Istanbul running from asia to europe


I once had a skiteacher who explained me that the advantage of skiing over snowboarding was that he had four sides (kanten) to express himself. That is how I actually feel about endurance sports as well. You have you main events to train towards, Sunday easy sets, crowded tradition runs, local village runs for all out performance and city events.

You can go faster, you can go longer, you can go for a personal best, you can go for sightseeing, or you could just go to enjoy yourself and have a great time. The other day Helen came home with an invitation for an organised trip to the Istanbul Marathon, the only marathon that starts in Asia and ends in Europe. Not really into marathoning she dismissed it initially, but somehow it got our interest. She had been to Istanbul before and knew what a great city it is. We checked the site and to our surprise a shorter distance was organised as well, with the same Asia to Europe Challenge.

Looking for great weekend out together we decided to go for it, and what a great little trip it turned out to be. Just knowing too little about Turkey other than the recent troubles I had no clue what to expect. Well, on the international business level the world is kinda flat and you do know. But other than that… Istanbul is just amazing.


What great fun it is to see the city as a runner. Instead of packing your weekend with the great landmarks and other tourist places, just center your trip around a run. Your weekend has a different rhythm because we you arrive you need to pickup your bib and startnumber. Definitely with a Marathon which has fast quantities of people visit. Needless to say all Marathon expo’s are alike, a large stadium with lots of running info and off course the place to pick up your stuff. This stadium is in the outskirts of the city, unfortunately close to the airport, so we had to travel all the way back. Luckely with a railway through the streets of Sultanahmet, so a change to see the wonderful monuments already. Going back just mesmerized by the exotic colors, sounds and smells of the markets, bazars and the great fish places near the Galata bridge

We stayed near the square and Istiklal Caddesi in Beyoglu, which is like a main, western, shoping street, only LARGER. On time to bed, we had to get up early to take the bus at 7:00 from the Taxim square to the start of the race. western To notice that Istanbul organises its streets about themes: shoe sellers in one street, tool in another, clothing in a third and so forth, like medival cities Try to see that from your hop-on, hop-off bus…. The start was exotic, chaotic, with all the local people helping out and trying to make a Lira. Somehow it feels like everybody is working hard to make some money. We got there early, so we soaked it all in and suddenly it was quiet and people started singing

A bang and off they went, Marathoners for their epic event. We had to wait half an hour longer for our start of the 10k. Running is universal and people are all alike. It just felt like any other event, only we could not understand people. Although everybody in Turkey speak English very, very well.


Half an hour later it was our time. And we started of. How funny to see that most people take the opportunity to see the bridge, walking, in opposite direction. So this was the slowest start ever. Passing it we made it from Asia to Europe, not changing our religion, btw … Only to make it worse by a steep climb the second kilometer.
But over the hill it was all down, steep and fast….. Half way we passed the Dolmabahçe Palace, the place Ataturk died and it was already time to finish the race. Over the Galata bridge near the spice market. Time doesn’t matter, we did well and it is not even a fast race with loads of walkers. We ran together and had great fun. We crossed two continents, it was time for beer.

What a great way to learn new places and see them in a different way. Next year we will be doing the same on a different run. A short distance during the Athene Marathon sounds interesting, or do you have another suggestion? And Istanbul, do not worry, we will definitly be back and spend more time on your classical attraction this time.


microsoft is open-sourcing .net

History was made today. Not only did humanity land on an astroid for the very first time, but also Microsoft re-invent (sic) itself today. Right about the moment Rosetta Philae lander touched upon 67P, news came out that Microsoft released the .Net framework into open source. This will allow it to run on Linux and OSX as well.

All the news about the great engineering feat in which a man-made object lands for the very first time, after a trip of 10 years and traveling more than 4 billion miles, was dwarfed by the news that this powerhouse of Enterprise software is moving into the 21st century. My guess is they had to do it. The days of closed end-2-end stacks is over. Teams want to be fully in control of their own stacks from hypervisor all the way up to the programming libraries.

A true confirmation of the small revolution going on in enterprise software and a great day for the world.


IRM Summit Nov 2014 Writeup

Monday 3-Nov till Wednesday 5-Nov, (Second European) Identity Relationship Management Summit ( organised by Forgerock in Dublin. Because Identity is the most important topic in the connected years to come. Forgerock invented this term, all relevant thinkers and practitioners were at the summit. I am fairly new to the topic, I found what I was looking for, amazing summit, great venue BTW. Great minds, I even so a slide with Hegel I think. Here a small writeup of what I learned.

