21 Best Festival Accessories and Gear (2025): The Essentials and the Fun Stuff

On Harm Reduction Photograph: The Bunk Police Regardless of your personal habits, drug use can be prevalent at festivals. It's important to know the location of medical tents, to pay attention to your surroundings, and to look out for your fellow festival attendees the way you'd want them to look out for you. I highly recommend getting trained in administering naloxone (Narcan). It prevents opioid overdose, and it's easy to obtain training and the medicine itself for cheap. I took mine throug

This free GPT-5 feature is flying under the radar - but it's a game changer for me

Sabrina Ortiz/ZDNET ZDNET's key takeaways ChatGPT's Advanced Voice Mode is now available for free users. With the feature, users can access a conversational voice assistant. Advanced voice, now known as ChatGPT voice, replaces Standard Voice Mode. While OpenAI's new large language models (LLMs) in ChatGPT, such as GPT-5, which just launched today, typically steal the spotlight, some of the best gems are found in the less talked-about features, like Advanced Voice Mode. Also: GPT-5 is final

Why I ditched Google Chrome for Firefox Focus within 10 minutes of using the mobile browser

Jack Wallen / Elyse Betters Picaro / ZDNET ZDNET's key takeaways Firefox Focus is a security and privacy-focused mobile browser. This browser offers a minimal UI and maximum privacy features. Firefox Focus is available for both Android and iOS. I've run the gamut of web browsers on Android, and every time I think I've found "the one," I discover a reason not to use it. That reason might be a cluttered UI, a lack of options, or not enough security. Recently, however, I came across a browser

Window Activation

You click a link in your chat app, your browser with a hundred tabs comes to the front and opens that page. How hard can it be? Well, you probably know by now that Wayland, unlike X, doesn’t let one application force its idiot wishes on everyone else. In order for an application to bring its window to the front, it needs to make use of the XDG Activation protocol. A KWrite window that failed to activate and instead is weeping bitterly for attention in the task bar In essence, an application ca

I used Perplexity to make a restaurant reservation - now I'm wondering if Google is holding us back

Tang Ming Tung/Getty Images ZDNET's takeaways Perplexity's new feature lets you make a restaurant reservation straight through OpenTable. The feature uses OpenTable's system, so you don't have to trust the AI to do it for you. Instead of navigating between apps or tabs to find a restaurant and then book a table, Perplexity handles everything. Finding the perfect restaurant and making a reservation just got a whole lot easier thanks to a new feature in Perplexity. The chatbot (which ZDNET's

Trump opens door for crypto in retirement accounts

Trump opens door for crypto in retirement accounts But critics say it could increase risks for savers. The move is intended to eventually give everyday workers new access to investments formerly reserved for wealthy individuals and institutions, while opening up previously untouched pools of funding for firms in those fields. On Thursday, he ordered regulators to look for ways to change rules that might discourage employers from including such offerings in workplace retirement accounts, known

Instacart tops estimates, issues upbeat outlook

The Instacart logo is seen on a smartphone and on a PC screen. Simo, who helped take the grocery delivery company public in 2023 and guided it through a massive growth period during the Covid-19 pandemic, will step down from her position later this month as she joins OpenAI as its new head of applications. "We delivered another strong quarter, reinforcing the essential role we play in helping families save time, money, and effort putting food on the table," wrote outgoing CEO Fidji Simo in a s

Specifically, xAI has made the Grok Imagine tool for turning images into short videos available for free for everyone. Grok Imagine is one of the few image-to-video generative AI tools publicly available for free. Access to the tool is available inside the Grok app on iOS and Android. Grok Imagine first has you generate or upload an image, then it presents a button to convert it into a video

Zero-day flaws in authentication, identity, authorization in HashiCorp Vault

Introduction: when the trust model can’t be trusted Secrets vaults are the backbone of digital infrastructure. They store the credentials, tokens, and certificates that govern access to systems, services, APIs, and data. They’re not just a part of the trust model, they are the trust model. In other words, if your vault is compromised, your infrastructure is already lost. Driven by the understanding that vaults are high-value targets for attackers, our research team at Cyata set out to conduct

ChatGPT can now talk nerdy to you - plus more personalities and other upgrades beyond GPT-5

How to sell if your user is not the buyer

And then quickly, in one of my private communities, I had this question pop up: But how you would talk to your ideal customer if they are not the ones who try the product?

