Nvidia beats Apple to a $4T valuation as it rides AI wave

Samsung Galaxy Z Flip 7 hands-on: Bigger screens, bigger battery, better foldable?

Once again, it’s time for Samsung’s mid-year Galaxy foldable showcase. Over the last 10 years, Samsung gave us curved edges, curved screens, and then screens that fold (both ways). While we’re still waiting for that rumored tri-fold Galaxy, Samsung has primed two new Flip foldables, the Galaxy Z Flip 7 and (surprise!) the Z Flip 7 FE. First, there’s the Galaxy Z Flip 7. This year, the biggest change is a larger 4.1-inch second display with cutouts for the dual cameras. This occupies the entire

Moroccan founder raises $4.2M for her YC-backed startup building the next layer of AI search

As generative AI reshapes industries, one of its most important yet invisible challenges is retrieval, the process of fetching the right data with relevant context from messy knowledge bases. Large language models (LLMs) are only as accurate as the information they can retrieve. That’s where ZeroEntropy wants to make its mark. The San Francisco-based startup, co-founded by CEO Ghita Houir Alami and CTO Nicolas Pipitone, has raised $4.2 million in seed funding to help models retrieve relevant da

HBO Max comes full circle, and this time your apps will auto-update

The HBO streaming video app became HBO Max when the company added Warner Bros movies and Turner TV shows. In the worst rebrand since Twitter became X, the company later dropped the unique and valuable HBO part of the name and kept the generic and worthless Max part. Two years later, the company is fixing that. It today becomes HBO Max once more – and this time around, your apps should automatically update … Musk still holds the dumbest rebrand award thanks to throwing away a global household n

HBO Max is back, HBO Max says

After revealing back in May that it would change the name of its Max streaming service back to HBO Max sometime this summer, Warner Bros. Discovery (WBD) is starting to do that as of Wednesday.

Show HN: Dev atrophy test – Can you still code without AI?

Hey HN, I'm Per from Scrimba (YC S20), the code-learning platform. There's been a lot of talk lately about whether AI tools are causing skill atrophy amongst developers. We get a front-row seat to this, and we see more and more students struggle with basic concepts, and building apps on their own. This is almost always a consequence of relying too much on ChatGPT and vibe coding tools. So we built a small side project: https://devatrophy.com It's a test of your core web dev knowledge — no ha

Introduction to Indian English

Content In less than 200 years since its formal introduction as part of a nascent and westernized education system, English has grown to be the medium through which the people of India communicate with the world, and often with one another. In large parts of a country with several major languages, it vies with Hindi—the most commonly used Indian language—as the spoken language of choice. There is a range of ability from a mere smattering of words, to some amount of rudimentary communication, to

Product of Additive Inverses

Product of Additive Inverses By Susam Pal on 29 May 2025 A negative number multiplied by another negative number results in a positive number.

In this article, we will prove this rule, not just for numbers but for any algebraic structure that, in a general sense, behaves somewhat like numbers. Contents Illustration Let u
