Ubuntu Linux lagging? Try my 10 go-to tricks to speed it up

Yuichiro Chino/Getty Unless you're using a computer from the '90s or early 2000s, typically speaking, Ubuntu runs very well on most machines. I've found it to be fairly predictable in that respect. However, nothing is perfect, and you might run into an instance where the open-source operating system doesn't perform up to your standards. So, what do you do? Do you hop to a different distribution? You certainly could, as there are plenty of Linux distributions that work perfectly on older hardwa

How I survived a week with this $130 smartwatch instead of my Garmin and Galaxy Ultra

Kospet Magic P10 smartwatch ZDNET's key takeaways The Kospet Magic P10 and R10 are on sale on Amazon for $130 each. The associated app is robust, the watch battery lasts for more than a week, and the rugged design can handle all environments. The magnet on the charging cable is a bit weak and sleep mode doesn't turn the display off. View now at Amazon A few months ago, I tested a pair of Kospet Tank Ultra smartwatches and found them to be pretty compelling for their $150 price point. Since th

Words about Arrays and Tables

July 30, 2025 2000 words about arrays and tables THEY'RE JUST FUNCTIONS I'm way too discombobulated from getting next month's release of Logic for Programmers ready, so I'm pulling a idea from the slush pile. Basically I wanted to come up with a mental model of arrays as a concept that explained APL-style multidimensional arrays and tables but also why there weren't multitables. So, arrays. In all languages they are basically the same: they map a sequence of numbers (I'll use 1..N ) to homog

Launch HN: Lucidic (YC W25) – Debug, test, and evaluate AI agents in production

Hi HN, we’re Abhinav, Andy, and Jeremy, and we’re building Lucidic AI ( https://dashboard.lucidic.ai ), an AI agent interpretability tool to help observe/debug AI agents. Here is a demo: https://youtu.be/Zvoh1QUMhXQ. Getting started is easy with just one line of code. You just call lai.init() in your agent code and log into the dashboard. You can see traces of each run, cumulative trends across sessions, built-in or custom evals, and grouped failure modes. Call lai.create_step() with any metad

Big Tech Killed the Golden Age of Programming

Big Tech Killed the Golden Age of Programming The reason it's so hard to get a programming job right now is because Big Tech caused it. It's not an accident. It's not the result of regular cycles of employment or the economy. For years, companies like Google, Facebook/Meta, and Amazon hired too many developers. They knew they were hiring too many developers, but they did it anyway because of corporate greed. They wanted to control the talent pool. They wanted to make as much money as possible,

A Rare Flu Complication Is Killing More U.S. Children

A rare, life-threatening complication caused by the flu seems to be surging among kids. Research out today finds that dozens of children developed influenza-associated acute necrotizing encephalopathy (ANE) over the past two years, a third of whom died as a result. Researchers at Stanford Medicine led the study, published Thursday in JAMA. Collecting reports from other doctors and hospitals across the country, they identified 41 cases of ANE since 2023, along with 11 deaths. The researchers arg

Physicists Catch ‘Ghost Particles’ Bouncing Off Matter in Record-Breaking Experiment

Neutrinos are everywhere. About 100 trillion neutrinos pass through our bodies every second, but they’re so weakly interacting we never notice them. It’s this spooky feature of neutrinos that earned them the nickname “ghost particles.” Antineutrinos, their antimatter counterpart, are also everywhere. Both are notoriously difficult to detect, but physicists are getting better at circumventing their ghostly tendencies, as a recent record-setting measurement demonstrates. When a low-energy neutrin

Matt Shakman Thinks What Was Cut From ‘Fantastic Four’ Was for the ‘Greater Good’

It’s been just shy of a week since Marvel’s latest installment in its ever-expanding cinematic universe, The Fantastic Four: First Steps, released in theaters. While much of the hubbub about the film is generally favorable, verging on “we’re so back,” some online fans lamented over the movie seemingly leaving a lot of content from its trailer on the cutting room floor for their liking. Now, director Matt Shakman has come forward to discuss the rigorous editing process behind the Marvel film. In

