Who among us has not looked at a newly framed picture, then looked at their wall and thought, "Eh, surely I can eye-ball it this time." Hanging pictures should be an easy feat, but so often they end up uncentered or slightly crooked, causing us to add more holes the wall than intended or desired. The next time you hang pictures or artwork in your home, use one of these 10 hacks so they're level and evenly spaced on the first try.

Use a small ball as a makeshift level to hang pictures

A level is essential when hanging art—a frame that’s even slightly crooked will be an eyesore, and if you’re hanging multiple pieces in a group, it’s even more important that everything be level. If you forgot to grab your level, or you don’t have one, you can use a small ball, like a ping pong ball or a marble. Place it on top of the frame and adjust until the ball sits still, then mark it on the wall.

Use painter’s tape to accurately space two nails when hanging a picture

If your frame has two widely spaced hooks, knowing where to insert your nail, screw, or other fastener on the wall can be a mind-bending challenge. But if you have some painter’s tape on hand, it’s easy: Place a piece of tape across the back of the frame, with the top of the tape lined up with the top of the hooks. Mark the position of the hooks with a marker or pen, then remove the tape and place it on the wall at the desired height. Using a level, adjust the tape until it’s placed correctly. Then drive your nails right through the tape at the marked locations, remove the tape, and hang your picture. Here's a visual tutorial.

Use toothpaste to help you mark the spots where hooks or nails need to go

An alternative to the painter’s tape method is to use some toothpaste (or any gooey, sticky stuff that will wash off your wall easily). Mark the hooks on the back of the frame with a gob of toothpaste, check that it's level and at the desired height on your wall, then press the frame against the wall. The toothpaste will mark the precise spot where you need to drive your nails to hang the frame. Insert your fasteners, clean everything up, and hang that picture in the perfect spot. Here's a visual tutorial.

Make this quick DIY tool to mark the spot for a hook or nail when hanging a picture

If you have spare cardboard (a cereal box will do) and a pin or thumbtack, you can make a little DIY tool that will make marking the spot for a hook or nail easy. Cut out a rectangle of cardboard, then cut a tab at the bottom that’s narrow enough to fit through the hook on the back of the frame. Slide the tab through, and push a pin or tack through from the back. Then push the picture into the wall at the right spot, and the pin will create a tiny hole where your hook or nail needs to be. Here's a visual tutorial.

Use string to guide a hook onto a nail when hanging a picture

Got the nail in the wall, but can’t seem to catch the hook on the picture frame? Get a piece of string and loop it around the nail, then adjust so the ends are even. Take both ends together and run them through the hook, then pull the string tight as you bring the frame toward the wall. The string will guide the hook right onto the nail, no guesswork required. Here's a visual tutorial.

Use a fork to guide wire onto a nail when hanging a picture

If your frame uses a wire across the back to catch a nail or hook in the wall, you know that sometimes you question your own perception of reality as you repeatedly fail to catch the hook on the wire. There’s an easy hack: Grab a fork from the kitchen and place it on the nail or hook in the wall so it leans outward. Then hook the wire onto the stem of the fork and slide the frame down, letting the fork guide the wire down. When it’s hooked, remove the fork and admire your work. (And wash the fork, probably.) Here's a visual tutorial.

Hang pictures with Monkey Hooks if you don't want to use any tools

Hanging art on drywall and dread all the mess and trouble of drilling or nailing? Skip it by using Monkey Hooks instead. These are self-drilling pieces of wire—you just poke them through the wall with a tiny bit of elbow grease—that spin around and provide strong, secure hooks that can hold up to 50 pounds of weight, all without a single tool. Here's a visual tutorial.

Make this paper template when you're hanging multiple pictures in one area

If you’re going to be hanging multiple frames on the wall, grab some paper and create a template first. You can use wrapping paper, butcher paper or any kind of paper you have lying around or can get your hands on cheap (you can also use cardboard if that’s what you have on hand). Lay your frames out on the paper and trace them carefully. Then use the toothpaste or cardboard/nail hacks described above to mark where the nails need to be placed. Hang the template on the wall (ensuring it’s level), hammer in your nails, remove the template, and hang your frames. Here's a visual tutorial.

