How easy is it for a developer to "sandbox" a program?

# source code sandboxing Sandboxing is when a developer limits available system resources to a program from within its own source code. A classic example is calling chroot(2) to change the root file-system to an empty directory so that the program cannot scribble into the root file-system. int main(void) { /* Program has full file-system access. */ chroot("/var/empty"); chdir("/"); /* File-system root re-rooted in /var/empty. */ int fd = open("/etc/passwd", O_RDONLY); /* Tried to open /var/empty

Piloting the Kite-Powered Sailboat Aiming to Be World's Fastest

Table of Contents Piloting the Kite-Powered Sailboat Aiming to Be World's Fastest Cutting through the water on a triple-hull sailboat pulled by a giant kite, members of the SP80 team are challenging the world sailing speed record off the coast of Southern France, one gust of wind at a time.

SP80 "There is nothing to earn at the end, except that you are proud to achieve it," says co-founder Benoit Gaudiot, who is also

The Mysterious Inner Workings of Io, Jupiter’s Volcanic Moon

The original version of this story appeared in Quanta Magazine. Scott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, catching the first glimpse of active volcanism on a world other than Earth. Umbrella-shaped outbursts of magmatic matter rocketed into space from all over Io’s surface. “They looked amazingly beautiful,” said Bolton, who is now based a

How to build the best keyboard in the world

The term “endgame,” among keyboard enthusiasts, is sort of a running gag. Endgame is when you finally dial in your perfect layout, case, features, switches, and keycaps, so you can stop noodling around with parts and get on with whatever it is you actually use the keyboard for — work, presumably. Then a few months later you see something shiny and start over. In the search for endgame, most of us have to compromise somewhere — usually time or money. Sometimes the thing you’re looking for just d

Norbauer Seneca review: a $3,600 luxury keyboard for the keyboard obsessed

Some people can tell great wine from okay wine. They go on wine tastings, take wine tours. They tend to spend more money on wine than most. I am not one of those people. I can tell wine from vinegar if you show me the bottle. I am just a little bit obsessed with keyboards, though. I have spent the past couple of months typing on the Seneca, a fully custom capacitive keyboard that starts at $3,600 and might be the best computer keyboard ever built. I’ve also made a bunch of other people type on

“Language and Image Minus Cognition”: An Interview with Leif Weatherby

by Robin Manley Leif Weatherby is an Associate Professor of German at New York University, where he directs the Digital Theory Lab. Robin Manley spoke with Dr. Weatherby about his latest book, Language Machines: Cultural AI and the End of Remainder Humanism (University of Minnesota Press, 2025), which argues that Large Language Models (LLMs) have effected a separation of cognition from language and computation in a form that corresponds to earlier structuralist theories. Robin Manley: In the i

I'm a Fiend for Horror and Westerns. Netflix Has One of the Best Genre Mashups Ever Made

Father's Day is coming up and, if you're like me, you're searching for the perfect movie to watch on the big day. Well, as a dad myself, I can easily find comfort in the tried and true classics like National Lampoon's Vacation, Once Upon a Time in America or even The Shawshank Redemption. There's no arguing that those titles are stereotypical "dad" movies. But I'm not a stereotypical dad. My cinematic tastes usually lead me down an alternate path. Yes, I love me a good western but I'm also a d

Suspect in Minnesota Shooting Linked to Security Company, Evangelical Ministry

A man named Vance Boelter allegedly shot and killed Melissa Hortman, a Democratic Minnesota state representative, and her husband Mark Hortman at their home at some point early Saturday morning while, according to law enforcement, impersonating a police officer. He also allegedly shot state senator John Hoffman and his wife Yvette Hoffman at their home. They are alive, but remain in critical condition. Law enforcement has said they found a manifesto and hit list in the alleged suspect’s car, wh

I found a simple toggle to get rid of ads in my Gmail inbox, and I can’t recommend it enough

Calvin Wankhede / Android Authority I hate nothing more than advertising online that blends into the rest of the content. That’s especially true when it shows up in places where I least expect it, like my email inbox. In the Gmail app, the biggest offender is the “Sponsored” emails pictured above. These ads often show up like a regular message and look almost the same as any other email — sender, subject line, and all. Some ads are even worse and take up significant real estate to show you prod

Clones, sandworms, scrapbooking and other new indie games worth checking out

It's been a big week or so in the video game realm between the arrival of the Nintendo Switch 2 (our review is now live) and Summer Game Fest.

My favorite lightweight Windows laptop was already affordable - but now it's $250 off

When I first picked up the Asus Zenbook A14, I thought I was holding an empty prototype. Then it turned on, and the brilliant OLED display proved me wrong. At 2.1 pounds, it's not just one of the lightest laptops I've used; it's also well-balanced -- both physically and in terms of hardware -- and epitomizes the thin, battery-efficient category that's exploded over the last year. Also: The best lightweight laptops of 2025: Expert tested It's my pick for the best lightweight laptop, and was als

Tired of vacuuming your house? You and us both. It’s just not a fun task, no matter how you slice it. And it’s a thankless one. The end result is fine, sure, because you get floors that are clean. But who wants to keep taking time out of their day to clean? Couldn’t be us. If your floors are constantly covered in pet hair, crumbs, or tracked-in dirt, the idea of a robot vacuum doing the heavy lifting while you kick back (or, let’s be real, tackle a million other things) is pretty appealing.

