iPhone 4 BLACK wearing Bumpers

Did you order iPhone 4? I ordered a black model. And I want to get Bumpers for iPhone 4. Writing Bumpers, Apple show us only white model wearing them. I couldn't have imagined the black model with Bumpers. So, I asked a designer to create the image. He created this.





You can see the large image here.

Which color do you like?

Use JavaScript-like "with" syntax in Ruby

JavaScript has "with" syntax. At first, I write a code without "with".

console.log(Math.cos(1/2)); //=> 0.8775825618903728
console.log(Math.sqrt(2)); //=> 1.4142135623730951

Then, I write with "with".

with(Math) {
  console.log(cos(1/2)); //=> 0.8775825618903728
  console.log(sqrt(2)); //=> 1.4142135623730951
}

On the other hand, Ruby has not "with" syntax.

puts Math.cos(1/2) #=> 1.0
puts Math.sqrt(2) #=> 1.4142135623731

Look! I can use "with" in Ruby!

with(Math) {
  puts cos(1/2) #=> 1.0
  puts sqrt(2) #=> 1.4142135623731
}

To do this, I wrote "with" function.

def with(obj, &block)
  obj.instance_eval(&block)
end

So, I can use "with" syntax.

with(Math) {
  puts cos(1/2) #=> 1.0
  puts sqrt(2) #=> 1.4142135623731
}

Of course, other type of object is OK. String, Intger and so on.

with("I love Ruby.") {
  puts reverse #=> .ybuR evol I
  puts gsub(/Ruby/, "YUI") #=> I love YUI.
}

with(1) {
  puts succ #=> 2
}

To buy, or not to buy: that is the question.

Pre-order of iPhone 4 start from the day after tomorrow in Japan. I can't make up my mind to buy. I bought Kindle DX two month ago and iPad last month. So I used a lot of money. As a developer, the high-resolution should be noted.


By the way, which is better, white or black? I thought iPhone should be black. But the white model is cool as for iPhone 4. Black or white: that is the question.