Use an envelope to catch dust when drilling to hang a picture

If you’re going to drill or nail into your walls to hang pictures, you’re going to get a lot of annoying dust all over the place, unless you use a very simple hack: Tape an envelope to the wall underneath where you’ll be drilling. It will catch all that dust and save you the extra step of vacuuming afterward. If you don’t have any envelopes (or tape), some Post-it Notes will do in a pinch—just fold one in half and stick it to the wall under the spot where you’ll be drilling, and it will catch that dust. You can combine more than one Post-it if you need to. Here's a visual tutorial.

Use your own saliva to mark the spot where you need to hang a picture

If all else fails, and you need to hang a framed picture but you are short on time or patience, there’s a simple solution: Lick the back of your finger, curl it over the hanging hook on the back of the frame, and place it against the wall at the desired height (typically around 57-60 inches from the floor). Your own saliva will leave a faint, temporary mark on the wall where you can confidently place your hook without fuss or delay.

The Sony HT-Z9F is down to $419.99 on Woot, a steep drop from its original price of $899.99. At this price, it becomes a far more accessible way to upgrade your TV audio without committing to a full AV receiver and multi-speaker setup. The deal is available for the next 16 days or until it sells out, whichever happens first. Prime members receive free standard shipping, while non-Prime customers pay $6. That said, shipping is not available to Alaska, Hawaii, APO addresses, or PO Boxes, and the purchase includes a 90-day Woot limited warranty.

It’s a 3.1-channel soundbar, meaning it has left, right, and center speakers built in, plus a wireless subwoofer. That dedicated center channel is especially helpful for dialogue—it keeps voices clear and easy to follow, even during action scenes or loud background scores (meaning you do not need to ride the volume during conversations, then scramble to lower it when explosions hit). And then, there’s the wireless sub, which adds weight to action movies and bass-heavy playlists. It is not room-shaking, but it gives enough low-end punch to feel cinematic in a living room setting.

Sony markets the HT-Z9F as Dolby Atmos-enabled, but it does not have upward-firing drivers or rear satellite speakers. Instead, it relies on Sony’s S-Force Pro Front Surround and Vertical Surround Engine to simulate height and surround effects. That processing does create a wider sound field than basic stereo, but everything still feels anchored to the front of the room. Overhead effects lack the distinct placement you would get from true Atmos speakers bouncing sound off the ceiling. If you are upgrading from built-in TV speakers, the improvement will be obvious. But if you expect a fully immersive surround with objects flying above and behind you, this will not deliver that experience.

As for its connectivity, you get two full HDMI inputs that handle all major audio formats, plus HDMI ARC for TV connection. You also get Bluetooth, wifi, and built-in Chromecast for streaming music directly from your phone or apps. The design looks premium and feels sturdy, which helps it blend into a midrange or high-end setup. The tradeoff is limited sound customization. There are preset EQ modes, but no detailed treble or bass adjustments. At $419.99, the HT-Z9F makes sense for someone who values clear dialogue and solid bass, with wide-format support. Those chasing a true Atmos surround setup with discrete height channels may want to look elsewhere.

Samsung has officially revealed when its next Galaxy Unpacked event, which is where everyone's expecting the Galaxy S26 series to be announced, will take place. But before it airs on Feb. 25 at 1 p.m. EST, the company's offering the chance to get ahead of the game by trading in your current phone for a little extra moolah. Right now, you can sign up on Samsung's website to trade in your phone for up to $900 while pre-ordering a Galaxy S26 phone (or, on the very unlikely chance the S26 isn't announced at the event, whatever is announced in its place).

How to get $900 on Samsung Galaxy S26 trade-in

That's $200 more than Samsung currently offers on trade-ins for its other phones, which top out at $700 when trading in a Galaxy S24 Ultra for a Galaxy S25 phone. And while you're signing up, you'll also get $30 to spend on accessories during (but not before or after) your pre-order. You can also choose to be entered in a $5,000 sweepstakes for general Samsung online store credit, if you'd like.

The catch? The pre-order window doesn't seem to be open quiet yet. Usually, that happens within a week of Galaxy Unpacked airing, but you can still get the process started now. Just head to Samsung's Galaxy Unpacked reservation website, enter your name and at least an email address (you can also toss in your phone number, if you'd like), and you'll be taken to the form you need. If you want to enter the sweepstakes, also check the box saying you want to enter.

From there, you can pick your current phone manufacturer and your phone model from a drop-down menu. Note that the manufacturer options include Samsung, Apple, Google, and "Other," so it seems like Samsung is willing to let you trade in phones it doesn't make, too. As for the model picker, you can pick models going back around five years for each of the manufacturer options, although if you don't see your model on the list, you can also pick "Other" here, too.

How much will Samsung give me for my phone?

I can't promise how much Samsung will give you for each specific phone model, although it stands to reason that newer and higher spec phones will earn you more. I'm also willing to wager that Samsung might give you more credit if you trade in one of its own phones, but that's just speculation. To get the full $900, I'm guessing you'll need to trade in a Galaxy S25 Ultra.

Once you've made your selection, hit Submit, then scroll down a bit and click what you're interested in getting offers from Samsung on. Make sure you at least select "Trade In," and then click Submit here, too.

And that's it for now. Samsung will now know what type of phone you have and that you're interested in a trade-in, and should email you with an appropriate trade-in offer once it's available. Again, this should happen closer to Unpacked, likely within a week of Feb 25.

What will the Galaxy S26 look like?

All in all, it's a good opportunity for a deal, but it does continue an unfortunate trend of Samsung's—asking you to pre-order a device before it's officially been revealed, and before you know its full specs list. Luckily, a number of rumors for the Galaxy S26 has made it easy to guess at what we're likely to see, including a similar look to the S25, no ultra thin S26 Edge model, a Snapdragon 8 Elite processor, and a new 10MP telephoto lens on the Ultra model. For confirmation, though, we have no choice but to wait.

If you're a PC gamer who's been looking into getting a Steam Deck to help you play your games on the go, then I've got some bad news for you: On Valve's official Steam Deck store page—the only place to buy new Steam Decks in the United States—every single model is sold out right now. That includes the discontinued LCD model, both versions of the Steam Deck OLED, and even refurbished options.

The shortage was first spotted last night by deals hunter Wario64, who at the time noted that the Steam Deck was sold out in the U.S., but still available in other countries. Unfortunately, since then, both Tom's Hardware and Windows Central have reported that the handheld isn't available in some Asian countries either. There does still seems to be some hope for gamers in Europe, as Windows Central's Adam Hales said he could still see available stock in his native U.K., including the discontinued Steam Deck LCD.

Valve has yet to comment on the sudden disappearance of the Steam Deck from its site, although I've reached out and will update this post if I hear back.

Why is the Steam Deck out of stock?

While Valve hasn't provided an official reason for the Steam Deck shortage, an obvious culprit is the ongoing RAM crisis, which has seen the cost for consumer memory components double or even triple as AI data centers eat up the available supply. It's possible this shortage is finally affecting the Steam Deck, although that's just speculation until Valve officially confirms it.

That said, the explanation would align with a post Valve made to its blog last week, in which the company said its upcoming Steam Machine and Steam Frame hardware are being impacted by "memory and storage shortages." While the company didn't outright announce a delay for these devices, saying it still plans to ship them "in the first half of the year," it also noted "we must revisit our exact shipping schedule and pricing."

It's possible the situation with "limited availability and growing prices of these critical components," as Valve put it it that post, is now affecting the Steam Deck too, though there are other possible explanations. The simplest, and most hopeful, is that this is simply a minor hiccup in availability, and it will be corrected by the end of the week. Alternatively, it's possible the shortage could be related to tariffs, as while whole smartphones and computers are exempt from increased tariffs, it's unclear whether that applies to gaming devices, or to any individual components Valve might purchase to construct new Steam Decks.

