url shortening was a fucking awful idea
|Archiving status||In progress...|
|IRC channel||(on hackint)|
TinyURL, bit.ly and other similar services allow long URLs to be converted to smaller ones on their specific service; the small URL is visited by a consumer and their web browser is redirected to the long URL.
Such services are a ticking timebomb. If they go away, get hacked or sell out millions of links will be lost (see Wikipedia: Link Rot). Archive.org/301Works is acting as an escrow for URL shortener databases, but they rely on URL shorteners to actually give them their databases. Even 301Works founding member bit.ly does not actually share their databases and most other big shorteners don't share theirs either.
Who did this?
- User:Scumola started this wiki page
- User:Chronomex started the Urlteam scraping effort
- User:Soult Helps with scraping
- User:Jeroenz0r Helps with scraping (and stalking Soult)
- ... many ArchiveTeam people who run the scrapers
The fine folks at archive.org have provides us with upload permissions to the 301Works archive: http://www.archive.org/details/301utm. They unfortunately do not want to make them downloadable, but the same data is in our torrents too, just in a different format (we use tab-delimited, xz-compressed files while 301works uses comma-delimited uncompressed files).
- fetcher.pl: Perl-based scraper by User:Chronomex
- TinyBack: Python 2.x-based, distributed scraper (also works with the Warrior)
The easiest way to help with scraping is to run the Warrior and select the URLTeam project. You can also run TinyBack outside the warrior, thought Python 2.6 or newer is required:
git clone https://github.com/soult/tinyback cd tinyback # Use ./run.py --help for more information on command-line options ./run.py --tracker=http://tracker.tinyarchive.org/v1/ --num-threads=3 --sleep=180
The new table includes shorteners we have already started to scrape.
