Amsterdam

A week ago we returned from our trip to Amsterdam. Time for the usual photo post.

I enjoyed Amsterdam (and our trips to Haarlem and Leyden) very much. We had a full week which meant that we had a lot of time. So we could really relax, sleep in and explore this beautiful city at our own pace.

One of my personal highlights was the Van Gogh museum. Their concept of showing the artist's development in chronological order in combination with works by other artists is genius. It highlights how Van Gogh was influenced others and makes you understand the paintings and their different styles so much better. Interesting, well explained and a lot of Van Gogh's masterpieces to see. Highly recommended!

Another place worth visiting is Teylers Museum in Haarlem. It's based on Pieter Teyler's 18th century collection of scientific instruments, fossils and minerals. It's the oldest museum in the Netherlands and contains all kind of cool scientific artifacts. Unfortunately not much is labeled in English. Interesting stuff but sometimes you're left in the dark about what things actually are.

Enjoy the pics.

Lollipop Lockscreen Woes

Like every other fanboy I was eagerly waiting for the newest Android release, code named “Lollipop”, to become available for my phone. Finally the OTA update arrived yesterday. So far I couldn't spot any major improvements except for a few nice animations and the new material design. But at least everything is still running smooth.

However there is one sore spot that makes me regret updating: the new lock screen.

The lock screen serves threw purposes:

  1. secure the device against unintentional button presses while in your pocket
  2. optionally secure the device contents against unauthorized access when lost or unattended
  3. provide useful information at a glance with no interaction: eg. display the current time

Unfortunately Google crippled the lock screen usefulness a lot in Lollipop.

Paper Backup (3) User Interface

This is the third and final part of the three part series describing my automatic paper backup system. After the scanner is working and we have a bunch of scripts for scanning and uploading, all that is missing is a nice user interface. That's what this part is about.

Paper Backup (2) Automation Scripts

This is the second part of a three part series describing my automatic paper backup system. In this part I explain the different automation scripts used to create a searchable PDF from a scan and upload it to the backup locations.

The setup is multi user capable. Eg. for my setup, files will be stored in either Kaddi's or my home directory on the NAS and Google Drive.

Paper Backup (1) Scanner Setup

I wrote about my Digital Backups before. But this talk by Bdale Garbee raises some good points: what happens when your house burns down? Can you prove you just had bought this Van Gogh right before the incident? What papers would your insurance need? What exactly is insured? And who actually is your insurance? Chances are that the answers to all these questions just have been burned.

So better back up that stuff. Unfortunately a lot of important data still arrives via snail mail on paper. I wanted a simple solution to archive any paper that arrives in a simple way. So I built one.

The whole system consists of a document scanner attached to a Raspberry Pi with a touchscreen and some custom software.

This is the first post of a three part series describing how I build the whole system. Part one explains the basic setup of the Raspberry, the scanner and the SANE scanner software.
