How to view Skype messages older than 3 months

This blog post will not be about programing. In this morning, while I was playing with my Windows Phone 7 I run our off battery. Of course the phone closed. The only problem was the PIN, I don’t remember my SIM pin (this is the first time in 7 months when I closed the phone).
I knew that I have the SIM pin in my Skype history, but the message is older than 3 months, because of this I could not access the history from that period of time. The good part with Skype is even if is not displaying all the history, he still persist the older messages.
All the messages can be found in the “%appdata%\skype” in the directory with your Skype user. The easiest way to go at this location is to open a command line and write “%appdata%\skype”. The file that stores all this content is main.db.
Don’t worry about how you can open this file of is encrypted. It is a simple SQLite file. Is not encrypted and can be pen very easily. A good tool for this purpose is Skype Log View. He will automatically open the file for you.
In conclusion, if you need messages older than 3 months from Skype, don’t wary. The message still exists on your PC. In my case, I rediscover the pin of my SIM.


  1. Thank you very Much, this helped a lot :)

  2. im usign skype log view too, and it only finds files 3 months old, even though i set my setttign to record messages "forever"

  3. Unfortunately, same for me. Can't access messages past 3 months. I installed and ran SkypeLogViewer to no avail. Still only last 3 months. Is there another way to bypass the limitation ?

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

Fundamental Books of a Software Engineer (version 2018)

More then six years ago I wrote a blog post about fundamental books that any software engineer (developer) should read. Now it is an excellent time to update this list with new entries.

There are 5 different categories of books, that represent the recommended path. For example, you start with Coding books, after that, you read books about Programming, Design and so on.
There are some books about C++ that I recommend not because you shall know C++, only because the concepts that you can learn from it.
