The internet has become a vital tool for human connection, but it comes with its fair share of risks, with the biggest being your privacy and security. With the big tech giants hungry for every ounce of your data they can get and scammers looking to target you every day, you do need to take a few precautions to protect your online privacy and security. There’s no foolproof approach to these two things, and unfortunately, the onus is on you to take care of your data.

Before you start looking for a VPN or ways to delete your online accounts, you should take a moment to understand your privacy and security needs. Once you do, it’ll be a lot easier to take a few proactive steps to safeguard your privacy and security on the internet. Sadly, there’s no “set it and forget it” solution for this, but I’m here to walk you through some useful hacks that can apply to whatever risks you might be facing.

Don’t use real information, unless you have to

When you install an app on your phone, you’ll often be bombarded with pop-ups asking for permission to access your contacts, location, notifications, microphone, camera, and many other things. Some are necessary, while most are not. The formula I use is to deny every permission unless it’s absolutely necessary to the app’s core function. Similarly, when you’re creating a profile anywhere online, you should avoid giving out any personal information unless it’s absolutely necessary.

You don’t have to use your legal name, real date of birth, or an email address with your real name on most apps you sign up for. Some sites also still use antiquated password recovery methods such as security questions that ask for your mother’s maiden name. Even in these fields, you don’t have to reveal the truth. Every bit of information that you put on the internet can potentially be exposed in a breach. It’s best to use information that’s either totally or partially fake to safeguard your privacy.

If your personal information is easily available on Google, and you want to get it removed, you can send Google a request to remove it. Check Google’s support page for how to remove results to see specific instructions for your case. For most people, the simplest way to remove results about yourself is to go to Google’s Results About You page, sign in, and follow the instructions on screen.

Use email aliases to identify where your data was leaked from

Most modern email services let you create unlimited aliases, which means that you don’t need to reveal your primary email address each time you sign up for a new service. Instead of signing up with realemail@gmail.com, you can use something like realemail+sitename@gmail.com. Gmail lets you create unlimited aliases using this method, and you can use that to identify who leaked your data. If you suddenly start getting a barrage of spam to a particular alias, you’ll know which site sold your data.

Your photos reveal a lot about you

When you take a photo, the file for it contains a lot of information about you. By default, all cameras will store EXIF (exchangeable image format) data, which logs when the photo was taken, which camera was used, and photo settings. You should remove exif data from photos before posting them on the internet. If you’re using a smartphone to take photos, it’ll also log the location of each image, which can be used to track you. While social media sites may sometimes remove location and exif data from your pictures, you cannot always rely on these platforms to protect your privacy for you.

You should take a few steps to strip exif data before uploading images. The easiest way to get started is to disable location access for your phone’s camera app. On both iPhone and Android, you can open the Settings app, navigate to privacy settings or permissions, and deny location access to Camera. This will mean that you won’t be able to search for a location in your photos app and identify all photos taken there, and you’ll also lose out on some fun automated slideshows that Apple and Google create. However, it also means that your privacy is protected. You can also use apps to quickly hide faces and anonymize metadata from photos.

While you’re at it, don’t forget that screenshots can also leak sensitive information about you. Some types of malware steal sensitive information from screenshots, so be sure to periodically delete those, too.

Think about what you use AI for

Nearly every single AI tool is mining your data to improve its services. Sometimes, this means it’s using everything you type or upload. At other times, it could be using things you’ve written, photos or videos you’ve posted, or any other media you’ve ever uploaded to the internet, to train its AI models. There’s not much you can do about mass data scraping off the internet, but you can and should be careful with your usage of AI tools. You can sometimes stop AI tools from perpetually using your data, but relying on these companies to honor those settings toggles is like relying on Meta to keep your data private. It’s best to avoid revealing any personal information to any AI service, regardless of how strong a connection you feel with it. Just assume that anything you send to an AI service can, and probably will, be used to train AI models or even be sold to advertising companies.

You can delete information stored with data brokers

Yes, big companies like Facebook or TikTok can track you even if you don’t have an account with them. Data brokers collect vast troves of information about your internet visits, and sell it to advertisers or literally anyone who’s willing to pay. To limit the damage, you can start by following Lifehacker’s guide to blocking companies from tracking you online. Next, you can go ahead and opt out of data collection by data brokers. If that’s not enough, you can also use services that remove your personal information from data broker sites.

