当今最新最先进的讨算机反病毒技术，有实时扫描技术、启发式代码扫描技术、虚拟机技术和主动内核技术等。
Nowadays there are some new and advanced anti-virus techniques, such as real-time scanning, heuristic code scanning, virtual machine and active kernel technique etc.
TCPTR在内核级别主动地管理到达的套接字连接请求，允许迁移透明地工作——不需要修改现有的应用程序(见图1)。
TCP tr actively manages incoming socket connection requests at the kernel level, allowing the mitigation to work transparently - requiring no change to existing applications (See Figure 1).
内核社区应该主动出击，帮助大家消除这种恐惧。比如，可以帮助Android看看能不能换用GPL授权的代码。
The community should be more proactive on this front to allay fears; pointing to Android as an example of how GPL-licensed code can work is one possibility.
这不是像RedHat一样的公司总是主动把他们自己的研制成果提供给Linux内核项目中心存储库的唯一理由。
This isn’t the only reason why a company like Red Hat would offer their own development to the central kernel project repository.
设备驱动模式，在设备须要内核关注时，由设备主动发送一个硬件信号(通常是通过一个中断)给内核。
Driven on the device side. The device sends a hardware signal (by generating an interrupt) to the kernel when it needs the kernel's attention.
内核驱动模式，由内核有规则的主动检测设备的状态，看设备是否有内容要输出。
Driven on the kernel side. The kernel checks the device status at regular intervals to see if it has anything to say.
