Coffee degrades over time. Depending on the surface area it will degrade faster. Therefore coffee grounds should be stored in airtight containers. Still, they go stale in days. This process speeds up under conditions of high temperature, light, or high humidity.

So, what do you do when you go on vacation and forgot clips or other things at home (like I typically do...)? As you can see on the little picture, I use a fork. It looks funny but does the trick. And I also try to buy half pound packages so that I use the coffee ground more quickly.

Of course, the quality of the resulting coffee is still not getting to close to what a Jura can produce, but it normally suffices for me...

<![CDATA[Thinking at ease]]>http://goehlmann.info/blog/2013/09/Thinking-at-ease The Thinker

Last Wednesday I participated in a course on the basic principles of the Thinking Environment. This concept has been developed by Nancy Kline. I tend to be skeptical when people come up with impressive sounding names for concepts ("Thinking Pair", "Time To Think", ...), but I was happy to hear that the people running the course stressed the practicality of the course. A key sentence in their introduction was that they wanted to help participants to see that many things we consider "common sense" are actually not "common practice".

Of course, it is difficult to summarize the course in a few sentences. However, there are a small number of items that I find interesting to consider and which I plan to explore in my team meetings over the coming months, for example:
• Formulate agenda items as questions - this should trigger more thinking (and active participation) than bullet points.
• Go around the table with no interruption so that people have equal opportunity to speak - those who are fastest to interrupt do not necessarily have the best ideas.

While reflecting on the course, one other thought came to my mind: I wish that those "courses" would be given less frequently, but that people with useful insights would rather be invited to utilize/apply their approaches in real meetings/situations. I am convinced that this will have a more lasting impact than attending a course - no matter how good it is. Which closes the circle to "common practice" vs. "common sense".

<![CDATA[Playing at Guus Meeuwis concerts in Eindhoven]]>http://goehlmann.info/blog/2013/07/Playing-at-Guus-Meeuwis-concerts-in-Eindhoven Guus Meeuwis

Last month I have played together with our music group TOG Engelen and marching band Cornu Copiae from Waalwijk at the concerts of the well known Dutch singer Guus Meeuwis. As he is singing primarily in Dutch, he is very famous in The Netherlands but less popular in other countries. Still, he manages since a number of years to draw tens of thousands of people each year to his major concerts which he calls "Groots met een zachte G". The title of the concert makes a reference to the fact that - even though people frequently think about Dutch people pronouncing the "G" very strongly - the southern part of The Netherlands prounces the "G" more softly - similar to the way the Flemish (= Dutch-speaking) people of Belgium do.

During his last concerts (Fr, Sat, Sun of June 7-9), the one millionth visitor came - a very special achievement for Guus Meeuwis - for whom he wrote the song "Lach van een millioen" ("Smile of one million"). While our part was primarily to underline the show element of the song rather than to contribute to the musical quality, it was great fun - certainly something very different to my normal routine as a scientist in pharmaceutical research...

What remains for me beyond my pictures and memories of these concerts (3x about 35 000 visitors at the PSV stadium in Eindhoven) was the positive impression the people coming to these concerts made. I find it quite extraordinary how people of different ages came together and really had a good time. I am really impressed.

<![CDATA[Errors when installing lme4 for R version 2.15.0]]>http://goehlmann.info/blog/2012/06/Errors-when-installing-lme4-for-R-version-2150 R

I have just moved to R 2.15.0 and needed to make use of the R package lme4. This kept failing for me with the following message:

/usr/bin/ld: cannot find -llapack

Initially I tried various ways of loading lme4 from R-forge, CRAN, ..., but eventually I stumbled over the comment that I may have the run-time, but not the development packages. So installing those via

sudo apt-get install r-base-dev

did the trick. Now lme4 works!

<![CDATA[Amateur Radio]]>http://goehlmann.info/blog/2012/01/Amateur-Radio PB3RXV

After about twenty years of being busy with other things and not having the money for a hobby I very much enjoyed, I am now taking small steps to see whether amateur radio is still fun. I am optimistic with all the technological possibilities that were created the past years. Certainly the concept of EchoLink looks very interesting.

As I am not sure about the amount of time I will have, I felt it would not be wise to spend a lot of money. I have just ordered a KG-UV6D from Wouxun. It is dual-band (144-146 / 430-440 MHz), has a modern Li-Ion battery pack and seems to get some good reviews.

So, in the highly unlikely case that you share both an interest for molecular biology / genomics and amateur radio, my Dutch call sign (after handing in my German license) is PB3RXV.
