• Posted MongoDB drops support for Perl 5.8. to Mike Friedman

  One of my many rules of software engineering, born of more than a decade seeing things done the Wrong Way, is that serialization must occur only at the extreme edges of your program. At all other points you should, if possible, deal only with structured data. The lack of it in one crucial area of…

• Commented on Fast datetimes in MongoDB
  Time::Piece is definitely a possibility. The only difficult part is that the code that deserializes the returned datetime data from MongoDB is all written in C, so adding support for other date/time modules takes a bit of work. But if...
• Posted Fast datetimes in MongoDB to Mike Friedman

  One of the most common complaints about the Perl MongoDB driver is that it tries to be a little too clever. In the current production release of MongoDB.pm (version 0.46.2 as of this writing), all datetime values retrieved by a query are automatically instantiated as DateTime objects.

• Duncan White commented on Beginning Perl (Wrox) is now released

  Ovid, really liked the book (actually still going through it), it's nicely written, but there are loads of typos, especially wrt code indentation (?was there a space/tab confusion that running the whole book thru 'expand' could have fixed?).

  Most seriously, you've made a serious logical error pp300-306 ("grepping for primes"), where your prime caching is broken. I've submitted an errata report via wrox, but noone's got back to me yet (a week or so later!). Have they passed it onto you yet?

  The core of the logical error was:

  my @primes = grep { ( exists $is…

• Ovid commented on Beginning Perl (Wrox) is now released

  Duncan, thanks for the report. It looks like I'm going to have to try and write something up to fix that for the errata. Damn!

• brian d foy commented on Another strike against AUTOLOAD

  I don't see this as a strike against AUTOLOAD but a consequence of using a dynamic language. You could have the same "method doesn't exist yet" problem without AUTOLOAD. The problem I see is that Smalltalk's omniscience has invaded Moose, but that design doesn't really work when you can't know everything. It's why my Perl class browser project ultimately failed.

  I don't dispute that this is mystifying to new Perl users, but I don't see that as a problem. Power and pro-level tools tend to mystify new users, but when they become experienced users, they have a lot of, well, power.

• Pedro Melo commented on Another strike against AUTOLOAD

  Actually, what you found was a bug in Redis, congrats! :)

  Redis.pm must keep track of the current database to deal properly with reconnect. I should have the time to patch this in soon, but if you really need it, you can send me a pull request, I'll cut a release immediately.

  Bye,
