This Arch-based Linux distro has a clean, privacy-focused experience for tinkerers

Jack Wallen / Elyse Betters Picaro / ZDNET Arch Linux has a reputation for being too complicated, unstable, and not for everyone. For those reasons, several distributions have emerged that attempt to bring Arch to the masses. Many of them (such as Manjaro and EndeavorOS) succeed quite well. However, not all of those forks of Arch are created equal. Take, for example, Liya Linux. This distribution was created and maintained by an individual to be an Arch-based Linux distribution that's simple t

7 ways Linux can save you money

Elyse Betters Picaro / ZDNET Over the past few decades, I've watched many people spend huge amounts of money keeping their computers running or up to speed with modern technology. I've seen friends take their computers to support specialists to rid them of malware (spending more money than they'd prefer) and, lately, been privy to countless users faced with buying new machines to replace those running Windows 10.

Distillation makes AI models smaller and cheaper

The Chinese AI company DeepSeek released a chatbot earlier this year called R1, which drew a huge amount of attention. Most of it focused on the fact that a relatively small and unknown company said it had built a chatbot that rivaled the performance of those from the world’s most famous AI companies, but using a fraction of the computer power and cost. As a result, the stocks of many Western tech companies plummeted; Nvidia, which sells the chips that run leading AI models, lost more stock valu

Birthright citizenship ruling now part of Apple’s appeal argument against Epic Games

In its ongoing appeal against Epic Games over App Store rules, Apple has decided to cite a recent U.S. Supreme Court decision on President Trump’s birthright citizenship directive. Here are the details. In a new filing submitted to the Ninth Circuit Court of Appeals this week (via Reuters), Apple argues that a June Supreme Court decision in Trump v. CASA directly supports its effort to overturn two injunctions issued in its long-running antitrust case against Epic Games. Apple’s argument is th

My 10 favorite Linux distributions of all time, ranked

Jack Wallen / Elyse Betters Picaro / ZDNET Linux is on the rise. I believe the popularity of the open-source operating system will continue to increase and possibly even hit the 10% mark by the end of 2025. Some say that's a pipe dream, but I believe. Because of the popularity of Linux, I thought I would create a list of my all-time top 10 distributions that I've used over the years. Some of these distros are no longer with us, while some of them are still thriving. Are you ready to take a

Swift-erlang-actor-system

I'm excited to share a new actor system we've been building for Swift's distributed actors: swift-erlang-actor-system. This actor system enables Swift programs to join a distributed Erlang cluster. Here's an example of a simple chat program using the actor system: Demo Video Erlang (and other languages that run on its VM) can connect multiple runtime systems together with distributed Erlang. Each runtime is referred to as a "node". Erlang also supports "C nodes", which allow a program other

Neptune Dances in Sync With a Rare Distant Object, Astronomers Find

For lovers of newly identified space objects, July has indeed been an exciting month. Last week, astronomers described Ammonite, a potential dwarf planet beyond Pluto. Yesterday, astronomers announced the existence of BetelBuddy, a small companion star orbiting Betelgeuse. And now we have another exciting discovery to share. In a Planetary Science Journal paper published earlier this month, astronomers with the Large inclination Distant Objects (LiDO) survey reported the discovery of 2020 VN40,

Intel announces end of Clear Linux OS project, archives GitHub repos

Clear Linux is a Linux distribution developed and maintained by Intel, featuring aggressive optimizations for Intel hardware. Binaries are compiled using tuning flags designed explicitly for Intel CPUs. It was a minimalist, modular OS that utilized software bundles for faster app installation and automatic performance tuning for optimal speed and power effic

3 Best Hall Effect Keyboards for Gamers and Serious Typists (2025)

Polling rate is likely one of the most prominently displayed details on any Hall effect keyboard, purely because the large numbers emphasize one of the most important aspects of these keyboards: Speed. Whether a keyboard has a 1,000- or 10,000-Hz polling rate, this number represents how many messages are sent from the keyboard to the PC every second. For example, a keyboard with 1,000-Hz polling will send 1000 messages every second. Most office equipment operates at 125 Hz. In high-performance g

Petabit-class transmission over > 1000 km using standard 19-core optical fiber

An international research team led by the Photonic Network Laboratory at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), and including Sumitomo Electric Industries, Ltd. (Sumitomo Electric, President: INOUE Osamu) have set a new world record in optical fiber communications, achieving data transmission at 1.02 petabits per second over a distance of 1,808 kilometers (roughly equivalent to the distance from Sapporo to Fukuoka, from Misso

6 reasons why I've stuck with Ubuntu-based Linux distros for the last 20 years

Jack Wallen / Elyse Betters Picaro / ZDNET It was October 2004, and I'd been using Red Hat Linux (way before it became Fedora) for years. I was fairly certain that would be my distribution until the world ended. I'd become comfortable with Red Hat. Sure, it had its quirks and was sometimes a bit more difficult than it needed to be (remember, it was over 20 years ago), but it was stable and I'd grown to know it well. But then a new distribution arrived on the scene... Ubuntu. Oddly enough, the

Embedding user-defined indexes in Apache Parquet

Embedding User-Defined Indexes in Apache Parquet Files Posted on: Mon 14 July 2025 by Qi Zhu, Jigao Luo, and Andrew Lamb It’s a common misconception that Apache Parquet files are limited to basic Min/Max/Null Count statistics and Bloom filters, and that adding more advanced indexes requires changing the specification or creating a new file format. In fact, footer metadata and offset-based addressing already provide everything needed to embed user-defined index structures within Parquet files w

This Linux distro combines the best parts of Windows and MacOS - and it's gorgeous

Jack Wallen/ZDNET There are so many Linux distributions on the market, and they range from the command line only all the way to functioning works of art. The majority of distros fall somewhere in the middle, of course, and that's perfectly fine because most users prefer a blend of aesthetics and functionality. That's why the likes of Linux Mint, ZorinOS, elementaryOS, and Ubuntu are so popular. But every once in a while, a team releases an update to its distribution that reminds you that Linux

HyAB k-means for color quantization

HyAB k-means for color quantization Color quantization in CIELAB space, visualized. The input is converted to CIELAB space and a special “HyAB” distance formula is used when clustering. This in theory should result in better image quality. I’ve been obsessing over color quantization algorithms lately, and when I learned that an image conversion app called Composite did its so-called pixel mapping step in CIELAB space, I instantly thought of the “HyAB” color distance formula I’d seen in the FLI

Collatz's Ant and Σ(n)

Collatz's Ant and Σ(n) Relevant preceding posts here and here. Consider the corresponding ant’s landscape development for $n = 500$: with the last frame being: Let’s also consider a score function $\Sigma(n)$ which returns the number of 1’s (or marked states) left by the ant on the corresponding landscape (regarding the last frame). With the prior example, we would have $\Sigma(500) = 54$. We might also want to normalize this by the corresponding stopping time $\tau_{n}$ characteristic of th

Teen drivers spend 21% of the time looking at their phones, reveals alarming study [Video]

A alarming new study has found that som teen drivers in the US spend as much as 21% of their time at the wheel looking at their phones, creating a substantial risk of distracted driving crashes. While much of this was brief glances, more than 5% of driving time comprised looking at their phone for 2+ seconds a time, long enough to qualify as dangerous … CNET reports that the teens did this despite understanding the risks they are taking. The study includes survey responses from 1,126 teen dri

Scary Survey Results: Teen Drivers Are Often Looking at Their Phones

A new study reveals that teen drivers in the US are spending more than one-fifth of their driving time distracted by their phones, with many glances lasting long enough to significantly raise the risk of a crash. Published in the journal Traffic Injury Prevention and released on Thursday, the research found that, on average, teens reported looking at their phones during 21.1% of every driving trip. More than a quarter of those distractions lasted two seconds or longer, which is an amount of time

4 Linux distros that can't be upgraded on autopilot - and why they're still worth trying

Jack Wallen / Elyse Betters Picaro / ZDNET If you use a Linux distribution based on Debian or Ubuntu, the upgrade path is almost always painless. I've had maybe one Ubuntu upgrade in over a decade that had problems, and even that was a fairly straightforward fix. But not all Linux distributions are created equal, and some are more challenging than others. Some distributions even make the upgrade process more difficult, and a few give users fair warning about why it's important to stay informed

7 things every Linux beginner should know before downloading their first distro

Jack Wallen / Elyse Betters Picaro / ZDNET I can still remember the moment I switched from Windows to Linux. Back then, I didn't have anyone there to tell me what to expect. It would have been nice to get even a bit of advice from someone with Linux experience in the know to say, "Hey, you'll want to know about this before you start down that path." It would have made things easier. Instead, I took just dove right in, hoping I could figure it all out as I went. The good news: Linux today is n

Apple fires back at court’s ‘punitive’ App Store order in Epic Games case

After a couple of weeks of radio silence in the Epic Games, Inc. v. Apple Inc. case, Apple’s lawyers are now back with a vengeance in the Ninth Circuit. And this time, they’re not just pushing back on the original outcome, but also asking the Ninth Circuit to assign the case to a different judge if it is sent back to the district court. As reported by Law360, in a new appeals brief filed Monday, Apple challenges the district court order that bars it from charging any commission on in-app purcha

Judge rules Anthropic's AI training on copyrighted materials is fair use

Anthropic has received a mixed result in a class action lawsuit brought by a group of authors who claimed the company used their copyrighted creations without permission. On the positive side for the artificial intelligence company, senior district judge William Alsup of the US District Court for the Northern District of California determined that Anthropic's training of its AI tools on copyrighted works was protected as fair use.

Painting with Math: A Gentle Study of Raymarching (2023)

Most of my experience writing GLSL so far focused on enhancing pre-existing Three.js/React Three Fiber scenes that contain diverse geometries and materials with effects that wouldn't be achievable without shaders, such as my work with dispersion and particle effects. However, during my studies of shaders, I always found my way to Shadertoy, which contains a multitude of impressive 3D scenes featuring landscapes, clouds, fractals, and so much more, entirely implemented in GLSL.
