Did you know that Ruby provides a way for your script to use its own source file as a source of data? It's a neat trick that can save you some time when writing one-off scripts and proofs of concept. Let's check it out!
Have you ever had a bunch of data in an array, but needed to do a key/value lookup like you would with a hash? Fortunately, Ruby provides a mechanism for treating arrays as key-value structures. Let's check it out!
Files are just large collections of lines or characters. Lazy enumerators make it possible to to some very interesting and powerful things with them.
Just how much slower are exceptions than other flow control mechanisms? In this post we use a simple benchmark to find out.
Ruby 2.1 and later support nested exceptions via the Exception#cause method. Now you can view these for any error reported to Honeybadger. This post gives a brief introduction to exception causes in Ruby, and shows you what they look like in the Honeybadger UI.
It's a common misconception that the raise method only accepts exceptions as its argument. This post will show you how you can raise ANYTHING, including numbers, dates, and your own custom classes.
One of the nice things about working with rails is that when something goes wrong in development, you get a really nice error detail page. Today we're going to take a look at how these fancy error pages work.
It’s easy to find code snippets that will delete the jobs from one Sidekiq queue. But we have lots of queues. I want to clear the jobs from all of them. After a little digging, I came up with an answer that seems to work well.
Fiddle is a little-known module that was added to Ruby's standard library in 1.9.x. It allow you to interact directly with C libraries from Ruby. In this post we'll start with some simple examples and finish by using termios to talk to an arduino over a serial port.
Sometimes the standard backtrace / error message combo isn't enough. Sometimes you need extra data to locate the cause of an error. In this post we'll discuss three easy ways to add more context to your exceptions.