At any rate, we can't know for sure until we hear back from the Half-Life company itself. Perhaps slim pickings or higher prices are in the Steam Deck's future, but there's no way to know right now.

What to buy instead during the Steam Deck shortage

While we don't yet know how long the Steam Deck will stay sold out, it might be worth looking into getting a different handheld gaming PC if the situation drags on. While you can buy Steam Decks from unofficial sellers, I wouldn't advise it, as these would all be from the secondhand market. Most come with heavily marked up prices, and it's impossible to know what kind of condition your device will be in when it arrives. A more trustworthy alternative could be GameStop, as the retailer does sell its own certified refurbished Steam Decks, which are cleaned up in a separate process from Valve's. Unfortunately, these are also out of stock at the moment.

Instead, I would suggest looking at alternatives like the Lenovo Legion Go S, which starts at $600, is slightly more powerful than the Steam Deck, has a higher resolution screen, and in an official partnership with Valve, comes equipped with the same operating system as the Steam Deck. (I actually prefer the Legion Go S to the Steam Deck myself.)

If you've got cash to burn, you could look at a premium upgrade. The obvious ones here are the Lenovo Legion Go 2, which ups the power and packs a gorgeous OLED screen; and the Asus ROG Xbox Ally X, which may be more welcoming to console gamers. (That said, the Xbox handheld's software wasn't quite there yet, at least when I reviewed it).

Whatever your choice, you have no shortage of options for PC gaming handhelds to keep you occupied while you wait for the Steam Deck to come back in stock. Gamers will always find a way to play.

It's once again time to update your Apple devices. The company just released a whole host of security patches, including a fix for an actively exploited zero-day affecting iOS 26, iPadOS 26, and macOS Tahoe. These updates arrived alongside the official release of iOS 26.3, which includes features like more seamless data transfer between iPhone and Android. Other security patches address bugs in Photos, VoiceOver, and Screenshots, to name a few.

iOS 26.3 patches a zero-day affecting dyld

According to Apple's latest security bulletin, the zero-day—tracked as CVE-2026-20700—is a memory corruption issue in dyld, Apple's "Dynamic Link Editor." The flaw could allow attackers with memory write capability to execute arbitrary code—or, in other words, run their own code on your device.

Apple says that the vulnerability may have been exploited in an "extremely sophisticated attack against specific targeted individuals" in earlier versions of iOS alongside CVE-2025-14174 and CVE-2025-43529. Those at greatest risk with this bug are likely high-profile users with access to sensitive data—users who might be inclined to use Apple's Lockdown Mode—but everyone should install the update to patch the issue.

The patch for this flaw is available for the following iOS and iPadOS devices, in addition to all Macs that run macOS Tahoe:

  • iPhone 11 and later

  • iPad Pro 12.9-inch 3rd generation and later

  • iPad Pro 11-inch 1st generation and later

  • iPad Air 3rd generation and later

  • iPad 8th generation and later

  • iPad mini 5th generation and later

How to install the latest security update for iPhone

You should have automatic updates enabled to ensure you receive critical security patches ASAP, but you can confirm that you're on the latest OS version under Settings > General > Software Update. As a reminder, Apple won't message you urging you to click links, download attachments, or install apps related to security updates. Always go through your device settings to receive official fixes.

If you're an Apple fan who closely follows tech news, you might have been looking forward to Siri's big AI overhaul for some time now—specifically, since the company initially announced it at WWDC 2024. But despite delay after delay, rumors have strongly suggested that the next generation of Siri is set to launch with iOS 26.4. And seeing as Apple just released iOS 26.3 this week, AI Siri is closer than ever, right? Wrong.

