C++ Summary: pass by value, pointer, reference
I’ve made a small infographic (well, certainly “info”, not so much “graphic” ๐ ) regarding the three mechanisms of C++ variable passing: by value, by pointer, by reference.

Submachine fan tribute video
Recently I have edited a fan tribute video for the excellent game series Submachine by Mateusz Skutnik, with the occasion of the game’s end and 10 year anniversary.
If you haven’t played the games yet, you are missing out: very good and logical puzzles, clean and distinctive design, as well as an extremely satisfying scifi story arc.
The tools and configurations used:
- MovAvi Screen Capture Studio: I used this for capturing gameplay footage off the screen, in 1280×720 (720p) resolution, at 30 fps. Awesome tool — intuitive to use, simple, and quite cheap given that the free alternatives are worse, buggy, and/or riddled with malware.
- Adobe Premiere Pro 2.0: this is an older version that Adobe offers for free now (you’ll need to create an Adobe account for the download). Even though it doesn’t have the full power of the later versions, it is a highly usable and powerful tool. I was very happy to see that Adobe offers this option. I worked in a HDV 720p, 1280×720, 30 fps project; the rendering was done as a Microsoft AVI file type, 1280×720, 30 fps
- Adobe Photoshop CS2: like Premiere 2.0, this older version is offered by Adobe for free and it’s excellent for quite high level hobby usage.

Migration to OpenCV 3
After a longer break in computer vision related projects, I wanted to refresh my memory with respect to their status. Despite being 100% sure that I had left them in at least compilable state, make complained about various opencv functions not being declared in the scope. Cue doom and apocalypse, followed by the traditional cursing of opencv taking place after any change in the system.
Luckily I remembered that a while ago I myself had installed OpenCV 3, so I was able to find the solution:
Instead of
#include <opencv/cv.h> #include <opencv/highgui.hpp>
use
#include <opencv2/core.hpp> #include <opencv2/highgui.hpp>
In CMakeLists.txt I explicitly asked for version 3:
find_package(OpenCV 3 REQUIRED)
