IDC's newest survey of server vendors shows boxes running every kind of operating system -- except Unix -- sold more during the last three months of 2010. Sales of Linux servers rose 29 percent; Windows rose 16.8 percent, but most surprisingly, sales of mainframes shot up 69 percent â€" the highest growth rate IDC ever found on mainframes.

"Linux isn't Unix, it is rather a written-from-scratch independent implementation...
Yes Linux was written from scratch, so is Solaris or AIX or HP-UX or even *BSD. All of them are Unix! "
No, Solaris or AIX or HP-UX and even *BSD were not written from scratch. They all inherited an existing codebase that came before them, they are all "forks" of an earlier version of Unix. They are all Unix.
Only Linux, and the original Unix itself, were written from scratch.
Linux is not Unix. There is not one line of Unix source code in Linux. Linux was written from scratch, by Linus Torvalds.
Like so:
http://en.wikipedia.org/wiki/File:Unix_history.svg
In this figure, solid lines entering from the left represent existing source code.
Do you understand now?
PS: BTW, the GNU/Linux OS uses GNU (and GNU was written from scratch, by Richard Stallman), but the Linux kernel itself does not use GNU, so the Linux kernel was also written from scratch. Android uses the Linux kernel, but it does not use GNU AFAIK.
GNU is also not Unix. In fact, the very abbreviation, GNU, satnds for GNU is Not Unix.
http://en.wikipedia.org/wiki/GNU
"GNU is a recursive acronym for "GNU's Not Unix!", chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code."

Linux is not Unix. Period.
It's not based on Unix code, it's not Unix certified. It's not Unix.
AIX, HP-UX and BSD all share a common heritage which Linux does not.
In fact, Linux wasn't even intended to be a Unix clone. Originally it was a Minix clone (which also is not Unix).
So anyone who tells you that Linux is any way related to Unix (beyond architecture similarities) is simply WRONG.

Linux was not intended to be a clone of Minix. Minix is a microkernel design, Linux is not, it is a monolithic kernel. They are fundamentally different designs.
http://en.wikipedia.org/wiki/Minix#MINIX_and_Linux
The design principles Tanenbaum applied to MINIX greatly influenced the design decisions Linus Torvalds applied in the creation of the Linux kernel. Torvalds used and appreciated MINIX, but his design deviated from the MINIX architecture in significant ways, most notably by employing a monolithic kernel instead of a microkernel. This was famously disapproved of by Tanenbaum in the Tanenbaum–Torvalds debate.
This more detailed picture purports to show the Evolution of Unix and Unix-like systems:
http://upload.wikimedia.org/wikipedia/commons/5/50/Unix_history-sim...
Minux and Linux are shown on the left, neither of them inherit any code from any lines of Unix development, nor from each other.
Minux and Linux are Unix-like systems, but they are NOT Unix.
Minix is Minix.
Linux is Linux.
Neither is Unix, or derived from Unix.

Linux is a clean-room clone of Minix. There was never any UNIX code in Linux. It's is the bastard step-child of UNIX' distant cousin Minix. No actual blood relation; no actual code history.
BSD is a continuation of AT&T UNIX source code, with a bunch of extra features added in. By the year 1992, there was no original AT&T UNIX code in BSD anymore, but the history is still there, and you can trace back through the CVS commit logs back to the original UNIX sources.
While none of the free implementations of BSD have paid the exorbitant fees to go through the certification process and thus none can call themselves UNIX(tm), they are most definitely Unix-based systems.
MacOS X is a crazy hibrid of NeXT, FreeBSD, NetBSD, and Mach, giving it direct links into the UNIX source code lineage. And, Apple has paid for specific versions to go through the certification process. Thus, it is also UNIX(tm).
But there is no way, no how, none possible, for Linux to be considered UNIX(tm), or even Unix-based, or even Unix-compatible.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »
