How to clear your iPhone cache (and why you should do it before updating to iOS 26)

What is cache? Cache -- or browser cache -- is the temporary storage of website files. So, things like images, scripts, and cookies that your browser saves on your phone to make pages load faster the next time you visit. Also: How to clear your Android phone's cache and make it feel like new Over time, though, those files can add up, taking a large bite out of your device storage and slowing things down.

Play Store search tab pops with color in latest Material 3 Expressive refresh

Edgar Cervantes / Android Authority TL;DR The Play Store is getting a taste of Google’s Material 3 Expressive design language with colorful new icons in the search tab. The new icons make search shortcuts more vibrant and easier to tell apart at a glance. The update was spotted on version 46.5.19 of the Play Store app and seems to be a server-side change. Google is rolling out a colorful and visually appealing update to the Play Store’s search tab. The tab now features colorful new icons ins

Foundations of Computer Vision (2024)

Foundations of Computer Vision Preface Dedicated to all the pixels. About this Book This book covers foundational topics within computer vision, with an image processing and machine learning perspective. We want to build the reader’s intuition and so we include many visualizations. The audience is undergraduate and graduate students who are entering the field, but we hope experienced practitioners will find the book valuable as well. Our initial goal was to write a large book that provided a g

First 2D, non-silicon computer developed

The team used metal-organic chemical vapor deposition (MOCVD) — a fabrication process that involves vaporizing ingredients, forcing a chemical reaction and depositing the products onto a substrate — to grow large sheets of molybdenum disulfide and tungsten diselenide and fabricate over 1,000 of each type of transistor. By carefully tuning the device fabrication and post-processing steps, they were able to adjust the threshold voltages of both n- and p-type transistors, enabling the construction

Scientists Discover Startling Trick to Defeat Insomnia

Image by Getty / Futurism Studies Insomnia is a curse we wouldn't wish on our worst enemy — and scientists have discovered a startlingly simple lifestyle change that appears to be very statistically effective at preventing it. In a new study published in the journal Sleep Health, researchers from Columbia and the University of Chicago report that eating a full day's serving worth of fruits and vegetables strongly appears to help people sleep more soundly throughout the night. Interrupted slee

ChatGPT Search gets an upgrade as OpenAI takes aim at Google

On June 13, OpenAI began rolling out a new ChatGPT Search update to improve quality as the AI startup challenges Google’s dominance. ChatGPT Search has been around for about a year and allows users to search the web more effectively than Google. It tries to summarize content from websites to provide quick answers and includes links to sources so you can fact-check everything. “This blends the benefits of a natural language interface with the value of up-to-date sports scores, news, stock quot

Tiny-diffusion: A minimal implementation of probabilistic diffusion models

A minimal PyTorch implementation of probabilistic diffusion models for 2D datasets. Get started by running python ddpm.py -h to explore the available options for training. Forward process A visualization of the forward diffusion process being applied to a dataset of one thousand 2D points.

'Shark Week' Comes Early as 'Jaws' Turns 50. Here's Where to Watch All the Movies

Somehow, five decades have passed since Steven Spielberg's Jaws chewed up the big screen. Turning the big Five-Oh is a big deal, so it's time to celebrate. The iconic movie, based on Peter Benchley's novel of the same name, took style notes from Hitchcock and the grindhouse movies of the era and became the first-ever summer blockbuster. Jaws isn't a complicated movie: It tells the story of a vengeful shark and the tourist beach town of Amity Island, which it decided to terrorize. The movie sta

Alexa von Tobel has high hopes for ‘fintech 3.0’

It’s been 10 years since Alexa von Tobel sold her financial planning startup Learnvest to Northwestern Mutual for $250 million. Since then, von Tobel became Northwestern Mutual’s first chief digital officer, then chief innovation officer, before launching an early-stage venture firm of her own, Inspired Capital, with former U.S. Secretary of Commerce Penny Pritzker. She’s also a New York Times bestelling author, and she’s about to launch a new interview podcast, “Inspired with Alexa von Tobel.”

Q-learning is not yet scalable

Does RL scale? Over the past few years, we've seen that next-token prediction scales, denoising diffusion scales, contrastive learning scales, and so on, all the way to the point where we can train models with billions of parameters with a scalable objective that can eat up as much data as we can throw at it. Then, what about reinforcement learning (RL)? Does RL also scale like all the other objectives? Apparently, it does. In 2016, RL achieved superhuman-level performance in games like Go and C

So... You Want to Become a Penetration Tester?

Cybersecurity is a rapidly growing and evolving field with a wide range of subfields and specializations. One of these is penetration testing, a discipline within what's known as "red teaming," which seeks to actively find and exploit vulnerabilities within computer systems (with permission, of course). It's an exciting and rewarding career, and I'll show you how to become a penetration tester. Before I continue, however, let me be transparent about my own experience. While I have about three

Google Search uses AI-generated podcast hosts to answer your questions

Instead of digging through all the top search results, you can now ask Google Search to give you a comprehensive AI-generated summary with its Audio Overviews feature. The AI feature uses Google Gemini models to create a short audio clip that sounds like a conversational podcast with two hosts. It's not ideal for your basic search queries like finding out when Father's Day is, but it's helpful if you want an in-depth and hands-free response to the history and significance of Flag Day. The Audio

Neanderthals Spread Across Asia With Surprising Speed—and Now We Know How

Neanderthals and modern humans split from a common ancestor around 500,000 years ago, with Neanderthals leaving Africa for Europe and Asia long before modern humans joined them hundreds of thousands of years later. There, Neanderthals dispersed as far as Spain and Siberia. Our prehistoric cousins likely first reached Asia around 190,000 to 130,000 years ago, with another substantial migration to Central and Eastern Eurasia likely between 120,000 and 60,000 years ago. But how did they get there?

ChatGPT Glossary: 52 AI Terms Everyone Should Know

Last fifty years of integer linear programming: Recent practical advances

Mixed-integer linear programming (MILP) has become a cornerstone of operations research. This is driven by the enhanced efficiency of modern solvers, which can today find globally optimal solutions within seconds for problems that were out of reach a decade ago. The versatility of these solvers allowed successful applications in many areas, such as transportation, logistics, supply chain management, revenue management, finance, telecommunications, and manufacturing. Despite the impressive succes

How the Alzheimer's Research Scandal Set Back Treatment 16 Years (2022)

In 2006, a landmark study in Nature identified a possible cause of Alzheimer’s disease. For almost 16 years, this study influenced how scientists approached Alzheimer’s and how major research grants were given. But in the summer of 2022, the editors of Nature issued a chilling disclaimer. There was concern regarding the images that accompanied the article. An investigation was underway, and readers were urged to “use caution” when relying on the results. A whistleblower had come forward and sa

How a Cyberattack at a Company You've Never Heard of Nearly Derailed My Anniversary Carrot Cake

Every year since we got married, my husband and I have celebrated our anniversary with a carrot cake. Some years it was from the amazing bakery in our old neighborhood, while others it was a questionably fresh effort picked up at a train station shop on the way home from the office, but often I would bake my own. The funny thing is, neither of us really likes carrot cake. It just somehow ended up being the top layer of our wedding cake, so we have one every year. That's tradition for you. This
