Hello my fellow Bitcoin hackers...
I have made this service, like a TinyURL but not because I don't have a short domain.
The killer feature is the thumbnail generation. It's fast, free and has no watermark.
This uses a psuedo-hash involving base 62 encoding and prime numbers near the golden ratio.
Each website is stored with a unique integer value, so the "hash" will always be unique and there will never be a collision-- but furthermore, the same URL always has the same hash.
Also, I implemented an auto-complete using a very large dataset of Alexa's top sites.
I am not much of a developer, so I just made this for fun and to brush up on my PHP skills.
This is intended to be Bitcoin-friendly. . . if I can get a short domain I would be happy to deploy it there.
Feel free to use and share it!
