Show HN: Zig-DbC – A design by contract library for Zig

Hi everyone, I've made an open-source library for using design by contract (DbC) principles in the Zig programming language. It's called Zig-DbC, and it currently provides the following features: - A simple API to define preconditions, postconditions, and invariants. - Contracts are active in `Debug`, `ReleaseSafe`, and `ReleaseSmall` modes to catch bugs early. - All checks are removed at compile time in `ReleaseFast` mode for zero performance cost. - An optional mode to handle partial sta

YouTube Music gets another music discovery tool that Spotify doesn’t have

Edgar Cervantes / Android Authority TL;DR Google is testing a new Daily Discover feed in YouTube Music. Like the existing weekly discover, the daily discover aims to help you find artists or music similar to what you already listen. Google only appears to be testing it at the moment, as the feature hasn’t rolled out widely. Although its supremacy is contentious, YouTube Music is easily among the top five music and podcast streaming services globally. Its popularity naturally stems from the f

Funding Open Source like public infrastructure

To protect the digital foundation of essential government services, governments should invest in Open Source as public infrastructure and shift from consumption to contribution. Fifteen years ago, I laid out a theory about the future of Open Source. In The Commercialization of a Volunteer-Driven Open Source Project, I argued that if Open Source was going to thrive, people had to get paid to work on it. At the time, the idea was controversial. Many feared money would corrupt the spirit of volunt

Mubook – N100 x86 NAS Carrier Board Designed for Hackclub Highway

Mubook Mubook is a "portable" x86 based system that is designed to house both mini PC and homelab functionalities while still being small enough to be easily carried and expandable enough for processor upgrades. The project itself is a submission to Hackclub Highway and has the capability to support 4 3.5 inch HDDs and M.2 cards while maintaining upgradeability and much higher performance over other SoM boards with its Intel N100 processor.

Spider-Man, Spider-Man, does whatever a spider can, and PlayStation Plus subscribers can become the famous web-slinger in Marvel's Spider-Man on Aug. 19. PlayStation Plus is Sony's version of Xbox Game Pass, and it offers subscribers a large and constantly expanding library of games. There are three PlayStation Plus tiers -- Essential ($10 a month), Extra ($15 a month) and Premium ($18 a month) -- and each gives subscribers access to games. However, only Extra and Premium tier subscribers can a

PSA: YouTube will start guessing your age from today (Updated)

Edgar Cervantes / Android Authority TL;DR YouTube will start estimating the age of its US viewers beginning today, August 13. The platform will use AI to determine if you are under 18 and automatically apply age-appropriate experiences to your account. You can dispute the age estimation by providing a government ID, selfie, or a credit card. Update, August 13, 2025 (4:59 PM ET): Just as promised, YouTube’s new age checks have gone live, and users are already reporting running into restrictio

Apple's 'tabletop robot' companion rumored for 2027 launch

Apple is still hard at work on becoming a relevant player in AI. The latest missive from Mark Gurman at Bloomberg suggests that Apple is shifting its artificial intelligence goals to center on new device segments. Sources reportedly told the publication that Apple has a slate of new smart home products in the works that could help pivot its lagging AI strategy. The center of the new lineup is a tabletop AI companion that has been described as an iPad on a movable robotic arm. It would be able t

Fighting with YouTube to show a preview image

TLDR: Click here for code to implement a lightweight, resilient clickable YouTube preview. YouTube videos are expensive to load on a web page. This compounds if you want your page to display many videos at the same time for the user to choose from. Before the user even plays the video, it loads 4MB onto your previously zippy page. Of course, YouTube does a decent job of caching these resources, but your browser is still doing all this work, creating another complete page context per video, exe

Google will help you pester your friends into turning location sharing on (APK teardown)

TL;DR Google’s Find Hub combines resources for tracking devices and sharing location with friends and family. Users need to positively consent first before their location is shared with anyone. The app is working to build an easy way for you to request your friends grant that access. Smartphones are picking up new features and abilities all the time, and while some of those are pushed out to us enabled by default, others are going to require us to make the intentional choice to opt in. And wh

PUBG: Battlegrounds will leave PS4 and Xbox One behind later this year

PUBG: Battlegrounds is finally ready to ditch last-gen consoles. On Wednesday, the developer said that the game will transition to PS5 and Xbox Series X/S on November 13. Although the battle royale has been playable on current-gen consoles all along, it was running as a PS4 or Xbox One game. That helped it cast a wide net (and probably make more money), but it also came with technical limitations. The company said the move to current-gen will "provide our players with a more stable gameplay env

Antarctica’s Ghost Hunters: Inside the World’s Biggest Neutrino Detector

Neutrinos are strange little things. This tiny, enigmatic particle with no charge exists in virtually every corner of the universe, but without powerfully sensitive, sophisticated instruments, physicists would have no way of knowing they exist. In fact, trillions are passing through you every second. Physicists devise all sorts of ways to coax neutrinos into the detection range. But IceCube—which celebrates its 20th anniversary this year—stands out in particular for its unique setup: 5,160 digi

The new War of the Worlds movie is even more terrible than you’ve heard but also hilarious

