Problem: I have EC2 instance with Linux (Ubunty) and root volume of 10 GB. I have consumed about 96% of the size and now my application responding slow, so I wanted to increase the size to 50 GB. The most important point is, I have data already there and many applications are running on this EC2 instance and I don't want to disturb or stop them. To check the
I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10): encountered RSA key, expected OPENSSH key Executing the same command from the system shell (using the same private key of c
I've used Docker on Windows and macOS for the past couple years. Often, when things got really messed up, I found it faster to use the Reset to factory defaults option in the Docker GUI to do a clean reset than to troubleshoot whatever problem was giving me grief. Now I'm using Ubuntu 20.04 and I can't find this option. I found a long list of commands to rem
I installed a program with pip (e.g. simple-plotter) in windows using the following command: py -m pip install simple-plotter How do I run the program I installed? In Linux, I can just type the command in a terminal, but if I type in windows, I get a "not recognized as an internal or external command" or if I run in Python I get a "No module named" error.

I'd like to add a secondary backup internet connection to my Linux server. I plan to use a USB LTE modem for this purpose. Because this cellular connection will be metered, I want to limit the amount of data that can be consumed to the absolute minimum necessary. I have a custom server application that I can make any changes to. It has a few tasks where unin
I'm trying to make a discord bot, and when I try to load a .env with load_dotenv() it doesn't work because it says Traceback (most recent call last): File "/home/fanjin/Documents/Python Projects/Discord Bot/bot.py", line 15, in <module> client.run(TOKEN) File "/home/fanjin/.local/lib/python3.8/site-packages/discord/client.py", line 708, in run return f
According to https://lwn.net/Articles/629155/ the Linux kernel, "can only forward something between 1M and 2M packets per core every second" - but how good Linux is at scaling across dozens of cores then? Say I have a multiqueue(128 rx+tx pairs) 100gbps NIC on multicore CPU - will Linux be able to saturate 100gbps NIC i.e. scale "between 1M and 2M packets pe
