Welcome! I'm Lorna: engineer, author and speaker. I'm a Developer Evangelist and I love technology and sharing technology with others. On this site you'll find my blog and links to all the other things I think you (or I) might need to know about me - my opinions are my own and not those of my employer or any other organisation. If you'd like to get in touch, I'd be delighted to hear from you.

When working with serverless actions, often we'll still need to access some sort of service, whether it's object storage, a database, or whatever. Here's a quick overview of how this works for IBM Cloud Functions (plus some gotchas ....) Continue reading

React to Database Changes with OpenWhisk Actions
One of the best features of CouchDB is its change feed which allows us to get a feed of the changes happening on our database. It's also possible to have a serverless function (examples are for IBM Cloud Functions but should also work for Apache OpenWhisk) that fires in response to activity on that change feed. I have a database of events that I want to react to when they happen, but the change feed doesn't include the actual document that was added - but you can add one of the built-in functions to a sequence to make that happen. This post will show how to achieve this by wiring up a built-in action to fetch the document with another action of our own that then handles the data. Continue reading
