[08:46] schestowitzRight-clicking on the pen is an essential part of my workflow. Right-click on a layer in Krita to get the menu, right-click while using the Transform tool to get the transformation options, right-click on the canvas to get the pop-up palette! ...And I'm not even talking about how difficult it is to handle files and the D.E. without right-clicking.

And on its box it says it supports 4K, Bluetooth and WiFi, and has gigabit Ethernet. It's also supposed to have PCI Express!

[09:20] schestowitzTurns out it actually is possible!
[09:20] schestowitzIn fact it is almost too easy with clang/llvm. There are already solutions that attach LLVM bitcode to existing binaries. e.g. gllvm. gllvm basically is a shim sitting between ninja and the actual compiler and injects some behavior for us. This enables the use without having to refit anything in our existing code. You might note that clazy, our most excellent code analyzer, works in a similar [09:20] schestowitz fashion.
