Sun opens 82678 lines of C code today: have a good read! Today Sun started the open sourcing of Solaris by releasing the source code for DTrace. I'm a java guy, with a little experience in C and C++, but not familiar at all with UNIX kernel engineering, so I guess this code will be way off my head. But I decided to download it and take a quick look at it.
The OpenSolaris site has a neat simple design, with a list of blogs on the right, but no RSS feed yet. I hope they'll add that soon.
The download is quick, and I was very happily surprised that you don't have any form to fill out, or email/password to remember to get to it: click on the link and download.
The code?
find . -name '*.c' | xargs wc

So it's 82 kloc (Kilo Lines Of Code) of C code, plus 9 kloc of headers. I guess I need to finish Diomidis Spinellis' excellent Code Reading: The Open Source Perspective which sits in my pile since a while before even starting looking at it!
For all you C people: happy code reading.