Watch a Reconstructed 250-Year-Old Robotic Painting Bring a Fiery Mount Vesuvius Back to Life

Sir William Hamilton was the British ambassador to the court of Naples and Sicily from 1765 to 1800, as well as a passionate volcanologist. During his time in Italy he must have seen Mount Vesuvius erupt a number of times—certainly enough to leave a lasting impression. So much so that in 1775 he designed a rotating device that, with mechanical movement and light, could bring to life the fiery magma depicted in Pietro Fabris’ 1771 watercolor, “Night view of a current of lava.” While experts aren

Even The Guy Who Makes ChatGPT Says You Probably Shouldn't Use Chatbots as Therapists

Maybe don't tell your deepest, darkest secrets to an AI chatbot like ChatGPT. You don't have to take my word for it. Take it from the guy behind the most popular generative AI model on the market. Sam Altman, the CEO of ChatGPT maker OpenAI, raised the issue this week in an interview with host Theo Von on the This Past Weekend podcast. He suggested that your conversations with AI should have similar protections as those you have with your doctor or lawyer. At one point, Von said one reason he w

Not (just) seeing red: Virtual Boy emulator adds full color support

Here at Ars, we're big fans of classic console emulators that go beyond providing perfect re-creations to those that actually improve on original hardware with new features we could only dream of as kids. So we were excited when we recently stumbled on a Reddit post that shows a full Super Game Boy-esque color palette added to the usual shades of red and black found in Virtual Boy Wario Land. After experiencing colorized Virtual Boy emulation for ourselves (and grabbing the sample screenshots y

Pokémon TCG Pocket will change card art after plagiarism accusations

is a reporter focusing on film, TV, and pop culture. Before The Verge, he wrote about comic books, labor, race, and more at io9 and Gizmodo for almost five years. While you can now start collecting Pokémon TCG Pocket’s Johto-themed Wisdom of Sea and Sky expansion, two of the set’s rarest cards are being changed in response to concerns about art theft. Soon after dataminers began posting images of Wisdom of Sea and Sky’s cards on Tuesday, Chinese artist lanjiujiu took to their X account with qu

How 2 UC Berkeley dropouts raised $28 million for their AI marketing automation startup

AI-powered marketing automation startup Conversion, founded five years ago by two UC Berkeley dropouts, has raised a $28 million Series A led by Abstract, with participation from True Ventures and HOF Capital. The company’s founding story sounds like it could have been an episode of the HBO show “Silicon Valley.” The story begins all the way back when co-founder and CEO Neil Tewari, now 24, was in high school. He got busted one day watching a TechCrunch Disrupt livestream during class, was sen

Skechers is making kids’ shoes with a hidden AirTag compartment

Skechers introduced a line of kids’ sneakers that contain a hidden compartment where parents can slip in an Apple AirTag. Inside the heel of the shoe, a small insert can be lifted to reveal the compartment. Then, parents can track the location of their child — or, at least their child’s shoes. These shoes don’t come with an AirTag, and they don’t appear to be an actual collaboration with Apple, but rather, a third-party product that Skechers has developed on its own. The shoes were announced i

Minnesota activates National Guard as cyberattack on Saint Paul disrupts public services

Minnesota Gov. Tim Walz has activated the state’s National Guard following a cyberattack on the state’s capital, Saint Paul. City officials have not yet disclosed the nature of the cyberattack, but the July 25 breach continues to disrupt city operations and some public services. Saint Paul is one of the largest cities in the U.S. with more than 300,000 residents, and is the latest in a list of major cities targeted by hackers and ransomware gangs in recent years. In a statement on Tuesday, Wal

NBA quietly trials smart basketballs with embedded sensors and AI tracking

In brief: Kinexon and other companies have spent years refining connected-ball technology to enhance sports analytics, improve training, and collect more data than ever. As professional leagues begin adopting the new tech, questions remain about potential minute changes to basketball physics. Unbeknownst to most players, about half of the NBA games played in Las Vegas earlier this month used balls equipped with smart tracking technology. The league is considering full adoption, but one company

