I want a shortcut to hide the top bar and dock, so I thought the best way to do that would be to figure out a terminal command which does the same.So, can someone tell me the command to do so or another way to make the shortcut work?
I have a matrix
$$ A= \begin{pmatrix} 0 & a & d & c\\ \bar a & 0 & b & d \\ \bar d & \bar b & 0 & a \\ \bar c & \bar d & \bar a & 0 \end{pmatrix} $$
as you can see the matrix is always self-adjoint for any $a,b,c,d \in \mathbb C.$
But it has a funny property (that I found by playing with some nu...
I consider the curve $c(t)=(x(t),y(t))$ in $\mathbb{R}^2$ such that
$\frac{d^2x(t)}{dt^2}=-(a\sin t+b)\frac{dy(t)}{dt}$
$\frac{d^2y(t)}{dt^2}=(a\sin t+b)\frac{dx(t)}{dt}$
$a,b\in\mathbb{R}$
Is the orbit curve of solution of above equations known?
I have a big mp3 file including more songs. Is there any way to split the file by detecting silent parts? I would prefer a command line tool (e.g. ffmpeg).
