P2P gets profitable

Monday, November 22nd, 2004 -- By ET

As predicted in my paper written in 2002 “Stardom, Peer-to-peer and the Socially Optimal Distribution of Music”, P2P could be potentially integrated in a business strategy for the music industry, and bring in profit.

A lot of news stories below:


P2P Tilts Toward Legitimacy


Weed is offering some way (based on DRM implemented by Microsoft) for people to sample music before they want to buy. Here is a story from Wired News.


Here is a Rollingstone article showing how the industry is shift gears, and if you read my 2002 article, you will see how my idea gets integrated in the new trend.

P2P gets profitable

OutKast, Britney, Destiny’s Child to be offered through new P2P service

Two pioneers of file-sharing — Napster’s Shawn Fanning and Grokster’s Wayne Rosso — are quietly working with the major labels to find ways of making peer-to-peer sites profitable.

Mashboxx, a new P2P site started by Rosso, is expected to launch early next year and incorporate new technology developed by Fanning. Called Snocap, it allows users to share music freely but with a catch: When you attempt to trade a protected song, Snocap will swap it with an authorized file — likely a low-quality version of the song or one that lets you listen just a few times. Mashboxx will then provide the option of buying a CD-quality file of the track with a click of the mouse.

Sony BMG is the first major label to embrace the technology, though others are expected to follow. According to a source familiar with negotiations between Sony BMG, Mashboxx and Snocap, the label will offer most of its catalog — which includes music by Bruce Springsteen, Destiny’s Child, OutKast, Britney Spears, Modest Mouse and Bob Dylan — through the service.

It would mark a new era in the relationship between labels and file-sharing sites — a relationship previously “characterized by fear, anger and a desire to take revenge,” according to Josh Bernoff, an Internet analyst at Forrester Research. The Recording Industry Association of America has long held the position that unauthorized use of P2P technology is the major reason for the decline in music-industry revenues in the past three years. Sony BMG CEO Andrew Lack quipped to the New York Times in September 2003 that “P2P stands for piracy to pornography.” But record-label sources say that since taking over Sony early that same year, Lack has been fascinated with the possibility of using P2P as a new way to distribute music.

Mashboxx is actively seeking deals with other labels, though none have yet signed on. Mashboxx users will still be able to freely trade songs from labels that decline to work with Mashboxx, as well as share bootleg recordings the labels don’t sell.

But some observers suggest that P2P users will likely migrate to other sites where Snocap does not operate. “If people want to get legitimate music, there are a huge number of legitimate distribution services they can get it from,” says Bernoff. “If they want to steal music using P2P, then they aren’t interested in paying for it. I can’t figure out who is supposed to use a service like this.”

Harmonics

Monday, November 22nd, 2004 -- By ET

Had a talk with Carlos, and it seems that Harmonics is a good unit of analysis to figure out the “technicalities” of appeals brought about by music. (seems especially so for hip-hop).

harmonics According to a 9th circuit ruling, any derivative music work should get copyright clearance for every note included in the piece before it can be legally published. This creates a huge problem for hip-hop musicians who constantly borrow from previous works. Getting permissions for each and every note could be so cumbersome and ruin the whole hip-hop culture, so a better pricing mechanism is needed for clearing the rights among musicians. Harmonics seems to be a good starting point to study, there is an interesting connection between harmonics and the traditional hedonic model in econometrics. When I have time, I will have a look at this problem, and hopefully, this can evolve into something helpful for the music industry. I will add a few links belows for future research.

The Einstein playing violin picture is taken from Here. It explains the basics of harmonics.
There are a lot of papers about hedonic models:

a few more words about backing up

Monday, November 22nd, 2004 -- By ET

Backing up is very important to me. On my linux server, in the beginning of the HDD, there is a logical error, but I could not fix it no matter what kind of software I use. So I really need to be prepared for a HDD failure. My backing up strategy is as follows:

1. transfer important files from my laptop to the linux server with SyncBack (a free software). I do it with the scheduler in XP, and let it run at 3am each day. (This makes sure that my laptop files are safe). I also use the same software to sync the laptop files with my home desktop. So basically, I have 3 copies of these files, one on laptop, one on desktop and one on the linux server in my office.

2. for important directories on the linux server, e.g. /etc/, /home/, /var/lib/mysql, etc., I do daily backups within the linux server, with rsback, to a secondary harddisk. So if the system disk fails, I still have the copy of configration files, database files, etc.

3. For each of the directories, I do daily rotation for 6 days, then every 7th day, I make a backup to the weekly backup folder. The superiority of rsback over other solutions is that I not only can get back the latest version of the files, but can also get back the files in various states (in XP terminology: snapshots).

4. Just as if the above is not secure enough, I use rsync (enhanced by rsback) to backup the "backup folders" on my linux machine to another linux machine in another building every week for 3 weeks, then save a snapshot every month for 3 months.

When trying to restart apache, the system locked.  So I hard rebooted the machine, and it gives all kinds of weird messages, among which, the most important one is " can not mount root=LABEL=/ duplicate", and I found the problem is related to my second hard drive.  the disk /dev/hda1 has the label of /, and it is conflicting with the system drive’s root at /dev/hdd2, so I used the command "e2label /dev/hda1 /useless" to mark it and rebooted.  This time, it goes on smoothly, except one thing:

It says there is a problem with the hard drive.  Now I’m thinking to get a partition image of the drive just in case it fails some day.  Although I have all the contents backed up, I still think installing the system is a headache, not to mention I have to re-setup all the services I’m so used to use.

To get a partition image, I searched google, and  two solutions come to my attention.  First is called mkCdRec at  http://mkcdrec.ota.be/project/index.html the other is called System Rescue CD http://www.sysresccd.org/index.en.php.

With mkCdRec, I typed "make test" and make and followed the instructions, it created some tar.gz files on a portable hard drive.

And the SysResCD should be booted and it should create some image on a mounted portable drive.  I have yet to test the usability of the two solutions, but mkCdRec is very slow because it called tar to compress the files, and it can take too long.

After I get the image, I’ll "low-level" format the hard drive, and copy the image back, this ensures that the bad block will not create problems in the unexpected time. 

 

There is a g4l package (Ghost for Linux) Ghost for Linux is a hard disk and partition imaging and cloning tool similar to "Norton Ghost"(c) and ™ by Symantec. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click’n'Clone" function. g4l supports file splitting if the local filesystem does not support writing files >2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.  The problem with G4L is that it used bit-to-bit copy, so I can not release big disk images to small disks. 

And, here is a very good tutorial on GRUB and LILO from IBM:
