Employees of Lawrence Livermore National Laboratory have ported Sun's/Oracle's ZFS natively to Linux. Linux already had a ZFS port in userspace via FUSE, since license incompatibilities between the CDDL and GPL prevent ZFS from becoming part of the Linux kernel. This project solves the licensing issue by distributing ZFS as a separate kernel module users will have to download and build for themselves.

"I'm pretty sure btrfs will already have matured quiet nicely."
Are you mad? It takes decades to iron out all bugs in a filesystem! ZFS has a dedicated team of among the best engineers in the world, and the test suite is very diligent. ZFS has been developed for years and is well tested. There are still some minor bugs, even 5 years after release. Sun has extensive Enterprise experience and know all about Enterprise storage.
If you really expect BTRFS, developed by some amateurs with no experience of Enterprise storage customers, to be stable at once - you are uneducated. Go and learn how to program. It will take decades to get it stable, just like ZFS. And Sun will not rest, ZFS develops in a rapid pace.
BTRFS is just a ZFS wanna-be. ZFS will add functionality, only afterwards BTRFS will mimic ZFS. BTRFS will never catch up. It is like Mac OS X and Win7

We are currently starting to see btrfs (also developed by Oracle btw ;-) gaining traction.
ZFS seems to be the betamax of file systems already.
ZFS seems to be the betamax of file systems already.
Are you actually going to elaborate on that point or just leave it there in what some might view as a tolling argument?
Aside for better Linux support - I've not seen anything in BtrFS that's swayed my to switch from ZFS.
But I'm completely open to reason, so please explain away

" I do agree with the first poster, and these are my points: ZFS and BTRFS are very similar feature wise, but BTRFS is achieving a lot of attention and support from the Linux community (and some first appearence on the "enterprise" side with RHEL 6 as an "experimental" feature).
So, I'll guess that BTRFS will be accepted as a solid and reliable solution soon, while ZFS will be a lot behind.
So, who will need ZFS when it doesn't provide anything different from BTRFS and not being at the same production-level quality?
(note that this is a question, not a statement! if someone has good reasons to say that ZFS is better, than I'm open to hear it!)

The fact that zfs has no sane Linux support (and possibly never will have) makes it like betamax - it's probably reasonably good technology, but it's not something you have access to in the first place, unless you switch to Solaris. And, I don't think that's the way the tide of the world is turning these days.

btrfs doesn't support pooled storage.
btrfs doesn't support RAID levels above 1 (RAID10 is not higher than 1).
btrfs doesn't do end-to-end checksumming and self-healing.
btrfs doesn't do encryption (still an experimental feature in ZFS, but it's being worked on).
btrfs doesn't do deduplication.
Those are just some things I can think of off the top of my head. There's bound to be a lot more, considering the relative immaturity of the btrfs codebase compared to the ZFS codebase.
IOW, btrfs is where ZFS was 10 years ago. Explain to me again how btrfs is so much better, and will rule the storage world?

One of the ZFS features I think is coolest is L2ARC which let you put a fast SSD as a read/write-cache in front of a pool of slower mechanical disks. The blocks you use most frequently will have a copy on the SSD for quick access. IIRC the cache currently doesn't survive a reboot though (it will start caching from scratch again), but they are working on fixing that.

"This is my NeXTstation Turbo Color booting the Mac System 7.1 Operating System using a hardware add-on called 'Daydream'. The Daydream has a Mac ROM and a few custom ICs in it and hooked up to the NeXTs DSP port. Turns your NeXT into a full fledged 68k powered Mac." So cool.

"The NetBSD Project is pleased to announce NetBSD 6.1, the first feature update of the NetBSD 6 release branch. It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements. Please note that all fixes in the prior security/bugfix updates (NetBSD 6.0.1 and 6.0.2) are also in 6.1."

"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.More News »
