Linux Foundation launches major open-source license compliance program

BOSTON, Mass. — The Linux Foundation, the non-profit organization dedicated to supporting Linux, announced on Aug. 10 at LinuxCon the launch of the Open Compliance Program, a comprehensive initiative to help companies and developers comply with open-source licenses.

You may not know it, but getting businesses and developers to obey open-source licenses has become a much bigger problem over the years. I’m not talking about the differences between GPLv2 and GPLv3. I’m talking about companies using open-source code and not realizing that they can’t just use it any way they want.

This has become a problem because almost every major company is now using Linux and open-source software. That’s both the good and bad news. With so many companies using and, more important, incorporating free and open-source software (FOSS) in their products, there’s lots of room for businesses to make big mistakes.

That’s especially true in the mobile and consumer electronics space. All you have to do is look at the legal record and you can see that. Company after company builds some neat device and uses FOSS but then doesn’t bother to follow the rules on how the software should be used. Then, when they’re caught at it, the Software Freedom Law Center (SFLC) or a private law firm comes down like a ton of bricks on the open-source license violators, and they have to pay for their sins.

The Corporation has gone Open Source

While Microsoft and friends are doing their best to hide Linux and open-source software from the public, businesses have been adopting Linux and open-source faster than ever. That’s not the opinion of FOSS (free and open-source software) fans. That’s what Accenture, a global management consulting, technology services and outsourcing company with no particular love for FOSS found in its survey of 300 large private and public organizations.

Accenture “found that half of the respondents (50 percent) are fully committed to open source in their business while almost a third (28 percent) say they are experimenting with open source and keeping an open mind to using it. Furthermore, two-thirds of all respondents (65 percent) noted that they have a fully documented strategic approach for using open source in their business, while another third (32 percent) are developing a strategic plan. Of the organizations using open source, almost nine out of ten (88 percent) will increase their investment in the software in 2010 compared to 2009.”

In short, to quote, Accenture’s chief technology architect Paul Daugherty, “What we are seeing is the coming of age of open source. Through both our research and our work with clients, we are seeing an increase in demand for open source based on quality, reliability and speed, not just cost savings.”

Digg, dug, buried: Linux

A liberal blogger has uncovered that a “group of influential conservative members of the behemoth social media site Digg.com has just been caught red-handed in a widespread campaign of censorship, having multiple accounts, up-vote padding, and deliberately trying to ban progressives.” The blogger, Ole Ole Olson, infiltrated a group that called itself Digg Patriots. His proof is quite damning.

Those of us who follow Digg have long known that Digg has long been susceptible to external gaming. While Digg’s leader Kevin Rose has tried to keep this type of thing from happening, the company’s biggest efforts to clean up its social bookmarking system have ended up vexing some of its biggest fans. In the meantime, as Digg Patriots has shown, Digg’s popularity contest for stories remains easy to corrupt.

I strongly suspect, although I am not able to prove as Olson has, that other groups use similar techniques to ensure that stories about technologies they hate, like Linux, almost never become popular. In turn, this means far fewer people will ever see stories about Linux. Friends who also write regularly about Linux and open source tell me they see this happening.

In early 2009, new popular Linux stories would pop up every day or two on Digg. By mid-2010, Linux stories on Digg became popular only once every week or so. Why? Has everyone who once interested in Linux suddenly vanished? Have people stopped writing about Linux? I don’t think so.

The only explanation I can come up with is that Linux stories are getting down-voted on a regular basis on Digg these days. Who’s doing this? In whose best interest is it to make it appear that there’s little interest in Linux? Might it be a company named Microsoft?

Microsoft’s FUD war against Linux never ended. Microsoft’s long-discredited patent claims against Linux still appear from time to time. Most recently, they’ve shown up in attacks against Android.

I doubt that Microsoft is doing this directly. But Microsoft has fans who are happy to attack Linux every chance they get.

