just that. Next, you need to learn a bit of hardware knowledge, for future Linux OPS engineer is very helpful. The core parameters of the hardware such as memory capacity, speed, parity and so on the judgment, CPU manufacturing process, internal and external cache, etc. need to be well known.Linux learning needs to explore their own learning, starting from the basics of basic knowledge, slowly understand the essence of Linux, the basic architecture, design principles, do not too slow, do not fe

Write a blog for the first time and share a software that was done a long time ago.Do this reason is to participate in a teaching team before, found a lot of problems, feel that using software can reduce a lot of unnecessary trouble, so nothing to learn while doing, finally did not think of also do have a model, hooves O (∩_∩) o haha ~With Java and MySQL can be used on Windows systems, the installation of the database is troublesome, the others are very simple.　　The interface and functions are a

For some Python functions, sometimes we only use one or two times in very few cases, but we need to name the function names when we define them, and we can simplify the code by using lambda without having to consider naming problems.Example:The following function calculates twice times the X >> def doublex (x):Return 2 * x >> DoubleX (5)10>>is to use lambda to become>> g = Lambda x:2 * x//LAMBDA followed by parameter name, colon followed by return value>> g (5)10>> Two examples

It was just one months before the computer was contacted.Learned the Java,javaweb. Java just learned the basics of the chapters, many of the topics did not do, just understand some of the basic things. Because want to have some knowledge of these things earlier,
