New Tesla Cybertruck Model Trades Power For Longer Range And A Lower Price

New Tesla Cybertruck Model Trades Power For Longer Range And A Lower Price
Tesla’s polarizing Cybertruck has become more affordable with the introduction of a new entry-level trim. By dropping a few (arguably) big features, such as air suspension, power tonneau cover, ventilated front seats, plus moving from dual-motor all-wheel-drive to single motor rear-wheel-drive, the new Cybertruck Long Range comes in under

Intel Lunar Lake On Linux Can Roughly Match Windows 11 Xe2 Graphics – When Not Stuck At 400MHz

Earlier this month I looked at the AMD RDNA 3.5 graphics with Strix Point between Windows 11 and Ubuntu 25.04 Linux. The testing showed the AMD RDNA 3.5 graphics on the open-source Linux driver up to around 96% the performance of Radeon Software on Windows. The most frequent question that came up from that most recent round of benchmarking was wondering how the Intel Xe2 graphics on Core Ultra Series 2 “Lunar Lake” now compares between Windows 11 and Linux given that both drivers have been maturing the past several months. Here’s the story of the Xe2 graphics between Windows 11 and Ubuntu 25.04 while using a Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition laptop.

Blue Origin Sends All-Female Crew To Edge of Space in Historic Flight

Blue Origin’s New Shepard completed its 31st mission Monday morning, carrying the first all-female crew to space since Soviet cosmonaut Valentina Tereshkova’s 1963 solo flight. The NS-31 mission lifted off from West Texas at 9:30 a.m. EDT, with hundreds of thousands watching via livestream as the autonomous vehicle crossed the Karman line 62 miles above Earth.

The 10-minute suborbital journey carried six passengers: journalist and Bezos’ fiancee Lauren SÃnchez, former NASA scientist Aisha Bowe, bioastronautics researcher Amanda Nguyen, CBS journalist Gayle King, pop star Katy Perry, and film producer Kerianne Flynn. Bowe conducted three research experiments during the flight, while Nguyen became the first Vietnamese and Southeast Asian woman in space. The fully reusable New Shepard system features a pressurized capsule that separates from its booster before returning to Earth with three parachutes.

Overly Complicated Rube Goldberg Style Hand-Washing Machine

This is a video created by Joseph of Joseph’s Machines (previously) in collaboration with Dr. Squatch hand soaps of the automatic hand washing machine he constructed (not actually a Rube Goldberg machine because it’s powered). Does it look like a medieval torture device? Kind of. I especially liked the stuffed animal hand drying wheels at the end. Me? I dry my hands the old fashioned way. “Never washing them in the first place?” Come on, I’m not an animal, I just went to the bathroom. On my pants — the answer was ‘on my pants.’

OneXPlayer X1 Pro Gaming Tablet Gets Upgraded With Lots Of RAM And Storage
Remember the Intel Core Ultra 155H-powered One-Netbook OneXPlayer X1 gaming tablet from last year? After being updated to AMD Ryzen 7 8840U power a few months later, the device (rebadged as the X1 Pro) then gained a slightly more capable Ryzen AI 9 HX 370 processor and Radeon 890M GPU. If such a 3-in-1 gaming tablet wasn’t niche enough, One-Netbook

Coming Up: Matthew Lefthand’s 24-Hour Virtual World Record Attempt on April 19th

First, a Bit of Background…

Matthew Lefthand began cycling in July of 2022 after marathon training left him plagued with constant knee and foot troubles. Finding that pedaling did not inflame the pain, Matthew went on to complete several century rides in a 60-day ramp to complete his first road bike race ever: LOTOJA, a 208mi/334km point-to-point ride/race crossing three states and multiple mountain ranges. From that moment on, Matthew was hooked on cycling and was especially drawn to ultra distances.

After building fitness, gaining road skills, and essentially living on the bike (1200 hours/31,000 miles of riding each year) during the 2023 and 2024 seasons, Matthew did his first “real” ultracycling race, Hoodoo 500. After a bumpy start, nutritional disaster, and persevering through 20mph constant winds with gusts up to 40mph, he completed the 520mi/836km and 30,000ft/9,000m of elevation in 29h06m, besting the course record by 5 hours!

