From Point Clouds to Photorealism: How PRoGS Advances the State of Neural Rendering

What if a real-time automated decision-making process needs a computer vision system to produce photorealistic visuals in a mere fraction of a second? In many cases, this requires too much computational power — if it’s even possible at all. When computer vision uses 3D Gaussian splatting (3DGS), it provides a photorealistic image, but the process takes far too long. For more on this topic, see our article on computer vision for disaster responses. This article discusses a new approach, Progress

On The Meaning of Ritual

The Book of Rites, also known as the Classic of Ritual. The Way of the former kings consists in exalting ren. One must cleave to what is central in carrying it out. What do I mean by "what is central"? I say: it is ritual and yi (8.99). The Confucian moral order is grounded in ren (仁), yi (義), and ritual (禮, li). Ren is humaneness, empathy, and magnanimous compassion. Yi is righteousness, firmness of will, and principles-based justice. Ren is the duty to care and provide for those in your ch

Tuesday Telescope: Webb and Hubble team up to reveal spectacular star clusters

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder. Open clusters of stars—which consist of dozens up to a few thousand stars—are an interesting tool for astronomers to study the Universe. T

Elon Musk Calls the U.S. Dollar ‘Hopeless,’ Says His America Party Will Embrace Bitcoin

As details about his new political venture begin to emerge, Elon Musk has confirmed that the “America Party” will embrace Bitcoin, a move that solidifies the party’s anti-establishment and tech-centric identity. The world’s richest man made the revelation on his social media platform, X, signaling a potential new frontier for cryptocurrency in American politics. The exchange unfolded after Musk positioned his new party as a home for centrists and voters disillusioned with the traditional two-pa

Why English doesn't use accents

Portrait of Jean Miélot (after 1456), Jean le Tavernier Canterbury, AD 1105 The cold of the stone floor in the scriptorium creeps up through Godwin’s boots. He pays it no mind. Before him lies a copy of the Chronicle, just arrived from the old capital of Winchester. In it is written the history of the English people. His people. Today, his job is to make another copy. No difficult task for Godwin, or any monk. But Abbot Robert will want to inspect the work before vespers. Abbot Robert. A No

Optimizing Tool Selection for LLM Workflows with Differentiable Programming

Modern agentic architectures rely heavily on chaining LLM calls. A typical pattern looks like: Use an LLM to decide which tool to invoke Call the tool (e.g. search, calculator, API) Use another LLM call to interpret the result and generate a final response This structure is easy to reason about, simple to prototype, and generalizes well. But it scales poorly. Each LLM call incurs latency, cost, and token overhead. More subtly, it compounds context: every step includes not only the original q

N-Back – A Minimal, Adaptive Dual N-Back Game for Brain Training

Playing the N-Back test is straightforward but requires focused attention. Watch the 3x3 grid as blue squares appear in different positions. Your task is to remember the sequence and identify when the current position matches the one from N steps ago. For a 2-Back test (the standard version), you need to determine if the current square's position matches the position from 2 steps earlier. Click 'Match' or press the spacebar when you detect a match, or click 'No Match' or press 'N' when there's

A rare look inside the durability lab where Apple tortures its products

Apple puts its products through a lot of tests during the development process, intended to ensure they have a long and reliable life even in challenging conditions. The company tests at least 10,000 iPhones prior to launch in an attempt to cover all the bases. It’s not often the iPhone maker lets outsiders into its labs, but Apple invited some of those attending WWDC 2025 to visit one to see for themselves the conditions it expects its gadgets to survive … To be clear, it’s not the first time

I want to leave tech: what do I do?

Let’s say you’re working in tech and you have a technical role: you’re a programmer, a graphic or UI/UX designer, a sysadmin, maybe even a product manager. Let’s say you want to leave, change career, and do something more meaningful with your skills. Your motivations may vary: you feel the tech industry produces nothing of value, or maybe you have the legitimate suspicion that what you build helps bomb innocent people somewhere. You might want to leave because of the individualistic culture tha

Leaks hint at Operator-like tool in ChatGPT ahead of GPT-5 launch

A few new code references in the ChatGPT web app and Android point to an Operator-like tool in GPT's chain of thoughts. As spotted by Tibor on X, the Android beta has strings like “click,” “drag,” “type,” and even “terminal feed,” which seem to suggest that ChatGPT could soon call a remote browser or sandboxed environment (Operator?). For those unaware, OpenAI already has Operator, which uses an AI agent to navigate a remote browser session and execute tasks for you. These references suggest

