ThinkPad designer David Hill spills secrets, designs that never made it

Interview Launched in 1992, the boxy black ThinkPad with its little red nub remains the quintessential business productivity notebook. Unlike commercial offerings from competitors such as Dell and HP, Lenovo's laptop has a following of people who collect old models and celebrate each new innovation. If you bought a ThinkPad between 1995 and 2017, it was probably designed under the oversight of David W. Hill, who served as lead designer under both IBM and Lenovo for those 22 years. We caught up

Hiding secret codes in light protects against fake videos

Fact-checkers may have a new tool in the fight against misinformation. A team of Cornell researchers has developed a way to “watermark” light in videos, which they can use to detect if video is fake or has been manipulated. The idea is to hide information in nearly-invisible fluctuations of lighting at important events and locations, such as interviews and press conferences or even entire buildings, like the United Nations Headquarters. These fluctuations are designed to go unnoticed by humans

Caches: LRU vs. Random

Once upon a time, my computer architecture professor mentioned that using a random eviction policy for caches really isn't so bad. That random eviction isn't bad can be surprising — if your cache fills up and you have to get rid of something, choosing the least recently used (LRU) is an obvious choice, since you're more likely to use something if you've used it recently. If you have a tight loop, LRU is going to be perfect as long as the loop fits in cache, but it's going to cause a miss every t

6 Weeks of Claude Code

6 Weeks of Claude Code Jul 30, 2025 - Orta Therox It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled myself from writing every line of code, I still consider myself fully responsible for everything I ship to Puzzmo, but the ability

We may not like what we become if A.I. solves loneliness

These days, everyone seems to have an opinion about A.I. companions. Last year, I found myself joining the debate, publishing a paper—co-written with two fellow psychology professors and a philosopher—called “In Praise of Empathic A.I.” Our argument was that, in certain ways, the latest crop of A.I.s might make for better company than many real people do, and that, rather than recoiling in horror, we ought to consider what A.I. companions could offer to those who are lonely. This, perhaps unsur

Great Tits Sometimes Break Up, Bird Researchers Find

We’re talking about the birds. Great tits are small, yellowish songbirds common to the woodlands of Europe. Tit pairs are known to be monogamous during breeding season, splitting up after fully raising their offspring. But new research suggests that this “tit divorce” may be the product of complex social relationships formed during and after the breeding season. Published July 30 in Proceedings of the Royal Society B, the paper reports that not all tit pairs separate in late summer when breedi

Flawed Tests on Earth May Explain Why NASA’s Rovers Get Stuck on Mars

In the spring of 2019, the six-wheeled Spirit rover was driving backwards to drag an inoperable front right wheel when it got stuck on the sandy Martian surface. Despite spending months trying to excavate its robot, NASA could not free Spirit. Now, engineers from the University of Wisconsin–Madison may have figured out a way to better prepare NASA’s robots for extraterrestrial environments. In a paper published in the Journal of Field Robotics, the team of engineers used computer simulations to

Bronze Age Humans Got High on Psychoactive Betel Nuts

Long before Ethiopian monks in the 9th century discovered that coffee tree fruit helped them stay awake during evening prayer (according to legend, anyway), communities in Southeast Asia have been chewing betel nuts—the seeds of the areca palm and a stimulant that heightens people’s alertness, energy, euphoria, and relaxation—since antiquity. But new research indicates that betel nut chewing has been practiced for even longer. By studying ancient dental plaque from Bronze Age individuals in Tha

Five children see HIV viral loads vanish after taking antiretroviral drugs

For years, Philip Goulder has been obsessed with a particularly captivating idea: In the hunt for an HIV cure, could children hold the answers? Starting in the mid-2010s, the University of Oxford pediatrician and immunologist began working with scientists in the South African province of KwaZulu-Natal, with the aim of tracking several hundred children who had acquired HIV from their mothers, either during pregnancy, childbirth, or breastfeeding. After putting the children on antiretroviral dru

Anthropic cuts off OpenAI’s access to its Claude models

In Brief Anthropic has revoked OpenAI’s access to its Claude family of AI models, according to a report in Wired. Sources told Wired that OpenAI was connecting Claude to internal tools that allowed the company to compare Claude’s performance to its own models in categories like coding, writing, and safety. TechCrunch has reached out to Anthropic and OpenAI for comment. In a statement to Wired, an Anthropic spokesperson said, “OpenAI’s own technical staff were also using our coding tools ahead

7 ways Google could make a Pixel Flip the best flip phone foldable out there

C. Scott Brown / Android Authority Google is preparing to launch the Pixel 10 Pro Fold this month, marking the company’s third foray into the foldable phone space. What if you want a pocket-friendly Pixel foldable, though? Unfortunately, Google hasn’t launched a Pixel Flip, and we don’t expect one any time soon. That means Samsung and Motorola are the only globally available options if you want a foldable flip phone. That’s a real shame, because I can think of several ways that Google could ma

Gone but not forgotten: Survey reveals Android users miss these features the most

Dhruv Bhutani / Android Authority Our smartphones have undergone profound commodification. But in the process of forging them into objects we use and rely on for nearly every waking hour, phone companies have focused a lot on optimizing utility, which, in turn, has resulted in many key features being dropped from our beloved devices. These days, leading brands especially insist on slimming down phones more, even going against what users may truly want. So, to get a sense of which features our

