The best CDN for jQuery in 2012

jQuery

Since its creation by John Resig in 2005, jQuery has become one of the most widely used JavaScript libraries on the planet. It’s used by more than half of the top 10,000 websites in the world, and keeps getting more popular every day.

One question web developers using jQuery are faced with is how they should host the jQuery file. Should they host it themselves, or should they use one of the freely available content delivery networks (CDNs)?

How popular is Varnish? (Plus words from its creator)

Varnish HTTP acceleratorA really effective way to speed up a website is to add some form of caching layer in front of it. If your web server doesn’t have to keep generating the same web pages over and over, odds are things will be a lot faster for your site visitors. This is where Varnish comes in.

According to our research, 5.2% of the world’s top 10,000 websites are currently using Varnish, a popular open source HTTP accelerator (also called a reverse proxy) that acts as a caching layer between a website and its visitors.

jQuery

We’re big fans of the JavaScript library jQuery, and it appears we are far from alone. As of June this year it’s used by 54.7% of the top 10,000 websites in the world. That’s a massive endorsement by the world’s web developers. It’s also a significant step forward from two years ago, when 28% of the sites used jQuery.

75% of top 10k websites served by open source software

open source web servers

We have analyzed the top 10,000 websites in the world to find out what web server software they are running. Here is what we found out.

First of all, it is clear that open source software rules the roster. This largely thanks to two massively popular open source projects: The Apache web server, and the nginx web server. Together they account for at least 61% of the top 10k sites.

Linux kernel development by the numbers

In the report “Linux kernel development,” the Linux Foundation details the development of the Linux kernel by presenting fascinating statistics.

The report contains lots of amazing numbers, which together offer an insight into the tremendous amount of work that goes on behind the scenes to develop the kernel, the core of the Linux OS.

We jumped head first into the report and extracted as much information as we could. Read on to get a real up-close look at the Linux kernel.

Browser upgrades

Two web browsers currently use a rapid release schedule combined with automated updates. Chrome has had it from the start, and Firefox started using it this summer with the introduction of Firefox 5. Both Google and Mozilla release new versions every six weeks.

There are some differences between Chrome and Firefox as to how these automated updates work, but essentially the idea is that the browser should be updated to new versions automatically without bothering the user, and ensure that as many users as possible are running the very latest version. There are plenty of benefits to this approach.

However, we’ve noticed that this process seems less successful for Firefox than it is for Chrome. We pointed this out a while ago, noting that Firefox now leaves a good number of users behind with every new version.

Nginx

Apache is still the undisputed king of web server software but according to the latest Netcraft Web Server Survey from November 2011, NGINX usage has grown almost 300% over the last year.

In real numbers NGINX increased from about 15 million sites a year ago to 43 million in November 2011. That’s a faster growth than any other web server software tracked by Netcraft.

Since we’re big fans of NGINX at Pingdom, we wanted to try to understand this tremendous growth, so we put some questions to Andrew Alexeev (Q&A further down). Andrew looks after Business Development and Marketing for NGINX Inc., the company formed in October this year, backed by $3 million in venture funding, with the intent to expand the open source NGINX project and explore commercial opportunities.

Don’t panic Ubuntu fans but your favorite desktop Linux distribution has fallen to fourth place in DistroWatch’s latest ranking.

Ubuntu has been overtaken by Fedora, Mint, and openSUSE. Mint now holds the number one spot in all of DistroWatch’s rankings going back at least a year, which leads us to wonder why.

One reason behind this reversal of fortune for Ubuntu could be the change of default interface in version 11.04 or “Natty Narwhal”, released in April 2011. With the new Ubuntu came Unity, an interface previously seen in Ubuntu Netbook Edition, and Gnome was relegated to an option.

There has been quite a bit of controversy surrounding Unity. Now it seems like Canonical, the company behind Ubuntu, may be paying the price for the change. Let’s look at the numbers.

Apple’s iPad owns 88% of global tablet web traffic

There should be no doubt in anyone’s mind that Apple’s iPad is the biggest seller in the tablet space, but we have seen many iPad competitors come out over recent months, including Samsung Galaxy Tab 10.1, Blackberry PlayBook, Amazon Kindle Fire, and many more.

However, despite all these Android tablets, according to comScore in October 2011, 95.5% of all tablet web traffic in the U.S. comes from iPad.

That is a stunning number. So, is anyone really buying all these shipping Android tablets, and what do people do with them after they buy them? Because they don’t seem to be surfing the Web.

FirefoxMozilla’s development pace for Firefox went into overdrive this year, as they adopted a strategy similar to that which Google uses for the Chrome web browser. Mozilla’s new, rapid release schedule for Firefox calls for a new version every six weeks. On Tuesday, November 8, it’s already time for the release of Firefox 8.

But there are clouds on the horizon. For every new version of Firefox that Mozilla releases, a fraction of users are for whatever reason not being upgraded. There’s a long tail of older versions starting to form, and over time this may accumulate enough version fragmentation that it could become a real problem.
