Part 1 of: one button scan to dropbox with your #raspberry pi

My tinkerTable works as a document management system... kind of.
That's why there's a button which starts the scanner and saves the scan to dropbox.

Here's what you need for the scanning part:

sane
make sure your scanner is supported:
http://www.sane-project.org/sane-mfgs.html

Install sane:
    sudo apt-get update
    sudo apt-get install sane
allow user to scan:
    usermod -a pi -G scanner
this didn't work with the raspberry pi model b, but scanning worked anyhow.

check scanning:
    scanimage -L

this didn't work, but I got a result using
    scanimage > test.ppm

imagemagic is needed to convert images:
    sudo apt-get install imagemagick

I've found lot's of help here:

How To prevent your pi's screen from going to sleep

If you don't want your screen to shut down try this:

sudo nano /etc/kbd/config

edit these two lines:

BLANK_TIME=0
POWERDOWN_TIME=0

and then, if you realize that this didn't work, try:

sudo nano /etc/lightdm/lightdm.conf

in the section [SeatDefault] insert this line:

xserver-command=X -s 0 dpms

(And: How To prevent yourself from going to sleep: ssh into your pi)

But I still love to take my Stevens out into the woods. It takes me to work every day, we had fun going to The Hague together and I enjoyed even the sometimes painful ride to Copenhagen.

Market Research: Shoes & Footwear - Results & Findings

It was time to get me a pair of new shoes. As always it was a long process to find the best solution. First there are my own needs. My personal list of problems my shoes have to solve in their life is the basis. Then a thorough market research has to be made. There are thousands if not  millions  of models  and types of shoes which have to be taken into account here! And then there are blue Vans Sk8-High...

38.224 lines of Music as txt

I like to listen to music and I like to track everything. That's why I now have 38.224 lines in a txt file representing the music I listened to over the last 22 month and it's also why most of my friends think I'm kind of weird.

Here's how:
The basic is Spotify as my streaming music service of choice. Spotify allows you to scrobble all the music you've listened to over to last.fm. You'll find that somewhere in your spotify settings.
Now to collect all this data for myself, to play around with it and get happy, I needed my own list. Using an IFTTT recipe, everytime a new 'scrobble' was made at last.fm, a line was added to a google spreadsheet. Unfortunately google somehow added a new file every 2000 lines so that I decided today to tinker all those files into one txt file and to change the IFTTT recipe to dropbox (Here's the recipe). While I'm writing this, the recipe creates a second file in dropbox too...

Here's what:
Having all those lines of pure music data as a txt file, you can easily import it into your spreadsheed.
Using a little pivot table I found out that I've been listening to 2212 different artists, Alt-J at first place, followed by Turbostaat:

My most-played song over the last 22 month was All Opportunities by Solander.
I didn't even realize that It's On is a song of both Broncho and Pins:

What I double checked is this chart: it shows songs played per day. And there are days when I listened to more than 200 songs:

By hour of day:

Now I could cluster artists by hour... or day of week ... or I could go outside, enjoy the sun, have some coffee ...

Sorting my apps...

So the first train was late and I missed the next connection. Made the most out of it and color sorted all the apps.
