Barrier troops

I’ve been rereading the awesome ReInventing Organizations by Fredric Laloux. The first chapter in particular is awesome. It’s a history the evolution of organizations through history. What I like about it is that it highlights both the strength and weakness of each new stage of organizations.

As I was reading about Amber-Conformist organizations (think strict hierarchical, big organizations) I had train of thought that I wanted to share, as I’ve during the last two years experienced much of those types of organizations myself.

My point here is that I’ve also seen residues of this kind of behavior in modern organizations. I think it can be useful to notice it and do something about it before it gets… nasty as we soon will see.

Speed up Jekyll site regeneration

I’m a happy Jekyll user since about 1 year ago. Really nice experience so far and the auto-hosting on GitHub is just an added bonus that lifts the joy a little more.

The only thing is that I have 1017 posts on this blog. When I write the posts, locally, Jekyll rerenders all of them. That takes up to 50 seconds.

I feel the need. The need for more speed.

Using the scientific method on our board

For quite some time I have been working with the management team of Rumah Sakit Bungsu in Bandung. It’s been quite a journey and I’ve learned a lot from doing so.

The last couple of months we have been trying a new approach to get better control in what we do and faster feedback on our actions. A couple of days ago it took flight and the director of the hospital just got it. It was so rewarding to see and hear in action.

In this post I wanted to present the way we are working. Right now I might add. Hopefully we do something else in the future.

Way in the bottom of this post you’ll find an summary should you find it long to read.

Me and my kidneys

Instead of posting this longish description in the social medias I thought I’d write it up here. That way it’s easier to refer people here instead.

Ordinary and casual readers of my blog, sorry. I’ll be right back with normal content in a few weeks. Thinking about doing a new series about writing a NuGet package in DNX-land, using my Mac…


I’m in hospital. Again. From the same kidney infection since the last 3 weeks. I’m better this time but it’s a little bit serious and I need antibiotics twice a day for seven days.

How did this happen?

Most likely I have passed a small kidney stone or crystal. Doing so damaged my urine bladder and … piping (Yeah, I know these terms well. NOT!). At that same point I have got some bacteria that traveled to my kidneys.

How do you feel now?

I’m not too bad. Since I’ve been eating (broad spectra) antibiotics and pain killers all this time many of the symptoms are very weak. I’m tired and weak and some pain in the kidneys.

Are you ok with everything practical?

Yes. The only tricky part was the last 24 hours. That sorted. I’m in a good hospital and well treated.

We will be fine.

Making dynamic chart in Excel

It was quite some time since I wrote a How-to-post. Here’s an Excel-thing that I managed to solve today that’s been bothering me for a long time.

Here’s the scenario:

  • We have plenty of data point, one per day, counting something (really the number of patients per day but it can be anything). This is displayed in a diagram like the one above.
  • After 2 months this starts to get out of hand looking at and really we’re only interested in the last 30 days
  • Sometimes though it could be fun to see more data in one view

Basically we want the diagram to dynamically show the last 30 days (or any other number of days we fancy). Like a 30-day window backwards.

This post describes how to do that.

DISCLAIMER I have, for some stupid reason, a Swedish Excel installed. I have translated the formulas but some other names (like menus etc) might be off. Please bear with me.

New PluralSight course: npm as a build tool

I’ve just (October 21 2015) got news that my latest course for PluralSight is published.

Find it here.

This time I took the opportunity to put together a course on using npm (Node Package Manager) as a build tool. I think it makes for a very lightweight and flexible option for any JavaScript (or front-end heavy btw) project.

As you might know I’ve written a couple of posts on the topic:

Review: #NoEstimates - the book

The #NoEstimates movement have lived a turbulent life on twitter. I guess that happens when you present ideas that challenges how we, as a collective, view the world today.

What’s funny is that after awhile, when the dust settles, it seems so natural and you ask yourself; “well, what was the fuzz about”. This is when the idea has got traction and maybe some of the early rough edges has been rubbed off.

My friend Tobbe puts it nicely;

One of those moments I think is when someone decides to write something (substantial) down to present compelling, practical, solutions to some of the discussions that’s been had so far.

