Pikachu vulnerability range series brute force cracking
Foreword This is the first article in the Pikachu vulnerability shooting range series~~ (it should be serialized)~~. First, let’s briefly introduce the Pikachu shooting range. This shooting range was developed by Chinese people and is purely in Chinese. If you encounter difficulties during practice, you can check the tips. There are also supporting learning videos. […]
Strange Towers of Hanoi (Strange Towers of Hanoi)
Description Background Charlie Darkbrown sits in another one of those boring Computer Science lessons: At the moment the teacher just explains the standard Tower of Hanoi problem, which bores Charlie to death! The teacher points to the blackboard (Fig. 4) and says: “So here is the problem: There are three towers: A, B and C. […]
Orange Pi (orangePiZero2) 2: Driver development, writing code to control the level of the IO port
1. View the chip manual Go to the official website to download the chip manual and view the manual. 1. As can be seen from the chip manual, the base address of GPIO (0x0300B000): 2. You can see the PC offset (0x0048) from the chip manual: The address of GPIOx is the GPIO base address […]

Enhanced Map in Guava – Table, BiMap, Multimap, RangeMap, ClassToInstanceMap
1. Introduction When using Map in daily development, we often encounter many complex processing scenarios, such as: Map with multiple keys, not only the value can be obtained based on the key, but also the key can be obtained based on the value without traversing, Map with repeated keys, numbers and other ranges Mapping the […]
[Allwinner H616 uses the standard library to complete the self-made serial port library (implemented in separate files) orangepi zero2 (open source)].md update: 23/11/07
Article directory Note when playing with H616: Linux kernel version 5.16 and above, you need to manually configure the i2c-3 uart5 driver Configuration example When compiling by files, each file must be compiled together (separated by spaces) Example: ggc a.c b.c b.h -lpthread -lxxx..; Common commands View driver files View kernel detection information/hardware Use the […]
