Installing a window air conditioner is typically a straightforward DIY process that can quickly transform a muggy room into a much more comfortable space. 

If you have any questions about your specific model -- or the window where you're planning to install it -- consider hiring a professional to help. Otherwise, we'll walk through the basic steps to set up a window air conditioner below.

Installing a window air conditioner

To come up with this basic set-up guide, I reviewed the installation instructions from three different window AC units: the LG LW5016, the Toshiba RAC-WK0511CMU and the GE AKLK14. Keep in mind that some details may vary from unit to unit, so always check your user manual before you begin installing a window air conditioner.

For a window AC installation, you'll need a screwdriver (some guides specify Phillips head, others flathead -- and some both), a level, a pencil, a tape measure and scissors. 

Most window AC units come with mounting panels and weatherstripping material in addition to the air conditioner. These accessories help create a seal designed to block the cool air from leaking outside and the hot air from leaking in. 

Step 1: Connect the panels to the air conditioner

Once you have the required tools, unbox the air conditioner, along with all of the accessories and hardware. Next, attach the panels to the AC unit. Side panels that open to a desired size are common. Your unit might also have top and bottom panels. Depending on the unit you have, this may require hardware and a screwdriver. Other panels slide into place without requiring screws. 

Step 2: Seal the window 

Use the included weatherstripping material to create a seal on the window. Typically, this material has an adhesive side for easy installation. Cut the strip to the desired size with scissors and place on the window to restrict air leakage. 

Step 3: Install the air conditioner

Lastly, attach the air conditioner to the window. This step will likely require a screwdriver and hardware to make sure the AC unit is securely connected to the window. Follow the manufacturer guidelines closely here to ensure the air conditioner is positioned correctly. The panels should cover any space that would otherwise be open to the elements; the weatherstripping should create a tight seal between the window and the air conditioner. 

Final thoughts

Before you buy your window air conditioner, make sure you select the right size unit for your room to allow it to function optimally. Once you've made your selection and set up your AC unit, there are some other things to consider. In order to ensure your air conditioner lasts as long as possible, make sure to clean it regularly. Also be aware of these signs that your window unit might need a repair.

And, if you aren't sold on a window air conditioner for your space, consider a portable AC unit instead. They're more versatile than a window unit because they can travel with you from room to room as needed.

Facebook agreed to pay billions of dollars extra on top of an initial fine sought by the Federal Trade Commission in 2019 to protect CEO Mark Zuckerberg from personal liability related to a massive data leak probe, shareholders allege in a pair of lawsuits made public on Tuesday.

In lawsuits filed last month in Delaware's Chancery Court, two groups of shareholders cited internal discussions among Facebook's board members in alleging they authorized a $4.9 billion overpayment of the fine to shield Zuckerberg, the company's co-founder and largest stockholder, and COO Sheryl Sandberg. The lawsuits were reported earlier by Politico.

"Zuckerberg, Sandberg and other Facebook directors agreed to authorize a multi-billion settlement with the FTC as an express quid pro quo to protect Zuckerberg from being named in the FTC's complaint, made subject to personal liability, or even required to sit for a deposition," one of the suits alleged.

The FTC started investigating Facebook in 2018 after revelations surfaced that Cambridge Analytica, a UK political consultancy, accessed data from up to 87 million Facebook users without their permission. The agency's probe focused on whether Facebook violated a legal agreement it had with the US government to keep its users' data private.

Zuckerberg was named as a co-defendant in the action in a draft complaint the FTC sent to Facebook in early 2019, the partially redacted lawsuit alleges. The complaint alleges that Facebook's lawyers had determined the company faced a fine closer to $107 million but the company's board agreed to pay a $5 billion penalty in exchange for keeping Zuckerberg and Sandberg from being named in the settlement.

The lawsuit notes that on the same day the FTC settlement was announced, the Securities and Exchange Commission announced it would fine Facebook $100 million as part of a settlement tied to its probe into the social network's handling of the data.

"The Board has never provided a serious check on Zuckerberg's unfettered authority," shareholders said in one of the lawsuits. "Instead, it has enabled him, defended him and paid billions of dollars from Facebook's corporate coffers to make his problems go away."

Facebook and the FTC didn't immediately respond to requests for comment.

