Ralsina.Me — Roberto Alsina's website

Twitter Off

A week ago, I took a de­ci­sion I had not seen com­ing. I shut down com­ments on this blog un­less the post was tech­ni­cal. Be­cause I could not stand some of the com­ments any­more. I said "com­ments down for a mon­th, and then I'll see if I miss them".

Well, so far I don't, as you can see by this post hav­ing com­ments dis­abled.

To­day, I am re­mov­ing the com­ment track of my life. I an shut­ting down my twit­ter ac­coun­t. Some au­to­mat­ic posts will go out, but I am not read­ing it and am not no­ti­fied of any­thing. Again, it's "twit­ter down for a mon­th, and then I'll see if I miss it΅.

Hope­ful­ly I will not.

Python Trick: the Fundict (or the Diction)

Sup­pose you have made the choice in the past of ex­pos­ing a dic­tio­nary as part of an ob­jec­t's in­ter­face. So, peo­ple are do­ing things like:

object.data[foo]['bar']

And now you want people to not have to specify foo because it can be obtained from somewhere else. In fact, what you want now is to expose something like this:

object.data(bar, foo='foo')

Here's an idea on how to do that with­out break­ing the old code:

class fundict(dict):
    def __call__(self, bar, foo='foo'):
        return self[foo][bar]

That's a dic­tio­nary that's al­so a callable, and thus in­dis­tin­guish­able from a func­tion. A func­tion-­dic­tionary. A fun­dic­t. And of couse, you could al­so do it the oth­er way around, and im­ple­ment a func­tion that works as a dic­tio­nary. A dic­tio­nary-­func­tion, a dic­tio­n. But since that's more work, I used this one.

Twitter Card Support in Nikola

This fea­ture for Niko­la was im­ple­ment­ed by @amok­leben, and now, if you ask twit­ter your site can have it too.

What are Twit­ter Card­s? Did you no­tice that for some sites, when you click on tweets that have links, you get a small pre­view of the con­tent? Well, that's a twit­ter card.

This still needs a lit­tle im­prove­ment to sup­port the rich­er "me­di­a" card­s, but it does work:

Yes, that's a pic­ture of the twit­ter card for this post. How meta, right?

You don't have to do any­thing in your site, but set­ting the "de­scrip­tion" meta­da­ta to your posts helps make this more ac­cu­rate (and it al­so works for google+)
