This is a guest post from Ava Franklin of GoodCore Software. No matter how high your aspirations, you need someone to guide you through the initial steps of your career. For developers who have just started taking up real projects, we have prepared a checklist of best programming practices recommended by software development industry experts.

For a comparatively better user experience and more quality online traffic, all that’s required is a fast and lightweight website. The contribution of a lightweight and superfast website, towards comparatively better user experience and engaging online traffic, cannot be ignored. One of the most important aspects that has always kept the user hooked, engaged, has converted, ensuring optimal performance and reliability of the website is - load testing.

Your network is continuously becoming more complex. Whether you’re migrating to the cloud, deploying containers, or load balancing your applications, getting visibility into your network’s architecture is increasingly difficult—yet more important than ever.

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.

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.

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.

The ability to search through individual error events (we call them Notices) has been one of our most requested features. Today we are shipping an updated section to our Errors page that allows you to do exactly that.

Certificates can be difficult to track and opaque to administrators, and if any expire without someone noticing, embarrassing outages can happen. At Grafana Labs we strive to make all things visible and observable; why should certificates be any exception? In this post we will explore an easy way to expose and monitor certificate expirations using Grafana and Prometheus.

Yesterday, we sent out notifications to all our clients that are affected by the Let's Encrypt mass revocation of SSL certificates. In this post, we'll share the details how we found those certificates. Now, the morning after, we're well rested and in good shape to do a proper write-up on the matter.