There’s a micro-genre of film called “screenlife movies,” where all of the action takes place on a desktop computer. In 2014, Unfriended made a horror movie out of video chat and text messages, and it was successful enough to inspire a sequel. The more thoughtful Searching from 2018, in which a father attempts to find his missing daughter, felt novel and a bit more promising for the genre, even if an hour and a half really tested the amount of time you could look at a scrunched John Cho and Mac

You’re not making the most of YouTube and YouTube Premium if you’re not using this trick

Rita El Khoury / Android Authority Back in April, I watched dozens of YouTube videos about Budapest before traveling there. When I returned home, my YouTube home page was still full of Budapest videos, and although I haven’t clicked on any since then, I still get them in my recommendations to this day. The same happened when I obsessed over lawnmowers before buying one, and the Ninja Woodfire grill before I splurged on it. YouTube keeps recommending videos for things I was momentarily intrigued

All-In on Omarchy at 37signals

We're going all-in on Omarchy at 37signals . Over the next three years, as the regular churn of hardware invites it, we're switching everyone on our Ops and Ruby programming teams to our own Arch-derived Linux distribution (and of course sharing all the improvements we make along the way with everyone else on Omarchy!). It's funny how nobody bats an eye when the company mandate is to use Macs or Windows, but when the prescription is Linux, it's suddenly surprising. It really shouldn't be. Y

YouTube backlash begins: “Why is AI combing through every single video I watch?”

Tens of thousands of YouTubers are raging against YouTube's plan to use AI to detect underage users in the US. On Tuesday, a Change.org petition rapidly neared its 50,000-signature goal, with tens of thousands hoping that with enough users protesting, the wide rollout of the AI age checks might be stopped. They fear the age checks will make it harder to access content they love while staying anonymous on the platform YouTube's age verification system estimates user ages by interpreting a "vari

Match to pay $14M to the FTC due to false advertising and other deceptive practices

Back in 2019, the U.S. Federal Trade Commission (FTC) sued the dating app giant Match Group, accusing it of deceiving Match.com users into purchasing subscriptions through misleading means. Now, after six years, the company— which operates popular dating apps Match, Tinder, OkCupid, Hinge, and Plenty of Fish—has agreed to a $14 million settlement, as announced by the FTC on Tuesday. The FTC stated that the $14 million will be used to provide “redress to injured consumers.” According to the la

Uber Freight CEO joins self-driving truck company Waabi, says era of autonomous big rigs on U.S. roads is here

Lior Ron, founder and CEO of Uber Freight, is joining self-driving truck startup Waabi as chief operating officer. The move, Ron says, is based on his belief that the era of autonomous big rigs on the roads at scale is here, with the freight industry to be transformed by the economics of driverless technology in the semi cab. "The first decade of my career in logistics was building Uber Freight, putting the rails in place to usher in the era of digitalization for logistics," Ron said. "It's ti

One of Google’s YouTube channels looks like it was hacked to promote crypto

Screenshots show the account promoting crypto trading prior to going offline. Security is hard. Even with all the fantastic tools we have access to, designed to help keep our accounts and information private, actually maintaining good security requires ongoing effort, making sure we’re taking full advantage of

Uber Freight CEO Lior Ron leaves to join self-driving startup Waabi as COO

Self-driving truck maker Waabi has hired autonomous vehicle industry veteran and Uber Freight CEO, Lior Ron, to step in as chief operating officer, as the startup looks to scale its commercial operations ahead of its planned launch of driverless trucks on public highways later this year. Rebecca Tinucci, who previously spent six years building Tesla’s charging network before the automaker gutted its charging staff last year, will take over as head of Uber Freight. Ron will stay on as Uber Freig

StubHub IPO is back on for September after ticketing company delayed plans on tariff concerns

StubHub, the ticketing marketplace that spun out of eBay in 2020, has resumed its plans to go public and is now aiming to hold its IPO next month, CNBC has learned. The company originally paused its IPO plans in April as the stock market was reeling from President Donald Trump's "liberation day" tariffs. The decision came after StubHub submitted its prospectus in March indicating it would list on the New York Stock Exchange under the ticker "STUB." StubHub now expects to kick off its IPO roads

GitHub will be folded into Microsoft proper as CEO steps down

Microsoft has owned GitHub since 2018, but the widely used developer platform has operated with at least a little independence from the rest of the company, with its own separate CEO and other executives. But it looks like GitHub will be more fully folded into Microsoft's org chart starting next year—GitHub CEO Thomas Dohmke announced today that he would be leaving GitHub and Microsoft "to become a founder again." "GitHub and its leadership team will continue its mission as part of Microsoft’s

Revel is ending its ridesharing operation to focus on EV charging

Revel Transit is shutting down its rideshare operation in NYC, as reported by Bloomberg. The company will instead focus its efforts on EV charging. It's also seeking buyers for its fleet, including the 165 for-hire vehicle license plates it owns. "At the end of the day, rideshare is a very competitive market and asset-heavy. It’s low margin," CEO Frank Reig said. “We have made the difficult decision that the best way we can keep the EV transition moving forward is by ending our rideshare servic
