I'm getting the following error when I want to run ipython notebook on my macbook. Does anyone know how to fix this? Could you please help me about it?

It appears that your browser is attempting to access the notebook without SSL. Make sure to access the site with HTTPS. For example, when you access the notebook, type in https://127.0.0.1:9999 in your browser. (Or whatever the address of the server is.)
It doesn't recognise the files you're passing it - either:
pass a .pem file (private key) to --NotebookApp.keyfile= and the .crt file (your certificate) to --NotebookApp.certfile=
create a new file by appending your certificate to your key and pass this new file to --certfile.

I use IntelliJ IDEA's bundled database client (DataGrip) to manage my database connections, both local and remote. And using docker to connect to postgres with following settings:
services:
postgresql:
image: postgres:11
ports:
- "5432:5432"
expose:
- "5432"
environment:
- POSTGRES_USER=$user
- POSTGRES_PASSWORD=$pass
- POSTGRES_DB=k$db
After upgrading from Catalina to Big Sur, connection to local db fails and it just shows a connection error message as follows:
[08001] Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
java.net.ConnectException: Connection refused (Connection refused).
When I run docker-compose up, I get the following error:

[1269] Failed to execute script docker-compose
Connecting to remote db's are not broken somehow, they work. Is there anyone came across this problem?
After Big Sur upgrade, I also had a warning whenever I open a new terminal:
zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]?
I did not think they are related but the solution to this problem, explained in this thread, also solved the main postgresql connection issue for me. But my computer keeps restarting occasionally and after this restart, I again get the main problem when I run docker-compose up inside IDE's terminal. I then manually restart and it works. Although not being a permanent soluiton, this solved my problem for now.
Followed the instructions from here: http://www.azerothcore.org/wiki/Install-with-Docker
I used the v8 data
When I run docker-compose up I get the following:

It is likely disc space related, i had same error and there is an error above it that indicates the build ran out of disc space. Works after clearing space it uses over 10gb in my case.
I had the same error when I tried to mount a large file. The solution for me was to create a .dockerignore file containing the name of the directory where the large file was saved.
I am using the latest master branch of the git repo https://github.com/celery/librabbitmq and installing librabbitmq==2.0.0 for Python 3.6 by following the instructions in the readme
Using the development version
You can clone the repository by doing the following:
$ git clone git://github.com/celery/librabbitmq.git
Then install it by doing the following:
$ cd librabbitmq
$ make install # or make develop
This works fine (after installing certain binaries for c compliation in the OS), but when I then make a small a+b add task and call it with add.delay(2,2) it fails with the following error. I looked up and saw that Celery 4 uses json as serializer, so clearly it is not because if pickle serialization
Changing from librabbitmq to pyamqp broker works normally
Same exact situation in both MacOS and Ubuntu 16

This library is not recommended to use as rabbitmq broker with celery. Instead please try py-amqp. this is more maintained and less buggy.
I'm on openbox at Arch Linux and recently installed my system.
I want to use obmenu to configure the menu.
But for some reason, it is not working.
Error at startup:
Traceback (most recent call last):

What is going wrong?
I already solved it. My menu contained an Formatting Mistake!
First you have to remove
rm ~/.config/openbox/menu.xml
and then
cp /etc/xdg/openbox/menu.xml ~/.config/openbox
after that obmenu will work.
Look at the http://obmenu.sourceforge.net/doc.html.
The problem is that you have menu.xml which does't have correct syntax. Evan empty file is wrong.
I'm trying to execute this basic code from Getting Started with Google data:
`import gdata.docs.service
# Create a client class which will make HTTP requests with Google Docs server.
client = gdata.docs.service.DocsService()
# Authenticate using your Google Docs email address and password.
client.ClientLogin('jo#gmail.com', 'password')
# Query the server for an Atom feed containing a list of your documents.
documents_feed = client.GetDocumentListFeed()
# Loop through the feed and extract each document entry.
for document_entry in documents_feed.entry:
# Display the title of the document on the command line.
print document_entry.title.text`
The third line i.e. client.ClientLogin('myemail-id', 'my-password') is throwing an error:
