  When and How to Use the Go Channel

Go’s concise structure and powerful native library enable us to hit the ground running easily. It is more efficient than Java or Python when implementing the same functions, especially its concurrent programming, which is very handy and widely admired due to its goroutine and channel. goroutine and channel has much to dig into, and let’s start with channel, which I used to consider narrowly as a message queue to transfer data between gorouti...

  php://input in PHP

When using xml-rpc, server side will get the data from client with php://input method instead of $_POST. Hence today we will discuss php://input. PHP official manual has below explanation to php://input: “php://input allows you to read raw POST data. It is a less memory intensive alternative to $HTTP_RAW_POST_DATA and does not need any special php.ini directives. php://input is not available with enctype=”multipart/form-data”. Here we und...

  Applying Large Language Models (LLMs) to Solve Cybersecurity Questions

In this document, we will introduce some test, experiment and analysis conclusion about applying Large Language Models (LLMs) to solve cybersecurity questions. Introduction Large Language Models (LLMs) are increasingly used in education and research for tasks such as analyzing program code error logs, help summarize papers and improving reports. In this project, we aim to evaluate the effectiveness of LLMs in solving cybersecurity-related questions, such as Capture The Flag (CTF) challenges, ...

  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...

  Asus ZenBook 3 vs MacBook: Has Apple Met Its Match?

With its upcoming ZenBook 3, Asus is the latest company to compete with Apple's superthin 12-inch MacBook. Due out later this year, the 12.5-inch laptop is even slimmer than the MacBook and one-ups Apple's offering with a faster CPU and a range of fashion colors. Though we haven't been able to test the ZenBook 3 in our labs yet, we've studied the specs and spent some hands-on time with the slim system to learn about its capabilities. So based on what we know today, which superslim not...

  Significance and use of do{...}while(0)

In some Linux kernel and other open source codes, we can see some codes like below: do{ ... }while(0) This code snippet is not a loop, it seems there is no significance of using do...while this way, then why should we use it? In fact, the significance of do{...}while(0) is better than optimizing your code. After some research, we summarize some benefits of it. 1. Help define complex macro to avoid error #define DOSOMETHING()\ foo1();\ foo2(); The me...

  Publish Your Go Package on pkg.go.dev

go.dev is a site where various resources for Go developers are shared, such as “Get Started”, Tutorial, Packages (pkg.go.dev), and all the official blogs. Among them, Packages is where I visit most, which allows free access to all the open-source Go packages submitted by communities including the native Golang packages. Thanks to all the contributors, I enjoy the great benefit, and sometimes I want to be a contributor myself. Let’s submit a “complete” package t...
