HHVM Blog:
Announcing a Specification for Hack
February 20, 2015 @ 13:51:15

Similar to how the language specification was released for PHP a little while back, the HHVM team has announced a new specification for Hack, the language they've created as a part of the HipHop VM project that's similar to PHP.

When we announced Hack, we were very excited for the community to get their hands on a programming language that has helped Facebook engineers become more productive in their day-to-day development and became, alongside PHP, the language used when developing applications running on HHVM. At the time of release, we had documentation geared for the programmer using Hack to develop applications. However, we did not have official documentation for those that might want to create a Hack implementation of their own or something like a Hack conformance test-suite. This specification fills that gap. It is the document for the Hack implementer, and an excellent supplemental document for the Hack user.

The remainder of the post talks about some of the reasoning behind creating the specification, pointing to resources where you can help contribute and a few thanks to some of the people that worked on it.

When You're Hacked in WordPress Dealing With a Hacked WordPress Site
February 19, 2015 @ 10:50:30

On the NetTuts.com site today there's a new tutorial showing you what you can do when your WordPress site is hacked.

One of the worst things that can happen to your website just happened: It's been hacked. Somebody broke into your computer and got passwords, or your passwords were weak, or somebody exploited a security vulnerability caused by WordPress or your hosting provider, or something else happened that let a hacker hack your website...What do we do now? It's not the time to feel sorry for yourself, it's time to take action and bring back your website.

They start with a brief look at how a WordPress site might be hacked, not specific exploits, but topics and types of vulnerabilities. Following this they talk about thier recommended steps to do when the hack is discovered including:

  • Shut It Down NOW!
  • Contact Your Hosting Provider for Details
  • Find Out What Caused It and Take Action
  • Fix and Double-Check Everything and Go Live Again

Each step comes with a summary of the steps inside and even a "checklist" of things to verify before bringing the site back up.

Hack Blog:
Async - Cooperative Multitasking for Hack
December 08, 2014 @ 11:56:54

On the Hack blog there's a new post talking about async, a feature in Hack that allows for code to "cooperatively multitask". This gives the language a way to keep moving on in the execution without having to wait for things like database queries or remote file fetches to finish.

This is somewhat similar to threading, in that multiple code paths are executed in parallel, however it avoids the lock contention issues common to multithreaded code by only actually executing one section at any given moment. "What's the use of that?", I hear you ask. You're still bound to one CPU, so it should take the same amount of time to execute your code, right? Well, that's technically true, but script code execution isn't the only thing causing latency in your application. The biggest piece of it probably comes from waiting for backend databases to respond to queries.

She gives the example of pulling in a remote file (HTTPS, where there's a bit more latency) and how to use async, await, WaitHandle, and Awaitable to work around the timing issue. She shows how to make a method asynchronous and how to join the results of the operation back up with the rest of the script. This includes the use of various "handles" including RescheduleWaitHandle, SleepWaitHandle and the AwaitAllWaitHandle. She shows the integration of a custom cURL handler that makes use of this processing, marked async, to multithread the requests to the remote server(s).

Facebook Code Blog:
Announcing the Hack Transpiler
November 12, 2014 @ 12:11:47

On the Facebook Hack blog there's an announcement about a new tool they've created to "reverse engineer" Hack code and turn it back into normal PHP - the Hack Transpiler. There's also more information in the Facebook announcement:

Today, we're proud to announce a first, experimental release of h2tp, or the "HH (Hack) Transpiler," a tool which allows projects that have converted from PHP to Hack to still make releases that target the PHP language.

Since the launch of Hack, many community members have asked us how to manage forward compatibility. Hack is backwards-compatible with PHP - if you're running PHP on HHVM, Hack code will seamlessly integrate with it. But the inverse is not true.

The announcement talks about the things that make Hack, well, Hack and how it's not just a simple find and replace to convert it back into PHP. Their "h2tp" tool also converts things like collections and short lambda expressions back into structured PHP. To illustrate, they include some before and after code, showing the addition and substitution of PHP for the Hack shorthand operators. The post also covers some of the hurdles they faced during the implementation of the "h2tp" tool, including error handling.

HHVM Blog:
Hack Recent Updates
October 22, 2014 @ 09:37:26

On the HHVM blog today they've posted some updates about the language that helps power the HHVM (HipHop Virtual Machine), Hack, and the most recent changes and improvements made to the language.

One thing we haven't talked about much is the progress and evolution of the language itself. We've been busy driving the language forward, improving its PHP base as well as adding new features requested inside and outside Facebook to further increase developers' productivity. But unless you're the sort of person that reads every commit going into the HHVM github repository or every change to our docs site, you probably have no idea about any of these changes since we haven't talked much about them yet.

This post is a "kickoff" of a series of posts they'll be doing covering some of the major changes to the language including:

  • Typechecking new static()
  • First-class enums
  • Better understanding the type signatures of the PHP standard library
  • Covariance

Stay tuned to the blog for the full series.

Allan MacGregor:
Exploring Hack Building a MicroFramework
August 11, 2014 @ 09:09:13

Allan MacGregor has started a new series of posts to his site where he creates a microframework in Hack, the language created by Facebook to compliment their HHVM (Hip-Hip Virtual Machine) project. He sees it as a "learn by doing" kind of thing and wanted to share his results.

I honestly believe the best way to learn something is to get your hands dirty and make mistakes; so instead of writing dozens of post on the many new features of Hack and why they are awesome (in theory) let's build something useful. So to get started I've decided to build a micro-framework using HACK and HHVM, building a simple microframework should be a challenging enough task to illustrate some of the more interesting features of the language and at the same time it has an achievable goal so we don't end on a never ending development cycle.

His framework, one he calls "Slash", will mostly be about creating RESTful applications but it could, in theory, be for any kind of web application. He also mentions some of the other great microframeworks out there already that are well-developed and have good communities behind them (including Slim and Silex. This is just the first part of the series and introduces some of the "why" around his goal. In the next part of the series he'll get into the structure and routing with some actual framework code.

Hack How to open the black box of Hacklang as a PHP developer
June 25, 2014 @ 11:56:44

In this recent post to Reddit, user JordanLeDoux shares some of the basics behind the Hack language (from Facebook) and making a "first jump" into it and its strong typing handling.

codebase. Having built HHVM, they wanted something that would enforce certain behaviors for developers that didn't rely on IDE's interpreting phpDoc statements. Hack's most interesting and largest function is that it adds optional strong typing to PHP, by examining the tokenized code and ensuring that where declared strong typing is respected.

Example code is included showing the different levels of typing and how to use them in a few example functions. He introduces some of the basic types included in Hack (like int, float and bool) and some of the types unique to Hack (like mixed, tuples, resource and closures). There's a brief look at maps, vectors and sets and a link to more documentation if your interest has been piqued to learn more and make that "first jump".
