Trump Media approves $400 million stock buyback

U.S. President Donald Trump speaks to the media upon arrival at Joint Base Andrews following a visit to North Carolina, in Maryland, U.S., June 10, 2025. Trump Media & Technology Group , the parent company of Truth Social, Truth+, and the fintech platform Truth.Fi, said Monday its board has approved a stock buyback of up to $400 million. Trump Media stock rose about 3% on the news premarket. The Florida-based company, which trades under the ticker DJT on both Nasdaq and NYSE Texas, said the b

Death Stranding 2 is much more approachable, if you’re prepared

It took me a long time to appreciate Death Stranding. I’m not even sure I fully got it after my initial playthrough, which was equal parts mesmerizing and dull. The game, in which you play as a postapocalyptic delivery man in a world ravaged by a breach with the afterlife, demands a lot from players. The gameplay is fiddly and frustrating, and the storyline is often inscrutable, at times seeming to make no sense. While it borrows elements from walking sims and stealth games, there’s nothing like

Death Stranding 2 Review: Still Weird, but Way More Playable

When Death Stranding came out in 2019, I did what a lot of people apparently did: Played it for an hour, thought it was a bit weird, and didn't pick it up again until years later (in my case, 2022). So when a sequel to the game was announced, I wondered what Hideo Kojima could possibly do in a follow-up to his strangest game yet. After playing Death Stranding 2 for 40-plus hours, he did quite a bit. Death Stranding 2: On the Beach should have been called Death Stranding 2: Quality of Life, beca

Kids' Smartwatches Might Be Better Phone Alternatives: Here's What to Look For

A big advantage of giving a child a smartwatch is that it saves you from having to buy a smartphone while still providing a direct line to your kid. This can be especially helpful for parents managing pickup and drop-off logistics or relying on other caregivers for transportation. Younger kids, in particular, may benefit from avoiding the distractions that come with a phone. The fact that a watch is strapped to their wrist is also a bonus, considering how many water bottles and sweatshirts end u

Book review: Surveillance & privacy

Means of Control: How the Hidden Alliance of Tech and Government Is Creating a New American Surveillance State Byron Tau CROWN, 2024 Midway through his book, Tau, an investigative journalist, recalls meeting with a disgruntled former employee of a data broker—a shady company that collects, bundles, and sells your personal data to other (often shadier) third parties, including the government. This ex-employee had managed to make off with several gigabytes of location data representing the preci

Cataphract: Medieval-fantasy roleplaying wargame, in the Black-Sea C. 1300

Cataphracts Design Diary #1 Cataphracts commanders: there is no actionable intelligence in this post. Read on. About two months ago, I reread several series on military historian Bret Devereaux’s blog, ACOUP: analyses of Helm’s Deep and Minas Tirith, breakdowns of pre-modern command and pre-modern logistics, and, of course, a post simply titled “How Fast Do Armies Move?”. I’m a fan of Devereaux’s—he writes in that delicious space of really knowing his history yet also with the understanding he

Taiwan Is Rushing to Make Its Own Drones Before It's Too Late

In the span of just a few years, drones have become instrumental in warfare. Conflicts in Ukraine, Iran, Nagorno-Karabakh, Sudan, and elsewhere have shown how autonomous vehicles have become a quintessential part of modern combat. It’s a fact that Taiwan knows all too well. The island nation, fearing imminent invasion from China, has both the need, know-how, and industry necessary to build a robust and advanced drone program. Yet Taiwan, which has set an ambitious target of producing 180,000 d

Best Internet Providers in Anaheim, California

What is the best internet provider in Anaheim? AT&T Fiber is CNET's top pick for the best internet service provider in Anaheim. The internet service provider is the best option for most households in the city because of its fast, symmetrical speeds that come with straightforward plan terms and reasonable pricing. Not every address in Anaheim is served by AT&T Fiber. For those outside the coverage area, options like Spectrum or T-Mobile Home Internet are also solid picks, depending on what’s ava

Trump Mobile promise telehealth and roadside perks, but is it worth the cost?

From businessman to politician, and now to wireless service provider? Coming way out of left field, it seems the Trump Organization is now looking to leverage the Trump name to bring phone service to its fan base. According to the Trump Organization, the company won’t directly operate Trump Mobile and is instead licensing the rights to an unnamed third party. Trump Mobile will offer just one plan, dubbed the 47 Plan, as a not-so-subtle nod to Trump’s current presidential term. The company will

How fast are Linux pipes anyway?

