In response to the security incident, PayPal has reset the passwords of all affected accounts. PayPal Provides Recommendations but Delays Reporting the Incident PayPal offered free identity monitoring services to affected accounts–but is this really enough to ensure online safety? Since the accounts didn’t have two-factor authentication (2FA) enabled, cybercriminals were able to break into and easily compromise them.

After the dough has been refrigerated for 15-20 minutes, it should come out of the refrigerator clean. The filling can be seen through a small hole in the top of the cookie, which has been dusted with powdered sugar. It makes a delicious accompaniment to raspberries, lemon curd, or chocolate hazelnut spread and is crispy on the outside and soft on the inside. Linzer Cookies can be cut into a daisy, a heart, a round, or even a teddy bear. Almond cookies are sandwiched between raspberry preserves, lemon curds, or chocolate spreads to create a tasty filling. Linzer cookies are delicate almond cookies that have been cut into intricate shapes. You can also place them in a container with a piece of parchment paper between the cookies to help absorb any moisture. To keep linzer cookies crisp, you can store them in an airtight container in a cool, dry place. Alternatively, store cookies unassembled for up to 5 days and dust and fill when ready to serve. Cookies that have been assembled and tightly wrapped in plastic wrap can be stored at room temperature for three days. Place the cutouts on the tops of the cookies, and then dust them with confectioner’s sugar to make the cookie more like a cake. Toasting the almond flour for this recipe adds a touch of extra flavor to this recipe. After 10-15 minutes, a very light golden haze can be found around the edges. Divide each disc of dough into two equal pieces of wax paper, one 1/8 inch thick. Divide the dough into four portions and wrap them in plastic wrap before flattening them. The bottom layer of shortbread has a small cutout in the center that allows the jam layer to be visible. With citrus and almond flavors, this Linzer Cookies recipe is not only delicious, but also jam-packed. It is a sandwich cookie based on the Austrian classic cake Linzer torte. When using almond flour, you may need to add a little extra liquid to the dough to get the right consistency. The almond flour will give the tarts a nutty flavor and a slightly denser texture. Almond flour can be used in linzer tarts in place of all-purpose flour. Linzer tarts are named after the city of Linz, Austria, where they are said to have originated. The dough is usually made with flour, sugar, butter, and eggs. Linzer tarts are a type of tart made with a shortcrust pastry dough and filled with jam. And, like most gadgets nowadays, you'll need to bring your own power adapter, as only the USB-C cable is provided in the box. You'll need to have a MagSafe-compatible phone case for the 622 or any magnetic battery to attach properly.The Anker products aren't officially compatible with Apple's MagSafe standard, so they charge more slowly than those pricier Apple-sanctioned products.Get These Prime Day Deals Under $25 Before They're Gone.Best Target Circle Week Deals: Discounts on Everyday Essentials, Electronics and More.Big Prime Day Deals Still Available on Apple iPads, MacBooks, AirPods and More.Amazon Prime Day 2023 Live Blog: Remaining Deals Vetted by Experts.Prime Day Is Over, but These Deals Are Still Available - For Now.There’s nothing major wrong with it other than it gives about half the charge of third-party brands at double the cost. Sadly, the Apple MagSafe Battery Pack is the first Apple product I’ve ever returned. If this product had come out simultaneously with the iPhone 12 without competitors, it might be a different story, but charging power is charging power. So if you have a budget of $100 to spend, grab two of them. So what’s the final verdict on the Apple MagSafe Battery vs Anker Magnetic Battery Pack? Unless you want to charge with a lightning cable and like the iPhone battery widget integration, I can’t recommend it over the Anker model. Apple logo on the back, with quality and reputation that go with it.The Anker Magnetic Battery Pack charges over USB-C, and that’s a significant benefit of using it. My MacBook Air charges over USB-C, my iPad Air charges over USB-C, my Logitech MX3 charges over USB-C, and my AirPods Pro charges over wireless charging. Because of MagSafe, I want to go to USB-C for everything wired charging. While this might seem like a trivial thing, I am over devices that charge by lightning. It might be the best one if you want the whole Apple experience, but it’s double the price of the Anker Magnetic Battery Pack. Anker Magnetic