A VPN isn’t always the right answer

Now, I’m sure some of you are thinking that using a VPN will protect you from most of the tracking on the internet. That may be true in some cases, but using a VPN 24/7 is not the right approach for most people. For starters, it just routes all your traffic via the VPN company’s servers, which means that you need to place your trust in the company’s promises not to log your information, and its ability to keep your data safe and private. It also won’t protect you from the types of data leaks that might happen from, say, publicly posting photos tagged with location data.

Many VPN providers claim to be able to protect you, but there are downsides to consider. Some companies such as Mullvad and Proton VPN have earned a solid reputation for privacy, but using a VPN all the time can create more problems than it solves. Your internet speed slows down a lot, streaming services may not work properly, and lots of sites may not load at all because they block VPN IP addresses. In most cases, you’ll probably be better off if you use adblockers and an encrypted DNS instead.

Try a different combination of privacy tools

For most people, ad blockers are a good privacy tool. Even though Google is cracking down on ad blockers, there are ways to get around those restrictions. I highly recommend using uBlock Origin, which also has a mobile version now. Once you’ve settled on a good ad blocker, you should consider also using a good DNS service to filter out trackers, malware, and phishing sites on a network level.

Having a DNS service is like having a privacy filter for all your internet traffic, whether it’s on your phone, laptop, or even your router. I’ve been using NextDNS for a few years, but you can also try AdGuard DNS or ControlD. All of these services have a generous free tier, but you can optionally pay a small annual fee for more features.

Use a good firewall for your computer

Almost all apps these days send telemetry data to remote servers. This isn’t too much of a problem if you only use apps from trusted sources, and can help with things like automatic software updates. But malicious apps or even poorly managed ones may be more open with your data than you would like.

You can restrict some of that by using a good firewall app. This lets you monitor incoming and outgoing internet traffic from your device, and restrict devices from sending unwanted data to the internet. Blocking these requests can hamper some useful features, like those automatic app updates, but they can also stop apps from unnecessarily sending data to online servers. There are some great firewall apps for Mac and for Windows, and you should definitely consider using these for better online privacy.

Switch to a good password manager

I’ve probably said this a million times, but I will repeat my advice: use a good password manager. You may think it’s a bit annoying, but this single step is the easiest way to greatly improve your security on the internet. Password managers can take the hassle of remembering passwords away from you, and they’ll also generate unique passwords that are hard to crack. Both Bitwarden and Apple Passwords (which ships with your Mac, iPhone, and iPad) are free to use, and excellent at their job. Go right ahead and start using them today. I guarantee that you won’t regret it.

A study this week has found that shoppers using Instacart are often charged different prices for identical products at the same store at the same time, even when selecting in-store pickup rather than delivery. The Groundwork Collaborative, a progressive policy group, and Consumer Reports organized nearly 200 volunteers across four cities to simultaneously check prices on 20 grocery items. Price differences appeared on nearly three-quarters of the items tested. In one test, more than 40 participants selected the same Safeway in Washington, D.C. and the same brand of eggs. Prices ranged from $3.99 to $4.79 — a 20% spread. At a Target in North Canton, Ohio, Skippy peanut butter was $2.99 for some shoppers and $3.59 for others. The full 20-item basket varied by about 7% within each store.

An Instacart spokeswoman said retailers on its platform set their own prices and that some run short-term, randomized pricing tests. The company said tests were “never based on personal or behavioral characteristics.” Instacart acquired Eversight, an AI-driven pricing optimization company, in 2022. A Target spokesman said the company is not affiliated with Instacart and bears no responsibility for prices on the platform. Safeway and parent company Albertson’s declined to comment.

Apple’s Studio Display hasn’t been updated since it launched in 2022, but it remains one of the best monitors for the Mac-oriented, and right now you can pick one up for $230 off. This deal applies specifically to the tilt-adjustable model, which means you can’t adjust the height of the built-in stand. That might be a deal-breaker for some users, but if not, $1,368 is a near-record low.

The Studio Display was a product that Apple devotees had been asking the company to make for years. As well as being a solid 27-inch 5K LED monitor, it also packs in a variety of ports and some surprisingly good speakers. In our 80-scoring review at the time, we praised its bright and color-accurate screen, while bemoaning the fact that it isn’t as smooth as Apple’s many ProMotion-equipped devices.

