me mude!

me mude de blog a mi propio blog, hosteado por mi usando nikola (usalo!)

aca esta la nueva direccion:

http://www.marianoguerra.org/

los espero por allá, a los que siguen este blog por cosas estilo google connect, el blog tiene rss :)

este blog queda acá por razones históricas, para conservar los comentarios (creo que voy a poder migrarlos) y para no romper links (como si alguien linkeara acá)

nos vemos!

porque los alemanes son tan eficientes?

porque no pueden ver la mitad de youtube

configuration

by default the configuration is looked up in .config/lst
the file contains a JSON object with the configuration of the program with the following subojects:

lists

the lists object contains as keys the names of the lists that you want to configure and as values the configuration for those lists, for example:
if the path to a list doesn't exists it's created:

{
    "lists": {
        "links": {
            "format": "src/me/links/%Y/%m.links" // strftime format can be used
        }
    }
}

fields

format

is the path to the list, you can use ~ to refer to the user's home and any format from datetime.strftime