AI Ethics is being narrowed on purpose, like privacy was

A few days ago, OpenAI released an open-source language model for the first time in a very long time. It had been promised for a while, but the deadline kept being pushed for “safety” concerns. In fact, they’ve put quite a bit of time and effort into discussing safety, because, ostensibly, safety and ethics is at the top of people’s minds. So, the public is worried about AI ethics, and OpenAI is putting efforts into making sure the AI is ethical. Sounds like a match. Not just a match, but a

Let's stop pretending that managers and executives care about productivity

Let's stop pretending that managers and executives care about productivity I’ve just been on a bit of a summer break. Did a bit of travel locally. Visited Hvalfjörður. Walked a lot. I know from experience that if I don’t take a summer break, the winter becomes more of a slog and my thoughts become groggier. Often, as soon as you rest, your mind starts to “helpfully” come up with ideas to help fill your time. One of the invasive thoughts that kept prodding my brain during my break was about mo

Monte Carlo Crash Course: Quasi-Monte Carlo

Monte Carlo Crash Course Quasi-Monte Carlo We’ve learned how to define and apply Monte Carlo integration—fundamentally, it’s the only tool we need. In the remaining chapters, we’ll explore ways to reduce variance and successfully sample difficult distributions. Variance & Correlation In chapter two, we determined that the variance of a Monte Carlo estimator is inversely proportional to its sample count. Empirically, we confirmed that our integrators’ expected error scaled with $$\frac{1}{\sq

OpenAI Is About to Make Employees Millionaires

It’s a figure so large it almost loses meaning: $500 billion. That is the staggering valuation OpenAI, the company behind the revolutionary ChatGPT, could soon command. The company is in discussions with investors for a deal that would allow its current and former employees to sell their privately held shares, a source familiar with the matter told Gizmodo. This type of deal, known in financial jargon as a secondary sale or a tender offer, would more than double OpenAI’s recent $260 billion val

Baltimore Assessments Accidentally Subsidize Blight–and How We Can Fix It

One of the biggest challenges facing Baltimore is blight. For decades, the city has grappled with population loss, leaving behind thousands of vacant homes and empty lots that scar neighborhoods. These empty spaces not only serve as a constant reminder of visible decline, but also drain city coffers and undermine community safety. Both the city and the state have launched ambitious initiatives to tackle this very problem. But what if the government’s own policies were quietly making the problem

Infinite Pixels

I was on one of my rounds of social media trawling, just seeing what was floating through the aether, when I came across a toot by Andy P that said: Fun #css trick: width: calc(infinity * 1px); height: calc(infinity * 1px); …and I immediately thought, This is a perfect outer-limits probe! By which I mean, if I hand a browser values that are effectively infinite by way of the infinity keyword, it will necessarily end up clamping to something finite, thus revealing how far it’s able or willi

CNET's key takeaways No robot vacuum has truly solved the challenge of multi-level cleaning without requiring you to physically move it between floors. This robo-vac can do

Photographer spends years on street corner capturing same commuters daily (2017)

For 9 years, from 8:30 am and 9:30 am, Danish photographer Peter Funch stood at the southern corner of 42nd Street and Vanderbilt Avenue. In the rush of commuters, what he found was a glimpse of universal habits and the long trek to work. From 2007 to 2016 Funch carried out his project 42nd and Vanderbilt in which he captures the same person twice, mid-commute, leaving the viewer to wonder if they were photographed days, months, or even years apart. This simple surveillance exercise lets viewer
