Adding .gitignore to a Git project

Having files that you don't need to commit but are important to your workflow on a project are always an issue. An example that keeps cropping up is the SCSS caches when you theme a website or your IDE leaves files in the root directory of a project and one that I always have is a temp directory where I can store information or data that is not necessary to the Git master or a remote repositories.

The way to get around Git complaining about these files is use .gitignore what it does it allows the developer to state what directories or files that are not to be seen by Git to add or commit to the repository. The code below allows you to add the .gitignore to an existing repository or one that you have created from scratch.

Drupal website is displaying 500 error or a blank page

Sometimes when moving a Drupal directory it will not copy all the files into the new directory. This can be caused by the way you copy the files and/or the permissions of the files on the webserver. I had a Drupal site that would work perfectly in its original directory but if I copied the Drupal 7 software into another directory I would get a 500 error or the browser would go blank. It took me a while to find the .htaccess was not copying into the new directory. As soon as I manually copied it across the website worked perfectly.

Small smtp email server client on desktop

I need a small smtp client so I could send emails from my Drupal development machine. By using the package msmtp-mta this can be achieved. Firstly install the software, in this example Ubuntu will be used but from what I can see all Unix flavours have this package

~$  sudo apt-get install msmtp-mta

After it is installed then configuration is needed this can be by creating a file called msmtprc and adding some configuration.

After installing it we need to create a configuration file for it. Create a new file by opening vim or nano in the terminal

~$ sudo vim /etc/msmtprc

Then add the configuration you need to access your email smtp server. In this example we will use the Google smtp servers.
