ctf hacking

Thanks to several hackers, firmware 2.0 and below can use the "partially" GPU (NVIDIA rsx) feature. Recently, I have spent a lot of time on this and have a rough understanding of the GPU underlying layer and tool chain. On the PS3, there is an operating system at the bottom layer that provides hardware functional interfaces, which is called Level 1. Any operating system on it needs to interact with the hardware interface through level 1 API, which is called Level 2. With this concept, the d

The general is to find the site backstage, network management of personal information, can also be used to find someone on the network activities. Google Hacker is generally done as a means of hacking at the time of the invasion. In the intrusion process sometimes need to find the backgro
