A 20-Year-Old Algorithm Can Help Us Understand Transformer Embeddings

Suppose we ask an LLM: “Can you tell me about Java?” What “Java” is the model thinking about? The programming language or the Indonesian island? To answer this question, we can try to understand what is going on inside the model. Specifically, we want to represent the model’s internal states in a human-interpretable way by finding the concepts that the model is thinking about. One approach to this problem is to phrase it as a dictionary learning problem, in which we try to decompose complex emb

I'm a Runner with Over 15 Years of Running Experience. These Are the Best Treadmills of 2025

The first thing I noticed about the NordicTrack Commercial 2450, NordicTrack's newest addition to its commercial treadmill series, is the touchscreen. It has a 22-inch HD touchscreen that resembles a desktop computer screen, so it's huge. It also tilts and pivots so you can adjust it for different uses, like if you want to take workout classes on the floor. The treadmill itself is also on the bigger side since it's a commercial treadmill, but it does fold up using its easylift assist feature, so

Tesla could have avoided that $242.5M Autopilot verdict, filings show

Months before a jury awarded a $242.5 million verdict against Tesla over its culpability in a 2019 fatal crash, the automaker had a chance to settle for $60 million. Instead, Tesla rejected that offer, according to new legal filings that were first reported by Reuters. The settlement proposal, which was made in May, was disclosed in a filing that requested Tesla cover legal fees for the plaintiffs in the case. Earlier this month, a jury in federal court in Miami found Tesla partly to blame f

Can AI Predict Powerball Numbers?

With the Powerball ballooning to $650 million after Wednesday’s drawing, hopeful players have been asking: Is winning the lottery a matter of luck or something that science and artificial intelligence can predict? Three students at the University of Salento in southern Italy say that science wins out. They say they used AI to analyze patterns from past draws to predict future winning numbers. Their experimental approach resulted in a €43,000 jackpot in April, which now has people wondering if

‘Skibidi,’ ‘Tradwife,’ and 6,000 Other New Words Are in the Dictionary Now

Before you roll your eyes at the Gen Alpha in your life for using made-up words, you might want to check the latest update to the dictionary. Cambridge University announced that its most recent revisions to the Cambridge Dictionary add 6,000 new words, including a slew of internet-pilled ones like skibidi, tradwife, and delulu. “It’s not every day you get to see words like skibidi and delulu make their way into the Cambridge Dictionary. We only add words where we think they’ll have staying powe

Aqua Voice shows just how good Mac dictation could be if Apple really tried

I’m a big fan of dictation and voice commands. The latter are the most common way for me to control my smart home, and I dictate a lot of my messages and other short pieces of text. Apple’s built-in dictation features have certainly improved over the years, but trying out the third-party app Aqua Voice shows just how much better it could be if Apple really tried. Indeed, I actually wrote the entirety of this piece using Aqua Voice dictation … Perhaps it’s the fact that I work from home, or jus

A spellchecker used to be a major feat of software engineering (2008)

A Spellchecker Used to Be a Major Feat of Software Engineering Here's the situation: it's 1984, and you're assigned to write the spellchecker for a new MS-DOS word processor. Some users, but not many, will have 640K of memory in their PCs. You need to support systems with as little as 256K. That's a quarter megabyte to contain the word processor, the document being edited, and the memory needed by the operating system. Oh, and the spellchecker. For reference, on my MacBook, the standard dictio

StarDict sends X11 clipboard to remote servers

StarDict sends X11 clipboard to remote servers [LWN subscriber-only content] StarDict is a GPLv3-licensed cross-platform dictionary application. It includes dictionaries for a number of languages, and has a rich plugin ecosystem. It also has a glaring security problem: while running on X11, using Debian's default configuration, it will send a user's text selections over unencrypted HTTP to two remote servers. On August 4, Vincent Lefevre reported the problem to the oss-security mailing list an

Earth Is Spinning Weirdly Faster, Making This Tuesday One of the Shortest Days Ever

The Earth's rotation is randomly speeding up, and nobody is quite sure why. These speed ups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also haven't gone unnoticed by science. Aug. 5 is the next date when the Earth's rotation is expected to speed up, shortening the day by between 1.25 and 1.51 milliseconds. According to TimeandDate, the current prediction is set by the International Earth Rotation and Reference Systems Service and t

Tesla partly liable in Florida Autopilot trial, jury awards $329M in damages

A jury in federal court in Miami has found Tesla partly to blame for a fatal 2019 crash that involved the use of the company’s Autopilot driver assistance system. The jury awarded the plaintiffs $329 million in punitive and compensatory damages. Neither the driver of the car nor the Autopilot system braked in time to avoid going through an intersection, where the car struck an SUV and killed a pedestrian. The jury assigned the driver two-thirds of the blame, and attributed one-third to Tesla. (