Scientists have come up with a device that harvests sweat from your fingertip to generate power. The flexible, thin strip wraps around the tip of a finger like a Band-Aid and converts chemicals found in human sweat into small amounts of electrical energy. Fingers constantly produce sweat, so the device can work without the wearer moving a muscle.

"By using the sweat on the fingertip -- which flows out naturally regardless of where you are or what you're doing -- this technology provides a net gain in energy with no effort from the user," said Joseph Wang, a professor of nanoengineering at UC San Diego and co-author of a paper describing the product, published Tuesday in the journal Joule.

It's common for self-powered wearable systems that rely on bioenergy harvesters to require excessive inputs of energy. But because this device doesn't require any physical input from the wearer to work, it's "a step forward to making wearables more practical, convenient and accessible for the everyday person," study co-author Lu Yin, a nanoengineering Ph.D. student at UC San Diego, said in a statement. UC San Diego researchers previously worked on temporary tattoos that turn sweat to power. 

While the new product can produce power, it's not time to kick your tangly cords and finicky electrical outlets to the curb just yet. The device can potentially power lower-power electronics that operate in the milliwatt range, such as a wristwatch, but it's not yet suitable for continuously powering high-performance electronics such as smartphones, the researchers say. 

"Our goal is to make this a practical device," Yin said. "We want to show that this is not just another cool thing that can generate a small amount of energy and then that's it. We can actually use the energy to power useful electronics such as sensors and displays."

Fingertips, each packed with more than a thousand sweat glands, can produce between 100 to 1,000 times more sweat than most other body parts. It might be hard to notice how sweaty they are, though, since the sweat typically evaporates from fingertips as soon as it comes out. This new device collects it before it can. 

The device was built to be highly absorbent. First, sweat is absorbed and converted into energy by a padding of carbon foam electrodes. The electrodes have enzymes that trigger chemical reactions between lactate and oxygen molecules in sweat, generating electricity. There's also a chip underneath the electrodes made of piezoelectric material that generates more energy when pressed.

Electrical energy is stored in a small capacitor as a wearer sweats or presses on it. It can then be discharged to fuel low-powered devices.  

As a subject slept for 10 hours with the device on a fingertip, the wearable collected 400 millijoules of energy, which is enough to provide 24 hours worth of power to an electronic wristwatch (but not a smartwatch). The researchers note that strapping devices to additional fingertips would generate even more energy. But I'm still processing the news about how many sweat glands are on ONE of my fingers, much less 10. 

The battle rages on. A week before AMD was scheduled to deliver the details about its new Navi-generation midrange graphics cards, the Radeon RX 5700 and RX 5700 XT, rival Nvidia announced bumped-up "Super" versions of its directly competing RTX 2060 and RTX 2070 at slightly lower prices than AMD had publicly revealed for its new cards. So two days prior to its rollout, AMD dropped the prices on its cards to match: $349 for the 5700, $399 for the XT version and $449 for the 50th anniversary edition version of the 5700 XT.

While 1080p gaming remains the most popular resolution, 1440p (2,560 x 1,440) is the next enthusiast frontier, and both companies want a piece of it -- so much so that they've entered into a price war before their cards have even shipped. The 5700 series is available now.

But AMD's entering the battle with a revamped processor architecture, hoping to break the perception of being the "value" option rather than the performance leader. And based on our preliminary testing, the RX 5700 does seem to deliver better frame rates across various benchmarks than the RTX 2060, at least at 1080p. Unfortunately, we don't have an RTX 2060 Super yet for comparison. 

While the Radeon VII remains the flagship card in AMD's gaming line, its technology straddles generations -- it's built on AMD's 7nm process, but it doesn't have the upgraded memory architecture, PCIe 4 support, more efficient compute-unit design, lower power draw, quiet operation and more that comprises AMD's "RDNA" architecture for the Navi generation. With Navi, AMD moves from using HBM2 (high-bandwidth memory) to the more widely used GDDR6 for its consumer products.

AMD positions both cards as 1440p contenders, but the extra $50 buys you the ability to play at a higher-quality setting. Across the board, we saw roughly a 10% increase in frame rates from the 5700 to the 5700 XT at 1440p, and both delivered average frame rates of more than 70fps overall.

