Submission + - How Apple will convert HFS to ZFS (storagemojo.com)

Submitted by
An anonymous reader writes: The biggest problem with a new file system like ZFS is the conversion. Backup and restore? I don't think so. StorageMojo has a quick overview of the recent Apple patent application "Converting file-systems that organize and store data for computing systems". You don't move the files, you just change out the file system underneath them. Very neat.

The money quote:

The converter reads the existing file system to find out where all the files are on disk. Then it creates a new set of data structures, such as a catalog and file extents, for the new file system. After verifying the new data structures, the converter can then replace the first file system by modifying the disk's partition map and and overwriting the volume headers of the first file system.
The patent talks about embedding the converter in iTunes, but StorageMojo speculates Apple may be playing a deeper game to ultimately challenge Windows on non-Apple hardware.

Submission + - SCM wars, take two

One week after posting about Linus and his speech on SCM, the folks at Codice Sofware, a start-up company developing from scratch a new version control system written in Mono, claim to have the best branch and merge mechanism compared to systems like Subversion, Clearcase and the like.

Which one is the best SCM for parallel development? Is really Subversion the one to go for or it is taking too long to evolve comparing to other systems?

I've tried Plastic SCM and it looks like a good option but, wouldn't it be better were it be Open Source? Which makes me think: is there any real opportunity for a start-up company targeting a complex business like SCM outside OSS? Is there a better way to reach the market than through open source?

According to Forrester Perforce and SVN are the leaders in the SCM marketplace, just targeting version control, and big players take on SCCM (Software Configuration and Change Management). But at the end of the day, which is the one dealing better with complex day-to-day problems like branching, merging, performance and so on?

Submission + - Fiber Backbone

Submitted by Abe460
Abe460 writes: I live in the sticks and cannot get broadband by any means other than satellite. If this is my only option then I guess I'm limited. I'm pretty sure I already know the answer, but I must ask. Is there any way to get service from a fiber backbone without going through one of their POP locations. The reason for this question is the almost 2000ft of fiber buried under my property belonging to Wiltel. Even if I was to donate some property to an isp company to put in some kind of switch close enough to serve the area I would consider. Life without broadband is almost too much to handle.
