33C3 - Day 4

#33C3 at the Hamburg Congress Center

Puh, it's almost over. Day 4 and I'm exhausted.

There have been a lot of things going on. Very interesting talks and people, small games and projects and a huge amount of new impressions. I came here with the goal to inspire my passion about the constructive usage of technology for any purposes - and have found no disappointment in that sense 🙂

I've loads of Pictures still to process and hope I will find some time during my flights.

A very amusing suggestion is Konfusius' talk about Hebocon. That was a funny one.

So in the spirit of the 33C3 - Be excellent to each other. And have a great new year!

33C3 - Day 2

Good morning Hamburg! It's 10:00 in the morning an I am walking through the Apothekergarten towards the Congress Center. It's quiet on the streets.
In this moment I realize, that it's the time after Christmas. It's winter. It's the time of the year, where a lot of people took holidays to recover from the year, to reflect about all the things that have happened and that are going on. It's a time of peace.

Be excellent to each other!

I'm here at the 33C3 - The 33rd Chaos Communication Congress. It's awesome! 🙂

People here are very friendly. Due to general "Verpeiltheit" I've forgotten my Lenovo power supply unit. Also the nearby Saturn has none of those on stock (that's a shame! You have a Lenovo section but such crucial elements not on stock?!?)
Fortunately, since it's quite common I always find a way to charge it - From a huge power back with a lot of special adapters to some friendly people who borrow me their supply.
Lesson learned: If possible, always prefer a device that is quite common, so you can borrow equipment to and from other people.


There are still a lot of things going on. Stay tuned and remember: Be excellent to each other 🙂

Greetings from 33C3!

Greetings from the 33C3 from Hamurg! Here you get a Screenshot of the current internet conditions here. Awesome!

Internet on the Congress

Currently there are a lot of things to discover, and many interesting talks to attend, so I'm quite busy right now.

Will try to give some updates while I'm here, still too excited.

This year I couldn't participate in the CERT, since there are already too many people. Well, at least I feel safe here 🙂

Garmin eTrex 30x and OpenStreetMap

I recently bough a Garmin eTrex 30x in preparation of a bigger adventure happening next year 🙂

I choose the eTrex 30x because it was an affordable, outdoor-proof, quite robust and long-lasting GPS device for outdoor Trekking. I need a device that has some hours runtime to be able to follow and record tracks.
And I wanted a device with a significant amount of storage, where I can put OSM (OpenStreetMap) maps on.

The procedure is documented sufficiently insufficiently, but fortunately there are enough informations available, so that you can put the steps together. I try to write here down, what I have done to bring multiple recent OpenStreetMap-maps to your device.

This post is based mostly on the OSM Wiki page for Garmin [1]

Put multiple OSM maps on your Garmin eTrex 30x

First you need a new SD-Card, where the maps will be located. I prefer to write directly to the SD-Card, but you can go as well through the USB-Mass Storage configured Garmin. Your choice 🙂

FAT32 formatted SD-Card works pretty well for me. I have not tested any other filesystem and since most of the pre-build OSM Maps are blow 4 GB, this should be fine. Yes, it's an outdated, crappy filesystem, but it does the job.

Download the prebuild-Garmin image files from [here]. You may have to look a bit around, but in the end you will find what you need.

Store the extracted gmapsupp.img files in the folder "Garmin" on the SD-Card. You may need to create this folder, if it does not exists yet.

To store multiple cards on the SD-Card just rename them, but keep the .img ending. Keeping the ending is an assumption by myself, I have not tried it out, but would not recommend removing it in order to prevent confusions.

Evernote wants to read your notes

Evernote recently announced, that some user's note will be subject to a machine learning process.

Although they claim to stuck to their Three Laws of Data protection, but the update is, that a Evernote employee may read your notes in order to check and validate the machine learning algorithms.

I personally do not like to have a machine read through my notes. There are other applications, where this might be useful, but not for my notes.

You can opt-out from this program in your personal settings.

In your personal settings in the Browser you can opt-out from this services



It seems that Evernote has changed the strategy to opt-in.

As a reminder: you can always encrypt part of your note using a password. Unfortunately you cannot encrypt a whole note or notebook at this moment.