Check the guy at second 41!

With IRM Forgerock, your 21st century startup (Series B, going solo, not for big vendor exit), moved from enterprise world (IAM:Identity and Access Management) to a consumerized world. Redefining the field while it is jumping on the Internet of Things bandwagon (I of IoT is about Identity).
In the Connected world there will be no Thing or device without a person (=identity) behind it. We will move from protecting the company wall (dmz, firewall = Hard perimeter) to protecting our data in the Cloud (think: Flickr per picture you define who can view or print your pictures = pervasive security). “the concept of Identity Management will be redefined through IoT what to own, share and use”.
First day was Partnerday and Kantara (the open initiative to propel Identity into the IRM age) workshop, Second day was customer talks, Third day was product demo day.
I did a panel discussion (together with Paul from PortBase) and a customer talk.

Numbers, Numbers, Numbers

  • “78% of consumers think it is hard to trust companies when it comes to use of their data, and 70% think there are few or no trusted ways to find out about personal data use.”
  • IAM market $6.6B in 2017 (IDC) (behind the firewall employee problem), $86B Security 2016, $8.9T internet of things 2020, $241B cloud computing 2020
    by 2020
  • 70% off all business will use of attribute based access control  (ABAC) mechanisms instead of role based access control (RBAC) (<5% today)
  • About 95% of CPU’s in mobile is from ARM (yeah Intel….)
  • Only 33% of intrusion victims are notified internally, the average attacker spends 229 days IN the network
  • Banks are still trusted 51%, Social Networks only 21% by consumers with their data (orange)

Four Topics

1. Standards

  • Identity moves to identity authorities (who is the person) and attribute (what do you know about the person) providers
  • “The password antipattern from the dark ages”, Killing passwords is IAMs new black
  • The unlisted view (youtube) is an expensive and proprietary solution and not true IRM (= define on a person to person level what to see and do)
  • Digital business changes the scope of IAM, right access for the right reasons
  • The new holy trinity: OpenID Connect, OAuth 2.0 and UMA (Unified Managed Account), old venn here
    • OAuth is about availability
    • OpenID is about single sign and federations
    • UMA, individuals and sharing Identity is about providing
  • Consent on what to do with your data
  • We will move from Role Based Access Control (RBAC) to Attribute Based Access Control (ABAC)
  • API move from CRUD to CRUDPAQ (Create, Read, Update, Delete, Patch, Action, Query)
  • is LDAP still relevant? world is moving from hierarchical to relational, path, graph, directed graph
  • Ian Glazer, the Round wheels of IAM/IRM
    • Authentication can be solved
    • Authorization not yet solved,
      • XACML is not there yet (REST/JSON is one step)
      • UMA still needs more miles on the road
    • Attributes nearly solved
      • Webscale attribute access (UserInfo, ADAP)
    • User provisioning almost solved
      • SCIM needs more supporters,it is time to adopt it

2. Scale

  • Mark Weiser 1991, The computer for the 21st century, Kevin Ashton, 1999 proposed the term IoT,
  • Functional  (mechanical scale) becomes Little data (wired scale), protect the Little data (your daily body weight figure needs your identity) before it becomes Big Data
  • CRM does think about the customer relationally not hierarchical (LDAP)
  • must be solved for all domains: web and mobile
  • Trustworthy IoT at Internet/Web scale
  • The median of size of countries is 5 million, which is not even a large Internet roll out anymore
  • The big questions:
    • “How do I roll out new services for any device or thing?”
    • “How do I scale to support hundreds of millions of users and devices?”
    • “How do I roll out identiy serviers in weeks no months?”
    • “How do I roll out services taking context into account?”

