  golangci-lint to enable comment check for exported functions

golangci-lint is a command line tool which aggregates a list of different go linters to check whether the source code is in correct condition from different aspects. It is built to run during the CI pipeline so that there is no obvious coding issues before compiling and building the program. It is easy to run it with just below command $ golangci-lint run -v INFO [config_reader] Config search paths: [./ /Users /] INFO [config_reader] Used config file .golangci.yml INFO [lintersdb] Active 10 li...

  Popular Golang JSON libraries evaluation

JSON (Javascript Object Notation), a prevailing data exchange format, is widely used in various platforms and languages. Golang, of course, will never miss the support for JSON. And with its own standard library, such as those interfaces like the REST API from the API Service in Kubernetes, it can easily process JSON. Although Go’s library works great, we can still seek those open-source JSON libs in Github to maximize our efficiency. Then the features, performance, applicability of these ...

  Our Go Cache Library Choices

In Build a Go KV Cache from Scratch in 20 minutes, I walked you through what matters when writing a local cache, and eventually implemented one, whose performance was beaten badly by that of the popular go-cache on Github though. However, the bright side is that we can learn a lot from those excellent Github Go cache products, studying their features, applicable scenarios, and implementations, and extracting what we need. In this article, I will mainly analyze and compare the four...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...

  Translating math into code with examples in Java, Racket, Haskell and Python

Discrete mathematical structures form the foundation of computer science.These structures are so universal that most research papers in the theory of computation, programming languages and formal methods present concepts in terms of discrete mathematics rather than code.The underlying assumption is that the reader will know how to translate these structures into a faithful implementation as a working program.A lack of material explaining this translation frustrates outsiders.What deepens that fr...

  A Sip of Go Log

Logging is indispensable in any code that we need its support both in debugging and in statistics. However, a package that filled withfmt.Println/fmt.Printf printing various messages can never be considered a read-to-be-adopted package, which can be optimized by a simple change, using Golang’s native log package to print information to standard output or to a file. Then, how to apply the log package? Are there any limitations? If so, can we seek open-source packages? Let&rsq...

  Kubernetes Authentication & Authorization 101

If we want to build a system with user modules, Authentication and Authorization are something that we can never ignore, though they could be fuzzy to understand. Authentication (from Greek: αὐθεντικÏŒς authentikos, “real, genuine”, from αὐθέντης authentes, “author”) is the act of proving an assertion, such as the identity of a computer s...

  Method chaining and lazy evaluation in Ruby

Method chaining has been all the rage lately and every database wrapper or aything else that’s uses queries seems to be doing it. But, how does it work? To figure that out, we’ll write a library that can chain method calls to build up a MongoDB query in this article. Let’s get started! Oh, and don’t worry if you haven’t used MongoDB before, I’m just using it as an example to query on. If you’re using this guide to build a querying library...

  In defence of Objective-C

An unashamed apologist’s perspective on the loveliest language i’ve worked with.I’ve worked with a lot of programming languages in my time. Not a huge number, mind you, but enough that i can say that i’m open minded and seasoned about it. And, as they say: ‘Don’t feed the trolls’ – well, i’m about to do exactly that: feed the trolls at work who love to rag on about how awful obj-c is! So here i go, foolishly treading where no sensible...

  What is goroutine?

Casual Talk Golang is quite enjoyable to write, aside from the tedious if err != nil checks. One of the fundamental reasons for the joy is goroutine, a core feature of Golang. Understanding goroutines in detail is worthwhile, as they contribute significantly to the pleasure of working with Golang. So, let's talk about goroutines, hoping to provide some insights to the readers. TL;DR: We'll start by talking about assembling a computer, then delve into some concepts of the operating system, such ...
