Over the years I've tested sh1t loads of different Linux distros... for anyone out there that wants to get started with Linux there are a few distros I ALWAYS recommend... this is one of them!! Latest video on YouTube - link in bio 😀

So UGREEN sent me their new NAS, the DXP6800 Ultra. Instead of the standard review video Ive built it for 4 different users.. The Standard NAS User, The Smart Home User, The Media Center User and the Local AI User. You can see the entire walkthrough on YouTube - Link in Bio.

The CCNA changes on Feb 3rd 2027.. it will include an AI section and the return of troubleshooting questions. 😩🤮 If your planning to sit the CCNA before Feb 3rd - YOU SHOULD! Then I made a video covering the changes and what I would do to pass before it changes! 🎥 link in bio

The days of spending hours building services are over! You need to use Proxmox container templates, virtual machine templates and community scripts!! This is gonna save you hours of time! Check it out 🎥 Link in Bio

Hey everyone, I finally got around to play with Arcane... honestly one of the best docker managers I've used! I made a video where I build it from scratch and walk through the platform! Check it out - Link in Bio

I accumulated too many devices over the years..old laptops gathering dust, then I realized..what if I built one server and accessed everything from anywhere? Thats when I built "THE BEAST" using KASM Workspaces. Now I can log in from any device, any location. Link in bio 😆

Proxmox released its Data Center manager platform a while ago... in this video I'll walk through the platform.. lets check it out and see if its worth using! 🎥 Full Video on YouTube - Link in Bio

RIGHT It's time I got my act together! I've completely lost track of all my home servers so I've built Uptime Kuma and I've set up Telegram notifications! When my server sh1ts itself...I get a message! 😀. Full video on YouTube - Link in bio

Every major Linux gaming distro joined forces this year. But CachyOS said no... but then it became one of the most popular gaming distros on the planet 👀 I've been using Bazzite.. but I had to try CachyOS! The GOAT of Linux gaming? 👉 linktw.in/maFGxr

ONE MILLION VIEWS! 😳 A few days ago, my Tech with Gerard YouTube channel reached a milestone! 1,000.000 views which is actually INSANE! Genuinely, thanks to everyone who's watched and subscribed!! If you want to join in, you'll find me here: tech.gerard.ws 😊

Started with Googling myself (we've all done it 😅)..fell down an OSINT rabbit hole..spun up Kali and found a bunch of OSINT tools.. I discovered the real problem: my browser fingerprint. So I built an untraceable OSINT lab that I can burn down in seconds. linktw.in/XSCIPJ

You need a homelab ! Seriously you do! The final episode of the Proxmox cluster series is on YouTube! This final part covers the most important part too, adding Backup storage location, backups, replication and HA! The we put it to the test! 🎥 Watch here: linktw.in/HoDRoi

Episode 2 of the Proxmox series is up. Got storage and networking sorted on both nodes — ZFS on NVMe, VLAN aware bridges and a private internal network. 🎥 Watch it here: linktw.in/UWjwnr #Proxmox #Homelab #ZFS #TechWithGerard

This week I took my two ZimaBoard 2s and a Raspberry Pi and built an entire Proxmox Cluster! This is part 1 of a 3 episode Proxmox series where I'm walking through the entire build. 🎥 Watch here: linktw.in/wWXoqc #Proxmox #Homelab #TechWithGerard

Claude Desktop on Linux isn't officially supported. So I got it working anyway. 🐧 Full walkthrough 👉 linktw.in/rOlhdq #Linux #Claude #AI

Has anyone seen the ZimaBoard 2? If you're looking for something you can use to self-host some apps, containers, virtual machinbes etc then seriously.. you need to see this video. linktw.in/XjrRSX #HomeLab#ZimaBoard#SelfHosted

Want a free ethical hacking lab to study for PenTest+? I made a new video for you: Build the Ultimate Ethical Hacking Lab in 30 mins • Kali Linux install • VirtualBox setup • Metasploitable 2 & 3 build 🔗 linktw.in/UwHwcD #EthicalHacking #CyberSecurity #PenTest #Kali

Be honest!! 👇 Are you managing Linux servers in the terminal… or would you actually use a web GUI like Cockpit? CLI forever? 😎 Or browser-based management? Let’s go!! linktw.in/LZrwfZ #Linux #ServerManagement #Cockpit #WebGUI #Terminal #SysAdmin #DevOps #OpenSource

I built my own password manager. Self-hosted. Docker. Vaultwarden. Because I’d rather control my passwords than rent security from someone else. Cloud convenience is great… But control hits different. Full build video 👇 linktw.in/fiteZN

Is the love for Windows really coming to an end? I tested 5 Linux distros people are switching to as they move away from Windows — installs, UI, and ease of use. If you’re even thinking about leaving Windows, this will save you a lot of time. linktw.in/QTcciH
