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

Running as root works though.

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

Besides a couple of minor bugs this release fixes one major bug with php >= 5.4

Don’t want to write things like

app->log->debug("foo $config->{foo} versus ".stat->mtime." seconds");

but rather

app->log->debug("foo %s versus %d seconds", $config->{foo}, stat->mtime);

but Mojo::Log does not support that directly. You could use this:

app->log->debug(sprintf("foo %s  versus %d seconds", $config->{foo}, stat->mtime));

with the downside that sprintf() is called even if the message would not be logged due to your app’s log level being higher than that of the call.

Alternatively you could base your own logger class on Mojo::Log:

#!/usr/bin/perl

package My::Log;
use base Mojo::Log;

sub format {
        my ($self, $level, $format, @parameters) = @_;

        return $self->SUPER::format($level, sprintf($format, @parameters));
};

package main;

use Mojolicious::Lite;

app->log->error("this string %s printf %s", 'uses', 'stuff');
app->log->warn('decimal: %d hex: %x', 16, 16);
app->log->info('pi: %.2f', 3.14159265359);

And it’s output:

[Wed Feb 27 17:24:34 2013] [error] this string uses printf stuff
[Wed Feb 27 17:24:34 2013] [warn] decimal: 16 hex: 10
[Wed Feb 27 17:24:34 2013] [info] pi: 3.14
