| // C/C++ tips for using printf-style functions | |
| // Lots of manipulation can be expressed simply and fast with printf-style formatting | |
| // Also helps reducing the number of temporaries, memory allocations or copies | |
| // ( If you are looking for a simple C++ string class that is printf-friendly and not heap-abusive, | |
| // I've been using this one: https://github.com/ocornut/Str ) | |

This is a quick command I use to snapshot webpages that have a fun image I want to keep for my own collection of WTFViz. Why not just right-click and save the image? Oftentimes, the webpage in which the image is embedded contains necessary context, such as captions and links to important documentation just incase you forget what exactly that fun graphic was trying to explain.
