new on bugs.kde.org – aliases
I turned on aliases awhile ago on bugs.kde.org. Aliases are a way for people to reference a bug number based on some nice text that is given to the bug rather than by the bug number. You don't have to give every bug an alias, but it seemed like a useful feature to have. If nobody likes it, then we can turn it off, but hopefully people are already using it and i'm just not aware of it. 
figure out where your build errors are
I'm fortunate enough, both at work and at home, to have multiple machines to distribute my compiles to. This means I'm generally using something like 'make -j5' or 'make -j10' to build stuff with. However, a lot of times, especially now with cmake, I'm not completely sure what exactly caused my build error when I have one. The trick that i've started using is running 'make -i -j10' first - which means make builds the whole tree and doesn't stop on errors - and then going back and doing a single 'make' to figure out what didn't compile.
Perhaps I'm late to the party with this, but since it's been rather useful for me, so I thought I would share.
