# Tips & tricks
## Generics
Resources shared between two or more tasks implement the `Mutex` trait in *all*
contexts, even on those where a critical section is not required to access the
data. This lets you easily write generic code that operates on resources and can
be called from different tasks. Here's one such example:
``` rust
{{#include ../../../examples/generics.rs}}
```
``` console
$ cargo run --example generics
{{#include ../../../ci/expected/generics.run}}```
This also lets you change the static priorities of tasks without having to
rewrite code. If you consistently use `lock`s to access the data behind shared
resources then your code will continue to compile when you change the priority
of tasks.
## Running tasks from RAM
The main goal of moving the specification of RTFM applications to attributes in
