I'm trying to build a cluster to test stuff before i apply them to out production cluster. We're using Ceph Nautilus so i decided to install Nautilus first as well. Used the docs below: https://docs.ceph.com/en/latest/install/manual-deployment/ Everything seemed to go fine. I installed 3 monitors, generated the monmap copied keyrings to other monitors, started services and they are all up. But when i type ceph -s to check the cluster status it just gets stuck forever without any output. Any command that uses the word "ceph" in it just gets stuck. As a result i can't continue to build the cluster since i need to be able to use ceph commands after monitor deployments to install other services. Systemctl outputs are the same for all 3 monitors in the current state:

...

I have a dataframe in Pyspark describing the state of a service as follows. The frequency rate at which I receive an update of the service status is not constant.

status timestamp_of_update OK 2020-01-01 14:30:00 OK 2020-01-01 14:15:00 Broken 2020-01-01 14:10:00 Broken 2020-01-01 14:00:00 Broken 2020-01-01 13:40:00 Broken 2020-01-01 13:35:00 OK 2020-01-01 13:15:00 OK 2020-01-01 13:00:00 OK 2020-01-01 12:40:00

Based on this, I would like to create a column that gives me the time since the last update that satisfies the following conditions:

1. If the status is "OK" and the service has been running without issues, then the time diff since the last update.

2. When the status is reported as "broken" I want the time since the service went down.

3. When the status gets back to OK again, then the difference should be zero.

So, the final dataset should look like something like this.

status timestamp_of_update time_gone_by OK 2020-01-01 14:30:00 15mins OK 2020-01-01 14:15:00 0mins Broken 2020-01-01 14:10:00 55mins Broken 2020-01-01 14:00:00 45mins Broken 2020-01-01 13:40:00 25mins Broken 2020-01-01 13:35:00 20mins OK 2020-01-01 13:15:00 15mins OK 2020-01-01 13:00:00 20mins OK 2020-01-01 12:40:00 NaN

Anyone has an idea how to do this in PySpark? Thanks!

I have a fresh Pop!OS 20.10 (Basically Ubuntu for those not familiar with Pop!OS). I've installed Apache, php 7.2, 7.4 & 8.0. Each version is running as FPM and each service is up and running. I have several vhosts setup and using FilesMatch to indicate which version of php should run on each host.

The problem is they all show php 8.0 when running phpinfo() no matter what the vhost config says. Anyone have any ideas?

Here's one of the host files:

creating a pizza ordering program for IT class, almost finished with it but I'm currently stuck with a problem that I can't seem to fix or don't know how to. As the user is finished choosing their pizza it was suppose to add up the total cost of the pizza they have chosen but the problems is they don't add up the instead the price stays the same

When I open large audio files, I get an out of memory error.

I know this method isn't common, so I thought I have to ask a real boffin.

Would you please help me? :) I've been struggling with this problem for like a week and couldn't solve it. my problem is - I can't pass data between my two view controllers, let me explain myself better: I've got one VC which is the main VC that has the Clock animation, and I've got another VC which takes care of the SettingsVC. now no matter what I do (delegation, anything..) it doesn't let me to pass my UILabel's text to the main VC. I beg for a help since I can't keep going with my app and I'm about to finish it.

I am trying to get deploy a FlaskApp with Gunicorn/WSGI/Nginx. I've been trying to get this to work for awhile and can't find any thing other than the Digital Ocean guides that I've followed to a T. Below are my files I've got in their current states. I have tried several different tweaks to mywebapp.service file because I am pretty sure this is where my problem lay. I can run /bin/gunicorn --workers 3 --bind 0.0.0.0:8000 -u nginx -g nginx wsgi and gunicorn will work. I'm pretty sure its some small possibly fundamental thing that I am missing but I lost. My nginx user owns the app directory.
