Using the xelatex engine fixed the following error for me, when generating a PDF from markdown via pandoc:

pandoc: Error producing PDF from TeX source.
! Package inputenc Error: Unicode char \u8:° not set up for use with LaTeX.

While working with Curses and Mouse I found, that my Mouse error message will not be displayed. I worked around it by capturing the message via eval, calling endwin; directly and displaying the error after that.

#!/usr/bin/perl

package Foo;
use Mouse;

use Curses::UI;

has _cui => (
    isa => 'Curses::UI',
    is => 'ro',
    default => sub { return new Curses::UI ( -clear_on_exit => 0 ) },
);

has _screen => (
    # _screen should be a 'Curses::UI::Window'
    isa => 'Curses::UI',
    is => 'ro',
    default => sub { return shift->_cui->add( 'screen', 'Window' ) },
);

package main;

use Curses;

eval { my $f = Foo->new(); };

if ($@) {
	endwin;
	print $@;
}

dh-make-perl fails when run through sudo:

sudo dh-make-perl --cpan IO::Socket::SSL
...
Use of uninitialized value $orig_pwd in chdir at
/usr/share/perl5/DhMakePerl/Command/make.pm line 281.

Running as root works though.

Accidently instructed mutt to encrypt a message where you don’t have the recipients GPG key? Press Gtrl-G.

Black screen on Windows 7 after Ctrl+Alt+Del? Maybe it’s the broken update KB3097877.

A possible fix for 64 Bit Machines according to Heise Forum:

dism /image:X:\ /remove-package
/packagename:Package_for_KB3097877~31bf3856ad364e35~amd64~~6.1.1.1
/scratchdir:X:\temp

Start screen with a session name, e.g.

screen -S FOO

and filter for that name

ps h --ppid $(screen -ls | grep FOO | cut -d. -f1) -o pid
