They arrange conferences and invite inspiring speakers with great ideas – to make our life better. They also record the talks and allow people watch & download the talks freely on their website.

I’ve known about TED for years but only some days ago I decided to watch my first TED talk (downloaded to my N900 phone to watch during the bus trip to work). Since I’ve watched around 10 talks and they’ve all been great trips to new topics and ideas!

Start with this one, Hans Rosling. Great topic, awesome visualization and he’s a fun guy to watch and listen! On the site you can download the video and also read the transcript.

Economic growth to me, as a public-health professor, is the most important thing for development, because it explains 80 percent of survival. Governance. To have a government that functions — that’s what brought California out of the misery of 1850. It was the government which made law function finally. Education, human resources are important. Health is also important, but not that much as a mean. Environment is important. Human rights is also important, but it just gets one cross.

Now what about goals? Where are we going toward? We are not interested in money. Money is not a goal. It’s the best mean, but I give it zero as a goal. Governance, well it’s fun to vote in a little thing, but it’s not a goal. And going to school, that’s not a goal, it’s a mean. Health I give two points. I mean it’s nice to be healthy — at my age especially — you can stand here, you’re healthy. And that’s good, it gets two plusses. Environment is very, very crucial. There’s nothing for the grandkid if you don’t save up. But where are the important goals? Of course, it’s human rights. Human rights is the goal, but it’s not that strong of a mean for achieving development. And culture. Culture is the most important thing, I would say, because that’s what brings joy to life. That’s the value of living.

Kurppa http://risto.kurppa.fi/blog/?p=4285 Continue reading → Related posts:]]> Time lapse photography is a method of creating films by taking a series of photos with constant interval, for example one minute, and then combining them together as a movie.

I was sick a while ago. The first day I didn’t do much but sleep and read comics. The second day, the most exciting event of the day was to see how the frost flowers in the window melted. In the morning it was about -27C but then during the day the sun heated the window so much that the frost flowers melted away. Seeing new flowers in the window the following morning, I decided to try to make a time lapse video of how they melt.

Code to control the camera

First, I grapped a piece of old camera control code from one of my old posts. gphoto2 is able to control my Nikon D70 DSLR over USB: tell it to take a shot, download the image and so on. So this is the code I ended up with:

for i in {1..400};
do
echo "#################"
echo "Photo $i"
date
echo "#################"

#capture a photo
gphoto2 --capture-image &
sleep 60
gphoto2 --get-file=$i
done

This takes a picture, waits for 60 seconds, downloads the previous picture, and starts it all over again. As it does this for 400 times, it should give me almost 7 hours of shooting time.

Notes

  • Nikon D70, on manual mode, 1/800s, F7.1, manual focus
  • Sigma F2.8 105mm macro lens
  • D70 needs to be set  to PTP mode and also had to set the camera to store on the memory card (see gphoto2 –set-config-something..)
  • Make sure you have enough space on the card! If this is a problem, you can also remove files from the camera using gphoto2 -D …
  • Make sure you start with a full battery. I did. It went empty. Tried to replace it – only to find out that also my backup battery was empty. Fail.
  • Don’t move the camera. Don’t touch it!
  • During the shooting, I had this one-liner running in the folder where the images were downloaded: while true; do gwenview -s . && sleep 300; pkill gwenview; done to see some of the images on the screen all the time. It’d be nice if gwenview would integrate new files in the slideshow folder to the running slideshow, but as this didn’t work, I needed to kill and restart it every now and then to see the latest results.

Converting JPG files to video

It sure wasn’t easy to figure out a decent way to do this. But this is how I did it:

  • Create a 3008x2000px (same as my camera resolution) jpg to use as title of the movie
  • Save 4 copies of it (title1.jpg title2.jpg etc..)
  • Create 1 second title clip: mencoder -nosound mf://*.jpeg -mf w=1504:h=1000:type=jpg:fps=8 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2160000:v4mv -o title.avi
  • Create the ‘main film’: mencoder -nosound mf://*.JPG -mf w=1504:h=1000:type=jpg:fps=8 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=2160000:v4mv -o movie.avi
  • Join these together: avimerge -o final.avi -i title.avi title.avi title.avi movie.avi title.avi title.avi

Kurppa http://risto.kurppa.fi/blog/?p=3439 Continue reading → No related posts.]]> I ordered something from proporta.com webshop. They’re nice – they let me choose one item from some options for free. I chose a 3-in-1 metal stylus to use with my Openmoko Freerunner touchscreen smartphone.

    They delivered fast, 3 days or so from UK to Finland.

    Opening the package I had a closer look of the 3-in-1 stylus. It has

    • Stylus tip – of course
    • Ball point pen – smart & useful!
    • Reset tip

    Having a reset tip in the stylus must tell something about the quality and reliability of the devices nowadays. And it’s true – every now and then you need to reset your Tomtom GPS navigator, your Nokia smartphone and so on. I do still hope that the gadgets would get a bit more reliable and not having to always carry something with you to reset the device.

    However, thanks Proporta, you’re good!
