Git tips

O git rebase é usado para modificar o histórico de commits de uma branch. Ele reorganiza os commits de forma linear, movendo os commits da sua branch atual para o topo da branch de destino. Isso pode ser útil para integrar as mudanças de uma branch para outra de forma mais limpa, reorganizando e simplificando o histórico de commits.

Aqui está um exemplo básico de como usar o git rebase:

  1. Certifique-se de estar na branch que deseja modificar (por exemplo, feature):

    git checkout feature

  2. Atualize sua branch feature com as últimas mudanças da branch de destino (main, por exemplo):

DigitalOcean without internet

After almost two weeks since I raised this issue, I was finally able to resolve it. The problem occurred in the first place because different packages got uninstalled somehow when I rebooted. This includes cloud-init, ufw and landscape-common. There is probably more that I haven’t noticed yet. Let’s start with the internet connection, this is how I fixed it:

  • Step 1. I created file “/etc/udev/rules.d/70-persistent-net.rules” and added
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="b2:fe:09:35:6e:57", NAME="eth0"

as I mentioned previously. Note that MAC address used above can be found here: “/etc/netplan/50-cloud-init.yaml”

  • Step 2. Run “sudo reboot” and check that eth0 interface persists by running “ifconfig -a”

How to create swap file.

Step 1 -- Checking the System for Swap Information

Before we begin, we can check if the system already has some swap space available. It is possible to have multiple swap files or swap partitions, but generally one should be enough.

We can see if the system has any configured swap by typing:

sudo swapon --show

How to delete duplicate nodes and their relationships in neo4j with cypher?

How to delete duplicate nodes and their relationships in neo4j with cypher based on a property of that node?

The problem is easy to understand. We have 'duplicate' nodes in our database based on the 'id' field on the node properties.

Well this sounds easy enough, until you have to actually do it.

First step

My first attempt was to try and figure out which nodes are actualy duplicate (based on a property on the node). This seems to be pretty straightforward.

Cypher:
