Daily: VS Code Error NSOSStatusErrorDomain

If you got an NSOSStatusErrorDomain Error, when you start VS Code from the command line

❯ code
[0309/] SecCodeCheckValidity: Error Domain=NSOSStatusErrorDomain Code=-67062 "(null)" (-67062)

You should do this: codesign --force --deep --sign -

Daily Azure: Migrate a Storge Account


Migration is done via azcopy:

  • download souce container to local folder
  • upload local folder to destination container

Get AzCopy

Here is the script install-azcopy.ps1:

# Download and extract

$URI = ""
$DST = "~\AppData\Local\Programs\AZCopy\"

Invoke-WebRequest -Uri $URI -OutFile -UseBasicParsing
Expand-Archive ./ ./AzCopy -Force

# Move AzCopy
mkdir ~\AppData\Local\Programs\AZCopy
Get-ChildItem ./AzCopy/*/azcopy.exe | Move-Item -Destination "~\$DEST"

# Add AzCopy to PATH
$userenv = (Get-ItemProperty -Path 'HKCU:\Environment' -Name Path).path
$newPath = "$userenv
New-ItemProperty -Path 'HKCU:\Environment' -Name Path -Value $newPath -Force

# Clean the kitchen
del -Force

Call the script

First call should use -login to authenticate

.\copy.ps1 demo-folder-1 -login

Then, following commands dont need the login

.\copy.ps1 demo-folder-2

Daily: Running Microsoft SQL-Server in Docker


Using Docker is an effortless way to launch and run an application/server software without annoying installation hassles: Just run the image and you’re done.

Even if it’s quite an uncomplicated way of looking at it, in many cases it works just like that.

So, let’s start with using Microsoft SQL Server as a database backend. We will use a docker image from Microsoft. Look here to find out more.

docker	run                                       \
			--name mssql-server       \
			--memory 4294967296       \	
			-e "ACCEPT_EULA=Y"        \
			-e "SA_PASSWORD=secret"   \
			-p 1433:1433              \


Error: program requires a machine with at least 2000 megabytes of memory

Start the docker container as described on the Docker Hub Page: How to use this Image

❯ docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=secret" -p 1433:1433

Depending on how your docker environment is configured, this could bring up an error:

SQL Server 2019 will run as non-root by default.
This container is running as user mssql.
To learn more visit
sqlservr: This program requires a machine with at least 2000 megabytes of memory.
/opt/mssql/bin/sqlservr: This program requires a machine with at least 2000 megabytes of memory.

As the error message states, the MS SQL server needs at least 2g of RAM. So, you must assign your Docker VMs more memory. This is configured in the Docker Dashboard.

Hint: Docker has two ways of running containers:

  • using Windows Container
  • using WSL (Windows Subsystem for Linux)

You can change the way with the context menu of the docker symbol in the task bar:

With Linux Containers (using WSL as backend), you must configure the containers via a file .wslconfig.

This file is in the folder defined by the environment variable

To open the file, run the command:

From Command Promptnotepad

Edit the content and change the memory setting


Restart WSL with the new settings.

❯ wsl --shutdown

Start Container again, now everything should work

❯ docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=secret" -p 1433:1433

Daily: Build a Development Environment with Docker and VS Code


Working with different software (samples, compilers, demos) always requires an adequate environment.

Because i don’t want to pollute my normal environment (my running PC), i decided to use a virtual environment with Docker.

Luckily, VS Code supports this by using remote containers and working fully within these containers.

The Files

	"dockerComposeFile": [

	"service": "app",
