on a recent beach stroll on the northern new south wales coast, i came across small weird-looking blue-and-white creatures with lots of appendages. having washed ashore, they looked more like unshapely blobs, but as soon as they got into a bit of water, they unfolded into a beautiful combination of shape and colour.
common names of this creature (glaucus atlanticus) are blue dragon, sea swallow or blue angel. [more...]
a few weeks ago, this outbacky-looking red dirt road led us to one of our research sites at calperum station near renmark, south australia. the namesake “21 hills” – one of these hills is ahead of us in the photo – are actually sand dunes covered lightly with mallee woodland.
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...]
