• Processor Wars: How Qualcomm Lost Its Early Lead
    www.technewsworld.com
    Since Microsoft launched Copilot+, the past few months have been a battleground for PC manufacturers. Qualcomm initially had a huge lead, but then AMD and Intel came out with Copilot+ PCs that cut into that advantage.AMD outperformed Intel with a broader line of compliant products, while Intel focused on the premium market. Meanwhile, Qualcomm saw its design wins decline, and the laptop PC market has shifted more in AMDs favor, though Intel remains the dominant player overall.Why didnt we see the big shift to Qualcomm, and what happened to Intel that cost its CEO?Lets break it down and well close with my Product of the Week, which has been keeping my driveway clear for the last week or so.Why Copilot+ PCs Struggled To Gain TractionMicrosoft rushed to market with Copilot+ for PCs with two primary features. One was Cocreator, a derivative of Dall-E, which could have been pretty handy (I use Dall-E a lot these days). The other was Recall, an automatic indexing tool designed to help users find hard-to-locate files. That was pretty much it at launch.However, Microsoft positioned Recall poorly and had to pull it back. Cocreator by itself on a laptop as opposed to a desktop PC or workstation where folks usually mess with graphics turned out to be not very interesting.So, for a time, Qualcomm had only Copilot+ PCs. People werent too excited about Copilot+, and by the time Office began showcasing AI capabilities, PCs from AMD and Intel were available to run it. Unfortunately, Qualcomms brand name wasnt as well known in PCs as AMD or Intel. In addition, Qualcomms product had a compatibility problem that made it largely unacceptable in large companies, so enterprise and large business sales never really emerged outside of trials.A heavy marketing campaign was needed to sell people on the features of running Copilot+ locally. That never emerged, so AI PCs became an AMD and Intel project, with Qualcomm increasingly on the sidelines.What Qualcomm Should Have DoneQualcomm had three advantages in the market: great battery life, the strongest wireless networking of any of the three vendors, and dominance in premium smartphones, which are basically pocket PCs.Qualcomm pushed hard on the AI aspect, which Microsoft fumbled badly. It did mention battery life, but it wasnt successful in making its PCs 5G-capable, which removed that advantage. Finally, it didnt have a better together story to leverage its strong smartphone advantage.Taking on entrenched vendors like AMD and Intel is very difficult, but Qualcomm almost acted like it wasnt that important, even though it acted seriously about this market. In addition, because it had a compatibility problem, it needed to do targeted marketing for the low-hanging fruit: users who wouldnt experience this shortcoming, influencers, small business owners, consultants, attorneys, and others who dont run a lot of custom apps or need to play PC games on their laptops. However, Qualcomm didnt target these users. As a result, while compatibility improved, people tended to lose interest in Qualcomms offer over time.Qualcomm could also have created a halo product that showcased its strengths. The HP Folio PC was an ideal configuration for much of the audience Qualcomm needed to capture, and it launched with an older Snapdragon processor and a 5G modem, making it nearly perfect.Intel displaced Qualcomm with an inferior product (for this use case), and eventually, HP discontinued the Qualcomm-powered PC. Losing the Folio was disappointing because it was my favorite PC of all time. It showcased that with the right internals and effective marketing, a Qualcomm-based PC could have gained traction with users who valued its unique advantages.If both HP and Qualcomm had put some decent marketing behind this laptop, it would have helped build interest in Qualcomms solution, and it would be in a vastly stronger position than it is now.Intels Challenges and Leadership Shake-UpIntel and Microsoft dont see eye to eye often, which has been problematic for both companies execution over the years. Intel seemed to take Microsofts requests as bad suggestions, which forced Microsoft to work with Qualcomm rather than Intel. AMDs reputation was more on the high-performance side, and while AMD executed well, it didnt have anything ready at launch. That gave Qualcomm the huge initial advantage that it failed to capitalize on.This failure appeared to be connected to a prior CEOs decision to reduce the focus on PC technology in favor of smartphones, an effort that failed spectacularly due to poor execution and some questionable behavior by Apple that left Intel out of step with both AMD and Qualcomm.Most recently, Intel lost its CEO partially due to a change in U.S. leadership where the proximity of the Intel CEO to the prior administration might have created some excessive friction and the anticipated loss of U.S. funding for its fab and foundry business. This situation again highlights the markets resistance to significant strategic moves that come at the expense of short-term performance a disappointing reality, given the strategic importance of U.S.