The NoEstimates book is just this; a set of tools pointing towards another way of doing software development.

The metric / visualization pirate 'rules'

At my current client, the hospital RS Bungsu in Bandung, we are working a lot with metrics and visualizations. This has proven to have a profound effect in interest, focus and understanding for the entire staff.

During the last years a couple of “rules” (I’ll come back to the quote marks soon) has established itself. Based on our experience and feedback we have come up with a few guidelines that helps us to do better metrics and visualizations of them.

In this post I wanted to share our current set of “rules”. Hopefully this will be helpful to you and maybe even you can share your guidelines with me.

“This works for us” (™), “Your millage might vary” (™) and “Please see past the practice and look for principle that you might find useful in your setting” (™). All of those applies to this post.

How trust, kanban and a little structure changed a life today

I’ve seen many people change into something better over my years as a consultant. It’s beautiful thing - but I’ve never experienced something like that I witnessed today.

I was a small, small part of that change and I wanted to share the story with you. It’s a powerful testament to what capabilities lives in each human being that can be released if given the right circumstance and rooms.

Changes - reasons or the opposite

This is just a short post on a (in the western world) well-known topic. I think I read it first in Switch

People doesn't oppose change. People opposed being changed

Or maybe with more details, if you make a change without a compelling reason for doing so the change management will be uphill from day one.

I’ve mostly been the changer in this, but recently I was the person being changed (the changee?) and I wanted to share my experience and thoughts. So that I, at least, never ever does this again.

EADDRINUSE when watching tests with mocha and supertest

You are happy to meet me among the living. The error I’m describing nearly killed me with frustration, and if that didn’t happen I was about to help it by finish myself off.

No worries though - I found the solution. Hence I’m alive and can tell the story.

This is the error, that haunted me into the wee hours of the night, in all it’s glory:

1)  Uncaught error outside test suite:
 Uncaught Error: listen EADDRINUSE :::3000
  at Object.exports._errnoException (util.js:837:11)
  at exports._exceptionWithHostPort (util.js:860:20)
  at Server._listen2 (net.js:1231:14)
  at listen (net.js:1267:10)
  at Server.listen (net.js:1363:5)

  at Object.<anonymous> (test/site.spec.js:1:73)
  at Array.forEach (native)
  at StatWatcher._handle.onchange (fs.js:1285:10)

I got that error from mocha when watching my tests with the --watch flag. But only when I ran that watching command as a npm script from package.json. Yeah, it was pretty complex to sort it.

Requiring the os - runtime-js

This is my second attempt to write this post. It’s not that the post itself is hard to write but the concept makes my head … go ouchie. That tend to happen to my head when I see potential quantum leaps.

Instead of the fancy intro I had planned, I’m just going to give a short introduction, point you to an awesome article, tell you how to get this to run.

So what is it then? Basically runtimejs is a tiny, unikernel OS that you can bundle together with your application, as a dependency to your application. Which is basically what a OS is, right? Our application needs some libraries like koa, a runtime-platform (like Node) and an OS (like Linux) that the platform can run.

What if that last part just was a dependency like normal to our application? Like this:

"dependencies": {
    "a_small_little_os_just_for_me": "latests"

That would be so cool. Let me show to get that to work for a Koa application

The forced swing in my garden... and coaching

The other week we put up a thick rope to use as a liana, al á Trazan, for our kids. Extremely simple; just a rope, and I made a big tangled knot at the end. You can see my kids use it on the picture to the left. They loved it.

Then one day one of our neighbors, that often help us and stops by - nice people, came by. He looked that the rope, saw my kids struggling to climb it and said:

you know... it should really have a plank or something at the end so it's easier for them to stand on.

I said: Nah… this is good enough for them. They are enjoying themselves plenty.

Two days later …

This is a post on coaching, asking before helping and not improving things that works fine.

The Lars-principle

Today I had a session with the management group of one of our hospitals. We ended up talking about how to choose what we’re going to do next. Questions like; “but how can we know what is best”, “there’s so many things to do” or “everyone have a different opinion” were discussed during and after the meeting.

