SCO gets it Day in Court

Years into its legal wars against Linux, SCO gets another chance to go to court on April 28th. However, the case at hand, one last attempt to show that it, and not Novell, owns Unix’s copyright isn’t the case, SCO wanted. Instead of threatening the legality of Linux, this four-day trial will only determine whether the hot water SCO is in is boiling or scalding.

Shuttleworth Acknowledges Ubuntu’s Debt to Debian

New comers to Linux sometimes think that Ubuntu sprang forth from Linux as a totally new creation, the next generation of Linux. Old-hands at Linux know better. Now, Mark Shuttleworth, CEO of Canonical, the company behind Ubuntu, sets the story straight for those to whom Ubuntu 8.04 is the be-all and end-all of Linux.

In his latest blog posting, Shuttleworth once more acknowledges the debt Ubuntu owes to other open-source developers and projects. After opening by thanking the Ubuntu community, Shuttleworth moved on to thanking the larger free software world.

Shuttleworth wrote, “I’m very conscious of the fact that Ubuntu is the pointy edge of a very large wedge – we are the conduit, but we exist only because of the extraordinary dedication and effort of thousands of other communities and projects.”

In particular, “We all owe a great deal to the team who make Debian’s ‘unstable’ repository possible, and of course to the upstream projects from GNOME and KDE through to the Linux kernel. We hope you will be proud of the condition in which we have carried your excellent work through to the users of Ubuntu.”

Vista Network Speed-Up Tip

I hate Vista, but since one of the things I do is track operating systems, I keep it running on one (1) system.

One of the things I find remarkably disagreeable about this junker of an operating system is that its network software is just awful. For example, it took me quite a lot of digging before I found a way to get Vista to work at all with most NAS (Network Attached Storage) devices.

An eternal problem with Vista, and one I’m not alone in finding, is that it’s slower than the guy in the left-hand lane who doesn’t understand the concept of ‘passing’ when it comes to transferring files across my network. How slow as it? There were times, on a 100Mbps connection when I was averaging a MB transferred ever 7 seconds. That would be great, if I were transferring files over my 3Mbps DSL Internet connection, it’s horrible on a LAN.

I had hoped that Vista SP1 would solve this problem. It didn’t.

CAPTCHA Meltdown

It seems like it was the just the other day that I was writing about how CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) was quickly becoming completely useless for Web security. Actually, it was just the other day-two days ago-but I was wrong. CAPTCHA is already completely useless.

I found the proof of this in the Web security company WebSense’s Sumeet Prasad, a threat analyst, latest blog. There, he declared that there’s now a botnet-based program that can beat Google’s Blogger CAPTCHA.

The program’s not terribly good at breaking Blogger’s CAPTCHA. WebSense estimates it has an 8% to 13% success rate and it takes about 35-seconds per attempt. But, with hundreds to thousands of zombied home PCs doing nothing but trying to create fake blogs, the program doesn’t have to be very good at it.

Sorry, I’m not feeling social today

Please. I don’t want to Link In with you today. I don’t want to see your Face, or read your Book. It’s not that I don’t like you. I do. I’d Twitter with you anytime. It’s just that if I get asked to join one more social network, I’m going to scream.

You wouldn’t like that. I wouldn’t like that.

I get social networking. I really do. I’ve been a member of online communities since the 80s. I’ve managed mailing lists using LISTSERV and Mailman; supervised online discussion groups on CompuServe; and I use LinkedIn and Facebook on a regular basis. I’m also on, but almost never use, Plaxo; Twitter and half-a-dozen others that I don’t even recall joining.

These networks have been invaluable to me over the years for maintaining friendships over thousands of miles and years of time; finding both freelance and fulltime work; and sharing good times and bad times with those who are near and dear to me. So, please understand me when I say, in the nicest possible way, “Enough is enough! Do not; do not ask me to join another social network!”

OLPC: It’s about the Kids, not Open Source

People have been in a tizzy over recent executive changes at the OLPC (One Laptop per Child) project, but its founder, Nicholas Negroponte, in an e-mail to the group’s members on April 23rd wrote, “As we reach out to engage a wider community, some purism has to morph into pragmatism.”

Things started heating up at OLPC when Walter Bender, the former president of software and content, was first moved to the job of director of deployment. This was seen by some, such as OLPC Director of Security Ivan Krsti, as a demotion. Because of this, and what Krsti saw, as he described in his blog as “a drastic internal restructuring coupled with what, despite official claims to the contrary, is a radical change in its goals and vision,” Krsti resigned from OLPC in mid-March.
