With most installations of X11 / Xlib, there is also an extension library: libXFixes. With this, it is possible to receive an event whenever the clipboard (or any other selection) changes (even if our program is not the owner). [0] I u

I feel as though they should change the name of the paper, because this must be one of the most complex takes on 'defer' that I have seen. They make a classic mistake of trying to solve a problem by adding more complexity. They ca

I had a go at this myself a few years ago [0]. But I wanted a dynamically linked ELF instead of a static one so that I could load SDL, OpenGL, etc. That requires extras like a DYNAMIC section which takes up quite a bit more space. I ended u

I was initially surprised that all the lexers treat "[01]" as four tokens, but it makes sense from the state diagram. In the past I've encountered JSON lexing that only considers token boundaries on "special" charac