I was reminded of a tip from a colleague and (to me) mentor from way back, Lars Littorin. I was complaining about so many things to do, not knowing where to start etc. His answer:

Great! Then you know exactly what to do; make a list of the things you need to do, and then start doing one of them.

There’s much truth in there. I think Lars is a great guy, but I doubt he knew how much use I have had from this single quote. Maybe, just maybe, he doesn’t even remember saying this to poor confused soul from way back

I dedicate this post to Lars, who helped me so much in the early stages of my consultancy. We worked daily and very closely between 2000 and 2005 ca.

Review: Nature by Ron Jeffries

Got a recommendation to read Nature by Ron Jeffries and I did. What a read! I loved it from the get go.

My short review is quite simply;

“This book made me think. It left me with more questions than I had going in. But better more concrete questions. Seeking simple(r) answers. Also it’s sprinkled with challenges and gentle provocations of the current state of mind and process.

The underlying principle ‘Simplify it’ is something that resonate very deeply with me. I recommend anyone doing, struggling to do or thinking about doing this thing we call ‘agile’ to read this book.

And then give a copy to every important person in your organization.

Thank you for a great read!”

Indicators; leading, trailing - short or long

This is a just a short post, mainly an idea that I can get out of my head.

I’ve been helping the management team at one of our hospitals to come up with something to track our progress against. The main question was actually quite simple:

How would we know if this hospital is awesome?

We came up with a couple of balancing scores that we will take for a spin in our first experiment round. The idea is the these values will guide our actions - if we can make things that improve the values (one or more) it’s a good thing. In the spirit of balancing scores we are keeping track on more than one to make sure that we’re not tilting our efforts toward, say only financial values.

Hmmm… need to write some of those ideas down, maybe. Ok - now to the topic of this post:

In talking about the targets we mentioned leading and trailing indicators, the difference between them and I had a little personal revolution about the difference and usefulness of both kinds.

What can you do for us then?

A couple of days ago I offered my services to one of the hospital directors here. In their current situation they could need some structuring and focus on start executing. I know that I can help them with this (using my normal “tricks” of visualization, transparency and short iterations etc) and hence asked if I could be of assistance.

Now, this particular director is a really smart one and the response was quick, to the point and a real head twister for me:

Thanks for that offer! What is you can help us with, then?

I was a stumped! What do I do? Why would anyone want that? Who am I to think that I can help them? I’m an IT guy, no formal training, no formal authority here. Why should they want me?

I ended up referring to my past work and try to describe that to the director but I couldn’t get the thought out of my head.

Yeah, this is one of those “Marcus thinks out loud post” on coaching.

Experiment - don't change

I re-read a post I wrote about 6 months ago, after a consultancy gig at Nintex. And one thing in there resounded with me and some of the conversations I’ve been having lately.

I wrote (and said):

Stop changing and start experimenting

This would probably be my #1 tip for change management; don’t do changes - do experiments instead.

In this post I thought I’d examine that recommendation in a little more detail.

The 1000th post

Just ran a my count script into the _posts directory of my Jekyll installation. 999! and then I started this post.

That means that this is the 1000th post on my blog!

I only have 3 words: Un. Believe. Able.

I never, ever thought that I would write 1000 posts.

Through this blog I’ve learned so much, connected with so many people and got so many opporunities I never would have got without “throwing myself out there”.

This post has two parts: history and stats.

Wash your hands - make your hands clean

We’re ready to sit down to eat. The kids comes running and I do the regular check-up: Nope - all hands, some of the faces covered in dirt. Me:

Wash your hands!

The run off, remarkably without complaining. 15 seconds all three of them are back. Hands, faces and much of the shirts are dripping with water. Hands and faces are still dirty.

This is my fault. I was really just focusing on the activity rather than the outcome. I see this sickness in myself, many organizations and even our community at large.

In this post I wanted to examine this thought a little closer. I have no idea where I might end up, but I’ll type on for awhile and then structure it into something worth reading… or you’ll never read this
