This series of videos covers of the the most important concepts related to system design, with a focus on practical system design knowledge for interviews. These system design videos cover topics like vertical vs horizontal scaling, load balancers, database design and scaling, caching, back of the envelope math for estimating capacity requirements for a system, an introduction to distributed systems, and some system design interview style questions walking through a full design implementation

 

In this article, we will learn how to write automated tests on web APIs with Postman. In order to follow along to this tutorial, you’ll need at least a fair amount of familiarity with Postman. 

JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime. Unlike other cross-compiler tools targeting JavaScript, JSIL produces readable, easy-to-debug JavaScript that resembles the code a developer might write by hand, while still maintaining the behavior and structure of the original .NET code.  Demo

How do callbacks, promises and async/await compare to each other? This article shows the same scenario using each of these three techniques so you can see the differences and choose which appeals most to you. 

In this article I’ll teach you how to use CSS Grid to create a super cool image grid which varies the amount of columns with the width of the screen. 

In this post, I'll talk about what the different things I've made on this website to improve the performance. Some of the optimizations are just some configuration flags to turn on, others require more changes in your code.

• Enable HTTP/2
• Enable TLS 1.3
• Compress responses using Brotli or gzip
• Add caching information
• Optimize JavaScript / CSS files
• Reduce the number of redirections
• Optimize images
• Move your servers near your visitors (GeoDNS, CDN)
• Resource Hints: Prefetch resources
• Remove unused resources / features
