The purpose of life

While a kid, I was having the impression that we need to do something big in our lives, something useful, important, not spend time on stupid things.

Today I realized that I was not right. My mother found a big insect in our backyard, it was eating our plants. And she killed it. What was the purpose of this insect in her life? Did she do something "useful, important, not stupid"? No... It was just eating, moving around, enjoying life. Then it got killed.. But it's fine: she had a great life. At least she HAD one.

I guess it's the same for us: the majority of people are spending their time entertaining, reading, talking, relaxing. And it's perfectly fine! I think we still do something useful, but not in physical world, I mean we build good mood, and we spread good emotions for all the universe. And I like this point of view..

Tea problem

Try to get an "Earl grey" in 2 seconds.

Try now.

Design should be taught in schools.

PS: It can be done much better, but it's a fast and cheap solution :)

To properly resize a vector image, like .eps, in Photoshop, open it with a big size, like 2500px width. Then, convert it to "Smart Objects", and the image will get resized and be very sharp.

Javascript private variables

Notice this function inside the Sencha touch framework:

Ext.apply(Ext, { /** * Returns the current document body as an {@link Ext.Element}. * @ignore * @member Ext * @return Ext.Element The document body */ getHead : function() { var head; return function() { if (head == undefined) { head = Ext.get(document.getElementsByTagName("head")[0]); } return head; }; }() });

I like very much the private variable inside the function. No more need to define another variable inside the main object like this:

var obj = { _head: null, getHead: function(){ var head = this._head || (this._head = document.getElementByTagName("head")[0]); return head; } }