Google says it never received a UK demand for encryption backdoor, unlike Apple

A hot potato: Google says that unlike rival Apple, it has not received a demand from the UK government to build a backdoor in its encrypted services. The tech giant had refused to answer a US Senator's question on the matter, but it has since confirmed it is not subject to a similar order as Apple. In a letter to the Director of National Intelligence, Tulsi Gabbard, Senator Ron Wyden, who serves on the Senate Intelligence Committee, wrote about the UK's "reported secret surveillance demands of

Another Pixel 6a catches fire, despite Google's battery restrictions

Facepalm: Google released the Pixel 6a in 2022 as a mid-range variant of the Pixel 6 smartphone line. The device was initially praised for its so-called "flagship-level" performance and features, though it's now clear that the phone is far from perfect. A new Pixel 6a caught fire, even after Google released a crippling software update intended to limit the device's lithium-ion battery charge level. A Reddit user recently shared his harrowing experience, explaining that the phone essentially beg

Lawsuit Claims Meta Pirated Vast Numbers of Dirty Movies to "Train Its AI"

Mark Zuckerberg's Meta has been accused of pirating — we are not kidding — a whole adult bookstore's worth of dirty movies to train its artificial intelligence models. First flagged by the blog TorrentFreak, a copyright company called Strike 3 Holdings and an adult film studio called Counterlife Media have filed suit against Meta, alleging that the tech giant torrented nearly 2,400 copyrighted skin flicks. All in the name of AI research, of course. According to the suit, which was filed in Cal

The most powerful gaming handheld chipset will soon ship in this ‘budget’ handheld

AYANEO TL;DR AYANEO has revealed specs for the first device from its new sub-brand, the KONKR Pocket FIT. It packs with the most modern and powerful chipset for handhelds and a 8,000mAh battery. Pricing and launch dates have not been revealed, but it might be the best intro to high-performance emulation on the market. AYANEO made waves in the retro gaming handheld community when it announced a cheaper sub-brand called KONKR earlier this week, but it wasn’t immediately clear what pricing segm

YouTube is thinking about letting you avoid video comments entirely on mobile

Joe Maring / Android Authority TL;DR YouTube is testing a new mobile UI that hides several elements below the video player, including the channel name and comments section. Tapping a new dropdown arrow next to the video’s title reveals the hidden information, such as the creator’s channel details and subscriber count. This change declutters the screen to show more related videos, but adds an extra tap for users who want to read comments or visit the creator’s channel. To stay ahead of the co

M5 MacBook Pro could pose a big dilemma for upgrade decisions

If you’re interested in a new MacBook Pro, the current M4 model is an excellent option. But the M5 MacBook Pro will launch in the coming year too, and decisions about whether to upgrade could be a lot more complicated than usual. M5 vs M6 MacBook Pro: Two very different options For anyone expecting to upgrade their MacBook Pro in the coming year or so, Apple may have two very different options for you. The M5 MacBook Pro, which will launch either later this year or in early 2026, isn’t expect

Google will sign EU's AI Code of Practice

Google says it will sign the European Union’s new AI Code of Practice, which provides a framework for compliance with the EU’s AI Act. The act itself was passed in 2024, but its many provisions will take months to years to come into effect. The non-binding Code of Practice is a voluntary measure intended to help ensure that companies generally meet the obligations laid out by the Act in the meantime. In a blog post announcing Google’s participation, the tech giant shared some skepticism about t

The flaws, discovered by Binarly, mirror tho

Stanford's holographic AI glasses are coming for your clunky VR headset

Over the past couple of years, with the introduction of the Apple Vision Pro and the Meta Quest 3, I've become a believer in the potential of mixed reality. First, and this was a big concern for me, it's possible to use VR headsets without barfing. Second, some of the applications are truly amazing, especially the entertainment. While the ability to watch a movie on a giant screen is awesome, the fully immersive 3D experiences on the Vision Pro are really quite compelling. In this article, I'm
