Superman Saving a Squirrel Was Cut Out of the Movie, but James Gunn Put It Back In

There are plenty of weird and unexpected moments in James Gunn’s Superman, but one of the most unexpected has to be when he saves a squirrel in the middle of a giant battle. Not a human, not a group of animals, but a single, solitary squirrel. It speaks to the character’s kindness and respect for all life in a fun, quirky way, but apparently not everyone liked it. “It was probably the second- or third-most hotly debated moment in the movie,” Gunn said in a wide-ranging interview with Rolling St

OpenAI jumps gun on International Math Olympiad gold medal announcement

On Saturday, OpenAI researcher Alexander Wei announced that a new AI language model the company is researching has achieved gold medal-level performance on the International Mathematical Olympiad (IMO), matching a standard that fewer than 9 percent of human contestants reach each year. The announcement came despite an embargo request from IMO organizers asking AI companies to wait until July 28 to share their results. The experimental model reportedly tackled the contest's six proof-based probl

Grok’s AI companions drove downloads, but its latest model is the one making money

Grok’s raunchy, unfiltered AI companions may be making headlines for their unhinged and often NSFW responses, but it’s Grok 4, xAI’s latest model, that’s been driving the app’s revenue of late. Elon Musk’s xAI launched Grok 4 late on July 9, and by Friday, July 11, Grok’s gross revenue on iOS had jumped a whopping 325% to $419,000, up from $99,000 the day before the Grok 4 launch, according to app intelligence firm Appfigures.

I’m Revisiting All of the Naked Gun Movies Before the Reboot. Here’s How You Can, Too

Growing up, the Naked Gun series was a staple in my household. I rented the movies so regularly that my parents gave me the trilogy on DVD for Christmas one year. These days, it’s easier to revisit old favorites through streaming services, but that box set still sits proudly in my media drawers. Even today, I find the straight-faced humor gut-bustlingly hilarious. While headliner Leslie Nielsen starred in some serious films like Forbidden Planet, The Poseidon Adventure and Prom Night, showcasing

Java was not underhyped in 1997 (2021)

Java Criminally Underhyped? Not Back in 1997. Earlier today, a fun little moment of Twitter serendipity alerted me to an article by Jackson Roberts, a computer science student at the University of Colorado, entitled “Java is criminally underhyped”. It’s a really interesting article, and Jackson’s observations correlate with a lot of my own thinking about languages and platforms, although I am squarely in the .NET / CLR camp on that particular front. But Jackson ends his article: I am curious

LLM architecture comparison

It has been seven years since the original GPT architecture was developed. At first glance, looking back at GPT-2 (2019) and forward to DeepSeek-V3 and Llama 4 (2024-2025), one might be surprised at how structurally similar these models still are. Sure, positional embeddings have evolved from absolute to rotational (RoPE), Multi-Head Attention has largely given way to Grouped-Query Attention, and the more efficient SwiGLU has replaced activation functions like GELU. But beneath these minor refi

James Gunn Talks Future Superman Plans, Dropping Henry Cavill

James Gunn’s spent the past few weeks talking about why he agreed to do Superman, and he’s also taking time to address the awkward part: agreeing to do it at the apparent expense of Henry Cavill’s superhero comeback. In 2022, the mid-credits scene for Black Adam none too subtly declared Cavill’s return and his team up (or fight) with Dwayne Johnson’s thunderous antihero. Nothing came of that, however, because as Gunn explained in a recent Happy Sad Confused episode, it was “never part of the eq

The Hunt for a Fundamental Theory of Quantum Gravity

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally interwoven threads of space and time seem to stop short. These mysterious points are known as singularities. Singularities are predictions of Albert Einstein’s general theory of relativity. According to this theory, clumps of matter o

Trying Guix: A Nixer's impressions

Trying Guix: A Nixer's Impressions People occasionally ask me how I think Guix compares to Nix. Let me set the stage: I've been using Nix for many years, have large projects using Nix, used to be very active in the Nix community, and even wrote multiple Nix language interpreters, so I'd say that I'm at least fairly comfortable with Nix. I'm also one of those people who live in Emacs. I'm no stranger to Lisps (although my experience with Scheme is limited) and am very fond of them. It feels nat

