CNET's experts have tested a dozen new air purifiers with comprehensive new lab tests to evaluate them for particle filtering, noise and energy efficiency. Here are our five new winners.
While OpenAI continues to insist that there are currently no ads — or tests for advertising — live in ChatGPT, the company’s chief research officer also acknowledged that the company “fell short” with recent promotional messages.
There are plenty of well-known models among the 8-bit machines of the 1980s, and most readers could rattle them off without a thought. They were merely the stars among a plethora of others, and even for a seasoned follower of the retrocomputing world, there are fresh models from foreign markets that continue to surprise and delight. [Dave Collins] is treating us to an in-depth look at the VTech VZ-200, a budget machine that did particularly well in Asian markets. On the way, we learn a lot about a very cleverly designed machine.
The meat of the design centres not around the Z80 microprocessor or the 6847 video chip, but the three 74LS chips handling both address decoding and timing for video RAM access. That they managed this with only three devices is the exceptionally clever part. While there are some compromises similar to other minimalist machines in what memory ranges can be addressed, they are not sufficient to derail the experience.
Perhaps the most ingenuity comes in using not just the logic functions of the chips, but their timings. The designers of this circuit really knew the devices and used them to their full potential. Here in 2025, this is something novice designers using FPGAs have to learn; back then, it was learned the hard way on the breadboard.
We answer questions about replacing long HDMI runs with wireless extender options, diagnosing YouTube TV lag on a TCL set, and whether plasma TVs still make sense today.
Streaming services such as Spotify and Apple Music give you access to hundreds of millions of songs, but they're quite restrictive in how you can use them. They may not include some of the music you want to listen to, and you may not be able to play those streaming services through some of your speakers. Music Assistant allows you to play music from a wide range of sources on almost any speaker in your home.
Driving today is all about balancing focusing on the road while trying to handle all the other things that happen when you are navigating busy streets. Waze understands that the best way to make roads safer and get the most efficiency is by letting drivers chat with the app.
2025 is the year I bought both a Nintendo Switch 2 and a Samsung Galaxy XR headset, but my favorite tech purchase isn’t either of those things. That would, surprisingly, be a night light. But this isn’t just any night light.
Colin Jost's Pete Hegseth returned to Saturday Night Live this week to kick off the Melissa McCarthy-hosted episode, featuring Dane Cook jokes, 6-7, and the ongoing conflict with Venezuela.
The Defense Secretary sauntered into the White House press room like a WWE superstar, crushing cans and berating journalists with insults like a particularly annoying middle school bully as he answered questions about what he dubbed "Operation Kill Everybody."
"As you probably read in some gay newspaper, we're now at war with Venezuela," the government leader told the press pool.
Hegseth was joined by "reporter" Matt Gaetz (Sarah Squirm) and "high-energy Alpha" President Donald Trump (James Austin Johnson), with the latter nodding off in the corner while dreaming about NYC Mayor-Elect Zohran Mamdani.
"Homebrew, the package manager for macOS and Linux, just got a handy new feature in the latest v5.0.4 update," reports How-To Geek.
Brewfile install scripts "are now more like a one-stop shop for installing software, as Flatpaks are now supported alongside Brew packages, Mac App Store Apps, and other packages."
For those times when you need to install many software packages at once, like when setting up a new PC or virtual machine, you can create a Brewfile with a list of packages and run it with the 'brew bundle' command. However, the Brewfile isn't limited to just Homebrew packages. You can also use it to install Mac App Store apps, graphical apps through Casks, Visual Studio Code extensions, and Go language packages. Starting with this week's Homebrew v5.0.4 release, Flatpaks are now supported in Brewfiles as well...
This turns Homebrew into a fantastic setup tool for macOS, Linux, and Windows Subsystem for Linux (WSL) environments. You can have one script with all your preferred software, and use 'if' statements with platform variables and existing file checks for added portability.
Chinese robotics company Unitree has revealed its much larger humanoid robot, the H2, can fight. We dig into all the hidden details in the company's latest demo videos.
At CES 2026, Lenovo going all-in on AI (like every other company), but it’s hiding all the fun goodies in the back, and I’m excited about what might be coming.
If you work with PDFs a lot, you often have to choose between expensive proprietary software or free alternatives that have lackluster features or questionable privacy and security. But what if I told you that you can have the best of both worlds? It's called BentoPDF.
