The only FS that uses an append-only log structure for both data and metadata is Margo Setzer's defunct LFS developed under 4.3 BSD. [Xj]fs are journalling, not logging, filesystems. The "j" kind of gives it away.
"Sun began when BSD (renamed SunOS by an infant Sun Microsystems) became fairly stable and added IP networking to the kernel."
The internet protocol stack was added by Bolt, Beranek and Newman to pure 4.3BSD. BB&N were working under an ARPAnet grant. This was the original and definitive TCP/IP implementation.
Research has been underway for a few years on the "protein drive." The operative principle is a photosensitive protein which occurs naturally in swamps. I believe that it darkens upon exposure to light to cause the (light/dark)-(1/0) memory mechanism. Throughput is proportional to the time required for the protein to respond to the light condition, and storage density is proportional to molecular "resolution" and the energy of the impinging light waves. The storage capacity of the funny-looking-prototypes in the labs in '97 was on the order of 1GB/cm^2. The access time was on the order of 10^-3 s. Improvement should come from tweaking the molecularity of the protein, possibly by mutating the life-forms that produce it (speculation.)
Computer system design is ultimately a vast series of tradeoffs. M$ has, in many cases in the NT kernel, traded stability for speed. That is why NT's uptime numbers are so comical. NTFS is probably just plain better than ext2fs, also. SGI's XFS contribution may alleviate this, however. I estimate that it will be 1 year at the most before Linux wins decisively in all relevant categories.
Men, this is a very important event. Mosix is the Right Thing (tm) and now it has the right license. Life is good. Slackware 3.6 and Mosix source code under GPL. My faith in Humanity just doubled.
Folks, I have seen some cluelessness in my days and believe me, this guy is it. But, lest I indulge in a _purely_ ad hominem rant - to the argument: How, exactly am I supposed to fix Billy's busted M$-Wrong Thing(TM) a) without access to the source, and; b) given that it's a nasty piece of crap at the _design_ level. Winbloze is a scrap-and-redo chunk of excrement. End of story. Keep hacking, people. We have got to make the Right Thing(TM) win just once. It's really really important that our children do not grow up in an M$-dominated planet. Gawd, this article makes me puke.
Not to detract from the considerable cross-examination skills of Mr. Boies, I must say that it is relatively easy to chew these people up due to the fact that they are FLAT OUT LYING. M$'s problem is that they didn't get their stories straight before they went to court. Boies is having a field day with the internal inconsistencies alone.
Is that 5 degrees F or C? As an Illinoisan, I sympathize either way. Minnesotans sympathize if it's C. Alaskans only if it's Kelvins instead of degrees.
