Hedgehog Care (Egelopvang Haarlem)
From 24 Nov 2017 til 3 May 2018 we had two new hedgehogs: Henry and Joris.
Both young males. Henry (green) was brought to the Care Centre on 11 nov ’17, thin, 377 g. Joris (red) was brought 23 oct ’17, just a 156 g puppy, found under attack by magpies.
Both were still quite active the first month, walking the garden by night. Read more…
Made my own wine
2017 I did a second round of harvesting and bottling. The endresult is a bit uncertain: I may have add too much sugar to make it ripe towards a great wine. Received mixed comments ranging from “nice!” to “where’s the sink? “. Lot of bottles though, 38, twice as much as in 2016…
2016 was a splendid autumn for grapes in Holland! Read how I processed 16 bottles from two city gardens.
Bought a seawater tank!

Idea to capture identification keys
I was walking on the banks of the Allier river in the Auvergne, France, when I heard a whirring sound in the reed just next to me.
In spite of all my education and time spent in identifying animals, I had to admit i could not even tell whether this species was a kind of toad or a kind of cricket… Then it popped in my mind that it should by now, I’m talking 1998, very well possible to just grab my microphone, record the sound, and within an instance let the speaker from the laptop in my backpack tell me the right name of that creature! All in between steps are already developed in this IT era, it was just a matter of connecting it all together. An idea was born.
In the years from then on I scoped to the topic of converting from dichotomous keys to multi-acces keys, and devoted time to learn developing dynamic web pages with Oracle Apex. I realized the idea forms a nice crossroad between all my time spent in biology and all my time spent in computers. And the use of Apex confined to elements I was already familiar with: setting up data models, working with Visual Basic and Oracle PlSql programming.