If you’re content with what’s already on offer, this is a good deal on what has always been a very expensive luxury device, but bear in mind that there are swirling rumors of a next generation Studio Display that could arrive in 2026. Mark Gurman of Bloomberg reported earlier this year that Apple might currently have two new models in the works, though it isn’t clear if both will end up making it to retail.

Rep. Haley Stevens (D-Mich.) filed articles of impeachment against Health Secretary Robert F. Kennedy Jr. Wednesday, accusing him of abusing the powers of his office and undermining public health, putting Americans’ lives at risk.

He “has got to go,” Stevens said in a video announcing the impeachment articles. In an accompanying press statement, she said Kennedy, who rose to prominence as an ardent anti-vaccine activist, “has turned his back on science, on public health, and on the American people—spreading conspiracies and lies, driving up costs, and putting lives at risk.”  She called him the “biggest self-created threat to our health and safety.”

It is very unlikely that an impeachment push will gain traction in the Republican-controlled Congress. No other Democratic lawmakers are backing the articles.

It’s Christmas time, so I’m taking a look at myths related to the holiday. Last week, I focused on myths about Jesus. This week I’m taking a look at that other beloved Christmas icon: Santa Claus, the central figure in the secular holiday mascot pantheon, who is so mysterious, we can’t even agree on his real name. 

I’m sure he’s innocent of any crimes, but Santa has many aliases. Among many other sobriquets and honorifics, the guy who brings presents in December goes by Jolly Old St. Nicholas, Kris Kringle, Père Noël, and Father Christmas. That’s a lot of fake identities, but what is his real name? And who invented him? 

Did Coca-Cola invent Santa Claus?

There is an often repeated myths that the modern image of Santa Claus—red clothes, white beard, fat—was created by the Coca Cola company in the 1930s to sell soda. But nah. While it’s true that Coke blanketed popular publications with ads featuring Haddon Sundblom’s illustrations of a red-clad hefty boy drinking Coke, Sundblom’s was drawing on existing depictions of Santa, particularly the 1822 poem “A Visit From St. Nicholas,” commonly called “‘Twas the Night Before Christmas.”

Did Clement Clark Moore invent Santa Claus? 

“A Visit from St. Nicholas” was written by Clement Clark Moore’s and the poem did create some Santa details that have been nearly universally adopted. The chubbiness, the twinkly eyes, the jollyness, and the rosy cheeks are pure Moore. Also the sleigh and reindeer, the reindeer’s names, and Santa coming down the chimney were invented by Moore. But Moore didn’t invent Santa, because Moore thought St. Nick was a wee baby man. 

Santa Claus is not a wee baby man

While Twas the Night Before Christmas offers no specific height for St. Nicholas, Moore describes St. Nick as “an elf,” and “a little old driver,” who pilots a “miniature sleigh” towed by “eight tiny reindeer.” He is said to fit up the chimney with ease, even though he has a belly like a bowlful of jelly. The preponderance of clues from Moore’s poem suggest St. Nick is around two feet tall.

Moore’s poem isn’t even about Santa Claus. It’s about St. Nick, and much of Moore’s inspiration was based on centuries-old traditions, and those were based on folk myths drawn from Catholic hagiographies. But if you trace Santa Claus mythologies all the way back to the year 300, during the Roman Empire, you will actually land on a historically verified person who lived on earth. So Santa Claus is real—kind of.

Jolly Old St. Nicholas: original Christmas badass

Above is a depiction of St. Nicholas painted between 1503 and 1508. You may be wondering why St. Nick is pictured gesturing to three miniature, naked men standing in a wooden barrel—like what kind of Christmas parties did they have back then?? I’m going to get to it, believe me, but first—the facts.

Saint Nicholas of Myra, also known as Nicholas the Wonderworker, was a Catholic bishop who lived in Turkey during the Roman Empire and (probably) attended the First Council of Nicaea in 325. He died on Dec. 6 sometime around 343. That’s all we know for sure about St. Nick—the earliest accounts of his life and deeds were hagiographies written centuries after his death, so, according to leading St. Nick historian Jona Lendering and common sense, can’t be relied upon. But still, a cult formed around St. Nick, people built churches to him, and we still talk about him today as a good guy who brings kids presents, so he must have done something right. Here are only some of the good deeds and miracles attributed to St. Nicholas:

• As an infant, refused to suckle his mother’s breast on Fridays

• Rescued three girls from prostitution by giving their father gold to pay their dowries

• Calmed a storm at sea

• Saved three soldiers from wrongful execution

• Remained chaste

• Chopped down a tree possessed by a demon

• Slapped the heretic Arius at the Council of Nicaea for suggesting God created Jesus

All those are good deeds, but one tale of St. Nick is a great deed that stands head and shoulders above the others; St. Nicholas, it is said, resurrected three children who had been murdered, chopped up, and and pickled in brine by an evil butcher planning to sell them as pork during a famine. 

