There is no memory safety without thread safety

There is no memory safety without thread safety Memory safety is all the rage these days. But what does the term even mean? That turns out to be harder to nail down than you may think. Typically, people use this term to refer to languages that make sure that there are no use-after-free or out-of-bounds memory accesses in the program. This is then often seen as distinct from other notions of safety such as thread safety, which refers to programs that do not have certain kinds of concurrency bugs

Google's AI-Powered Virtual Try-On for Online Shopping Is Now Live

Google's Try On, an AI-powered feature in Search that allows you to try on clothes virtually, is now live, the company said Thursday. Try On, previously limited to Labs users, is opening itself up to the broader Google user base. When people search for clothes to buy via Google Search, some items will have a "Try it on" button. It'll then use a photo of you (or one you've uploaded of someone else) and render the clothing over your or their body, taking into account your/their size and shape and

Google has new ideas on how to save money while shopping online

Ryan Haines / Android Authority TL;DR Google has begun rolling out its AI-powered tool that lets you try on new clothes. Additionally, it is bringing an advanced price tracker in Shopping results that alerts you every time the price of a saved product drops below a specified value. In the coming fall, it will also allow users to use AI Mode to get inspiration for outfits and interior design. In addition to rolling out AI Mode to all users in the US, Google showcased its AI-powered Try It On

XOR_singleheader: Header-only binary fuse and XOR filter library

Header-only Xor and Binary Fuse Filter library Bloom filters are used to quickly check whether an element is part of a set. Xor filters and binary fuse filters are faster and more concise alternative to Bloom filters. Furthermore, unlike Bloom filters, xor and binary fuse filters are naturally compressible using standard techniques (gzip, zstd, etc.). They are also smaller than cuckoo filters. They are used in production systems. This is a simple C header-only library. It implements both binar

Google’s new AI feature lets you virtually try on clothes

Google announced on Thursday that it’s launching a new AI feature that lets users virtually try on clothes. The tech giant is also rolling out updated price alerts and teased an upcoming feature that will let users explore shoppable outfits and room inspiration using generative imagery. The official launch of the virtual try-on feature comes two months after Google first began testing it. The feature works by allowing users to upload a photo of themselves to virtually try on a piece of clothing

This Nearly Perfect Gaming Keyboard Is Held Back by a Few Big Compromises

Finding the perfect keyboard can often feel like looking for a needle in a haystack. There's no shortage of mechanical keyboards offering a whole range of features and hardware options. While the "perfect keyboard" likely doesn't exist, there are certainly some good ones to be found. Finding a solid balance between hardware, features and price can be daunting. While Cherry's MX 8.2 TKL keyboard delivers fantastic hardware, there are compromises as well. I spent several weeks typing and gaming o

Dynabook Portégé Z40L-N Review: Replaceable Batteries, High Price

Back in, say, 2001, business travelers would hop on an international flight not just with their laptop, but with three or four spare batteries also tucked into their attaché case. The extra batteries could add roughly 6 pounds to your load, but it was a necessary evil—each of those batteries would probably only offer about three or four hours of run time, barely enough to update your Lotus 1-2-3 spreadsheet. Coming up with novel ways to keep track of which batteries were charged and which were s

What role should oil and gas companies play in climate tech?

Standing on top of a drilling rig in the backyard of Nabors’s headquarters, I couldn’t stop thinking about the role oil and gas companies are playing in the energy transition. This industry has resources and energy expertise—but also a vested interest in fossil fuels. Can it really be part of addressing climate change? The relationship between Quaise and Nabors is one that we see increasingly often in climate tech—a startup partnering up with an established company in a similar field. (Another

I'm never toting ice after testing this portable smart cooler - here's why

ZDNET's key takeaways The Anker Solix EverFrost 2 is available for $1,349 but currently on sale. This cooler works as a portable mini-fridge, with dual-zone cooling and the capacity to freeze or refrigerate. The Anker Solix EverFrost 2 is bulky and heavy, and it only comes with one battery so you have to purchase the second to reach the full 3.2 day capacity.

Another Galaxy S26 Ultra leak pours cold water on a battery upgrade

Joe Maring / Android Authority TL;DR Another leaker has claimed that the Galaxy S26 Ultra will have a 5,000mAh battery. This comes after a reliable outlet made the same claim earlier this month. That means Samsung’s Ultra phone will have the same battery capacity for the seventh time. We’ve seen many flagship Android phones with huge batteries this year, but the Galaxy S25 Ultra retains a 5,000mAh battery. We previously heard that Samsung won’t change things on the Galaxy S26 Ultra, and anot

Nvidia supplier SK Hynix posts record second-quarter profit and revenue on strong AI memory demand

Nvidia supplier SK Hynix second-quarter profit and revenue hit record highs, topping estimates

The SK Hynix Inc. logo is displayed on a glass door at the company's office in Seoul, South Korea, on Monday, Jan. 27, 2014. SK Hynix aims to select a U.S. site for its advanced chip packaging plant and break ground there around the first quarter of next year. South Korea's SK Hynix on Thursday posted record operating profit and revenue in the second quarter on sustained demand for its high bandwidth memory technology used in generative AI chipsets. Here are SK Hynix's second-quarter results c

Fusion Startup Says It's Figured Out How to Turn Mercury Into Gold

A fusion energy startup claims to have found a way to turn mercury into gold. As the Financial Times reports, San Francisco-based Marathon Fusion says that the same process that could one day represent a limitless source of clean energy could also be used for literal alchemy. As detailed in a yet-to-be-peer-reviewed paper, nuclear transmutation — effectively changing an element or isotope into a different one by ripping out protons from its nucleus — could be used to synthesize gold particles.

