Neutron | contained Node and NPM environment | Runtime Evironment library

I'm final student who research and implement Openstack Victoria. When I configure Project: Octavia - Loadbalancer on multi-node - CentOS8, I have a issue. Seem like octavia.amphorae.drivers.haproxy.rest_api_driver couldn't connect to Amphora instance and port 9443 didn't run on my Network Node aka Octavia-API. In controller node, the amphora instance still running nornally. I follow https://www.server-world.info/en/note?os=CentOS_8&p=openstack_victoria4&f=11 to configure my lab. This is my cfg file below, pls help me to figure out. Regards!

I created lb_net in type vxlan and lb-secgroup, when i use command to create lb it still pending-create:

I am trying to split by date and event columns. It is impossible to search for ". " some lines contain multiple sentences ending with ". " Also, some lines don't start with dates. The idea of ​​the script was to use a regexp to find lines starting with the fragment "one or two numbers, space, letters, period, space" and then replace "point, space" with a rare character, for example, "@". If the line does not start with this fragment, then add "@" to the beginning. Then this array can be easily divided into two parts by this symbol ("@") and written to the sheet.

Unfortunately, something went wrong today. I came across the fact that match(re) is always null. I ask for help in composing the correct regular expression and solving the problem.

1 June. Astronomers report narrowing down the source of Fast Radio Bursts (FRBs). It may now plausibly include "compact-object mergers and magnetars arising from normal core collapse supernovae".[3][4]

The existence of quark cores in neutron stars is confirmed by Finnish researchers.[5][6][7]

3 June. Researchers show that compared to rural populations urban red foxes (pictured) in London are mirroring patterns of domestication similar to domesticated dogs, as they adapt to their city environment.[21]

The discovery of the oldest and largest structure in the Maya region, a 3,000-year-old pyramid-topped platform Aguada Fénix, with LiDAR technology is reported.

17 June. Physicists at the XENON dark matter research facility report an excess of 53 events, which may hint at the existence of hypothetical Solar axions.

I got the following code for a project:

I wish to have both Subscripts and Superscripts on my character vectors, relative to the X and Y values on a plot.

For example, the X values are the superscript and Y values are the subscript.

Here's an example of what it should look like:

I have tried pasting superscripts then plotting these, although it hasn't worked out like expected

Code for plot:

I am trying to figure out how to fill between two lines that are on different scales & axes of subplot, however, I have not been able to figure out how to do this.

I have tried following the answer here for a similar question, but the formula supplied in the code doesn't work on my dataset and based on the responses from the author of that question the equation doesn't appear to work when the x limits are changed.

The following image is what I am after (created in Photoshop):

However, using the code below, I get:

I have bee trying to create a exam paper parser. I am struggling to make a regular expression for capturing the question in-between 2 consecutive numbers. Here is a sample of the paper:

I'm trying to extract IP addresses from a range with Terraform.

For example, I defined this range 192.168.1.10-192.168.1.20 as a string and I would like to get a list like this: [192.168.1.10,192.168.1.11,…,192.168.1.20].

I checked for Terraform functions but didn’t find a way to do that.

Is this possible?

For further context, I am deploying MetalLB in a Kubernetes cluster and need to define the VIP range as a string like this 192.168.1.10-192.168.1.20. The Kubernetes cluster is deployed on OpenStack and I need to configure Neutron OpenStack port to accept all IP addresses from this range:

I'm working on a very small model with less than 2K parameters:

I have successfully deployed openstack packstack (all-in-one) in single VM. I'm running Centos7 VM. Everything work well and able to instantiate VM over native OVS networking. I plan to have OVS-DPDK enable in my openstack. I have gone through some documentation but still not clear how to enable it. I understand Openstack Queens OVS is already DPDK support.I have seen people asking the same but no answer and I would like again to request on how I can have DPDK support to be enabled over my running openstack. Few method to change neutron configuration file or by deploying SDN controller. Hope no need to redeploy..anyway further advise would be much appreciated.
