Wi-Fi router vs. mesh system: I compared both - and here's what I'd choose

Maria Diaz/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Routers are cheaper, faster, and easier to set up. Mesh systems fix dead zones with wider coverage. Choose based on budget, home size, and connection needs. With the adoption of remote and hybrid working, having a reliable internet connection at home is imperative -- not just for one device, but for several. If you have a family, maybe even dozens. So what's better, one single access point, or a me

If you are good at code review, you will be good at using AI agents

Using AI agents correctly is a process of reviewing code. If you’re good at reviewing code, you’ll be good at using tools like Claude Code, Codex, or the Copilot coding agent. Why is that? Large language models are good at producing a lot of code, but they don’t yet have the depth of judgement of a competent software engineer. Left unsupervised, they will spend a lot of time committing to bad design decisions. AI agents and bad design Last week I built VicFlora Offline: an offline-friendly PW

Moon Helium Deal Is the Biggest Space Resource Grab Yet

For billions of years, solar winds have bombarded the Moon. Over time, this constant onslaught of charged particles has caused helium-3 to accumulate in the lunar surface. This isotope is rare on Earth, and rising demand from several industries—including quantum computing—has incentivized some companies to explore the possibility of lunar mining. One such company is Interlune, a Seattle-based startup that aims to extract natural resources—primarily helium-3—from the lunar surface. Interlune eve

Premier League Soccer: Livestream Liverpool vs. Everton From Anywhere

Security News This Week: A Dangerous Worm Is Eating Its Way Through Software Packages

New findings this week showed that a misconfigured platform used by the Department of Homeland Security left sensitive national security information—including data related to the surveillance of Americans—exposed and accessible to thousands of people. Meanwhile, 15 New York officials were arrested by Immigration and Customs Enforcement and the New York Police Department this week in or around 26 Federal Plaza—where ICE detains people in what courts have ruled are unsanitary conditions. Russia c

Google isn’t kidding around about cost cutting, even slashing its FT subscription

Google is ending its enterprise subscription to the Financial Times, and it’s not the only enterprise media subscription on the chopping block, sources say. The cuts reflect broader cost-reduction efforts at the search giant, even as the company reports strong financial performance. Google has been implementing cost reductions across 2025, including eliminating 35% of managers who oversee teams of three people or fewer, and offering voluntary exit programs across multiple divisions since Janu

Trump and Xi discuss future of TikTok in US

Trump and Xi discuss future of TikTok in US Watch: Trump says TikTok deal approved by Chinese President Xi TikTok, which is run by Chinese firm ByteDance, was previously told it had to sell its US operations or risk being shut down. China's official state news agency Xinhua left the outcome of their discussion less clear, with Xi quoted as saying that Beijing "welcomes negotiations over TikTok". Trump wrote on Truth Social that the call was "productive" and he "appreciated" Xi's approval of

Your passkeys could be vulnerable to attack, and everyone - including you - must act

Xmonad seeking help for Wayland port (2023)

2023-10-06 Wayland We on the XMonad devteam (Tomáš, Tony, Yecine, and myself) have been collecting contributions for the past two years with an eye toward paying someone to work on a port of XMonad to Wayland, since none of us is up to the task. We think we now have enough contributions coming in monthly to pay for someone to work with us on it. Problem is, we have no idea who can do this. So this is a call for help, looking for someone who can write it. There is an existing project but it’s

Mini: Tonemaps (2023)

Good day. One of the first things you learn about shaders is that color values range from 0.0 to 1.0. This is known as 8-bit “unorm” color, because each channel has 256 color values, is unsigned (meaning no negatives) and normalized to the 0.0 to 1.0 range. Most of the time, we don’t need to think about this because 8-bits is enough for outputting colors to the screen. Sometimes, blending 8-bit colors is just not enough though. Today I want to show demonstration when you should care and what to

Starship will soon fly over towns and cities, but will dodge the biggest ones

Some time soon, perhaps next year, SpaceX will attempt to fly one of its enormous Starship rockets from low-Earth orbit back to its launch pad in South Texas. A successful return and catch at the launch tower would demonstrate a key capability underpinning Elon Musk's hopes for a fully reusable rocket. In order for this to happen, SpaceX must overcome the tyranny of geography. Unlike launches over the open ocean from Cape Canaveral, Florida, rockets departing from South Texas must follow a narr

Samsung Announces Plans to Plaster Your Smart Fridge With Digital Advertisements

If it's digital, it can have a screen. And if it has a screen, it can show you ads. That's the logic that dominates the electronics and tech industry these days, and it's now coming to bear on an essential household appliance: the fridge. We call it a fridge, but after reading this, you may yearn for the days when they functioned as a mere icebox. Friend of the advertising industry Samsung announced that it will start plastering ads on its Family Hub™ refrigerators in the US, rendering your bl

US and China agree to agree on a TikTok deal

The long-promised deal to "save" TikTok remains elusive even as the US and China seem to be inching toward an agreement. On Friday, President Donald Trump did little to clarify where the deal currently stands following a call with Chinese President Xi Jinping. In a post on Truth Social, Trump said both that the two had "made progress" on "approval of the TikTok Deal" and that he "appreciate[s] the TikTok approval." Trump also told reporters in the Oval Office that "he approved the TikTok deal,"

‘Night of the Reaper’ Is a Retro Babysitter Slasher With a Mystery Twist

Night of the Reaper begins with a familiar slasher movie scenario: a babysitter being stalked by a killer. The masked menace puts on a big show of toying with her, leaving creepy notes that almost feel like a prank until the danger gets all too real. It’s a freaky opening sequence that signals director and co-director Brandon Christensen (Still/Born, Z) is well familiar with the horror tropes his movie is leaning into—and you can tell he knows his audience will pick up on them too. Night of th

Rails Needs New Governance

The title card of Tom Stuart’s presentation, The DHH Problem. Ages ago, when I was still a student, I taught myself Ruby on Rails for my senior thesis and fell in love. Fifteen years later, and I’ve used Rails at every job I’ve ever held in the tech industry. Fifteen years, and I still love Rails! But there’s something rotten at its core, and we share a name. The DHH Problem Back in 2014, Tom Stuart delivered a pithy yet salient lightning talk at the Scottish Ruby Conference titled The DHH Pr

After a very slow start, Europe’s reusable rocket program shows signs of life

No one could accuse the European Space Agency and its various contractors of moving swiftly when it comes to the development of reusable rockets. However, it appears that Europe is finally making some credible progress. This week, the France-based ArianeGroup aerospace company announced that it had completed the integration of the Themis vehicle, a prototype rocket that will test various landing technologies, on a launch pad in Sweden. Low-altitude hop tests, a precursor for developing a rocket

In a win for science, NASA told to use House budget as shutdown looms

The situation with the fiscal year 2026 budget for the United States is, to put it politely, kind of a mess. The White House proposed a budget earlier this year with significant cuts for a number of agencies, including NASA. In the months since then, through the appropriations process, both the House and Senate have proposed their own budget templates. However, Congress has not passed a final budget, and the new fiscal year begins on October 1. As a result of political wrangling over whether t

Apple releases watchOS 26.0.1, but very few users will get it

Apple is rolling out a watchOS 26.0.1 build that appears to be specific to the Apple Watch Ultra 3. Here’s what’s new. What’s new with watchOS 26.0.1? In an unusual move for a Friday afternoon, Apple just rolled out a system update for the Apple Watch, but you will only see it if you’re among the lucky users who already got their hands on the new Apple Watch Ultra 3.

Dialing Up the Internet Phonebook

You might’ve heard of the Internet Phone Book, a collection of poetic, interesting, personal websites, and essays about websites, collected by Kristopher and Elliott. We chatted about how the phonebook was made, and about why they’re optimistic about the web that’s made by real people and artists. TLDR: Make a website, it’ll save your soul. Because Kinopio sponsored the first printing of the phone book, I was sent three extra copies. I wasn’t sure what to do with them though. When I asked what

Tim Cook Swears Tariffs Aren’t to Blame for iPhone 17 Pro Price Hike

Apple CEO Tim Cook wants everyone—especially Donald Trump—to know that the company’s new iPhone Pro price hike has nothing to do with tariffs. “There’s no increase for tariffs in the prices to be totally clear,” Cook told CNBC’s Jim Cramer on Friday, the launch day for Apple’s iPhone 17 lineup. Earlier this month, Apple announced it would be raising the starting price for its most advanced iPhone by $100. For the first time since the iPhone X debuted in 2017, Apple’s entry-level Pro model star

From iPhone 17 to Meta Glasses, It Was a Big Week for Tech News

Many of us remain glued to the story of late-night TV host Jimmy Kimmel's indefinite suspension by ABC over controversial comments included in his Sept. 15 monologue. Hard-hitting (and hilarious) reactions from colleagues like Jon Stewart, Stephen Colbert, Seth Meyers and Jimmy Fallon have helped the story dominate headlines all week. If you're looking to take a break from doomscrolling, it was a huge week for tech news. The new iPhones are on sale today; Meta unveiled its latest VR glasses (at
