Serverless for Vampires

Permalink - Posted on 2017-07-27 20:24

Ok, as a quick warning, this is a pretty stupid demo. I mean, I know that’s my thing - I’m the person who makes demos with cats. But this really pushes it a bit too far. I was bored a week or so ago and found an interesting API, the Sunrise Sunset API. This is a free API that returns sunrise and sunset times for a specific location. So obviously I saw that and thought it would be the perfect kind of service for vampires.


Using Postman with OpenWhisk

Permalink - Posted on 2017-07-24 17:33

For a while now I’ve been a huge fan of Postman. If you’ve never heard of it, it’s an incredibly powerful tool for working with APIs. I know a lot of folks like to use Curl at the command line for doing HTTP calls, but I much prefer a visual tool instead. Plus, Postman makes it much easier to save and organize API tests for use later. It’s free, supported everywhere, and I strongly recommend it.


Great Reminder of Persistence in Serverless

Permalink - Posted on 2017-07-18 16:11

Today I ran into a great bug. By “great” I mean it totally confused me but as soon as I realized what I was doing wrong, I knew it would be a great thing to blog about as a reminder to others. I don’t think this applies just to OpenWhisk, but to serverless in general. Ok, so what did I do? I was working on a sample action that simply returned an array of cats.


Creating a Serverless Meetup API Wrapper

Permalink - Posted on 2017-07-17 17:58

Yesterday I was doing some research into serverless meetups when I encountered something that bugged me about the Meetup.com web site. Specifically, this: I couldn’t search for meetups until I logged in. Now, don’t get me wrong, I’ve got a Meetup.com login, and I could have logged in in about 2 seconds, but this really bugged me. (As an aside, you can just go to https://www.meetup.com/find/events/ to skip being forced to log in.


Handling SMS with OpenWhisk, IBM Watson and Twilio - an Update

Permalink - Posted on 2017-07-07 16:49

Last week I blogged about a sample application I built using OpenWhisk, Twilio, and IBM Watson. The idea was - I could send a picture to a SMS number set up with Twilio, Twilio would send the data to OpenWhisk, OpenWhisk would get the picture and send it to Watson for identification, and finally the result would be sent back to the user. This morning a coworker pointed out a few issues and I found a way for the code to be much simpler.


Google Analytics and RSS Report - Version 2

Permalink - Posted on 2017-07-06 15:20

Over two years ago I blogged about a demo I had built involving RSS and Google Analytics. The reason for that demo was simple. As an active blogger, I want to have an idea about how my recent content is doing. Google Analytics, however, doesn’t have a way to recognize what my most recent content is. By combining a RSS feed and a Google Analytics API, I could create a mashup that reported exactly what I wanted - how my latest entries were doing.


Important Note for OpenWhisk Developers

Permalink - Posted on 2017-07-05 15:52

Yesterday while working on a new book (yep - I’m writing a book for OpenWhisk!) I discovered something pretty important. I generally use the OpenWhisk docs on IBM Bluemix as my reference: https://console.bluemix.net/docs/openwhisk/index.html. I knew that the docs were sourced from the GitHub repo, but what I did not know is how far behind the Bluemix docs were. This is probably just a random fluke, but it bit me in the rear (and I’ll explain why next) so I’m now updating my own bookmarks to the GitHub docs: https://github.


Designing an OpenWhisk Action for Web Action Support - Take Two

Permalink - Posted on 2017-07-03 20:25

Back a few months ago I wrote up a quick blog post on how an OpenWhisk action could support running in both “regular” mode and “Web Action” mode: Designing an OpenWhisk Action for Web Action Support. I started off that blog post with a warning stating that what I was covering was bleeding edge and likely to break. Turns out I was right - it did. I want to share a quick update to that blog post and demonstrate how it can be done now.


Handling SMS with OpenWhisk, IBM Watson, and Twilio

I have made some important corrections to this guide - please see my followup here: https://www.raymondcamden.com/2017/07/07/handling-sms-with-openwhisk-ibm-watson-and-twilio-an-update Earlier this week I got a chance to play a bit with Twilio’s API (An OpenWhisk Monitor/Alert POC) and I have to admit I was shocked at how easy it was to use. It got me thinking about what else I could do with it (as an excuse to learn of course) and I whipped up a pretty cool demo I’d like to share.


An OpenWhisk Monitor/Alert POC

Permalink - Posted on 2017-06-27 21:54

A few weeks back I posted (Monitoring OpenWhisk Activity) about how you can monitor your OpenWhisk activity. One of the things I made note of is that it would be nice to have an “alert” system such that I could specify that if a certain action began performing poorly, I could get an alert. Now “poor” is a fairly nebulous term, but today I worked on a little demo that I’d like to share.
