Is there a way I can disable that? Note that I can't format the partition with mkfs unles...

If I use "-O2" flag, the performance improves, but the compilation time gets longer. How can I decide, whether to use it or not? Maybe O2 makes the most difference in some certain types of code (e.g. math calculations?), and I should use it only for those parts of the project? EDIT: I want to emphasize the fact that setting -O2 for ...

When I do "ssh hostname python" it just hangs - it's something to do with the fact that python is interactive. "ssh hostname cat x" works fine. Is there some ssh option that will make this wor...
