• Commented on A Simple Mojolicious/DBI Example
  Leaving an SQL query prepared for the entire lifetime of the process is not a good idea to adopt as a style. This is highly dependent on the type of application you are writing and the RDBMS you are using....
• Commented on A Simple Mojolicious/DBI Example
  Thanks Joel! I did not realize just how easy it was to start writing Mojolicious apps. I do webapp+database stuff all the time, and having a small but concrete example directly relevant to something I’m working on really helps....

• Posted YAPC::NA 2012 After Action Report to lajandy

  YAPC::NA 2012 was excellent! I really want to congratulate the organizers, staff, and sponsors for putting together such a well-organized, informative, and fun event. I had not been to a YAPC in a couple of years, and this year's conference made me wonder why I had stayed away so long. It was…

• Commented on What should be core in Perl 5.16?
  My knee-jerk reaction is "no more stuff in the core!" Core Perl 5 is already getting bloated to the point *nix distributors are considering removing it from default installs. But after reading over others' comments, I do think there are...

  I have added an additional example using a more consistent style. Just because the template CAN do lots doesn’t mean that it should :-)

  Well written as always.

  My way of explaining ‘The controller, then, should be thought as…’ is:

  o The Controller is like a human manager, who know (1) what needs to be done, (2) why, and (3) when.

  o Model and View are workers, who know (4) how things are done, and so do them.

  In short, the manager takes decisions and the workers carry them out.

  MVC then is just like any (functioning!) organization.

  Cheers

• Aristotle commented on A Simple Mojolicious/DBI Example

  So yes, this is not perhaps a “best practices” example, but neither was it meant to be. It was meant as a “my first webapp”.

  Understood, and taken as such. My comment was likewise meant not as a voicing of concerns but as “To whomever found this useful to learn from”, as a map of what follows. That is why I wrote out the rationales and stressed that the example is not wrong – i.e. those things I listed are concepts not rules, to be applied with judgement.

  (I made to add an example to illustrate the points concretely, but by then…

• David Oswald commented on A Simple Mojolicious/DBI Example

  This is a nice, simple example. Howoever, I think that any application written as an example of using DBI with Mojolicious should provide the good example of database connection management. Eventually that connection is going to be dropped.

• Joel Berger commented on A Simple Mojolicious/DBI Example

  That logic would almost certainly go in the db helper. I think that would make for an excellent follow-up post! Go for it. In truth I use DBIC mostly so I don’t need to handle that myself, therefore I don’t trust myself to write it.
