Compared to several other community distributions, the fuel version is fast-paced and provides a relatively stable community version every two months.

FindBugs functionOnce a developer has developed a portion of the code, you can use FindBugs to check for code defects. Improve the quality of your code, but also reduce the number of bugs that testers have reported to you.
The static analysis tool promises to find bugs that are already in the code without the hassle of a developer. Of course, if you have many years of experience in writing, you will know th
Valgrind is a GPL 'd System for debugging and profiling Linux programs. with valgrind's tool suite you can automatically detect into memory management and threading bugs, avoiding hours of frustrating bug-hunting, making your programs more stable. you can also perform detailed profiling to help speed up your programs.Why shoshould you use valgrind?
Valgrind will save you hours of debugging time. with valgrind tools you can automatically detect into
This article only describes how to find bugs, but lists my usage over the years. NET programming process to find some methods of bugs, you are welcome to follow the post, your understatement may be able to lift some of the people's long-standing confusion.
It is common to write programs with bugs, but they have various forms. Some of them can be seen directly, so
There are many definitions of lean, but one of the most encouraging is that the Lean Enterprise Research Institute chairman John Shooke in his book, "Management Lean", described in the passage: lean by improving the level of staff to ensure product development. On the basis of this definition, this paper then explains how lean improves the level of people: the way to solve problems. This definition reveals the beauty of the following management practices: Carefully design your work so that you c
Twitter throws a discussion topic: In the afternoon, a test lead asks that some bugs will appear in a version, and then record it, but developers reject it when the current B version attempts to reproduce. Then the test is depressed, until the next round of regression test may be the C version D version, if the natural reopen, but if not reproduced whether it should really turn off it. How do you deal with this sometimes bug?

First, what is OpenStack?OpenStack is an open-source cloud management platform project that combines several key components to do the job. OpenStack supports almost all types of cloud environments, and the project goal is to deliver a simple, massively scalable, rich, standard, unified cloud management platform. OpenStack
purpose of this article has been achieved. Because this article describes the implementation of dynamic migrations on the OpenStack platform, readers must have a certain understanding of OpenStack.Introduction to Virtual machine migrationDynamic migration consists of two meanings, one is migration (migration), and migration is to move a user's virtual machine from one physical host to another. The second is dynamic, the dynamic meaning is in the proc
