Voi CEO says he’s open to acquiring Bolt’s micromobility business

Shared micromobility startup Voi is on the hunt for acquisitions. And on CEO Frederik Hjelm’s wishlist is Bolt, the European mobility super-app best known for ride-hailing. Not that Bolt’s micromobility business is necessarily for sale — despite talk of Voi buying the company’s scooter and bike arm. Bolt declined to comment when TechCrunch reached out. “Bolt is a great company, but they are mainly a ride-hailing company,” Hjelm told TechCrunch on stage at the Micromobility Industries roundtabl

Internet collapses across Iran, say web-monitoring firms

Internet connectivity in Iran almost completely disappeared on Wednesday, according to web-monitoring firms, as war with Israel enters its sixth day. NetBlocks, a firm that tracks internet access across the world, wrote on X that Iran is “now in the midst of a near-total national internet blackout.” The firm’s assessment was confirmed by other internet-monitoring organizations. Data collected by IODA, which is a system that “monitors the Internet infrastructure connectivity in near-real time,

Police shut down Cluely’s party, the ‘cheat at everything’ startup

The latest San Francisco startup culture drama happened on Monday night. And it centered around “the most legendary party that never happened,” Cluely founder and CEO Roy Lee tells TechCrunch. Cluely had hoped to throw an after-party for a Y Combinator event occurring on Monday and Tuesday called AI Startup School. The event drew crowds thanks to scheduled speakers like Sam Altman, Satya Nadella, and Elon Musk. Cluely is an AI startup born of controversy and rage-bait comedy marketing. True to

How Disney is using Unreal Engine 5 to add major upgrades to Millennium Falcon: Smugglers Run

Millennium Falcon: Smugglers Run was a landmark moment for Walt Disney Imagineering when it opened in 2019. It was the first Disney ride that allowed guests to directly control their experience and interact with the story. But for the next Smugglers Run mission, the company is going one step further and making the ride feel a lot more like a traditional video game, complete with branching choices and sophisticated enemies. WDI worked closely with visual effects studio Industrial Light & Magic (

Did Samsung's fitness coach just outpace Apple's Workout Buddy?

Health wearables are leaning into AI-powered health coaches and advisors, which can use all the health and fitness data they aggregate to deliver actionable insights or help the user achieve a fitness goal. Last week, Apple debuted a new AI-powered WatchOS 26 feature that will be available on Apple Watches in the coming months. Workout Buddy is the smartwatch's health coach, guiding wearers through a workout and providing historical stats, encouragement, and more. Also: Your Galaxy Watch is ge

The magic of through running

This is the lead story of the new issue of Works in Progress, Issue 19. Read the full issue, including stories on how to redraw cities and the secret history of inflation targeting, on our website. In the nineteenth century, the societies of Europe and North America were profoundly transformed by the vast railway networks they built. When these railway networks entered cities, however, they faced a crucial problem: they had to stop. Rather than carrying on through the city, it was common for th

Spotify’s Daniel Ek just bet bigger on Helsing, Europe’s defense tech darling

When Daniel Ek isn’t busy running Spotify or building his new AI-driven health tech enterprise, he’s making massive bets on the future of European warfare, seemingly. The billionaire, who primarily lives in Stockholm, just led a €600 million investment in Helsing, a four-year-old, Munich-based defense tech company that is now valued at €12 billion, as first reported by the Financial Times and confirmed separately by TechCrunch. The deal makes it one of Europe’s most valuable privately held comp

The US Navy is more aggressively telling startups, ‘We want you’

While Silicon Valley executives like those from Palantir, Meta, and OpenAI are grabbing headlines for trading their Brunello Cucinelli vests for Army Reserve uniforms, a quieter transformation has been underway in the U.S. Navy. How so? Well, the Navy’s chief technology officer, Justin Fanelli, says he has spent the last two and a half years cutting through the red tape and shrinking the protracted procurement cycles that once made working with the military a nightmare for startups.

As grocery shortages persist, UNFI says it’s recovering from cyberattack

UNFI said in an update on Sunday that it was restoring its electronic ordering systems, which its customers use to place orders for their grocery stores and supermarkets. The company, which provides more than 30,000 stores across the U

Show HN: Seastar – Build and dependency manager for C/C++ with Cargo's features

Seastar Seastar is a fast, extensible build system for C, C++, and maybe soon, Rust and Zig as well. I believe that it should be easy to make, prototype, and iterate upon designs. While C is still one of our most widely used languages, it makes it hard to create programs easily, especially for beginners. Instead, Seastar aims to be more like Rust's tooling with cargo , but supporting seamless compilation across more languages. Running Seastar is very simple to build and run. Assuming you have

How fast can the RPython GC allocate?

While working on a paper about allocation profiling in VMProf I got curious about how quickly the RPython GC can allocate an object. I wrote a small RPython benchmark program to get an idea of the order of magnitude. The basic idea is to just allocate an instance in a tight loop: class A ( object ): pass def run ( loops ): # preliminary idea, see below for i in range ( loops ): a = A () a . i = i The RPython type inference will find out that instances of A have a single i field, which is an i

I tested this affordable Garmin sports watch, and it shouldn't be this good for the price

ZDNET's key takeaways The Garmin Forerunner 165 is typically available for $249, with the Music model priced at $299. The watch is small and lightweight, has a vibrant AMOLED display, 19 hours of GPS battery life, and features extensive support for running. I just wish there were more sports modes. $199.99 at Garmin $191.99 at Amazon $199.99 at Crutchfield more buying choices For a limited time, Amazon has discounted the Garmin Forerunner 165 down to just $191 ($59 off), making the already af

$100 Hamburger

Aviation slang $100 hamburger ("hundred-dollar hamburger") is aviation slang for the excuse a general aviation pilot might use to fly.[1][2] Background [ edit ] A $100 hamburger trip typically involves flying a short distance (less than two hours), eating at an airport restaurant, and then flying home. "$100" originally referred to the approximate cost of renting or operating a light general aviation aircraft, such as a Cessna 172, for the time it took to fly round-trip to a nearby airport. H

Clay secures a new round at a $3B valuation, sources say

Clay, a sales automation startup, has raised a Series C round at an approximate $3 billion valuation, led by Capital G, according to three sources with knowledge of the deal. Clay and Capital G didn’t respond to a request for comment. The new round comes just a month after the New York startup announced that it will allow most of its employees to sell some of their shares at a $1.5 billion valuation. That secondary deal, known as a tender offer, was led by Sequoia, which agreed to purchase up

The curse of Toumaï: an ancient skull and a bitter feud over humanity's origins

On a late-summer day in 2001, at the University of Poitiers in west-central France, the palaeontologist Michel Brunet summoned his colleagues into a classroom to examine an unusual skull. Brunet had just returned from Chad, and brought with him an extremely ancient cranium. It had been distorted by the aeons spent beneath what is now the Djurab desert; a crust of black mineral deposits left it looking charred and slightly malevolent. It sat on a table. “What is this thing?” Brunet wondered aloud

Google Cloud outage brings down a lot of the internet

Large swaths of the internet went down on Thursday, affecting a range of services, from global cloud platform Cloudflare to popular apps like Spotify. It appears that a Google Cloud outage is at the root of these other service disruptions. Google Cloud said it started investigating service issues affecting its customers at 11:46 a.m. PT. The company still does not have an ETA for when its services will be back online. “We are currently investigating a service disruption to some Google Cloud se
