Delayed responses with AWS Lambda and Claudia (Pingu part II)

Before the summer I showed you how to build a Slack bot using Claudia - it’s a very simple ping command that you could run from a Slack-client. However that implementation had a flaw; if the command takes more than 3 seconds to complete it fails.

This has to do with a restriction in Slack that doesn’t allow requests to take more than 3 seconds. In my mind created a super complex and beautiful solution including me handing a message of to a queue and that I then polled and called back to… I ran out of time figuring out.

Which turned out to be a great thing, since the Claudia team not only created a new beautiful site https://claudiajs.com/ but also wrote a tutorial on this exact topic

In this post I will re-implement pingu using a delayed response as in that tutorial.

Some reflections after seeing mob programming in action

Since the first time I heard the term mob programming it has intrigued me. I love things that challenges me and me perceptions.

The idea behind mob programming is deceptively simple and yet powerful: have all the team member (3-5 seems most common) working together on one keyboard, one computer and one feature at the time. Or as Woody more eloquently puts it:

All the brilliant people in the same room working at the same problem at the same time

What struck me is that this simple idea solves many problems that I often see teams struggle with.

I’ve written before but never been full time member in a mob. However just before the summer I saw two excellent examples in action, and I have number of friends that have been full time members of a mob for more than a year. My interest with...

The Bungsu Story - some progress

About six months ago I got home from the adventure of our life time in Indonesia. At the time I was actually feeling very underwhelmed and that we’ve failed in our work there.

But the more I think about it and the more I speak and write about our experiences there, and especially the mind blowing transformation we led in Rumah Sakit Bungsu - the more I realize that this is an once in a life time thing that have happened.

I’m writing a book about that journey. with my good friends at Oikosofy. But I have also given a few presentations on the topic.

This post is just an update about the progress of the work around the “Salvation Army hospital that rose again” that I’m calling it.

Building a Slack command with Claudia bot builder

I’ve written a few posts on Claudia now and as often I jumped almost too early on the boat - it turns out that there’s significant improvements to both Claudia herself and the entire ecosystem around the main tool.

The main tool Claudia:

automates and simplifies deployment workflows and error prone tasks, so you can focus on important problems and not have to worry about AWS service workflows

In this post I wanted to check out a new tool around Claudia that helps you to build bots for use in chats - specifically for this post in Slack.

AWS Lambda is really cool but it leaves one of those: Oh wow… now what am I going to use this for? feeling. It’s just code that scale infinity without you having to worry about it. It’s a very open playing field.

Jidoka - an old Toyota practice makes an guest appearance

When I started to learn about lean I naturally heard a lot of Toyota stories - it’s pretty inevitable since the whole thinking comes from there. One thing that I learned about was translated as autonomation. I was pretty sure it was a mistranslation.

But the other week when one of my team members said:

What’s the big deal of many things going on? If I’m blocked on a few items I can equally well just start a few more.

(Not his exact words but still those lines of reasoning)

At that point I saw the time to implement some jidoka (as automation is called in Japanese) in our project

A scary thought experiment

Just a short post on a little thought experiment I’ve been testing out.

I am right now in a big company trying to apply agile and lean practices for software development. We struggle because we meet the current organization that is not built to move in the way we want it to.

… and now everyone wonders why things take so long and we are not getting more through the system.

Solving the underpants gnomes pitfall

I have a problem; I often have a hard time connecting our vision and overarching goals to the items that we are actually working on. I want to be able to pick up anything we do and understand why we are doing this now and how it will take us closer to our goal.

I’ve blogged about this before and in my time in Indonesia I even thought I had a great way of uncovering what those high-flying goals really means, by simply asking this question:

What can we measure to see progress to that goal?

But it turns out, understandably once I think about it, that question is too hard. The gap between the vision and the work is quite simply too big.

To me often the connection between vision and our work reminds me a lot of the business of the underpants gnomes in South...

Requirements are not problem/opportunity descriptions

A few weeks back a team mate, developer and agile dude extraordinaire, said something profound:

I’m used to people coming to me with problems they need solved. Not solutions.

It was in a backlog grooming meeting and we were discussing if the item was ready for the development team to start to work on or not. It was. Well and ready. But the people writing the requirements felt that it was not worked through enough.

At the time I just giggled a little about this but it got me thinking and herein lies the heart in how the work with a backlog changes when you start to “do agile” or work in shorter releases.
