The Blue Screen of Death is impacting thousands of Windows machines today, as a faulty update from cybersecurity provider CrowdStrike is forcing those machines into a recovery boot loop, so they can't start properly. As reported by The Verge, the issue first affected Australian banks, airlines, and TV broadcasters, but it spread to Europe as the business day started. Among the companies affected, Ryanair had issues with a "third-party IT" impacting flight departures, the FAA is assisting American airlines due to communication issues, Berlin airport is also having difficulties, and so on. On X, CrowdStrike CEO George Kurtz said the company was aware of this issue: “CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts. Mac and Linux hosts are not impacted. This is not a security incident or cyberattack.” https://x.com/George_Kurtz/status/1814235001745027317 Even though the issue seems to have been identified and a fix has been deployed, it seems IT admins will have a busy day. According to The Verge, the "root cause appears to be an update to the kernel level driver that CrowdStrike uses to secure Windows machine." While CrowdStrike has reverted the faulty update, it doesn't appear to help machines that are already presenting the Blue Screen of Death. A Reddit thread mixes possible solutions and workarounds with a lot of humor, as IT admins are already considering this issue a historical day, and fixing this boot loop isn't that simple. That said, if you work on a Mac or Linux machine, you might get double the work this Friday, as you're not affected by this outage. BGR will continue to follow up on this issue, and we'll update the article if we learn more.

There's a new breed of premium robot vacuum and mop combo devices that has finally breathed some life into the somewhat stagnant market. For years, we saw little more than smartphone-like iteration, with new models offering nothing but a power bump and a few tweaks here and there. Now, however, devices like the roborock Qrevo Master robot vacuum and mop have come along and changed the game. Roborock's Qrevo Master is a powerful robot vacuum. It's also an intelligent autonomous mop. But this model's most impressive features aren't immediately apparent until it starts cleaning. That's when you come to appreciate things like the FlexiArm side brush and mop, as well as the auto-fill and auto-cleaning base station. The Qrevo Master is the ultimate roborock robot, and it's currently on sale with a massive $500 discount in a last-minute Prime Day 2024 deal. roborock Qrevo Master Robot Vacuum and Mop, 10000Pa Suction, FlexiArm Design Side Brush & Mop,… Price: $1,099.99 Buy Now I won't bother going over the basics when it comes to the roborock Qrevo Master's specs and features. If you're shopping for an ultra-premium robot vacuum and mop combo device like this one, you obviously already know how these devices work. There are a few key things that are worth highlighting, however. The roborock Qrevo Master has a powerful motor with suction that goes up to 10,000Pa in boost mode. That ranks this model among the most powerful robot vacuums on the market right now. It also has all the bells and whistles you might want when it comes to navigation and AI-powered obstacle avoidance. Plus, it has dual rubber rollers with a decent tangle-free design. In my testing, however, I did notice that dog hair still tends to get wrapped around the ends of the rollers sometimes. Now, let's talk about what makes the roborock Qrevo Master special. First, we have roborock's FlexiArm design, which I love. Most robot vacuum and mop models have stationary side brushes and mopping pads. On the Qrevo Master, the side brush and one of the mop pads are on special arms that extend outward. This way, they can extend into the corners of your floors as well as other hard-to-reach spaces. It's an awesome feature, and it's rare to find a single robot with a side brush and a mop that both extend. roborock Qrevo Master Robot Vacuum and Mop, 10000Pa Suction, FlexiArm Design Side Brush & Mop,… Price: $1,099.99 Buy Now The other thing I absolutely love about the roborock Qrevo Master is roborock's new Multifunction Dock 3.0. This new base station from roborock has two large tanks of water, one clean and one dirty. As the robot mops, it returns to the base station to have the dirty water sucked out. Then, the clean water tank refills the robot so it can go back to mopping. When the roborock Qrevo Master is finished cleaning, the base station automatically washes the mop pads. It also dries them with 113-degree F hot air. That way, you don't have to worry about smells or bacteria. There's also a third space in the Multifunction Dock 3.0 underneath the water tanks for roborock's extra-large debris bag. The base station sucks all of the dirt, dust, and hair out of the robot and stores it in a bag. It holds up to seven weeks' worth of dirt, or even more, depending on how dirty your floors get. That way, you only have to worry about changing the bag every 1.5-2 months. roborock Qrevo Master Robot Vacuum and Mop, 10000Pa Suction, FlexiArm Design Side Brush & Mop,… Price: $1,099.99 Buy Now Now, we come to what is really the only downside with the roborock Qrevo Master: the price tag. At $1,599.99, this model is one of the most expensive high-end robot vacuum and mop combo devices you can buy. Needless to say, all of that power and all of those awesome cutting-edge features come at a price. Still, if it's within your budget, you're not going to find a better flagship robot vacuum than the roborock Qrevo Master. It's worth noting that this model is currently on sale with a massive $500 discount for Prime Day 2024. That drops the price to $1,099.99, which is an all-time low for the Qrevo Master. Since Prime Day is technically over, however, I don't expect this deal to stick around much longer. If you've been on the fence but the high price was making you balk, now is absolutely the time to pull the trigger.

