I am working on a program which fetches strings like these:

Docker daemon comes with an embedded DNS server. It resolves local Docker swarm and network records and forwards queries for external records to an upstream nameserver configured with --dns 1.

Docs say you can set an IP address for this upstream nameserver with --dns=[IP_ADDRESS...]. The default port used is 53.

Can I configure the port used as well?

My host's /etc/docker/daemon.json shows "dns": ["10.99.0.1"],. Is there a way for me to specify something like "dns": ["10.99.0.1:53"], so that dockerd always knows to forward DNS queries to port 53?

In my case, 10.99.0.1 is the IP of a localhost bridge interface. I run a local DNS caching server on this host. So DNS queries sent to 10.99.0.1:53 work. But dockerd forwards queries originating from containers connected to user-defined bridge networks (created with docker network create) to non-standard ports it picks. See terminal output below.

"toogle" is a Docker container connected to a Docker network I created with docker network create. 127.0.0.11 is another loopback address. DNS queries originating from within Docker containers connected to user-defined Docker networks are destined for this IP.

Is Docker's embedded DNS server actually running?

DNS queries are routed by toogle's firewall rules this way.

I have this code that is supposed to see whether it's the weekend or not and if it is not the weekend, then it will print a certain line. However, I am getting an error with the second if statement. here is my code

I am trying to run a simple MPI example on two computing nodes node1 and node2, which are virtual machines I just created on Oracle Cloud. (It is the first time I used Oracle Cloud...) The system is Ubuntu 20.04. What I've done include:

• node1 and node2 have the correct MPI environment (OpenMPI-4.1.0) under the same path. $PATH and $LD_LIBRARY_PATH have also been set. I can successfully run the MPI example on a single node.
• Passwordless login between node1 and node2 has been setup. I can use ssh node1 and ssh node2 to connect one node to another.
• There is a hostfile (hosts2) on the two nodes under the same path ($HOSTFILE_PATH/hosts2) containing

I am learning about image pyramids by following the official Python tutorials here.

I get the following error as well as a warning that highlights the one-before-the-last ref to cols.

Can someone please help me understand what the error is caused by and how I can change the code to resolve the warning on real = np.hstack((A[:, :cols/2], B[:, cols/2:]))?

I have a database named library and it contains two tables named teacher and student. I have a JFrame named Signup and it contains various fields to signup.There is also a option to signup as "Teacher","Student" in a JComboBox.I can choose only one option and it will save in the selected database. means if i choice "Teacher" it will save in teacher table. I want to check Unique Username.But by clicking One JButton named REGISTER NOW How can I Check the Unique Username from the both table named teacher and student ? Means I select signup as teacher so I must check unique username from table teacher and if I select signup as student so I must check unique username from table student and show me if the username already exists in the table by clicking the button to register. My code is given below:
