>> Effective Ruby- 30.define_method or method_missing:
- 如果没有找到任何方法，method_missing就会被执行；但是因为又super的原因，这里会有迷惑。def method_missing(name, *args, &block) if @hash.respond_to?(name) @hash.send(name, *args, &block) else super end end; Hash.public_instance_methods(false).each do |name| define_method(name) do |*args, &block| @hash.send(name, *args, &block) end; h.public_methods(false).sort.take(5); 实现了Hash的方法。
AuditDecorator @logger = Logger.new($stdout); private def method_messing(name, *arg, &block) @logger.info("calling '#{name}' on #{@object.inspect}"); @object.send(name, *args, &block); define_method更加适合做这个了。 mod=Module.new do object.public_methods.each do |name| define_method(name) do |*args, &block| @logger.info("") @object.send(name, *args, &block) end end end extend(mod) ; 创建了一个匿名的模块。 —— define_method恢复了内省方法。。 respond_to? and respond_to_missing?>> Effective Ruby- 24. block and ensure:
- 分配-使用-释放；file = File.open(file_name, 'w'_...file.close;因为又垃圾回收的原因，中途发生异常也会被回收资源，但是你不确定什么时候会被回收，所以你如果能及时处理，那更好。那么就算需要begin。。。ensure file.close if file end;也可以通过 File.open(file_name, 'w') do |file| ...end，这种block的方式。块执行晚后文件会被关闭。将资源管理简单化。 简单化的资源管理，也衍生出一个 传block给方法的问题，可以用class Lock def self.acquire ; lock =new ; lock.exclusive_lock!; if block_given? yield(lock) else lock # Act more like Lock::new. end ensure if block_given? # ...end end end; 没有绑定块时候，Lock::acquire 。。。； 类方法上使用块和ensure语句将资源管理的逻辑抽离出来。>> Effective Ruby
- So, be careful when you create things, that are gonna be created on the server side in your real database.The database, by the way? we haven't talked much about that, and that is because we're using SQLite. So, there is nothing to configure,there's nothing to set up, SQLite is now a suitable database for production with Rails. we have tuned it with all the right pragmas,to run SQLite well in production, you of course still need to set up a way to back that up, but everything else is preconfigured for you.>> Rails 8.0.1 You are in good company
- Everything else by default will be behind the authentication lock! There's also a rate limit to make sure that people don't bombard you with attempts to log into users do not have access to.>> Rails 8.0.1 You are in good company

- So, we can do that using the import map pin command. And as you see, now that I hop back into our config import map, we've added the local text pin at the bottom, version 3.0.2. It pulled that straight off NPN, it downloaded that as a vendor dependency that we can check into our version control system. And now, we don't have any runtime dependency whatsoever on NPN, or anything else like that.>> Rails 8.0.1 You are in good company
- Now, let's install something else here, let's install action_text, that is one of the frameworks that's part of Rails, but it's not set up by default, but you can set it up by running rails action_text:install, that's going to give you a WYSIWYG editor. That's currently powered by Trix! The open source, what you see is what you get editor made in JavaScript! And it also sets up active storage!>> Rails 8.0.1 You are in good company
- They have to do that , it's part of their life. If you mess that up you know. It makes everything else particularly hard. So and I heard a great speech from a woman once, who said you can have it all, you just can have it all at the same time.>> work hard but work smart
- For language acquisition succeed anxiety has to be directed somewhere else, not at the language. The child has to assume that she's going to be successful.>> comprehensible input - One way only one way to acquire a language
- My experience took place in 1974, when I was briefly living in exile from California, working at the City University of New York at Queens Collage as director of English as a second language. And like everyone else in New York we lived in a big apartment building. And the apartment next door to use was owned by a Japanese company. And every year there would be a new family in the apartment.And every year there were the children who couldn't speak English.And there I was: director of English as a second language.I will teach English to these children and brag about it to my friends.>> comprehensible input - One way only one way to acquire a language
- Comprehensible input, in my opinion has been the last resort of the language teaching profession. We've tried everything else. We've tried grammar teaching, drills and exercise, computers, etc. But the only thing that seems to count is getting messages you understand: comprehensible input.>> comprehensible input - One way only one way to acquire a language

- Say I'm working at N.S.A. Somebody puts a code on my desk, something nobody else can break. So I take a shot at it and maybe I break it. And I'm real happy with myself, 'cause I did my job well. But maybe that code was the location of some rebel army in North Africa or the Middle East. Once they have that location, they bomb the village where the rebels were hiding and fifteen hundred people I never had a problem with get killed.>> Good Will Hunting (1997)Movie Script
