Lately, I’ve been working on a project related to recording Linux kernel execution traces at the object code level. During this process, I had the opportunity to work with the ARM64 architecture on Linux. I decided to write this blog to capture some of the highlights I learned along the way.
When using the Linux command line and related tools, there are many useful tricks and common practices worth noting. In this post, I’m keeping a running list of tips related to Linux command-line tools for future reference.
This blog presents a growing collection of papers and tools related to the topic of kernel testing. I (hopefully ;p) plan to update it regularly, since I want it to serve as a handy index whenever I revisit this topic.
This blog presents a growing collection of papers and tools related to the topic of symbolic execution. I (hopefully ;p) plan to update it regularly, since I want it to serve as a handy index whenever I revisit this topic.
Lately, I’ve been trying to record assembly execution trace of QEMU emulations. To grasp a better understanding of this process, I decided to take a look at the source code of QEMU, accel/tcg/cpu_exec.c in particular. As I’m reading the source code, I write this blog post as a review of what I’ve learnt from it.

As a popular SVN, Git appears in almost every developper’s toolkit, regardless of what type of projects they are working on. Git provides us with a convenient way to keep track of all the changes made to a project, so that we can easily revert the project back to certain states if errors occur.
Failed to open the terminal on your ubuntu system after upgrading python3 version? Here’s a way to potentially heal your pool command line!
This is a series of notes for course CS 161: Computer Security held by UCB. I watched the recordings of its Summer 2021 version during winter holiday, 2023. The course website can be found here. After that, I took ECE 422: Introduction to Computer Security in UIUC during Spring 2023, the course structure was roughly the same as CS 161.
As a beginner of reverse engineering, I spent three days in the spring break to work on a single CTF problem…
