OpenSolaris Code Released
njcoder writes "C|net's news.com.com has reported that Sun Microsystems is releasing parts of the OpenSolaris code today licensed under the OSI-approved CDDL . The release consistes of over 5 million lines of code for the base system OS/Net (kernel and networking). OpenSolaris is based on Solaris 10, the current version of Sun's Unix Operating System. Back in January, Sun released the code for DTrace, a dynamic tracing tool for analyzing and debugging kernel and userland events. DTrace is one of the big features in Solaris 10. Some other highlights include the GRUB bootloader, SMF (Service Management Facility) which replaces init.d scripts, it starts up processes in parallel for faster boots (7 second boot on a dual opteron workstation I think that was the setup) as well as providing features for automatically restarting. OpenSolaris provides support for x86/x86-64 processors as well as Sparc. The Blastware guys are working on Polaris which is an OpenSolaris port to PowerPC. Sun has been working on opening Solaris for over a year now. The OpenSolaris project started with a pilot group of Sun and non-Sun users. During the pilot program a lot of info including screenshots could be found on various OpenSolaris member blogs. (My favorite is Ben Rockwood's blog). Teamware is the source code management system Sun uses for Solaris and OpenSolaris. Which was designed by Larry McVoy (now of BitKeeper) while he was at sun. No word yet on if Teamware will be available for OpenSolaris developers or not. Sun also uses CollabNet for it's Open Source project websites so that might be a possibility as well."
this code is a trap to scuttle linux development. sun will be looking to sue coders who they feel copy concepts and code from opensolaris into gpl'd codebases. do not look at the opensolaris code is you are a linux coder or code in gpl'd software. protect yourself and your code.
if this project is half as successful for sun as openoffice is i'm sure they'll be happy they decided to open it...

"7 second boot on a dual opteron workstation I think that was the setup"
You don't have to think, just RTFA, where you can see that it was a single AMD64 setup.
Still, I guess that would be too much trouble for the simple gain of being correct ?
I believe we are seeing the monopoly finally begin smashed to pieces. Besides the Linux and *BSD alternatives, we now have open-source x86 Solaris at our disposal, as well as the upcoming release of yellowTAB Zeta (based on BeOS). And with Mac OS X coming to the x86, things may really start to get interested. Just as people thought the x86 PC operating system market would start to stagnate, we have all sorts of innovation coming our way!

MS moved to "Shared Source" sometime ago. It was done in hopes that Linux coders would borrow from MS. So far, it has not happened.
But this has potential to do what MS could not. Solaris is at least respected by the development world. This is simply another trap being laid by Sun and MS against Linux.
What is funny is how little ppl seem to remember from just 7 years ago. Sun actually ported to X86 once before AND "opened" their source code. Then when they thought that things were going well, they dropped it. If Sun ever feels like things are going in their favor, it is almost certain that they will do it again.
I prefer the "u" in honour as it seems to be missing these days.
Linux is written in C. When you require a nonlocal exit from a loop without dealing with the overhead of a function or even sentinel variable checks (I usually use "bail"), goto is just the thing. Nothing wrong with forward goto's. Backward gotos to "redo" a loop are kind of icky, but also not wrong.
When "GOTO Considered Harmful" was written, it was THE flow-control structure. Only unthinking idiots actually believe it is never Ever EVER to be used.
Using goto in C++ is an almost universally bad idea if it ever crosses blocks though. Destructors don't get called. Technical reasons like that usually have little to do with "I'm such an engineer, I know goto sucks" attitude.
Does Solaris want to be the hacker's desktop OS? I really doubt it. Does Solaris want to be an OSS player in the data center? Absolutely. And for data center features, Solaris does very well against the competitors. If you think Sun's OSS strategy is to get joe hacker to run his OS, of course you're going to be disappointed, because you just don't get it yourself.
