With all of the world talking about Trump's tariffs -- you know, the set of levies on basically the entire world that's set to wreak havoc in the global trade and make your iPhone more expensive -- an important question looms: Has the Trump administration used an AI to calculate those tariffs? It would be unheard of. Trump's "Reciprocal Tariffs" table -- while certainly not definitive at this point -- could turn out to be the most important document of the decade. But the numbers on the table indicate tomfoolery. Without going into intricacies of tariffs for every specific country, the thing is, these tariffs aren't reciprocal, despite Trump calling them so.

With the increasing complexity of mobile device applications, these devices are evolving toward high agility. This shift imposes new demands on mobile sensing, particularly in terms of achieving high accuracy and low latency. Event-based vision has emerged as a disruptive paradigm, offering high temporal resolution, low latency, and energy efficiency, making it well-suited for high-accuracy and low-latency sensing tasks on high-agility platforms. However, the presence of substantial noisy events, the lack of inherent semantic information, and the large data volume pose significant challenges for event-based data processing on resource-constrained mobile devices. This paper surveys the literature over the period 2014-2024, provides a comprehensive overview of event-based mobile sensing systems, covering fundamental principles, event abstraction methods, algorithmic advancements, hardware and software acceleration strategies. We also discuss key applications of event cameras in mobile sensing, including visual odometry, object tracking, optical flow estimation, and 3D reconstruction, while highlighting the challenges associated with event data processing, sensor fusion, and real-time deployment. Furthermore, we outline future research directions, such as improving event camera hardware with advanced optics, leveraging neuromorphic computing for efficient processing, and integrating bio-inspired algorithms to enhance perception. To support ongoing research, we provide an open-source \textit{Online Sheet} with curated resources and recent developments. We hope this survey serves as a valuable reference, facilitating the adoption of event-based vision across diverse applications.

When we reviewed the iPhone 16 Pro last year, Apple Intelligence was barely available. Since then, the iPhone 16 series has benefitted from several new features, apps and improvements. Some (or most) of them were Apple Intelligence features that were teased back at WWDC 2024, months before the iPhone 16 Pro launched. AI features weren't the only changes this time around, with the iPhone 16 getting an entirely new button. The so-called Camera Control wasn't just a simple app shortcut, but an elaborate multifunction button that offered a haptic half-press and the ability to swipe across to adjust camera settings and options.

Apple's iOS 18.4 update offers a variety of new and improved features, but the star of the show may be priority notifications and expanded Apple Intelligence. Although the company's AI-powered technology has received some criticism, Apple remains focused on improving its reach and capabilities. Here are the biggest changes coming to your iPhone and iPad, plus what's new in other software updates rolling out to Apple devices. First up: Apple Intelligence will now display urgent or important notifications in a separate section on the Lock screen, so that you can more easily see what you may have missed. To view all your notifications, simply swipe up on the screen.

Apple's software design strives to be intuitive, but each iteration of iOS contains so many additions and tweaks that it's easy to miss some useful iPhone settings. Apple focused on artificial intelligence when it unveiled iOS 18 in 2024, but there's a lot under the hood that adds to the steady stream of intriguing customizations and lesser-known features from the last few years. Several helpful settings are turned off by default, and it's not immediately obvious how to switch off some annoying features. We're here to help you get the most out of your Apple phone. Once you have things set up the way you want, it's a breeze to copy everything, including settings, when you switch to a new iPhone.

Amazon has sprung a bunch of seasonal deals on shoppers over recent weeks. The retail giant's weeklong Big Spring Sale ran through Monday, March 31, delivering discounts on "end-of-season winter items" and "springtime favorites" across more than 35 categories, per its press release. The Big Spring Sale was Amazon's first major savings event of the year, and unlike its flagship summer Prime Day sale, the deals were not exclusive to Prime members. Prime members did get access to a handful of special offers, which were identified with a "Prime Spring Deal" badge. Is there anything left over from the sale?

Apple has been expanding its presence in the AI and health sectors, aiming to broaden its influence in these rapidly growing fields. Its latest initiative merges these efforts by enhancing the Apple Health app, integrating the product ecosystem's health insights to deliver personalized, actionable advice. In his latest Power On newsletter, Bloomberg correspondent and Apple watcher Mark Gurman shared the details of Project Mulberry, the codename for a completely revamped Health app featuring an AI agent meant to replicate the insights a doctor can give patients based on their biometric data. With Project Mulberry, the Health app will continue to gather data from a user's ecosystem of Apple devices, including their Apple Watch, earbuds, iPhone, and more. The AI coach will then use that information to offer personalized recommendations on how they can improve their health, according to the report.

DJI's debut portable power station can put out 2,200 watts steadily (2,600 watts surge), has two USB-C PD 3.1 ports (140 watts), and boasts DJI's proprietary SDC ports for fast-charging drone batteries. It can juice up phones, run microwaves or small tools, and meet most of your portable power needs, but it's an especially great choice for folks with DJI drones because it can fast-charge most models. It gets a little noisy with several gadgets charging, and cable and bag accessories cost extra, but it still claims a place in our best portable power stations guide. This is one of the best portable power stations for camping or road trips because it's a manageable size. EcoFlow's River 2 Pro has a LiFeP04 battery inside, which is good for 768 watt-hours.
