Nearly eight years ago, Cory and I started on a journey to help developers build software quickly and painlessly. As software developers ourselves, we had felt the pain of being afraid to ship and spending late nights tracking down bugs. In 2013, we launched Rollbar into the world so that developers could build software faster, shipping often without fear. These days, lots of people talk about continuous delivery, and nearly all of them focus on automating releases.

In today’s post, we’ll learn how to build a Rails app that can support multiple subdomains. Let’s assume that we have a gaming website funkygames.co and we want to support multiple subdomains such as app.funkygames.co, api.funkygames.co, and dev.funkygames.co with a single Rails application. We want to ensure that proper authentication is performed for all subdomains and that there are no duplicate routes.

If you're using a Linux server, you're probably familiar with the term load average/system load. Measuring the load average is critical to understanding how your servers are performing; if overloaded, you need to kill or optimize the processes consuming high amounts of resources, or provide more resources to balance the workload. But how do you determine if your server has sufficient load capacity, and when should you be worried? Let's dive in and find out.

With Internet Explorer on the brink of death and its Edge browser close to it with a 4% share of the user base, Microsoft has finally completed the shift of the software’s rendering engine to Blink, the foundation for Google Chrome. This makes Edge one of the latest in a growing family of Chromium based web browsers. But what does this mean for Windows users — and what special features of the new Edge are worth knowing about? That’s what we’ll be exploring in this article.

You’ve likely heard a thing—or two (ba dum tss!)—about two-factor authentication, or 2FA. After all, it’s become a bit of a hot topic recently as the nature and number of security breaches has evolved. Compromised user data regularly surfaces on the dark web, giving malicious actors access to your password(s) for a couple bucks. That’s why passwords just don’t cut it as your only security effort anymore—and that’s where 2FA comes in.

We're happy to announce that we've just launched our newly designed dashboard for our logs & metrics platform, allowing DevOps & security professionals to see their vital metrics quicker than ever before. Our team has been keen to respond to the needs of our users through undertaking dedicated research which informed the creation of this latest update to the platform's design. This new design provides improved real-time feedback to users managing & creating new ELK stacks.

Analyst firm Gartner has predicted that 75% of organizations will have deployed a multi-cloud or hybrid cloud model by 2020. While enterprises are using different cloud providers to meet business and technology needs, multi-cloud deployments bring an additional layer of management complexity for IT operations teams.

Next in our series on the Amazon Builders’ Library, Lumigo Director of Engineering – and newly-minted Serverless Hero – Efi Merdler-Kravitz picks out the key insights from the article, Instrumenting distributed systems for operational visibility, by AWS Principal Engineer (AWS Lambda), David Yanacek.

The team at Let's Encrypt, the free certificate authority, has identified an issue that might have lead to unauthorized certificate issuance. Because it's hard to determine which sites have been abused, they have no other choice but to revoke all certificates that may have been maliciously issued. The result is a massive 3,048,289 certificates that will be revoked within the next 24 hours. We've just finished alerting all our users that are affected by this.