3. privacy and security

  • rights to be forgotten, eraser law california
  • Tug of War: personalized and recognized versus secure
  • In the early days your Mom picked up the phone before screaming for you: We don’t know what our kids are doing, but someone does with all the big data
  • Digital Transformation is about Digital Identity
  • Consent and Consent Receipts
  • The identity system should be able to identify threads, integrate your thread management with Identity management
  • Security will be contextual: you never login from China, but if your device (=ipad) logs in from China it is probably you
  • Protection moves from the shell (firewall, ip/port/protocol) to context and device (the ipad from person X has malware, let’s block the device and not the person)
  • bank infrastructure is (being) used for providing identity services
  • privacy and national security are like opposite of a slider (ian goldberg, nymity slider)

4. value, marketing

  • Context, context, context, context
  • personalize through context, they know more about their customer and how they interact
  • point of contact between person and thing, second point of contact between thing and service, context
  • Your coffeemachine will have an identity and you will have to authenticate yourself
    In the Digital Transformation you need one combined view of the user over all systems, on unified Identity
  • Lots of discussion about the Digital Citizen, context
  • selective/constraint person-to-person datasharing, flickr: viewing versus printing, context
  • “IRM requires the right architecture!”. We do not need more applications, but an infrastructure.
  • context, context, context, context, context. it is about you.


  • Integrated door handling combined with Identity management
  • Authenticated Coffee machine, making coffee drinking social
  • Wristbands authentication, handling and protocols
  • Connected Stethoscopes in the Internet of Things
  • OpenAM version 12 (with out of the box Google/Facebook etc integration)
  • Guardian analytics, integrated Identity and Threadmanagement
  • ENCAP, next level Online, Softtoken based 2nd factor authentication

Speakers/People to watch


  • Henk Marsman, Deloitte, Identity practise
  • Paul Saraber, Portbase Rotterdam
  • And of course, the good company of Everett!


That’s a wrap 2014

10647098_378985108919552_6588383945505144209_nIt is already 4 years ago that I started my late age sports career. Having grown to a fully sized 91kg and lot’s of complaints about my energy, it was finally time to do something about it late 2010. With great pleasure I still remember my first running training in the Flevopark, this year I finished my Half Marathon (of Amsterdam) with a IMG_1475decent 1:44:30. It was a good thing to not go farther but only faster last year. The greatest most thrilling event of the year was to finish th Kids Amsterdam City Swim with Mila!!


All in all it was a good year:

  • Running 10K – 44:45 Dorpsloop Baambrugge (was: 51:00)
  • Running 21K – 1:44:30 Half Marathon of Amsterdam (was 1:54)
  • Running 10Mi – 1:16:14 Damloop 2014 (2011 – 1:27, 2012 – 1:25, 2013 – 1:23)
  • Swimming 3 times Pampus (never mind the time, we made it ;)
  • 1/8 Triathlon – 1:10 Ter Aar (was 1:21)
  • 1/4 Triathlon – 2:26 Spijkenisse (was 2:50)
  • Weight – 71KG (was 80KG last year)

So it is time to recover and do some other stuff with the family. Some big plans and training for 2015 starts in december again.

Willy explaining planning poker

The day we visited Ashram, we had the pleasure of experiencing what goes on in the classroom. One of the classes got introduced to estimating backlog and doing planning poker. It was just the second class in the morning, first class had left the room. And we were discussing what we observed in the first class while we were waiting.

IMG_1354Some moments later a new class entered the room. Willy was a little more firm on this class, no bags on the table, but same setting, all groups joining together. This time we got some more insight; this class went through the first two lessons. This, we learned, was basically about:

  • having a short introduction in eduScrum, the basics and principles
  • dividing in groups of four based on qualities
  • breaking down their first assignment, some chapters in their class book with an end assignment

Willy continued and explained they now had to estimate the backlog, they work they had broken down the previous class into tasks with post-its. Willy distributed planning poker cards and said the first tasks, the first page of a book was 2, they had to estimate accordingly. Class looked puzzled, so he continued: “I am going to explain you something about relative comparison. I am 50 Kg,” (which I have to tell you is a little off reality), “no I am 50 Apples, no I am 50 A, how much are you?” looking at one of the girls sitting in front of the class. A little hesitant she admitted she wouldn’t know, so he asked again: “I am 50 A, how much are you?”, “40 A?”, she said. “Thank you for the compliment! but accepted, so how about you?” looking at another student. “30 A?”, she replied. “Excellent, you get the idea. Just throw away the dimensions, but if I am 50 A, you are perfectly able to estimate your are less, and you are even lesser. So let’s continue,” and he walked to a group handing them cards, taking two activities, one he declared 2 and the other was obviously more complex. “Now,” he said, “take your cards, give your estimate, and on the count of three give me your number, 1, 2, 3,…. Too slow guys, once more and all at the same moment, 1, 2, 3 ….” We saw 8,2,5, 8, 2.”Can’t be, they cannot be same as the previous task do it again, 1,2,3 ..” and 8,8,8,5,8 popped up. He declared it eight and you say some students in the other groups making sound they start to understand. He told once again the relevance of the relevant comparison, waiving away the need to be exact and stressing the importance of coming to understanding in a double blind proposal.

