So You Want To Be A Writer - Bukowski



if it doesn't come bursting out of you
in spite of everything,
don't do it.
unless it comes unasked out of your
heart and your mind and your mouth
and your gut,
don't do it.
if you're doing it for money or fame,
don't do it.
if you're doing it because you want women in your bed,
don't do it.
if it's hard work just thinking about doing it,
don't do it.
if you're trying to write like somebody else,
forget about it.
if you have to wait for it to roar out of you,
then wait patiently.
if it never does roar out of you,
do something else.
if you first have to read it to your wife
or your girlfriend or your boyfriend
or your parents or to anybody at all,
you're not ready.
don't be dull and boring and
pretentious, don't be consumed with self-love.
don't do it.
unless it comes out of your soul like a rocket,
don't do it.
unless the sun inside you is burning your gut,
don't do it.
when it is truly time,
and if you have been chosen,
it will do it by
itself and it will keep on doing it
until you die or it dies in you.
there is no other way.
and there never was.

Ilusión de Ebbinghaus Dinámica / Dynamic Ebbinghaus Illusion

El efecto Ebbinghaus es una conocida ilusión óptica que consiste en que dos círculos iguales parecen de distinto tamaño según el contexto en el que aparecen, en concreto el círculo central rodeado de círculos grandes parece de menor tamaño que el rodeado de círculos pequeños... / The Ebbinghaus Effect is a well known optical illusion whereby circles of the same size appear different depeding the context they are in, i.e, a circle appears bigger when surrounded of smaller circles than when surrounded by bigger ones...

Kindle ordena mal mis libros - Kindle items sorted incorrectly

OK, una rápida que me tenía confundido. De vez en cuando mis Kindles (modelos 3 y 4) empiezan a mostrar los libros en orden incorrecto. Más exactamente, estoy leyendo un libro, vuelvo a la vista principal, ordenada por "Mostrar más reciente primero", y el libro que estaba leyendo ha "desaparecido", y me toca pasar un montón de páginas hasta volver a encontrarlo. Ni siquiera está al final del todo, pero se va hacia las últimas páginas. Dándole vueltas y googleando di con la causa, y es curiosa. Como no me hace gracia que Amazon husmeé en mi biblioteca, lo suelo tener largas temporadas en modo avión, fuera del alcance de la wifi. Y aquí aparece el problema, cuando por lo que sea se reinicia o se queda sin batería, pierde la hora y como por dentro funciona con tiempo unix, con todo lo que ello conlleva. En definitiva el pobre se que estamos en 1970, antes de nacer yo y todo. Y claro, llibro leído, libro marcado con fecha de 1970... atrás del todo. Se empiezan a mezclar y no hay quien de con nada. Sincronizar la fecha de nuevo es tan fácil como habilitar la wifi y dejarlo sincronizar. Y para confundir al contrario, uno puede renombrar la carpeta "documents" como "_documents" por un momentillo u otra medida similar. Y ya está.

OK, here's a quick one that got me a bit confused. From time to time my Kindles (models 3 and  4) start showing books in an incorrect order. Specifically, say I'm reading one book, then go to the main view sorted by "Most recents first", and the book I was reading is "gone", only to be found very many pages down. It's not even at the very end, but in general goes near there. Racking my brains and a bit googling later I found the cause, and it's interesting. As I don't like the idea of Amazon messing around with my library, I tend to have it in "Airplane mode" for extensive periods, beyond any wifi's reach. And here comes the problem. When for some reason it reboots or runs out of battery, it loses the time and date, and given it internally works in unix time, with all this implies, the poor Kindle thinks we are back in 1970, even before I was born. Book read, book tagged as last read in 1970. Books get mixed up, and the whole thing is a real mess. Syncing the time and date back is as simple as enabling the wifi a few minutes. To confuse the enemy while you get the right date, you can temporarily rename the "documents" folder to something like "_documents". And that was it.

Basic Lego Geometry Experiments




When you play with some bricks and come up with these things, you realise nothing is left to chance at Lego. Incidentally this happens to be a quite nice way of illustrating the Pythagorean Theorem. I guess I already have an idea for another post...

It's not a motorcycle baby, it's a chopper - Lego Creator 31018






For being a Lego 'Creator', this 31018 set is a very 'Technic' like model, and great fun. For under 10€ you get 129 pieces to build three different bikes.
