This is a guest post from my friend Łukasz Izdebski Ph.D. Intro It’s been a while since my last guest post on Adam’s blog, but I’m back with something short and practical—think of it as an epilogue to this earlier post on Bézier curves in animation. The last post focused on the theory and mathematics behind Bézier curves. What it lacked was a practical perspective—an opportunity to see the implementation in action. I wanted to share with you a simple library that I have created. Its purpose is
8.4 / 10 SCORE Alienware Area-51 Desktop Pros Strong 4K performance Filtered air intakes Reasonably priced configuration options No more proprietary madness Cons Absolutely huge Leaves performance on the table at 1080p Still expensive The Alienware Area-51 (AAT2250) is quite something. Its monstrous size and weight may make it a lot to deal with, but it also moves away from some of the chaotic proprietary componentry that made earlier Alienware products harder to recommend. Once you get
New findings this week showed that a misconfigured platform used by the Department of Homeland Security left sensitive national security information—including data related to the surveillance of Americans—exposed and accessible to thousands of people. Meanwhile, 15 New York officials were arrested by Immigration and Customs Enforcement and the New York Police Department this week in or around 26 Federal Plaza—where ICE detains people in what courts have ruled are unsanitary conditions.

ABC suspended Jimmy Kimmel Live! on September 17 after the late-night host commented on the killing of conservative activist Charlie Kirk. His monologue suggested Trump supporters were trying to reframe the shooter’s political ties, which drew backlash from the FCC and major ABC affiliates. ABC replaced the program with reruns, sparking accusations of censorship and igniting a boycott campaign against Disney, its parent company. Overwhelming public reaction The suspension triggered strong resp
You may have heard lately that tattoos can potentially raise your risk of skin cancer. Recent research might complicate that narrative, however, suggesting that tattoos aren’t as harmful to our skin as assumed. Scientists at the University of Utah led the study, published last month in the Journal of the National Cancer Institute. Contrary to their expectations, they found that people who had multiple tattoos actually had a lower associated risk of melanoma. That said, the findings don’t provid

Robert Triggs / Android Authority When switching to any new technology, there’s always a subset of techies curious about how things work—myself included. One of the biggest changes in the Pixel 10 series is the Tensor G5 processor’s new PowerVR GPU, built by Imagination Technologies. Browsing through the graphics chip’s specs, a few things stand out. The core can support ray-tracing, but Google seems to have left this unimplemented. The peak GPU clock is reported at 1.1GHz; however, corners of
Once upon a time, noise-canceling headphones primarily existed for one purpose: air travel. Bose and Sennheiser were among the first on the scene commercially, blocking unwanted sounds for pilots long before wireless headphones were even a thing. Today, active noise cancellation (ANC) is not just commonplace, it's practically expected for any consumer headphone. During the development of its four sets of AirPods with ANC, Apple has harnessed the power of its noise-blocking system to create a na
28 Years Later, the third release in Danny Boyle's iconic zombie franchise, premiered in theaters earlier this year. Just in time for spooky season, the hit horror movie is coming to streaming -- and it's happening this week. Over two decades ago, Boyle partnered with Alex Garland to bring 28 Days Later to life. It was followed by the sequel, 28 Weeks Later, in 2007. Instead of your typical undead fare, the franchise features a new type of threat: Running zombies infected with a biological weap
Mass is still the enemy here, and EVs typically have lots of it. Factor in bigger brakes and wheels, and the result is an increase in unsprung mass. That puts the springs and dampers under more pressure, which results in an increased amount of energy that needs to be managed, and unwanted oscillations when a car hits a pothole, for example. A car also wants to pivot around what’s known as the center of yaw. If you can locate as much mass as possible close to that point, then the car will rotate
China is calling a TikTok deal a win. What's in it for them? 10 hours ago Share Save Suranjana Tewari Asia Business Correspondent and Osmond Chia Business reporter Share Save Getty Images A much-awaited deal over TikTok may be close, with US President Donald Trump and his Chinese counterpart Xi Jinping set to discuss terms on Friday. Top officials from both sides struck a "framework" agreement this week, which reports suggest could see TikTok's US operations sold to a group of American firms.
In brief A new Stanford study explores how fruit fly populations maintain genetic diversity amid changing environments, which is crucial for survival against future challenges. The research provides direct evidence to support the theory of “dominance reversal” in genetics. Findings indicate that genetic variants can act as dominant or recessive based on environmental conditions – which gives the flies long-term pesticide resistance. Populations live in rapidly changing environments – droughts
On Wednesday, Meta CEO Mark Zuckerberg unveiled a slew of new augmented reality glasses, including what he claimed to be the "first AI glasses with high resolution," a new $799 version of its Meta Ray-Ban smart glasses that features a tiny screen that's viewable to the wearer. But it didn't take long for the company's MetaConnect 2025 keynote to descend into chaos. The social media giant's demos repeatedly failed, leading to awkward stares, deafening silences, and muted laughter. The poor show
Season two of Gen V, the college-aged spin-off of The Boys that some fans argue outshines the original, is back in action, kicking off on Prime Video with a three-episode drop. And its new season wastes no time confronting the tragic passing of cast member Chance Perdomo. In the wake of the gnarly superhero show’s premiere, its showrunner shared how the team chose to honor Perdomo’s legacy throughout the show. Speaking with Deadline, co-showrunner Michele Fazekas unearthed how the writer’s room

NASA released a significant update from the Perseverance Mars rover on Sept. 10, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars. That's possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry riv
Understanding Deflate I’m trying to understand how Deflate works so decided to compress a simple string TOBEORNOTTOBEORTOBEORNOT using GZIP then decode the resulting file by hand. Compressing the data Pretty simple here, text in bytes out: $ echo -n 'TOBEORNOTTOBEORTOBEORNOT' | gzip -n | xxd -ps -u 1F8B08000000000000030BF17772F50FF2F30F09013342605C00F14E3D2D 18000000 Reading the GZIP data Even though I’m really interested in the compressed data I have to decode the GZIP “wrapper” in order
Indoor air quality is important. It increases comfort. Potentially, it might improve cognition as well as reducing infection risk in a space. And it would be cool to have Swiss quality air in my house! One can increase air quality by improving ventilation. One way to do this is by turning on a fan near your window. The CDC recommends facing them towards the outside to exhaust air out the house. (I will be writing more about this later). When it comes to fans, the stronger the better. But there
Anthropic, the artificial intelligence company behind the chatbot Claude, is trying to carve out a spot as the Good Guy in the AI space. Fresh off being the only major AI firm to throw its support behind an AI safety bill in California, the company grabbed a headline from Semafor thanks to its apparent refusal to allow its model to be used for surveillance tasks, which is pissing off the Trump administration. According to the report, law enforcement agencies have felt stifled by Anthropic’s usa

This is a guest post from Jiebin Sun, Zhiguo Zhou, Wangyang Guo and Tianyou Li, performance optimization engineers at Intel Shanghai. Intel's latest processor generations are pushing the number of cores in a server to unprecedented levels - from 128 P-cores per socket in Granite Rapids to 288 E-cores per socket in Sierra Forest, with future roadmaps targeting 200+ cores per socket. These numbers multiply on multi-socket systems, such servers may consist of 400 and more cores. The paradigm of "m
Anthropic is in the midst of a splashy media tour in Washington, but its refusal to allow its models to be used for some law enforcement purposes has deepened hostility to the company inside the Trump administration, two senior officials told Semafor. Anthropic recently declined requests by contractors working with federal law enforcement agencies because the company refuses to make an exception allowing its AI tools to be used for some tasks, including surveillance of US citizens, said the off
