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.
one can do just as well by selecting a set of scores that have some validity for predicting the outcome and adjusting the values to make them comparable ( by using standard scores or ranks). introduction to sorting algorithms. if you don' t have this gem on your system, install it by running gem install humanize. now let' s dive into the code: copy.
analyzing algorithms bysizeof a problem, we will mean the size of its input ( measured in bits). cost as function of input size. 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. our model for computation cost: random access machineuntil.
