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.

Going to IPv6 isn’t going to be easy

ecently, I’ve been writing a lot about IPv6, the next generation of the Internet Protocol that makes the Internet and most home and business networks go. Now, like it or lump it, we, starting with our businesses and mobile devices and eventually our home networks, are all going to have to move to IPv6.

That is going to be a major pain, especially for network administrators, but as I’ve been working more with IPv6 I’ve discovered other problems. A lot of network equipment out there can’t actually handle IPv6.

Oh, the vendors may say that it supports IPv6, but the truth is another matter. I’m not going to name names because I’ve been finding this during the course of upgrading my own network infrastructure to IPv6 instead of in a lab. If I had access to a real lab I could spend the time needed to make sure of my conclusions and explain exactly what’s happening.

What I can say though is that there’s a lot of hardware network incompatibilties out there. In the course of using both enterprise and SOHO (small office-home-office) equipment I found that even devices from the same vendor sometimes couldn’t connect using IPv6 with each other. This is not good.

OpenSolaris’ child, Illumos, goes forward without Oracle

Nexenta, an open-source organization that’s been trying to “combine the OpenSolaris kernel with the GNU/Debian user experience,” has announced a new open-source effort called Illumos. Nexenta proclaims this “is a 100% community-driven and -owned effort that aims to provide an alternative to a critical part of the OpenSolaris distribution, freeing it from dependence on Oracle’s good will.”

Oracle’s good will has been noticeably missing towards OpenSolaris. Oracle has essentially ignored OpenSolaris and paid no attention to the OpenSolaris Governing Board. Nexenta observed in their announcement that “Oracle has significantly reduced their support for OpenSolaris as a distribution.” But according to Simon Phipps, Sun’s former chief open-source officer and an Illumos supporter, this effort is not meant to be a fork of OpenSolaris,.

So if it’s not a fork, what is Illumos? In a webinar on August 3, 2010, Garrett D’Amore, the leader of the Illumos project, explained: “Illumos is a derivative, a child of OS/NET, which is Solaris/OpenSolaris’s foundation. The design is to make it 100% application binary interface (ABI)-compliant with OS/NET.” Garrett previously worked on Solaris for Sun and Oracle and is now the senior director of engineering at Nexenta.

While not an operating system distribution in and of itself, Illumos is meant to serve as the basis for distributions. According to D’Amore, it’s also “designed to solve the key problem of OpenSolaris: Not all of OpenSolaris is open source.” For example, the libc_i18n, which is a component needed to build a working C library is essential for C programming in OpenSolaris — and it’s closed source. In addition, the NFS (Network File System) lock mechanism, portions of the cryptography code and numerous critical device driver are not open source.

The bottom line is that, today, you can’t boot either OpenSolaris or Illumos without Oracle’s proprietary bits. D’Amore hopes to have that changed by year’s end.
