Star X18i rooted

My novel Android Smartphone Star X18i (ordered from that particular shop), running Android 2.3.4, has been rooted using the instructions in this thread: http://forum.xda-developers.com/showthread.php?p=18615502#post8615502 (method 2b, using the zergRush exploit, v3). Nice work for the script, I just copied the instructions step-by-step. The phone itself seems to be a Sony Xperia X10 clone.

Environmental Data Mining

It just occurred to me that I should probably further develop my research profile and find an appropriate umbrella term that best covers my research interests. A quick suggestion including a definition would be Environmental Data Mining to describe the task of finding interesting, novel and potentially useful knowledge (=data mining) in georeferenced (spatial) and temporal multi-layered data sets (=environmental data). I haven’t done any research on this umbrella term yet (search engines provided but a few hits, but if I stay in research, this is probably where I’d try to be headed. Computer science is (to me) an ancillary science that needs specific applications and builds/provides solutions to specific tasks based on actual data sets collected in practice. And R is the best tool for this :-)

(this merits a new category at the top level)

Dissertation eingereicht

"Spatial Data Mining in Precision Agriculture"

 

Mit dem offiziellen Datum vom 23.11.2011 habe ich heute meine Dissertation eingereicht. Jetzt ist der Fakultätsrat dran, dann sind es die Gutachter und wenn alles glatt läuft, bin ich bei der Verteidigung dran. Vorbehaltlich der Genehmigung durch den Fakultätsrat findet die Verteidigung am 23.02.2011, 15 Uhr, in 29-301 statt. Der Dissertationstitel entspricht der Überschrift dieses Blogs.

Fürs Binden habe ich übrigens 42 EUR bezahlt. Das kann doch kein Zufall sein!

Three/Eight weeks to go

There’s a preliminary deadline for handing in my thesis. I’m not sure whether I’m going to make it, but 2011-10-19 has been set as my personal deadline, before the thesis draft goes again to my supervisor. Lots of improvements yet to do. The official one is then 2011-11-23. The site’s header has been changed to reflect the actual topic of my PhD thesis.

An Update on the MiniHomer script

Well, I updated the minihomer script described in this post. The issue was that the old script just output one GPX file describing the complete miniHomer’s log — currently around 23MB, comprising two continents. Although the GPX file is internally grouped into tracks, it’s quite cumbersome and slow to open with viking (which is not viking’s fault). Therefore, I added a few lines to use the gpxsplitter python script at the very end in the “dump” option. It simply takes the existing gpx file and outputs single files containing just one track, which is exactly what I wanted.

Here’s the script: minihomertool, version 2011-09-24

ICDM and DMA workshop in NYC next week

Just before I head off into the weekend, the latest update on where I’ll be next week:

Industrial Conference on Data Mining, taking place from Tuesday August 30th until Saturday, September 3rd, in New York City (actually, it’s near Newark Airport [EWR] in New Jersey, but it’s close enough). I’ll be presenting a continuation of my work on HACC-spatial (the hierarchical agglomerative spatially constrained clustering) which I showed at my workshop and the ICDM 2010 conference last year.

Therefore, my talks’ content will be along similar lines, with similar, but updated slides:

The second talk for my workshop will also contain a few slides about the joint paper with Antonio Mucherino, who won’t be able to come personally, but who contributed a nice survey for my 2nd Workshop on Data Mining in Agriculture.
