GPIOs and Go
Go Advent, Dec. 22, 2018 Recently, I decided that I needed a small heads up display for import things I kept forgetting, like the time until an event started or number of unread emails in my inbox.
Members, Methods, and Interfaces
Opaque Datatypes Considered Awesome I am periodically reminded that many people don’t realize that C actually allows the creation of opaque data types. This is a possibly-surprising side effect of the option of never completing a type.
Introducing Glot the plotting library for Golang
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. It provides an expressive syntax with its lightweight type system and comes with concurrency as a built-in feature at the language level.
LLVM IR and Go
In this post, we’ll look at how to build Go programs – such as compilers and static analysis tools – that interact with the LLVM compiler framework using the LLVM IR assembly language.
Goroutine Leaks - The Abandoned Receivers
Introduction Goroutine Leaks are a common cause of memory leaks in Go programs. In my previous post, I presented an introduction to Goroutine leaks and provided one example of a common mistake that many Go developers make. Continuing that work, this post presents another scenario...
Watermill v0.2.0 released
Let me start by thanking all contributors for feedback on Watermill - it drives us to add new features. Thanks! It’s been almost a month since the initial release of Watermill. However, it’s just the beginning and we are still working hard to ship new features. What i...
Go and Apache Arrow: building blocks for data science
Today we will see how Apache Arrow could be useful for data science, or – really – a lot of analysis workloads. Lingua franca In Data Science and in many scientific fields, the lingua franca is Python.
Apache Beam and Google Dataflow in Go
Overview Apache Beam (batch and stream) is a powerful tool for handling embarrassingly parallel workloads. It is a evolution of Google’s Flume, which provides batch and streaming data processing based on the MapReduce concepts.
Golang: cache things using interfaces
Caching things can be hard to do and hard to test. In this post I’ll demonstrate a convenient way of doing that using interfaces. The problem Let’s suppose we want to cache calls to the GitHub API. Let’s say we want to get the my repository list for whatever re...
The Relationship Between Interfaces and Reflection
Interfaces are one of the fundamental tools for abstraction in Go. Interfaces store type information when assigned a value. Reflection is a method of examining type and value information at runtime.