Some few moments later he had the impression students in all groups would understand and invited them to start estimating the complete backlog of the previous lesson. Some half hour passed, few questions, but most of all we just had time to watch and observe. And in the final minutes Willy invited everybody to add all numbers and call out the total: 250, 178, 320, 380, 290. 356, some were a little reluctant, but that would stop him.

“Now I take one of these numbers, 380, forget if it is right or not, it is the number of this group. If this is your estimation I just plot it here. We have ten lessons to go, forget about this and the previous lessons. We just take the 380, according to your estimation based on 2 for reading the first page, you need to do 380 points in 10 lessons. So 38 points per lesson (writing 38 p/l, introducing dimensional calculation at the same time again). We take the graph putting 380 on x=0 and drawing a straight line down to 0 at x=10″, basically drawing the burndown chart.

“Now next lesson you will come. It will be lesson zero and you do work. The next lesson you will come and put work from todo to done and count the numbers. It is expected you do 38 points work. That your will write done here. The next lesson you will come again doing the same. We will have two points and we know what your velocity, meaning points per lesson is.” he continued, “Now I do not care what your are doing, when you are doing it, where you are doing it. But you are expected to do 38 per lesson. If you are doing more, you are ok, having free time the last lessons. doing some french exam or something. It is up to you. If you do less however, I will ask and we will have to find a way together to go faster, ” he said, “However I do not expect you to do, since nobody ever did less”. “My experience is, ” he continued, “that first and second graders are right on the spot, eager as they are. Sixed graders however are like this, doing nothing the first two lessons and then catching on, but you will all make it on time, maybe even earlier if you just follow your own planning.”

“So it is up to you,” he said. And the buzzer went of, kids picking their bags, running of, “you just do whatever you like, but remember, ” as they went out the door, ” you listen to me and do as I tell you” and he showed a big smile because he just knows after two year, they all get it. Do their work, spent less on homework, hardly ever has to interrupt himself and they would all have higher grades.

Jeff meets Ashram

The eduScrum team is making some remarkable progress. Lot’s of classes are fully running eduScrum at the Ashram college, the first teachers are trained and applying it outside the team and even some first schools outside the Ashram are implementing eduScrum. Gradually it is growing.
So we welcomed the request from Jeff and JJ to visit the Ashram and see the results for themselves. It was a little early (school had just started for one week after the summerholidays), and the team was even a bit worried they could not show the energy and excitement that is going on in the classroom. But what a wonderful day it was. Willy and Jan prepared a great little program for Jeff and JJ to show them what they are doing.


picture copyright Ashram college, do not reprint without permission.

We arrived early in Alphen, some time before first lessons, and, boy we were allowed to visit the teachersroom, now finally we know what is going on overthere (obviously being incrowd now, we will not tell you). We stepped into the Chemistry class of Willy, with Havo 3 (15 year olds) about to start.
First thing I noticed was the classroom had the studentdesks organised in little islands of 2 by 2. So half of them with the backs against the whiteboard in front of classroom, with the back against the teacher! Furthermore everywhere there seem to be examples of scrumboards in A0 paper flaps hanging in the classroom.
The students entered classroom quietly, taking their A0 paper flaps in groups and putting them on the wall with magnets. They sat down and waited for their fellow team members to join and started discussing-working with eachother, immediately……
All that time Jeff, JJ, Jan, Willy and myself were chatting with eachother, drinking our coffee. At some point for all groups, kids stood up and shared around the A0 paper flaps, obviously starting a standup meeting. We were all flabbergasted. At some moment Willy put us out of our total confusion: he did something special, knowing that Jeff would be coming he and the class did their utmost best to do the eduScrum planning in 2 lessons, instead of three. All making sure that they would be ready before the visit, and obviously succeeded. The Scrumboards all showed backlog with broken down tasks, estimated and prioritized, a burndown chart and remarks on Definition of Done and Definition of Fun! Everybody knew what to do and just did it!
Willy had the students standup if they had previous eduScum experience and half of the class stood up. We all joined, Jeff made a little introduction and explained some of the history of Scrum. We learned that most kids really found class more enjoyable, having less need of doing homework.
Class continued and kids continued to work by themselves, not being hindered at all by five adults just standing their in the classroom. Sometimes one of the kids would standup and ask a question to Willy, but they all seem to have an excellent idea of what to do next. Just before the end of the 45 minute lesson, Willy all made them aware of the end of the class. The kids stood up moved tasks around from open to in progress or done, making pictures with their phones. Jan told me that is the way they share what to do for homework. And off they were for the next class.

