Had you visited this blog recently, you may have noticed that the blog’s theme has changed. Here is a quick note on how I changed the theme of this blog from cayman-hugo-theme to PaperMod. For a little background, Hugo themes are installed as git submodule. Want a quick recap on how to use Git Submodule? Here is a good content [0]. First, the current theme needs to be removed: $ git submodule 4a924cef54081b61530a30bd69d442ae99916561 themes/cayman-hugo-theme (heads/master) $ git submodule deinit "themes/cayman-hugo-theme" $ git rm "themes/cayman-hugo-theme" $ git commit -m 'remove theme cayman-hugo-theme' Add a new theme, PaperMod [2] as the submodule....

When I first started to use AWS CLI, I felt overwhelmed, and I wondered how long it would take me to be familiar with the tool.

Anyway, like many thing I’ve learned about Linux, I learned and could retain the information better with practice and document....

I normally use gzip for file compression. However, there is time when you want to share a compressed file with Windows users and you want to avoid them cursing at you. One good solution is to use zip compression (even if I had to learn how to do it on a Linux machine).

I’ve been running a few VMs on Proxmox, including a Pfsense VM, for over a year without a single issue. This evening, however, I noticed that I wasn’t able to access any local DNS records due to the VM hosting DNS server was not responding. On checking the Proxmox console, I could see that that VM with ID 102 was definitely not responding. So, I tried to reboot, stop and even reset....

This is just a quick note on how to run Redis as a container using Podman on Ubuntu 22.04 (i.e. there will be no mention about SELinux.) Create a persistent volume for the Redis container I like storing all data/volume for containers under /srv/data. So I’ll create a sub-directory called redis-data under the same location. # mkdir -p /srv/data/redis-data Pull the Redis image # podman pull docker.io/redis Create and run the Redis container # podman run -d --name redis_server \ -v /srv/data/redis-data:/var/redis/data \ -p 6379:6379 redis Create systemd service for the Redis container I like creating a systemd service to enable/start the container....