AI as Your Therapist? 3 Things That Worry Experts and 3 Tips to Stay Safe

Amid the many AI chatbots and avatars at your disposal these days, you'll find all kinds of characters to talk to: fortune tellers, style advisers, even your favorite fictional characters. But you'll also likely find characters purporting to be therapists, psychologists or just bots willing to listen to your woes.

Tern GSD S10 Electric Cargo Bike Review: The Best Little Electric Cargo Bike

In true Pacific Northwestern summer fashion, I have been riding around with multiple cubic feet of wood and soil in the panniers of the test Tern GSD S10. This is the most popular electric cargo bike in my neighborhood, and I personally contributed to its popularity. It's the model of electric cargo bike that I bought to take my kids to school and to carry pallets around the city. Every day, I see parents carting their kids around in Tern Storm Boxes.

Apple begins selling latest M4 MacBook Air models on its refurbished store

Today, Apple has begun selling refurbished configurations of its recently released MacBook Air with M4 chip – with a roughly 15% discount compared to MSRP. This follows the addition of Apple Watch Ultra 2 in Black and M4 Max/M3 Ultra Mac Studio earlier this week.

Whatever Happened to Sandboxfs?

Back in 2017–2020, while I was on the Blaze team at Google, I took on a 20% project that turned into a bit of an obsession: sandboxfs. Born out of my work supporting iOS development, it was my attempt to solve a persistent pain point that frustrated both internal teams and external users alike: Bazel’s poor sandboxing performance on macOS. sandboxfs was a user-space file system designed to efficiently create virtual file hierarchies backed by real files—a faster alternative to the “symlink fore

MacBook Air vs. MacBook Pro: Which MacBook Should I Buy?

If you're having trouble deciding between the cheaper and lighter MacBook Air or spending more for the more powerful MacBook Pro, you've come to the right place. The MacBook Air and Pro don't look all that different from one another, but there are key differences -- from cost and components to performance and battery life -- that you need to know to pick the right one.

Someone Somehow Survived That Massive Boeing Jet Explosion

On Thursday, a Boeing jet crashed just moments after taking off from an airport in Ahmedabad in western India. The Air India airliner, carrying 242 passengers, slammed into a nearby medical college and exploded in an enormous fireball. Somehow, one man survived: 38-year-old Viswash Kumar Ramesh. "I don't know how I am alive," Viswash said, according to his younger brother Nayan Ramesh, as quoted by the New York Times. In a video widely shared on social media, the India-born British citizen ca

Watching This Humanoid Robot Sort Packages Is Quite Something

Yep, they're definitely coming for our jobs. Package Deal Earlier this year, humanoid robotics company Figure showed off its Figure 02 robot using a sophisticated visual language system called Helix to sort packages at a logistics warehouse.

Just three months later, the company has published an update about its Helix learning-based approa

I convinced HP's board to buy Palm and watched them kill it

I've never shared this story publicly before—how I convinced HP's board to acquire Palm for $1.2 billion, then watched as they destroyed it while I was confined to bed recovering from surgery. This isn't just another tech failure analysis. I was the HP Chief Technology Officer who led the technical due diligence on Palm. I presented to Mark Hurd and the HP board, making the case for moving forward with the acquisition. I believed we were buying the future of mobile computing. Then I watched it

The best Chromebooks for students in 2025: Expert tested and reviewed

Let's face it: having a laptop for school is a necessity. But toting around a bulky, slow computer from five years ago is not the vibe. Opting for a Chromebook is a solid choice for students: they're lightweight, fast, and typically cost far less than Windows PCs or Apple MacBooks. Chromebooks run on ChromeOS, a streamlined operating system that integrates with Google Drive, making it easy to navigate to apps like Google Docs, Google Drive, and Gmail so you can stay on task and in touch with te

ChatGPT Tells Users to Alert the Media That It Is Trying to ‘Break’ People: Report

ChatGPT’s sycophancy, hallucinations, and authoritative-sounding responses are going to get people killed. That seems to be the inevitable conclusion presented in a recent New York Times report that follows the stories of several people who found themselves lost in delusions that were facilitated, if not originated, through conversations with the popular chatbot. In the report, the Times highlights at least one person whose life ended after being pulled into a false reality by ChatGPT. A 35-yea

The Plane That Crashed Yesterday Was the Same One a Dead Boeing Whistleblower Warned About

Last year, a former quality manager at Boeing warned that the factory that made the 787 Dreamliner—one of the company’s newer models of airplane—was plagued by shoddy work practices and poor oversight. John Barnett, who had worked for the airplane manufacturer for many years before becoming one of its most outspoken critics, said that Boeing was building the planes with ‘sub-standard’ parts and that its mandate of speed and efficiency was endangering lives. Barnett, who refused to fly on the Dre
