Lin zida has all birds and birds. in the virtual world of the network, someone loaded the software into a backdoor to get more bots for remote control. Although the protection software installed on your host, such as Skynet and 360 security guard, can effectively prevent backdoor startup, it will also intercept normal software. In order not to allow users to use the backdoor software with a hard scalp every day, the author hereby provides a set of methods to manually
(A) Why do we need to separate the simulated and numerical fields?Answer: both analog and digital signals need to flow back to the ground, because the speed of digital signal changes is fast, so the noise on the digital ground will be very high, analog signals require a clean reference. If the analog and digital fields are mixed together, the noise will affect the analog signal. Generally, the simulated and numerical locations must be separated and th

We know that the responsibilities of the MVC project are clear, compared with ASP. for net webform, the business logic of the MVC project is well separated from the page display. This method has many advantages, such as testability and scalability. However, in actual development, the number of controller controllers increases as the project scale expands. If there are more than two-digit controllers under the controllers folder, even if you adopt good naming rul
Writing unobstrusive code means completely separating HTML content: the data comes from the server, and javascript code is used for dynamic and interaction. The advantage of this separation is that different browsers can be fully degraded or upgraded to provide richer interaction for advanced browsers, browsers that do not support advanced features can downgrade the part they support.I.

During this rough walkthrough of spark, we haven't talked about how to use spark in a separate application. Aside from the interactive run, we can connect spark in Java,scala or in this Python program. The only difference from connecting spark in the shell is that you need to initialize the Sparkcontext yourself in the program.The process of connecting to spark varies by language. In Java and Scala, you can add a dependency on Spark-core to your appli
ObjectiveOriginally the previous article is intended to write a separate data layer, but in the process of thinking about the separation of data layer, there are some operations to rely on distributed locks, so first write a distributed lock.For some projects the data layer provides the business interface (return the data required by the business), then when the pressure of the data layer increases gradually, when the need to use the cache, the develo

Most of the time, we will encounter a lot of small projects in a git repository, but as some projects become more demanding or market demand, we need to pull them out and be maintained and developed as a separate project.
However, if the direct copy file is pasted into the new Git repository, the original commit will be discarded, so we cannot do so rudely.
What do we do? The following will be explained in detail according to an example.
