Ruby

When it comes to validation, I don’t like to re-invent the wheel. Many programming languages have built-in modules for common types of data, such as a URL.

In Ruby, we have the URI module which is often used to generate, parse, and manipulate a URI. It has a method URI.parse which accepts a string and creates an instance of a URI.

For a time, I thought this was a decent approach to use. You could validate a string as a URL doing something like:

Include the current application environment in your prompts.

Give yourself an alert about the current Kubernetes namespace when launching a Bash shell or Rails console.

Running Python, Ruby, and Perl from one Bash script to detect the CD-ROM drive tray status using Linux ioctl.

When running a brew upgrade, it upgraded readline to version 7.0. This broke the Rails console.

Faced with having to script out schema and objects from a SQL Server database, the only option was using SMO. That’s a Windows-only solution that has some known bugs and performance problems. Using the management views in SQL Server you can script everything out yourself. So I created mossy to do that in Ruby. It can script out a whole database in under 15 queries and depending on the size of modules, should only takes a few seconds.
