Trackpoint + extra mouse buttons + mousepad all work with this line in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.proto=bare"
sudo update-grud

However.. Mouse gestures don't work anymore with this setting.

Section "InputClass"
    Identifier "nathan touchpad catchall"
    MatchIsTouchpad "on"

	I got this error after creating an event source under the Application Log from the command line using "EventCreate". This command creates a new key under: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application

	If you look at the Key that's been created (e.g. SourceTest) there will be a string value calledEventMessageFile, which for me was set to %SystemRoot%\System32\EventCreate.exe.

	Change this to c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\EventLogMessages.dll

	Delete theCustomSource and TypesSupported values.

Leermomenten Kubernetes + Azure:
	Webapp in docker op poort 80 hosten en dan in kube onderbrengen op azure werkt niet!
	Wel als je een hogere poort gebruikt, 5000 bv
	Backend port van de cluster ip poort wordt door azure niet goed ingevuld bij de load balancer als je een nieuwe service aanmaakt. Je moet dan handmatig de backend poort invullen.

De looptijd van integratietesten die b.v. het aanmaken van een database of het publiceren van events testen kan flink uiteenlopen afhankelijk van het aantal testen dat parallel uitgevoerd wordt of de snelheid van de (build) machine. Met Polly kan je heel elegant op een circuit breaker achtige wijze de asserts uitvoeren.

Voorbeeld:

[TestCase("T001")]  
[TestCase("ImportedDataSummary")]  
public void Has_created_tables(string tableName)  
{  
 // Check if T001 table and retry for up to 26 seconds with different intervals