2022-06-01 How fast are Linux pipes anyway? The challenge, and a slow first version # First of all, let’s start with measuring the performance of the fabled FizzBuzz program, following the rules laid down by the StackOverflow post: % ./fizzbuzz | pv >/dev/null 422GiB 0:00:16 [36.2GiB/s] pv is “pipe viewer”, a handy utility to measure the throughput of data flowing through a pipe.

Low-Temperature Additive Manufacturing of Glass

Researchers used the low-temperature additive manufacturing process to build the glass cups above. The optical behavior of the printed cups can be tailored by altering the chemical components of the inks. Additive manufacturing (3D printing) holds promise for fabricating complex glass structures that would be unattainable with traditional glass manufacturing techniques. Lincoln Laboratory’s innovative approach allows additive manufacturing of multimaterial glass items without the need for costl

‘Tron: Ares’ is Disney’s Big Hall H Movie for San Diego Comic-Con

Marvel may be skipping San Diego Comic-Con’s famous Hall H panel this year, but Disney’s reportedly got Tron: Ares showing up in its stead. According to TheWrap, the sci-fi sequel will get a panel during the annual pop culture convention. That would be noteworthy on its own, but it takes on further significance owing to its lead star, Jared Leto, who plays the titular Ares program. In early June, AirMail published a report wherein multiple women accused the Morbius and House of Gucci actor of i

Weird-shaped notebooks make me want to write again

Andru Marino is an audio and video producer at The Verge. “I make videos on our YouTube / TikTok / Instagram channels, and have produced our podcasts like Vergecast, Decoder, and Why’d You Push That Button?” He also keeps a lot of notes, and his latest favorite places to keep them are the Triangle and Sidekick notebooks.

Google killed Maps Timeline, so I self-hosted a better one

Dhruv Bhutani / Android Authority As an avid traveler, Google Maps Timeline has long been one of my favorite hidden features. I’m used to opening it on slow Sunday afternoons and wandering through my own travel history. It showed alleyways I had forgotten, long layovers that blurred together while stepping out for a quick brunch across a new city, and impulsive last-minute rail journeys across Eastern Europe that never made it into photos. It’s always felt like a private travel diary logging ev

When is the best time to book your flight? Google just revealed its airfare secrets

Alexander Spatari/Getty Images The last time I booked a vacation flight, I literally spent over an hour finding the cheapest ticket to Hawaii with two criteria in mind: that it wasn't a red-eye flight, and it only had one layover. At least one layover was to be expected (at LAX) because Kentucky is a long way from the Aloha State. I could've saved some time, though -- and money -- had I known what Google's recent report revealed. Also: 7 gadgets I recommend for travel as a digital nomad What

Tell HN: Beware confidentiality agreements that act as lifetime non competes

Just a note of warning from personal experience. Companies don’t really need non-competes anymore. Some companies take an extremely broad interpretation of IP confidentiality, where they consider doing any work in the industry during your lifetime an inevitable confidentiality violation. They argue it would be impossible for you to work elsewhere in this industry during your entire career without violating confidentiality with the technical and business instincts you bring to that domain.

I Was Overwhelmed by Mattress Shopping. This $374 Mattress Topper Bought Me a Few More Comfortable Years

CNET's key takeaways The ErgoAlign Mattress Topper from Helix normally costs $499 but it's on sale right now for $374 for the queen and $328 for the full size. It's a comfortable, band-aid solution until my next big mattress purchase. But it's pricier than other mattress toppers. The Nest Bedding Cooling Topper is $100 less, for example.

How does a phone with a crazy external lens compare to the S23 Ultra’s zoom camera?

Hadlee Simons / Android Authority The vivo X200 Ultra is a great camera phone in its own right (if you’re willing to import it), in no small part due to its impressive 200MP 3.7x periscope camera. However, the company switches things up by offering an optional external lens for even better zoom. The X200 Ultra’s 2.35x telephoto converter lens effectively turns the phone’s 200MP periscope camera into an ~8.6x shooter. I thought it would be a good idea to compare this lens to the Galaxy S23 Ultr