Benchmark in talks to lead Series A for Greptile, valuing AI-code reviewer at $180M, sources say

Greptile, an AI-powered code review startup, is in the process of raising a Series A. Sources familiar with the deal tell TechCrunch it’s for $30 million at a $180 million valuation led by Benchmark partner Eric Vishria. But one person says that the deal hasn’t closed and terms may change. Founded by Dasksh Gupta after he graduated from Georgia Tech in 2023, the startup went through Y Combinator in the winter of 2024 cohort, and raised a $4 million seed round led by Initialized Capital after co

James Gunn and DC Haven’t Started Casting Wonder Woman… Yet

The holy trilogy of James Gunn’s DC Universe is slowly coming together. Part one, of course, is Superman, which is now in theaters. A Batman movie is being written (in addition to Matt Reeves’ new Batman movie), and, of late, there’s been lots of talk about Wonder Woman too. As co-president of DC Studios, Gunn recently confirmed a Wonder Woman script is being written, and subsequent rumors suggested the film was being fast-tracked. Well, that’s partially true, Gunn said. “It’s a priority, but I

Chinese hackers breached National Guard to steal network configurations

The Chinese state-sponsored hacking group known as Salt Typhoon breached and remained undetected in a U.S. Army National Guard network for nine months in 2024, stealing network configuration files and administrator credentials that could be used to compromise other government networks. Salt Typhoon is a Chinese state-sponsored hacking group that is believed to be affiliated with China's Ministry of State Security (MSS) intelligence agency. The hacking group has gained notoriety over the past tw

A New Geometry for Einstein's Theory of Relativity

Kunzinger and Sämann wanted to use their new way of estimating curvature to determine whether these singularity theorems would still be valid if they no longer assumed space-time is smooth. Would singularities persist even in rougher, more realistic-looking spaces? It’s important to find out if the smoothness condition can be waived, Sämann said, because doing so would bring the theorems closer to physical reality. After all, he added, “we believe non-smoothness is an inescapable part of the nat

Meta just poached two more AI researchers from Apple amid internal shakeup

Just days after hiring Ruoming Pang, who had led Apple’s foundation model efforts, Meta is reuniting him with two former colleagues from Cupertino. Engineers Mark Lee and Tom Gunter to reunite with their former boss from Cupertino As reported by Bloomberg, Mark Lee and Tom Gunter, both key members of Apple’s Foundation Models (AFM) group, are joining Meta’s Superintelligence Labs team: Lee was known as Pang’s first hire at Apple, while Gunter, who was a distinguished engineer at Apple, was re

Signs Your Gut Is Unhealthy and the 4 Ways to Restore It

Your gut health plays a significant role in your overall well-being. In fact, the trillions of microbes living in your gut, collectively known as the gut microbiome, serve as your body's internal environment. Many people have recently become obsessed with healing their gut to avoid embarrassing symptoms like bloating and/or flatulence. Consider your gut microbiome as "little pets living inside your intestinal tract," Cleveland Clinic microbiome expert Gail Cresci explains. These microbes help b

Roman dodecahedron: 12-sided object has baffled archaeologists for centuries

A dodecahedron was discovered in Lincoln in the U.K. in the summer of 2023. QUICK FACTS Name: Roman dodecahedron What it is: A 12-sided bronze object Where it is from: Northwestern provinces of the Roman Empire When it was made: Second to fourth centuries A.D. Roman dodecahedrons have baffled archaeologists since 1739, when the first example of the 12-sided bronze object was discovered in the English Midlands.

