  Great article Ovid.

• Commented on The Twelve-Factor App
  Yes - some useful and interesting development standards. I find the 12-app idea of logging to STDOUT interesting. On the one hand with Perl it is much easier to say open() or die ($!); than open() or $log->log_and_die($!); But on...

• Commented on When "unsafety" is a Good Thing
  Buddy - I think you hit the nail on the head when you point to database interaction as an area where a weakly typed language is beneficial. We have strong typing in our (relational) databases, so adding primitive typing in...

  Buddy - great article. If you want to do something close to insert %hash into mytable then have a look at this: https://metacpan.org/module/DAMI/DBIx-DataModel-2.40/lib/DBIx/DataModel.pm#Insert This gives you my $id = $table->insert(%hash); almost as per your request and with minimal overhead....

Comment Threads

• Tom Molesworth commented on I hate unpacking sub calls with shift

  $! is common enough that it shouldn't need comments, though?

  If the argument is that people learning perl won't understand them, I'd disagree:

  open my $fh, '

  tends to be covered very early in most tutorials, and is also described in perldoc perlopentut. To some extent the same applies to $/, reading in paragraph mode or in fixed chunks is something that you encounter very early.…

• Olivier Mengué (dolmen) commented on I hate unpacking sub calls with shift

  Note also that @_ is alias to arguments given to the sub which means that it gives you not only read access to the argument, but also write access if it is a variable.

  my $a = 2;
  say $a;
  
  sub change_arg_0
  
  {
  
      $_[0] = 1;
  
  }
  
  change_arg_0($a);
  
  say $a;

  Reminds me of the NetApp CLI (OnTap)... which forces ctrl-D

• Gustaf commented on Writing Non-Blocking Applications with Mojolicious: Part 1

  Would be of tremendous appreciation if you would consider a rewrite of this Mojo series for current Mojolicious.

  I’m struggling to get a hang of it all, and the example code here dont work on current Mojo version.

  Really great reading tho.

• Gustaf commented on Writing Non-Blocking Applications with Mojolicious: Part 1

  Sorry for speaking to soon. Fresh coffe did it for me, I missed some typos from my part.
