An LLM does not need to understand MCP

Model Context Protocol (MCP) has become the standard for tool calling when building agents, but contrary to popular belief, your LLM does not need to understand MCP. You might have heard about the term "context engineering"; where you, as the person interacting with an LLM, are responsible for providing the right context to help it answer your questions. To gather this context, you can use tool calling to give the LLM access to a set of tools it can use to fetch information or take actions. MCP

Outdated Software, Nationwide Chaos: United Grounds Flights After Meltdown

United Airlines passengers across the country found themselves stranded, confused, and angry on Wednesday as a massive technology failure triggered a nationwide grounding of flights. The culprit: Unimatic, a decades-old internal system so vital to United’s operations that when it failed, the airline had no choice but to bring the entire operation to a standstill. From major hubs in Chicago, Newark, Denver, Houston, to San Francisco, the outage rippled through the airline’s scheduling, flight

Infinite Pixels

I was on one of my rounds of social media trawling, just seeing what was floating through the aether, when I came across a toot by Andy P that said: Fun #css trick: width: calc(infinity * 1px); height: calc(infinity * 1px); …and I immediately thought, This is a perfect outer-limits probe! By which I mean, if I hand a browser values that are effectively infinite by way of the infinity keyword, it will necessarily end up clamping to something finite, thus revealing how far it’s able or willi

Best Tested Walking Pads (2025): Urevo, WalkingPad, Sperax

Sitting at your desk all day is literally a pain. It’s bad for your mental and physical health and slowly turns you into a hunched-over keyboard gargoyle. You could take walking breaks away from your screen, but even then you’re still spending a lot of the day on your butt. Enter: the walking pad. These tiny treadmills fit under standing desks and allow you to rack up steps while you work. It might sound far-fetched, but yes, you can exercise and be productive on your computer at the same time.

Android 16 lets the Linux Terminal use your phone’s entire storage

Mishaal Rahman / Android Authority TL;DR The Terminal app on Pixel phones enables users to run Linux apps via a Debian virtual machine. The Android 16 Beta 4, and subsequently the stable Android 16 release, removed the previous 16GB storage cap for the Linux VM.

Bose’s stylish SoundLink Home speaker is cheaper for the first time in months

Audio quality is always going to be a speaker’s most important feature, but it doesn’t hurt if it looks nice too. In our tests, Bose’s SoundLink Home is a solid sounding, aesthetically pleasing portable Bluetooth speaker that you can currently pick up for $199.99 ($20 off) from Amazon, Best Buy, and Bose. The SoundLink Home’s aluminum band and fabric covering distinguish it from the plastic shells used for other speakers, and are likely to be the first things you notice. However, former Verge r

5 Linux distros I recommend to help businesses cut costs and boost security

PM Images/Getty Images Businesses around the world may not realize this, but they absolutely depend on Linux and open-source. Without those two pieces of technology, we wouldn't have nearly the services and sites we now enjoy. But Linux isn't just a good option for servers and technology stacks. Linux is also viable as a desktop operating system. Why? It's not only one of the most reliable platforms available, it's also very secure… and cost-effective.

5 command line backup tools every Linux user should use for desktops and servers

Javier Zayas Photography/Getty Images I use Linux for both desktop and server. My preference for a server OS is one without a GUI, which means I have to turn to a lot of command-line tools. In some cases, I prefer to use the same command-line tools for both desktop and server, because it simplifies everything. After all, I don't want to have to learn two different tools for the same job. On top of that, the command-line tools I've included in this list are very powerful and flexible enough to m

Call to vet YouTube ads like regular TV to stop scams

Call to vet YouTube ads like regular TV to stop scams Google, which owns YouTube, has said it strives to support an "advertising ecosystem that's trustworthy and transparent for users". Last week, Ofcom's annual report found that YouTube had overtaken ITV to become the UK's second most-watched media service behind the BBC.

Josh Brolin on ‘Weapons,’ ‘Dune 3’ Teases, and Why He Hates Modern Marketing

Josh Brolin had had the kind of career most actors can only dream about. He’s done it all, working with all the biggest directors, writers, and producers in every genre, from western to sci-fi and back around again, sometimes both at the same time. And, when you talk to him, you feel that experience. That gravitas. That expertise. It’s incredibly cool, very impressive, and just a tiny bit intimidating. io9 spoke to Brolin recently about his latest film, Weapons, which opens August 8. Written an

Illinois is the first state to ban AI therapists

Illinois Governor JB Pritzker has signed a bill into law banning AI therapy in the state. This makes Illinois the first state to regulate the use of AI in mental health services. The law highlights that only licensed professionals are allowed to offer counseling services in the state and forbids AI chatbots or tools from acting as a stand-alone therapist. HB 1806, titled the Wellness and Oversight for Psychological Resources Act, also specifies that licensed therapists cannot use AI to make “th

Google is building a Linux terminal app for native Android development - here's why that's huge

Jack Wallen/ZDNET ZDNET's key takeaways Google is developing another Linux terminal app. The app runs a full Debian environment. Developers will be able to build Android apps on device.

Perplexity gives Apple new reason not to acquire the AI company

Perplexity has long been accused of deliberately bypassing anti-scraping measures to retrieve web content. While the company has historically dismissed these accusations as disingenuous or misunderstandings, a new report shows that not only is the practice still happening, but it may actually be getting worse. Perplexity’s main counter-argument: semantics The issue with Perplexity’s web crawling practices first came to light in June 2024, when Wired and other media outlets accused the company

This Linux distro makes Slackware easier than ever

Jack Wallen / Elyse Betters Picaro / ZDNET ZDNET's key takeaways Slackel is a user-friendly take on the otherwise challenging Slackware. There are four different desktop variations to choose from. Slackel is a great distribution for learning Linux. Slackware has been around since 1993 and has served as the foundation for many Linux distributions, such as the early iterations of SUSE. What sets Slackware apart from other Linux distributions is that it tries to be more UNIX-like than not. Sla

Yes, you need a firewall on Linux - here's why and which to use

JuSun/Getty ZDNET's key takeaways Linux is highly secure, but you should still have a firewall. You should know if your ISP's hardware (gateway) uses a firewall. One of the easiest Linux firewalls is UFW and its GUI sidekick, GUFW. I've been using Linux for nearly 30 years. Over those years, I've experienced only one security issue (a rootkit on a server I inherited). The reason for that is Linux's heightened security. Out of the box, it includes a tight permissions system and security mech

5 of my favorite Linux system-monitoring tools - and why I use them

Here you'll learn about htop, glances, Mission Center, and more apps. Linux users are notorious for wanting to know as much information as they can about their systems and how they run. There are even apps and widgets (such as Conky) that can be installed and configured to display such information right on t
