zurich have found a new attack that allows an attacker to leak cryptographic keys from an unmodified QEMU hypervisor process running on modern AMD or Intel CPUs. In the attack, a guest user can influence indirect branch prediction in a host user process to leak arbitrary memory at a rate of 32 bytes/second with a byte-level accuracy of 98.7%. AMD has released a security bulletin about the issue. Linux kernel developers have released patches to mitigate the problem.

BITCOIN HOLDS $114K AS CPI KEEPS SEPTEMBER RATE CUT IN PLAY

Bitcoin steadied near $114K after August CPI data matched expectations, reinforcing odds of a 25 bps Fed rate cut next week. Headline CPI rose 2.9% YoY, while core held at 3.1%, aligning with forecasts and supporting a dovish policy pivot. Analysts say BTC remains bullish if it can close above $113K-$113.5K, with ETF inflows strengthening and markets now pricing in up to three rate cuts before Q1 2026.

SAMSUNG TAKING MARKET SHARE FROM APPLE IN U.S. AS FOLDABLE PHONES GAIN MOMENTUM

Shipments from Samsung surged in the US in the second quarter while Apple's market share declined. Apple remains on top of the US smartphone market, but it is experiencing turbulence for the first time in well over a decade. Samsung's Galaxy and Z phone lineup has a massive span of devices that stretches from $650 up to $2,400, targeting customers at every single price point. Apple may release a folding phone next year - trying out new form factors offers Apple the opportunity to sell devices at higher prices.

EARLY EXPERIMENTS SHOW FAST-ACTING ANTIDOTE TARGETS CARBON MONOXIDE POISONING

A newly engineered protein therapy called RcoM-HBD-CCC has been shown to cling to carbon monoxide and expel the poison via the kidneys within minutes when given intravenously to mice. The protein quickly sponges up the toxin without binding to nitric oxide, a gas molecule that plays a key role in relaxing blood vessels. The protein was shown to cling to carbon monoxide in human blood in test tubes. It is unknown how the treatment will work in human bodies until it is tested, but human trials are still likely to be a few years away.

REALITY IS RUINING THE HUMANOID ROBOT HYPE

There are still many issues, such as battery life, reliability, and safety, that need to be solved before humanoid robots can scale. However, before that, it is important to consider whether it is worth the trouble to make a bipedal robot. We already have reliable, efficient, and cost-effective robots, just without legs. Safe and reliable humanoid robots have the potential to revolutionize the market at some point in the future, but it might not be worth the effort.

A/B TESTING CAN'T KEEP UP WITH AI

Evals are still a new practice for many product teams. A/B testing is no longer sufficient for AI product optimization because it's expensive to create variants. AI eliminates this constraint - it is now possible to have unlimited variants that automatically update periodically based on real-user feedback. The companies that evolve to think in evals will build products that improve faster than their competitors can run in a single A/B test.
