Community Picks·4yHow To Use Multithreading in Node.js
Since JavaScript is single-threaded, it blocks the main thread and no other code executes until the task completes. To understand this, you will create a Node.js program with an infinite loop so that it doesn’t exit when run. Using nano or your preferred text editor, create and open the process.js file: nano process.
Community Picks·4yHow to be Better at Algorithms? | Examples for Beginners
The design of an algorithm depends on the complexity of the problem it needs to solve. Pointer Traversal or Pathfinding: when searching a graph or network, it’s important to use a proven search algorithm. Hash Table: Hash table algorithms are used for a variety of purposes, such as collision detection and pathfinding.
Towards Dev·4yuseMemo and useCallback in React
memoization or memoisation is an optimization technique used to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same inputs occur again. In React, memoization has the same philosophy but it’s a little bit different but it's a bit different to memoization.
Coins Bench·4yIntroduction to Blockchain
Bitcoin is decentralized and trustless, meaning there is no trusted authority which controls updates. If any node could make updates to the database at any time, there would be conflicts, fake transactions, inconsistencies between different nodes’s copies of the database.
Community Picks·3yDoes Async-Await and Promises Guarantee Asynchronous Code? No (and Here’s Why)
Async-Await and Promises Guarantee Asynchronous Code? No (and Here’s Why) This article busts this myth with a few examples and tells you when your code is truly asynchronous and non-blocking. JavaScript is single-threaded.
gitconnected·4y7 Best Tools for Monitoring Node.js Servers.
There are several tools available for monitoring servers, but few are designed specifically for Node.js. In this post, we will discover the 7 best of them. PM2 PM2 is a potent instrument to run Node applications, but it is also very good at maintaining and monitoring standalone applications in production servers.
ByteByteGo·4yMessage Queue and NoSQL with 10x Performance Boost
When Apache Cassandra came out around the late 2000s, AWS EC2 instances with a few physical cores and 64GB of RAM were considered high end. In order to take full advantage of these advances, high performance software requires new designs.
Honeybadger·4yMultithreading in JavaScript with Web Workers
Single-threaded JavaScript VM is fundamentally designed to spawn a single thread, which means that it cannot read and execute multiple instructions simultaneously. When we see a function execution hindering the following function from executing for a few seconds, wait because a singlethread is handling a blocking process.
InfoWorld·4yIf Heroku is so special, why is it dying?
A golden age of developer experience Heroku is back in the news because it recently announced the elimination of its free tier. Why is Kubernetes and not Heroku the increasingly default way to build and scale applications? Some suggest Heroku was simply ahead of its time.

FastAPI Production hints FastAPI is a modern, fast (high-performance) web framework for building APIs with Python. In the last 3 years, it has been very popular among back-end developers that are using Python. It is asynchronous and fast because of mainly uses Startlette.
ByteByteGo·4yEP31: Super High-performance NoSQL and MQ
The data platform ingests, processes, analyzes and presents data generated by different data sources. No JVM, No GC Kafka and Cassandra are written in JVM-compatible languages and usually suffer from high tail latency. Redpanda and ScyllaDB are rewritten from scratch using C++ and leverages some new frameworks.
Go·4yGo runtime: 4 years later
The Go GC returns unneeded memory back to the operating system much more proactively, reducing excess memory consumption and the chance of out-of-memory errors. Pool, a GC-aware tool for reusing memory, has a lower latency impact and recycles memory much more effectively than before.
AWS Tip·4yDeploy an API tool in 10 minutes
The core idea of Serverless is to make the server as a computing resource no longer need the attention of users. FaaS (Functions as a Service) functions as a service. Later, we will use the serverless API to implement a service that uses Node to help clients send API requests and get responses.
Medium·4yFive Reasons Why You Should Learn Rust
Rust's ownership model is genuinely a new and refreshing concept for me, says Idan Zalzberg. Rust guarantees memory safety without garbage collectors or automatic reference counting. Rust expands that idea into thread safety. It's a new mental model and can take some time to learn.

It is becoming evident that the NPUs will feature in many computing devices going forward.
Hacker News·4y6 Docker Compose Best Practices for Dev and Prod
Docker Compose is a tool for defining and running multi-container Docker applications. It allows you to bring up and link multiple containers into one logical unit. If you want to use Docker containers, you create one container that listens on an unused port on your machine. The alias will give it precedence when two services could share a Dockerfile and a code base but have some slight variations.
