went to the class with my boyfriend to study Liu Yan Teacher's course. After studying in the newspaper class, we learn more systematically than before. And, of course, there are more topics to discuss with my boyfriend. We also often quarrel with each other because of the problem of anger and good, and in such a process, my boyfriend and I also warmed up a lot of feelings.After graduating last year, through the school recruit boyfriend in a network company engaged in operations development work

Syslog log systemThe second is to use file to customize the log information saved filesNote: A category can use multiple channel to save log information, but a channel can only hold one category log source information.The DNS log system needs to be defined in/etc/named.conf.For example, define the DNS log system format as followsLogging {Channel My_query {File "/var/log/named/log.query" versions 3 size 10k

The learning plan for the embedded Linux operating system is clear, and the most important thing is the recommended books. If you plan to enter this line of development, you must learn everything !!!The arm + LINUX route focuses on the embedded Linux operating system and its application software development goals:(1) master the structure and principle of mainstre

philosophical ideas exist, recorded under the understanding of the Linux operating system philosophy.All documents (Linux almost all the resources are abstracted into the form of files, even the hardware, network communications using sockets and pipelines are so), the file is a set of boundaries in the storage device streaming data.Second, by a number of small functions of a single program, combined together can achieve complex tasks, each small prog

Sendmai and qmail services to build mail servers, using NFS and iSCSI to build network storage server, Linux in the enterprise application of a very wide range. Linux supports multiple users, each user has their own special rights to the file device, to ensure that the user does not affect each other. Multitasking is one of the most important features of computers now, and Linux allows multiple programs to run simultaneously and independently.In the network devices are generally Linux operating

Many new users learn embedded systems, but do not know where to start learning so much steering knowledge and reference books. When I started, I lost my direction when I learned what to do first. Here is the answer you want to give you some advice. This is the course outline I found on the itjob training network. I think it is a good learning method to implement and learn embedded

*/ Write Efficiency test results:After adding a custom buffer, the test found that its efficiency was 100 times faster than the non-self-defined buffer, and that the write rate of the marked C was several multiples faster. If the buffer size is appropriate, its efficiency will increase even more. So when we change Buf_szie to a larger value (buf_szie=50000), after recompiling, the test results are as follows:This efficiency is improved, so choosing a suitable buffer is especially import

I like to work based on web apps. It is very attractive to implement an application that can be run from anywhere and on any device. Over the past few months, I've been trying to get some basic lightweight machine learning algorithms that run on JavaScript and then use them to build " smart " Web apps. With the advent of node, it is possible to train the model on the server side and then use these models to make predictions on the client. I've researc
