Today we will install Ruby on Rails (RoR) on a Debian Linux operating system (Ubuntu 18.04 LTS). With that said, RoR is compatible with other operating systems with just a few tweaks. This blog will assist you in installing RoR with a simple step-by-step process. Your installation may differ, for other operating systems refer to this site.
Recently, while working with a customer, I saw a really cool use of PagerTree’s Stakeholder Notifications to send messages into a Slack channel. They did this by using the Slack’s Email to Slack integration along with PagerTree’s Stakeholder notifications. Today I’d like to share with you how they did it.
Today, we are excited to announce PagerTree has added 3 new chatbot services including Mattermost, Microsoft Teams and Google Hangouts Chat (this is in addition to our core Slack notification channel).
Chatbots are available on all pricing tiers free of charge! 😄 If you don’t already have an account, sign up for a free-trial now.
