Not fast enough, not broad enough: The US Internet in 2013

Say good-bye to Internet’s narrowband yesterday of modems when a great connection could bring you the Internet at up to a breath-taking 53.6Kbps (Kilobits per second). Today, only 3 percent of U.S. Internet users are stuck at dial-up speeds. Better still, the Pew Research Center’s Internet & American Life Project reports that “As of May 2013, 70 percent of American adults ages 18 and older have a high-speed broadband connection at home.

That’s 4 percent better than April 2012, but don’t get ready to throw a party quite yet. Both Pew and the FCC define broadband as being 4Mbps (Megabits per second) down and 1Mbps up. According to the Akamai State of the Internet report for the first quarter of 2013, the United States’ average broadband speed is only 8.6Mbps (PDF Link).

Nginx, the popular open-source Web server, goes commercial

Anyone who pays any attention to Web servers knows that Apache is the most popular Web server. What only professional Web developers and administrators know is that Nginix, a high-performance, open-source Web server, is battling with Microsoft’s Internet Information Services (IIS) for second place.

Now, in order to leapfrog IIS and claim the No. 2 spot for itself, Nginx (pronounced Engine-X) has announced the availability of Nginx Plus, a fully supported version of the server program. This new version comes not only with professional support services, which have been available since February 2012, but with additional features. The commercial version has been developed and supported by Nginx’s core engineering team and is available on a subscription basis starting at $1,350 per instance per year.

Honestly, you can’t. No one can.

So how can you find the right Linux for you? This handy, dandy guide will help
