This guide instructs you in how to unbrick an Amazon Kindle Paperwhite. The consequences of following it are your own responsibility. This method (opening the Kindle and using the serial interface) should be a last resort and should only be considered if other methods fail
There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore
is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules
directory) as well as files that are generated (and regenerated) as artifacts of a build process.
All other files should be in your own global gitignore file:
.gitignore
in your home directory and add any filepath patterns you want to ignore.Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute
.config/git/ignore
for.gitignore
in your home directory, if you prefer.
# The following comments fill some of the gaps in Solargraph's understanding of | |

# You can put this file anywhere in the project, as long as it gets included in | |

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.
Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).
