Part of implementing an error monitoring platform like elmah.io is dealing with the IP addresses of the clients generating errors. In this post, I'll show you parts of how we have implemented this in ASP.NET Core, to make sure that different hosting scenarios still produce the ...

Someone asked me about the possibility of turning on a light on new errors logged to elmah.io the other day. While we offer dashboards to put on a big screen in the office, I hadn't thought much about turning physical things on and off on errors. This ...

But after having migrated everything to serverless Azure Functions, ...

Chrome revolutionized the way to extend browsers with new features. Back in the day, extensions were annoying toolbars (remember the Ask toolbar?) and related spam-like additions. Today, I couldn't live without extensions. Here's a list of our favorite extensions used while developing elmah.io. Let' ...