With this achievement, Matthew knew he had found his place and set out to specialize his training for ultracycling in 2025. With a winter of intense work under his belt, Matthew asked his good Zwift-friend, Chris “Hoppo” Hopkinson, which early 2025 race would be best to test the waters. Matthew added Bike Sebring to the calendar and put everything into preparation, including learning to ride on a liquid-only diet, attaching TT bars to his indoor bike to practice position, getting a professional TT bike fit, and learning everything he could about the stressors and tactics of a 24-hour race.

His result was very impressive, completing 576 miles in 24 hours at Sebring, surpassing any other American over that time and also any other cyclist during a non-drafting 24-hour race.

World Record Plans for 2025

Feeling on top of the world and gaining more supporters, Matthew set his 2025 schedule to pursue the WUCA World Cup and attempt a few World Records. Matthew told me he’s “not much of a racer.” However, he is attracted to the idea of pulling the most he can out of himself – studying the craft of ultracycling relentlessly to go as far as he can, as fast as he can.

Up Next: 24-Hour Virtual World Record Attempt

Matthew’s next challenge is a 24-hour Virtual World Record attempt on April 19th, hosted by ENVE and supported by Wahoo, Zwift, Rotor, and BrainStoke.

The attempt will begin at 8am ET on Tempus Fugit with a special robopacer named “No Limits Left(y)”. While it has a different name, the metrics of this bot are identical to Constance. Matthew aims to push his limits, break the record, and do it in a fair and equitable way for all who cycle virtually. In addition to the physical feat, Matthew is dedicating his ride to his mom, who is battling Stage 3 Breast Cancer. Incentives to give to the National Breast Care Foundation as well as directly to his mom’s treatment will be shared throughout the event.

Join Matthew!

Matthew invites the public to join him virtually (on Zwift) or physically. He will be riding beginning at 8am ET on April 19th.

ENVE HQ will be open to the public during the entirety of the event. If you are local to Ogden, Utah and want to join in person, Matthew’s team will have several indoor bikes set up, including a Zwift Ride and KICKR Core. You’re also welcome to bring your own bike and trainer. 

You can join via Zwift by searching for the “No Limits Left(y)” bot on Tempus Fugit. The event will also be streamed live on YouTube and feature interviews with Tyler Pearce (VC Adventures), Hoppo, Marko Baloh, Hayden “Farmwatts” Pucker, Magnus Kulset, Vidmar Mehl, and others. 

Details of the event can be found here. Be sure to follow Matthew for updated information: @matthew.lefthand on Instagram, Facebook, YouTube, TikTok, Strava, and Zwift.

(Matthew is additionally supported by Formula 369, Cycling Upgrades, MYB Supplements, Ventum, Peak State Fit, Infinity Seat, and Impermanence Counseling Services.)

F1 in Bahrain: I dare you to call that race boring

What a difference a week makes. This past weekend, Formula 1 went back to Bahrain, the site of this year’s preseason test, for round four of the 2025 season. Last week’s race in Japan sent many to sleep, but that was definitely not the case on Sunday. The overtaking was frenetic, the sparks didn’t set anything on fire, and the title fight just got that little bit more complicated. It was a heck of a race.

V10s? Not any time soon

Before the racing got underway, the sport got some clarity on future powertrain rules. An ambitious new ruleset goes into effect next year, with an all-new small-capacity turbocharged V6 engine working together with an electric motor that powers the rear wheels. Just under half the total power comes from the hybrid system, much more than the two hybrid systems on current F1 cars, and developing them is no easy task. Nor is it cheap.

F1 is also moving to supposedly carbon-neutral synthetic fuels next year, and that has prompted some to wonder—increasingly loudly—if instead of the expensive hybrids lasting for four years, maybe they could be replaced with a cheaper non-hybrid engine instead, like a naturally aspirated V10.

[$] In search of a stable BPF verifier

BPF is, famously, not part of the kernel’s promises of user-space stability. New
kernels can and do break existing BPF programs; the BPF developers try to
fix unintentional regressions as they happen, but the whole thing can be something of a bumpy
ride for users trying to deploy BPF programs across multiple kernel versions.
Shung-Hsi Yu and Daniel Xu had two different approaches to fixing the problem
that they presented at the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit.

