Jack Dorsey working on Bluetooth messaging app, Bitchat

Block CEO and Twitter co-founder Jack Dorsey wrote in an X post on Sunday night that he spent his weekend creating an app called Bitchat (presumably a combination of the words “bit” and “chat,” and not the other combination of words that it looks like). Bitchat is a messaging app that operates through Bluetooth mesh networks, allowing users to send messages without Wi-Fi or cell reception. Because of Bluetooth’s technical limitations, this kind of app generally only works at a range of around 1

Bluesky users can customize their notifications, including activity alerts from their favorite accounts

On Monday, Bluesky announced three updates to enhance notifications, allowing users to personalize their experience while decluttering their notification center and reducing unnecessary alerts. The updates include the ability to receive activity notifications for specific accounts, as well as options to adjust notification preferences to control which alerts you receive.

I'm not losing sleep over Elon Musk's political ambitions

Just a month after his explosive fallout with Donald Trump, Elon Musk is floating the idea of forming his own political party. In a poll on X, 1.24 million of his followers voted, with 65.4 percent saying they would like to see such a thing happen. The America Party would offer “independence” from a political system Musk says is too focused on “waste & graft.” Like so many things Musk says, it’s not worth paying too much attention to unless he puts his money where his mouth is. But, also like so

How Meta's new AI chatbot could strike up a conversation with you

Andriy Onufriyenko/Getty Images Despite a major usage and monetization gap, Meta, like many AI companies, is going all in on AI chatbots -- even giving them the ability to strike up a conversation with you, unprompted. According to a report from Business Insider published last week, leaked documents indicate the company is now building AI chatbots that proactively initiate conversations with users. The new feature is intended to boost user engagement and retention at a time when many leading t

New sphere-packing record stems from an unexpected source

The advantage of Rogers’ method was that you didn’t have to start with a particularly efficient lattice to get an efficient sphere packing. You just had to choose the right ellipsoid. But this introduced a new complication. Unlike a sphere, which is completely defined by a single number — its radius — an ellipsoid is defined by several axes of different lengths. The higher the dimension, the greater the number of directions you can stretch your ellipsoid in, and the more options you have for wha

The Chinese EV Carmaker That Is Quietly Crushing Tesla

While Tesla’s struggles dominate the headlines, a quieter but more significant story is unfolding: Chinese electric vehicle makers are on a tear. For the second consecutive quarter, Elon Musk’s Tesla has seen its sales decline, a stark contrast to the booming growth reported by rivals like BYD and NIO Inc, who are steadily gaining market share and widening their lead. The second-quarter sales numbers paint a bleak picture for the American EV pioneer. Tesla delivered 384,122 vehicles worldwide,

‘Killer Bee’ Swarm Spotted Near Georgia, Raising Alarms

A small county in Georgia may be facing a “killer bee” invasion. The Africanized bee is the common honeybee’s aggressive, lethal cousin. They look just like honeybees, but this hybrid between European and African honeybees is infamous among beekeepers for ganging up and attacking intruders—bee or human—earning them the nickname “killer bee.” Africanized bees arrived on U.S. soil in the 1990s and have since been spotted across parts of the southern U.S. But this latest sighting of so-called kil

Starlink’s In-Flight Wi-Fi Is Faster Than Its Home Internet Speeds: Here’s Why

Starlink is nearly twice as fast as any other in-flight Wi-Fi option, according to the latest report by the speed test site Ookla. (Disclaimer: Ookla is owned by the same parent company as CNET, Ziff Davis.) The satellite internet company from SpaceX clocked median download speeds of 152 megabits per second and upload speeds of 24Mbps. That means that Starlink’s speeds in the air are faster than some internet providers on the ground. Those download and upload speeds were nearly twice as fast a

Trump and Congress finalize law that could hurt your Wi-Fi

The Federal Communications Commission has regained its authority to hold spectrum auctions and could use that power to take spectrum away from Wi-Fi networks and license it to mobile carriers AT&T, Verizon, and T-Mobile. As we previously wrote, the Senate budget bill pitched by Ted Cruz (R-Texas) called for at least 800 MHz to be auctioned and allowed part of it to be taken from the 6 GHz band that's being used to boost speeds in the new generation of Wi-Fi networks. The House previously voted

