Anatomy of a Python Loop

Learn Python loops the fun way by rolling dice, casting fireballs, and finally understanding what continue really does. Last time, when we built our little dice-rolling function, we learned how to package up logic into reusable blocks. One die roll at a time was cool… but any tabletop nerd knows the real action starts when you need to roll lots of dice. 3d6 for ability scores. 8d6 for a fireball spell. Or the cruel 10d10 your DM makes you roll when things go really sideways. So how do we te

Why You Should Be Using XSLT 3.0 (2017)

A look at the upcoming XSLT 3.0 release, and why it matters beyond the XML community Eighteen years ago, the originators of XML specification faced a problem: how to use the new language to generate a book-publishing format. What emerged were two new languages, the first for describing the various functional parts of a publication in XML called the XML Stylesheet Language Formatting Objects (ultimately XSL-FO) and the XML Stylesheet language (XSLT) for transforming XML-formatted content into th

The best audio editing software of 2025: Expert tested and reviewed

You have the quiet area, the top-quality microphone, excellent speakers, and a reliable recording platform -- but without the right audio editing software or Digital Audio Workstation (DAW) to back you, your new audio production might fall short. Many of us now expect clear, quality sound when we listen not only to songs, but also when we listen to podcasts, social media videos, YouTube content, film and TV shows, and marketing materials. Listeners -- and potential subscribers -- are far more l

Do the simplest thing that could possibly work

When designing software systems, do the simplest thing that could possibly work. It’s surprising how far you can take this piece of advice. I genuinely think you can do this all the time. You can follow this approach for fixing bugs, for maintaining existing systems, and for architecting new ones. A lot of engineers design by trying to think of the “ideal” system: something well-factored, near-infinitely scalable, elegantly distributed, and so on. I think this is entirely the wrong way to go a

Windows 11 KB5064081 update clears up CPU usage metrics in Task Manager

​​Microsoft has released the KB5064081 preview cumulative update for Windows 11 24H2, which includes thirty-six new features or changes, with many gradually rolling out. These updates include new Recall features and a new way of displaying CPU usage in Task Manager. The KB5064081 update is part of the company's optional non-security preview update schedule, which releases updates at the end of each month to test new fixes and features coming to the next month's Patch Tuesday. Unlike regular Pa

Wearable devices are sharing your private data - these are the 5 worst offenders

Sabrina Ortiz/ZDNET Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Several wearable devices are sharing user data. The worst offenders include Meta, Samsung, Xiaomi, and Huawei. Apple, Oura, and Whoop have some of the best data practices. Those shiny new Meta Ray-Bans might be uploading the media you're collecting to train its AI model, according to a new report by VPNMentor highlighting the data-sharing practices of the best and worst wearables. Meta and it

Starlink Puts the Last Nail in Burning Man’s Coffin

Whatever embers may still be left burning from the original spirit of Burning Man are holding on for dear life as Silicon Valley tries to put them out for good. The latest dagger delivered to the Bohemia turned billionaire LARPing event comes from above, as Elon Musk’s Starlink is now providing internet connection to those in attendance, according to the Wall Street Journal. A Burning Man regular named Kevin LeVezu, a photographer, runs a camp at the temporary city called iForgot. This year, he

Battlefield 6 dev apologizes for requiring Secure Boot to power anti-cheat tools

Earlier this month, EA announced that players in its Battlefield 6 open beta on PC would have to enable Secure Boot in their Windows OS and BIOS settings. That decision proved controversial among players who weren't able to get the finicky low-level security setting working on their machines and others who were unwilling to allow EA's anti-cheat tools to once again have kernel-level access to their systems. Now, Battlefield 6 technical director Christian Buhl is defending that requirement as so

Tesla denied having fatal crash data until a hacker found it

At the beginning of the month, Tesla was found partly liable in a wrongful death lawsuit involving the death of a pedestrian in Florida in 2019. The automaker—which could have settled the case for far less—claimed that it did not have the fatal crash's data. That's until a hacker was able to recover it from the crashed car, according to a report in The Washington Post. In the past, Tesla has been famously quick to offer up customer data stored on its servers to rebut claims made against the com

Best Washing Machines for Your Home in 2025

It's not always about the features that you most regularly use, but about having features available that you might sometimes need to use. If available features are driving your comparative shopping experience for washing machines, GE offers a top-tier, front-loading model with consistent customer satisfaction and just about every available add-on. While it is more expensive than the models listed above, it's less expensive than other models that offer as many features as it does. This washing m

Why AI Isn't Ready to Be a Real Coder

Artificial intelligence (AI) has transformed the coding sphere, with AI coding tools completing source code, correcting syntax errors, creating inline documentation, and understanding and answering questions about a codebase. As the technology advances beyond automating programming tasks, the idea of full autonomy looms large. Is AI ready to be a real coder? A new paper says not yet—and maps out exactly why. Researchers from Cornell University, MIT CSAIL, Stanford University, and UC Berkeley hi

Connecticut Man’s Case Believed to Be First Murder-Suicide Associated With AI Psychosis

A case of murder-suicide in Connecticut earlier this month is being identified as potentially the first homicide fueled by a mentally disturbed person’s use of generative artificial intelligence, according to a new report from the Wall Street Journal. Police in Greenwich, Connecticut, found Stein-Erik Soelberg, a 56-year-old tech industry veteran, and his 83-year-old mother, both dead in the home where they lived together on Aug. 5, according to the Greenwich Police Department. Soelberg killed

Microsoft and Uber alum raises $3M for YC-backed Munify, a neobank for the Egyptian diaspora