-based semiconductor manufacturing.Now Intel has co-CEOs, which is stronger tactically but makes it harder to execute strategically. In addition, Intels CMO support was below where it needed to be, and Intels CTO was more of a COO, leaving the critical CTO underperforming. The CTO sets the vision for strategic moves. Without that, the short-term problems likely contributed significantly to CEO Pat Gelsingers premature departure.Intel needs to appoint a real CTO. Theres a new CMO, but Intel needs to both support and fund him to reform Intels image as a market leader.How AMD Outperformed Intel and QualcommAMDs people just put their heads down and executed, and of the three vendors, it ended up doing the best, even suggesting it would buy Intel. Qualcomm was on the list of companies looking to buy Intel, too. However, Intel is both more complex and far larger than either AMD or Qualcomm, making it unlikely that either company would be comfortable making this acquisition.AMD would be the strongest of the two because it shares both market coverage and x86 technology, meaning it would be better able to step in seamlessly to lead Intel. Still, given how complex Intel is and the cloud its under, it seems unlikely either firm will be able to make an Intel acquisition happen.So, as AI hit, while Qualcomm had the initial potential benefit, AMD has seen the greatest benefit, primarily because it just outexecuted the other two companies.There is something to be said about focus. AMD showed an incredible level of focus over the last decade, which helped it achieve significant growth and benefit from the latest trends. Its recent financial results were impressive.AMD could have displaced Intel during this cycle, but that would have required substantial additional investments. As I noted above, the market isnt rewarding strategies that pull from the present to create a stronger future. AMD played the market well in this cycle.Wrapping Up: Nvidias AI Supremacy and Future in PCsIt has been an interesting few months since Microsoft launched Copilot+. Execution was key, and AMD outperformed Qualcomm and Intel by just sticking to what its good at. However, Nvidia remains the king of AI in hardware, and it also has an Arm-based processor coming, which means it could disrupt the market as AI matures.However, we are still at the very front of the AI wave. By the end of it, I expect both smartphones and PCs will have been replaced by hardware that better addresses the need to interact with AIs in a way we never did with PCs. A massive disruption is coming, and only Nvidia appears truly positioned to drive it. Well, and Huawei, but well save that for another column.Yarbo AI-Powered Snowblower RobotImage Credit: YarboWhile I got my first Yarbo over a year ago, I never put it together because Id broken my back and couldnt mess with something that heavy. As it turned out, there were problems with that first generation, and Yarbo generously offered me the option of an upgrade to a newer unit for a relatively small upgrade cost compared to Yarbos $5,000 sales price.The Yarbo is an AI-driven, GPS-connected yard robot. While I only have configurations for snow blowing and security (it can patrol the outside of your house), depending on the accessories you buy or use, it can also mow your lawn, spread fertilizer, pull a trailer (to stow it), and blow leaves. Mine is a blower only, but it also comes with a trailer hitch and a security head unit if I want it to patrol my yard after the snow melts.Some of the Yarbo yard robots and accessories (Image Credit: Yarbo)Yarbo has sold over 5,000 units to date, making it one of the most successful robots for the outdoors, if not the most successful, this last year. This is an AI/GPS robot, so you dont have to trench and put in boundary wires, like many of the early robotic lawnmowers. It charges inductively, which means you can run and charge it even if you arent home.It does need to see the GPS satellites, which can make placement of the base station difficult (the base station communicates with the Yarbo). My initial base station placement attached to the house didnt work, so I had to move it to one of my sheds. It works fine now, though Im not a fan of having to run an extension cord over my driveway.I noticed that the Yarbo really doesnt like uneven pavers. Neither does my Honda snowblower, but at least I can rock it back to go over the problem areas. You have to set the Yarbo so the blower is a bit higher, which means it isnt going down to the road. I hope a future software patch will address this.Yarbo snowblower at work (Photos by Author)In addition, it comes with winter treads with built-in studs that can tear up an epoxy garage floor like mine, but it has been working okay with the summer treads so far. Running it out of your garage is somewhat problematic anyway since it requires a line of sight to the GPS satellites.It comes with what looks like an Xbox controller that you can use to drive the Yarbo manually and map out the area you want it to service. It also uses a smartphone app. Yarbo does a good job of detecting people and animals, and it will stop if either approaches it. It also has an emergency off switch.I have a large, long driveway, around 3,000 sq. ft. The Yarbo takes about an hour and a half (using half its battery charge) to complete that job. You can tell it where to put the snow, and it will craft a far better plan than I have ever made to clear it all.Although the Yarbo isnt a cheap date, it allows me not to get up early to clear snow in the morning, and it runs autonomously unless it gets into trouble (those damned pavers). Ive really enjoyed setting it up and using it. As a result, Yarbo is my Product of the Week.

