  @Jaime, Re the printer example, it's bogus sure but taught that way most of the time. At least it was a few years ago, hopefully that part of the curriculum changed. I know it took me a good while to get out of the "OMG this isn't strict OOP therefore it's bad" mentality.<... read more »

  @Ben, No, never heard of Tosh.0. I tried checking it out but comedycentral doesn't like Canucks much and won't let me view it :( Looks good though, I'm sure it's available elsewhere I'll have a look when I have a bit of spare time. As far as the service/persistence thing goes... read more »

  Wouldn't that make more sense if var teenager2 = new Girl(0,"Kit", 17); would be the one responsible for throwing the error, in which case your service layer can simply rethrow it and you've now killed two birds with one stone?... read more »

  We use what is called "honeypot captcha". Since most spambot don't parse and evaluate CSS (they aren't that smart yet) we leave a hidden input field on the form. On form submission we make sure it's empty. If it's filled you can be pretty sure it's a bot. All you need is a... read more »
