It seems the craft mania did reach Germany. 

So I tried one of those beers tonight: Das Helle!

And once again.. I am not a craft beer guy. I am just way to plain and simple.

Compare it with ice cream. I prefer vanilla or pistachio to any garlic induced fish ice cream things.

Maybe I am boring or just to German. But my beer taste is not complex :/

Offene Probleme

I just hit a dead end.

  • it basically already exists in Form of, wine imdb, beerdb and similar projects… yet they all lack an combining app. But app development was never a strong point on my cv.
  • Picture archive: 145k+ pictures and no real solution in sight. How to handle such an amount of image files. Over network. Should I begin from zero just to realise there does exist something? 
  • Robot localisation: I acknowledge time money and space to develop and test an ultrasound based cheap solutions for that issue. Not even sure it can be done done at way

Any help is welcome.

Joe Dampf in allen Gassen

Choosing a characters name for your kids book seems to be hard work.
So lots of authors choose to go the easy way out:
Currently we read „Mon Bus
A bus driver named Joe drives willy nilly through the city and picks up al the dogs and cats.
Just to put them on plane boat and in a train.
Of course he gets fired.
But there seems to be new work for him.
At the Zoo!
But here he is not very careful at his work, also!
The Gorilla escapes, lets all animals free..and in the end his wife has to bring them back again.
I guess he gets fired, again.
What next?
Joe le taxi?
I do not know, but will keep you updated!

„Can you tell me the time?“
„Wait, let me just open my phone.“

This is a daily routine in our living room, we do not have an open clock there.
„We don’t need one, we have enough electronic devices, which display the time!“

Yes, but only when one opens the phone or starts the TV.

I couldn’t live in that medieval condition of timelessness any more!

So I bought a time display for the Raspberry.
A TM1637 based 4 digit 7 segments display.

Hardest part is finding the right sources.
I had to go onto that netherlandish page to find a solution:

But as you can see, it is working:


Hooray! Time!

170 Stunden Mozart

I did it!
I listened to all the music of Mozart.
170 CDs, 170 hours.
I started this in July 2016, every day to and from work I had it on my ears.
From Köchelverzeichnis 1 (Menuett und Trio, Salzburg 1762) to KV 626 (Requiem in D minor, Wien 1791).

I have never been a real fan of Mozart.
Always did find his life to pompous.
And now I can say, I am also not a big fan of his music.
Some pieces are quite alright.
But for me, there was always something missing.
There are some that are moving, yes.
But nothing could hit me like the 3 Bs:
Bach Beethoven .. Bartholdy

Now, what next?
Don’t know. Will listen to my fav station BR Klassik for some time.
All of Wagner? Maybe.
That would be some, why not?

Fotoarchiv / Backup

My Dad has quite the picture collection.
>200000(500 GB) of digital images.
Resting on 2 USB harddisks at home.
That bothered me quite some time.
Those 2 disks are the only backup and for us kids nowhere easy to reach.

So, why not create a solution by myself.
It has to be cheap, really cheap.
And easy to access.

Well, 80€ for 3 TB and 10€ for an Orange Pi.
(and my blog server)
That is all one needs!

First, create 2 Samba shares on the PI:
Fotos and Upload.
Dad will copy pictures into Upload, from there the PI copies it into the Fotos Share, where he can access them.
Fotos is mounted read only, there you go, encryption virus, that could possibly infest my dads PC.
A small script checks every 5 minutes, whether there is new content in upload.

That’s it!
It took me 2 Days, to copy all data into that folder and now he has 200k pictures available for all users of his network.
(And he crashed Adobe Lightroom with it;))

And no the hard part:
Take the hardware, duplicate it somewhere.
Every PI now connects to my server via autossh and some magic portforwarding:

autossh -M 20070 -q -f -N -i /home/autossh/.ssh/id_rsa -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -R 7022:localhost:22 -R 7888:localhost:8888 -L 8022:localhost:8022

„-R 7022:localhost:22“ takes my local ssh port and forwards it to my server as 7022
„-R 7888:localhost:8888“ takes my local RPi Monitoring port and forwards it to my server as 7888
„-L 8022:localhost:8022“ takes the remote port 8022 and forwards it to my local port 8022
this is the important part.

Because now I am able to sshfs from the remote remote PI via port 8022 the share of Fotos to my local mount point.

Next step:
Setup script to rsync /sshfs/fotos /mnt/fotos
This is where I am currently „stuck“
20 of 500 G transfered, after a weekend of 100k/s
I will not go higher with the bandwidth as my parents still want to use the internet.

Major downside so far, it is hard to extend. Further clients need way too much skripting, no plug and play.
Maybe some config file storing on the blog server..idk

Fun fact, I tried torrent, but a 40MB(?) torrent file for all 200k pictures crashed every client I used;)
