We added a useful debugging tool called Breadcrumbs. Check them out, and perhaps you will never need a random debug log in production ever again.
Alongside introducing new security features like Two-Factor Authentication (2FA) and integration with haveibeenpwned.com, we also take a quick look into the inner workings of Two-Factor Authentication.
A chance conversation let me to the realization that the world of unique identifiers is larger and more wondrous than I ever could have imagined. In this post we discuss five types of UUIDs and their upstart cousin, the ULID. We explore what makes each of them special and when they may be particularly useful.
Because Ruby is an object-oriented language, we tend to model the world as a set of objects. We say that two integers (x and y) are a Point, and a Line has two of them. While this approach is often useful, it has one big problem...
If you love Ruby and Lambda like we do, then re:Invent 2018 was like Christmas arriving early. Here's how you can get up to speed quickly with running Ruby code on Lambda.
Last week we released version 4.0.0 of the `honeybadger` Ruby gem. This release includes a long-awaited feature which makes it even easier to customize your error reports before they are sent to Honeybadger. We also did some much-needed refactoring, and made a few removals and deprecations for good measure. Don't worry, though—most of the API remains unchanged, so upgrading should be a relatively painless process for most users.
In this story, Jason Swett of The Ruby Testing Podcast discusses the pitfalls of external dependencies in your test suites, and how to avoid them.
Ad-hoc nil usage causes a lot of problems in Ruby. In this post we explore a more explicit way to handle nil conditions, inspired by Rust.
We recently shipped version 3.2 of the honeybadger Ruby Gem, which includes a new feature to make it easier to add context to your error reports.
When your autoscaling group terminates instances running Sidekiq, you should finish the Sidekiq jobs before the instance gets terminated. This is how we do that at Honeybadger.
When we have to work with text, we often reach for regular expressions. But they're not the easiest solution to every problem. Recently I was struggling with a large regexp, when I realized it'd be less work to write a parser. This article explains the process.
This article covers one of my favorite techniques for improving performance: memoization. It's a source of easy little performance wins that eventually add up and only occasionally reduce your application to a heap of smoldering rubble. Only very occasionally.
If you want Ruby's string methods to play nicely with Unicode, it's a good idea to normalize them. This article is a brief introduction to Unicode normalization for Rubyists.
The latest version of the honeybadger Ruby gem includes a lot of improvements and new features. Check it out!
One often-overlooked feature of Ruby's hashes is that you can use any object as a hash key, not just strings and symbols. In this post we examine how Optcarrot, the Ruby NES emulator, uses this feature to optimize its mapped memory implementation.
To see how far Ruby's Unicode support has come, I tested every string method to see which ones violate the principle of least surprise. The results are presented as a handy table that you can reference to see which string manipulation methods are Unicode-unfriendly.
Here's an easy way to run multiple Sidekiq processes via systemd.
In this post we'll discuss a few easy wins - things you can do when a Rails project is young to make it much easier to scale its data layer as the project grows.
You probably know how to ask Ruby to rescue specific exceptions. But how does Ruby know if a particular exception meets your criteria? In this article, we'll walk through Ruby's simple exception matching mechanism and see how we can use it to our advantage.
Many of the most common ActiveRecord idioms produce SQL which doesn't scale well as your dataset gets larger. In this article I discuss three of the worst offenders and offer work-arounds.
