Hi George,

I have a hunch part of the validation process is no longer valid. It doesn't gracefully log the validation issue, but rather pops a message thus: "ValidationError: Validator "a task is required" failed for path task with value ``"

Pretty sure this isn't right - but I get it even after using the downloaded code for example 11. Is it possible the framework has changed since the book was published?

Kind Regards,
Andrew.

Really enjoying your book. For some reason layout.jade isn't working in chapter 8. Maybe a different version of Express?

I've a problem with the hour17/example04. When I kill one of the child
processes from a second terminal window, I don't get the result of the
Figure 17.3. The console doesn't inform of the process kill, nor the
start of the new child process. Is there any error in the code? I've
tested in Mac and Windows (using the taskkill /F /PID XXXX command).

Error: failed to connect to [localhost:27017]

Anyone experienced the same???

Running the examples with Node.js version 0.10.16 required some minor changes.

The version of Express in package.json needed to be:

"express":"3.1.0"

The initial part of app.js needs to change to:

var app = require('express')(),
    server = require('http').createServer(app),
    twitter = require('ntwitter'),
    io = require('socket.io').listen(server);

server.listen(3000);

With that, the examples run great. Thanks for putting this book out there!

I'm wondering if the rapid upgrades to twitter bootstrap mean the links to 1.4.0 are now defunct. I'm not seeing any bootstrap styling in the Hour 8 examples when I link to 1.4

Fantastic book by the way! Love it. As an old c hacker, a lot of the web concepts are new. The book is perfect for somebody with coding experience but lacking some of the newer web expertise. Brilliant!

Cheers,
Andrew.

SORTED: UPDATED THE LINKS TO BOOTSTRAP 3, ALL GOOD (but a few class names have changed)

Hi George,

I got the following error on the hour13 example 4 of your book, I put it as the following, who define the callback function?

Thanks,

'Examine package.json to understand how to delcare dependencies'

should be

When running example 1 from hour 14, I get:

The same error is reported on ntwitter AvianFlu/ntwitter#146 . The only suggested solution to sync server clock did not help. Any ideas?

Currently the examples run against Express 3.x
