Hardware firewall is an important barrier to protect the internal network security. Its security and stability, directly related to the security of the entire internal network. Therefore, routine checks are important to ensure the security of a hardware firewall.
There are many hidden troubles and faults in the system before the outbreak of such or such a sign, the task of routine inspection is to find the
OverviewStarting with Android 3.0 (API L11), Android is starting to use hardware acceleration for 2D rendering, hardware acceleration means that graphics images drawn on the view in Android are drawn using the GPU, using hardware acceleration and, most of the time, making the drawing smoother, But the cost of paying is to consume more memory resources.Hardware ac
Some of the world's most popular open source hardware platforms! I don't know, it's out!With the promotion and popularization of the internet of things, there will be 20 billion smart devices in the world in five years, and now with the rise of the concept of creators, open source hardware is increasingly hot, let us look at what is now the mainstream open source hardwa
The booming of the Internet, the creation of the content of hardware development marathon in the world, attracted a lot of hardware talent, Chong and the popularity of smart phones from the coding trend of the hacker marathon in the global popularity, called the Programmer's "American Idol", a group of software development experts gathered a hall, Dozens of hours to develop a plug-in or decipher a program,
When talking about the hardware configuration file, many friends ignored its role in Windows XP. In fact, if it is used properly, it can greatly improve the efficiency of the system.What is a hardware configuration file?
The hardware configuration file refers to a series of commands that tell Windows which devices should be started and which settings of each devi
When doing the project, the Guide page of the Viewpager reported Oom exception, the picture is not big, in the manifest file application node added two lines of code to solve the problemAndroid : hardwareaccelerated= "false"Android : largeheap= "true"Starting with Android3.0 (API level 11), the Android 2D rendering pipeline provides better support for hardware acceleration. All of the drawing operations performed by
What is the level of technical requirements for hardware engineers?Of course, from the childhood education we know that knowledge to understand thoroughly, the deeper the better, for any one point of knowledge, through the basic formula, using mathematical tools deduced to the last to verify the advanced laws and formulas. I think for this point, the college Entrance Examination physics is reached the pole, high school physics knowledge is not difficu

1. Identification of hardware in Linux;
In the linuxsir. org discussion area, we often see some brothers describe their hardware as follows: "My display card is made of XXX brands. What should I do if Linux does not support it ?". In fact, this is the worst description, and there is no
Linux users do not know a bit about the manufacturing of open source hardware, they often fall into the mood of disappointment.Business software and freeware software have been entangled for many years, but these two often misunderstand each other. It's not surprising-it's business for one side, and the other is just a way of life. But this misunderstanding can be painful, and that is why it is worth the effort to expose the inside.An increasingly com
Tencent Computer Butler a very good security protection software, and, it also has the hardware detection function, can let the computer hardware information at a glance. Open QQ Computer Butler main program, click on the QQ computer Butler's "Hardware Detection" in the "toolbar", will automatically detect hardware inf
In the last two articles, we described how to write drivers for the hardware of the Android system, including how to implement kernel drivers in the Linux kernel space and implement hardware abstraction layer interfaces in user space. Both are implemented to provide hardware access to the upper tier, providing hardware
information Demand analysis of hardware industry"Domestic competition internationalization, international competition and domestic" will be the characteristics of the development of China's hardware industry in recent years, China as the Global Hardware Manufacturing center status will be further stable. China has become the most dynamic economic region in the wo
Today, the recycling work has been 2 months, has been on business, repair equipment, change a core board, change a power supply and so on. The feeling learned very little, originally was a hardware engineer assistant recruit come in. Now do what, basic continuous travel, nothing learned. This is not deceptive, think, their current economic situation, can only parasitic in the next. But knowledge, self-study is very fast. So looking at some of the
Enable hardware acceleration What does it mean to play games and watch movies faster or slower after you enable hardware acceleration, which is turned on by default and how to turn off hardware acceleration.
In short, hardware acceleration is the use of hardware modules to
In short, the hardware abstraction layer of Android encapsulates the Linux kernel driver and provides interfaces up to shield implementation details at the lower layer. That is to say, the hardware support is divided into two layers: one layer in the user space and the other layer in the kernel space, where the hardware abstraction layer runs in the user space, t
Add the hardware abstraction layer (HAL) module on Ubuntu to access the Linux Kernel Driver (Lao Luo study note 3) and ubuntuandroid
In the overview and learning plan of the hardware abstraction layer (HAL) of Android, we briefly introduce how to write a driver for the hardware in Android. To put it simply,Hardware dri
The first time to do intelligent hardware, without all kinds of pit, but in this process is also gradually explore a more intuitive intelligent hardware abnormal case to check the method, through this method I combed out of the exception than the engineer reported to me a comprehensive, pro-test available, you may wish to try.

Ashamed to say that, based on the arm of the platform for such a long time, has been busy in the kernel, very little understanding of the development of the application-related, and did not contact the HAL and Dbus. Because the top o
There are two clocks of hardware clock and system clock in Linux. The hardware clock is the clock device on the motherboard, which is usually the clock that can be set on the BIOS screen. The system clock refers to the clock in the kernel. All Linux-related instructions and functions are programmed to read the system clock. Because there are two different clocks, there is a difference between them. When Lin
