Checking that functions are constant time with Valgrind (2010)

Information leaks via timing side channels can be deadly. You can steal RSA keys from other processes on the same host, extract the kernel's dm_crypt keys and steal AES keys over the network. In order for a function to be constant time, the branches taken and memory addresses accessed must be independent of any secret inputs. (That's assuming that the fundamental processor instructions are constant time, but that's true for all sane CPUs.) However, it's tough to write constant time functions.

Sierra’s Dream Chaser is starting to resemble a nightmare

The Dream Chaser spaceplane, which has been under development for two decades, now seems like it might be further than ever from taking flight. On Thursday, NASA, confirming an earlier Ars Technica report, said the first flight of the winged spacecraft will no longer berth with the International Space Station. Rather, the space agency said, the Dream Chaser program would be "best served" by a free flight demonstration. "Development of new space transportation systems is difficult and can take

Battery startup Moxion went bankrupt. Now its founder is back to ‘finish what we started’

Just over a year ago, Moxion Power closed its doors, adding its name to a list of high-profile bankruptcies that roiled the climate tech world in 2024. The portable battery startup had raised more than $110 million in a bid to replace diesel generators at festivals and construction sites, but even that wasn’t enough to get it through the valley of death. Moxion laid off more than 400 employees and its assets were liquidated. Now, the startup’s co-founder, Paul Huelskamp, and several former Moxi

The best eco-friendly phone cases for 2025

We all want to protect our phones from the inevitable drops, scratches and tumbles of daily life, but what if your cell phone case could protect more than just your device? The best eco-friendly phone cases offer a great blend of durability and sustainability, helping to reduce plastic waste and better the planet. Made from natural materials like biodegradable plastics, recycled ocean waste or even sustainable bamboo, eco-friendly and compostable phone covers prove that you don’t have to sacr

Apple Wallet digital ID support expands to yet another US state

Very slowly but surely, Apple has been expanding the list of US states and territories that support IDs in Apple Wallet. After adding Montana last month, North Dakota is now the latest to join. But what does it do? The list of places that actually accept Apple Wallet’s digital ID rather than the physical ID can vary wildly, and some states, like Montana, still recommend users carry their physical IDs regardless. Still, Apple notes that digital IDs can be used at TSA checkpoints in certain air

Writing Memory Safe JIT Compilers

Professor Yoshihiko Futamura You might not have encountered Futamura projections or partial evaluation before, so what is this strange sounding thing? The core idea is to automatically transform the code of your interpreter to create individual JIT compiled user methods. Instead of needing to carefully implement the language semantics in two places (interpreter and hand-crafted JIT), it’s sufficient to implement it just once. As the interpreter is memory safe and the transform preserves interp

SpaceX Wants to Fly Its Gigantic Starship Directly Over Florida

SpaceX is inching closer to sending its Starship rocket into low Earth orbit. A newly proposed flight path for the upper stage would see it fly across Florida skies—an unusual route that would seriously disrupt air traffic and raise the risk of debris falling onto populated areas below. The Federal Aviation Administration (FAA) is reviewing SpaceX’s request for new launch and reentry flight paths that would see its upper-stage Starship rocket crossing over Florida as it makes its way toward spa

I thought my iPhone 17 Pro Max camera couldn't get better - then I found this accessory

Follow ZDNET: Add us as a preferred source on Google. Today's smartphone cameras are so good that you can be a content creator without spending thousands on a dedicated camera. The optical image stabilization they have is also very good, but you can capture more creative shots and shoot in more challenging conditions with a smartphone gimbal.

PlayStation’s New Portable Gaming Speakers Could Be Really Good, If They Don’t Cost a Fortune

Sony has been on a roll lately with lots of gaming peripherals (including the Inzone H9 II gaming headset that may actually justify its big price tag), and it’s apparently not ready to stop just yet. PlayStation just announced its Pulse Elevate wireless speakers, which support PC, Mac, PlayStation 5, and the PlayStation Portal, and they may potentially be useful for anyone who doesn’t love constantly wearing a headset. Inside the Pulse Elevate, Sony says it’s including “studio-inspired planar m

The Beginning of My Programming Journey (2022)

