Show HN: EchoStream – A Local AI Agent That Lives on Your iPhone

Hi HN, I’ve been working on a project called EchoStream, and I’d love to share it with you. As an AI startup founder, the first thing I do every morning is open Hacker News. I look for what other founders are building, check out new GitHub projects, and explore new products. But I started noticing that it was taking me the whole morning just to get through it all. I began to wonder: could an AI help me read Hacker News more efficiently? Could it summarize everything so I can quickly scan thro

Before the Z Fold7 Launch, Amazon Clears Out Galaxy S25 Ultra Stock at a Ridiculous Price

In just a few weeks, Samsung is expected to announce its latest generation of foldable smartphones as it does every year. If past trends continue, we’ll likely see the Galaxy Z Flip 7 and Galaxy Z Fold 7 take center stage. And even as anticipation builds for those devices, the top-selling traditional flagship remains the Galaxy S25 Ultra which is also the most high-end Android phone available today. And now, Amazon is offering a new discount on the Galaxy S25 Ultra 256GB model available for $1,

Best Mattress Toppers for 2025, Tested by Our Sleep Experts

If you need more time before making your next big mattress decision or you're waiting on that next big sale event -- a mattress topper is a good temporary sleep solution. The right mattress topper can add comfort and enhance your sleep quality -- and for far less than the $1,000 a year many US adults said they'd spend on better rest, per a CNET’s sleep survey. CNET’s sleep experts have been testing mattresses and their toppers for years. We carefully evaluate firmness, feel, construction and wa

Ford Ranger Plug-In Hybrid Review: Prices, Availability, Specs

Fitness for purpose. Take a deftly aimed power tool to all the marketing flim-flam, and you can’t go far wrong with that mantra. There’s no messing around when it comes to a pick-up truck, a vehicle that has a clear job to do, and in most cases does it admirably. Except that even this segment isn’t immune to mission creep, and these hardy vehicles are now expected to double as workhorse and acceptable all-round family transport. The Ford F-150 may typify the breed, but outside of the US the Ran

Inside the courthouse reshaping the future of the internet

The future of the internet will be determined in one building in Washington, DC — and for six weeks, I watched it unfold. For much of this spring, the E. Barrett Prettyman Courthouse in downtown Washington, DC, was buzzing with lawyers, reporters, and interested onlookers jostling between dimly lit courtrooms that hosted everyone from the richest men in Silicon Valley to fired federal workers and the DOGE-aligned officials who terminated them. The sprawling courthouse, with an airy atrium in th

3 tips I use every time I travel to avoid exorbitant roaming fees

Ryan Haines / Android Authority I still remember when my husband got slapped with an exorbitant €70 extra fee on his €10 basic mobile plan because he mistakenly went online for a few minutes during a layover in Turkey. Since then, avoiding roaming fees has been our personal crusade, especially since we like travelling and our basic local data plans have ridiculously expensive fees when we step outside of Europe. Over the years, I’ve put together a three-prong strategy to avoid paying for roami

The best Apple Watch of 2025: Expert tested and reviewed

An Apple Watch isn't just an accessory or an excuse for a second screen around your wrist. After a year of testing out the Apple Watch, I've found it to be a helpful sleep tracker, the world's most convenient timer for when my hands are dirty in the kitchen, a phone-free text or call receiver/sender, and an exercise motivator and mid-workout monitor. The Apple Watch started out as a sleek fitness tracker and has evolved into an essential companion for iPhone users. Apple's smartwatches have an

Augmented Vertex Block Descent (AVBD)

Augmented Vertex Block Descent (AVBD) Vertex Block Descent is a fast physics-based simulation method that is unconditionally stable, highly parallelizable, and capable of converging to the implicit Euler solution. We extend it using an augmented Lagrangian formulation to address some of its fundamental limitations. First, we introduce a mechanism to handle hard constraints with infinite stiffness without introducing numerical instabilities. Second, we substantially improve the convergence in th