  • Does Digital Fitness Tracking Actually Make us Healthier?
    www.discovermagazine.com
    These days, theres a way to track nearly every aspect of fitness and health. You can track your calories, your sleep, your heart rate and the number of steps you take every day. You can track the number of miles youve run, biked or hiked. Often, tracking products advertise health benefits. Ads for fitness-tracking watches like Garmin and Fitbit urge users to tune into your body, unlock human performance, and find your energy. The basic idea is that knowing more about our behavior will lead us to make healthier choices. But some scholars are beginning to question that assumption. Do health metrics actually make us healthier? Or do they have unintended consequences?Digital Tracking Is Mostly HelpfulWearable fitness trackers burst into the mainstream in the late 2000s, when companies like Fitbit and Nike introduced monitors that could sync up with computers and, later, smart phones. Since then, several independent researchers have launched inquiries into how these devices influence physical health, psychological well-being, and behavior. After nearly two decades of research, some questions have been answered. One of the industrys primary claims that tracking your fitness increases your activity level seems to be mostly true.A review of 71 papers studying the phenomenon found that fitness tracking has a positive impact on users' motivation to be physically active. Most of the studies also found that fitness tracking boosted physical activity levels and made users healthier. Yet, these findings have their limitations. Research has shown users who are relatively young (under 50) and already highly active get the most benefit from tracking. In other words, tracking works best for people that already like to exercise.On the other hand, people that are older or less active are more likely to abandon the device. And, for those users, tracking might cause harm. Multiple studies have found that failing to meet tracking goals or underperforming in relation to your peers conjures guilt and frustration. This often leads those users to (you guessed it) abandon the program entirely. The Fitbit is thrown in the bin out of frustration and daily life proceeds.High and Low PerformersAisha Sobey, a postdoctoral scholar at Jesus College Cambridge, recently co-authored a critique of fitness tracking metrics. She argues that fitness tracking research has overemphasized users that benefit from it at the expense of those that dont.It makes people at the bottom do less, she says. We think of this as an unintended consequence.The good news, perhaps, is that these harms may be a result of product design. The most effective fitness tracking platforms hack users' motivation through competition and social reinforcement. For instance, the running-focused app Strava allows users to compare their statistics with friends and followers. For high performers, these features provide a confidence boost. But those at the bottom of the curve feel left behind. To Sobey, its a reminder of the limitations that come with developing a mass-market product for a highly individual experience. Every human has a unique body and mind. The same tool that provides a benefit to one person is bound to harm another.Theres a limit to how personalized these apps can be, she says. Its like, Were going to get you to this end point. You can pick which way you want to go, but the ends remain the same.The Fun in Working OutOne study from Duke assistant professor Jordan Etkin found that, while tracking increases users activity level, it can also undermine users intrinsic motivation. In other words, it encourages users to focus more on reaching goals and less on enjoying the process.By drawing attention to output, measurement can make enjoyable activities feel more like work, Etkin wrote.In her critique, Sobey argues that this detriment stems from the outputs that tracking apps choose to quantify. We cant put something into numbers without making it a goal, she says. Thats fine if youre trying to achieve something, but it distracts from the joy of the thing.Perhaps the antidote to the pitfalls of fitness tracking is, well, more tracking. But, instead of myopically focusing on quantitative metrics, users might make a note, snap a photo or write in a good-old-fashioned journal.

  • How space missions make discoveries on the way to their main destinations
    www.popsci.com
    Europa Clipper will travel 1.8 billion miles (2.9 billion km) to reach Jupiter in April 2030. The spacecraft will orbit Jupiter, and conduct 49 close flybys of Europa. On each orbit, the spacecraft will spend less than a day in the dangerous radiation zone near Europa before zipping back out. Two to three weeks later, it will repeat the process. The spacecraft carries nine science instruments, and a gravity experiment that uses the telecommunications system. All science instruments will operate simultaneously on every pass.Credit: NASA/JPL-Caltech ShareTo get somewhere in outer space, you cant exactly drive in a straight line. Orbits are tricky things, and sending a probe to a faraway planet involves lots of loop-de-loops around other planets on the way. These moves are known as gravity assists, where a spacecraft swings by a massive planet to slingshot itself towards its destination.These trajectory tricks are more than just pit stops on the long journeythey can be prime time to do some bonus science before the spacecrafts main mission. Many solar system missions have made significant discoveries during such flybys, from the earliest probes of the 1970s to BepiColombos recent Mercury flyby and perhaps Europa Clippers Mars flyby happening next month.[ Credit: Scientists explain why BepiColombos mission to Mercury is so tricky ]The planets closest to Earth get the most flyby action: Mars, Venus, and of course, Earth itself. Just last year (and twice before in 2020 and 2021), NASAs Parker Solar Probe dipped by Venus, helping the spacecraft get closer to the Sun than any other human made object before it. One of Parkers cameras was pointed at Venus to track changes in our neighboring planets thick clouds, but it also gave scientists a surpriseat longer wavelengths of light, the camera was able to peer down to Venuss ultra-hot surface. These images revealed strange differences from observations of Venuss surface by the Magellan spacecraft in the 1990s, which may be details missed by the earlier images such as places where the ground is made of different materials.Left: A series of WISPR images of the nightside of Venus from Parker Solar Probes fourth flyby showing near infrared emissions from the surface. In these images, lighter shades represent warmer temperatures and darker shades represent cooler. Right: A combined mosaic of radar images of Venus surface from NASAs Magellan mission, where the brightness indicates radar properties from smooth (dark) to rough (light), and the colors indicate elevation from low (blue) to high (red). Caption Text: NASA. Credit: NASA. The famous Cassini mission to Saturn also made two trips to Venus in 1998 and 1999. Using its various instruments, Cassini measured the amount of dust in the inner solar system, plus ions and other particles streaming off the Sun. It even took some photos of Earths Moon when it passed by us. Since this particular mission was traveling farther out in our solar system, it also did a flyby of Jupiter, spending about six months exploring the giant planet. Cassini revealed a second storm similar to the Great Red Spot, and recorded how small storms globbed on to large storms to make even bigger storms in Jupiters tumultuous atmosphere.This pair of false-color images, made from data obtained by NASAs Cassini spacecraft, shows clouds covering parts of Saturns moon Titan in yellow. Credit: NASA The New Horizons mission provided yet another view of Jupiter on its way to Plutoimages from this particular spacecraft showed lightning at Jupiters poles (something that had before only been seen on Earth), and evidence of a recent collision inside Jupiters very thin rings. New Horizons also took a peek at Jupiters moon Io, looking into its volcanic activity. Get the Popular Science newsletter Breakthroughs, discoveries, and DIY tips sent every weekday.

