How Query Optimizer Works in RDBMS
In a previous post, we discussed how the various relational operators are implemented in relational database systems. If you have read that post, you probably still remember that there are a few alternative implementations for every operator. Thus, how should RDBMS determine which algorithm (or implementation) to use? Obviously, to optimize the performance for any query, RDBMS has to select the correct the algorithm based on the query. It would not be desirable to always use the same algori...

The Most Effective Stretches and Yoga Poses for Programmers
Programming software takes a tremendous amount of focus and effort. Working hard to transform code into software is an exciting feeling. It’s easy to get lost in your work as the hours fly by. I’ve done this many times. However, writing code can also be frustrating in many cases. I’ve been a programmer for many years, and I still spend hours debugging. Most of the time this level of debugging requires sitting down and focusing. After many years of this, you will be a prime ca...

Introduction to the Application of eBPF in Golang
Most of the time, when we develop software or even use software, we play within the safe boundaries of the operating system. We might not know how the network interface welcomes that IP packet, nor how the filesystem handles the inodes when we save a file. This boundary is called user space, which is where we write applications, libraries, and tools. But there's another world, kernel space, where the operating system's kernel resides and is responsible for managing system resources such as memor...

New Unreal Engine 5 and Nvidia Technology in Black Myth: Wukong
In this article, we explore the cutting-edge Unreal Engine 5 and Nvidia GPU technologies used in the highly anticipated AAA game Black Myth: Wukong this year to enhance its game graphical quality. Our insights are based on an interview article of the technical lead of Game Science Interactive Technology, Geekerwan's experimental analysis, and Nvidia's official Black Myth: Wukong showcase featuring the RTX 40xx series. As a software engineer, my perspective may differ from that of a game develop...
The four key figures behind the success of JavaScript - Douglas Crockford
JavaScript's success can be attributed to at least four key figures: Brendan Eich, the creator of JavaScript Douglas Crockford, the creator of JSLint and JSON John Resig, the creator of jQuery Ryan Dahl, the creator of Node.js. We are already very familiar with Brendan Eich and the invention process of JavaScript, so let's start with Douglas Crockford, the second in command of JavaScript. Alliance In the 1990s, Microsoft's dominance overshadowed the whole world. At this time, two challengers e...
