Jeff Geerling

Intel just matched Apple Silicon. Seriously.

Jeff Geerling tests the $699 Dell XPS 13 ($599 for students and teachers) and argues it would not exist if Apple had not shipped the MacBook Neo in March: Dell copied the idea and did most of it one notch better, with a matte 120 Hz variable refresh touchscreen at higher resolution, a backlit keyboard on par with Apple's, two 10 gigabit USB ports that both drive displays instead of Apple's single 480 megabit USB 2 port, and a 512 GB SSD that doubles the Neo's base storage, runs faster, and can be swapped by the owner. The losses are real: weaker speakers, no headphone jack at all, audible fans, Windows as the only officially supported OS complete with an Xbox ad and a OneDrive nag, and a Core i5 iGPU that cannot hold a candle to the Neo's A19, with the almost entirely GPU bound Gravity Mark showing the Mac nearly doubling the Dell's score. The surprise is efficiency. On the Top 500 supercomputing benchmark the chip throttles after ten seconds to settle at 20 watts and still crushes every other x86 chip Jeff has ever tested for compute efficiency, and when he re-ran the suite on the four e-cores alone and then on the performance cores alone, each set separately landed among the most efficient computers he has measured, beating most Apple Silicon Macs. Idle draw matches Apple at under a watt with the display off and about 4 watts at half brightness, and Wi-Fi 7 sustains a gigabit for a few watts. He pops out Dell's drive, installs Fedora 44, gets every piece of hardware working after a USB Ethernet adapter and a round of updates, and recommends the machine at the price largely because Linux will keep it alive long after both Dell and Apple stop caring.

you need to use Hermes RIGHT NOW!! (goodbye OpenClaw!!)

NetworkChuck makes the case for switching from the OpenClaw agent harness to Hermes, the agent from Nous Research, and walks through installing it on a Hostinger cloud VPS wired to ChatGPT Codex and Telegram. He builds a Hogwarts themed IT agent named Ron Weasley, then shows the five reasons he switched: the vibe, the memory system with hard caps that force curation, the people and story behind the tool, agents that write their own skills via a self improvement loop, and the fact that it just does not break. Live demos have the agent learn the network over Twingate, control a Home Assistant studio, and manage UniFi, crystallizing its own skills as it goes. Cofounder Jeffrey Quesnelle joins to explain the philosophy: give the model hands and get out of its way.

Install Kasm Workspaces in 10 Minutes (Docker + Remote Desktops in Your Browser)

Sonoran Tech makes the case for disposable computing and then builds it: Kasm Workspaces runs containerized apps and full Linux desktops on a server in your home lab and streams them into a browser tab, so the link you do not trust and the bank session both run somewhere that is not your machine and neither one survives being closed. He demos a Chrome workspace and a whole Ubuntu desktop in a tab, then builds a fresh Proxmox VM (Ubuntu Server, eight cores, modest disk), pastes the single server install block straight off the Kasm docs, catches live that the install script needs sudo, and is emphatic that you write down the credentials the installer prints because recovering them means going into the database. The last third is the part quick starts skip: persistent profiles, which take one host directory at /mnt/kasm_profiles owned 1000:1000 with mode 700, a profile path configured per workspace rather than globally, and path variables that segment the data by user and image. He proves it by touching a file in an Ubuntu session, deleting the session outright, and finding the file waiting in the next one. The hard limit he states plainly: profiles persist your home directory, not apt installs, so the moment you need package changes to stick you are back on a full VM or building a custom workspace image.

Kubernetes Course – Certified Kubernetes Administrator Exam Preparation (2026 Update)

A full Certified Kubernetes Administrator (CKA) prep course aligned with Kubernetes 1.34 and the 2026 exam environment. It walks the entire official curriculum in order, building a real multi node cluster with kubeadm and demonstrating every task hands on: cluster architecture, installation, upgrades, etcd backup and restore, RBAC, deployments and rolling updates, autoscaling, services and ingress, network policies, persistent storage, and systematic troubleshooting. Every concept comes with the kubectl commands and YAML manifests, mapped to the exam domain weights where troubleshooting is the heaviest. You could study for the CKA from this course alone.

Complete Kasm Deployment Guide - Proxmox, Cloud & More

Jay LaCroix of Learn Linux TV deploys Kasm Workspaces, the self hostable platform that streams apps and full Linux desktops into a browser tab, four different ways. He builds it in a Proxmox VM (the same recipe as bare metal), hand builds it on an Akamai cloud instance, hardens that instance with a real Let's Encrypt certificate, and finishes with a one click DigitalOcean marketplace droplet. The installer is identical everywhere: download the Linux Server tarball, extract, run sudo bash install.sh, and log in as admin@kasm.local. Along the way he covers the standard new server hygiene (non root user, sudo, hostname, updates, reboot) and the certificate swap that turns the self signed warning into a trusted green padlock.

Kasm Workspaces Simplified: The Essential Guide for New Users

Jay LaCroix of Learn Linux TV gives a complete getting started guide for Kasm Workspaces, the container based platform that streams individual apps and full Linux distributions into a web browser tab. He covers what Kasm is and its use cases, the server requirements and supported distributions, the standard installer, and a full tour of the admin console. Then he launches and manages workspaces (Alma Linux, Doom, Firefox), closes sessions, wires up the Open in Isolation browser plugin, adds a third party linuxserver.io registry, removes workspaces, and breaks down the self hosted and cloud pricing tiers. A hands on companion to his separate Kasm review, aimed at anyone ready to self host it.

Kubernetes Crash Course for Absolute Beginners [NEW]

Nana Janashia teaches all of Kubernetes in one hour. It starts with what container orchestration is and why microservices made it necessary, walks the cluster architecture of master and worker nodes, then explains every component you use day to day (pods, services, ingress, ConfigMaps, secrets, volumes, deployments, and StatefulSets) by building one example app. The second half is hands on: install Minikube and kubectl, write four YAML files, and deploy a MongoDB database with a Node.js web app reachable in a browser through a NodePort service. A reader finishes able to stand up a real application on Kubernetes.
