clang colorized html output

I love that clang has COLOURS in its output, but how to keep this formatting when copying the output to a file?

The solution is simple, add a -fcolor-diagnostics option and pipe the result to ansi2html. Of course since most of the interesting output is on stderr, don't forget to correctly redirect it (2>&1).

So in the end

$ clang -fcolor-diagnostics temp.c  2>&1 | ansi2html > temp.html

Many thanks to nemo for sharing this trick and several others on this blog!

pemissions on .ssh

Remember that every user's .ssh folder needs to have 700 as permssion, or ssh will complain and revert to passphrase authentication.

It is also good practice to have authorized_keys as 600.
