Wir sind alle miteinander verbunden! Meine Ideen für ein nachhaltiges Leben (und ein bisschen Geek-Zeug):

Ages ago I bought a Sony Camera Cyber-Shot DSC-HX5V. And for all this time I did the same for each bunch of data (I know in a windows world all of this is done by the software, ...):

• find the images folder and copy the images to a certain folder
• find the video folder (every time a challenge) and copy the videos to the same folder
• rename all capital JPG into jpg (I hate when its capitalized)
• Use the exif data to add the date to the filenames (with renrot)
• deleted all created *.jpg_orig files (if all was ok - which it ALWAYS was)

What I did not do, but what my amazing script is doing now, too:
• copy accurate GPS data to the SD card
• create thumbnails (png) for the movie files, because I do not know how to get them from the CPI files.

So, as I wrote this cool script to do all the work for me, you can see it too

You can save it as "cool_script.sh" then go to the folder you want the pictures in (it has to be empty)

 cd my_folder

and start it with

 bash cool_script.sh

It can be modified to extract the data from other folders. Also the video files are MTS files, but you can change that, too.

Da wir letzte Woche auf einer Kanutour waren, dachte ich, ich lasse euch mal an unseren Erkenntnissen teilhaben.

Wir waren Campen und konnten unterwegs auf den Campingplätzen eigentlich nur auf frisches Wasser zugreifen und sonst nichts einkaufen. Darum hier unsere Liste mit Dingen, die wir mitgenommen haben, Verpflegung wie Gepäck.

Da wir viel in Urlaub fahren, hat sich für uns eine Packliste bewährt. Da jedes Mal, egal ob nur für ein Wochenende oder ein längerer Urlaub das Gleiche gepackt werden muss, und immer wieder irgendwas fehlt.

There are a lot of different ways to develop your code under Linux. I will show you the ones I know and present you my favorite

Code: MyAppender

Constructor (MyAppender):
    base.File = "C:\\file.txt"; // the file name needs to be set
    base.Layout = new log4net.Layout.PatternLayout("%d{yyyy-MM-dd HH:mm:ss};%m%n"); //optional
 

Code: Calling Class

Initialize the Appender and the Logger: 
   // make sure to use an unique name for the Appender, if necessary (like adding random characters to it)
   // otherwise every instance of the class will log to one file
   private ILog logger = LogManager.GetLogger(typeof(MyAppender));
   private MyAppender myAppender;
 

Constructor (CallingClass):

   myAppender = new MyAppender(); 
   // Set up the logger 
   log4net.Config.BasicConfigurator.Configure(_myAppender); 
   // initialze the settings (especially open the file for logging)
   myAppender.ActivateOptions();
 

Here are some values from log4nets Appenders. The here stated default values are from the RollingFileAppender.

maximumFileSize: [10MB] The maximum size that the output file is allowed to reach before being rolled over to backup files

rollingStyle: [Composite] Defining when the content of the log file will be moved to backup files.
• Once → Roll files once per program execution (Appender's AppendToFile property is set to false, otherwise the Appender would append to a single file rather than rolling the file each time it is opened)
• Size → Roll files based only on the size of the file
• Date → Roll files based only on the date
• Composite → Roll files based on both the size and date of the file

maxSizeRollBackups: The maximum number of backup files that are kept before the oldest is deleted. (The maximum applies to each time based group of files and not the total)
• 0 → no backup files (file will be truncated when it reaches maximumFileSize)
• <0 → no deletions (very slow performance, if large number of files have to be rolled over).

staticLogFileName: [true]
• true → always log to the stated file name (and then roll over to filename.1)
• false → start with logging to filename.1

appendToFile: [true] Indicates whether the file should be appended to or overwritten.
• false → the file will be overwritten
• true → the file will be appended to

preserveLogFileNameExtension: [false]
• false → the file name extension won’t be preserved (file.log will be rolled to file.log.1)
• true → the file name extension should be preserved (file.log will be rolled to file.1.log to maintain program associations)

countDirection: [-1] Indicates if the current file is the lowest numbered file or the highest numbered file. By default newer files have lower numbers. For infinite backups use countDirection ≥ 0 to reduce rollover costs.
• < 0 → i.e. log.1 is most recent, log.2 is the one written to before, etc... (writes always in log.1)
• ≥ 0 → does the opposite: i.e. log.1 is the first file made (oldest file), log.5 is the 5th file made (and newer), etc. (writes in log.n)

@addtoreset{figure}{section}

I tend to get problems within Qt Creator looking like that:

error: undefined reference to `vtable for MyCLass'

In that case you have to
• check if you have your classes .cpp and .h file in the .pro file
• then do "run qmake"

Now and you should be able to compile again without warnings
