Y480 is Lenovo a highly cost-effective game audio-visual book, especially students to start quite a lot, and its performance really let people very satisfied, the following say our machine problem, have a lot of friends are looking for Y480, but small series of search for half a day only the friends will release a few pieces of disassembly diagram, turn on a few , personal feeling help is not very big, you are welcome to say is very easy to mislead, Y

0x00 PrefaceThe static disassembly King, without a doubt, IDA Pro, greatly reduces the threshold for disassembly, especially the excellent "F5 plug-in" Hex-rays can restore the assembly code to a C-like pseudo code, greatly improving readability. But personally feel that "F5 plug-in" can only be used as an auxiliary means, after the combination of dynamic debugging and static analysis, understand the whole
2014 can be said to be the rapid development of the game industry, and experience a change in the year. Not only Sony PS4, Microsoft Xbox One two new game host has been officially listed, some years ago can not achieve the technology is expected to develop and grow this year, such as the cloud gaming platform, augmented reality experience, and so on, below to understand.
I. Cloud platform and streaming technology
Cloud, streaming form
while PS4 and Xbox One are always playing in the game field, don't forget that PC games are a force to be reckoned with. At the same time, for PC gamers, there seems to be no need to obsess about how to choose between PS4 and Xbox One, as host players do.
But for PC players, how to choose the graphics card is also a learning, any one on the DIY desktop has experience, will have their favorite

television to get outside information.2, today's consumer consumption of the mainstream content, a large part of the existence of the Internet, and no longer the previous TV channels and television. Traditional TV channels are lagging behind the reception of content.3. As one of the most popular categories of consumer content, the living room games that have tried on traditional television have now hatched a more professional device: consoles such as Xbox and
phones and other devices. Share. For example, your mobile phone can connect your mobile phone to another Sony, or connect to the TV through miracast, or connect to the car audio through the audio link. A unique feature is to connect Z3 to PS4/3 through OTG and Bluetooth, so that the control controllers of PS4 can be on mobile phones. There are many games that you can run up through the controllers, I sudde

The-x option returns the command line result after parameter replacement, command replacement, and other command line processing steps. The x option prints + at the beginning of each line (but I don't know why I printed two). This can be customized. It is the value of the built-in shell variable PS4. You can modify this symbol by modifying the PS4 value. For example, the c
April 25 News, Microsoft officially announced on May 21, the next generation of Xbox game Host Conference. Although there are still one months to see its ticket, but based on the previous channels of coverage, we have been able to roughly describe the outline of the mainframe. Below we will summarize this by Netizen called "The Xbox 720" The game machine the general situation.

Virtual Machine-Based Software Protection TechnologyGuideVirtual Machine-based software protection technology is not sure whether it is first proposed by vmprotect, but vmprotect is undoubtedly to promote this technology to people. Nowadays, virtual machine-based software protection technology has become one of the essential functions of modern software security protection.
This article does not intend to discuss vmprotect or another software condom in depth, but focuses on the origin, idea and
entered by the user to an array is only to create a buffer overflow vulnerability and to facilitate subsequent discussions. In reality, such a situation may be difficult. However, the principle is the same. The buffer overflow vulnerability occurs because it fails to detect the size of the data to be copied and directly copies the data to another buffer zone, this gives malicious programs the opportunity to attack.
Iii. Analysis of vulnerability principles
Whether it is the simplest buffer ove
finally calls. In this case, let's take a look at what is followed by so many 41414141.
Pay attention to the stack growth direction from high address to low address. From the perspective of 41414141, 00000000 01b8a000001b99fe8 should be ebx esi and edi. Continue to see ffffffff 0012e3bc. (Why, because this is obviously not the return address. 0012e3bc is within the range of the stack where the function fails, and it cannot be the return address.) The next step is 0050a1d4, which is probably
