Sometimes when you get new project that is under development for few years you see some obsolete tags and branches in git repo. After you getting approval to clean them up you realize that there are too many of them to be removed manually. In my case about a hundred. Lets see how you can script removing all tags and branches older than 3 months.
Remember to backup your repo before doing all the actions below.

Lately I was working on exposing content with LTI (lti_tool_provider). Main idea is that some content (usually related to learning courses) to be exposed to other systems by embedding it with iframe. There is a OAuth authentication system in place so content can't be reused without authorization.

Testing stale designs
Usually visual testing is very effective when website has stable design that should not be broken.
There are projects the whole idea of those is to keep design the same but to migrate the content to new platform. This is where visual regression testing can help a lot to identify very fast what pages are not yet complete and which ones are 100% accurate and can be shown to client.

The Idea of visual testing of your website has been around for a while. This can range from someone manually checking a web page or more for visual defects or automating the process of detecting visual changes. The cause for unwanted visual changes usually comes from CSS stylesheet changes.
For developers, it is important to understand how to incorporate the visual testing into your existing workflow. As usual there are multiple options out there and we will be listing them below. from the easiest to the most complex.

When we have multiple webheads behind the firewall we need to make sure that each of webhead pretend to be main host. So lets say our main website is www.example.com, all our webheads are webheadX.example.com. With following vhost config we can make sure that when request is recieved by webheadX.example.com it is treated same way as it came to www.example.com

Logstash is a great tool to centralize logs in your environment. For example we have several drupal webheads that write logs into syslog. It would be really nice to see those logs somewhere centrally to find out about your system's health status and debug potential problems.
In this article I would like to show how easy to start using logstash for local development.

Panels standard renderer has very flexible undocumented feature of controlling the sequence of panels being rendered.
By default you have possibility to use 'render first' and 'render last' in your content type definition so you already can control what pane should be rendered for example last. Undocumented part is more interesting that is hook_panels_panes_prepared_alter() that runs after all panes were set up. So you can alter the array of panes in which way you can control sequence of panes being rendered. This feature is super handy when you have dependent panes.

Because our IT sphere develops so fast it is so easy to wake up one morning and understand that your knowledge about things got outdated. I have personally decided to restart my habit of reading technical books. Lately I have completed book about Varnish (https://www.varnish-software.com/static/book/) that I highly recommend to everyone dealing with web development.
