SGI Compares Linux & System V Source Code

mrgoatCEO writes "It seems SGI has finished up their test comparing SCO's Unix System V code and that of the Linux Kernel, according to ITWorld. SGI found that any similarities between the systems (amounting to only about 200 lines of code) have been removed in Linux Kernel 2.4.22, and added that the similarities were 'trivial in amount.'" This follows moves by SCO to terminate SGI's Unix license.

I don't think they'll get to the GPL issue. It will be like the old ATT case, where the court determined that the plaintiff did not have a valid copyright interest in the code in question, and the case ended there.

Re:Hmmm, 200 lines out of millions

"Copyright law allows for reasonable copying, e.g., a few pages from a book. So surely 200 lines of code out of millions would simply be laughed out of court?

This is profoundly wrong. Copyright law does not allow you to copy a few pages out of a book. It allows you to make Fair Use of copyrighted material. It may be fair use for you to copy an entire book. It may not be fair use for you to copy a single paragraph. There is no "use X many free" formula. People get in trouble believing this.

Re:reminder about shares

"Monninkhof tried to reason with SCO, but didn't succeed. At first SCO agreed to talk, so Monninkhof flew to SCO's headquarters in Utah, but learned that there was no-one to meet him and that visitors were not allowed in the building. Security then escorted Monninkhof off the premises. He was also given a letter indicating that his company was no longer welcome at SCO Forum."

If there was any doubt about the kind of people running SCO these days, this should clinch it. Damn cold..

For the lazy, since June 20 it looks like they have sold shares for a total amount of $2,747,819

Shifting names

[mcc]

Originally SCO stood for "Santa Cruz Operation".

Eventually, SCO sold off its OS division, the one that made SCO UNIX and coincidentally happened at the time to own the original Unix copyrights (having bought them from Novell in 1995), to Caldera, a linux company. The remainder of what used to be SCO, the part Caldera didn't buy, is still operating under the name Tarantella.

Caldera, after buying SCO UNIX, changed its name to "The SCO Group." SCO doesn't stand for anything here. It's just "The SCO Group". Shortly after this the company's co-founder, Ransom Love, was replaced as CEO by Darl McBride, and SCO began to serve the Wyrm.

"The SCO Group" is owned by and has since Caldera's inception basically been under the auspices of an umbrella corporation called the Canopy Group. It has been repeatedly theorized that somewhere about the time McBride came in, the Canopy Group gave up on ever making any money ever again on Caldera's projects. Now, goes the theory, the Canopy Group is using the SCO group for no purpose other than as a front/shell company, so that the Canopy Group can engage in illegal but profitable enterprises such as slander, barratry, and fraud, and then when all hell breaks loose as a result and the countersuits start rolling in, "the SCO Group" gets all the blame and takes all the damage and quietly goes bankrupt, and the Canopy Group walks away scot-free.

That's not going to happen; at least, not with a sane defendent.

We're talking SCO here; so what's your point?

On a more serious note, a poster to GROKLAW ran across this SCO product brochure from 2002 which points out that the very features that SCO says infringe on their intellectual property (XFS, JFS, NUMA, etc.) are selling points in SCO's version of Linux. This makes it kind of hard for SCO to claim that they didn't know these features had been included in Linux and their release of the code under the GPL doesn't constitute GPLing the code.

I could be wrong but this only leaves SCO with three choices:

1. They can't complain about the features, just individual code fragments. They have just told SGI that fixing the individual code fragments isn't sufficient.
2. They challenge the GPL.
3. Drop the suits against IBM and SGI and watch their stock tank.
