Export mapping files generated by Fluent NHibernate

If you are using  NHibernate, you probably also heard about Fluent NHibernate which allows you to create your object-relational mapping from a mix of conventions and code instead of using error-prone XML files. Although you’re using a completely different API under the hood the same old XML files still exist. Sometimes it would be handy to view the NHibernate mapping files generated by Fluent NHibernate.It turns out that this is quite easy and you will just need to add a call to the method ExportTo() and then the mappings will be created in the location specified.

   1:  private static ISessionFactory CreateSessionFactory() 
   2:  { 
   3:     string outputdir= Path.Combine(System.Environment.CurrentDirectory, "Mappings"); 
   4:   
   5:      return Fluently.Configure() 
   6:        .Database(SQLiteConfiguration.Standard.InMemory().ShowSql()) 
   7:        .Mappings(M => M.FluentMappings.AddFromAssemblyOf<SessionFactory>() 
   8:        .ExportTo(outputdir))
   9:        .BuildSessionFactory(); 
  10:  }
  11:   


Remark: Make sure that the directory exists where you want to output the generated mapping files.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...
