Ram's Technology Notes
I recently built a new home server (post about this later) and as part of this reboot decided to setup proxmox and utilize containers for improving security and isolation for different services hosted in my home server. Everything has worked quite well (another post about this later) but because I wanted to keep my old…
Here are some useful commands for managing a Proxmox server and containers:
I am setting up a new home server and before I install final headless software, I am doing burn in tests where I am using a desktop install (Kubuntu specifically). I wanted to set up remote access for the desktop. Played with different VNC servers and clients and experienced terrible latency issues on a multi-gigabit…
One of the great leaps in recent years with virtualization is PCI Express device passthrough from host to guests – this essentially allows near native access and performance of PCIe devices in VMs and leads to experiences that feel like you are running two physical computers inside one. Since this technology has evolved and matured…
This is a brief introduction to setting up and running Virtual Machines in Linux. While there are several different options to accomplish this, my preferred method is using KVM + QEMU + LibVirt. Here’s what each of these does: QEMU is a full-fledged stand-alone emulator that can emulate all kinds of hardware for virtual machines…
Finally got an NVidia 3060 and a new machine that I built now that prices for GPUs are more reasonable. I am running Manjaro on this new machine and one of the reasons for putting it together was to continue working on the FastAI book. Now the recommended approach by the authors is to use…
This was way more annoying than it should have been – I am using imwheel to increase scroll speed and wanted to set up my Manjaro 5.15 KDE environment so that it starts automatically at startup. The following things did not work: Setting up an autostart shortcut to imwheel Setting up a login script for…

You should in general prefer to install from the official Manjaro or AUR repos whenever possible. But in the rare case (cough Microsoft Edge cough) where this is not possible, here are a sequence of steps you can follow to install a .deb package in Manjaro (and other Arch based distros) You need to install…
This is the set of steps you need to take to enable complex touchpad gestures in Manjaro (KDE, but should work for other desktop environments as well). By default, single and double finger gestures should work and are configurable in the default touchpad configuration settings. However, three finger and other gestures are not available by…
