Do amazing things with a focused mind

Taking an ice bath and swimming in the Amstel river

Dec. 6, 2018
Read about my experience during the workshop I got as a birth day present involving the Wim Hof Method.

Just when the temperature was a low 2° Celsius, I jumped in the Amstel river! While it was nearly freezing outside I went for a swim, just moments after I've taken an ice bath! This post is about the incredible birthday present I got, a workshop involving the Wim Hof Method.

Rescuing files from a broken harddisk

Make backups to be safe rather than sorry!

Oct. 16, 2018
Yesterday I helped a young woman with her broken computer containing precious photos, could I safe them?

Yesterday a young woman brought me her laptop, it didn't start anymore and it only showed an error message. It turned out to be a broken harddisk. It startled her when I told her that all data on the disk was lost. She told me it contained precious photos of her pregnancy and young child. What could I do?

Helping people with free software

Installing Debian GNU/Linux on an old laptop

July 20, 2018
This week I helped a man with repairing and reinstalling his computer with Debian GNU/Linux.

This week a man brought his laptop to the community centre where I help people with computer problems as volunteer. The old laptop wouldn't start anymore and had to be reinstalled. Instead of Windows, I installed a free operating system. I think it is important to tell you how and why I did it.

Enjoy a festival without alcohol

Alcohol-free beer at Rock Werchter

July 10, 2018
This year I didn't drink alcohol during Rock Werchter, leading to interesting observations during the music festival.

Last weekend me and my brother went to Rock Werchter, a multi-day, music festival in Belgium. Over 140 thousand visitors enjoy world famous artists like Pearl Jam, Nick Cave, Artic Monkeys, Noel Gallagher, The Killers and the Queens of the Stone Age. This year I didn't drink alcohol during the festival, leading to some interesting observations...

Outside the comfort zone: amateur acting

Wearing an heart rate monitor during my debut performance

Apr. 18, 2018
This month I strapped myself with sensors during a little experiment outside my comfort zone: I debuted as amateur actor!

This month I made my debut as amateur actor. I am no Hollywood star, nor do I envy to become one. But I do like crazy experiments and operating outside of my comfort zone often leads to new and refreshing insights. I took part in an amateur drama play and - in the name of science and fun - strapped myself with sensors to measure what happened to my body.

Something the smartwatch will never have: patina

Wear and tear by the hands of time

Jan. 21, 2018
Patina is often neglected when comparing smartwatches with regular watches.

A good friend of mine had an issue with his Apple Watch, the digital crown lost a rubber ring causing the watch to lose its water resistance. Apple made no problem of it and offered to replace his "device". While it solved his problem, it felt painful to my watch lover's ears. It made me realise the one thing a smartwatch will never have: patina.

Lessons from a takeaway plastic bag

My ever increasing antipathy to planned obsolescence

Jan. 8, 2018
How we're tricked into repeated purchases replacing perfectly fine products just for the sake of change.

About five months ago I got some take away food from our local Asian restaurant. They packaged the food and gave me a plastic bag to carry it home. On my way home I was thinking about the bag. Although it has some nice styling printed on it, it's designed for single use only. What a waste... making me wonder: how long would it last if you would use it on a daily basis?

Commuting by bike

One week (240KM) on the VanMoof Electrified S

Dec. 2, 2017
One week on the VanMoof Electrified S E-bike testing it for commuting and comparing it to a normal bike.

For a few years now, I commute to work using a bicycle. I have lost more than 15KG since I stopped using my scooter. This week I tested a VanMoof Electrified S, an electric bike with an industrial, minimal design. Is it any good? How does it compare to a normal bike? Will an electric bike make you lazy? Read along to find out!

Climbing Mount Etna

Visiting an active volcano on Sicily, Italy

Sep. 2, 2017
Climbing Mount Etna, an active volcano on Sicily Italy.

Last week me and my wife went to Sicily for a little summer holiday. It is the largest island in the Mediterranean Sea. It is an autonomous region of Italy, along with surrounding minor islands. It's home to Europe's largest active volcano: Mount Etna. We had a chance to visit this lava spurring monstrosity and it was quite the experience.

Fietselfstedentocht 2017

Cycling the 235KM bicycle tour through Friesland

June 30, 2017
Cycling the 235KM long Fietselfstedentocht through Friesland

This month I cycled the Fietselfstedentocht, a 235KM tour through Friesland. This tour brings you through various Frisian cities throughout one of the most Northern provinces of the Netherlands. The tour was first organised in 1912 and has grown to become legendary due to its history, challenge and popularity; well worthy of a blog post!

Being a volunteer in Amsterdam-Zuidoost

Computer support in the local community center

Nov. 21, 2016
About my work as volunteer in the local community center in Amsterdam Zuidoost

After realising how lucky I am as an healthy, well educated, young man with a solid income, I wanted to do something for other people as volunteer. It just so happens to be that two years ago I received a flyer in my mailbox from the local community center: they were looking for someone with some knowledge of computers. A very interesting journey was about to begin!

Cash is king, or is it?

The wallet- and cash-less experiment

July 15, 2016
Is the time right to ditch the wallet?

Very often I see men carry a wallet filled with plastic: multiple debit and credit cards plus a bunch of loyalty programs and membership cards. Then, some even top it off with stinky paper money and sticky metal coins! It made me wonder if I can free up one pocket by ditching the wallet?
