Meta’s failed smart glasses demos had nothing to do with the Wi-Fi

Posts from this author will be added to your daily email digest and your homepage feed. Meta ran into some spectacularly embarrassing technical issues during the live demos of its new smart glasses this week, and now we know why. Andrew Bosworth, Meta’s chief technology officer, explained in an Instagram AMA why two notable demos — an influencer asking the AI assistant for cooking instructions, and Mark Zuckerberg attempting to pick up a WhatsApp call — failed. “When the chef said ‘hey Meta, s

How to Debug Chez Scheme Programs (2002)

How to Debug Chez Scheme Programs R. Kent Dybvig August 2002 When a program fails to operate as it should, it is said to have a bug. A bug is the root cause of an observed behavior, such as failure to terminate, failure to perform some action, termination with an error message, or merely producing incorrect results. The process of debugging a program is one of finding all of the bugs and "exterminating" them. This process first requires feeding the program a representative set of test cases,

A postmortem of three recent issues

Between August and early September, three infrastructure bugs intermittently degraded Claude's response quality. We've now resolved these issues and want to explain what happened. In early August, a number of users began reporting degraded responses from Claude. These initial reports were difficult to distinguish from normal variation in user feedback. By late August, the increasing frequency and persistence of these reports prompted us to open an investigation that led us to uncover three sepa

Launch HN: Ghostship (YC S25) – AI agents that find bugs in your web app

Hi HN, we're Jesse and Gautham. We're building Ghostship ( https://tryghostship.dev/ ). Ghostship lets you find bugs in your web app by entering in your URL and describing a user journey. Here's a video of Ghostship in action: https://www.loom.com/share/dec264ae32f94d50adb141c9246837c3?.... For over half our lives, we've been developers and we've done tons of user-facing projects like a coding competition I built called CerealCodes or freelancing projects on Upwork. The biggest problem we fac

NT OS Kernel Information Disclosure Vulnerability

Reading Time: 4 minutes Introduction Microsoft mitigated many traditional kernel information leaks starting with Windows 11/Windows Server 2022 24H2, including calls such as NtQuerySystemInformation() (when used with the SystemModuleInformation class), by suppressing kernel base addresses unless the caller had the SeDebugPrivilege , typically reserved for administrative processes. That change effectively neutered one of the most accessible KASLR bypass techniques, and, without knowledge of the

Things you can do with a debugger but not with print debugging

Things you can do with a debugger but not with print debugging People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger. Which is a shame, because while debug logging is convenient at times, debuggers can do some things which you can’t easil

‘Witch Hat Atelier’ Anime Studio Explains Delay, Vows to Do Justice to Manga’s Spellbinding Artistry

Studio Bug Films hopes its adaptation of Kamome Shirahama's manga will be as big as 'Lord of the Rings' for anime fans. Studio Bug Films recently delivered the deflating news that its anime adaptation of Witch Hat Atelier would be delayed to 2026. In the wake of its announcement, the studio gave fans an update about the nature of its delay and reaffirmed its commitment to doing the best possible job transforming manga pages into animation. In an X/Twitter social media post, which links out to

Google is already shoveling out a fix for Pixel 10’s screen snow

Google is now rolling out a fix for the so-called “screen snow” bug affecting some Pixel 10 devices.

Look Out for Bugs

Look Out For Bugs One of my biggest mid-career shifts in how I write code was internalizing the idea from this post: Don’t Write Bugs Historically, I approached coding with an iteration-focused mindset — you write a draft version of a program, you set up some kind of a test to verify that it does what you want it to do, and then you just quickly iterate on your draft until the result passes all the checks. This was a great approach when I was only learning to code, as it allowed me to iterate

WhatsApp Just Patched a ‘Zero Click’ Bug Being Used to Hack Apple Users

On Friday, WhatsApp announced that it had patched a software vulnerability that was being used by unknown hackers to target specific users of Apple products and hack them with spyware. WhatsApp, which is owned by Meta, said in an advisory that the previously unknown bug “may have been exploited in a sophisticated attack against specific targeted users.” The vulnerability is officially dubbed CVE-2025-55177. TechCrunch notes that this week, WhatsApp fixed the bug while last week, Apple fixed an

Show HN: Magic links – Get video and dev logs without installing anything

Hey HN, For a while now, our team has been trying to solve a common problem: getting all the context needed to debug a bug report without the endless back-and-forth. It’s hard to fix what you can't see, and console logs, network requests, and other dev data are usually missing from bug reports. We’ve been working on a new tool called Recording Links. The idea is simple: you send a link to a user or teammate, and when they record their screen to show an issue, the link automatically captures a

Hardware Flaw in Apple A16 Chip: Debug Logic Active on Production Devices

A16-FuseBypass: Debug Logic Enabled on Production Apple Silicon Overview This repository documents a critical hardware-level vulnerability in the Apple A16 Bionic chip used in iPhone 14 Pro Max and related devices. The flaw allows debug logic—meant strictly for development silicon—to be executed on production-fused devices ( dev-fused = 0 ) running stock, unmodified iOS with debug = 0x0 . No jailbreak. No provisioning profile. No tampering. Just flawed hardware trust enforcement. Summary of

