How does bash tab completion work?
...m), completions for a lot of commands are installed, and as Wrikken said, /etc/bash_completion contains a bash script which is then often executed at shell startup to configure this. Additional custom completion scripts may be placed in /etc/bash_completion.d; those are all sourced from /etc/bash_co...

You should implement IDisposable whenever your type "owns" an unmanaged resource, either directly (usually via an IntPtr) or indirect...
Why is using the JavaScript eval function a bad idea?
... for injection attacks
Debugging can be more challenging
(no line numbers, etc.)
eval'd code executes slower (no opportunity to compile/cache eval'd code)
