Nautilus | The open-core for enterprise-grade algorithmic trading | Architecture library

I've been trying to get the following to work without success:

Dockerfile

I have the following list:

I deployed a single-user dask-jupyter helm chart on a k8s cluster (https://github.com/dask/helm-chart/tree/main/dask).

$ helm ls

I am trying to learn python and I have just gotten past conditional statements and I'm working on creating my own functions.

Would you mind telling me what I am doing wrong that I have to write the convoluted print statement at the end that calls all of my functions one by one?

Also any style tips would also be greatly appreciated.

Thanks in advance for anything you can provide.

I'm currently testing OS and version upgrades for a ceph cluster. Starting info: The cluster is currently on Centos 7 and Ceph version Nautilus. I'm trying to change OS with ubuntu 20.04 and version with Octopus. I started with upgrading mon1 first. I will write down the things done in order.

First of I stopped monitor service - systemctl stop ceph-mon@mon1

Then I removed the monitor from cluster - ceph mon remove mon1

Then installed ubuntu 20.04 on mon1. Updated the system and configured ufw.

Installed ceph octopus packages.

Copied ceph.client.admin.keyring and ceph.conf to mon1 /etc/ceph/

Copied ceph.mon.keyring to mon1 to a temporary folder and changed ownership to ceph:ceph

Got the monmap ceph mon getmap -o ${MONMAP} - The thing is i did this after removing the monitor.

Created /var/lib/ceph/mon/ceph-mon1 folder and changed ownership to ceph:ceph

Created the filesystem for monitor - sudo -u ceph ceph-mon --mkfs -i mon1 --monmap /folder/monmap --keyring /folder/ceph.mon.keyring

After noticing I got the monmap after the monitors removal I added it manually - ceph mon add mon1 --fsid

After starting manually and checking cluster state with ceph -s I can see mon1 is listed but is not in quorum. The monitor daemon runs fine on the said mon1 node. I noticed on logs that mon1 is stuck in "probe" state and on other monitor logs there is an output such as mon1 (rank 2) addr [v2::3300/0,v1::6789/0] is down (out of quorum) , as i said the the monitor daemon is running on mon1 without any visible errors just stuck in probe state.

I wondered if it was caused by os&version change so i first tried out configuring manager, mds and radosgw daemons by creating the respective folders in /var/lib/ceph/... and copying keyrings. All these services work fine, i was able to reach to my buckets, was able to open the Octopus version dashboard, and metadata server is listed as active in ceph -s. So evidently my problem is only with monitor configuration.

After doing some checking found this on red hat ceph documantation:

If the Ceph Monitor is in the probing state longer than expected, it cannot find the other Ceph Monitors. This problem can be caused by networking issues, or the Ceph Monitor can have an outdated Ceph Monitor map (monmap) and be trying to reach the other Ceph Monitors on incorrect IP addresses. Alternatively, if the monmap is up-to-date, Ceph Monitor’s clock might not be synchronized.

There is no network error on the monitor, I can reach all the other machines in the cluster. The clocks are synchronized. If this problem is caused by the monmap situation how can I fix this?

I know of several file managers such as Midnight Commander that provide a GUI on console. However, if I need to Copy or Move a file, it requires me to type the path rather than navigating to the folder in GUI and choosing to paste, as in any typical GUI File Manager such as Nautilus.

I was wondering if there is a console based utility in Linux that would allow me to cut files, navigate to the desired target folder, and then paste them in the desired target folder? I am not looking for mv because I don't know beforehand where I want the files to land.

A custom script that temporarily stores the absolute paths of the files readlink -f $0 >> ~.cache until I call the command again mv $(<~.cache) .; rm ~.cache would probably do the trick. Does such a utility already exist?

Thanks.

I installed docker container from Githunb. It is working smoothly via run_docker.sh command. Everything is working as desired but I am not able to locate the input files present at directories mentioned in "run_docker.sh" script.

So I run the command as mentioned at Github page

I am using hardhat with ethers on rinkeby to test a smart contract that makes a a get request to a local chainlink node. I can observe on the node dashboard that the request is fulfilled.

I am struggling to write a test that waits for the 2nd fulfillment transaction to be confirmed.

I see similar tests in the SmartContractKit/chainlink repo tests

I am working on the project where I have to schedule the events. While adding events user can select multiple days on a checkbox. You can view the figure here.

Select the days when the event will occur.

for this I have have created database as