With a target as big and exciting as Jupiter, scientists turned on the spacecrafts instruments that had been hibernating on the long trip there, using the opportunity to work out any kinks in their software before the real showtime. This is especially critical for a mission like New Horizons, which wasnt actually stopping at its destination; it took data as it zoomed past over the course of a couple months, unlike Cassini which orbited Saturn for almost two decades.This picture shows the asteroids Ida (left) and Gaspra (right) to the same scale. These images were taken by the Galileo spacecraft while enroute to Jupiter. Gaspra was imaged on October 29, 1991 at a range of 3,300 miles (5,300 km). Ida was imaged on August 28, 1993 from a range of 1,900 to 2,400 miles (3,000 to 3,800 km). Both objects are irregular in shape. Gaspra is about 10.5 miles long (17 km), and Ida is 18.6 miles long and 6 to 8 miles wide (9.3 x 12.7 x 29.9 km). These asteroids are just two of the billions of such rocky and metallic objects that orbit the sun mainly between Mars and Jupiter. Caption text: NASA. Credit: NASA/JPL/USGS. Not all targets are as spectacularly large as Jupiter, though. New Horizons also passed by an asteroid named 132524 APLnot for a gravity assist, but just because it happened to be in the neighborhood. Measurements from the spacecraft helped scientists confirm this particular asteroid is made of silicates, nickel, and iron. Another mission did this first, nearly two decades earlier, when the Galileo probe to Jupiter swung by the asteroid Gaspra to produce the first ever close-up image of an asteroid. Galileo then snapped a photo of the asteroid Ida a few years later on its voyage.Credit: NASA When these worlds are so difficult to visitmissions cost millions to billions of dollars, and it takes years to reach the outer solar systemany amount of information we can gain is helpful for scientists. Keep an eye out to see what Europa Clipper finds at Mars next month, and what Psyche (a mission to a metal asteroid) spots on Mars in 2026!

  • A fast radio burst from a dead galaxy puzzles astronomers
    www.sciencenews.org
    A staccato blast of electromagnetic energy has been tracked to an old, dead galaxy for the first time. The discovery supports the idea that there are more ways to produce such flares, called fast radio bursts, than originally thought.Fast radio bursts, or FRBs, are millisecond-long eruptions of intense radio waves. Astronomers have observed thousands of these blasts, but only about 100 have been traced back to their origins, says astronomer Tarraneh Eftekhari of Northwestern University in Evanston, Ill. Almost all of them came from lively neighborhoods full of young stars.From February to July 2024, the CHIME radio telescope array in Canada detected 22 bursts from an FRB dubbed FRB 20240209A. Six of those bursts were also detected nearly 70 kilometers away at a CHIME auxiliary telescope called kniatn klstkmasqt, which means a listening device for outer space in the language of the Upper Similkameen people.Combining those signals let Eftekhari and colleagues triangulate the FRBs location in the sky. Surprisingly, it came from the outskirts of an ancient galaxy, about 11 billion years old, whose star-forming years are long behind it, the team reported in two papers in the Feb. 1 Astrophysical Journal Letters.This image taken with the Gemini observatory in Chile shows the location of the fast radio burst (ellipse) and the ancient galaxy whose borders it came from (center, marked with crosshairs). The galaxy itself is about 2 billion light-years away from Earth, and the FRB is about 130,000 light-years from the galaxy.V. Shah et al/The Astrophysical Journal Letters 2025Astronomers think FRBs come mostly from magnetized stellar corpses called magnetars, which are remnants of supernova explosions. Such supernovas are expected where a lot of stars are actively forming not in an old galaxy, and certainly not so far from the galaxys center.The host galaxy itself is a dead galaxy, says coauthor Vishwangi Shah, an astronomer at McGill University in Montreal. So the question is: How are such energetic signals being produced from such a region of space?Another odd FRB could offer a clue. In 2021, astronomers found an FRB emanating from a globular cluster, a tight ball of mostly old stars in a relatively nearby galaxy. That blast inspired astronomers to think about how old or dead stars could form magnetars. Perhaps magnetars come from white dwarfs collapsing under their own gravity, for example, or out of the wreckage of two neutron stars colliding.The team has applied for observations with the James Webb Space Telescope to see if there is a globular cluster in the spot the new FRB came from.I think that magnetars are still a compelling origin story for FRBs, Eftekhari says. But I think what this discovery is telling us is there are probably multiple ways you can form magnetars that produce FRBs.