Someone Just Sold Their 2011 Bitcoin for a 17 Million Percent Profit

A mysterious Bitcoin account has cashed out a cache of cryptocurrency they originally bought for $54,000 — but which, after HODLing for 14 long years, is now worth an astronomical $9.5 billion, for a staggering profit of over 17 million percent. Bitcoin whales, meaning accounts that hold on to substantial sums of crypto for long periods at a time, have been making moves as of late, Tom's Hardware reports, reaping enormous returns as crypto markets reach all-time highs. Just last week, a differ

Trump Media Is Now a $2 Billion Bitcoin Bet

Trump Media isn’t just fighting Big Tech. It’s taking on Wall Street with a Bitcoin war chest big enough to rival corporate heavyweights. The company behind Truth Social and streaming platform Truth+ announced, on July 21, it had purchased $2 billion worth of Bitcoin and Bitcoin-related securities, converting two-thirds of its $3 billion in liquid assets into cryptocurrency. It’s one of the boldest corporate Bitcoin strategies ever seen, rivaling billionaire Michael Saylor’s MicroStrategy (now

Microsoft backtracks on $80 The Outer Worlds 2 pricing

There's hope that the gaming industry won't follow Nintendo's lead with $80 pricing. (Well, at least not yet.) On Wednesday, Microsoft backtracked on the price increase for The Outer Worlds 2. The game now costs $70, which itself was considered outrageous only a few years ago. Microsoft told Windows Central that those who already pre-ordered Obsidian's shooter at $80 can get refunds at the point of purchase. Unfortunately, you can't simply get a $10 price adjustment. You'll have to refund the f

Interactive Programming in C (2014)

December 23, 2014 nullprogram.com/blog/2014/12/23/ I’m a huge fan of interactive programming (see: JavaScript, Java, Lisp, Clojure). That is, modifying and extending a program while it’s running. For certain kinds of non-batch applications, it takes much of the tedium out of testing and tweaking during development. Until last week I didn’t know how to apply interactive programming to C. How does one go about redefining functions in a running C program? Last week in Handmade Hero (days 21-25),

Samsung Galaxy S26 Edge rumor teases the best of both worlds

Ryan Haines / Android Authority TL;DR The next Galaxy Edge phone is rumored to be even thinner than its predecessor. The rumor also suggests that the device may have a larger battery. To achieve this feat, Samsung may use “new battery material technology.” The Galaxy S25 Edge stands out from the rest of the Galaxy S25 line due to its slim and light design. However, to achieve this slender frame, Samsung had to make a number of sacrifices, which may have played a hand in its poor sales number

Avalanche Energy hits key milestone on the road to a desktop fusion reactor

For every technology, there comes a tipping point where it switches from theory to possibility. Robin Langtry believes that Avalanche Energy has reached that point. Avalanche recently operated its desktop fusion machine for hours on end while maintaining 300,000 volts, a figure the startup predicts will allow it to build a reactor capable of generating more energy than it consumes, the holy grail for any fusion company. Where other fusion companies need powerful magnets to generate energy, Ava

This Compact Gaming Keyboard Gets a Lot Right, but a Few Things Wrong Too

One of the best things about mechanical keyboards, at least for me, is that there are a ton of choices and options so you can find the one that perfectly fits your preferences. Whether you're a hardcore gamer who needs the biggest, best and fastest one around or you're a more causal gamer who needs something great at work and occasional play, there's something for everyone. Cherry has long been one of the best keyboard makers and continues to have a huge presence and influence on the industry.

This E-Sports-Inspired Gaming Mouse Left Me Wanting More

You'd be forgiven for thinking that every computer mouse is just like every other computer mouse. It clicks things on your screen and lets you move your cursor around. Believe it or not, there are quite a few ways companies can differentiate their mice from each other, especially when it comes to gaming. Gaming mice can range from just a few dollars to well over a hundred dollars, but you don't always get what you pay for. That's why I'm here. You might recognize Cherry as the company that's do

I Asked Pro Chefs: What Are the Most Worthless Kitchen Tools?

Our kitchens have become hotbeds of innovation, packed with high-powered air fryers, countertop smokers and other impressive tools designed to make cooking easier. But not every gadget deserves a spot on your counter -- some are better off in the trash with the food scraps. Rather than falling for every shiny new trend, it's wiser to invest in reliable, versatile gear that can actually make life easier. To help separate the helpful from the hype, we asked chefs and kitchen pros to weigh in on t

I found a video doorbell that records in 2K - and it comes with zero monthly fees

Wild Video Shows Robot Changing Its Own Battery

What do they even need us for anymore? Self Swap As we continue on our path towards a potential future filled with tireless humanoid robots staffing factory floors, companies are looking to solve a major pain point of the tech: a limited battery life. Chinese company UBTECH recently showed off its bipedal Walker S2 robot contorting its arms to hot swap one of its battery packs — a "world's first," seemingly — which means the 95-pound automaton could technically work 24 hours a day, an integra