We saw another class going through planning poker, which I will describe later. It was in this class that Jeff wispered to me: “This is amazing. I have seen some Scrum in schools, but that was all about having students understanding Scrum and doing some project. This is all about changing the way one teaches” and I concluded he just realized what the board of the eduScrum foundation and friends of eduScrum have noticed that something new is going on. That Jan, Willy and Ellen are really inventing some new way of teaching, together with the other teachers of the Ashram College something special is happening.


It is done! The eduScrum foundation has been founded. During the first friends meeting in March it was suggested by Rini van Solingen that it was probably best to setup a charitable foundation to support the development of eduScrum. Especially Ellen was quite keen on having this setup. Now I am proud to introduce the board:

Combined we expect to bring in loads of energy, scrum experience, do our utmost best to take away any impediment the team has in developing and sharing eduScrum, and combined we have a strong will to change the world!

IBM makes “world’s smallest” movie by filming atoms

Some mad-scientists at IBM have created the “smallest movie” in the world by moving atoms. This might seem a small feat, but just look at the first computer to sing or first computer game and you can just imagine that great things are just about to happen.

Rini van Solingen meets eduScrum

Rini van Solingen, author of “the power of scrum” has visited Willy and his classes at the Ashram College. He has written a great little blog about it as he has also seen the future.

eduScrum – the future of education

End of 2010 Schuberg Philis invited Jeff Sutherland to train everbody in Scrum. In that period we were looking at ways to structure and organize the team workload. Our servicemodel was already based on cross-functional teams, end-to-end responsible, and one of the successful approaches during busy times was to almost isolate the team in a warroom and setup a warroom list of activities. Sounds like a backlog, right? So we found out after a company visit with Anton and Harm to LinkIT. So only natural to get involved with Scrum, see if we could apply it in another context than software development. The best way to get involved is to get it from the source and get in touch with the founders and original thinkers. That is how we got in touch with Jeff.

As we moved on, one of our Scrummasters, Mark Reijn, told me that his father-in-law got interested in what he was doing and that his father-in-law started experimenting with Scrum principles in the classroom. As it turned out, Willy Wijnands and his colleague Jan van Rossum, two Chemistry teachers from the Ashram College (secondary school in Alphen aan de Rijn, Netherlands), actually found with Scrum the missing element in the new way of teaching. It was actually Mark who did a great job introducing them to the basics of Scrum and helping them setting up backlog and all for setting up Eduscrum.

Both teachers are deeply involved in renewing the Chemistry education for a long time now, looking at how to make the material more attractive from a factual way of teaching into a more contextual way of teaching. Next to that they were experimenting with how to get insight and use the personal qualities of the children in school. We had a very energetic first meeting, ideas were flowing back and forth. There is not much difference between schoolchildren and adults in business after all. And all the time I was having this one single thought: “OMG, still five years to go before my oldest daughter is going the highschool, how cool is this!”

Willy and Jan were joined by Ellen Reehorst and they started to work with other classes, everything from 12 year to 18 year olds, different subjects like Physics, Math and even the humanities like Dutch. At that point they started eduScrum and at that point a first post was written for Jeff Sutherland’s blog. What is really cool is that they are using Scrum not in a way to structure projects between teachers at school, but that they discovered the true core of the philosophy and apply in the way they teach. They had the guts to put the team central, allow the kids to select themselves based on their self identified core qualities and then have the teams sort out how to absorp the material. Instead of just grinding through the material and keep on sending as teachers, they put the team central, and allow them to find their own way. This reverse from push to pull in the classroom is resulting in more energy, happier kids and higher grades. In a world were the cognitive development of kids is key, they actually achieve more by teaching less, and learning the kids a more important lesson early on, that a team is more when you allow them to focus on their strengths instead of the individual weaknesses.

Check out the video they made, it is really heartwarming
