Memories from University: Teaching the Computer to play Connect Four

How do you teach a computer to play games? I took a classic brute-force approach along with some techniques to make the search for a good move faster. Can you beat the machine?

Finally my dream has come true, even though things were different than imagined: A race report of Lakes in a Day, traversing the Lake District in 50 miles with 4000 m ascent.

North of the Arctic Circle: Hiking adventures in Sweden

My dream of returning to Northern Sweden for some hiking came true this year. Streams and lakes, puddles and pools, snow and ice, mountains and valleys; orienteering, pathfinding, river crossing, wild camping. Fabulous views rewarded the efforts I put in.

Running the XNRG South Downs Devil's Challenge 2017

It’s bank holiday weekend in the UK. What better thing to do than joining a bunch of nutters for a three-day foot race from Winchester to Eastbourne, covering 156 kilometers and many hills? I could not come up with a better idea, so here is how it went.

Garden of England: Running from Ashford to Canterbury

This Saturday, I decided to explore the North Downs Way between Wye and Canterbury. A trip report touching many things: navigating with phone and compass instead of maps, public footpaths and plough teeth, explosives and barbed wire, parking lots in unexpected places, and oceans of bluebells.

Three Years in the United Kingdom: Need Candles in the Dark

Exactly three years after my arrival in London, the UK Government has triggered article 50. The Brexit drama continues, with decision-making in the dark being a defining part of the play. It is time for a few personal reflections from a “first-row seat”.

Missing Maps: Use Your Phone for the Better

The opportunities created by the advance of technology and the efforts of people are amazing. In this post, I’ll show how to take advantage and use the Mapswipe App as a first step to gain valuable insights for NGOs operating in places of the world for which there is no proper map yet.

Country to Capital 2017: Resurrection

The annual Country to Capital race takes a few hundred enthusiasts from Wendover to London Paddington in what is said to be the opener of the ultra marathon season. There are stark contrasts between country and capital, and it was interesting to observe the gradual transition.

Utility theory and pedestrian behaviour in London

A not-so-serious attempt at explaining pedestrian behaviour in London using utility theory. Ever wondered why certain pedestrians jump so readily in front of passing lorries? Ever wonder why some are keen to collide with approaching cyclists? Sorry, I don’t have the answer, either. But I am still curious. And in a mood to rant. Just a little bit.

How data can assist us in forming good habits

Habits are an important key to success. But how do we establish a habit? How do we know whether our perception aligns with reality? How do we decide about the next change to make? Did we succeed? I want to know. A reflection on habits, insights from data using running as an example.

Wendover Woods 50: First Ultramarathon

November. Saturday. Dark, foggy, chilly. These were the conditions for around 200 loopy runners to set off on a loopy five-lap course through the small, pretty & hilly Wendover Woods. 50 miles later, and after arduous 3000m of ascent, I got a fairly thorough taster lesson in ultrarunning.

Missing Maps: Putting People on the Map

There are places on our planet where people live but there is no map. How are NGOs like Médecins Sans Frontières (MSF) supposed to do field work if they don’t know where people live, how many, how to get there? The Missing Maps project is addressing the issue via crowdsourcing. I gave it a try, and here’s what I think.

Enham Alamein: Andover Trail Marathon

This weekend, I traveled down south from London to participate in the newly setup Andover Trail Marathon. The start and finish was in Enham-Alamein. A place that caught my attention – El Alamein? Historical and personal battles.

From Stockholm to Oslo by Bike

Bike touring, wild camping, ferry rides, sun bathing, bike packing, and more. A recount of a loosely planned bicycle trip that brought me another time across Sweden, and this time also a tiny bit of Norway.

The Hitchhiker's Guide to the Giants Head Marathon

On the last weekend in June, I ran (and walked) the Giants Head Marathon in West Dorset. Well-organized, welcoming, laid-back, and not so simple to get to. Highly recommended.

Without Captain, Course, Destination: Sailing Away

Several months ago, I concluded a post about the EU referendum with “Sail away. A thought abroad”. I am thoroughly disappointed that the UK actually did. Or half of it? The ship has left the harbour, without captain, without course, without destination, and most disturbingly with a deeply divided crew.

Herräng, en resa till Herräng

Några veckor kvar inför nästa resa till Sverige. Den här gången på sommaren. Vilket är ju inte den värsta tiden att åka dit. Jag är mycket nyfiken på danslägret i Herräng, vilket är välkänd bland dansarna i Swingvärlden.

Welcome to Scotland, Revisited

Back from an extraordinary hiking trip to Scotland. Soaring temperatures, not a single drop of rain, few midges, outstanding panoramas were just some of the highlights of my second multi-day hiking adventure into the West Highlands.

To run or not to run – that is not the question

At the end of last year, I had decided to spend more time outside of London to discover the rest of the UK. In order to make that happen, I booked a few races in various parts of England. Today, on the weekend of the 400th anniversary of Shakespeare’s death, this brought me to Stratford-upon-Avon.

Air Pollution – Green, Yellow, Red: Toying with CleanSpace

Got the CleanSpace tag delivered. It is a RF-powered, portable device measuring carbon monoxide concentration. I spent a few days playing with it, and sharing my first impression here. Ultimately, I want to know whether the data can help foster change to the better.

Energy from Thin Air: Measuring Air Pollution with CleanSpace

Let’s face it. Air quality in London is quite poor. You don’t need technology to notice. As soon as you reach the country side, the difference is usually very apparent. I will soon get hold of an active sensor that transfers carbon monoxide readings to my phone in real-time. Interesting: the sensor is powered only from energy harvested from wireless and broadcast networks. Energy from thin air!

Ice skating in tailwind

Great timing. A wave of cold temperature and clear skies comes to Sweden precisely when needed. But if it weren’t for the logistics, the wind could have made ice skating impossible. A story in pictures on what the dark and cold winter in Sweden had to offer.

Europe – Story of a Migrant

No, this is not a story about a refugee even though certainly many could be written. Instead, it is a story about a migrant within the European Union. A story that should make UK citizens think twice. A story against reactionary and nationalistic tendencies.

Quantify this: Running

It’s easier than ever to track your mileage in running, cycling, and many other activities. But why would one do that? For the present self to celebrate past accomplishment?. Or to post it online here for promoting one’s virtual self? No. I want to track running mileage in order to adjust my course and correlate exercise with race performance.
