note: jruby versions of the bcrypt gem < = 2. 3 had a security vulnerability that was fixed in > = 2. if you used a vulnerable version to hash passwords with international characters in them, you will need to re- hash those passwords.
this vulnerability only affected the jruby gem. how to install bcrypt gem install bcrypt. after searching resources for learning algorithms and data- structures in ruby when i didn' t find any good resource.
so, i took this initiative to build a platform for learning and discussing algorithms and data- structures in ruby. this blog aims to be a platform where anyone can learn algorithms and data- structures in ruby. before there were computers, there were algorithms. but now that there are com- puters, there are even more algorithms, and algorithms lie at the heart of computing.
this book provides a comprehensive introduction to the modern study of com- puter algorithms. it presents many algorithms and covers them in considerable. dawes observed that the complex statistical algorithm adds little or no value.

In a problem of ﬁxed size, the cost will be inﬂuenced by too many accidental factors: this makes it hard to draw lessons applicable to future cases. It' ll take a while to complete ( i' ve been at it for over 7 years), but it' s already usable. By ilya grigorik on ap. Introduction to algorithms lecture notes.
