Keeping our house clean is almost as necessary as a real pain in the ass. For this reason, any technological help that we can have for this is always welcome and there are few things more useful than a robot vacuum cleaner. Do you want one without costing you a fortune? Well, keep an eye on this iLife A30 Pro: on AliExpress it comes out 84.03 euros if we use the coupon ‘ESA13‘. At this price, it’s hard to find something better. ILIFE A30 Pro Vacuum Cleaner and Mop, Self-Emptying Station for 60 Days, 5000Pa Suction, LiDAR Navigation, 2.4G WiFi/App The price could vary. We earn commission from these links A robot vacuum cleaner that is surprising for its price As we have been telling you since yesterday, the AliExpress Anniversary It’s back with a vengeance this year. There are really powerful offers and this iLife robot vacuum cleaner is a more than perfect example to illustrate them. If we take a look in stores like amazon either Leroy Merlin, The price of this model is around 200 euros. For this reason, this AliExpress offer is a real treat, but even more so if we take a look at what this iLife A30 Pro offers. The first thing is the suction power, which is 5,000 Pa. Translated into practice, it is more than enough to carry away dust, crumbs and even animal hairthe things that most often populate the floors or carpets of our homes. Plus, it also scrubs. It is also worth stopping a little while browsing. It has a LiDAR system that It is not usually present in robot vacuum cleaners in this price rangewhich is already a point in its favor. Thanks to it, you will move well between rooms and overcome the obstacles you encounter, avoiding those uncomfortable headbutts that these types of devices sometimes cause. Beyond all of the above, perhaps one of its greatest assets is its self-emptying base. This will clean the robot’s tank and, as the dirt ends up in a 2.5 liter capacity bag, It’s enough so that we don’t have to do anything for about 6 or 7 weeks. And it has plenty of autonomy, since it offers up to 180 minutes if we use its gentle mode. It is reduced if we use more suction power, of course. This iLife A30 Pro does not seek to be the best robot vacuum cleaner on the market, but it is one of the best options we can buy if we want to spend as little as possible. For less than 90 euros, It is very difficult for us to find something better. And in fact, it is rocking it on AliExpress: it has more than 10,000 sales and an almost perfect average rating.

Humanity has been using the Earth’s magnetic field as a navigation guide. Some researchers want to retire it

by

In recent decades, GPS has become part of our day to day. If it is a military technology, the global positioning system has been guided by roads, forests and seas, in the city and in the mountain, but always with an important limitation, access to satellites that place our navigation devices. That could change. Magnav. Thanks to magnetic navigation systems or Magnav, and more specifically to a new development that uses a quantum adjustment system that promises more precise navigation. A navigation, in addition, immune to interference, accidental or caused, which allows significantly reducing satellite navigation dependence. Magnav systems (Magnetic-Anomaly Navigation) o Navigation by magnetic anomaly are based on the fact that the Earth’s magnetic field It is not uniform. That is why it is possible to use a magnetometer that indicates our position by measuring small variations in the magnetic field of the planet. Use the Earth’s magnetic field as Navigation reference It is not something new but something we have been doing since the invention of the compass, but the new system promises to achieve unusual precision. That’s where the quantum dimension of the new system comes into play. Navigation “quantum”? The new technology, They explain their developersis based on the use of quantum magnetometers that combine a noise elimination system with a cartographic algorithm. The magnetometers are based on the optical detection of the precession of the atomic spin, for which they use a steam cell that contains rubidium atoms, They detail. This technology opens the door to measure the magnetic field of the Earth with greater precision, which translates into a better capacity to locate ourselves on the map. All this, they also highlight, in a device small enough to be used in autonomous vehicles or in fixed wing drones. Q-ctrl. Behind this system is an Australian company, Q-Ctrl (name that refers to “Quantum Control”) The company emerged in 2017 Like a Spin-off of the quantum science group of the University of Sydney. By land and air. RecieBy land and air. Recently, the team responsible for this system put it to the test. With satisfactory results: the device obtained errors in the measurements up to 46 times less than the inertial navigation systems usually used as a complement to the satellite. The measurements were made on flights at a height of 19,000 feet, in which it was also possible to fly with a total error in the 22 -meter trip, 0.006% of the distance traveled. The results were “consistently” at least 11 times better than those obtained with inertial systems. The team responsible for the development of the new tool has published some details in an article. The article has not passed the pairs review filter but can be found freely Through the repository Arxiv. Substitute or complement. Satellite navigation systems are central today and this is precisely its weak point: the emergence of GPS signals puts both commercial routes and passenger transport, but it could also put into check military operations in cases of armed conflict. The interception of these signals can therefore be used as well as a commercial and war weapon. We have various tools that allow satellite navigation to attend, but few systems can at the same time have the accuracy of these without depending on them. That is why having alternative mechanisms of high precision can be more precise than ever.

