Don't animate height

Our app was mysteriously using 60% CPU and 25% GPU on my M2 MacBook. It turned out this was due to a tiny CSS animation! In this post, I show how to find expensive animations, why some are so expensive, and how to make many animations much cheaper. Along the way, we'll learn how the browser renders CSS animations and how to use Chrome's dev tools for performance profiling. The problem While building Granola, a note-taking app, I noticed it was using 60% CPU and 25% GPU on my M2 MacBook: Activ

Major European healthcare network discloses security breach

Telegram's crypto wallet goes live to its 87 million U.S. users

Telegram users in the U.S. can now send, receive, and manage cryptocurrency directly inside the app — no downloads, extensions, or separate logins required. TON Wallet is built into Telegram's interface and is beginning its U.S. rollout this week. It is a self-custodial crypto wallet in which a user controls their own private keys. The service, developed by The Open Platform, which is known as TOP, and built on the TON blockchain, allows users to send stablecoins and other digital tokens to th

I finally gave NotebookLM my full attention - and it really is a total game changer

Elyse Betters Picaro / ZDNET One of the best parts of my job is that I get to chat with industry folks who, like me, eat and breathe AI tools. After meeting with yet another (non-Google-affiliated) media person last week who told me how much they loved NotebookLM, I decided to give it a real try. Also: OpenAI wins gold at prestigious math competition - why that matters more than you think Although I've tried several NotebookLM features for the site before and have been impressed, finding a wa

I know genomes and I didn’t delete my data from 23andMe

As word spread last year that 23andMe was about to go bankrupt, many of their millions of customers wondered if they should delete their data. Social and conventional media were quick to offer advice, sometimes coming from experts in genetics and genomics–my field, I should note–on how to go onto the 23andMe website and delete all of your data. In March of this year, the California attorney general issued a warning that 23andMe was “in financial distress,” and he told Californians that they oug

Elon Musk’s X Says ‘Nope’ to French Authorities Trying to Access Its Algorithm

Onlookers have long suspected that Elon Musk’s X (formerly Twitter) has a right-wing bias embedded in its digital DNA, and, in January of this year, cybercrime authorities in France took it upon themselves to uncover whether this was true or not. The investigation has sought to determine whether the site is guilty of algorithmically manipulating the visibility of content on its website. NBC reports that, earlier this month, the probe was transferred to a “key unit of France’s national police.” N

My favourite German word

My favourite German word¶ 30th June 2025 A documentation colleague recently challenged me with a question: Nowadays, more and more people reach for an LLM tool to provide the information they want. If human beings don’t actually read it, what is the point of writing and structuring documentation for humans? Newer generations (she said) are becoming unskilled at finding information for themselves. They seem less able to digest what they find, to apply it to their problems. But it’s not just t

Mercedes-AMG gives us a ride in its next high-performance EV

Mercedes-Benz provided flights from Detroit to Stuttgart, Germany, and accommodation so Ars could be briefed on the AMG.EA prototype as well as the GT XX that we covered last month. Ars does not accept paid editorial content. First-generation high-performance electric vehicles, like the Tesla Model S Plaid, had a party trick that would wow first-timers: straight-line acceleration. Feeling your internal organs shift under the G forces of acceleration is cool the first few times but gets annoying

Polymarket Says It’s Coming Back to the U.S.

In 2022, the Commodities Futures Trading Commission accused Polymarket of having offered illegal trading services. Since then, as part of its settlement with the government, the site hasn’t operated inside the United States. However, the platform—which lets web users earn or burn cash via bets on anything and everything (from political races to farts)—now appears to be headed back to America, thanks in part to a recent business deal. In a press release published Monday, Polymarket announced tha

How to remove personal information to protect yourself from stalkers

With data brokers making big money by selling your personal details, it’s never been easier for bad actors to get access to your phone number, email address, physical address, and even sensitive data like your social security number. That doesn’t just leave you at risk from spammers and scammers, but some people unfortunately have to worry about their contact details being used for stalking and harassment … How to remove personal information Data brokers are companies whose business is buying

Microsoft wants to fix ‘slow or sluggish’ performance in Windows 11

is a senior editor and author of Notepad , who has been covering all things Microsoft, PC, and tech for over 20 years. Ever since Windows 11 first debuted in October 2021, there have been complaints about its performance on certain types of hardware. Whether it was gaming on new hybrid performance CPUs showing no improvement on Windows 11, or claims that Windows 11 simply feels lethargic compared to Windows 10, Microsoft has tried to fix the problems with updates to the OS. Now, it wants direct

Titan’s Methane Lakes Could Form Bubble-Like Structures Essential to Life, Scientists Say

On December 25, 2004, the Huygens probe separated from the Cassini spacecraft and landed on Titan’s sandy surface. The probe survived for 72 hours on Saturn’s largest moon, revealing a world that is chemically complex and more Earth-like than expected. For years, scientists have been intrigued by Titan as an alien world that might have the right conditions to host life, albeit in a very different form than on Earth. New research by NASA reveals that molecular precursors to life could form in Tit

The Ultimate Dolby Atmos Experience Might Be In Your Car

It’s fair to say that no five people crammed into a compact SUV have been more blissfully enthralled on a country drive than my wife’s family and I on one particular mid-summer Sunday. It wasn’t just the silky smooth performance of the Cadillac Optiq, or even its incredible 19-speaker AKG sound system, but an x-factor pushing our driving experience beyond the sum of their parts: Dolby Atmos Music. If you haven't heard it in a vehicle like this, you might think I'm joking. Everyone has probably

Rethinking CLI interfaces for AI

We need to augment our command line tools and design APIs so they can be better used by LLM Agents. The designs are inadequate for LLMs as they are now – especially if you're constrained by the tiny context windows available with local models. Agent APIs Like many developers, I’ve been dipping my toes into LLM agents. I’ve done my fair share of vibe coding, but also I’ve been playing around with using LLMs to automate reverse engineering tasks mostly using mrexodia’s IDA Pro MCP , including ex

ServiceNow’s acquisition of Moveworks is reportedly being reviewed over antitrust concerns

In Brief ServiceNow’s acquisition of enterprise AI startup Moveworks is reportedly drawing regulatory scrutiny. The acquisition is currently under review for antitrust by the U.S. Justice Department, according to Bloomberg, which cited sources familiar with the matter. The probe began in June, Bloomberg reported, and both companies have since received a “second request” calling for additional information that has to be provided before the deal can move forward.

WhatsApp streamlines in-app support process

If you’ve ever tried to get in-app support on WhatsApp, you know the process used to start with filling out a form, possibly attaching a few files, and waiting for a support rep to eventually get in touch. Now, that form is on its way out, and the screening process is, you guessed it, becoming AI-based. But that’s not necessarily a bad thing. Out with the form, in with AI Unless you’re Stephen Hackett, support knowledge bases are never fun to navigate, especially if you are in a hurry and alr
