Meet Macroscope: an AI tool for understanding your code base, fixing bugs

techcrunch.com Sarah Perez 2025-09-19 01:52:16

The founders who previously sold their livestreaming video startup Periscope to Twitter are back with a new startup — and no surprise, it’s an AI-focused company this time around. On Wednesday, former Twitter head of product Kayvon Beykpour announced the launch of Macroscope, an AI system aimed at developers and product leaders that summarizes updates to a codebase and catches bugs, among other things. The startup was co-founded by Beykpour, now Macroscope CEO, in July 2023, along with childho

Ten years after selling Periscope to Twitter, startup's co-founder raises $40 million for Macroscope

cnbc.com Jordan Novet 2025-09-19 13:00:01

It's been a decade since Kayvon Beykpour sold Periscope to Twitter for a reported $100 million, allowing the social media site to jump into livestreaming. Twitter shuttered Periscope in 2021, and the parent company, now called X and owned by Elon Musk, gravitated to a live events product called Spaces. Meanwhile, Beykpour, who spent seven years at Twitter after the acquisition, is back with Macroscope. He said on Wednesday that he's raised $40 million from venture investors, including GV (form

This smartphone telescope brought tears to my eyes with stunning photos - how it works

Vaonis Hestia ZDNET's key takeaways The Vaonis Hestia is a smartphone telescope device that retails for $300. The Hestia does well at capturing detailed photos of planets and the stars, and an intuitive app helps guide you. It is an expensive device that takes some getting used to, and the better smartphone camera you have, the better quality photos you will get. $299 at B&H Photo-Video Amidst all the doomscrolling, TV binging, and overworking, we've forgotten to look up at the sky every once

Close the loop: analytics that teach your chatbot to fix itself

Many chatbots stall for the same reason. Unanswered questions build up and nothing changes. Teams ship a release and move on. Users try again and give up. The way out is simple. Treat every miss as a signal. Capture it in a standard way. Decide whether it was noise or a real gap. Turn real gaps into small updates in guardrails or knowledge. Run that loop every week.

Full Moon: Seestar S50 vs. Samsung S25

news.ycombinator.com Nikolaos Papadopoulos 2025-09-23 17:31:49

The full moon is one of those sights that almost begs to be photographed, no matter what camera you’re using. Most of the time, that means a smartphone, and to be fair, modern phones are excellent at handling bright subjects like the moon. Of course, a telescope should reveal far more than a phone camera, but I wanted to see just how big that difference really is. So last night, under clear skies, I took two photos.

Scientists Boast That Their AI-Powered Stethoscope Only Fails Two-Thirds of the Time

futurism.com Unknown 2025-10-06 04:00:25

A team of researchers in the UK say their AI-powered stethoscope can detect three different heart conditions in just 15 seconds. It's also, they readily admit, horrendously inaccurate. Placed over the chest, the "smart" gizmo analyzes the rhythms of the heartbeat and blood flow that're undetectable to the human ear, while also performing a quick electrocardiogram, or ECG, which is a test that gauges your heart's electrical activity. Then, all that info is packaged and sent "securely" to the c

Galileo’s telescopes: Seeing is believing (2010)

news.ycombinator.com Unknown 2025-11-15 11:33:43

Four hundred years ago, Galileo Galilei (1564-1642) was in a state of anxiety. In January, he had discovered four moons orbiting Jupiter. In March, he had published this and other remarkable discoveries made with his improved telescope in Sidereus Nuncius (‘The Starry Messenger’). But by the summer, he was becoming profoundly alarmed. He had offered philosophers and mathematicians in Venice, Padua, Florence, Pisa and Bologna the chance to look through his telescope and confirm his discoveries. S

We keep reinventing CSS, but styling was never the problem

We Keep Reinventing CSS, but Styling Was Never the Problem We’ve been building for the web for decades. CSS has had time to grow up, and in many ways, it has. We’ve got scoped styles, design tokens, cascade layers, even utility-first frameworks that promise to eliminate bikeshedding entirely. And yet, somehow, every new project still begins with a shrug and the same old question: “So… how are we styling things this time?” It’s not that we lack options.

The U.S. Could Lose a Crucial Futuristic Telescope to Spain if Trump’s Budget Passes

gizmodo.com Ellyn Lapointe 2025-12-17 08:40:22

Spain has offered to spend up to €400 million ($471 million) to host the Thirty Meter Telescope, an enormous observatory project facing imminent cancellation due to U.S. budget constraints. If Spain strikes a deal, the TMT would be built on La Palma in the Canary Islands rather than on Mauna Kea, a mountain in Hawaii. In 2016, La Palma became the backup location for the observatory in case the primary site in Hawaii didn’t work out as an option, according to the TMT International Observatory. N

James Webb Spots Planets Forming Into Solar System in Real Time, Like an Organism's First Cells

Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would've formed some 4.6 billion years ago. The findings, published as a study in the journal Nature, are the first time we're seeing such an early stage of planets being formed anywhere in the cosmos. "We've captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,"

Getting a piece of electronics to run doom (1993) is a classic project in hobby electronics, and so far people have gotten doom to run on pretty much anything, including analog oscilloscopes. However, in all cases that I have seen, the only part of the oscilloscope that is really "running" doom is the CRT display, which is hooked directly to an external computer a la 90's game consoles.Meanwhile, people also have managed to get analog oscilloscopes to display some pretty extraordinary and dynami

NASA’S James Webb Space Telescope has captured its first direct image of an exoplanet

NASA’S James Webb Space Telescope has captured direct images of a planet outside of our solar system, which is the first time it has accomplished such a feat. This is a very big deal because exoplanets don't put out much light, so researchers typically discover new planets through indirect methods like keeping track of shadows as they pass across a host star. Webb, however, didn't have to do all that. It has directly captured images of a planet called TWA 7 b . Scientists believe the planet is

Perched atop the Cerro Pachón mountain in Chile, 8,684 feet high in the Atacama Desert, where the dry air creates some of the best conditions in the world to view the night sky, a new telescope unlike anything built before has begun its survey of the cosmos. The Vera C.