For example, until we started stronger moderation of the Computerworld’s blog comments, I could count on several anti-Linux trolls showing up within minutes. The story didn’t need to have anything to do with Linux, and — ta-da — there would be several notes saying “Linux is awful. Why do you keep writing about this crap?”

Coincidence? I don’t think so. I find it hard to believe that J. Random Person is immediately going to attack virtually every Linux story that appears. I find it easy to believe that Microsoft “fan boys,” and yes they exist, are happy to spread the impression that Linux is awful and that its supporters are dumb.

Would these same people do their best to make sure that Linux is buried on social bookmarking sites like Digg, Reddit, and StumbleUpon? Why, yes, I believe they would. And, more to the point, I believe they have.

A version of Digg, dug, buried: Linux first appeared in ComputerWorld.

Naked Pictures!

The government has assured us that the images made from “Digital Strip Search”” imaging technologies like millimeter wave and backscatter imaging wouldn’t be saved. They lied. It turns out the U.S. Marshals Service saved more than 35,000 “whole body” images of people who entered a U.S. courthouse in Orlando, Fla.

And, if the U.S. Marshals Service can do this, why should we trust the Transportation Security Administration (TSA) to keep their word about deleting these images? I can’t think of any good reason, can you?

Oh, I’m sure the TSA policy will be to delete the images … except for, oh I don’t know, if they do think they spot a bomb on someone. Then, they’d want to keep the image in case in the resulting search there’s a rumpus and the passenger sues them for an unreasonable search. Or, say some near-minimum-wage TSA contractor thinks you’re really hot and wants to keep your naked image as a keepsake. Or, he or she thinks your x-ray unclad photo is hilarious and wants to share it with their buddies on Facebook. You get the idea.

Wave fails, Twitter wins. Why?

I was one of those lucky people given early admission to Google Wave. There was only one problem. Once we had Google Wave, we couldn’t figure out what to do with it. And if we, a bunch of techno-geeks and technology journalists, couldn’t come up with a good use for Wave, what chance did anyone else have? So it came as no surprise when I learned today that Google is pulling the plug on Wave.

I never met anyone who found a real use for Wave. They instead found IM (instant messaging), wikis, Google Docs, Lotus Notes, or, heck, good old-fashioned e-mail lists do a better job at helping them work in groups.

It’s been months since I’ve used Google Wave, so I’m not going to miss it — is anyone? But I wonder why some ideas that sound good, like Wave, fail, while others that sound silly, like Twitter, take off.

How to get Windows and Linux to cooperate on the network

“East is East, and West is West, and never the twain shall meet,” is a line from Rudyard Kipling’s The Ballad of East and West. It could also apply to Windows and Linux. If you don’t know what you’re doing, getting the two to meet on the network can seem like it’s almost impossible. Fortunately, it has gotten easier over time.

It’s not a job though for an average Linux administrator or a Windows Microsoft Certified Systems Engineer (MCSE) who’s still wet behind the ears. While parts of it, such as sharing files and printers across a network between Windows and Linux systems, are simple enough, bridging the gap between Active Directory (AD) and Lightweight Directory Access Protocol (LDAP) requires some serious network engineering.

The first part, simply sharing files and printers, can be handled by using Samba as a server or as a client on Linux and Mac desktops. Samba is an open-source program that provides Server Message Block/Common Internet File System (SMB/CIFS) file services. With Samba, your Linux servers can act just like Windows file and printer servers to all your desktop clients. Whether your PCs run Windows 7, XP, Mac OS X, Snow Leopard, or Ubuntu, Samba can get the files to them whenever they need them without much fuss or muss.

But, once you start trying to manage logins and authentication between Linux and Windows systems with just AD or by combining LDAP and AD, things can get complicated. One way to handle this is just not to use AD at all. I know, I know, that’s heresy to Windows administrators. But, for small to medium business networks, an LDAP implementation such as OpenLDAP may be all you need for both Windows and Linux servers and desktops. If you need more, there are other network directories that can work for both operating systems that come with enterprise-level support such as Novell’s eDirectory.