As you’d probably expect, the story of St. Nicholas confronting an evil butcher and bringing pickled children back from the grave caught on with people in a bigger way than the one about him slapping a heretic. Some variations had him enslaving the evil butcher and bringing him around on his yearly rounds to beat naughty children with a stick.

All of which brings us back to the homunculi:

They’re wearing goose suits.

The story of the resurrected children so enthralled people that artists started depicting St. Nick with three little buff boys in a vat (they only look like old men because painters in the early medieval period sucked at drawing children). “St. Nick with naked children” was seen so much that even people who hadn’t heard the story of the butcher associated the saint with children and he became known as the Saint who liked children (but not in a gross way). The legend and cult of St. Nicholas spread far and wide, and when it made it to the Netherlands, they called him “Sinterklaas” which eventually became Santa Claus.

The religious rivalry of Kris Kringle and St. Nicholas

Kris Kringle and St. Nick were once bitter enemies, products of warring religious dogmas, but Christmas magic and American religious tolerance melded them into a single holiday entity.

By the 17th century, a jolly old saint named Nicholas bringing children presents on Dec. 6 was the tradition all over Europe. But Protestant reformer Martin Luther did not want no Catholic saint giving presents to no Protestant kids. So Luther replaced St. Nick with Jesus himself, creating and popularizing a tradition where Baby J gives children presents on Dec. 25, the anniversary of the day He was born, rather than St. Nick giving them presents on Dec. 6, the anniversary of his own death.

The gift giver was called Christkindl, the Christ Child and was often depicted with wings. Said to hide mischievously when delivering gifts, Christkindl was to grown-up Jesus as The Muppet Babies are to The Muppets—not quite canonical, but fun for kids. He was also St. Nick’s enemy, sent to erase the jolly old saint from the Protestant imagination, and the operation was partially successful. Christkindl is still the default seasonal gift bringer in some parts of the world. But the joke was ultimately on Martin Luther.

Christkindl came to the U.S. with German immigrants in the 1800s. Germans met the Dutch settlers who were already here and devoted to St. Nicholas. Presumably because both St. Nicholas and Christkindle are myths told to children, there was no bitter, bloody religious war. Not a single heretic was slapped. Instead, they compromised: America gradually settled on presents being delivered on Dec. 25 instead of Dec. 6, but Santa Claus brought the gifts instead of Christkindl, whose name eventually morphed into “Kris Kringle,” another name for Santa/St. Nick.

Nvidia has developed location verification technology that could determine which country its AI chips are operating in, Reuters reports, citing a source, a capability that may help address ongoing concerns about the smuggling of advanced semiconductors to restricted markets like China. The feature, which Nvidia has demonstrated privately in recent months but has not released, would be an optional software tool that customers install. It taps into the confidential computing capabilities of Nvidia’s GPUs and uses the time delay in communicating with Nvidia-run servers to approximate a chip’s location.

The technology will first be available on Nvidia’s newest Blackwell chips, though the company is examining options for its older Hopper and Ampere generations. U.S. lawmakers and the White House have pushed for location verification measures as the Department of Justice has brought criminal cases against smuggling rings allegedly attempting to move more than $160 million worth of Nvidia chips to China.

Dr. Mehmet Oz, the administrator for the Centers for Medicare and Medicaid Services (CMS) and former daytime talk show star, has recently been emailing all federal workers in his agency weekly tips on “Crushing Cubicle Cravings” and how to avoid snacking in the office.

“We all love a fun cookie swap and potluck this time of year. With several teams across CMS hosting holiday gatherings this month, I am sharing some strategies to help you make healthier choices—while still indulging in festive treats,” Oz wrote in his latest missive, which appears as a recurring section in his weekly bulletin titled “From the Administrator’s Desk,” according to emails viewed by WIRED.

“Set your intentions,” writes Oz. “Decide in advance how many treats you’ll allow yourself to enjoy and try to stick to that number. You don’t have to try every cookie on the cookie table.”

