RubyでJSONのencode/decodeの比較をしてみた結果、ArrayもHashも元に戻る。さすがにHashのKeyのシンボルはシンボルには戻らなかった。そりゃそうだ感あるけど。

	$ irb [~]
	irb(main):001:0> require 'json'
	=> true
	irb(main):002:0> 1.to_json
	=> "1"
	irb(main):003:0> JSON.load(1.to_json)
	=> 1
	irb(main):004:0> 1 === JSON.load(1.to_json)
	=> true
	irb(main):005:0> "hoge" === JSON.load("hoge".to_json)

CMTimeMake vs CMTimeMakeWithSeconds

	NSLog(@"%f", CMTimeGetSeconds(CMTimeMake(3.25, 1))); // 3.000000
	NSLog(@"%f", CMTimeGetSeconds(CMTimeMake(3.25 * 100, 100))); // 3.250000
	NSLog(@"%f", CMTimeGetSeconds(CMTimeMakeWithSeconds(3.25, 1))); // 3.000000