[$] The state of the memory-management development process, 2025 edition

Andrew Morton, the lead maintainer for the kernel’s memory-management
subsystem, tends to be quiet during the Linux Storage, Filesystem,
Memory-Management, and BPF Summit, preferring to let the developers work
things out on their own. That changes, though, when he leads the
traditional development-process session in the memory-management track. At
the 2025 gathering, this discussion covered a number of ways in which the
process could be improved, but did not unearth any significant problems.

Facebook Sought To ‘Neutralize’ Competitive Threats, FTC Argues As Landmark Antitrust Trial Begins

An anonymous reader shares a report: An attorney for the Federal Trade Commission told a judge that Facebook, fearing the competitive threat of Instagram posted to their social media network, acquired both as a way to “neutralize” the rival. “They decided that competition was too hard,” the FTC’s attorney, Daniel Matheson, said in his opening statement in the government’s antitrust case against the Meta Platforms social media empire.

He argued that with Meta’s monopoly in social media, “consumers do not have reasonable alternatives they can turn to,” even as satisfaction has declined. At stake is the potential breakup of Facebook-parent Meta, as the government has zeroed in on the 2012 acquisition of Instagram and 2014 purchase of WhatsApp.

Live demos test effectiveness of Revolutionary War weapons

The colonial victory against the British in the American Revolutionary War was far from a predetermined outcome. In addition to good strategy and the timely appearance of key allies like the French, Continental soldiers relied on several key technological innovations in weaponry. But just how accurate is an 18th-century musket when it comes to hitting a target? Did the rifle really determine the outcome of the war? And just how much damage did cannon inflict? A team of military weapons experts and re-enactors set about testing some of those questions in a new NOVA documentary, Revolutionary War Weapons.

The documentary examines the firing range and accuracy of Brown Bess muskets and long rifles used by both the British and the Continental Army during the Battles of Lexington and Concord; the effectiveness of Native American tomahawks for close combat (no, they were usually not thrown as depicted in so many popular films, but there are modern throwing competitions today); and the effectiveness of cannons against the gabions and other defenses employed to protect the British fortress during the pivotal Siege of Yorktown. There is even a fascinating segment on the first military submarine, dubbed “the Turtle,” created by American inventor David Bushnell.

To capture all the high-speed ballistics action, director Stuart Powell relied upon a range of high-speed cameras called the Phantom Range. “It is like a supercomputer,” Powell told Ars. “It is a camera, but it doesn’t feel like a camera. You need to be really well-coordinated on the day when you’re using it because it bursts for, like, 10 seconds. It doesn’t record constantly because it’s taking so much data. Depending on what the frame rate is, you only get a certain amount of time. So you’re trying to coordinate that with someone trying to fire a 250-year-old piece of technology. If the gun doesn’t go off, if something goes wrong on set, you’ll miss it. Then it takes five minutes to reboot and get ready for the new shot. So a lot of the shoot revolves around the camera; that’s not normally the case.”

Real VR Fishing Devs Explore Hand Tracking With Fishing Haven On Apple Vision Pro

The developers behind Real VR Fishing created an early access Fishing Haven on Apple Vision Pro.

The new app explores hand tracking mechanics for fishing in VR wherever you are, no controllers needed. It’s extremely buggy at the time of writing, but still makes for an interesting exploration with plenty of room to grow. 

For instance, the app begins with multitasking in mixed reality or full VR. You can select where you want to fish while having other apps up. Once you select “go fishing” you exit multitasking and transport to a cozy fishing spot with no other distractions. There are fishing holes across the United States, South Korea, and Japan, which you can unlock as you start reeling fish in. You can examine your rod, reel and tackle while in multitasking mode as well as check on which kinds of fish you have and haven’t caught yet.

Once you’re at your fishing spot, just reach over and grab the rod and make a forceful casting gesture. When a fish strikes, reach over with your other hand and start reeling it in.

Real VR Fishing on Quest headsets has long been one of the best multiplayer experiences, and the title also carries mostly positive reviews on Steam. With Fishing Haven on Vision Pro, the developers have a fresh start and it’s certainly a delight to look over and see a map of all your fishing spots available. It takes just two taps in the open air to go fishing.

We can’t recommend buyers pick up this game just yet, given that it’s early access and features so many bugs at present. That said, the developers have a track record of careful and methodical iterative design and we’ll be watching with interest as they add new features and develop this title further.
