This is a spaceship operator: "<=> ". It's still being discussed but there's a big chance you'll get to use it in PHP7.
The operator returns 0 if both operands are equal, 1 if the left is greater, and -1 if the right is greater.
Instead of this
function order_func($a, $b) {
return ($a < $b) ? -1 : (($a > $b) ? 1 : 0);
}
you can do
function order_func($a, $b) {
return $a <=> $b;
}

http://www.theguardian.com/info/developer-blog/2015/jan/05/delivering-continuous-delivery-continuouslyIn 2011 the Guardian deployed the software behind the website 25 times. It was a laborious and fairly manual process. In 2014 we made more than 24,000 highly automated production deployments. Why and how did we do it?
All operating systems contain a set of default trusted root certificates. But CAs usually don't use their root certificate to sign customer certificates. Instead of they use so called intermediate certificates, because they can be rotated more frequently.This tools downloads all the intermediate certificates in the trust chain.A certificate can contain a special Authority Information Access extension (RFC-3280) with URL to issuer's certificate. Most browsers can use the AIA extension to download missing intermediate certificate to complete the certificate chain. This is the exact meaning of the Extra download message. But some clients (mobile browsers, OpenSSL) don't support this extension, so they report such certificate as untrusted.
A server should always send a complete chain, which means concatenated all certificates from the certificate to the trusted root certificate (exclusive, in this order), to prevent such issues. Note, the trusted root certificate should not be there, as it is already included in the system’s root certificate store.
There are many falsehoods programmers believe about geography, about addresses, about names and about time.
Elasticsearch is a lightning quick open source search server. It's java-based (but don't let that scare you) and can index and search documents. If you want to know more about it, watch this excellent talk by Ben Corlett. https://www.youtube.com/watch?v=waTWeJeFp4A For a recent Laravel project I had…
Today the maintainers of PHP voted on whether they should add return type declarations in PHP7. And guess what, it passed!
So in PHP7 you can declare this function that guaranties that an array will be returned.
function foo(): array {
return [];
}
You will be able to add a return type for closures, function, generators and class methods. Code which does not declare a return type will continue to work exactly as it currently does.

This survey downloaded CSS files from over 8,000 domains and aggregated some data about how CSS is being used and written. I think this can be useful to drive conversations forward about how to organize, think about, and manage larger CSS projects, as well as to look at how the web is evolving.http://reports.quickleft.com/css
A nice collection of input field animations:
A repository is a collection, a collection that holds entities and which can filter and return entities back based on the needs of your application. How it actually holds those entities is an implementation detail.http://shawnmc.cool/the-repository-pattern
A clear and concise explanation of the repository pattern.
Because the properties for the object are predefined PHP no longer has to store the data in a hashtable, but instead can say that `$foo` is property 0, `$bar` is property 1, `$baz` is property 2 and then just store the properties in a three-element C array.https://gist.github.com/nikic/5015323This means that PHP only needs one hashtable in the class that does the property-name to offset mapping and uses a memory-efficient C-array in the individual objects. Arrays on the other hand need the hashtable for every array.

The arrival of HTTP/2 will require a bit of re-thinking how we handle websites (and webservers), so perhaps it's time to reflect on what those changes can bring. This post is based entirely on theory (the HTTP2 spec), as HTTP/2 is hard to test today (with a lack of servers and browser support).https://ma.ttias.be/architecting-websites-http2-era/
... You can’t accumulate all that knowledge just by writing some code every day. Read books, discuss them with others, read other people’s code, experiment, draw on a whiteboard, or take a walk and just think.http://verraes.net/2014/10/software-design-is-just-theory/
I didn't know, until a colleague mentioned it today, PhpStorm offers a clipboard history.
On the mac press cmd+shift+v to invoke it.
By default it only stores the last 5 copied items, but you can increase that number in the preferences.
Very handy!
