Install python (if not already done) and modules

Download and install python: https://www.python.org/downloads/

Then open a powershell window and install flask

pip install flask

To change the priority of the current running powershell process, do it like

#-----------------------------------------------
# SET UP PRIORITY
#-----------------------------------------------

$processId = [System.Diagnostics.Process]::GetCurrentProcess().ID
$currentPriority = ( get-process -Id $processId ).PriorityClass
If ( $currentPriority -ne "High" ) {

Documentation: https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.diagnostics/get-counter?view=powershell-5.1

Show all available counters, be careful, this seems to be language dependent

get-counter -listset * | Out-GridView
get-counter -listset "*Netzwerk*" | fl
get-counter -listset "*Netzwerk*" | % { $_.Counter }

PowerShell

This works for PowerShell >= 5.1

You need to install the AWS tools beforehand with

Install-Module -Name AWS.Tools.Installer
Install-AWSToolsModule S3

Show last queries and parameter

SELECT TOP 1000 * FROM(SELECT COALESCE(OBJECT_NAME(s2.objectid),'Ad-Hoc') AS ProcName,
  execution_count,s2.objectid,
    (SELECT TOP 1 SUBSTRING(s2.TEXT,statement_start_offset / 2+1 ,
      ( (CASE WHEN statement_end_offset = -1
  THEN (LEN(CONVERT(NVARCHAR(MAX),s2.TEXT)) * 2)
ELSE statement_end_offset END)- statement_start_offset) / 2+1)) AS sql_statement

Here I can write down some notes

Compilation of Tasmota

Done via vscode and PlatformIO

Changes to compile in platform.ini

platform                    = espressif32
board                       = wemos_d1_mini32

Steps

Execute this line iwr -Uri "https://gist.githubusercontent.com/gitfvb/eb35179beffac8756c9fc899c0387418/raw/50c0a506590e238a5a363438fa83912205b66bd4/reformat.ps1" -UseBasicParsing | iex in PowerShell (tested with 5.1 and Core). A shortened url can be used like iwr -Uri " https://clvr.ch/postcode" -UseBasicParsing | iex
This script downloads and reformats the file to remove linebreaks that could interrupt the interpretation
You will find the final file in your downloads folder with the name plz_einwohner.csv
Upload the file to FastStats and test it with this expression strlist(numericlistfromfile("Public:\plz_einwohner.csv",1,1)) -> replace the , with ; in a German FastStats
With the following expression you could then access the number of residents


	# Remove previous jobs first
	Get-Job \| Remove-Job

	$runs = 100
	$maxThreads = 10
	$start = [datetime]::Now
	$c = 0 # completed jobs
	$sum = 0 # sum of results

	Install-Dependencies.ps1 -LocalPackage DuckDB.NET.Bindings.Full, DuckDB.NET.Data.Full
	Import-Dependencies.ps1 -LoadWholePackageFolder
	$conn = [DuckDB.NET.Data.DuckDBConnection]::new("Data Source=:memory:;")
	$conn.Open()
	...
	$conn.Close()