'Sinners' Will Stream on Max in July. Here's When to Watch

It doesn't matter if you're going to watch Sinners for the first or the 21st time, the Ryan Coogler-penned original film is worth all your time, and it's coming to Max next month. Rich in blues music, culture, metaphors and Southern gothic vibes, the vampire flick stars Michael B. Jordan as a pair of twin brothers -- Smoke and Stack -- who come back to their Mississippi hometown with big plans. But they encounter a supernatural malevolence unlike anything they've ever seen, and it's threatening

The golden Trump Phone is almost certainly not made in the US

Not content with a real estate empire and the presidency of the United States, the Trump family is wading into the phone wars like it's 2011 with a shiny gold monstrosity called the T1, the marketing of which leans extensively on the narrowest idea of patriotism. Beyond the immediate question — why do this, like, at all? — the T1 invites a question that's perhaps easier to interrogate: How can any modern smartphone claim to be made in the US? Over the last 40 years America has led a massive glo

Nvidia wants in on the nuclear renaissance, invests in Bill Gates-backed TerraPower

TerraPower, the nuclear startup founded and backed by Bill Gates, announced a new $650 million funding round this week. The investment will help the company build its first commercial power plant. Like other nuclear startups, TerraPower has been riding a wave of interest from hyperscalers, data center developers, and, now, chip designers. Nvidia’s venture arm, NVentures, participated in the round, marking its first energy investment. Bill Gates and HD Hyundai, both already on the cap table, al

Deezer starts labeling AI-generated music to tackle streaming fraud

Deezer announced on Friday that it will start labeling albums that include AI-generated tracks as part of its efforts to combat streaming fraud. The company reports that about 18% of the music uploaded each day — more than 20,000 tracks — is now fully AI-generated. Although most of these tracks don’t go viral, Deezer says around 70% of their streams are fake and that they are designed to earn royalties fraudulently. To combat this, AI-generated tracks on Deezer are now clearly tagged. These tr

Iran’s government says it shut down internet to protect against cyberattacks

Earlier this week, virtually everyone in Iran lost access to the internet in what was called a “near-total national internet blackout.” At the time, it was unclear what happened or who was responsible for the shutdown, which has severely limited Iranians’ means to get information about the ongoing war with Israel, as well as their ability to communicate with loved ones inside and outside of the country. Now, Iran’s government has confirmed that it ordered the shutdown to protect against Israel

Tesla partners with Electrify Expo to launch full-weekend EV test drives

Electrify Expo, which has spent the last five years putting on festivals across the U.S. to educate people about electric vehicles, is launching a demo experience where people can take an EV home for a weekend.

Astro Bot’s director on making a PlayStation icon

Astro Bot is filled with whimsy and silliness that makes you want to pay attention to the details. But in a presentation at this year’s Game Developers Conference, director Nicolas Doucet shared one particular aspect of Astro the robot that I hadn’t noticed but blew me away. Doucet talked about how Team Asobi worked hard to give the game a good tempo with things like enemy placement and how you can interact with Astro’s spaceship with the DualSense’s gyro controls on loading screens. One thing

Calorie restriction can help animals live longer. What about humans?

But the full picture is not so simple. Weight loss isn’t always healthy and neither is restricting your calorie intake, especially if your BMI is low to begin with. Some scientists warn that, based on evidence in animals, it could negatively impact wound healing, metabolism and bone density. This week let’s take a closer look at the benefits—and risks—of caloric restriction. Eating less can make animals live longer. This remarkable finding has been published in scientific journals for the last

Google Messages will help you shame your friends into finally turning on RCS (APK teardown)

Edgar Cervantes / Android Authority TL;DR To take full advantage of RCS messaging features, everyone in the chat needs to have RCS enabled. Google Messages is working on a feature that would prompt you to send friends without RCS a message asking them to turn it on. Messaging on Android is better than it’s ever been, and a big part of that is due to the arrival of Rich Communication Services (RCS) support. While that’s absolutely helped start pulling down some of the walls between Android and

This Retro Gaming Keyboard Hits All the Right Nostalgia Vibes and It's a Great Keyboard

As a child of the '90s few things get my nerd brain tingling like good ol' Super Mario. Even hearing my best friend's Mario-themed phone notifications take me back to a simpler time.