The Stars of ‘Superman’ Claim to Have No Knowledge of Their DC Futures

We don’t know much about the future of James Gunn’s DC Universe, but one thing seems all but certain: Superman will be back. He’s the universe’s most powerful metahuman, after all, and one of the most famous, popular characters on the DC roster. Clearly, he’s going to have a role to play in whatever is coming next. And, along with Superman, come a few of his friends and foes. People like Lois Lane and Lex Luthor. So it kind of goes without saying that David Corenswet, Rachel Brosnahan, and Nich

Tools: Code Is All You Need

Tools: Code Is All You Need If you've been following me on Twitter, you know I'm not a big fan of MCP right now. It's not that I dislike the idea; I just haven't found it to work as advertised. In my view, MCP suffers from two major flaws: It isn’t truly composable. Most composition happens through inference. It demands too much context. You must supply significant upfront input, and every tool invocation consumes even more context than simply writing and running code. A quick experiment make

What James Gunn’s ‘Superman’ Tells Us About the Future of the DC Universe

It’s been years since James Gunn and Peter Safran first announced their plans for the future of the DC Universe. In that time, plans have changed slightly, and work is ongoing, but, with one exception, we have yet to see exactly how things are going to play out. That changes July 11 with the release of Superman. Not only is the film our first introduction to this brand-new, reimagined version of Superman, it’s our first look at what Gunn and Safran’s DC Universe looks like on the big screen. Sp

AT&T rolls out Wireless Account Lock protection to curb the SIM-swap scourge

AT&T is rolling out a protection that prevents unauthorized changes to mobile accounts as the carrier attempts to fight a costly form of account hijacking that occurs when a scammer swaps out the SIM card belonging to the account holder. The technique, known as SIM swapping or port-out fraud, has been a scourge that has vexed wireless carriers and their millions of subscribers for years. An indictment filed last year by federal prosecutors alleged that a single SIM swap scheme netted $400 milli

Medical groups warn Senate budget bill will create dystopian health care system

Medical organizations are blasting the Senate's budget bill in the wake of its narrow passage Tuesday, warning of the dystopian health care system that will arise from the $1.1 trillion in cuts to Medicaid and other federal health programs if it is passed into law. The bill has moved back to the House for a vote on the Senate's changes. Over the weekend, an analysis from the Congressional Budget Office estimated that 11.8 million people would lose their health insurance over the next decade due

How generative AI could help make construction sites safer

To combat the shortcuts and risk-taking, Lorenzo is working on a tool for the San Francisco–based company DroneDeploy, which sells software that creates daily digital models of work progress from videos and images, known in the trade as “reality capture.” The tool, called Safety AI, analyzes each day’s reality capture imagery and flags conditions that violate Occupational Safety and Health Administration (OSHA) rules, with what he claims is 95% accuracy. That means that for any safety risk the

Spain and Brazil push global action to tax the super-rich and curb inequality

Presented during the UN’s 4th International Conference on Financing for Development – taking place this week in Sevilla, Spain – the proposal highlights a growing problem: the richest individuals often contribute less to public finances than ordinary taxpayers, thanks to lower effective tax rates and legal loopholes. “Our countries need more and more public revenues to meet their needs. Inequality is a problem everywhere and the richest pay less than the middle class – even less than lower-inco

Aesop in Words of One Syllable

In the 19th Century, British and American children’s literature evolved from puritanical moral and religious instruction to delightfully imaginative tales meant to awaken a sense of wonder. But morality and imagination could certainly thrive together. Æsop’s Fables in Words of One Syllable is an excellent example of this. The ancient Greek storyteller Aesop may or may not have existed, and he may or may not have written the hundreds of morality tales attributed to him. Yet his stories have been

GOP budget bill poised to crush renewable energy in the US

Far from the front lines of the climate crisis, 100 men and women in air-conditioned offices, 61 of them millionaires, are making decisions that could increase United States carbon dioxide emissions, and the warming of the climate they are driving, for decades to come. In the latest political wrangle over energy and climate policy, a group of Republican senators over the weekend added provisions to the U.S. federal budget bill that, as currently written, would end clean energy tax credits at th
