User experience is key to ensuring the success of your website. There are many metrics that help you gauge and improve it, but Core Web Vitals are probably the most important ones. They are a set of real-world, user-centered metrics that quantify key aspects of the user experience. By measuring dimensions of web usability such as load time, interactivity, and the stability of content as it loads, Core Web Vitals help you understand how your website is doing in terms of performance.

“If you are a managed service provider (MSP) in Switzerland, your customers are very likely Swiss customers, so they speak the local language, and they want their data to be in Switzerland, and they want your service provider to comply with all the Swiss regulations. And the same is true in 190 other countries, especially after last year,”

In December 2022, the latest version of HAProxy, 2.7.0, was released. This open-source software is both a proxy and a load balancer, and is immensely popular due to the sheer volume of features it provides to help reduce or even avoid downtime and manage web traffic. Website or application downtime is disastrous for businesses. You want to serve as many users as possible, but if you have nothing in place to manage traffic, then your web applications can quickly become overwhelmed and fail.

Flaky tests are a problem that are found in almost every codebase. By definition, a flaky test is a test that both succeeds and fails without any changes to the code. For example, a flaky test may pass when someone runs it locally, but then fails on continuous integration (CI). Another example is that a flaky test may pass on CI, but when someone pushes a commit that hasn’t touched anything related to the flaky test, the test then fails.

I’ve always been wary about vendor events. In my experience, many of them are mostly marketing pitches, with little or no content that is applicable to my use cases. Despite that, last year I decided to convince my manager to let me attend ObservabilityCON 2022 to see what I could learn from it. My hope was that I would be able to get practical knowledge that could be applied as soon as I got back to work. (Spoiler alert: I did!)

For the sake of security, performance and uptime, IT pros must find problems on the network immediately and fix them fast. Hmm. Sound like network detection and response (NDR)? It is.

Jaeger’s HotROD demo has been around for a few years. It was written with OpenTracing-based instrumentation, including a couple of OSS libraries for HTTP and gRPC middleware, and used Jaeger’s native SDK for Go, jaeger-client-go. The latter was deprecated in 2022, so we had a choice to either convert all of the HotROD app’s instrumentation to OpenTelemetry, or try the OpenTracing-bridge, which is a required part of every OpenTelemetry API / SDK.

You don’t often see real change, but when you do see it you know it. Artificial Intelligence/Machine Learning toolsets like ChatGPT are finally starting to offer broad capabilities that will benefit a mass audience. These tools are moving out of the domain of data scientists and math nerds and into mass markets with a little bit for everyone. The potential reach is awesome and a little scary.

Traffic telemetry is the data collected from network devices and used for analysis. With traffic telemetry, engineers can gain real-time visibility into traffic patterns, correlate events, and make predictions of future traffic patterns. As a critical input to a network observability platform, this data can help monitor and optimize network performance, troubleshoot issues, and detect security threats. However, traffic telemetry can be difficult to understand.
