Yeh, it's easy to use it like that for now. I hope they update it later on though. Seems like an missing feature in their otherwise nice firewall rules setup.
Here is an interesting study regarding energy consumption
http://www.cell.com/current-biology/abstract/S0960-9822(15)0...
Tldr days of high level of exercise does not linearly correlate to high level of energy usage. The body can somewhere(brain?) spend less energi to compensate the exercise.
Do the easy stuff first:
1. Enable caching & get the HTTP-headers with e-tags and stuff.
2. Get DB schema with proper indexes & tune database settings.
3. Buy better hardware where there are bottlenecks
4. Fix the software ;)
sqrt(h^2 + h^2)*2 is the max length if your box is 0 is width. The max possible length decreases with sqrt(w^2 + w^2) as width expands.
Assumed the hallways size is symetrical and your object cannot be tilted to achive a smaller length. For example, an object of little height in a high to ceiling room will be possible to tilt with the same measurements are presented above (pythagoras). But if the box has any substancial height you wont get any help from a tilt. A soffa would tilt, a dish washer does not.
