see, there are a total of 16 interrupt lines: EXTI0 to EXTI15.
Each interrupt line corresponds to a total of 7 GPIO from Pax to PGX. That is, at the same time each of the disconnection can only be corresponding to a GPIO port interrupt, not the corresponding all the port interrupt event, but can be time-sharing, in the program execution process, this does not need us to care too much. The most we care about is the way the interrupt is triggered :

SELinux is bypassed again
The security researcher Sebastian Krahmer of GNU/Linux vendor SUSE Linux again bypasses SELinux after publicly bypassing the PoC of SELinux's CVE-2015-1815, this public PoC can work normally in CentOS 6.6, in 6.8 and 7, because RHEL and CentOS share the same code, Sebastian believes that part of The SELinux kernel code is of good quality, but the user space framework is huge and has many defects, setroubleshoot is a daemon process written in python that will be activat
June 17 is Apache Karaf as Apache top project. Karaf is a run-time package that contains an OSGI framework (Equinox or Felix), a command shell (Felix Gogo), and a number of utilities built into it by default.Although Equinox and Felix can be used alone, the KARAF is designed to combine the excellent OSGI capabilities of both frameworks and ensure that they are out of the box. For example, it contains a configurable log system (based on log4j, but is packaged for many common logging systems), rem

limited disk space requires reasonable management of massive data storage. In fact, the solution to this problem is to maximize disk space utilization.
Strong adaptivity to highly dynamic workload patterns
The same data set is provided to users of different applications for analysis in various ways. Some data analysis is a routine process that is periodically executed in a fixed mode, while others are queries initiated from the intermediate platform. Most loads do not follow any rule mode. This
need to have separate kernels and other system files, so as long as you install what you need on top of it, will we need Python to run the Go service? This is not a difficult question to answer.
Micro-base image
First we want to abandon the idea of using Ubuntu or Debian as a base image, and we look at lighter choices.
Alpine Linux is a miniature Linux distribution that can be used to build a base container with a volume of only 5 m, which is based on an embedded system BusyBox transformation.
