    Hashids

    Hashids

    A small PHP library to generate YouTube-like IDs from numbers

    Hashids is a small open-source library that generates short, unique, non-sequential ids from numbers. It converts numbers like 347 into strings like “yr8”, or array of numbers like [27, 986] into “3kTMd”. You can also decode those ids back. This is useful in bundling several parameters into one or simply using them as short UIDs. Hashids works similarly to the way integers are converted to hex, but with a few exceptions. The alphabet is not base16, but base base62 by default. The alphabet is...

    ThinORM

    A lightweight ORM that does not require annotations.

    This project was the result of working on systems constrained to versions of Java < 1.5 and including a great deal of code dealing with object persistence. This project was essentially a proof-of-concept to determine whether or not I could create, essentially, an alternative to JPA that did not rely on annotations. I was able to create a working system, and a fairly lightweight one at that, but it would require a great deal of work to be production ready.
