Ruby and Rails Naming Conventions | IT.Signals
I’ve been looking for a consolidated list of all Ruby and Rails naming conventions without too much luck so I’ve started my own. I find I always forget the naming convention especially as I move between projects that use different languages. Lowercase letter followed by other characters, naming convention states that it is better to use underscores rather than camelBack for multiple word names, e.g. mileage, variable_xyz Instance Variables
Working with time zones in Ruby on Rails — Elabs
Rails provides great tools for working with time zones but there’s still a lot of things that can go wrong.
Débuter avec Ruby - Les bases de Ruby | CreatiQ
Débuter avec Ruby Dans ce tutoriel nous allons aborder l'installation de Ruby, nous allons par la suite commencer a découvrir la syntaxe du langage, en parlant des variables, types de données et les fonctions Lorsque j'ai installé Rail + package, je suis le tutot tout fonctionne mais lorsqu'il s'agit d'utiliser l'éditeur, j'écris l'encodage sur Notepad, et quand je sauvegarde il n'est pas indexé comme fichier ruby, donc quand j'ouvre l'invité de commande en C:/ sites, il ne trouve pas le fichier et me mais un "no such file or directory"
Practicing Ruby - USP: Prerequisite Knowledge
I would like to do a series of mailing list posts on the subject of Unix systems programming in Ruby. I only intend to cover standardized, POSIX -compliant features of the standard Ruby distribution.IO#close – fclose(3), close(2) Copies Ruby buffers to the kernel, invalidates the IO object and releases the file descriptor so it may be reused by the kernel.
Practicing Ruby - USP: basic IO methods
Directories are containers for files, and directories are also files. Similarly, Ruby Hashes are containers for Objects, and Hashes are also Objects.
Practicing Ruby - USP: Directories on the filesystem
Practicing Ruby - USP: Unix time and the Ruby Time class
The Unix epoch is defined as January 1, 1970, 00:00:00 UTC (Coordinated Universal Time).
Practicing Ruby - USP: An introduction to the Unix pipe
The Unix pipe is the first example of an anonymous file we will cover. Unlike regular files and directories, anonymous files do not exist on the filesystem and do not persist across reboots. Only the process that creates the anonymous file (and its descendants) can access anonymous files.
The IO class wraps file descriptors as Ruby objects and provides instance methods which wrap system calls. Each IO object wraps one OS file descriptor. IO also provides userspace buffering to avoid system calls and utility methods to make a programmer’s life easier.
Practicing Ruby - USP: The Ruby IO Class
Note: The original plan was also to discuss poll and epoll/kqueue solutions in this post as well.
