You’ve reached the online home of Jens Raaby, a Software Engineer at the BBC and former MSc student at the University of Copenhagen.

You can find my journal posts below. I mainly write about technological topics, with the odd foray into my other interests. The post frequency tailed off when I moved to Denmark in 2012 and I started being quite busy.

Welcome to the real world

It turns out that keeping a blog reasonably up to date is hard. Yep, I’ve fallen into my own trap.

Now running on Jekyll

After a couple of years running this site on Octopress I’ve decided to migrate all the posts over to pure Jekyll. If you see something not working, tweet me!

A very quick update

I’ve just migrated this site from Wordpress to Octopress - a static site generator. Everything seems to have moved across smoothly, but I’ve probably broken some links somewhere. If you find something broken, please leave a comment.

Master your computer: Learn to automate tedium

If you use a computer for anything repetitive (read: time-wasting) then you owe it to yourself to learn how to automate your tasks.

iPad Art

I never got round to posting these sketches I made last year when I first got my iPad. They are not masterpieces, but I can show them to people and not feel ashamed. The tools and working methods available on the iPad drawing apps are very impressive, especially with an app like Procreate where you have very advanced brush controls, layer blending and so forth.

The portable machine quandary

Almost immediately after watching the iPad 2 keynote in March 2011 I wrote a post in which I ‘reviewed’ it. I considered the benefits and drawbacks of replacing my ageing laptop with a lithe keyboard-less tablet with a clear focus on media consumption and entertainment.

Notes: Data, Context & Interaction

These are my brief notes based on a talk given by James Coplien (@jcoplien), at the Copenhagen Ruby Brigade meet up hosted by Zendesk on 19/03/2012. It was great to see a talk given by someone with so much passion and now I feel I have some idea of what DCI is.

Why no smartphone?

I have twice almost bought an iPhone. I have never almost bought any other smartphone. In fact, I haven’t bought a new phone since 2006, as I explained in an earlier post.

#7 - An older one

Today I took a few photos but nothing different enough to the earlier images. Instead I dug out a photo from July and did some editing with Snapseed, a handy but fairly limited photo editor which has Nik’s control point technology for local adjustments. The subject is a glasswinged butterfly in Chester zoo. It was a couple of weeks after I had purchased my macro lens and my first encounter with an interesting stationary insect.

#6 - Nearly there

I am back at home for the weekend, and whoever planned the tree planting around here in the 1980s certainly designed a colourful autumn show for us.

#5 - Exhausted

It was tough to think of what to do today. Fridays are always tiring and involve a rush to get things finished before the weekend, then a 3 hour trip from Hinxton to home. This image is of the last thing I see before my Friday night slumber (no, my vision is not that bad, I just thought I’d deliberately not focus so you can’t really tell what it is).

#4 - Mushroom

I really don’t like the piece I uploaded yesterday. At the time I felt like I was unlikely to think of anything more interesting to draw, so I just doodled a bit. One of the reasons for this ‘week of images’ is to force myself to create something every day. It doesn’t have to be something I think of as great, but the more time I put in, the more rewarding it is.

#3 - Abstract

Working as a programmer involves thinking at multiple levels of abstraction. You might be coding a web application, but at any one point it could be data modelling, presentational markup or low level architecture changes. Sometimes it is hard to think of something to draw or photograph. It shouldn’t have to be a real or obvious subject all the time. Therefore I just let my stylus wander and this is what came out.
