Cursor's Memory Bank

I am Cursor, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.

Memory Bank Structure

The Memory Bank consists of required core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:

Linux high IOwait is a common Linux performance issue. Today we will look at what iowait means and what contributes to this problem. Hope this can give you more ideas about high IOwait issue.

What is IOwait?

IO wait is related to the CPU resource on the server.

The iowait column on top command output shows the percentage of time that the processor was waiting for I/O to complete. It indicates that the system is waiting on disk or network IO. Because the system is waiting on those resources, it can not fully utilize the CPU.

Learn more about what IOwait here.

Ubuntu Server Setup - with netplan

Introduction

The assumption here is that you're now starting with a Ubuntu 22.04 LTS Server or newer, rather than Desktop, base (Ubuntu Desktop deploys NetworkManager rather than systemd-networkd by default). This box has an AMD Ryzen CPU.

The goal is networking configured for static addressing using systemd-networkd and netplan. Note that punctuation (including hypens, '-') and indentation are significant when working with netplan YAML files.

There are a lot good arguments against using netplan. I have tried NetworkManager (packages named "network-manager", but the service is "NetworkManager.service" -- go figure) on Ubuntu Server, and was

How to install Java JDK8 in Ubuntu 16.04

Let's consider a JDK8 installation using 2 different versions: default and Oracle. The default version is easiest because it is packaged with Ubuntu.

There is default Java installation called the JDK (Java Development Kit). The JDK is usually only needed if you are going to to do some software developmwent using Java or if some software requires it. The JDK does contain the JRE.

Installing the default JDK

# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything

# Increase history size
export HISTSIZE=5000

# In the command below - every time a new prompt is issued (ie whenever you get through running a command), first the history is appended to the file, then it is cleared from the current shell's memory, then the current shell reloads the history from the file. 
#export PROMPT_COMMAND="history -a; history -c; history -r; ${PROMPT_COMMAND}"

It is easy to export bash commands to syslog which can be centralized and analyzed.

Add the following lines to bashrc.
