I'm trying to test out the parent/child relationship but havent throuble getting any results back for has_child queries. I have this mapping

I am trying to run jupyter notebooks in parallel by starting them from another notebook. I'm using papermill to save the output from the notebooks.

In my scheduler.ipynb I’m using multiprocessing which is what some people have had success with. I create processes from a base notebook and this seems to always work the 1st time it’s run. I can run 3 notebooks with sleep 10 in 13 seconds. If I have a subsequent cell that attempts to run the exact same thing, the processes that it spawns (multiple notebooks) hang indefinitely. I’ve tried adding code to make sure the spawned processes have exit codes and have completed, even calling terminate on them once they are done- no luck, my 2nd attempt never completes.

If I do:

To better understand the concept of sigsuspend I made two modifications as following, and got different output messages, which confused me.

The code is from csapp Chapter8 figure 8-42 about sigsuspend.

1. Add line 10 printf("Reap child %d\n", pid);

I want to fetch specific data form JSON . Right now I can fetch all of the data and convert it into JSON format. But I only want to fetch "home_team" and "away_team" of all the sets.

My code to fetch all of the data is:`

Recently I'm studying dumb-init and if I realized correctly it's trying to:

1. runs as PID1, acting like a simple init system(reaping zombie processes)
2. signal proxy/forwarding (which bash doesn't do)

In both here and here they all mentioned that bash is capable of reaping zombie process so I'm trying to verify this but couldn't make it work.

First of all I wrote a simple Go program which spawn 10 zombie process:

The documented example in perldoc IPC::Open2 (read from parent STDIN and write to already open handle) is a simplified version of what I'm trying to achieve. Namely, parent writes a preamble to a output file, then a subprocess writes its output directly to the same file.

I've made a simple child script which reads input lines and prints to STDERR and STDOUT. The STDOUT being the the 'already open handle' from the parent.

I have a GKE v1.17.400 private cluster running with NAT gateway. On the cluster I have multiple application that use google services such as stackdriver, pubsub and cloud sql.

My applications are running on .net-core 2.2. It subscribing and publishing to a Pub/Sub topic.

When having high load I am experiencing issues of connectivity with Google Cloud services.

This issues cause many different logs such as:

Connect timeout with cloud sql:

I have created 3 mongodb instances with below mongod.conf [Primary1,Secondary1,Secondary2]

I have a problem and I don't know where to look for the problem. I'm running debian:buster and I'm trying to set it up as a jellyfin server.

I added the nessecary architecture (amd64).
