WhatsApp has added the ability to make secure phone calls directly through your web browser, using the same strong encryption that protects your phone calls. If you spend time at your computer and want to talk to friends or family without switching devices, this makes conversations more convenient while keeping them private. Worth knowing: you'll need to have WhatsApp open on both your computer and phone to make web calls work properly.
Hundreds of private conversations that people had with Claude, an artificial intelligence chatbot, were accidentally left visible to the public on the internet. If you've been using Claude to discuss personal matters, ask questions about your health, or work through sensitive topics, there's a small chance your conversation could have been seen by strangers. Worth knowing: Anthropic (the company behind Claude) has now fixed the problem, but if you've used this chatbot, it's sensible to avoid sharing anything you wouldn't want others to read.
A Canadian man spent 18 months in prison because police searched for a username with one underscore when they should have searched for one with two underscores—a tiny typo that sent them after the wrong person entirely. Small mistakes in digital investigations can have enormous real-world consequences, especially when someone's identity is at stake and the system doesn't catch the error early. Worth knowing: if you or a family member ever finds yourself questioned by police about online activity, it's worth asking them to triple-check the exact usernames and account details they're investigating, since even tiny differences can make all the difference.
# Claude's Public Chat Sharing Has a Privacy Catch
Anthropic's Claude AI tool has a sharing feature that lets you create links to conversations, but those links can accidentally become visible to Google's search engine, potentially exposing private chats to anyone who searches the right terms. If you've shared Claude conversations or projects with colleagues or friends, there's a chance those shared links ended up searchable online without your knowledge. Worth knowing: if you use Claude's share feature, check your sharing settings carefully and consider whether the conversations contain anything you'd prefer to keep private.
Apple has just released new versions of its software for iPhones, iPads, and computers that patch up security weaknesses hackers could exploit. These updates are especially important because they protect your personal information—like passwords, photos, and financial details—from being stolen or misused. Worth knowing: it's a good idea to install these updates as soon as your device prompts you, usually by going to Settings on iPhone or System Settings on Mac.
USB 3.0 transfers data about ten times faster than USB 2.0, even though the ports can look nearly identical to the naked eye. If you regularly back up photos, videos, or large files to external drives, the faster speed means you'll spend less time waiting around—sometimes the difference between a five-minute and fifty-minute backup. Worth knowing: most modern computers have USB 3.0 ports (often marked with a blue plastic insert inside), so check your device's manual or look for that blue indicator before buying new cables or external drives.
# iPhone SOS Mode Fix
Your iPhone sometimes gets stuck displaying "SOS" because it lost proper cellular connection, which can happen after updates or when switching networks. If this happens to you, it's annoying because you can only make emergency calls, so you'll want to fix it quickly to use your phone normally again. Worth knowing: the simplest solution is to turn your phone completely off, wait a few seconds, then turn it back on—and if that doesn't work, toggling airplane mode on and off often resets the connection.
# How to Clear The Cache On Your Roku TV
Your Roku TV stores temporary files (called cache) that help it run smoothly, but sometimes these files get cluttered and cause slowdowns or freezing. Clearing this cache is like giving your TV a quick refresh—it can fix annoying glitches without losing any of your settings or passwords. Worth knowing: you can usually do this by going to Settings > System > Power, then holding the reset button on your remote for a few seconds until you see a confirmation message.

You can visit Samsung's Galaxy Watch Designer website right now and experiment with different colors, layouts, and information displays, then download your creation directly to your watch.
Australia tested its national emergency warning system last week, sending a loud alert to most phones, smartwatches, and tablets around the country—though some people never received it at all. The government considers the test successful because it helps them understand which devices and locations have coverage gaps, which matters if a real emergency like a bushfire or flood needs immediate public warning. Worth knowing: if you didn't get the alert, your phone's emergency settings might need checking, and you can test this by going into your phone's settings to ensure emergency warnings are turned on.
Artificial intelligence is being used to create fake doctor accounts on TikTok that spread false health information to millions of people, and medical experts are warning this is genuinely dangerous. When someone in their 50s, 60s, or 70s sees what looks like a trusted doctor recommending a "miracle cure" online, it's easy to be fooled—especially if you're dealing with a health concern that worries you. Worth knowing: if you see health advice on social media from someone you don't recognize, check with your real doctor first, and be skeptical of any claims about miracle cures or quick fixes.
Apple is working on smart glasses that could show information right in front of your eyes, but the company needs to figure out how to keep your privacy safe while you're wearing them. Because these glasses would have cameras and sensors constantly near your face, people worry about whether they'll accidentally record conversations or collect personal information without permission. Worth knowing: when any new wearable device comes out, check what data it collects and whether you can turn off the camera or microphone when you're not using those features.
