Using Go for Anomaly Detection

Contributed by

As engineers, we need to know how our applications and services are performing in realtime and isolate any problems as quickly as possible. While there is a plethora of tools to collect, store and graph metrics from infrastructure, there are fewer tools for performing analysis on these metrics. Anomaly detection, currently a hot topic in web operations circles, is concerned with automated detection of anomalous circumstances which could indicate a problem.

Go at Sourcegraph - Serving Terabytes of Git Data, Tracing App Performance, and Caching HTTP Resources

Contributed by

Sourcegraph is a code search and review application that supports and analyzes code in multiple languages: Go, Python, Java, Ruby, JavaScript, and soon more. Even though we have experts in each language on our team, Sourcegraph’s core has been written in Go since day one, and we’ve chosen Go for each new project and system we’ve built. We’ll run through all of the major open-source systems and projects we’ve built within Sourcegraph in Go.

Go at Datadog

Contributed by

Go at Datadog In the last year, Go has started to supplant parts of our intake pipeline at Datadog that were previously written in Python. The embrace of Go by users of dynamic languages is well documented, generally focusing on the performance and memory usage benefits of switching to a compiled language that lacks heavy per-object overhead. We could tell the same story. Datadog is a SaaS cloud monitoring and metrics platform, and because of an increasing focus on horizontal scaling in the cloud, our users have lots of servers, and their servers send us lots of data.

Advanced Reflection with Go at HashiCorp

Contributed by

Advanced Reflection with Go at HashiCorp HashiCorp builds a diverse set of popular DevOps tools written in Go: Packer, Serf, Consul, and Terraform. While these tools range from desktop software to highly scalable distributed systems, their internals all have one thing in common: they use reflection, and a lot of it. In this post, I’ll share the libraries and techniques we use at HashiCorp to get the most out of reflection, all while being safe and efficient.

Go at CoreOS

Contributed by

Go at CoreOS When we launched the CoreOS project we knew from the very beginning that everything we built would be written in Go. This was not to make a fashion statement, but rather Go happened to be the perfect platform for reaching our goals – to build products that make distributed computing as easy as installing a Linux distro. It’s been almost 10 years since a new Linux distro hit the scene, and during that time Python was the language of choice.

How Go Helped Shape Splice's engineering culture

Contributed by

Go is a trendy programming language, but let’s be honest: the Go language doesn’t have anything new that wasn’t first implemented somewhere else. As a matter of fact, Go is a pretty boring programming language. Why would anyone pay attention to a typed compiled language that doesn’t have generics, doesn’t let you do metaprogramming, doesn’t support inheritance and, as some said, feels like we are taken back to the 70s?

Kite: Library for writing distributed microservices

Contributed by

Writing web services with Go is super easy. The simple but powerful net/http package lets you write performant web services in a very quick way. However sometimes all you want is to write a RPC backend application. Basically you want to have many independent worker applications that are running separately, each with their own responsibility of doing certain tasks. They should accept requests and reply to them with a well defined response.

OpenShift 3 and Go: Teaching Old Dogs New Tricks

Contributed by

The first commit to OpenShift (the Platform as a Service that is so hipster that we were doing containers even before it was cool) was four years ago. From day one it’s been about making a platform that helps developers and operations move their applications into a cloudy future with the tools and technologies that they are already familiar with. As developers, we love working on brand new things: things written in the newest languages, the hottest stacks, and the trendiest databases.

Inspeqtor

Contributed by

When I decided to build Inspeqtor (source), I had a fundamental choice: what language should I build it in? I’ve worked in Ruby for the last 8 years so it was a natural choice: “use the tool you know best” is never a bad choice when solving your own problem. However I’m not building something for myself: I’m building a product that will be used by thousands of others. Since Inspeqtor is an infrastructure monitoring tool, it needs to run 24⁄7 efficiently and reliably.

Gogs: GitLab alternative in Go

Contributed by

What is Gogs and why we make it? Gogs is a painless self-hosted Git Service written in Go. It aims to make the easiest, fastest and most painless way to set up a self-hosted Git service. With Go, this can be done in independent binary distribution across ALL platforms that Go supports, including Linux, Mac OS X, and Windows. Why we choose Go? As a strong type and compiled system programming language, Go has significant ability to catch errors at compile time to reduce possibility of runtime errors, and it is extremely useful when we want to make changes in the project.
