## macos – Size and color of letters very difficult to see in the Utilities window

The size and color of the font are very difficult to see in the Utilities window.

Hardware: MacbookPro at the end of 2011.

In addition, the bottom of the window is clear, so Apple's choice of a white text icon on the background of a clear window is almost impossible to see, besides the text is very small.

## Bessel functions – Calculate the difficult integral $ int_0 ^ infty J_0 (x) ^ 4 log (x) dx $

Numerical calculation of integrals of oscillating functions from. $ 0 $ to $ infty $ It is a well-known and difficult problem. Here is an example for which I do not know a solution: I know how to calculate (to thousands of decimals if necessary) $ int_0 ^ infty J_0 (x) ^ 4 , dx $ Y $ int_0 ^ infty J_0 (x) ^ 3 log (x) , dx $, where $ J_0 $ is the $ J $-Function of the ship. On the other hand, I do not.

know how to compute $ int_0 ^ infty J_0 (x) ^ 4 log (x) , dx $ because the magic of Pari / GP's sumalt program does not work here because the exponent is even.

Keep in mind that I do not need this specific integral (which, as far as I know, can even be expressed in closed form), my question is more generally how to calculate an integral with an even number of $ J $ functions multiplied by some slow increase function, such as $ log (x) $.
