    The problem is... Professional developers are paid to scratch someone else's itch. Hobby developers are often trying to scrach their own itch. But... Hobby developers are not being pushed to meet someone else's requirements. Then again, it might be because all the good ones have been hired up and have no free time to do anything outside work.

  7. Re:WORM: write once, read many on Anti-static Polymer Stores Data, Too · · Score: 5, Interesting

    Plan 9 in particular uses WORM media for long term storage and as a form of versioning - it uses magnetic rotating disk platters for level-2 caching and volatile RAM for level-1 caching.

    From http://plan9.bell-labs.com/sys/doc/9.html :
    "The file server has three levels of storage. The central server in our installation has about 100 megabytes of memory buffers, 27 gigabytes of magnetic disks, and 350 gigabytes of bulk storage in a write-once-read-many (WORM) jukebox. The disk is a cache for the WORM and the memory is a cache for the disk; each is much faster, and sees about an order of magnitude more traffic, than the level it caches. The addressable data in the file system can be larger than the size of the magnetic disks, because they are only a cache; our main file server has about 40 gigabytes of active storage.

    The most unusual feature of the file server comes from its use of a WORM device for stable storage. Every morning at 5 o'clock, a dump of the file system occurs automatically. The file system is frozen and all blocks modified since the last dump are queued to be written to the WORM. Once the blocks are queued, service is restored and the read-only root of the dumped file system appears in a hierarchy of all dumps ever taken, named by its date. For example, the directory /n/dump/1995/0315 is the root directory of an image of the file system as it appeared in the early morning of March 15, 1995. It takes a few minutes to queue the blocks, but the process to copy blocks to the WORM, which runs in the background, may take hours.

    There are two ways the dump file system is used. The first is by the users themselves, who can browse the dump file system directly or attach pieces of it to their name space. For example, to track down a bug, it is straightforward to try the compiler from three months ago or to link a program with yesterday's library. With daily snapshots of all files, it is easy to find when a particular change was made or what changes were made on a particular date. People feel free to make large speculative changes to files in the knowledge that they can be backed out with a single copy command. There is no backup system as such; instead, because the dump is in the file name space, backup problems can be solved with standard tools such as cp, ls, grep, and diff.

    The other (very rare) use is complete system backup. In the event of disaster, the active file system can be initialized from any dump by clearing the disk cache and setting the root of the active file system to be a copy of the dumped root. Although easy to do, this is not to be taken lightly: besides losing any change made after the date of the dump, this recovery method results in a very slow system. The cache must be reloaded from WORM, which is much slower than magnetic disks. The file system takes a few days to reload the working set and regain its full performance.

    Access permissions of files in the dump are the same as they were when the dump was made. Normal utilities have normal permissions in the dump without any special arrangement. The dump file system is read-only, though, which means that files in the dump cannot be written regardless of their permission bits; in fact, since directories are part of the read-only structure, even the permissions cannot be changed.

    Once a file is written to WORM, it cannot be removed, so our users never see ``please clean up your files'' messages and there is no df command. We regard the WORM jukebox as an unlimited resource. The only issue is how long it will take to fill. Our WORM has served a community of about 50 users for five years and has absorbed daily dumps, consuming a total of 65% of the storage in the jukebox. In that time, the manufacturer has improved the technology, doubling the capacity of the individual disks. If we were to upgrade to the new media, we would have more free space than in the original empty jukebox. Technology has created storage faster than we can use it. "

    What it really means is that the work is not in the public domain, furthermore, it means that you don't have copyright for that piece of work.
