Launch HN: Leaping (YC W25) – Self-Improving Voice AI

Hey HN, I'm Arkadiy from Leaping AI ( https://leapingai.com ). Leaping lets you build voice AI agents in a multi-stage, graph-like format that makes testing and improvement much easier. By evaluating each stage of a call, we can trace errors and regressions to a particular stage. Then we autonomously vary the prompt for that stage and A/B test it, allowing agents to self-improve over time. You can talk to one of our bots directly at https://leapingai.com, and there’s a demo video at https://www

Graphical Linear Algebra

Applications are open for the ACT Applied Category Theory Research School 2018! And because arithmetic science and geometric science are connected, and support one another, the full knowledge of numbers cannot be presented without encountering some geometry, or without seeing that operating in this way on numbers is close to geometry; the method is full of many proofs and demonstrations that are made with geometric figures. Fibonacci, preface to Liber Abaci (first published 1202, 1228 manuscrip

YouTube’s ‘Trending’ section is about to disappear

We’ve begun a broad expedited deployment of the configuration change across all affected infrastructure. We expect most impacted users will experience relief w

The Webb Telescope captures a mesmerizing view of the Cat's Paw nebula

Feast your eyes on the most mesmerizing feline foot known to humankind. The James Webb Space Telescope (JWST) captured this image of the Cat's Paw nebula. The European Space Agency (ESA) shared the picture to honor the telescope's three years of service. The Cat's Paw nebula is part of the Scorpio constellation. (You know, the one that looks like a scorpion?) It floats about 4,000 light years away from us. That translates to 23.5 quintillion miles. Put another way, that's a billion miles times

Kissing Bugs Are Creeping Into Florida Homes—and They’re Carrying a Dangerous Parasite

People in Florida are having to worry about a unique disease-carrying insect known as the kissing bug.

Scientists from the University of Florida (UF) and Texas A&M University led the study, published Monday in PLOS Neglected Tropical Diseases. They collected samples of kissing bugs found inside people’s homes, finding that a third were infected with the parasite Trypa

Synology masters both ease and control with BeeStation and DiskStation

Synology is synonymous with NAS, or network-attached storage, and there’s good reason for that. The DiskStation line of products is reliable and robust with a great community that supports consumer and professional use cases. More recently, Synology has reached beyond traditional NAS solutions with BeeStation, a private and family cloud storage solution. I’ve recently been testing the BeeStation Plus, a somewhat less capable, but much more approachable, product, and the DiskStation DS925+, a tra

Large-scale DNA study maps 37,000 years of human disease history

A new study suggests that our ancestors’ close cohabitation with domesticated animals and large-scale migrations played a key role in the spread of infectious diseases. The team, led by Professor Eske Willerslev at the Universities of Cambridge and Copenhagen, recovered ancient DNA from 214 known human pathogens in prehistoric humans from Eurasia. They found that the earliest evidence of zoonotic diseases – illnesses transmitted from animals to humans, like COVID in recent times – dates back t

Samsung drops Snapdragon for the Galaxy Z Flip 7 — here’s why it makes sense

After months of speculation about the status of Samsung’s custom Exynos chip program, we finally have an answer — it’s alive and kicking inside the new Galaxy Z Flip 7. This includes customers in the US, who had previously only been treated to a modern Exynos chip in the Galaxy S24 FE. However, this choice leaves Samsung with two different chips inside its latest flagship foldable portfolio. The Exynos 2500 is in the Z Flip 7, but Qualcomm’s Snapdragon 8 Elite powers the Galaxy Z Fold 7. But wh

This is the easiest drone I've ever flown - and it's not even close

ZDNET's key takeaways The Hoverair X1 Pro Max stands out with an eye-catching, unconventional design that sets it apart from typical drones. One of its standout capabilities is 8K video recording, offering stunning resolution for high-quality footage. However, its battery life leaves much to be desired, limiting how long you can fly before needing a recharge. $699 at Amazon I'll admit: before testing the Hoverair X1 Pro Max, I definitely had trepidation about the device.

Mighty mitochondria: Cell powerhouses harnessed for healing

James McCully was in the lab extracting tiny structures called mitochondria from cells when researchers on his team rushed in. They’d been operating on a pig heart and couldn’t get it pumping normally again. McCully studies heart damage prevention at Boston Children’s Hospital and Harvard Medical School and was keenly interested in mitochondria. These power-producing organelles are particularly important for organs like the heart that have high energy needs. McCully had been wondering whether t

AI Is a Lousy Chef

After my sage plant struggled for years in a shadowy corner of my roof-deck planter garden, I moved it into the sunniest spot up there. Boy did that make a difference. It also meant I needed to figure out what to do with all the leaves it produced. As luck would have it, I was also trying out AI cooking platforms. That night, I plugged the prompt “recipe using brats and lots of sage” into an AI recipe generator and it gave me what it called “sage infused brats skillet with caramelized onions.”

How to clear your iPhone cache (and why it greatly improves the performance)

What is cache? Cache -- or browser cache -- is the temporary storage of website files. So, things like images, scripts, and cookies that your browser saves on your phone to make pages load faster the next time you visit. Also: Every iPhone model that can be updated to iOS 26 (and which ones don't support it) Over time, though, those files can add up, taking a large bite out of your device storage and slowing things down. That's why it's smart to clear your browser cache regularly. In this art

The jank programming language

The jank programming language jank is a general-purpose programming language which embraces the interactive, value-oriented nature of Clojure as well as the desire for native compilation and minimal runtimes. jank is strongly compatible with Clojure and considers itself a dialect of Clojure. Please note that jank is under heavy development; assume all features are planned or incomplete. Where jank differs from Clojure JVM is that its host is C++ on top of an LLVM-based JIT.

MLB will test its robot umpire system at the next All-Star Game

While human umpires will still make the first call at the All-Star Game on July 15, Major League Baseball plans to let teams use a robot umpire to challenge rulings, ESPN reports.

MLB is essentially porting over the ABS challenge system used during spring training for the upcoming All-Star Game in At
