Re: [nodejs] Running node on port 80?

To run on port 80 you need to run as root, so it's best to drop privileges after setting up the listening port. You do this with process.setgid and process.setuid. See how Haraka does it here: https://github.com/baudehlo/Haraka/blob/master/server.js#L267 Though I highly recommend running a front e

You're just fundamentally misunderstanding how async code works (a common problem with people new to Node). You're coding as if things are synchronous. You need to do some of the basic ground work first to understand this. Try http://nodebeginner.org/ On Tue, Sep 23, 2014 at 2:16 PM, kurofune wr

Re: [nodejs] Callback hell and how to get around it?

}); }); It's more code, but it improves the error checking. If it didn't have that "if" statement in there it would be a lot simpler - async code doesn't deal well with "if" statements I've found (there's no way to short-circuit). Matt. -- Job boa

Re: [nodejs] A fair test between bcryptjs and twin-bcrypt

Two issues: 1) Why would you expect it to be faster? It's pure JS using asm.js (which Node doesn't support), vs bcrypt is compiled C code. And 2) Being slow is a feature of bcrypt - it makes brute force cracking harder. On Wed, Sep 10, 2014 at 10:54 AM, Adrian Lynch < adrian.ly...@concreteplatform

Re: [nodejs] node.js vs python tornado

The big difference is that the entire Node.js ecosystem is built around async code. With Tornado if you use a library like an XML parser, which loads in external content via entities or xinclude, those will be loaded synchronously and block your event loop. Similarly for all kinds of other librarie

Re: [nodejs] Fundamentals: Callbacks in Node?

I don't know where you heard that, but it's not true of V8 (or I doubt of any modern JS engine). There are plenty of benchmarks out there that can prove this. You can however separate out for basic code hygiene - you get a lot of indentation with nested callbacks. Matt. On Sun, Aug 1
