    Minimal Mistakes Jekyll theme

    Minimal Mistakes Jekyll theme

    Jekyll theme for building a personal site, blog, project documentation

    A flexible two-column Jekyll theme. Perfect for building personal sites, blogs, and portfolios. Everything from the menus, sidebars, comments, and more can be configured or set with YAML Front Matter. Built with HTML5 + CSS3. All layouts are fully responsive with helpers to augment your content. Free to use however you want under the MIT License. Clone it, fork it, customize it, etc. Settings that affect your entire site can be changed in Jekyll’s configuration file: _config.yml, found in the root of your project. If you don’t have this file you’ll need to copy or create one using the theme’s default _config.yml as a base. Take a moment to look over the configuration file included with the theme. Comments have been added to provide examples and default values for most settings. Bundled as a "theme gem" for easier installation/upgrading.

    SAM
    SAM is a command line tool (for Slackware Linux) which uses a stack to provide control of variables, including PATH, and functions. To do this it uses a set of scripts, functions and compiled code. The result is a command line environment that changes the way you see and thus changes the way you think. It has helped me to write more and better shell code. Perhaps it will help you also.