Sometimes CPU cores are odd

One of the biggest lessons that I've learned in my career is that all software has bugs, and the more complicated your software gets the more complicated your bugs get. A lot of the time those bugs will be fairly obvious and easy to spot, validate, and replicate. Sometimes, the process of fixing it will uncover your core assumptions about how things work in ways that will leave you feeling like you just got trolled. Today I'm going to talk about a single line fix that prevents people on a large

Yorgos Lanthimos’ New Film Puts Emma Stone at the Center of an Alien Environmentalist Conspiracy

Director Yorgos Lanthimos has made a habit of collaborating with Emma Stone specifically on dark comedy dramas with light sci-fi themes, such as 2023’s Poor Things and 2024’s Kinds of Kindness. And the trailer for their latest team-up, Bugonia, contains much of the same eclecticism, setting up a paranoia thriller that’s equal parts about environmentalism and extraterrestrials. Bugonia, inspired by Korean director Jang Joon-hwan’s 2003 sci-fi film, Save The Green Planet!, follows high-powered CE

Why Pooping on Planes Might Actually Be a Good Thing

Researchers have developed a new critical warning system for the spread of antimicrobial resistant (AMR) superbugs: poop and pee from airplane bathrooms. Scientists predict that by 2050, AMR superbugs, or pathogens that don’t respond to antimicrobial medicines, might take more lives than cancer. As such, it’s critical for countries to keep an eye on the global propagation of these dangerous pathogens, which can travel with people, in order to best prepare for future infections. In a study publi

Samsung’s latest One UI 8 beta is causing a hilarious moon-related camera glitch

Joe Maring / Android Authority TL;DR Galaxy devices running One UI 8 Beta 4 are experiencing a new bug. The issue turns the moon purple after you pass 30x zoom. These moon photos also appear blurrier compared to photos taken with a device running One UI 7. When it comes to betas, bugs come with the territory. Sometimes those bugs can be of the serious variety, causing crashes or other system problems. But other times, bugs can fall into the funny or weird category. The new bug that One UI 8

Google says a fix for Gemini’s shame spiral is on its way

Ryan Haines / Android Authority TL;DR A Gemini bug results in the AI getting stuck in an infinite loop of critical responses, including calling itself a disgrace. Google’s Logan Kilpatrick says that the company is working on fixing the bug. If you check in on Gemini yourself, the chatbot will assure you that it does not have feelings and it’s just a bug. While most people have been getting along fine with Gemini, some users have noticed a bug where the AI chatbot seemingly spirals with respo

Stay Bite-Free With the Best Bug Sprays for 2025

What we like about it: For those who want to avoid chemicals altogether, a lemon eucalyptus insect repellent is a gentler way to stave off bugs and their bites. I tried a few different lemon eucalyptus bug sprays, and Natrapel came out on top. Lacking the two chemicals proven to repel insects, it's natural to think this bug spray isn't as effective as its DEET- or picaridin-containing counterparts. The CDC and EPA recognize lemon eucalyptus oil as an effective insect repellent. The Natrapel bott

Google says its AI-based bug hunter found 20 security vulnerabilities

The First Lunar Road Trip

Today in 1971, David Scott and James Irwin went for a drive—but this was no joyride. Scott and Irwin, NASA astronauts on the Apollo 15 moon mission, became the first people to burn rubber on the moon’s surface. The battery-powered Lunar Roving Vehicle, or “moon buggy,” could travel up to a cool 12 miles per hour, and took astronauts on longer journeys than previously possible during brief, cumbrous walks in their bulky suits. The buggy weighed a mere 77 pounds on the moon and could whisk around

‘Ok Google, turn on the lights’ is mysteriously broken for many users right now

Ryan Haines / Android Authority TL;DR Many users are reporting not being able to control lights or groups of lights with an ‘Ok Google’ command. I noticed this issue on my speakers yesterday, but thought it was a random bug. It seems more widespread, and the Google Nest account has acknowledged the issue. Yesterday evening, as I went to bed, I told my Google Nest Audio, “Hey Google, turn off all the lights.” Normally, this is one of the easiest commands, and my success rate with it is better

AI slop and fake reports are coming for your bug bounty programs

So-called AI slop, meaning LLM-generated low-quality images, videos, and text, has taken over the internet in the last couple of years, polluting websites, social media platforms, at least one newspaper, and even real-world events. The world of cybersecurity is not immune to this problem, either. In the last year, people across the cybersecurity industry have raised concerns about AI slop bug bounty reports, meaning reports that claim to have found vulnerabilities that do not actually exist, be

Cursor’s New Bugbot Is Designed to Save Vibe Coders From Themselves

But the competitive landscape for AI-assisted coding platforms is crowded. Startups Windsurf, Replit, and Poolside also sell AI code-generation tools to developers. Cline is a popular open-source alternative. GitHub’s Copilot, which was developed in collaboration with OpenAI, is described as a “pair programmer” that auto-completes code and offers debugging assistance. Most of these code editors are relying on a combination of AI models built by major tech companies, including OpenAI, Google, an
