Facebook speeds PHP by crafting a PHP virtual machine

  • Posted on September 12, 2016 at 1:05 am

Social networking giant Facebook has taken another step at making the PHP Web programming language run more quickly. The company has developed a PHP Virtual Machine that it says can execute the language as much as nine times as quickly as running PHP natively on large systems.

“Our goal is to make PHP run really, really quickly,” said Joel Pobar, a Facebook engineering manager. Facebook has been using the virtual machine, called the HipHop Virtual Machine (HHVM), across all of its servers since earlier this year.

Pobar discussed the virtual machine at the O’Reilly Open Source Conference (OSCON) being held this week in Portland, Oregon.

Shares its development tools

HHVM is not Facebook’s first foray into customizing PHP for faster use. PHP is aninterpreted language, meaning that the source code is executed by the processor directly. Generally speaking, programs written in interpreted languages such as PHP tend not to run as quickly as languages, such as C or C++, that have been compiled beforehand into machine language byte code. Facebook has remained loyal to PHP because it is widely understood by many of the Web programmers who work for the company.

To keep up with the insatiable user demand, however, Facebook originally devised a compiler, called HipHop, that would translate PHP code into C++, so it then it could be compiled ahead of time for faster performance.

While Facebook enjoyed considerable performance gains of this first version of HipHop for several years, it sought other ways to speed the delivery of the dynamically created Web pages to its billion or so users. “Our performance strategy for that was going to tap out,” Pobar admitted.

HHVM is the next step for Facebook. Under development for about three years, HHVM actually works on the same principle as the Java Virtual Machine (JVM). HHVM has a just-in-time (JIT) compiler that converts the human readable source code into machine-readable byte code when it is needed. (The previous HipHop, renamed HPHPc, has now been retired within Facebook.)

This JIT approach allows the virtual machine to “make smarter decisions at runtime,” Pobar said. For instance, if a call is made to the MySQL database to read a row of data, the HHVM can, on the fly, figure out what type of data it is, such as an integer or a string. It then can generate or call code on the fly that would be best suited for handling this particular type of data.

With the old HipHop, “the best it can do is analyze the entire Facebook codebase, reason about it and then specialize code based on its reasoning. But it can’t get all of the reasoning right. There are parts of the code base that you can not simply infer about or reason about,” Pobar said.

Virtual system speedier

Pobar estimated that HHVM is about twice as fast as HPHPc was, and about nine times as fast as running straight PHP.

Facebook has posted the code for HHVM on GitHub, with the hopes that others will use it to speed their PHP websites as well.

HHVM is optimized for handling very large, and heavily used, PHP codebases. Pobar reckoned that using HHVM for standard sized websites, such as one hosting a WordPress blog, would gain only about a fivefold performance improvement.

“If you take some PHP and run it in on HipHop, the CPU execution time [may] not be the limiting factor for performance. Chances are [the system is] spending too much time talking to the database or spending too time talking to [the] memcache” caching layer, Pobar said.

Four Techniques Local Businesses Should Use for Search Engine Optimization with WordPress

  • Posted on September 9, 2016 at 2:22 am

Hands down, a WordPress website is one of the best investments that can be made in a local company’s online lead generation efforts. Admittedly, it can also be one of the biggest investments. My Local Leads, a Maine based marketing firm, works on design and development as well as continued maintenance of affordable WordPress websites for local businesses across the US. There are undoubtedly some decisions that go into the initial planning and development stages that can greatly impact marketing effectiveness of the site. Then, there are things that require continued and near constant observation and work. These few techniques are important to helping make a WordPress website part of a successful local search marketing campaign.

Choosing the right domain name can be pivotal in helping increase a websites reach, especially in the early stages. It was popular to stuff a domain with keywords, but recent search engine algorithm updates have lessened the value of such a practice. Branding is important for the domain name. It needs to be simple enough for people to remember. If a keyword fits naturally, sure it can and should be added. If it ends up making it too weird, too long, or too hard to remember, it is most likely not worth it.

It is also important to remember to turn on WordPress’s built in SEO tools when putting up a site for a local business. There is a setting under privacy of a WordPress site that will automatically hide the site from search engines, and this certainly is not what anyone attempting to build a site for search engine optimization wants to have set. At the same time, the WordPress website should have the permalinks set to be friendly URLs, which will help with the site ranking.

There are important add-ons that any WordPress website should have including sitemap and SEO tools. The meta titles and descriptions can be easily added with warnings and suggestions through using a tool like Yoast. The sitemap is a factor in overall page ranking and can be done automatically through a plugin whenever new pages or posts are added.

Another factor that business owners will want to keep an eye on with their WordPress site is the actual functionality. The site should load quickly, have no dead links, and have clean code. Ugly and broken code can harm the rankings as well as user experience. Slow sites or sites that go down frequently can also be detrimental to both customer experience and search engine rankings.

Motherboard ECS A55F2- M3

  • Posted on September 6, 2016 at 3:58 pm

Now with FM2

If you remember, the elder brother of ECS-M3 PCplus A55F2 test this time PCplus ever fit in issue 412. Old brother-M3 ECS A55F2 it is ECS A55F-M3 alias minus the number 2 on the naming. At that time, ECS A55F-M3 comes with support for AMD socket FM1 APU with. Now, ECS A55F2-M3 comes with support for the latest generation AMD APU, Trinity, who took FM2 socket.

u6-435-ecsSelain will support newer AMD APU, ECS-M3 A55F2 also added to the display for digital output. ECS A55F-M3 only offer analog outputs in the form of D-Sub 15pin. Digital outputs are added to this is the HDMI.

In terms of main memory slots and expansion slots, micro ATX motherboard is still giving two slots and three slots. Expansion slot is paired ECS PCIExpress 2.0 x16, PCI-Express 2.0 x1, and PCI. Unfortunately, the use of dual slot graphics card, like his brother, will close the slot PCI-Express 2.0 x1 and could complicate the use of a SATA port.

What about the additional facilities? ECS-M3 A55F2 rely more on the facilities offered by the AMD A55 chipset it uses. Therefore, there is no SATA 6Gbps and USB 3.0. Similarly, eSATA and FireWire. Both of these interfaces are not added to the ECS.

For you who like tinkering with computers, this motherboard does provide a number of options for you to adjust the BIOS setup, but there are a number of common options for tweaking is not offered by ECS. There is also no indicator POST process and switch / easy to clear CMOS button on the rear panel. The good, easy way to clear CMOS utilizing the Page Up key on the keyboard still included.

For business solid capacitors, ECS-M3 A55F2 use. Unfortunately, the use of only on the assessed critical. For others, ECS still wearing electrolytic capacitor. Just a reminder, solid capacitors generally considered to have the durability and quality that is better than electrolytic capacitor that is more affordable.

Given that the cost should you spend to redeem, various limitations this is a natural thing. ECS motherboard consign it for you who need a FM2 motherboard affordable and do not need the completeness of all kinds. Good again, ECS still provides a number of distinctive features such as the EZ Charger can recharge your mobile device battery quickly.
