here are two customized picasa buttons to automate things that i’ve done manually for far too long. i’m publishing these mostly so i’ll find them in the future myself, but they may also help others looking for a way to do something similar.
sortfiletypes moves all raw files (.arw) and video files (.avi, .mp4, .thm) of the current directory into their own subdirectories, respectively, and deletes .lrv low-res video preview files.
syncraw compares the .jpg and .arw files in the current directory and moves raw files where the corresponding jpg file has been removed to a new subdirectory “deleteraw”, so you can easily delete or move them. [more...]
here’s of time-lapse of thunderstorm clouds rolling in over the calperum mallee, south australia. at less than 250 mm mean annual rainfall, every drop of rain counts. this short rainfall burst brought 7 mm of rain.
recorded with a brinno tlc200 pro at 20 s interval.
i’ve always been fascinated by bioluminescent phenomena. in a relatively wide range of organisms, evolution at some point produced species that can produce light, from marine plankton in warm seas, to fireflies, to the famous deep sea anglerfish.
lesser known is the fact that damp wood can also give off a very faint glow in the forest at night. the bioluminescence in this case is produced by fungi, whose mycelium as well as fruiting bodies glow faintly. it is believed that this helps attract insects that will disperse their spores.
a recent research trip to the daintree rainforest in far north queensland, australia, gave me a first opportunity to see bioluminescent fungi. [more...]
here’s a “tiny plot” render of a photosphere (android’s take on 360 degree panoramas) recorded in the conservatory at the royal tasmaian botanical gardens, hobart:
when you factory reset your android phone or switch to a new smartphone, there is unfortunately no easy way to transfer your existing viber messages, received files etc. if you’ve got your mind set to it, there is an manual to migrate viber. the downside of this manual is that upon fresh setup of your android phone, your android contacts may change device-internal IDs, which are used to connect viber contacts with your phone contacts. as a result, messages and threads may be randomly assigned to other contacts in your address book, even if they don’t have viber accounts.
here’s how to manually fix the problem and correct contact names in viber: [more...]
it’s been rather quiet in the blog lately, so i thought i’d share a peek into what we’ve been up to at work:
Hydraulic vulnerability analysis using X-ray microCT
One of the major points of critique for hydraulic measurements of xylem vulnerability and embolism is that they are destructive measurements. In contrast, non-invasive imaging has made it possible to observe xylem function and the spread of embolism in living, intact plants without destructive sampling and associated artefacts.
In collaboration with Iain Young and Richard Flavel at the University of New England, Armidale, we recently scanned the stems of young Eucalyptus trees at high resolution using X-ray Micro Computed Tomography (microCT) to visualize the loss of hydraulic function at increasing levels of drought.

with the dramatic clouds and colours at sunset today, a panorama was just waiting to be recorded:
