Android For GitOps Writing Workflow

My sister got me a Logitech K480 Bluetooth keyboard for Christmas! What makes me truly excited about this gift is the mental exercise of using my Android phone as a content creation device. It’s a bit of a stretch, but with this kind of powerful technology in our pockets, we should be able to leverage these devices more productively. My writing workflow is focused around markdown stored in git (backed by Gitlab or Github), rendered using Hugo, and leveraging Netlify’s platform for integration and deployment.

Ansible Configuration

Use Ansible http:// [[|Fedora Ansible GIT Repository]]: Good example of GIT usage. Roles are not heavily used, as that is a 1.2 feature. Fedora Reasoning for Ansible: Method of having multiple distro variable: Ansible Configuration Basic Security Lockdown (minimum services, sudo configuration, etc) Useful scripts (automatic update, or maybe a nice “motd” generator with number of packages to update, system load, etc.) Customization for site (local users, sudo config, sshd config, webmin configuration) Ansible Roles ansiblemaster (bootstrap an environment) ansiblepull deployment (pxe/tftp/dhcp for PXE config) pkgcache (apt-cacher) pkgcache-feeder (for yum primarily…makes sure RPMs never removed) authmaster (https://help.

Web 0

Recently have discovered a diverse community of individuals rejecting the current Web2 (social media) and Web3 (Blockchain/NFT/metaverse/whatever else is bucketed in Web3) and back to the non-commercial, unique roots of the Internet that existed before the widespread centralization of the Internet. A time when site’s goals were not to get you addicted to the dopamine hits of likes and aggravation, but to simply express the creativity and interest of their creators.

OpenSCAD Coding Guidelines

OpenSCAD is a 3D CAM/CAD environment. Instead of GUI design utilities, a coding environment is used to describe objects. Parametrized designs allow for easy customization. Overall Goals Parameters in the design should be minimal. Individual statements should be clear in what they do…calculations should be done with separate variable assignments. Follow procedural as best as possible. Each module should be given ALL variables as input fields (clear separation of global and local variables).
