binary - View Perl Variables as Bytes/Bits -


disclaimer: it's been ages since i've done perl, if i'm asking/saying stupid please correct me.

is possible view byte/bit representation of perl variable? is, if like

my $foo = 'a';

i know (think?) computer sees $foo 

0b1100010

is there way perl print out binary representation of variable?

(not asking practical purpose, tinkering around old friend , trying understand more did in 1997)

sure, using unpack:

print unpack "b*", $foo;

example:

% perl -e 'print unpack "b*", "bar";' 011000100110000101110010

the perldoc pages pack , perlpacktut give nice overview converting between different representations.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