Not long ago, you may have thought of projectors as complicated, unreliable or just too expensive. In 2025, though, consumer sentiment started to flip. Companies like Anker and Valerion made the projector experience more practical and immersive, helping drive consumer interest and, ultimately, sales.

This shift has been quite a few years in the making. LG helped kickstart the projector renaissance back at CES 2018 when it introduced its unusual-looking CineBeam HU80K projector that could provide a 150-inch image. The next year at CES saw the dawn of the ultra short-throw (UST) laser projector that could create a similarly large display while sitting just inches from your wall. Another big technological upgrade over the following years was the bright and long-lasting laser light engines that replaced weaker, more fragile bulbs.

The timing couldn’t have been better for projector manufacturers. When COVID shut down theaters in 2020, consumers were forced to get their entertainment at home. Many wanted something akin to a movie theater experience — both indoors and out — and thus interest in projectors started to take off.

In 2025, though, projectors really entered the zeitgeist thanks to two new products. The first was Anker’s SoundCore Nebula X1, the highest-rated home theater product Engadget reviewed this year. It comes with a triple-laser engine that allows for 3,500 lumens of brightness — enough that you can watch it during the day. It also uses liquid cooling to reduce annoying fan noise and offers color-accurate picture quality with support for Dolby Vision HDR.

Even better, it can be carried outside easily via the retractable handle and used for movie nights under the stars. If you splurge for the Soundcore Nebula X1 Pro version that comes with huge party speakers, you can even expect excellent sound quality. It also looks sleek and modern, unlike the plasticky models normally aimed at mid-range buyers.

However, the most interesting feature — which is new for a projector in this price range — is the motorized tilting lens that automatically fits the picture to your screen or surface. That allows buyers to set up the Nebula X1 themselves in just a few minutes, rather than hours. That also makes it easy to move the projector around and use in another location.

Valerion

The other model that captured our imagination was the Valerion VisionMaster Max. This projector shares many traits of the Nebula X1, like Dolby Vision, a triple laser system and automatic setup. It’s also a nice-looking, modern product.

However, it has two other innovations that made it extra interesting. The first is the dynamic iris and its Enhanced Black Level technology. That had reviewers raving about its deep black levels that were comparable to projectors like JVC’s NZ8 that cost twice as much. The other is the so-called anti-rainbow technology, which eliminates most of the rainbow-hued strobing that appears with models using Texas Instruments DLP chips. This resolves a common complaint with mid-range projectors.

For a similar price as a good quality TV ($1,500 – $3,000), these models can beam an image double the size. And to install one, you just need to position the projector in front of the screen, roughly center it and hit “calibrate” to get a perfect image.

Both the X1 and VisionMaster Max were first announced on Kickstarter and became the top two projectors ever sold on the site. Plus, several projector models, particularly from Anker/Soundcore, appeared on Google’s gadget search trends. All of that is helping the home projector market increase to the point that it’s, well, projected to nearly double by 2030.

As people researched these products, they may have noticed the other advantages. Along with movies, they’re also great for gaming and sports, particularly if you have a big group of people. In fact, they actually take up less room than a TV if both the projector and screen are ceiling mounted. And many models are portable, battery-powered and bright enough to use outside for parties and camping.

Steve Dent for Engadget

A prime example of a recent projector convert is Engadget editor and cinema podcaster Devindra Hardawar, who explained why he decided to make the leap. “I know big TVs have gotten cheaper, but they still can’t reach the massive 120-inch screen size of my Formovie ultra-short throw projector,” he said. “It makes watching anything feel truly cinematic, and not like I’m just staring at another screen.”

Even though projectors are gaining some ground, they won’t replace TVs for most people. Mid-range televisions still cost less at around $1,000. TVs are obviously easier to install and more convenient to use, as all projectors need time to warm up. TVs are much brighter, too: even dim models put out at least 500 nits of brightness, compared to 200 to 300 nits max for very bright projectors. However, even though projector setups are less tricky than before, you still need to buy and install a screen for optimal performance, which adds cost and complexity.

How much more can projectors improve? I think they’ll continue to get brighter, more color accurate and even easier to install. Another piece of technology with potential to reduce complexity and improve image quality is the roll-up screen. If those come down in price enough, they may convince some buyers to replace their TVs with a projector. They’re still likely to remain a niche product, but for cinephiles who want a theater-like experience, projectors are now a more compelling option.
