ZFS gets inline deduplication

One of the file systems out there, IMHO, is ZFS by Sun for Solaris. Sadly, they can't open source it easily because there are portions that can't be licensed under the GPL license. And if they take them out, there isn't much left of the strength of ZFS. Oh well...

Anyway, ZFS gets inline deduplication! This means, that ZFS can decide -on the fly- if a data block was already written by another process at another time and know where that was. It then merely needs to store a pointer to that particular block elsewhere on the disk (an inode) and it's done.
Expensive data center storage solutions such as NetApp and EMC use this technology too, but these boxes cost $100,000+. ZFS is the file system that you use when you format your disks! Any disks! :)

El cheapo RAID with ZFS

CSI: Munich, an integrator from Germany, posted a video on YouTube about building an el cheapo disk array using ZFS. They actually use USB disks instead of real disks, to make it even cheaper. Oh and this won't work in Windows, of course: you can't change the %$@&% file system in Windows (NTFS/FAT only). :P
ZFS is a radically new file system developed for Solaris.

A Comparison of Solaris, Linux, and FreeBSD Kernels

Long ago, 1995, when I had a Java Programming course at Sun in Amersfoort, when we started talking about low-level system implementations such as processes, threads and memory management, I started to be impressed by the Solaris OS. On the low-level aspect of things, it is very well thought out and designed. It isn't VMS of course, :respect:, but I understood why the internet was built on its backs. For network communication it is excellent.
One of most commonly asked questions was: "And how does Windows (NT) do this?" That would result in loud laughter, followed by a deep sigh and a techy explanation at which we the class would repeat the laughter and head shaking. :) But now here's your chance to laugh too...
OpenSolaris has posted a comparison of three *nix subsystems: scheduling, memory management, and file system architecture. It compares these subsystems for Solaris, Linux and FreeBSD. It may be a bit too techy for most of you, but just browsing through it and …

Open Solaris LiveCD

Just a few days the Open Solaris kernel was released to the open source community, they've already made a LiveCD: Project SchilliX. Bare in mind that this the first release, so don't expect a fully working environment yet. However, if you're up for a real OS, one that made Internet to what it is today... get ready and let the CD (178 MB) bootstrap your PC!

RSSOwl - A Java Feed Reader

Image
Looking for a simple, stand-alone feed reader? Don't care about Outlook integration or don't want to pay for it? Fed up with web-based feed readers? Try RSSOwl, which is Java-based and therefore runs on Windows, Mac OS X, Linux and Solaris. Now there's no reason to stay uninformed from anything!

Sun to Roll Out Free Solaris 10

Image
Wired says Sun to Roll Out Free Solaris OS. They expect to make money on the servers and other hardware, not the OS itself. I, personally, am all for this kind of business model. It shows great confidence in your products and the OS will run on over 270 computer platforms, including Sun, Intel and AMD. This way, Solaris kan also compete with OSes like RedHat and other Linux distos.

The SphereXP - the 3D desktop

The SphereXP is a Windows XP implementation of an old idea that Xerox Alto Parc already had back in the late 90s. Why limit yourself to a 2D desktop to keep and organize your icons and windows, when you can 3D and also put windows a bit in the background (literally), when you don't use them for a little while. Or keep all your mail related programs running off to the left and Office windows overhead? :drool:
It's totally cool and extremely unnecessary, and yet I would *love* to have it!!! Of course, Solaris has had its Looking Glass for a while now...

Free Solaris 9 for Intel x86 platform

Image
Slashdot reported that Solaris 8 and 9 are downloadable for free again, for people running the Intel x86 platform. That's good news for geeks and nerds who want to gain experience in working with the platform used by almost all large and self-respecting ISPs out there. Many companies also have it running in their backbones out there...

IBM To Publish Java Office Suite

[Source: Slashdot]
IBM is said to bundle a Java-based server-side Office suite with its web server product and portal WebSphere. With StarOffice, OpenOffice and MSOffice, this now gives you 4 choices for an Office suite on your PC! :) That is not counting Corel's Wordperfect8 for Java, which is said to be a decent alternative for anyone on serious Unix hardware (i.e.Solaris users).
Also, considering that you'd get a free server-side Office suite bundled with a pretty decent webserver and portal software, and therefore save costs for getting MSOffice for all your employees, this might not be such a bad deal. Everything, of course, depends on the suite being able to at least read 95% of existing Office documents... that remains to be seen.