This is my favorite Android launcher, and it’s not the one you think

Nathan Drescher / Android Authority We’re probably a lot alike when it comes to launchers. I’ve been bouncing between them for years, trying each one out, getting excited about updates and then being let down when they offered nothing new. I’ve paid for pro launchers and tried going with the locked down stock launcher on a Google Pixel, but nothing really stuck, until Smart Launcher 6. My Redmagic 10 Pro is my current daily driver. However, its stock launcher is the definition of “just good en

I’ve used Pixel and Galaxy phones for a decade, and Google wins in one aspect every time

Robert Triggs / Android Authority I’ve been using smartphones since 2011, and they’ve all been Samsung and Google devices (aside from a few other brands due to my job). Both companies have come a long way over the years, and while the S24 Ultra is my phone of choice for now, that may soon change for one reason. Pixels and Galaxy phones each have their strengths and weaknesses, but one thing I’ve always found Google is best at is customer support, while Samsung has more reliable devices. As I t

Anthropic says OpenAI engineers using Claude Code ahead of GPT-5 launch

Anthropic says it has revoked OpenAI's access to the Claude API after ChatGPT's engineers were found using Claude's coding tools. Claude Code is better than any other coding tool in the AI coding industry, also known as "Vibe coding." With Claude, you can create web apps from scratch, and it's also pretty efficient with infra-related work. Not just vibe coders who don't know how to code use Claude, but also professional engineers. In fact, Claude Code is also used in Claude's development at

OpenAI prepares new open weight models along with GPT-5

OpenAI isn't just working on GPT-5. It looks like OpenAI is also preparing to release new open-source weights, living up to its name, "OpenAI." As spotted on X, two new open-source weights, "gpt-oss-20b" and "gpt-oss-120b," have been spotted on HuggingFace, which is an AI platform to host models. The models are on HuggingFace ahead of the public release. Typically, companies like OpenAI need to share the model weights with partner companies. This is done in preparation for the release. OpenA

The First Widespread Cure for HIV Could Be in Children

For years, Philip Goulder has been obsessed with a particularly captivating idea: In the hunt for an HIV cure, could children hold the answers?

While Microsoft is not opening it fully yet, the company shared details about plans for the next six months,

Tesla Found Partly Liable in 2019 Autopilot Death

A Miami jury found Tesla partially liable Friday in a 2019 crash that killed one person and injured another—all while the driver of the Model S used the automaker’s Autopilot driver assistance feature. The jury found Tesla liable for $200 million in punitive damages, plus an additional $43 million in compensatory damages. (Because of state laws, the company will likely end up paying less.) A jury found the automaker one-third responsible for the crash; it found the driver of the Tesla, who sett

‘Sleeping Giant’ Fault Under Canada Shows Major Earthquake Potential

After 12 millennia of relative inactivity, a geologic fault that stretches across the territory of Yukon, Canada, and Alaska now appears capable of producing a major earthquake, according to a new study. The findings point to an underrecognized source of seismic hazard in northwestern Canada. Scientists previously believed that the Tintina fault, which extends roughly 620 miles (1,000 kilometers) from northeast British Columbia through the Yukon and Alaska, remained quiet for the last 40 millio

Look to the Sky: Bright Fireballs Appear During the Perseids Meteor Shower

Skygazers rejoice, the summer isn't finished with delivering meteor showers to feast your eyes on. Last week saw dueling meteor showers taking over the sky, but the most popular meteor shower of the year won't hit its peak until next week. The Perseids meteor shower is about to give you a real light show, provided you're far enough away from light pollution to see it. Perseids are known for their bright fireballs and plentiful meteors. The show started on July 17, and will run through Aug. 23.

Everyone Should Have Exactly 3 Pairs of Headphones, and These Are My Picks. Here's Why

When people ask you what your "big three" are, they might be asking about your sun, moon and rising astrological signs. But when I ask my friends the same question, I'm not trying to determine their horoscope. Instead, I'm curious what their headphones and earbuds collection looks like. After more than a decade working as a technology journalist, I'm in the fortunate position of having what most people would consider to be too much tech in my house. I make a real effort to keep it to a minimum

Chess grandmaster Carlsen wins at Esports World Cup

Chess grandmaster Carlsen wins at Esports World Cup The inclusion of chess in this year's schedule was somewhat controversial, but the tournament's organisers argued it counted as an esport as it is played by millions of people of all ages. The Esports World Cup (EWC) being held in Riyadh, Saudi Arabia is one of the biggest multi-discipline tournaments in competitive professional gaming. Number one grandmaster, Magnus Carlsen, has won the inaugural online chess competition at the Esports Worl

The tradeoff between human and AI context

AI coding is a skill. You have to decide how much context to put in your brain vs the AI. You can waste your time thinking about the wrong problem because you failed to delegate. Or you can give yourself a headache when the AI coder doesn’t get it. I think about it in terms of spectrum of human to AI context. At the highest levels, we, humans, own all the context. We operate here when our specific value-add matters. We also work here in the many cases AI coders aren’t that smart yet. At the low
