In this post we'll use a little-known command line flag to spy on Ruby as it parses our code.
Did you know that it's possible to log all method calls as they occur in a running process in real time? How about injecting code to be executed inside of a running process? You can – via the magic of the rbtrace gem.
In this post we'll discuss some non-obvious behavior of class variables and show how it's all the fault of lexical scoping.
Have you ever needed to group items in an array, or lines in a file? In this post we'll discuss a few often-overlooked Enumerable methods that let you do just that.
The humble splat operator (`*`) is one of those features of Ruby that just gets more interesting the more you look at it. In this post we'll talk about how you can construct and manipulate arrays with splats.
In this post we'll follow the journey of a simple program as it's lexed, parsed and compiled into bytecode. We'll use the tools that Ruby gives us to spy on the interpreter every step of the way.
A lot of problems faced by beginning Rubyists are caused by not understanding `self`. In this post we'll take a deep dive into `self` under conditions both common and uncommon.
Ruby supports using regex in lots of interesting ways that go beyond the basic `String#match` method. In this post I cover a few of my favorites.
In this post, we'll dive into regex conditionals and discuss how to work around the limitations in Ruby's implementation of them
Are refinements slow? I wrote a few benchmarks to find out. The answer was surprising.
If you've never used Ruby's refinements, you might be surprised to learn that they're lexically scoped. We'll discuss what this means, and the implications for your code.
In this post, we'll discuss how to separate an HTML document into logical sections based on heading tags. I'll all also show you a cool trick for rendering arbitrarily-deep subnavigation trees using Liquid templates.
Longer pages often benefit from subnavigation. In this post, we'll make a Jekyll plugin to dynamically generate subnavigation from H2 tags.
When your service fails due to an exception in your application code (Ruby, Go, Elixir, etc...), Honeybadger alerts you. Unfortunately, application errors are only half the story. What happens when something goes wrong outside of your application code? You probably use something like our Uptime Monitoring to be alerted of catastrophic outages such as when EC2 is down, DNS fails, or one of the other myriad scenarios play out.
We are very proud to announce that Honeybadger now officially supports reporting exceptions and errors -- with advanced features such as nested exceptions and request data! -- from Java web applications.
Over the past few months we've been working on delivering an improved search experience for Honeybadger customers, and today we're happy to announce that it's finally ready. Our goal was to provide more advanced search options for the data you've been sending us while keeping simple searches simple, and I think we've accomplished that. We'll still support the simple "just enter some text to do a quick wildcard search", but now we'll also support more specific searches, like the following:
You tried turbolinks, once, and soon your app began to fail in strange and wonderful ways. But some people make it work. What's their secret? The answer is so simple, it just might amaze you.
When you treat your collections as enumerators, you get to use all your favorite functions like #map and #reduce without having to write any extra code. In this post I show you how easy it is to create enumerators on the fly, without defining extra classes or messing around with the Enumerable module.
These days it's pretty common to see #freeze used in Ruby code. But it's often not entirely clear WHY freeze is being used. In this post we'll look at the most common reasons a developer might freeze variables.
If you want your app to behave well in a unix environment, it's important that it exit correctly. In this post you'll learn all about unix exit codes, the mechanism that Ruby uses to exit a program, and how you can add custom behavior on exit.
