Host ID: 369

I solve IT problems. I connect system A with system B. I teach people stuff. I do this mostly with Linux systems. To make stuff happen I write a lot of custom scripts in various programming lanuages like Perl, Python, Bash, C, Java, Ruby, etc. I have clients all over the world (Australia, Switserland, US, etc).

I am also the project leader of the open source LibrePlan project. So go to that site if you need more information about an open source webbased project management application.

I occasionally write an article for my blog, but I have also written a number of books:

  • LPI Essentials (Dutch)
  • Open ICT voor Managers (Dutch)
  • LibrePlan, the missing manual (English)

If you have a question, please contact me at

Have a nice day.

hpr2706 :: Why I love the IBM AS/400 computer systems

Released on 2018-12-17 under a CC-BY-SA license.

This is a talk about my love for the IBM family of AS/400 computer systems.

Although it’s a very hacker unfriendly system there is still much to admire and love.

It’s completely different from anything else which makes it nice but also very likely to disappear in few years from now. To prevent that piece of computing history to vanish I started a small initiative called It’s just me, but it does show my intention with the system.

hpr2683 :: Using Open source tools to visualize the heartrate and blood oxygen saturation level of my stepchild

Released on 2018-11-14 under a CC-BY-SA license.

Using Python, PHP, JQuery and Linux to visualize the heartrate and blood oxygen saturation level of my stepdaughter.

Jeroen Baten talks about how he used his knowledge of a couple of open source tools to visualize the heartrate and oxygen saturation in the blood of one of his children and how this aided a pediatrician at the Wilhelmina childrens hospital to come to the right conclusion and treatment. This talk is a mix of tech and 43 surgery sessions on one single human being.

hpr2657 :: Why we are all going to shit in 30 years due to computers

Released on 2018-10-09 under a CC-BY-SA license.

Now, this is not a doom and gloom lecture.

Actually it is a talk about what is going to happen in the next 30 years.

It is a talk about what is called “postcapitalism”.

It is a talk about how almost all jobs are going to disappear due to automation. But also how we are going to think about this this and come up with solutions.

It talks about the three big challenges we need to face.

And yes, this involves you as well!

hpr2635 :: Running your own mainframe on Linux (for fun and profit)

Released on 2018-09-07 under a CC-BY-SA license.

Yes, this talk is about running your own mainframe on your own hardware. Mainframes are old, yes, but they are still very much alive. New hardware is still being developed and there are a lot of fresh jobs in this area too. A lot of mainframes run COBOL workloads. COBOL is far from a dead language. It processes an estimated 85% of all business transactions, and 5 billion lines of new COBOL code are written every year. In this session the speaker will help you in take your first steps towards running your own mainframe. If you like then after this session you can continue to build your knowledge of mainframe systems using the links provided during the talk. Come on in and learn the basics of a completely different computer system! And it will take you less than an hour to do that!
