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.

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.

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.

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.

It's that "oh, S—!" moment.

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.

The two standard approaches for counting the unique values in a large array of mostly-unique uint64s are to insert into a hash table and return the number of entries, or to sort the array, then count positions that differ from their predecessor. Sorting is typically faster than hash tables in a well-tuned implementation. This problem and its variants are the inner loop of some of the world's biggest CPU workloads. This article takes a look at why sorting wins, when one should choose hash tables versus a sort, and why it matters.

The even equity vesting schedule is quickly becoming a thing of the past. Many companies are now shifting to front-loaded vesting. This shift is a philosophical pivot toward a more dynamic, performance-driven compensation strategy. Top performing employees stand to benefit, while others will have more uncertainty of compensation in subsequent years.

Google launched Chrome in the fall of 2008. The project has grown from a secret skunkworks into a browser used by billions. Chrome turns 17 this week. This post walks through Chrome's origins and evolution across speed, security, stability, and simplicity, and highlights key milestones. The journey has been one driven by relentless performance improvements, cutting-edge security efforts, and an uncompromising focus on user experience.