Let’s start at the very beginning (A very good place to start) I wanted to get into programming or something programming-adjacent, perhaps using my enjoyment of teaching and helping people create things. I had a few ideas for apps, so I thought I’d begin my journey working toward making an app that would be useful to my interests. My exploration of programming would be in the off hours of my 40hr/week job. The closest thing to programming experience I have is reading half a chapter of Learning

Video models are zero-shot learners and reasoners

Abstract The remarkable zero-shot capabilities of Large Language Models (LLMs) have propelled natural language processing from task-specific models to unified, generalist foundation models. This transformation emerged from simple primitives: large, generative models trained on web-scale data. Curiously, the same primitives apply to today's generative video models. Could video models be on a trajectory towards general-purpose vision understanding, much like LLMs developed general-purpose languag

Amazon is bringing back Rick Moranis for the Spaceballs sequel

Amazon MGM Studios is working on a Spaceballs sequel, and a new cast photo confirms that Rick Moranis will be back after a decades-long break from live-action films to reprise his role as Dark Helmet. Moranis’ last live-action movie was Honey, We Shrunk Ourselves, released in 1997, and

Juicebox raises $30M from Sequoia to revolutionize hiring with LLM-powered search

For years, recruiters used machine learning to find potential hires by searching for keywords in resumes and LinkedIn profiles. Although this method helps to narrow the candidate pool, recruiters still have to manually review each profile to determine the best fit for the job. David Paffenholz (pictured left) and Ishan Gupta, then just 22 and 19, realized that LLMs could find talent faster and more efficiently. They built Juicebox, an AI-powered search engine that uses natural language to analy

Threads is developing a tool that lets you ‘tag’ its algorithm to configure your feed

Instagram is experimenting with bringing tools to control your own algorithm to Threads, its X rival. The feature was uncovered while in development by reverse engineer Alessandro Paluzzi, who discovered the code and told TechCrunch it’s related to the algorithm configuration tools that are also coming to Instagram. When contacted, Instagram confirmed the product is still an internal prototype for the time being and is not currently being tested with users. However, the Instagram account being

Starpath bets on mass-produced, space-rated solar

Ask Starpath CEO Saurav Shroff his thoughts on America’s space priorities and he’ll say we’re “one order of magnitude high on cost and one order of magnitude low on ambition.” Starpath’s answer, at least to part of the problem, is ultra-low cost space power, which is generated by solar panels. Starpath’s new space-rated solar panel business kicked off sales in the U.S. on September 25 with an eyebrow-raising pitch. The company says its solar panels, called “Starlight,” are priced around 10 tim

The best instant cameras for 2025

Instant cameras are popular for one simple reason: they’re fun. You can bring one to a party or event and capture a spontaneous moment, then after a couple of minutes, everyone can enjoy a physical photo instead of staring at a phone screen. The quality isn’t perfect, but those snaps have a nostalgic quality that people love. Buying one can be tricky though — you need to consider factors like price, film size, photo quality and more. Plus, there are a lot of models to choose from. This guide

The Theatre of Pull Requests and Code Review

The Theatre of Pull Requests and Code Review Meks McClure · September 23, 2025 I recently attended the Goatmire Elixir Conf and one of the standout talks for me was Saša Jurić's "Tell Me a Story".

John Boyega Says He Would’ve Had Very Different Ideas for the ‘Star Wars’ Sequels If He Was Producing Them

Few blockbuster franchises inspire as much debate and discourse as Star Wars, and it’s also the rare series that invites not just fans and critics to speak out, but also the people who have starred in its shows and movies. John Boyega, who played Finn across the sequel trilogy, hasn’t been shy about holding back, whether it’s his opinions on “Reylo” or how the fandom treats Star Wars‘ Black characters, to name two recent topics. And though The Rise of Skywalker hit theaters in 2019, it feels li

Jessica Chastain says she and Apple are ‘not aligned’ on decision to halt The Savant

In the last five years since we’ve been making the show, we’ve seen an unfortunate amount of violence in the United States: the kidnapping attempt on Michigan Governor Gretchen Whitmer; the January 6th attack on the Capitol; the assassination attempts on President Trump; the political assassinations of Democratic representatives in Minnesota; the attack on Speaker Pelosi’s husband; the assassination of conservative commentator Charlie Kirk; the recent shooting at an ABC affiliate station in Cali
