Oracle recently released it’s popular Enterprise Database for the Arm CPU. This is news, as it’s the first new architecture announced by Oracle since they added the Itanium architecture. In fact, this also reverses the current path, where Oracle has Continue reading Arming your Database! A comparison of Arm vs X64
Ever wonder how your ISP is really doing, with the quality of their services? Wouldn’t it be fun to be able to track critical metrics, like bandwidth availability and network latency? While we all think about how fast my internet Continue reading Monitoring Internet performance with a Raspberry PI #PiDay2023
I was talking with a friend recently, and he was looking for a quick and easy way to virtualize a small lab system. We discussed a full out hypervisor and management system like Oracle Linux Virtualization Manager (OLVM and Oracle’s Continue reading Installing KVM on ARM with Oracle Linux
I’m a huge fan of VNC. It’s a great way to get X access to a server, without having to install X on your PC. VNC aka Virtual Network Computer, also has an advantage that the X session is running Continue reading Setting up vnc server on Oracle Linux 8+ on ARM and X86

This post is a bit off the original plan, mainly due to timing. Short version on the timing, my Dell 7750 notebook (The one with a Xeon processor, 128G ram, and NVME storage…) had to get replaced. Dell was good Continue reading Storage Performance Part 3: UEK vs a standard kernel
In the previous post in this short series, I shared a benchmark between MicroSD card and a USB Drive. In this review we look at two different MicroSD cards, both with a U3 rating. The U3 rated card was Continue reading Raspberry PI Storage Performance: Part 2 U3 vs U3 Cards, they are all no equal
Recently I saw some discussion about storage performance on Raspberry PIs, with the focus being on performance between the MicroSD card vs. USB performance for the storage. This short series of BLOGs will compare several performance options for the Raspberry, Continue reading Raspberry PI Storage Performance: Part 1 USB vs SD Card
A question I get asked more and more, is how do you create a filesystem larger than 2TB on a linux server. Most admins know how to use fdisk, and then mkfs, but fdisk limits you to a 2T partition Continue reading How to create a Linux partition larger than 2TB
