Golang News, Tutorials, Go Libraries and Golang Jobs
Golang 1.18 has been out for a while now. Are you using Generics? At first, the author was delighted and started gradually switching from map and filter-like statements to github.com/samber/lo, and he created an internal slice package to add some more variants. However, somewhere in his heart, he felt frustration building up. I felt like I was […]
One of the possible issues of implementing concurrent programs in Golang is data race conditions. This article discusses this topic in detail and techniques used for identifying where race conditions can occur, strategies to prevent them and how Golang handles data shared between different concurrent contexts. Before we start, if you are new to concurrency […]
In this golang article, we are going to learn how to make a simple Golang gRPC server and the Python stub (gRPC client) to use that service. As a bonus, we will learn how to work with the partial update using Fieldmask. Overview: Python-based gRPC client makes the corresponding RPC call for its requirement. Golang-based gRPC […]
Back in 2011, Rob Pike gave a talk on the topic of Lexical Scanning in Golang, where he presented an interesting approach to lexical analysis with coroutines (implemented via goroutines communicating over a channel). Since the author has been pondering the connection between coroutines and state machines in the past, Rob’s talk inspired the author to try approximating […]
In this tutorial, you will learn how to build a web scraper with Golang and Colly. Sometimes some things just don’t have an API. In those kinds of cases, you can always just write a little web scraper to help you get the data you need. The author going to be working with Golang and […]
This article demonstrates the use of Goroutines & WaitGroups for writing concurrent programs in GoLang. In GoLang, when we use the go keyword means starting a new goroutine to perform a specific job in the background. Think of a goroutine as a thread to understand this article – although goroutines are not threads. Meanwhile, the caller function will go ahead & can continue to execute its […]
