Facedetection: Clones in Aldi’s ads (Photoshop Desaster)

I saw Aldi’s (german grocery chain) ad on the last Süddeutsche Jetzt magazine and wondered if they’ve got the approval of all the people / employees on the image. Then i recognized that they are not that many. Because it’s just some people photoshopped all over the seats. Picasa and Processing helped me to analyze the image and find duplicate images.

Some people are up to 9 times on the image. And could only recognize the first 9 rows.

Misfit Shine Adventures


Here’s the answer from Misfit support:
“I am terribly sorry about the misunderstanding we might of had. Only bluetooth is required to sync your data to the app, however, an internet connection is needed to link your Shine to your email address. The data your Shine will provide to us will lead to improving our algorithm and increase accuracy of data. I ensure you that your privacy information will not be shared with any third party companies.”

Remember. The first information was:

“Therefore after that you wouldn’t need the internet anymore of syncing data and viewing your progress.”


I sold my Fitbit Flex because the activity tracker’s data was encrypted and i was forced to upload my data to Fitbit’s cloud in order so see it. My next try was Misfit Shine.

My question to Misfit’s support was:

“Do i need an online account to use the app? Do i need to upload the data to your server? Can i use the app offline?”

Misfit’s support told me that

“You would need an email address to sign in to the app/link the Shine to an email account. The data is sync via Bluetooth. Therefore after that you wouldn’t need the internet anymore of syncing data and viewing your progress. Hope that helps, thanks for your support.”

So i ordered one. But unfortunately that information was not true. Misfit’s Android App does not work at all without internet access. Either when there’s no internet connection or it’s blocked by Privacy Guard or Android Firewall. It does not even sync the tracker via Bluetooth without going online (see the Android Wifi icon).


mitmdump shows that it’s connecting to Misfit’s server to store the data. It doesn’t even calculate the graph on the phone but gets it from the cloud. That’s the output when touching the sync icon:

That’s my motion data! I payed 120 € for the device. I don’t get it why you can’t simply add steps in the app as you told me.

What about my privacy?
Privacy is very important to us here at Misfit. We do not share any of your personal information with anyone without your approval.

I asked the support guy what he thinks about it. I’ll keep you updated.

Arduino UNO on Synology Diskstation DS213j

Finally i got an Arduino UNO connected to a Synology Diskstation DS213j. It took me some time and i had to try several tutorials. I’ll try to document the necessary steps.

1. There’s no optware / IPKG installer for DS213j. Thus you have to build it yourself which is straight forward:

2. Add package sources: http://www.leben-zwo-punkt-null.com/?p=3787#more-3787

3. Modify /root/.profile:
#export PATH

4. Install the modules:
ipkg install kernel-module-usbcore
ipkg install kernel-module-usbserial
ipkg install kernel-module-ftdi-sio

5. There are not all usb packages available for DS213j. Thus i had to install the precompiled SynoZWave. But don’t enable it:

6. Now usbserial works and Arduino shows up in dmesg. But it didn’t work. It took me a while to remember that Arduino UNO does not have a FTDI chip but its own. Thus i had to enable the cdc-acm module:
insmod /lib/modules/cdc-acm.ko
mknod /dev/ttyACM0 c 166 0

7. Yeah! It reads my temperature sensor. It’s quite warm in my office. Good i’m outside.
cat /dev/ttyACM0
22 Celsius, 71 fahrenheit -> 22 Max, 22 Min

Open Data Mashup: Windpower in Bavaria / Windstrom in Bayern

Where are the wind power plants located in Bavaria? Seems there are not that many in Oberbayern and Niederbayern.
Wo wird Windstrom in Bayern produziert? Scheinbar nicht viel in Ober- und Niederbayern.

My old iPhone 3GS just burned and cracked open on the sofa.

Update 2: I called Apple’s hotline. Their robot first told me i had to pay 35 € in advance in order to tell them about the problem. I tried it anyway. The guy on the phone told me that in this case they’ll talk to me without Apple Care. Unfortunately they only proposed a repair option for 160 €.
He couldn’t tell me what would have happened when the phone had burned the sofa. Anyway i’ll now will give my old iPhones to recycling and not display them in the shelf. Poor old first gen iPhone.
And no. I didn’t use the iPhone since 2009 after Apple declared to use location data.

Update: Damn. This thing is still growing. I’ll better bring it outside.


I am happy the sofa didn’t burn, too.
