1. Filesystems, Disks and Memory
I'm trying to understand the difference between o_direct flag of open system call and dax (direct access) with ext4 filesystem.
According to my understanding both bypass page cache.
But I'm still unclear about the crucial difference between these 2 techniques. If there is a huge difference... (1 Reply)

NAME
Term::Size::Any - Retrieve terminal size
SYNOPSIS
# the traditional way
use Term::Size::Any qw( chars pixels );
($columns, $rows) = chars *STDOUT{IO};
($x, $y) = pixels;
DESCRIPTION
This is a unified interface to retrieve terminal size. It loads one module of a list of known alternatives, each implementing some way to
get the desired terminal information. This loaded module will actually do the job on behalf of "Term::Size::Any".
Thus, "Term::Size::Any" depends on the availability of one of these modules:
Term::Size (soon to be supported)
Term::Size::Perl
Term::Size::ReadKey (soon to be supported)
Term::Size::Win32
This release fallbacks to Term::Size::Win32 if running in Windows 32 systems. For other platforms, it uses the first of Term::Size::Perl,
Term::Size or Term::Size::ReadKey which loads successfully. (To be honest, I disabled the fallback to Term::Size and Term::Size::ReadKey
which are buggy by now.)
FUNCTIONS
The traditional interface is by importing functions "chars" and "pixels" into the caller's space.
chars
($columns, $rows) = chars($h);
$columns = chars($h);
"chars" returns the terminal size in units of characters corresponding to the given filehandle $h. If the argument is omitted,
*STDIN{IO} is used. In scalar context, it returns the terminal width.
pixels
($x, $y) = pixels($h);
$x = pixels($h);
"pixels" returns the terminal size in units of pixels corresponding to the given filehandle $h. If the argument is omitted, *STDIN{IO}
is used. In scalar context, it returns the terminal width.
Many systems with character-only terminals will return "(0, 0)".