Lunar exploration equipment at any future lunar base is in danger from debris blasted toward it by subsequent lunar landers. This danger isn’t just theoretical – Surveyor III was a lander during the Apollo era that was damaged by Apollo 12’s descent rocket and returned to Earth for closer examination. Plenty of ideas have been put forward to limit this risk, and we’ve reported on many of them, from constructing landing pads out of melted regolith to 3D printing a blast shield out of available materials. But a new paper from researchers in Switzerland suggests a much simpler idea – why not just build a blast wall by stacking a bunch of rocks together? On the Moon, that task isn’t as simple as it sounds. It would require an autonomous excavator to assess the rocks, collect them, and stack them on top of each other so that they wouldn’t fall over. Depending on the size of the rocks, that task could be completed successfully by a toddler, but for a robot, it remained in the realm of science fiction, at least until recently. Another paper by some of the same co-authors described an autonomous boulder-stacking robot for use in construction projects on Earth. In it, they showed a control algorithm that could successfully stack a rock wall together using medium-sized boulders entirely autonomously. Applying it to lunar construction seemed like the next obvious step.  Video of the autonomous boulder stacking method in use on Earth.Credit – ETH Zurich YouTube Channel But first, an excavator would have to make sure there were enough boulders around to build the wall effectively. In the paper, the authors use data from the Lunar Reconnaissance Orbiter to research the distribution of boulders at two potential landing sites – the Shackleton-Henson Connecting Ridge and the Aristarchus Plateau. They also extrapolate sizes of smaller boulders based on the limits of LRO’s resolution and the distribution law of boulder sizes. Final confirmation came in the form of rock abundance data from another instrument on LRO, with their final estimates agreeing that there should be enough loose material for an autonomous excavator to build a blast wall using locally sourced boulders successfully. Calculating the amount of material needed to build the blast shield was actually a precursor step to confirming enough boulders were available. It was also necessary for another important calculation – understanding how much energy this process would take compared to alternative solutions of processed stone walls or microwave-heated landing pads. According to the author’s calculations, stacking existing stones is two to three times less energy-intensive than alternatives. That’s not to say there aren’t still hurdles to overcome. The most obvious is the lack of an autonomous excavator capable of operating on the Moon. The one used in the Earth-bound experiments was prohibitively large, and designing a system for use on the Lunar surface is notoriously difficult, with the radiation and the electrostatically charged dust particles. Those electrostatically charged particles could also prove a problem, but further modeling is needed to understand whether lunar boulders would be affected by considerable dust accumulation. Fraser discusses the need for our return to the Moon. The idea itself is still relatively new, and it does have a lot going for it, given its advantages and the proof of concept demonstration already completed on Earth. So, while there are currently no plans to set up an autonomously constructed rock wall, there is a decent possibility that the idea, or something similar to it, could be picked up as part of the Artemis mission infrastructure. At least the Artemis mission designers will have plenty of potential solutions to this problem, no matter their choice.
