Fun facts about Marvel Comics movies
I am a big fan of the Marvel Universe and the superhero movies they release each year. There are two fun facts about those movies:
- The Marvel movies have after credits: when the movie ends and the credits start rolling, do not leave the movies. Instead hang on for a while after the credits you might observe a scene or two.
- Stan Lee appears in the movies: if you pay close attention, like hunting for an Easter egg, Mr. Stan Lee will make an appearance in the movie as a background character.
To give you an example, in the gallery below, I show you Stan Lee, the movie and at which time he makes a random appearance in the movie:

Downloading your Facebook data
When you use Facebook, you can at any time request to download your data from Facebook servers. You usually do that when you decide to close your Facebook account, want to run offline analysis on your Facebook data, or when you are curious to see what data Facebook gives back to you.
In this article, I am going to explain, in layman terms how to request your data and what to expect to find in the requested data archive.
Let’s get started! Continue reading “Downloading your Facebook data”
Using C/C++ TLS callbacks in Visual Studio with your 32 or 64bits programs
In the following article, I share with you how to use TLS callbacks in your C/C++ program compiled with Visual Studio.
Background
TLS (thread local storage) callbacks are a mechanism provided by the Windows loader to give your program a chance to do initialization/deinitialization tasks when the process starts, terminates, a thread is created or terminated.
A TLS callback has the following prototype:
typedef VOID (NTAPI *PIMAGE_TLS_CALLBACK) (
PVOID DllHandle,
DWORD Reason,
PVOID Reserved);
The Reason argument can be any of the following constants:
- DLL_PROCESS_ATTACH = 1
- DLL_PROCESS_DETACH = 0
- DLL_THREAD_ATTACH = 2
- DLL_THREAD_DETACH = 3
The TLS callbacks are encoded inside the compiled program’s TLS data directory(IMAGE_DIRECTORY_ENTRY_TLS). Please refer to the PE file structure. Continue reading “Using C/C++ TLS callbacks in Visual Studio with your 32 or 64bits programs”
