Re: [PD] efficient approximation of trig functions for hi pass formula (was: could vanilla borrow iemlib's hi pass filter recipe?)
I think a core commenting sprint would be *very* helpful, specially to those of us (me) who would like help in understanding the black magic inside.

That is an important question. Pd code is full of clever tricks and bit hacks for dsp efficiency. What is the origin of q8_rsqrt(), why and how does it work? What about PD_BIGORSMALL() in m_pd.h? And the mysterious UNITBIT32 number in d_osc.c? Ideally such code should be commented not only to denote its function (if necessary) but also to reference the origin so you may be able to find info.

Does anyone know a tool that will display the line number of a vim session in a large rectangle next to the terminal window? The one could do a screencast and just scroll down through the source explaining what each block of code does. Then people could just search youtube for the relevant c source file, and queue up the video and search until the relevant line number appears in the big rectangle.

why not just adding ":set number" into vimrc?
Because it's tiny.

well, you can make change the color of them with :highlight LineNr ctermfg=color if that helps. cterm=bold seems to do the same thing but it might just be my color scheme... you can make invert the colorsceheme for the line number column with a cterm=inverse option, hmm, i actually kinda like that one...
you can also get the line number at the bottom with :set ruler

With X11 and ffmpeg (so, probably Linux):
ffplay -f x11grab -video_size 96x32 -framerate 10 -i :0.0+0,1048 -vf
scale=in_w*8:-1
will embiggen the bottom left pixels of a 1080p display. Add some
swscaler flags to not make it blurry, perhaps, though youtube will
probably blur it for you again. Read man ffmpeg-filters for that.
