I think he might make a creepy young Doc Brown from back to the future…

Now this is at least a way of making me make time to do an iron man blog post…

Of course, I misread the post, I missed the part about still being in the aggregator, which I am not, due to my utter failure at blogging. :)

Fey is a framework for representing database schemas and generating queries from that representation. Fey::ORM is a SQL-lovers object-relational mapping built on top of Fey’s impressive SQL generation capabilities.

I do mean impressive, as Fey is able to infer join conditions entirely on its own:

# A User has many units, and units have many users, via the lnk_unit_users table.

my $unit_users = $schema->table('lnk_unit_users');
my $unit       = $schema->table('lkup_unit');

my $select_units = $factory->new_select
    ->select($unit)
    ->from($unit, $unit_users)
    ->where($unit_users->column('user_id'), '=', Fey::Placeholder->new)
;

has_many 'units' => (
    table       => $unit,
    select      => $select_units,
    bind_params => sub { $_[0]->user_id },
);

So, when I go $user->units, I get an iterator object full of Units, which executes the following sql:

SELECT *
    FROM lkup_unit 
    JOIN lnk_unit_users ON (lnk_unit_users.unit_id = lkup_unit.unit_id) 
    WHERE lnk_unit_users.user_id = ?

Note, in my $select_units query I did not specify the join condition, I merely passed two Fey::Table objects, and using the foreign key constraints Fey figured out what to do.

I think this is pretty cool. :)

I think it’s also not as obnoxiously colored.

I was quite nervous, but it turned out alright. I hope next year I can give a more interesting talk.

Oh, also I met a bunch cool perl people, including Jonathon Rockway, who is coincidently one of my new co-workers.

I’m sure there’s something my ~/bin written in ruby I could have used, but instead of doing that, I downloaded the Camping microframework and put together a very simple time-tracking application.

It does not feature authentication (right now) because camping/session.rb seems to be broken.

Here’s the source code: jot.rb

So, for the time being I will use wordpress. Even if it is slow.

Being a lurker in #haskell I have been aware of the development of xmonad, which is a dwm-like window manager written in haskell. I tried xmonad a few months ago, and it was okay. It was missing some features of dwm that I thought I needed, like tags. I continued using dwm.

XMonad development has continued on, with many contributed extensions being added (including novel layout algorithms), and as of yesterday I decided to take the plunge and start using it.

So far, it requires a lot less changes to the config file to behave the way I want.

(Footnote: In fact, I first heard about dwm from Don Stewart, who is also one of the hackers behind xmonad.)
