More recent resolution:

1. cd ~/../../etc (go to etc folder in WSL).
2. echo "[network]" | sudo tee wsl.conf (Create wsl.conf file and add the first line).
3. echo "generateResolvConf = false" | sudo tee -a wsl.conf (Append wsl.conf the next line).
4. wsl --terminate Debian (Terminate WSL in Windows cmd, in case is Ubuntu not Debian).
5. cd ~/../../etc (go to etc folder in WSL).
6. sudo rm -Rf resolv.conf (Delete the resolv.conf file).
7. In windows cmd, ps or terminal with the vpn connected do: Get-NetIPInterface or ipconfig /all for get the dns primary and

Comprehensive Guide to Data Compression: Huffman Coding, Arithmetic Coding, and Asymmetric Numeral Systems

Introduction

Data compression is a crucial field in computer science, providing the means to store and transmit data efficiently. As digital data continues to grow exponentially, the importance of effective compression techniques cannot be overstated. Compression algorithms reduce the amount of data needed to represent a file or message, enabling faster data transmission and saving storage space. In this guide, we will delve deep into three essential data compression algorithms:

1. Huffman Coding: A widely-used algorithm that assigns variable-length codes to input characters, optimizing the encoding based on character frequency.
2. Arithmetic Coding: A more advanced technique that represents entire messages as fractions within a specific range, allowing for more efficient compression.
3. Asymmetric Numeral Systems (ANS): A modern and innovative approach that combines the strengths of

Recipe: from MQTT to InfluxDB via Node-RED

• 2024-05-16 adds case study explaining how to extract values from topic strings, and how to specify the measurement name in the message payload provided to the "influxdb out" node.
• 2023-12-02 revise graphics to correspond with "influxdb out" node, and explain the pros and cons of InfluxDB 1.8 vs InfluxDB 2.

Introduction

Getting data produced by IoT sensors into a database is practically a mandatory step before effective visualisation (eg dashboards).

This recipe shows you how to get an MQTT payload into an InfluxDB database using three Node-RED nodes. It makes the following assumptions:

#!/usr/bin/bash
get_id() {
    local id=$(xprop -root _NET_ACTIVE_WINDOW)
    echo ${id##* } # extract id
}

get_vm() {
    local id=$(get_id)
    local vm=$(xprop -id $id | grep '_QUBES_VMNAME(STRING)')
    local vm=${vm#*\"} # extract vmname

#!/usr/bin/env perl

use strict;
use warnings;

sub open_file_manager {
	my $vm = shift;
	exec {'qvm-run'} ('qvm-run', '--', $vm, 'exec nautilus --new-window --no-desktop </dev/null >/dev/null') or die "qvm-run exec failed\n";
}