'Batavia' Windows spyware campaign targets dozens of Russian orgs

A previously undocumented spyware called ‘Batavia’ has been targeting large industrial enterprises in Russia in a phishing email campaign that uses contract-related lures. The researchers believe the operation has been active since at least last year in July and is ongoing. Based on telemetry data, the phishing emails delivering Batavia have reached employees at several dozen Russian organizations have been targeted. Since January 2025, the campaign has increased in intensity and peaked toward

Dyson, techno-centric design and social consumption

7th July 2025 As a design engineer I’ve spent plenty of time mulling over what ‘good’ design is. The question is complex and is a starting point for reflecting on our role as designers, how design should interact with society and what even constitutes design! I recently visited the Glasgow Zine Festival and picked up a wee zine about one man’s hatred of James Dyson, which has inspired me to put some of my own thoughts on the topic down in words. I'm going to focus on formal design elements but

Tesla Is Losing the EV War to Chinese Carmakers

Apple’s newest AI study unlocks street navigation for blind users

There’s no shortage of rumors about Apple’s plans to release camera-equipped wearables. And while it’s easy to get fatigued by yet another wave of upcoming AI-powered hardware, one powerful use case often gets lost in the shuffle: accessibility. SceneScout, a new research prototype from Apple and Columbia University, isn’t a wearable. Yet. But it hints at what AI could eventually unlock for blind and low-vision users. As Apple’s and Columbia University’s researchers explain it: People who are

Solving Wordle with uv's dependency resolver

Introduction In a previous life, I wrote a Sudoku solver that relied on Poetry's dependency resolver. We ended up selling that startup to EDB (not because of the Poetry hack), which means that they now own this IP. And, since then, Python packaging has advanced, with uv taking the world by storm. This means that it's time for a refresh. Can we use uv instead of Poetry? And can we solve a Wordle instead of a Sudoku? For the impatient: you can get the solver from my GitHub. Run uv run main.py r

President Donald Trump recently extended a deadline for the owner to sell off i

F1 in Britain: Terrible English summer weather equals entertaining race

The heat dome that has been oppressing much of Europe seems to have largely ignored the British Isles. Not a drop of rain marred the 24 hour races at Le Mans, the Nürburgring, or Spa-Francorchamps, held unusually over consecutive weekends this June. Similarly, last weekend's Austrian Grand Prix took place under scorching skies that were baking the Tyrolean mountains. No such luck for the vast crowds at Silverstone attending the British Grand Prix this past weekend, who definitely needed their wa

Apple appeals 500 million euro EU fine over App Store policies

Two young men stand inside a shopping mall in front of a large illuminated Apple logo seen through a window in Chongqing, China, on June 4, 2025. Apple on Monday appealed what it called an "unprecedented" 500 million euro ($586 million) fine issued by the European Union for violating the bloc's Digital Markets Act. "As our appeal will show, the EC [European Commission] is mandating how we run our store and forcing business terms which are confusing for developers and bad for users," the compan

When Figma starts designing us

I first encountered Figma in 2013, when Dylan Field demoed an early prototype to me at O’Reilly’s Foo Camp. I remember the pen tool feeling surprisingly elegant, but I missed the bigger picture: the radical implications of a design tool that ran in the browser. A decade later, Figma is a core part of our creative process, and without it, we wouldn't have been able to build a fully remote design practice. That’s probably why Dylan is a near-billionaire and I’m not. However, over the course of th

Apple appeals EU’s €500M fine over App Store payment restraints

In Brief Apple on Monday filed an appeal against the EU’s decision to fine the company €500 million (about $580 million) for not complying with rules that mandate companies to let developers steer users outside the App Store for making purchases, according to multiple reports. The European Commission issued the fine in April, saying that Apple failed to comply with the Digital Markets Act (DMA) rules to allow developers to accept payments for their apps outside Apple’s ecosystem.
