How do I use multiple GitHub accounts on the same computer? This approach is a sanity saver when working on various projects from numerous clients. Create a new SSH key on macOS. (Try on other OSes; YMMV) ssh_key_gen() { if [ $# == 0 ]; then echo "Usage: ${FUNCNAME} [EMAIL] [KEY_NAME]" echo "1. Generate a key" echo "2. Copy the public key to the clipboard" return fi email="$1" key_name="$2" rsa_key_name="id_rsa_${key_name}" rsa_key_path="${HOME}/.ssh/${rsa_key_name}" ssh-keygen \ -t rsa \ -C "${email}" \ -f "${rsa_key_path}" \ cat "${rsa_key_path}.pub" | pbcopy ssh-add "${rsa_key_path}" ssh_config_entry=$(cat <<-END Host github.com HostName github.com User git IdentityFile "${rsa_key_path}" END ) ssh_config_path="${HOME}/.ssh/config" if ! grep "${ssh_key_name}" "${ssh_config_path}"; then echo "Key already exists in ${ssh_config_path}" else echo "${ssh_config_entry}" >> "${ssh_config_path}" fi } ssh_key_gen your.email@domain.com your_key_name Enter your passphrase. Add a new ssh key in GitHub. Now, test your key by cloning a repository. To switch between keys run these commands. ...

Introduction Both writers and programmers have difficulty setting context. Missing context plagues both prose and code. I’m guilty of cutting things short in the name of efficiency. I recently presented Structurizr and PlantUML without specifying the context for my team and dove directly into the code & tools. I should have taken a moment to explain why clear diagrams are essential, but alas, I did not. I’ll do better next time. In the following paragraphs, I’ve laid out my view on Content & Context and will close with some solutions. ...