And the cards are very quiet. They are bigger and do require more power than the RTX 2060 -- it uses similar connections to the 2080 Ti, and they're both bigger than the 2060 -- but the 2060 Super has increased power requirements as well. In addition to differences in the number of compute units (the rasterization engine of a graphics processor)  and clock speeds, the 5700 and 5700 XT differ by look. The 5700 XT has a less featureless surface and the logo glows red, plus only part of the internal circuit board peeps out; the 5700's entire underside is exposed.

They do have the same connectors on the back, however, 3 DisplayPort 1.4 and 1 HDMI 2.0b. I do miss having a USB-C port back there like on an Nvidia card since they're still pretty rare in desktop systems. 

Along with the cards, AMD revved its Adrenalin utility software with a few new features, most notably Radeon Image Sharpening (RIS) and Anti-lag. RIS does what Nvidia's DLSS is intended to (without the AI), provide a better image when playing at higher resolutions -- e.g., displaying in 1440p while the graphics card is only working with 1080p, to minimize the performance hit of a higher resolution. (My testing was interrupted by a network outage in our lab, so I was unable to download some games I wanted for visual comparison.) 

Specifically, RIS uses a technique called contrast-adaptive sharpening to improve detail on textures with less-defined edges. (CAS is similar to what the new Texture tool in Lightroom does.) There are two flavors: game developers can integrate support or you can toggle it in Adrenalin to apply it on the fly for unsupported games. The former will deliver better results. As far as I could tell, there was no performance penalty for applying it in the driver.

Anti-lag essentially works to better sync the CPU and GPU so there are fewer wasted cycles between the time you click the mouse and the display responds -- AMD claims about 30% improvement.

LG left the smartphone business a year ago, but left one big mystery behind: the rollable phone it teased at CES 2021. Now a video on YouTube may have revealed a working version of the device in the wild.

The LG Rollable, as we assumed it would be called, first appeared in the company's CES press conference, which showed the phone's display smoothly extend -- but so smoothly that it could've been CG magic. The LG Rollable in the YouTube video surfacing today looks real, though, and the screen even looks responsive to touch commands. Other factors in the video like reflections make it even more likely that this is the real deal, as The Verge pointed out. 

It's tough to tell how functional this version of the LG Rollable is, meaning it could be a prototype with only a working display or a market-ready version. The short video does show us that the back of the LG Rollable has three cameras and a flash, though neither are used, nor do we see any software but the home screen. Given LG intended to release the Rollable in 2021, this could be closer to the final version of the phone. 

LG didn't respond to request for comment by time of publication.  

About 13,000 pounds of Home Run Inn frozen meat pizzas are being recalled due to potential metal contamination. The product's meat topping "may be contaminated with extraneous materials, specifically metal," according to a Sunday announcement from the US Department of Agriculture's Food Safety and Inspection Service.

The recall applies to 33.5-ounce boxes of Home Run Inn Chicago's Premium Pizzeria Deluxe Sausage Classic Pizza with a best by date of Dec. 3, 2022. That's the equivalent of about 6,256 pizzas.

The issue was discovered when customers sent complaints stating that metal was found in the pizza. No confirmed reports of injuries or adverse reactions due to eating the product have been made, the USDA said.

If you recognize this product in your freezer, check to see if the label, expiration date and other specific information matches that of the recalled product.

Home Run Inn's pizzas aren't the only products that have been recently recalled. Many drinks made by Lyons Magnus, including products from Oatly, Premier Protein and Stumptown, have also been pulled due to possible contamination.

The Xiaomi 12 Pro -- the latest flagship from the Chinese brand -- is stuffed full of top tech, including the newest Snapdragon 8 Gen 1 processor and a 120-watt wired fast charger that claims a blisteringly fast recharge speed. Combined with a top-end camera, the 12 Pro offers strong competition to the likes of the iPhone 13 Pro, Google Pixel 6 Pro and Samsung Galaxy S22 Ultra, even if it's a relatively unknown brand in the US. Having spent some time with the phone, there's a lot I like about it, from its glorious screen and its wildly powerful processor to its solid camera.

The phone will go on sale later this month in the UK and Europe, and while US availability is yet to be confirmed, Xiaomi's official pricing puts the phone as starting at $999 for the base model (with 8GB RAM and 128GB storage), or roughly £765 and AU$1,380 when converted. I've been testing the higher model, with 12GB RAM and a more generous 256GB of storage, although how much more that'll set you back isn't clear at the time of writing. 

