Plug-in hybrid electric vehicles (PHEVs) are perfect if you want some electric driving without the stress of range limits. Most have enough pure EV range to cover your everyday drives, and when the battery dips, the hybrid mode kicks in as a handy backup.

Gas prices are skyrocketing across the country. According to AAA, the national average for a gallon of regular fuel is $3.88 at the time of this writing. That is about a 33 percent increase from just one month ago. Last night I paid $5.09 per gallon for 94 octane. I could have gone out for a nice steak dinner for the price of filling my tank. So, in times like these, it is natural for people to try to get the most out of a gallon of gas.

Nearly three decades after helping establish the large luxury SUV segment alongside the Cadillac Escalade, the 2026 Lincoln Navigator is showing off its new exterior and a tech-focused interior that centers on wellness and relaxation. Lincoln sometimes refers to the 2026 Navigator as a “spa” or “sanctuary” on wheels, a mantra the automaker adopted after the large SUV's redesign in 2025.

Nothing seemed amiss as NASA's experimental X-59 supersonic jet touched down after its second test in the air, smoothly coasting onto the runway. 

But the sleek, needle-nosed airplane had completed only nine minutes in the air on Friday, March 20, before a cockpit warning light forced an early landing. That warning was separate from a caution light that occurred during an earlier takeoff attempt just before 10 a.m. P.T., said Cathy Bahm, project manager at NASA's Armstrong Flight Research Center.

The brief flight left from Edwards Air Force Base in California at 10:54 a.m. P.T. marked only the second time the aircraft had flown. While the team originally planned for about an hour, leaders stressed that even short flights provide new data for moving the project forward. You can watch the landing in the video below. 

Bob Pearce, who heads NASA's aeronautics research, said the team made the right call to cut the flight short on Friday. The agency expects to find and fix issues at this stage of an X‑plane, an aircraft the U.S. builds to test new flight technologies and ideas.

"Sometimes it's easy to forget that building this kind of experimental aircraft means creating something that never existed before," Pearce said during a news conference. "As far as X-planes go, it's not unusual."

The X-59 is part of a long-term effort to change how fast commercial airplanes fly over land. Traditional supersonic aircraft create a loud boom when they break the sound barrier, which is why the U.S. government bans routine supersonic passenger flights over populated areas. NASA and its contractor, Lockheed Martin, built the X-59 to fly faster than sound while producing only a "thump," with the goal of providing regulators and the industry with the evidence needed to reconsider the restrictions.

At the kind of supersonic speeds NASA wants to target for the X-59 — around 925 mph — a nonstop flight from New York to L.A. could take less than three hours. Today's commercial airlines typically cruise at about 550 mph on that route, so passengers tend to spend about 5 to 6 hours crossing the country.

A sonic boom occurs when a plane flies faster than the speed of sound, compressing pressure waves into a single shock wave that hits the ground like a sudden explosion of air. NASA designed the X‑59 so its shape spreads those pressure changes out along the aircraft, turning that single sharp shock into a series of smaller pulses.

Residents below didn't hear the X-59's thump during either of the first two test flights — and they weren't supposed to. The plane never flew fast enough either time to make it. Both flights intentionally stayed at subsonic speeds. NASA is using these early tests to shake out systems and watch how the plane handles. 

During Friday's test, the aircraft was supposed to fly for roughly an hour, reaching a cruising speed of 230 mph at 12,000 feet before accelerating to 260 mph at 20,000 feet. The plane never exceeded 230 mph, officials said.

"I certainly hoped to have more to talk about than nine minutes of flight," said Less, who flew the X-59 for the first time on this mission. "Although I had not intended to have to land quite as urgently for my first landing, the plane performed beautifully."

He described the aircraft as handling just like its simulators. Over hundreds of hours of test runs in the simulator, Less and other test pilots had practiced with the unconventional vision system that combines images from cameras into a high-definition display. But this was his first time flying without the traditional front window. 

The long nose shape that helps soften the sonic boom doesn't leave room for a standard cockpit windscreen. But in some cases, the system offers better visibility than the naked eye, he said. If a pilot is facing into the sun, for example, image processing can reduce glare and improve contrast. 

"It really felt comfortable," he said. "Even though I wasn't seeing out the front, I could see out the sides and match that up." 

More than 100 test flights are planned. NASA intends to gradually push toward higher, faster flights before testing those muffled booms over towns.

Every time I install Ubuntu, whether it's a fresh setup or an upgrade—I follow a checklist of tweaks I immediately apply. It's a set of changes I always make to ensure the system feels comfortable, familiar, and efficient for me.

It's hard to believe that the whole real-time ray-tracing thing started all the way back in 2018, with the release of the NVIDIA GeForce 20-series of GPUs. Suddenly, the lighting method used in high-end pre-rendered Hollywood movies could be used in live video games. Well, at least that was the promise.

It's important to make your workspace comfortable. You'll likely be spending 8 hours a day there—and staring at a drab, lifeless setup isn't conducive to productive work, especially if the space isn't even designed to make working easier.

Everyone loves a good television show, but what makes one a classic is its ability to stand the test of time. That means immense rewatchability, cultural impact, and consistent, high-quality storytelling. Shows that do are often nostalgic and resonate across generations, creating memorable characters and embedding themselves in the public consciousness.

Android’s notification system is one of its strongest features. However, as much as I try to keep things tidy, there are a lot of settings to check. Thankfully, a recent “Notification Organizer” feature does all the hard work for me.

I recently repurposed an old laptop I had lying around into my first makeshift NAS by adding a hard drive and USB-C hub to it. It initially started mostly as a curiosity, mostly to see what it’s like to own a NAS. What I thought would be a quick weekend project quickly turned into an ongoing learning experience, but I’m glad I did it.

Have you ever had a Home Assistant automation grind to a halt because something went wrong during one of the actions? Sometimes this is desirable, but in some circumstances, it might be better if the rest of the automation continues to run even if one of the actions fails. Thanks to a recent Home Assistant update, it's now possible to get your automations to continue running even when an error occurs.

Apple TV has all kinds of new shows and new seasons scheduled to land over the next five or so months. But that's kind of the problem—you're paying for the service, so what's there to watch right now? I've got you.

AirTags used to be the best trackers in Apple's Find My network, but that is no longer the case. The ecosystem has expanded, and there are now many more devices to choose from. Here is how the AirTag lost its crown as the top Bluetooth tracker—and what you should buy instead.

When we think of PC upgrades, we usually think of a graphics card, RAM, maybe a CPU, maybe an SSD ... Coincidentally, all but one of those components are outrageously overpriced right now, and CPUs were never that cheap to begin with.

Storage fills up faster than it should, especially when you're juggling multiple machines. Between older PCs, test systems, and everyday use, I've learned that low disk space rarely tells the full story. Windows will give you a vague breakdown, but it doesn't actually show you what's going on. I've had drives that looked full for no obvious reason, and digging through folders manually never gave me a clear answer.

If your Linux system crashes and locks you out, you risk losing everything—files, data, time. If you have a bootable Linux USB recovery disk, tough, you'll be ready to restore, repair, and rescue your system before it’s too late.
