Why The Fastest Memory Isn't In Your PC (SPONSORED)

Mon, 13 Jul 2026 19:25:00 +0000

Thanks to Micron for sponsoring this video! To learn more about High-Bandwidth Memory (HBM), check out: https://www.micron.com/products/memory/hbm

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.

Why PC Memory is Stuck in 1995 (Unified Memory Explained)

Thu, 09 Jul 2026 20:12:00 +0000

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!

Why End-to-End Encryption Isn’t Enough

Fri, 26 Jun 2026 18:40:00 +0000

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.

Why Turning It Off And On Actually Works

Fri, 19 Jun 2026 19:22:00 +0000

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.

DLSS 5 (and the Backlash) Explained

Fri, 12 Jun 2026 19:26:00 +0000

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.

Three People Control what’s on Your Keyboard

Fri, 05 Jun 2026 20:15:00 +0000

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.

What Is Docker - and why it’s EVERYWHERE

Tue, 26 May 2026 19:37:00 +0000

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.

Why Gaming on Linux Suddenly Matters

Thu, 14 May 2026 19:00:00 +0000

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.

What Is Sideloading And Is It Going Away?

Thu, 23 Apr 2026 19:26:00 +0000

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.

Why You Shouldn't Trust Your Smart Ring

Wed, 08 Apr 2026 18:38:00 +0000

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 requires some massive engineering compromises. In this episode, we break down why your smart ring might be "fat-fingering" your biometric data.

A huge thank you to Dr. Daniel Franklin and the Franklin Research Group at the University of Toronto’s Institute of Biomedical Engineering for their expertise. Check out their incredible work on wearables and biomedical engineering here: https://franklinresearch.ca/
