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

Firefox wants to be your business buddy Web browser again

Mozilla, the group behind the Firefox Web browser, has finally gotten a clue that business users don’t like constant updates. On the Mozilla wiki page, Mozilla admits to what many of us have known for a long time: Firefox’s recent rapid-fire release schedule was way too fast for corporate and institutional users. On the page, Mozilla states:

The shift to a new release process has been difficult for organizations that deploy Firefox to their users in a managed environment. We’ve heard 2 primary concerns:

1. The release schedule doesn’t allow sufficient time for the organizations and their vendors to certify new releases of the products.

2. The associated end-of-life policy exposes them to considerable security risk if they remain on a non-current version past Firefox 3.6.

These groups-which include small & medium business, enterprise, academic, and government-want to continue to offer Mozilla products to their users, but they need a version of Firefox that gives them a longer support tail than what we currently offer.

You think!?

NASA opens it Open-Source Code Doors

Back in the 1980s, I was writing open-source programs for NASA. Oh, we didn’t call it open source then. Open source as a term wouldn’t exist until 1998. All the code we produced was “free software,” but we didn’t call it that either. We just made the best code we could and shared it with people. It was a different time. Many of these programs were made available under the COSMIC software project. Today, NASA is centralizing its open-source offerings at the Code NASA Web-site.

The idea of this new Web-site is to “continue, unify, and expand NASA’s open source activities. The site will serve to surface existing projects, provide a forum for discussing projects and processes, and guide internal and external groups in open development, release, and contribution.” That’s all for the best since, while NASA started formally supporting open-source software in 2003, those efforts have usually not been very co-ordinated.

As William Eshagh, who is spearheading the project wrote on the NASA open-source blog, NASA is first “focusing on providing a home for the current state of open source at the Agency. This includes guidance on how to engage the open source process, points of contact, and a directory of existing projects.”

Should Amazon, Google & Wikipedia “nuke” the Web to stop SOPA?

With the Stop Online Piracy Act (SOPA), Congress, at the request of big media, is still considering trying to censor the global Internet in the name of preventing media piracy The major Internet companies, who don’t like the idea of being forced to monitor customers’ traffic and block Web sites suspected or accused of copyright infringement. They don’t want any part of being in the Big Brother business. So it is that Google, Amazon, Facebook, Twitter, and Wikipedia appear to all be considering the ‘nuclear’ option.

According to multiple sources, the nuclear option would mean many major sites would simply and simultaneously go dark. Were you to go to any of them, you’d either find a 404 error page not available message or a page explaining why the site’s currently unavailable. The most popular Internet sites would simply go dark.

This is pretty drastic, but then so is SOPA. SOPA, while a proposed American law, attempts to censor sites throughout the world. In effect, as it’s currently written, SOPA would try to impose global censorship almost as bad as the Chinese firewall.