Show HN: A word of the day that doesn't suck

I’ve long thought that the Word of the Day was a wasted genre. The goal should be to give you words you can use; to enrich your understanding of words you already know; or at least to use words to tell you something neat about the world. Instead, what you usually get is words that will never be used in conversation, held up as curios. Some examples from Dictionary.com’s daily email: thewless, balladmonger, vagility, contextomy. These words are... not useful. I’ve always thought I could do bett

Doctors Say Ozempic Is Wildly Effective at Helping Addicts Beat Cravings

Image by Getty / Futurism Rx/Medicines Drugs like Ozempic and Wegovy already had a lengthening laundry list of physical health benefits, but now they're increasingly showing promise as treatments for neuropsychological conditions as well. Specifically, one of the most intriguing potential uses for these GLP-1 drugs is in addiction treatment, for vices ranging from alcohol to opioids to stimulants to gambling. And it's gaining momentum: as STAT News reports, one posh Pennsylvania rehabilitation

Dictionary.com “devastated” paid users by abruptly deleting saved words lists

Logophiles are "devastated" after Dictionary.com deleted their logs of favorited words that they carefully crafted for years. The company deleted all accounts, as well as the only ways to use Dictionary.com without seeing ads —even if you previously paid for an ad-free experience. Dictionary.com offers a free dictionary through its website and free Android and iOS apps. It used to offer paid-for mobile apps, called Dictionary.com Pro, that let users set up accounts, use the app without ads, and

Here's How to Turn Off Some Annoying iPhone Texting Features

Texting is one of the easiest ways to stay in touch with friends and family, and if you can't find the right words to use in a text, you can always use an emoji. But you might find some texting features on iPhone to be downright annoying. Some of the biggest culprits include autocorrect and predictive texting. Autocorrect can cut down on the number of typos when you're typing, and predictive texting can make it easy to write a full message in a few quick taps. But when I use these features, mor

The ITTAGE indirect branch predictor

While investigating the performance of the new Python 3.14 tail-calling interpreter, I learned (via this very informative comment from Sam Gross) new (to me) piece of performance trivia: Modern CPUs mostly no longer struggle to predict the bytecode-dispatch indirect jump inside a “conventional” bytecode interpreter loop. In steady-state, assuming the bytecode itself is reasonable stable, modern CPUs achieve very high accuracy predicting the dispatch, even for “vanilla” while / switch -style inte

Compression Dictionary Transport

Algorithms like Brotli compression and Zstandard compression achieve even greater efficiency by allowing the use of dictionaries of commonly encountered strings, so you don't need any copies of them in the compressed resource. These algorithms ship with a predefined default dictionary that is used when compressing HTTP responses. Compression Dictionary Transport builds on this by enabling you to provide your own dictionary which is especially applicable to a particular set of resources. The com

US judge rules Huawei must answer criminal charges about alleged Iran deal

A US judge has ruled that Huawei must stand trial following a 16-count indictment from 2019 accusing the Chinese telecommunications company of trying to steal trade secrets from its US rivals and selling surveillance equipment to Iran despite trade sanctions, according to a report by Reuters . A trial is currently set for May 4, 2026. US District Judge Ann Donnelly found sufficient evidence in the indictment to refute the company's bid for dismissal. In a 52-page decision, the Brooklyn judge ru

Scientists Scanned the Brains of Hardcore Gooners and Found Something Ominous

In a new study published in the journal Frontiers in Human Neuroscience, researchers at the Chengdu Medical College in China found that people who watch a lot of pornography had lower cognitive performance and showed signs of neurological arousal akin to opioid addiction. It's new data in a swirling debate over whether watchi

Google DeepMind is sharing its AI forecasts with the National Weather Service

It launched a new website where you can see its predictions. Here's an AI-government collaboration of a less… unsettling variety than some. Google DeepMind is teaming up with the National Hurricane Center (NHC) for tropical cyclone season. The AI research lab claims it can predict hurricane paths and intensities with at least the same accuracy as traditional methods. NHC forecasters have already begun using DeepMind's AI model. Google says they're designed to support, not replace, human NHC fo

Don’t forget: Three-button navigation is getting a much-needed upgrade with Android 16

TL;DR Android 16 extends predictive back navigation to three-button navigation. You can now see a preview of the previous screen by long-pressing the back button. Additionally, apps targeting Android 16 will have predictive back system animations by default. After debuting the predictive back navigation as a developer option in Android 13, Google finally enabled it by default in last year’s release. The feature previously only worked when using gesture-based navigation, but Google is extendin