Analogue’s N64 clone is finally shipping, and there’s good news for pre-orders

TL;DR Analogue announced its N64 FPGA device is finally shipping in August. Released in pre-order in October 2024, the Analogue 3D faced nearly a year of delays. Pre-orders are not subject to additional tariff charges, with Analogue eating the cost. The Analogue 3D made huge waves when it was made available for pre-order in October 2024, promising to play classic N64 cartridges in full 4K over HDMI. The $250 pre-orders quickly sold out, and after nearly a year of waiting, Analogue has announc

Get the macOS Finder to Do Just About Anything by Typing Natural Language Commands

I'm genuinely not sure if large language models—often referred to as “AI” in shorthand—are the future of computing. But I also don't think chatbots are how people will use this technology in the years to come. Substage, an indie Mac application by developer Joseph Humfrey, is a simple app that points to a potential alternative—one that's useful right now. This application floats under every Finder window, meaning you see it only when you're browsing files in macOS. You can type English-languag

Mostly dead influential programming languages (2020)

The other day I read 20 most significant programming languages in history, a “preposterous table I just made up.” He certainly got preposterous right: he lists Go as “most significant” but not ALGOL, Smalltalk, or ML. He also leaves off Pascal because it’s “mostly dead”. Preposterous! That defeats the whole point of what “significant in history” means. So let’s talk about some “mostly dead” languages and why they matter so much. Disclaimer: Yeah not all of these are dead and not all of these a

What the Post-Credit Scenes for 'Superman' Mean for the Future of DC's Cinematic Universe

It's official -- James Gunn's new Superman movie is officially a blockbuster hit, earning $125 million in the US during its first weekend. If you're a fan of other Gunn movies like Suicide Squad or Guardians of the Galaxy, you'd best grab your tickets for this relaunch of this new DC Universe before they're all sold out. Superman stars Rachel Brosnahan as Lois Lane, Nicholas Hoult as Lex Luthor and David Corenswet as the Man of Steel. The movie isn't an origin story; it picks up when Superman i

Apple researchers taught an AI model to reason about app interfaces

A new Apple-backed study, in collaboration with Aalto University in Finland, introduces ILuvUI: a vision-language model trained to understand mobile app interfaces from screenshots and from natural language conversations. Here’s what that means, and how they did it. ILuvUI: an AI that outperformed the model it was based on In the paper, ILuvUI: Instruction-tuned LangUage-Vision modeling of UIs from Machine Conversations, the team tackles a long-standing challenge in human-computer interaction,

Krypto’s ‘Superman’ Spotlight Is Inspiring People to Adopt Their Own Superdog

While Warner Bros. Discovery celebrates the success of DC Studios’ Superman, the true winners from this past weekend’s blockbuster may have more in common with Krypto. The Superdog who stole the movie has inspired an uptick in pet adoption interest. According to dog-training app Woofz, “Google searches for ‘adopt a dog near me’ jumped up 513%” in the days after the James Gunn-directed film’s opening weekend, while “‘rescue dog adoption near me’ hit 163% in increase.” And it makes sense, as Gunn

You’re Gonna Be Waiting a While for the Return of ‘Last of Us’ or ‘Penguin’

Genre shows made a huge impact on today’s Emmy announcements, with Apple TV+’s Severance leading the charge for most-nominated title overall with recognition in 27 categories. But HBO’s The Penguin wasn’t far behind with 24, and though you might expect that to mean the studio would be actively working on more episodes—well, it’s complicated, given the show’s positioning within Matt Reeves‘ The Batman universe. Speaking to Variety, HBO and HBO Max CEO and content chairman Casey Bloys—who would s

Analogue says its delayed N64 remake console will start shipping next month

US tariffs continue to cause problems and supply issues in the gaming space. The latest to feel the effects is Analogue. The company announced today that its Analogue 3D, a modern remake of the Nintendo 64 console, will not start shipping until late August. Analogue noted that "last week's sudden tariffs" were the reason for this change. "We’re absorbing the costs—your preorder price stays the same. No additional charges," the company said in a post on X. This isn't the first time the highly a

We Can’t Get Enough of Jimmy Olsen in ‘Superman’

“What is going on with Jimmy Olsen?” I recently asked the stars of Superman. “What is it about that guy?” “He’s got rizz,” replied Rachel Brosnahan, who plays Olsen’s fellow reporter Lois Lane. “This is a true fact about Skyler Gisondo,” Clark Kent himself, David Corenswet, added about the Olsen actor. “Which I hope is appropriate to share. Sorry, Skyler… His testosterone is through the roof. Off the charts. True story. So of course, who is surprised that his Jimmy Olsen is pulling the kind of g
