gpg cryptic errors
I started getting the error below after upgrading to gpg (GnuPG) 2.1.21 .
gpg: signing failed: Timeout
gpg: signing failed: Timeout
This was confusing at first, but the timeout was caused by gpg showing a password prompt that takes the full screen of the terminal, and after a period of time, it returned to the command line showing the timeout error.
I didn't notice the password prompt at first because I was working on multiple terminals and only saw the timeout error at the end.
Another error that I encountered earlier was:

Getting started with Linux kernel development

Getting started with Linux kernel development

Prerequisites

The Linux kernel is written in C, so you should have at least a basic understanding of C before diving into kernel work. You don't need expert level C knowledge, since you can always pick some things up underway, but it certainly helps to know the language and to have written some userspace C programs already.

It will also help to be a Linux user. If you have never used Linux before, it's probably a good idea to download a distro and get comfortable with it before you start doing kernel work.

Lastly, knowing git is not actually required, but can really help you (since you can dig through changelogs and search for information you'll need). At a minimum you should probably be able to clone the git repository to a local directory.

Creation of CentOS-8 Custom ISO

ISO Creation from Scratch

In this tutorial we are going to look into creation of CentOS ISO based on CentOS 8. There are few slight difference between the folder structure from CentOS 7. In CentOS 7 isolinux contains directly Packages without any parent folder and every rpm will be under single folder. But in CentOS 8 it would segreagated into two separate folder such as BaseOS and AppStream. And those configuration defined on media.repo file present in the iso file.

  • To Create ISO we need to create necessary folder struture like mentioned below.
mkdir -p ~/kickstart_build/isolinux/{BaseOS,AppStream}/Packages

how to pull from docker hub using podman/buildah
On void linux.
Under `/etc/containers/` there is a file called `registries.conf`. It is complemented by `man 5 containers-registries.conf`.
Change (for me lines 11-12) which say

In preparation for macOS 10.15, this list identifies 32-bit apps in the Applications folder and returns the list to an extension attribute in Jamf Pro. The returned list may include Xcode because it contains an app with a non-standard file in place of a binary deep within its app bundle. This may be ignored.

# create a list of paths in the Applications folder for testing

Programmatically access your Firefox bookmarks
"""
A script to automatically export bookmarks from Firefox's SQLite database.
There does not seem to be a programmatic way to get Firefox to export its bookmarks in
the conventional HTML format. However, you can access the bookmark information directly
in Firefox's internal database, which is what this script does.
Always be careful when working with the internal database! If you delete data, you will
likely not be able to recover it.
