The rm -rf / command is one of the most dangerous things you can type on a Unix system - Riley explains what it does, why it exists, and how to protect yourself from accidentally nuking your computer.

USB has been around for decades, yet it’s never been more confusing. We break down USB data speeds, connector types, and modern standards to help you finally understand what your cables can really do.

There's been a lot of talk about data centres in the news lately so we wanted to make a video to help people understand the various types and the distinctions between them.

Why is buying a phone charger so confusing? USB-C was supposed to simplify everything - but the watt numbers, the branding, the cables, and the ports have somehow made it worse. We break down the 5 reasons you're probably getting it wrong, and what to actually look for next time you buy.

From the Samsung Galaxy Ring to the Oura and the rumored Apple Ring, everyone wants to "put a ring on it." But shrinking a laboratory's worth of sensors into a titanium hoop requir es some massive engineering compromises. In this episode, we break down why your smart ring might be "fat-fingering" your biometric data.

Downloading apps seems straight forward, but on mobile it's anything but. There are hoops to jump through, pop-ups to fend off, and monolithic app stores to contend with. Getting full control on Android is even slipping further and further away. Join us as we embark on a journey to get to the bottom of sideloading.

Wi-Fi 7 has some awesome features, at least theoretically. However, MLO one of the most impressive features is still not widely available, let's try and find out why.

Remember when OLED was simple? You paid a premium, you got perfect blacks, and you called it a day. Fast forward to 2026, and we’re drowning in an alphabet soup of WOLED, QD-OLED, and "Penta-Tandem" stacks. Today we’re breaking it all down and we’ve got the answers. Special thanks to Ron Mertens, CEO of Metalgrass and founder of OLED-info, for joining us and sharing over 20 years of expertise in the display industry.

From broken drivers to the Steam Deck selling millions, Linux gaming has gone from "is this the year?" to "wait, it actually works now." But getting here took a decade of tinkering, a billion-dollar bet from Valve, and an open-source community that refused to quit. In this video we talk to Valve and the Batocera project about how Linux quietly became a real threat to Windows - and why Microsoft is playing catch-up.

In this video, we are breaking down why Docker is the ultimate upgrade for your homelab. We’ll look at how containers work, why they are so much faster and lighter than Virtual Machines (VMs), and how Linux under-the-hood wizardry makes it all possible.

Your phone is the best tool in your pocket for most things, but if you're privacy-minded, it might be working against you. This video explains how phone tracking works, and what you can do to try and control it.

The Unicode Consortium isn’t elected, isn’t a company, and you’ve probably never heard of them. But they decide which characters exist on every keyboard on Earth, including yours. We dig into how they got that power, why eight corporations pay fifty thousand dollars a year for voting rights, and how new characters get created.

DLSS 5 is here, and it's not what you think. Nvidia's calling it the biggest graphics leap since Ray Tracing, but the same audience that defended DLSS for eight years is calling this one AI slop. So what's actually going on? In this video, we break down what DLSS 5 actually does, how neural rendering works, why Nvidia's CEO and Nvidia's own engineers are describing the tech differently, and whether the backlash from gamers and developers is justified.

Why does turning your computer off and on again actually fix things? We explain what rebooting does to RAM, memory leaks, crashed services, and the weird little problems that build up while your PC is running.

Apps like Signal, WhatsApp, and iMessage promise nobody can read your messages. Mostly true - but in 2026, encrypted chat has three gaps you can't ignore, and the biggest one might already be sitting on your own computer. We sat down with David Wiseman, BlackBerry's VP of Secure Communications, to find out what end-to-end encryption actually protects, what it doesn't, and how attackers are walking around it without breaking a single line of code.

Computer memory is officially worth more than gold, thanks to AI. So why do our CPUs and GPUs still act like selfish jerks and refuse to share it? They can and it's called Unified Memory, and in this video we’re breaking down the physical bottlenecks of traditional PC architecture and explaining how Apple - and now AMD and NVIDIA - are rewriting the rules of hardware efficiency. Special thanks to Professor Prashant Nair from UBC for lending his engineering expertise!

Modern AI chips don't run on the kind of memory in your gaming PC. They run on something that's literally stacked into a tiny skyscraper, with tens of thousands of microscopic data tunnels drilled through it and a custom silicon motherboard underneath. We sat down with the engineers at Micron to break down how High Bandwidth Memory actually works, why it's the backbone of every serious AI accelerator on the planet, and why your gaming GPU still uses a totally different kind of memory.

