When Chrome uses more memory than the rpi has it can be killed, solution: use more swap, run nothing else when using chrome, use only one tab, use the official browser instead, use uadblock, use a pi2 or something with up to 16GB ram for bloated sites or tab heavy browsing.

RPi b+ randomly close the browser on a few
Recall Hausdorff-Young inequality: 

For any $f\in L^p(\mathbb{R}^n)$, we have $||\hat{f}||_q\le ||f||_p$, where $p$ and $q$ are conjugate exponents and $p\in[1,2]$. 

It seems to me that it follows that $||f||_q\le ||\check{f}||_p$ by Fourier inversion. My question is: 

Is there an inequality that we can use to bound the norm of $\check{f}$ by the norm of $f$?
