Old Android phones and tablets make better security cameras than cheap IP cameras. You'll find a lot of apps designed for repurposing phones into live security cams. The apps generate a live stream that you can view inside a browser. However, you can also hook it up to a network video recorder to record or re-stream the feed from the Android device. That way it can seamlessly integrate into your existing security system.

I've had a computer in some shape or form for too long to mention now, and have been building my own PCs for 20 years. Those two decades span multiple desktops, including some that were technically the same PC that evolved multiple times over years of upgrades. I'm also the designated tech person for a number of my family members and friends, which means I'm often saddled with old PCs that they don't know what to do with anymore.

If your aging PC is struggling to keep up with the demands of a modern Windows version, you are not alone. It's pretty common for older hardware to be left behind as software evolves. However, that doesn't mean your system is ready for an e-waste dump.

Whenever I'm at the computer, I seem to have Spotify going in the background. With data on Spotify songs available, I wanted to see if any traits the hit songs had in common. I used Spotify to see if I could build a model of a hit song.

Before every weekend rolls around, I like to refresh my Netflix watch list with limited series and miniseries that I can typically wrap up within a day or two. And if you're like me, you know how exciting these shows can be for a perfect binge-watching session.

Unreliable Wi-Fi is the most frustrating and common issue we deal with. It's a real struggle when you have to deal with buffering screens, dropped video calls, issues with your smart home, and slow download speeds that usually make even new devices seem old. For years, the default advice for solving this problem has been to replace your old router. Performance does not depend on purchase price. If you master a few cheap software tweaks and small physical adjustments, you can get back significant speed and stability without spending money.

PowerShell is a Windows utility you can use to fix a surprisingly large number of common Windows 11 issues. It's often faster than digging through Windows 11 menus and in many cases, you can simply copy, paste, and execute commands without any further intervention on your side.

It's 2026, and Android still doesn't have some basic features like cutting off internet access for certain apps. Now there are third-party apps that make this sort of firewall possible on Android. However, they come with one big trade-off: they need to run constantly in the background as a VPN tunnel.

If you sideload books onto your Kindle, you'll know that things don't always go smoothly. Files sometimes don't even convert properly, the formatting can be completely unpredictable, and your library becomes messy very quickly. That's why I convert my eBooks in Calibre before putting them on my Kindle. It fixes almost all the problems.

So you've heard about Qubes OS, and you're scared to try it. Well, you should be. Qubes OS is not something you can fumble through; there's an upfront research cost, and just because you have a powerful computer, it doesn't mean it'll work. I explain the entire hardware landscape in simple terms.

Is your Netflix watch list looking a little dry? Netflix is set to release new titles in May as the heat picks up, which will ensure your summer watch list is packed with new, fresh films, shows, documentaries, and live events.

Running a Plex server starts out as a tidy experiment and then quietly turns into infrastructure. At first, it is a few movies in a folder, maybe a TV show or two that you swear you will organize later. Then one evening you open the library and realize half the metadata is wrong, some files refuse to match, and someone has just messaged you asking if you can “add that one show with the guy” (this description is somehow expected to be sufficient). That is the moment Plex stops being a media server and starts behaving like a system that needs tooling around it.

If you've already made the switch from VLOOKUP to XLOOKUP in Excel, you've taken the first step toward better formulas. But most people still only use it as a drop-in replacement—they're missing one of its most powerful capabilities.

Your 3D printer can turn photos and other images into physical objects using a variety of techniques. This includes—but is not limited to—lithophanes, a 19th-century technique that traditionally relied on porcelain but has since been updated for the modern age.

Sideloading is a hot topic in the mobile sphere, and Google recently made a huge change for how it works on Android. I think it’s a fantastic change, and I wish Google would have added the 24 hour delay for sideloading unverified apps years ago, but I’m glad they’ve finally done it.

Unlike its rival Apple, Samsung products run on various operating systems, such as Android, ChromeOS, Windows, and Tizen. While this is great if you prefer flexibility, it also means that users rarely get a consistent and cohesive experience across their devices.