The magnetic north pole has been moving rapidly. This is how navigation instruments follow the step

by

What do we talk about when we talk about the North Pole? The truth is that it depends since, on our planet we can distinguish two key geographical points that respond to this name, but with different “surname.” They are the magnetic north pole and the geographical north pole. Distinguishing them is key because only one of them has a fixed location while the other wanders in their proximity. But, in addition, it makes it faster. Reviewing the location. The new year has been released With an update that has gone more or less unnoticed but that is of the utmost importance: it is the world magnetic model (WMM) of 2025. The revision of the model not only includes the information about its current position but also of its displacements planned in the next five years . Accelerated movement. We have known for a long time that the magnetic north pole changes location and we know that the cause is in the changes in the magnetic field of the planet, a field generated by the connective iron movements of the interior of our planet. What is most striking is that, during the last decades the displacement of the magnetic northern pole It has accelerated. If for 300 years this point ranged between the islands located north of Canada, since the end of the 20th century and especially during the new century, the speed of displacement of this markedly accelerated. Now the magnetic north has already exceeded the geographical north and is closer to Siberia than from Canada. “The current behavior of the magnetic north is something we had never seen before. (…) In recent years he accelerated towards Siberia, increasing speed every year until about five, when he suddenly seized 50 to 35 km per year, ” explained in a press release William Brown, of the British Geological Survey (BGS), one of the institutions in charge of the development of the model. The world magnetic model. The model It is the result of the collaboration between the National Environmental Information Centers (NCEI) of the NOAA (National Oceanic and Atmospheric Administration) American and the BGS, as well as two intelligence agencies on both sides of the Atlantic. The model is used in various contexts, from aviation to commercial GPS and applications that use compasses on our mobile. The model includes a series of maps that not only indicate the location of the magnetic north but also mapped the changes in the Earth’s magnetic field, allowing to know the behavior of compasses at each point of the northern hemisphere. More precision. The latest version of the model, WMM2025will help improve navigation, especially in long -distance tours. As explained by the BGS, a trip between South Africa and the United Kingdom, using the old model, would imply a slight deviation of a degree on the way. The problem is that, over 8,500 kilometers, this very small deviation results in an error of 150 kilometers. The new model allows you to approach centimeters from the destination point. The version also incorporates a novelty: a high resolution map that will accompany the “standard” and that can be used in contexts where greater precision is required. This version has a 300 km resolution in Ecuador, notably higher than the 3,300 km resolution in the standard version. The next update. The WMM model is updated every five years, which means that we will have a new version in 2030, WMM2030. This assuming that I do not know any unexpected change in the speed or direction of the displacement that justifies an extraordinary review of the model.

Google finally fixes the navigation gesture that was broken on older Pixels when updating them to Android 15

by

Google is already working in the next Pixel 10 and Pixel 11 as was learned yesterday from an internal source. Now one of the bugs that were generated has been marked as corrected when updating old Pixels to the latest version of Android, precisely 15. This version was deployed to the new Pixel 9 like the rest of the old Pixels such as the Pixel 8 series in the middle of October. These types of updates make you enjoy the news and those new experiences who spend their daily lives better with a smartphone, a tablet or a smart watch. But not everything always goes well and with this deployment, users of the old Pixels found themselves with a very strange bug: Swiping in from the right side of the phone did not activate the back gesture, so the interaction experience failed severely with that update to Android 15. Now the issue has been marked as corrected in Issue Trackerthe web space that Google uses to record all bugs or errors on its mobile devices and where you can review the correction of errors. Pixel 7 Pro Alvarez del Vayo The Free Android In fact, a Google employee has stated that the solution will be deployed in a new imminent update of Pixel phones so that normal use of the phone can be resumed. First reported on a Pixel 8 Pro so that it would soon be confirmed in other models by more users. The error affected the gestures that are applied from both sides, not only the right one as has now been confirmed as solved since Issue Tracker. And it is a quite serious problem for the mobile gesture experience, since it has prevented the ability to navigate backwards. The only solution that had been given until now was use the navigation bar with its three buttons, but you can almost say that it is an almost retro experience so that moving with gestures is tremendously simple. The update with the back gesture fix will be deployed in the month of Februaryright in the first weeks, so any of the old Pixels can be used again as it has always been done with an error that can generate a lot of frustration according to what it maintains GSMArena.
