Projects under the solution often need to unify the generated assembly version numbers in the simplest way, of course, by opening the AssemblyInfo.cs file modifications under each project, or by using the project property modifications. Recently, there is a much simpler way to find out, and to introduce it carefully below. Step 1, create a SolutionInfo.cs file, and put it under the solution. The content is
Genetic algorithm is a bionic algorithm, used to obtain the satisfactory solution of some problems, I feel this algorithm is very interesting, wrote this program (later hand over the big homework). Source code: HTTP://PAN.BAIDU.COM/S/1BOSWRIF The following copy from Baidu Encyclopedia: Genetic algorithm (genetic algorithm) is a computational model of evolutionary process that simulates the natural selection and genetic mechanism of Darwinian evolution
As you know, Namenode has a single point of failure in the Hadoop system, which has been a weakness for high-availability Hadoop. This article discusses several solution that exist to solve this problem. 1. Secondary NameNode principle: secondary NN periodically reads the editlog from the NN, merging with the image that it stores to form a new metadata image advantage: The earlier version of Hadoop comes with its own, simple configuration, Basic no ad

is too low. Computer hardware failure is usually a hard drive failure, the author of this situation before the computer, the computer is more and more card, sometimes the network cable broken, reinstall the system, the problem is still, in the local play music, often occasionally intermittent, after the detection of the computer hard drive in a lot of bad way. After the replacement problem resolution, the computer speed significantly improved a lot. The s

size under the/home directory, after I log on to the Linux database server, use the DU-SH command to see the/home directory size of 250GB. The first of these solutions: You can see that the users table space has a total of 3 dbf (at this point I have added 04.dbf), copy one of the DBF path/home/oracle/oradata/users01.dbf, overwriting the following datafile parameter: --A new DBF file is added, specifying that the DBF file size is around 32GB, and that it automatically expands 1GB each time, and
DDL), Share DDL Locks (Shared DDL Lock), breakable parse Locks (can be broken by parsing locks). The space is limited, here is no longer detailed introduction. According to this example, when we try to compile, modify stored procedures, functions, packages, etc. to the data object, if others are compiling or modifying them will create a lock wait, or when we compile a stored procedure, if it refers to the database object is being modified should also produce a lock wait. This hypothetical sibli
MySQL High-availability solution (MySQL HA solution)What is high availability?Many companies have 24 hours * 365 days of uninterrupted service. Call Center, for example. This requires high availability. Another example is the shopping site, which must be traded at any time. Then, when the server of the shopping network hangs one, it cannot have any impact on the business. This is high availability.High Avai
A * algorithm can be used for pathfinding of a single unit. However, in practical applications, multiple units are often moved at the same time, and they will affect each other and hinder the movement of each other. So once the conflict, the path calculated for each unit will be invalidated.A popular solution is to recalculate the path when a conflict is found. There are regular recalculation and so on. These are dynamic adjustment schemes, and the re
This article describes the detailed solution for Java memory overflow. This article summarizes two main cases of memory overflow, and the JVM often calls the garbage collector to solve the problem of insufficient memory, but sometimes there are still low memory errors. The author analyzes the composition of the JVM memory area and the way the JVM sets up virtual memory, and gives a series of solutions.One, memory overflow type1. Java.lang.OutOfMemoryE

Open My Computer, click Add/Remove Program in the left navigation of my computer, if not, you can click Add/Remove program from the Control Panel. 2, then the upper right corner of the display update before the tick, and then pull down to find Windows Internet Explorer 8-Software update (KB2847204)
The system will face a large number of user access after the official launch, facing high concurrent requests at various levels, so we will adopt high-performance server, high-performance database, high-efficiency programming language, high-performance web container and so on. But in these areas, it is not possible to fundamentally address the high-load and high-concurrency problems faced by large web sites. Therefore, we must make corresponding strategy and technical
Presumably a lot of friends in the UTF8 encoding php development upload function, will encounter such a problem, that is, uploading Chinese file name files, filenames will become garbled, in fact, we can use the Iconv function to re-encode the file name to solve the problemmay have a lot of friends encountered some problems is to upload the file if the original name is not a problem, if it is Chinese may appear garbled, today I come to you to summarize the cause of garbled php upload file Chines
