# How To Convert Or Upscale A Photo
Modern tools can now enlarge your old photos and make them sharper and clearer, often with just a few clicks—no fancy software skills needed. If you have treasured photographs from years ago that are small or fuzzy, this technology means you can finally get them printed large or enjoy them in better detail on your screen. Worth knowing: several free online services (like Upscayl or Topaz Gigapixel) do this job well, so you might start by trying one on a photo you'd like to improve.
Amazon quietly started using Twitch streamers' videos to train its artificial intelligence without asking permission first, and people only found out when they noticed an "opt-out" option buried in the settings. For creators who've built audiences and spent years streaming, this means their hard work could be used to improve Amazon's AI tools without them getting paid or even knowing about it. Worth knowing: if you stream on Twitch or watch streamers regularly, you can check your privacy settings to opt out of this data collection, though it's frustrating that opting out should have been the default choice in the first place.
# How to Stop Twitch from Training AI on Your Streams
Twitch has started using content from streamers' broadcasts to train artificial intelligence systems, but you can turn this off in your account settings if you'd rather keep your videos private from that use. This matters because streamers spend hours creating content, and many feel that AI companies shouldn't profit from or copy their work without clear permission. Worth knowing: you'll need to go into your Twitch settings under "Content and Moderation" to find the opt-out option, and check back occasionally since streaming platforms sometimes change their policies.
# Meta Smart Glasses Privacy Concern
A German privacy organization has filed a criminal complaint against Meta because their new smart glasses can record video and audio of people without their knowledge or clear consent. For anyone concerned about privacy in public spaces, this raises real questions about whether companies should be allowed to build recording devices that are so discreet that bystanders don't even realize they're being filmed. Worth knowing: if you're in a public place and someone wearing Meta's smart glasses walks by, you might be captured on video without seeing any obvious camera or being asked permission.
Amazon has decided to use videos from Twitch streamers to train its artificial intelligence systems automatically, unless streamers actively say no to this practice. The company essentially admitted that if they asked permission first, almost no one would agree, which is why they're doing it the other way around. Worth knowing: if you or someone you know streams on Twitch, they should check their account settings to opt out of this AI training if they're uncomfortable with their content being used this way.
# HDMI Splitter vs. HDMI Switch
If you have multiple devices like a streaming box, Blu-ray player, and gaming console all plugged in, an HDMI switch lets you pick which one sends picture and sound to your TV, while a splitter does the opposite job—it takes one device and sends its picture to multiple TVs at once. A switch is usually what you need if your TV only has a couple of HDMI ports and you're tired of unplugging and replugging cables. Worth knowing: switches are affordable and simple to use, while splitters work best in specific situations like sending one movie to a TV in multiple rooms.
WiFi signals bouncing around your home or office can now create a kind of invisible picture of your body's movements, letting someone identify who you are without any camera or microphone. For those of us who value privacy, this matters because it means someone with the right equipment could potentially recognize you through a wall, using technology that's already in millions of homes. Worth knowing: if this technology becomes widespread, your WiFi router could theoretically reveal information about you without your knowledge—so it's worth understanding what devices are connected to your network and keeping your router's software updated.
Criminals are breaking into people's email and social media accounts to find and steal private intimate photos, which they then use to blackmail victims for money. This is happening to people of all ages, and it's particularly distressing because the photos are deeply personal and the threat of exposure causes real harm and fear. Worth knowing: if you use the same password across multiple accounts, change it now—criminals often hack one site and use those credentials to access others, so using unique passwords for email and important accounts makes you much harder to target.
Schools are increasingly sharing photos of students on their websites and social media, which is convenient for families but raises real concerns about how those images might be used by people with bad intentions. If you have grandchildren in school, it's worth understanding that these photos could potentially be collected and misused in ways that schools don't always anticipate or prevent. Worth knowing: ask your grandchild's school directly what their photo-sharing policy is, whether parents can opt out, and how they protect the images once they're online.
# Zoom Screen-Sharing Flaw
A security problem in Zoom allowed someone to take complete control of another person's computer during a video call, not just see their screen. For anyone who uses Zoom for video chats—whether with family, friends, or work—this meant a scammer or hacker could potentially access your files, passwords, and personal information without permission. Worth knowing: Zoom has fixed the problem, so make sure your app is updated to the latest version, and be cautious about sharing your screen with people you don't fully trust.
# MacBook and Multiple Monitors: What You Need to Know
Modern MacBooks can handle at least two external monitors at once, though the exact number depends on which model you own and how new it is. If you're thinking about expanding your workspace with extra screens for email, spreadsheets, or video calls—something many of us appreciate as we get older—a MacBook can make that happen without breaking a sweat. Before buying extra monitors, check Apple's website or ask a salesperson which specific MacBook model you have, since the newer ones (especially those with the latest chips) tend to support more screens than older versions.
Apple's iPhones have gotten better cameras, longer battery life, and faster processors over the past five years, but they still look and work much like earlier models so you won't feel lost picking one up. These improvements matter because a better camera means clearer photos of grandchildren, longer battery life means fewer midday charges, and speed means apps open instantly without frustration. Worth knowing: if you have an older iPhone that still works fine, there's no rush to upgrade—the changes are helpful rather than essential unless photography or battery life have been bothering you.