Battery PackĪfter spending some time with Apple’s MagSafe battery pack, I can firmly say that it’s not the best value. The underside of Apple’s battery case is slight softer than Anker’s, but if you’re using a case, you won’t likely notice a difference. Both will fit the iPhone 12 mini as well as the iPhone 12 Pro Max. Sizeīoth battery packs are compatible with each other in physical size. So for double the price, you’re getting a much lower capacity battery. Apple’s MagSafe battery is 11.13Wh, where the Anker model is 18.5Wh. CapacityĬapacity is where the problems crop up for Apple’s MagSafe battery. Is that feature worth spending an extra $50 on? It’s hard to justify, in my opinion. For obvious reasons, none of the third-party options can deliver that. On the Apple MagSafe battery, there is a widget showing the current charge of the battery. The second thing to consider is integration with the iPhone. Apple’s MagSafe battery is $99, so right away, that’s a reason to look elsewhere. Both the Anker and the Charge Fast models are less than $50. One of the biggest considerations when choosing a MagSafe battery pack is the price. In practice, I’ve never had an issue with charging from the non-Apple ones. The other options are MagSafe compatible, though. Anker Magnetic Battery Packīefore we look at the key features, one thing to keep in mind is that only Apple’s battery is MagSafe certified. Now that I have three options, which one will be my go-to model for trips and days when I’ll be away from home most of the day? Apple MagSafe Battery vs. I own a handful of models similar to these, and for extended trips, I always keep one in my bag.įor shorter trips, I am going to rely on MagSafe batteries from now on. If you want the absolute biggest external battery you can find, you’ll want to go with an actual external battery that you’ll plug your iPhone into. One of the benefits of MagSafe is that you won’t need to use a cable to charge your iPhone. So it’s not a matter of if you’ll need an external battery, but which one. The truth is that if you travel with the iPhone 12 mini, you’ll need external batteries to make it through the day with normal to heavy usage. While I haven’t traveled as much as I usually would since the iPhone 12 mini was released, I’ve done enough to feel how it functions when not at my desk. Anker Magnetic Battery PackĪs I’ve mentioned in my iPhone 12 mini diary, the battery in my iPhone doesn’t last nearly as long as it did when I was on the “Max” lineup, but that’s the trade-off you make to have an iPhone you can fit in your pocket. “I’d advise not going any taller than you have to, both to save on expenses and to limit the shrinking, enclosing effect fences can have on a space,” Lenhart says. How tall can I make my privacy fence?įences that are six feet tall should block most views from the ground level. For larger yards, he suggests making use of natural greenery, like trees, to keep unwanted eyes from infiltrating your space. In general, he says privacy fences make the most sense on small properties, like town house gardens. “As a rule of thumb, fences should be at least two inches off the ground to let critters the freedom to move between properties,” Fargion explains. Privacy fences cut the land into lots, which can be problematic for the bugs, insects, and other wildlife that live there. This doesn’t mean privacy fences are necessarily a bad idea, just that there are a few considerations to take into account before getting started. “From an ecological and natural point of view, privacy fences are the least desirable element in the landscape,” says Jonathan Fargion, a landscape designer based in New York City. Here, a guide to building backyard landscaping and a privacy fence-whether you use a pergola or a trellis-to keep onlookers out and a peace of mind in. “A privacy fence does all the work of a typical fence-indicating boundaries and keeping people and animals in or out-while also blocking views into the yard,” says Kevin Lenhart, a landscape designer and design director at Yardzen, one of the nation’s largest online landscape platforms. Luckily, clever retaining wall ideas and privacy fence ideas (some are even DIY landscaping designs) can ensure your backyard is the secluded oasis you want it to be. Hidden areas, made with privacy screening, create a sense of mystery, as you do not see all of the garden at once. “A garden should, at its best, connect us to nature, and this is simpler to do when you can relax in a peaceful setting. “Privacy fencing, either along a property line or around a specific area in your garden, creates a sense of sanctuary, seclusion, and peacefulness,” says Janice Parker, a landscape architect based in Greenwich, Connecticut. Your