C# 8 Interfaces: Dangerous Assumptions in Default Implementation ⚠️ One of the features that is being promoted about C# 8 interfaces is that we can add members to an interface without breaking existing implementers. ✅ But we can cause a lot of pain if we aren't careful. 🤷🏻‍♂️ Let's look at some code that makes bad assumptions so that we can understand the importance of avoiding these problems. ⛔️ [ Article ] : kutt.it/csdif 〰️〰️〰️〰️〰️〰️ #CSharp #Interfaces @ProgrammingTip

Empower Your Microservices with Istio Service Mesh 💎 Microservices popularity has grown as a lot of organizations are moving their applications to microservices which enables their teams to autonomously own and operate their own microservices. ✅ The microservices have to communicate with each other so how do you efficiently connect, secure, and monitor those services❓ Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. 📊 In this session, we will cover what is service mesh and why it is important for you, what are the core components of Istio, how to empower your microservices to leverage the features that Istio provides on top of Kubernetes such as service discovery, load balancing, resiliency, observability, and security. ⚡️ [ YouTube ] : kutt.it/istio 〰️〰️〰️〰️〰️〰️ #Microservice #Kubernetes #Istio @ProgrammingTip

Kubernetes for .NET Developers ☸️ Have you started building containerized application and struggled with scaling across multiple hosts❓ Would you like to simplify DevOps tasks such as deployment and configuration❓ Have you heard about Kubernetes and would like to learn more❓ Then this presentation is for you. 💎 Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications. 🔥 In this presentation, I will walk you through Kubernetes fundamentals, the high level architecture, how would you deploy an ASP.NET Core application to Kubernetes and finally how would you configure and launch auto-scaling, self-healing Kubernetes cluster. ⚡️ [ YouTube ] : youtu.be/uh4V2IjSrlI [ Github ] : kutt.it/KubeAsp 〰️〰️〰️〰️〰️〰️ #Kubernetes #DotNet #Core #AspMvc #AspCore @ProgrammingTip

To DDD or not to DDD❓What to do if your domain is boring❓ "DDD should only be applied to complex domains!" - you've probably heard that over and over again. But what exactly does a complex domain look like❓ When does a domain become complex enough to justify the extra cost of applying DDD❓ And why does DDD have to be so expensive❓ In this talk, I'll challenge some of the DDD common myths, ask a few hard questions and explore what is possible when you stop blindly following what is deemed "the best practice". ✨ I'll share with you a few patterns that you can apply even to projects that are not DDD all the way just yet. You'll walk away with practical knowledge that you can start using right away. 💎 [ YouTube ] : youtu.be/h6WvetICeo4 〰️〰️〰️〰️〰️〰️ #DDD #DomainDrivenDesign #Conference @ProgrammingTip

Elasticlunr.js ⚡️ Elasticlunr.js is a lightweight full-text search engine developed in JavaScript for browser search and offline search. 🔍 Elasticlunr.js is developed based on Lunr.js, but more flexible than Lunr.js. 🔥 Elasticlunr.js provides Query-Time boosting, field search, more rational scoring/ranking methodology, fast computation speed and so on. 💎 Elasticlunr.js is a bit like Solr, but much smaller and not as bright, but also provide flexible configuration. ✨ [ Website ] : elasticlunr.com [ Github ] : github.com/weixsong/elasticlunr.js 〰️〰️〰️〰️〰️〰️ #JavaScript #Search @ProgrammingTip

Superstruct 🔥 A simple and composable way to validate data in Javascript. ✨ Superstruct makes it easy to define interfaces and then validate JavaScript data against them. ⚠️ Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API. 🧠 But Superstruct is designed for validating data at runtime, so it throws (or returns) detailed runtime errors for you or your end users. 👥 This is especially useful in situations like accepting arbitrary input in a REST or GraphQL API, but it can even be used to validate internal data structures at runtime when needed. ✅ [ Github ] : kutt.it/SprStr 〰️〰️〰️〰️〰️〰️ #JavaScript #Validation @ProgrammingTip

The Difference Between SHA-1, SHA-2 and SHA-256 Hash Algorithms 🔐 If you have heard about “SHA” in its many forms, but are not totally sure what it’s an acronym for or why it’s important, we’re going to try to shine a little bit of light on that here today. 🌈 Before we can get to SHA itself though, we need to run through what a hash is, and then we’ll get into how SSL certificates use hashes to form digital signatures. 🌐 These are critical concepts to understand before you’ll be able to follow what SHA-1 and SHA-2 are. ☝🏻 [ Article ] : kutt.it/sha256 〰️〰️〰️〰️〰️〰️ #Hash #Encryption #Cryptography @ProgrammingTip

JSON API .NET Core ✨ A framework for building json:api compliant web APIs. 💎 The ultimate goal of this library is to eliminate as much boilerplate as possible by offering out-of-the-box features such as sorting, filtering and pagination. 🗂 You just need to focus on defining the resources and implementing your custom business logic. 👌🏻 This library has been designed around dependency injection making extensibility incredibly easy. 💉 [ Github ] : kutt.it/JsonApiCore [ Documentation ] : json-api-dotnet.github.io 〰️〰️〰️〰️〰️〰️ #AspMvc #AspCore #DotNet @ProgrammingTip

Oh shit, git❗️ Git is hard: screwing up is easy, and figuring out how to fix your mistakes is fucking impossible. 🤷🏻‍♂️ Git documentation has this chicken and egg problem where you can't search for how to get yourself out of a mess, unless you already know the name of the thing you need to know about in order to fix your problem. 🤦🏻‍♂️ So here are some bad situations I've gotten myself into, and how I eventually got myself out of them in plain english*. ✅ [ Website ] : ohshitgit.com 〰️〰️〰️〰️〰️〰️ #Git #SourceControl @ProgrammingTip
