At incident.io, we're acutely aware that we handle incredibly sensitive data on behalf of our customers. Moving fast and breaking things is all well and good, but keeping our customer data safe isn't something we can compromise on. We run incident.io as a multi-tenant application, which means we have a single database (and a single application).

We recently announced the release of our RemoteWrite SDK to support custom metrics from applications using several different languages – The first SDKs allow shipping of metrics from Golang (Go), Python, Java, Node.js, and.NET. This tutorial will cover the Golang SDK. The SDKs cover not just Logz.io, but can be used by any platform that supports the Prometheus remote write endpoint.

Use this guide to write a golang application emitting traces using the OpenTelemetry Protocol (OTLP) Specification. All you need is a basic understanding of developing applications in golang.

Every developer knows there are some utilities that are completely indispensable from their workflows. The programmer’s toolbelt, if you will. These toolbelts are usually different from person to person, but if there is one tool that everyone should use or at least know how to use, it is tcpdump. If you are unfamiliar, tcpdump is a tool that allows you to dump and inspect live network traffic being observed on a network interface.

Serverless applications streamline development by allowing you to focus on writing and deploying code rather than managing and provisioning infrastructure. To help you monitor the performance of your serverless applications, last year we released distributed tracing for AWS Lambda to provide comprehensive visibility across your serverless applications.

I’ve recently started working on a new project to build a Discord bot in Go, mostly as a way to learn more Go but also so I can use it to manage various things in Azure and potentially elsewhere. I figured it’d be useful to document some of this project to give some insights as to what I’ve done and why. Next up is the bot itself and how I integrated it into Honeycomb to get some visibility on how different commands are running.

I figured it’d be useful to document some of this project to give some insights as to what I’ve done and why. First up was setting up the CI/CD pipeline for it so that I don’t need to worry about it later and can save myself a bunch of time when testing.

How many major versions of a given Go module are there? That simple question doesn’t always have an easy-to-discover answer. Golang’s unique system of semantic import versioning solves some key problems of ensuring Go module compatibility across dependencies. But it also makes it a bit harder to learn what major versions of a Go module are available. The go client doesn’t provide a way to find out, nor will it inform you when a newer major version of a dependency exists.

This blog post is a part of Mattermost’s public disclosure of three serious vulnerabilities in Go’s encoding/xml related to tokenization round-trips. The public disclosure comes as a result of several months of work, including collaborating with the Go security team since August 2020 and with affected downstream project maintainers since earlier this month.
