Embrace next generation Javascript, today!

It's a significant update to the language since ES5. At Keymetrics we love innovation and moving forward. Javascript has been evolving fast these days and we are glad to announce support for ES6/ES7! We integrated the Babel project into PM2 to make things easier for developers who want to use it in development or production. Show me some code! This is how beautiful ES6 is: # # file # export class Shape { constructor (id, x, y) { = id this.move(x, y) } get info() { return `Shape has id ${} and is at ${this.x},${this.y}` } move (x, y) { this.x = x this.y = y }} export class Rectangle extends Shape { constructor (id, x, y, width, height) { super(id, x, y) this.width = width this.height = height }} # # file # import { square, diag, Rectangle } from '.

The final draft was actually completed back in April. Final review and voting by the ECMA General Assembly members of the draft will occur this month. It’s expected that it will be accepted and the language updates will end a rather stagnant history of change. Once approved, only minor editorial corrections will be permitted. And then, it’s on like Donkey Kong! If your answer to that question is, "Nope" or "I don’t care yet", then I’d encourage you to explore the real-world usages of ES6 in the wild.

De nos jours, de nombreuses pages Web disposent de contenus riches. Les jeux sur le Web sont en train de se démocratiser. Les navigateurs doivent offrir de meilleures performances. Les éditeurs de navigateurs ont apporté de nombreuses optimisations à leur moteur d’exécution JavaScript, afin d’améliorer les performances de ceux-ci.

Cependant, les performances des applications JavaScript demeurent toujours très en dessous des performances des applications natives. Plusieurs solutions ont été développées par des géants du Web afin de rapprocher les performances des applications Web de celles des applications natives. L’une des premières solutions avait été proposée par Google. ES6 In Depth: Collections.

20 Years of PHP, by Ben Ramsey

I first encountered PHP in early 2000 when I was working for Brian Rudolph at EUREKA! Interactive. It was my first, big job in the industry, and it provided a solid foundation for the rest of my career. As I recall, I was making changes to a website, and I used an FTP program—probably CuteFTP—to connect to the server to access the files. Hypertext Preprocessor.

My last article described the improvements to the hashtable implementation that were introduced in PHP 7. Internal value representation in PHP 7 - Part 2. In the first part of this article, high level changes in the internal value representation between PHP 5 and PHP 7 were discussed. As a reminder, the main difference was that zvals are no longer individually allocated and don’t store a reference count themselves. Simple values like integers or floats can be stored directly in a zval, while complex values are represented using a pointer to a separate structure.

The additional structures for complex zval values all use a common header, which is defined by zend_refcounted: struct _zend_refcounted { uint32_t refcount; union { struct { ZEND_ENDIAN_LOHI_3( zend_uchar type, zend_uchar flags, uint16_t gc_info) } v; uint32_t type_info; } u;}; Hypertext Preprocessor. We are continuing to work through the repercussions of the malware issue described in a news post earlier today. As part of this, the systems team have audited every server operated by, and have found that two servers were compromised: the server which hosted the, and domains, and was previously suspected based on the JavaScript malware, and the server hosting The method by which these servers were compromised is unknown at this time. All affected services have been migrated off those servers. We have verified that our Git repository was not compromised, and it remains in read only mode as services are brought back up in full.

As it's possible that the attackers may have accessed the private key of the SSL certificate, we have revoked it immediately. To summarise, the situation right now is that: Over the next few days, we will be taking further action: Changes to Engine Exceptions in PHP 7.0alpha2+ This blog post is about PHP 7.0 which at the time of writing is currently pre-release software (7.0.0alpha2) and subject to change.

While updating my PHP 7 talk “What to Expect When You’re Expecting: PHP 7″ for the DutchPHP Conference 2 weeks ago I noticed a small but significant change to the new Engine Exceptions feature in the newly release alpha 2. Prior to alpha 2 and as per the Engine Exceptions RFC the exception hierarchy looked like this: BaseException (abstract) ├── Exception extends BaseException ├── ErrorException extends Exception └── RuntimeException extends Exception └── EngineException extends BaseException ├── TypeException extends EngineException ├── ParseException extends EngineException └── AssertionError extends EngineException The primary reason for doing this was to ensure two things:

PHP 7 Benchmarks. If you know anything at all about PHP7, you probably know it's fast. But did you know how fast? The alpha is out and looks very robust, so I decided I would create a new set of benchmarks to include it.
