set -e, -u, -o, -x pipefail

The set lines

These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euxo pipefail is short for:

set -e
set -u

Nx

https://nx.dev/

Nx is a suite of powerful, extensible dev tools to help you architect, test, and build at any scale — integrating seamlessly with modern technologies and libraries while providing a robust CLI, caching, dependency management, and more.

It has first-class support for many frontend and backend technologies, so its documentation comes in multiple flavours.

Principles

# Resize the file system in UI, under VM -> Hardware -> Click on the disk to resize, click "Resize disk" button

# Confirm increase in disk space (1TB in my case)
$ lsblk
NAME                      MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda                         8:0    0    1T  0 disk
├─sda1                      8:1    0    1M  0 part
├─sda2                      8:2    0    1G  0 part /boot
└─sda3                      8:3    0    1T  0 part

I could not reproduce the failure condition. I installed a 1-node cluster using this on Ubuntu 20.04 (Intel NUC).

INSTALLATION

This is from a user account with sudo privilege.

sudo snap install microk8s --classic --channel=1.19
sudo usermod -a -G microk8s $USER
sudo apparmor_parser -r /etc/apparmor.d/*snap-confine*

Populating Elasticsearch Index with Logstash

Logstash is a free and open server-side data processing pipeline that ingests data from a multitude of sources, transforms it, and then sends it to your favorite "stash."

This section describes how one can use it on UNIX to migrate data from a PostgreSQL database to elasticsearch.

The Prerequisites

Here are the steps needed to run a self hosted Open Street Map server (using Docker):

Download desired pbf files (like south-carolina-latest.osm.pbf) from https://download.geofabrik.de or just use the following empty planet below:


  <?xml version='1.0' encoding='UTF-8'?>
  <osm version="0.6" generator="osmconvert 0.8.8" timestamp="2019-10-23T20:18:02Z">
    <bounds minlat="42.4276" minlon="1.412368" maxlat="42.65717" maxlon="1.787481"/>
  </osm>

How to mimic full macOS Intellij behavior in Ubuntu
