About Printing On The Web

tl;dr

Printing on the web is very limited. There is CSS3 Paged Media "Last Call" spec, that improves things, but has not been adopted by browsers yet. How about creating a new "WebPrintAPI" that does not use the DOM but is more like a simple canvas API? Would such a simple API be helpful for your printing needs on the web, or is it just suitable for very special use cases like PDF.JS?

Please leave a comment - I would really like to get your feedback on this!

The new Secure Password Hashing API in PHP 5.5

The [RFC for a new simple to use password hashing API][rfc] has just been accepted for PHP 5.5. As the RFC itself is rather technical and most of the sample codes are something you should not use, I want to give a very quick overview of the new API:

Why do we need a new API?

Everybody knows that you should be hashing their passwords using bcrypt, but still a surprising number of developers uses insecure md5 or sha1 hashes (just look at the recent password leaks). One of the reasons for this is that the crypt() API is ridiculously hard to use and very prone to programming mistakes.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
