Impress Presenter Screen + awesome

edit: modkey + o moves windows between displays — that pretty much solves the whole thing. Sometimes patiently reading though a man page solves your problems more efficiently than asking Google for help. (Thanks to Wolfgang for informing me about the key binding.)

Getting LibreOffice Impress' extension presenter-screen (aka "Presenter Console") to work when using awesome turned out to be a bit tricky.
So, if youre using awesome and want to use the extension, here's how it works:

Assuming you're using a laptop with a resolution of 1366x768 and present on a beamer, connected via VGA with a resolution of 1280x960. (Use xrandr to find out the actual output and resolutions.)

1. Display setup

Your own screen: xrandr --output LVDS --mode 1366x768 --primary
The beamer: xrandr --output VGA-0 --mode 1280x960 --right-of LVDS

2. Impress

Make sure the extension is recognized: Tools -> Extension Manager
Set the presentation display to "Display 2": Slide Show -> Slide Show Settings
Place the Imress window on the beamer display and start the presentation.

You should now see the presenter screen on top of your presentation's slides, both on the beamer display.

3. awesome

With your cursor, hover over the presenter screen.
Press modkey + m (maximize window) twice.
Move the presenter screen to your laptop's display.

This all would be much easier if there was a key binding for moving (maximized) windows between displays, not only tags. I'm not aware of one.

Time-lapse photography for less than 2$

A few weeks ago I thought it would be nice to try out time-lapse photography. I searched for ways to trigger my DSLR in given inverals and found, that the plug for wired remotes was some proprietary Nikon thing and timer remotes cost 40€ upwards.

Fortunately, DSLRs can also be triggered using an infrared signal. I already owned an Nikon ML-L3, a normal IR remote compatible to my Nikon D80. So what I did (and what you can also do to have fun with IR devices) was this.

Simply connect an IR LED to an audio cable and use it to record and send IR signals. It's that easy. : )

Grid scroll

Added a "scrolling" fuctionality to the grid in the photography section — should now be at least a bit more comfortable to browse through. Writing it, however, wasn't that much of a pleasure. :D First of all things tend to end up pretty messy whenever I work on stuff "combining" PHP and JS. On top of that the "math" behind the shifting of my images went fully out of control. Loops and lists functioning in opposite directions, +1 here, -2 there — oh well ... somehow it's working now. :D
