Community Picks·4yfRPC: A Faster, More Flexible RPC Framework
fRPC is an RPC framework that's designed from the ground up to be lightweight, extensible, and extremely performant. It uses a completely custom messaging format and generates a highly-optimized client/server implementation. It's available now in early alpha under the Apache 2 open source license. The benchmarks were performed over a local network to avoid inconsistencies due to network latency.
Quick Code·4y5 Free Golang Courses to learn Go Programming
Golang is an open-source programming language developed at Google by Rob Pike, Robert Griesemer, and Ken Thompson. It is a procedural, compile-time, and statically-typed programming language designed by Google to address the problems that Google had in developing software at scale. In this Golang course, we will cover: Loops Arrays Maps Structs and Structs.
Dev Genius·4yConcurrency in Go is hard
Go is generally known for having good built-in support for concurrency in Go. The solution was fixed in #2171 by using sync. It could also have been fixed without using the sync package by using an init function to set the variable v once. When the doSomething function is evaluated, running RLock / RUnlock will not affect the original lock in the User struct rendering it useless. The solution uses a pointer.
LogRocket·4yBuilding a full-stack app with Bud and Go
New Go framework Bud allows frontend and backend code to expand based on the needs of its users. Bud is a framework that keeps things simple but can scale up when needed. Bud comes with built-in functionality for frontend development with Svelte and uses Go for the backend. The index method would return a view from a file called index.svelte in our view folder.
gitconnected·4yHow to build a (simple) blog using Rust
Rust is an amazing language both in terms of speed of the execution and developer experience. The goal of the rewrite is to get something out which could serve as a learning example and be built upon to further my understanding of the language. For this project, serde will be used for serializing the metadata of a blog post. This is macro, or more precisely, a proc_macro.
Hacker Noon·4yWhy You Need to Learn Multiple Programming Languages
Boot.dev is a battery-included computer science curriculum in the browser. The full curriculum will only require the use of about 6 languages in total. The majority of the program can just use JavaScript, Python, and Go. If you only write one programming language, it’s easy to assume a certain You might find yourself needing to look up syntax occasionally, but everyone does that.
Hashnode·4yTransitioning Into Web3 As a Frontend, Backend, or Fullstack Developer
A full-stack developer has the knowledge and abilities to work on a web application's front and backend. This includes HTML, CSS, Javascript, Reactjs, or Angular on the frontend (client) and coding with Javascript, Java, Go lang or C# on the backend (server side)
Quastor Daily·4yHow Netflix Implements Load Shedding
API Gateway sits between the backend and the client and it handles things like rate limiting, authentication, monitoring and routing requests. The first decision was where to implement the load shedding algorithm. Zuul will throttle requests below a certain priority threshold. This is meant to protect the API gateway itself. The metrics used to trigger global throttling are concurrent.
Golang News·4yHow to implement gRPC with Golang
How to implement gRPC with Golang will show you how to build a basic unary server-client. The unary could be the simplest because it just involves a request and a response. The client makes the request by sending the needed information by calling the related method to execute the action.
Big Nerd Ranch·4yGo Generics in API Design
Go Generics in API Design Go 1.18 has finally landed, and with it comes its own flavor of generics. For example, you should try to handle errors before using panic since the latter will end up exiting your program. Since this compiles, we won’t know this broke something until we deploy and get the bug report.
InfoWorld·4yWhat’s the Go programming language (Golang) really good for?
Google's Go language, aka Golang, has evolved from being a curiosity for alpha geeks to being the battle-tested programming language behind some of the world’s most important cloud-centric projects. Go is designed to err on the side of being small and easy to understand, with certain features deliberately omitted.
Hacker News·4yDon’t call it a comeback: Why Java is still champ
Java has been among the top three languages since its launch in 1995. Companies like Amazon, Google, Netflix, Pinterest, Spotify, Square, and Zoom all employ Java across their codebases. In just two years Java ranked number three in popularity, outpaced only by C and C++.
Medium·4yAtomic Pointers in Go 1.19
Objective-C has atomic properties, it ensures safe read and writes to a property from different threads. Since Go is multithreaded, it supports atomic operations as well. Pointer is a great way to bring atomic memory primitives into your program. It is a simple way to prevent data races without fancy mutex code in place. The code with atomic pointers returned no feedback regarding a data race.
Hacker News·4yI replaced all our blog thumbnails using DALL·E 2 for $45: here’s what I learned
AI generated images from DALL-E make better blog thumbnails, do it cheaper, and generally just be more fun? I spent the weekend and $45 in OpenAi credits generating new thumbnails that better represent the content of all 100+ posts from It’s worth some time browsing r/dalle2 to get some ideas for what goes into a good prompt.
Golang News·4yA Golang low-code engine to create web services and dashboards

Golang News·4ySubstrings vs. Regular Expressions – Benchmarking in Golang
In this third part of a four-part series, we’ll cover benchmarking in Go using our text filtering tool as a test subject. Using these tools, we can garner insights on whether the tool runs faster (under these scenarios) using substring or pattern matching.
ITNEXT·4yMy Contribution to a Popular Open-Source Package Caused a Panic in Golang Projects
My Contribution to a Popular Open-Source Package Caused a Panic in Golang Projects Hello. I will tell you how my development to a popular open-source project caused errors to people using the project around the world. The swaggo/swag project is one of the most popular and widely used solutions. But in reality it may not be so.
Semaphore·4yA Developer’s Guide to Terraform
Terraform is a platform-agnostic tool that defines infrastructure in human-readable code. Terraform code describes the end state of the infrastructure after creation or change, not the instructions for making the change. The provider turns the declarative code into imperative instructions.
LogRocket·4yA guide to JWT authentication in Go
Go 1.16 or later installed on your machine (for security reasons) Experience building web applications in Go or any other language (optional) The golang-jWT package is the most popular package for implementing JWTs in Go, owing to its features and ease of use. You will need a secret key to generate JWT tokens using the Golang-JWT package. If you want to modify the JWT, you can use the claims method. If there are no errors, you should use the Claims method.
