blue dragon: a beautiful bad-ass nudibranch

[posted: ]  [0 comments]

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.

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.

picasa buttons: automatically sort video and raw files into subdirectories, delete orphaned raw files

[posted: ]  [0 comments]

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.

after: three new subdirectories are created and filled according to the criteria mentioned above.

(picasa buttons: automatically sort video and raw files into subdirectories, delete orphaned raw files)

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...]

bioluminescent fungi in a tropical rainforest

[posted: ]  [0 comments]

bioluminescent fungi at cape tribulation, daintree rainforest 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...]

how to fix contact names in viber after data transfer or restore

[posted: ]  [0 comments]

how to fix contact names in viber after data transfer or restore 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...]
