+If you have a property in an object that only needs to be computed once, consider using `cached_property` to store the result and serve for future function calls.
+
+```python
+import functools
+class Number:
+    def __init__(self, n):
+        self.n = n
+    @functools.cached_property
+    def is_prime(self):
+    	return all(self.n % i for i in range(2, self.n))
+```
+
+Let's test it with the Mersenne prime `524287`.
+
+```python
+n = Number(524287)
+n.is_prime
+```
+
+After maybe 1-2 seconds of thinking you should get `True.`
+
+Run it again and the result will be instantaneous!

+You can use Python to quickly spin up a HTTP server. A common use case for me is to quickly transfer files to mobile devices in my internal network. 
+
+```python
+python -m http.server
+```
+
+This will likely start an HTTP server on port 8000 on your machine listening to all network interfaces.