That price puts it squarely on par with the base iPhone 13 Pro, while sitting $200 under the S22 Ultra, making it a potentially solid option for those of you wanting a high-performance Android phone while still keeping some cash left in your bank account. 

Humdrum design, beautiful display

Physically I don't think the phone is particularly exciting to look at, at least in the gray color that my review model arrived in. It's perfectly fine and if you usually use a case then it's probably a moot point, but its plain frosted glass back and standard rectangle camera unit are a little uninspired. I'd at least opt for the purple or blue colors it's also available in to add a bit of aesthetic appeal. 

Still, it feels sturdy to hold, and it uses toughened Gorilla Glass Victus on the front and back so I'm confident it can take a few knocks without shattering into a million pieces. It doesn't have an official IP waterproof rating (that I've been told so far, at least) so it's worth keeping it especially safe when holding it near swimming pools, toilets or clumsy friends carrying beers. I've asked Xiaomi for clarification on waterproofing as this is a common feature on flagship phones and I'd hope to see this here. 

On the front is a 6.73-inch AMOLED display which is both bright and vibrant. Its punchy colors will suit those of you who play a lot of colorful mobile games, while its 3,200x1,440-pixel resolution means that even tiny details are pin sharp. It has a 120Hz refresh rate too, making scrolling seem buttery smooth, but you can turn this down (or leave it on auto) in order to preserve battery life. 

Solid camera

On the back you'll find three 50-megapixel cameras: a standard zoom, a 2x telephoto zoom and an ultrawide camera. The main camera uses a 1/1.28-inch sensor which is physically larger than you'll find on the iPhone 13 Pro. Larger sensors typically mean they can capture more light and therefore produce better looking shots. 

So far in my testing I've found the 12 Pro's images to be generally decent, but not outstanding. Colors are vibrant and exposure is fine, although the ultrawide lens sometimes overexposes some highlights in a scene. 

The 2x zoom lens is good, but I'd like to have seen a longer zoom range -- 5x or even up to the Galaxy S22 Ultra's amazing 10x optical zoom. A longer zoom really opens up more interesting compositions that are still out of reach with a 2x lens. 

That large main image sensor helps it take fairly bright, sharp images at night and I'd say that my test shots so far are pretty much on par with Android rivals such as the Pixel 6 Pro or the Oppo Find X5 Pro. It can shoot video at up to 8K resolution and you'll find dedicated video effects, along with optical stabilization for smoother-looking handheld footage.

Huge power

Inside the phone is Qualcomm's latest 5G-enabled Snapdragon 8 Gen 1 processor, backed up by a meaty 12GB of RAM on my review model. It's an absolute powerhouse, achieving benchmark scores that comfortably outpace the Galaxy S22 Ultra, Pixel 6 Pro and Oppo Find X5 Pro. 

While it's important to remember that benchmarks are by no means a complete indicator of performance, the phone does feel extremely capable in everyday use. Navigating around the Android 12-based interface is swift and lag-free while playing demanding games like Asphalt 9: Legends and PUBG. It all looks incredibly smooth, with high frame rates at all times. 

Good battery and fast charging

Inside the phone is a 4,600-mAh battery, which gets comfortably through a full day of mixed use. How much you tax your battery will always depend on your behavior, but if you're checking email throughout the day, listening to podcasts and other general tasks, you'll likely even have enough power to spare for the next day. Heavier use like spending the day filming 8K video and playing graphically intensive games will likely drain the battery fast enough to warrant charging in the afternoon.

But the phone's incredibly speedy 120-watt fast charging is estimated by Xiaomi to fully recharge the phone from empty in around 18 minutes, hopefully making that afternoon boost pretty easy if you need it. I haven't yet been able to test that claim as it requires a specific faster charger, which normally will come in the box but did not arrive with my review unit.

Cheaper, smaller Xiaomi 12 

The 12 Pro is joined by the smaller Xiaomi 12. Beneath its 6.2-inch display is the same Snapdragon 8 Gen 1 processor, so you can expect similar blistering performance. The rear cameras have been pared down however, with a 50-megapixel main sensor, a 13-megapixel ultra wide and a 5-megapixel 2x telephoto. 

It'll come with a more affordable starting price of $749 and could be a good option if you want a high-performance phone in a smaller package.