home should be the place where you feel the most relaxed, but without some privacy fence ideas it’s hard to truly unwind if you feel like you’ve got unwanted eyes peeking over your shoulder. If you don’t want to add these Converters and Comparers to all of your projects, you can use my small library, TinyHelpers.EntityFrameworkCore, that is available on GitHub and NuGet. Note that, even with this solution, we still don’t have support for migrations, so if we try to create a migration for a class that contains a DateOnly or TimeOnly property, we’ll get an InvalidOperationException and, on the other hand, if we scaffold a table that has a date or time column, they will be mapped to DateTime and TimeSpan types, respectively. Time is a TimeOnly property and time on database Date is a DateOnly property and date on database Protected override void OnModelCreating(ModelBuilder modelBuilder) We just need to add the converters and the comparers in the OnModelCreating method of the DbContext: So, now we can easily enable support for DateOnly and TimeOnly properties in our classes, mapping columns that use the date and time types. In the code above we have defined also the Value Compares to correctly handle data comparison. In the same way, TimeOnl圜onverter converts a TimeOnly properties to and from a TimeSpan.

Public class ApplicationUser : IdentityUser Net Core 3.1 it seems required to use, for user management, a class inheriting from IdentityUser, which is in namespace. Net Core 2.x it was possible to use the context created from scaffolding for everything (user auth and management, normal db operations on other tables) instead in. This command scaffolds a DbContext and entity type classes for a specified database. In Helpers we can add a AppSettings class that will be useful for user auth: Our models folder is filled with classes that are mapped to the db tables:Īdd in the solution 2 folders, Services and Helpers.

The lack of atmosphere does change some things a bit, but for the most part it’s more about making sure the tech can do its thing safely. Luckily, light works the same, for the most part anyway, on the moon as it does here on Earth. This, as well as its use of frequency-modulated continuous wave tech instead of flash or other lidar methods, means it is robust to interference from bright sunlight. So when it scans a street, it knows that one shape is moving towards it at 30 MPH, while another is moving away at five MPH and others are standing still relative to the sensor’s own movement. That’s what NASA on for the last couple years, funded through the Space Technology Mission Directorate’s “Early Career Initiative,” which since its launch in 2019 aims to “Invigorate NASA’s technological base and best practices by partnering early career NASA leaders with world class external innovators.” In this case that innovator is Aeva, which is better known for its automotive lidar and perception systems.Īeva has an advantage over many such systems in the fact that its lidar, in addition to capturing the range of a given point, will also capture its velocity vector. What NASA was looking for, however, was a unit small enough to be mounted on an astronaut’s backpack or to a rover, yet capable of scanning the terrain and producing a detailed map in real time - and determining exactly where it was in it.Ĭoncept image of a backpack-mounted lidar. Lidar provides an option for mapping even in darkness or bright sunlight, and it’s already used in landers and other instruments for this purpose. This area is a target for lunar operations due to a good deal of water below the surface, but we just don’t have a good idea of what the surface looks like in detail. For example, at the south pole of the moon, the fixed angle of the sun results in there being deep shadows that are never illuminated and brightly baked highlights that you need to careful how you look at. This is necessary because for now, we have no GPS-type tech on the moon, Mars or any other planet, and although we have high-resolution imagery of the surface from orbit, that’s not always enough to navigate by. The project is called KNaCK, or Kinematic Navigation and Cartography Knapsack, and it’s meant to act as a sort of hyperaccurate dead reckoning system based on simultaneous location and mapping (SLAM) concepts. Without GPS, navigation and mapping is a lot harder - and NASA is working with lidar company Aeva to create a tool that scans the terrain when ordinary cameras and satellite instruments won’t cut it. As humanity prepares to return to the moon (“to stay,” as they remind us constantly), there’s a lot of infrastructure that needs to be built to make sure astronauts are safe and productive on the lunar surface. |
