add line number in a file using vim

I just needed to insert line numbers in a file in vim. Thanks to https://vi.stackexchange.com/questions/8179/replace-a-pattern-with-current-line-number I now know how to do this by replacing the start of every line using the following command: :%s/^/\=printf("%4d: ", line('.')) which adds the current line number formatted to 4 characters with leading spaces.

setting up MacPorts apache2 with virtual hosts and PHP 5.6

I just needed an apache webserver with PHP 5.6 and some virtual hosts on my Mac running OSX El Capitan.

Note to self: To start or stop the Apache webserver on Mac OSX El Capitan, use the terminal: sudo apachectl start sudo apachectl stop sudo apachectl restart The configuration is found in /etc/apache2/httpd.conf. The default DocumentRoot directory is /Library/WebServer/Documents. Additional configuration files should be put in /etc/apache2/other/*.conf files.

OpenShift configure which branch to deploy

Note to self: this is a copy from the OpenShift documentation: Configuring Which Branch to Deploy By default OpenShift deploys the master branch when you do a git push (when automatic deployments are enabled). You can change this behavior using the rhc app-configure –deployment-branch command, where is the new branch to deploy. $ rhc app-configure --deployment-branch # Master is the Default $ rhc app-configure myapp --deployment-branch new_branch Configuring application 'myapp' .
