Winners and Losers in Business Open-Source Software

We all know that Linux, Apache and Samba are vital for business data center servers, Web servers and file and print servers respectively in businesses both large and small. What you may not know though what’s trending below the top-tier of open-source software. That’s where OpenLogic, an enterprise open-source software provider and consultants comes in. In their recent study 2011 Open Source Adoption Trending Report, OpenLogic looks at the winners and losers in open-source software adoption.

According to the company’s analysis, the fastest growing open-source projects from 2010 to 2011 in terms of business adoption were:

802.11ac: Gigabit Wi-Fi Devices will be shipping in 2012

To network equipment we used to drag yellow cable about the size and flexibility of garden hose through buildings’ plenum spaces. It was an ugly job. It got better. Then, we got wireless networking and setting up networks got much easier. Still, physical networking usually delivered faster speeds than Wi-Fi networking. Now, things are changing. Broadcom is promising us that the first 801.11ac chipsets will bring us Gigabit wireless speeds without any cables at all.

Mind you, 802.11ac is still a standard in the making. Still, that hasn’t stopped Broadcom from announcing that it’s building 802.11ac chipsets, under the trademark name 5G WiFi, that will be “three times faster and up to six times more power efficient than equivalent 802.11n solutions.” How fast is that? Rahul Patel, Broadcom’s VP of mobile and wireless, promises that their implementation of 802.11ac will be able to deliver speeds of up to 1.3 Gigabits per second (Gbps). Now, that’s fast!

Microsoft is finally making good products — but it’s too late

you’ve read many of my articles over the past 20 years, you may have noticed that I don’t care for Microsoft or its products. That isn’t because I think open-source software or Apple products are unbeatably great. It’s because Microsoft’s products are usually awful.

A lot of you are thinking I can’t possibly be right about that. After all, you work and play with Windows, Office and other Microsoft offerings every day. You’re hardly in the minority. But has Microsoft enjoyed its enviable market position because it produced the best products? Nah.

Microsoft became No. 1 because, in business, Bill Gates had the morals of a great white shark in a feeding frenzy. By the time the courts finally slapped Microsoft down in the Netscape case, it was too late. The great monopolist had either killed off or bought out its competition.

TV for Human Beings: Ubuntu Linux

Ubuntu Linux fans will recognize this story’s title as a play on the operating system’s slogan: Ubuntu: Linux for human beings. Now, Canonical, Ubuntu’s parent company, is taking on Apple and Google by trying to make Ubuntu the operating system of choice for all-in-one Internet, cable, and satellite TV: Ubuntu TV.

According to Jane Silber, Canonical’s CEO Ubuntu TV is not an attempt to bring a Linux desktop to your TV or just put a browser on your TV. Instead, the idea is to use Ubuntu GNOME-based Unity interface as the universal interface.

I can see this. I’ve long thought that Unity, while an OK desktop for non-power desktop users had great potential for tablets, smartphones, and, yes, now TVs.

NGINX takes 2nd place in Web Servers from Microsoft IIS

If you know anything about Web servers, you know that open-source Apache is the number one Web server in the world by a wide margin. You also know that Microsoft’s Internet Information Services (IIS) is the number two Web server. As of the end of 2011, though, you’d also be wrong about second place. The number two active Web server, according to Netcraft, the leading Web server analytics company, is now NGINX.

NGINX, pronounced Engine-X, if you don’t know it, is an open-source Web and reverse proxy server and e-mail proxy server to boot. It’s has been used for years on many popular Russian Web sites such as Yandex, Vkontakte, and Rambler. In recent years, it’s been picked up by major Western sites including Facebook and WordPress.com.

These Web sites, and millions of others, have moved to NGINX because it’s very fast and uses few system resources. The company has claimed that NGINX can deliver 10 times the performance of the leading Web server on the same hardware. I’m not sure about that but I do know it’s faster than Apache or IIS. NGINX manages this by being event-based. So, it doesn’t spawn new processes or threads for each Web page request. That means that even as the Web server load increases, memory use remains low and predictable.

Fedora, Mint, openSUSE, Ubuntu: Which Linux desktop is for you?

There are more interesting Linux desktop distributions to choose from than ever before. However, if you’re looking for major distros with a great deal of support, you’ll want to look at the big four: Fedora, Mint, openSUSE, and Ubuntu.

Each has its own outlook and methods. Thanks to Linux’s customizability, you could take any of them and completely revamp it, if you wish. But unless your idea of a good time is operating system hacking, chances are you’ll want a distribution that already meets your needs.

Three of the four — Fedora, Mint, and Ubuntu — use GNOME as their default desktop interface, although they use it in very different ways. OpenSUSE, on the other hand, uses KDE for its default interface.

Both GNOME and KDE have moved away from their early days when their interfaces resembled that of Windows XP. Each now tries to integrate all available resources and programs, bot