As reported by Bloomberg's Mark Gurman, Apple has once again kicked Siri's big updates down the road. According to Gurman, the company really did intend to release AI Siri with iOS 26.4, which is reportedly planned to release sometime in March. However, due to testing "snags," the company is instead planning to break up Siri's major updates and distribute them across several iOS updates. Gurman notes that likely means iOS 26.5, which could launch in May, and iOS 27, which will likely release in September, if it follows Apple's usual release dates. But looking at Apple's track record here, don't hold your breath.

AI Siri's upcoming features are a struggle

According to Gurman's sources, Apple is struggling to get Siri to "properly process queries," or to actually respond fast enough, both of which would defeat the purpose of using a smart assistant. Apple is reportedly pushing engineers to use iOS 26.5 to test these features, particularly the ability for Siri to use your personal data to answer questions. Users may be able to flip a switch in Settings to "preview" these features, and may treat the rollout as a beta.

Engineers are also struggling to get Siri's app intents to work, or the feature that lets Siri take actions on your behalf. You could ask Siri to open an image, edit it, then share it with a friend, but only if the feature itself actually works. This, too, may roll out with iOS 26.5, but it's unclear due to reliability issues. Siri is also cutting off user prompts too soon, and sometimes taps into ChatGPT instead of using Apple's underlying tech—which would look pretty bad for the company.

Apple is also testing new AI features for iOS 26.5 that we haven't heard of yet. One is a new web search tool that functions like other AI search features from companies like Perplexity and Google. You ask a question to search on the web, and it returns a report with summaries and links. The other new feature is a custom image generation tool, that builds on Image Playground, but that too is hitting development hurdles.

Looking even further ahead, Apple is planning more Siri advancements—namely, giving the assistant chatbot features, à la ChatGPT. (That said, it will reportedly use Gemini to power these features.) This version of Siri may even have its own app.

What's going on with AI Siri?

It seems Siri really is Apple's albatross. Despite arguably popularizing smart assistants for the general population, Siri quickly fell behind compared to the likes of Alexa and Gemini (née Google Assistant). Now, the latter have fully embraced modern generative AI, offering features like contextual awareness and natural language commands. While Amazon and Google users can ask their assistants increasingly complicated questions, Siri still feels designed mostly to handle setting alarms and checking the weather.

That was going to change with iOS 18, alongside Apple Intelligence as a whole. Apple's initial pitch for AI Siri was an assistant that could see what's on your phone to better understand questions you ask, and take actions on your behalf—i.e., app intents. You could ask Siri to edit an image you have pulled up on your Photos app, and because the assistant is contextually aware, it would know what image you mean, and apply the edits you ask for. Or, you could ask when your friend was set to arrive, and the assistant would be able to scan messages and emails to know that, one, your friend is visiting town this weekend, and two, that they sent you their flight itinerary that gets them into the airport at 3:55 p.m.

This Siri has never launched, however. While the company has rolled out iterative updates to Siri with some AI-powered features, its overhaul with these ambitious features have been a trial for Apple's AI team. It all stems from Apple's issues with AI in general: The company was caught off guard by the generative AI wave kicked off in late 2022 by OpenAI's ChatGPT, and following some resistance from corporate leadership, have been scrambling to keep up ever since. Apple Intelligence launched half-baked with issues of its own, but rather than launch a half-baked AI Siri, the company has been struggling to build up the assistant internally.

Part of the problem is privacy-related: Unlike other tech companies, who have no problem hoovering up user data to train their models with, Apple still wants to preserve privacy while rolling out AI features. As such, that complicates their situation, as they need to ensure both the hardware and software involved meet those standards. You can't have Siri pull user data into the cloud without strict security measures if you want to ensure your users' data remains private. The company is also focused on building its own hardware for cloud-based AI processing, rather than focus on simply buying up GPUs as many other companies have.

Apple is the second most valuable tech company in the world, but a host of factors—including with software, hardware, and leadership—have made it so even Apple can't magically produce an AI assistant. Though, I'm not sold that an AI Siri will move units for Apple in the first place. I can't imagine Gemini moves people to Android, and you can download ChatGPT on any device you own. It's even now built into your iPhone.