Khalid Ashmawy remembers the first time he wired money home while studying in Europe. He had just received his monthly stipend as a master’s student in Stuttgart and wanted to send part of it back to his family in Cairo. It was usually a slow and expensive process, he recalled. A $400 wire transfer, for instance, could cost $40 in fees and take three business days to arrive. Years later, while working at Microsoft and Uber in the U.S., and even after founding a startup, that experience hadn’t

Contrastive Representations for Temporal Reasoning

In classical AI, perception relies on learning spatial representations, while planning—temporal reasoning over action sequences—is typically achieved through search. We study whether such reasoning can instead emerge from representations that capture both spatial and temporal structure. We show that standard temporal contrastive learning, despite its popularity, often fails to capture temporal structure, due to reliance on spurious features. To address this, we introduce Contrastive Representati

Clues for Apple's iPhone 17 Event Point to More Than Thin Phones

The iPhone lineup will forever change on Sept. 9, as Apple's big "Awe Dropping" iPhone 17 event might reveal an ultra-thin model, nicknamed by many as "iPhone Air." Months of leaks, reports and rumors have analysts and pundits not only expecting a new, thinner iPhone in the 10 a.m. PT live-streamed presentation, but also new models of the Apple Watch Series 11 and AirPods Pro 3. Apple may have hidden clues in the art of the announcement. For this week's episode of One More Thing, embedded above

The AYN Odin 3 might solve the biggest problem with the Odin 2 Portal and Pocket 5

TL;DR AYN has revealed design renders for its upcoming Odin 3 gaming handheld. It looks like a mix between the Odin 2 Portal and Retroid Pocket 5, with an ergonomic grip. No specs have been revealed, but we should learn more soon. It’s been a few weeks since AYN first announced the follow-up to its flagship Odin 2, but the company has finally teased design renders in a 30-second YouTube video. It’s one of the year’s most anticipated releases, but the design itself is remarkably familiar. The

Google will throttle Pixel 10 charging, battery and that makes me upset

C. Scott Brown / Android Authority Google announced a mandatory Battery Health Assistance (BHA) feature for the Pixel 9a earlier this year. This feature essentially reduces the battery’s effective capacity and charging speeds as the cell ages, in the name of safety. This greatly concerned me, as the feature was optional for previously released Pixel phones. Now, Google has confirmed that this feature is also mandatory on the Pixel 10 series of phones. And this decision isn’t great at best and

Google Phone app’s Calling Cards are now rolling out widely: Here’s what you need to know

AssembleDebug / Android Authority TL;DR • Google’s “Calling Cards” feature is now widely rolling out in v188 of the Phone app, allowing Android users to personalize incoming/outgoing call screens with full-screen photos and styling options. Calling Cards differs from Apple’s Contact Posters in that it gives you full control over how each contact appears on your device — you set one card per contact manually. Alongside Calling Cards, the updated app introduces major UI changes, including a new

How to screenshot on Windows

Windows offers several built-in ways to take screenshots. Sure, you can just hit the Prt Scrn button on your keyboard to capture your entire screen, but if you want to screenshot a portion of your screen, a particular window, or you have multiple monitors there are other ways you can use Windows to achieve this. Whether you're using Windows 11 or a recent update to Windows 10, the tools remain largely consistent and reliable. This guide walks you through the most useful native screenshot method

Google’s working on making it easier to find calls you’ve recorded (APK teardown)

Ryan Haines / Android Authority TL;DR Google’s Phone app supports call recording in select areas. Earlier this year we saw the Phone app picking up new filters to sort through your call log. Now the app appears to be working on a filter to quickly display calls that have been recorded. Being able to easily record a voice call is exactly the sort of thing a smartphone should be useful for, but messy legal concerns keep the feature from being nearly as ubiquitous as it should be. Google’s got

Changing these 10 settings on my OnePlus phone gave it a big performance boost

Kerry Wan/ZDNET Follow ZDNET: Add us as a preferred source on Google. It's been agreed upon by the ZDNET team that the OnePlus 13 is this year's sleeper hit. At a starting price of $899, the flagship phone can compete against more expensive phones like the Pixel 10 Pro XL and Samsung Galaxy S25 Ultra. And we have OnePlus' clean yet highly customizable software experience to thank for that. Also: You can try Android 16's new lock screen widgets - if you have one of these phones If you switche

We Asked Dentists: What's the Best Whitening Toothpaste of 2025?

Why we like it: Colgate Optic White Pro Series toothpaste is one whitening toothpaste that Dr. Fatima Khan, a dentist in Houston, Texas, recommends. Some of her reasons for recommending it include its trusted brand name and its 5% hydrogen peroxide whitening agent. Unlike other whitening agents that work by removing stains on the surface of the tooth, hydrogen peroxide can get inside the tooth so it whitens intrinsically as well as extrinsically. Sachar also recommends this toothpaste, saying,

Google adds iPhone-like ‘Calling Cards’ to its Phone app

Google’s Phone app is adding “Calling Cards” that let you customize the appearance of contact screens for incoming calls. They’re similar to the Contact Poster feature that iPhone users have had since 2023, allowing Google Phone app users to replace the teeny contact photos that appear when someone is calling you with full-screen images and stylized names. The update is part of Android’s Material 3 Expressive design language overhaul, which Google used to test a revamped Phone app interface in

HP Coupon Codes and Deals: Up to 60% Off | September 2025

If you don't know where to start—and use—your HP coupon code, there’s a wide variety of options available at HP.com in terms of budget and use case, but my eye goes first to the high-end HP Omen gaming monitors, like the fantastic HP Omen Transcend 32. This 4K 240Hz monitor is a favorite among PC gamers, even among the huge amounts of OLED options out there. It can hit a peak brightness of over 1,000 nits in HDR, bringing scenes in games to life in vivid detail. Or if you’re on the other side o