Satellite internet used to be a last resort - laggy, expensive, and locked behind a hard data cap. Then low Earth orbit changed everything. We break down how it actually works, why it used to be so bad, what made it usable, and why physics means it'll never fully replace fiber - with astronomer and orbital tracker Jonathan McDowell.

Shopping is getting harder all the time. Virtual aisles filled with crap and fake reviews, but thankfully new tech is....er... making things worse... If you've been burned by things getting more expensive or changing price this video is for you.

Stop swiping your apps away! You might think you’re saving battery life or freeing up RAM when you force-close background apps, but you’re making your phone work harder. In this video, we break down why force closing is an exercise in futility, app states and what the overview screen really tells you, and the only exception when you should force-close an app. Special thanks to Niel Lebeck who does work at Google, but is joining us in a personal capacity to share insights from his PhD research on Android memory management (his views are his own and do not represent Google).

What are DLSS, FSR, XeSS, and PSSR? What do they actually do? In this video, we explain how modern upscaling technologies boost gaming performance, the differences between spatial, temporal, and machine learning based upscaling, and why these tools are changing the future of gaming graphics. Special thanks to Ubisoft’s Nicolas Lopez!

A homelab isn't a scary server rack humming in a basement - it's just a computer you own, quietly running the services you'd normally rent from the cloud. We break down what you can actually run on one, what hardware to run it on, and how to start without wrecking your power bill or getting hacked. Whether you want to kill your subscriptions, take back your data, or pick up real tech skills, this is where you start.

Not only is RAM getting more expensive, but it's also changing to open up the possibility of much faster speeds in a smaller form factor. We got to chat with the inventor of CAMM Tom Schnell who gave us the inside track on how it was developed.

For years, SteamOS only came on a handheld Valve blessed, while your gaming PC stayed stuck with Windows. Then Valve launched the Steam Machine - and quietly unlocked SteamOS 3.8 for any PC, completely free. We break down what actually makes SteamOS tick, walk through the gloriously janky install process (yes, you'll be editing Valve's own code), and find out whether it's finally good enough to ditch Windows - with Valve's own SteamOS engineers, Pierre-Loup Griffais and John Schoenick.

Your monitor might be showing you incorrect colors, but don't worry you can do something about that. In this video, we’re breaking down Delta E (ΔE) values: what they are, how they’re used, and how you can ensure you're getting the best color from your monitor.

How can you tell if something was made by AI? In this video, we explore the various methods used to flag AI-generated content, and how reliable they really are.

When you talk to AI it can feel like there's a real person talking back to you, but it's actually a computer program known as A Large Language Model. In this video, we break down how these models work at a very high level.

Valve's Steam Frame promises your entire Steam library on a standalone headset - but every one of those games was built for x86 processors, and the Frame runs an ARM chip straight out of a smartphone. The trick that makes it possible is FEX, a translator Valve has quietly funded for years that recompiles your games live, while you play. We break down how it works, what it costs in performance, and why it matters way beyond VR with Pierre-Loup Griffais, one of the Valve engineers behind SteamOS.

Intel’s lineup has undergone a ton of changes over the years, from replacing the i series naming scheme, to just recently dropping and restructuring a ton of suffixes. If you don’t know what that even means, you’re at the right place. Join us as we unpack the Intel Core & Core Ultra series chipsets as fast as possible. So you can be better informed next time you get bombarded by four chips that all have 7’s in them.

A quick introduction to foveation in VR, covering fixed and dynamic foveation, and foveated rendering and streaming.

If you were thinking about getting into the world of VR now that the Steam Frame has launched this video will unpack what all the buzzwords mean, and which ones you should care about.

You've installed Linux, so what's next. Time to install some apps!

Turns out that Wi-Fi 8 actually has some really awesome features that actually might make a differacne for home users, especially if you have a mesh network.

An overview of what a Googlebook laptop is, how it differs from existing laptops, and what it could mean for the future of personal computing.

The iPhone Duo is here and with it there's a chance that folding phones go more mainstream. If you're wondering how manufacturers managed to make folding glass a thing, this video is for you.

Phone batteries are getting larger again, but it's not just larger cells, it's a new chemistry process that's actually pretty interesting.

That suspicious 59.94 Hz refresh rate in your Windows settings isn't a bug - it's a relic of television history. Find out why engineers slowed down the original 60 Hz standard, how it affects modern video, and why this tiny change still matters decades later.
