The C \ S and B \ s systems with persistent connections have inherent defects. The occasional Connection System (OCA) attempts to solve these problems while introducing new problems. There are many challenges in developing offline systems. These challenges are all faced by Microsoft sync framework and should provide reasonable solutions for application developers.
MSF is a comprehensive synchronization platform that enables developers to add synchro
The previous chapter introduces the concept of SQL azure Data sync. This chapter describes how to use data sync.

Note: This chapter describes how to synchronize the local SQL Server 2008 R2 dB and SQL azure dB, so Install SQL Server 2008 R2 on the local machine first.
1. Use SQL Server Management studio to create databases and tables in the local SQL Server 2008 R2 dB.

MK-table-sync is a powerful tool in maatkit for synchronizing master-slave databases. During synchronization, the delete, replace, insert, and update statements are synchronized, MK-table-sync executes all the preceding statements. For example, the master and slave databases contain Table A. The data in the master database is as follows:
ID name
1 aa
2 bb
3 cc
4 dd
5 ee
6 ff
The data on the slave database i

Recently learned the mutex, read-write lock, Once, waitgroup in the Go language in the synchronization package. In the process of concurrent program development, these two kinds of locks are very important, including the time of access control for shared resources. Sync is the standard library in the Go language.

As a system administrator or Linux Power User, your may has probably come across or even on several occasions, used the VE Rsatile Linux Rsync tool, which enables users to expeditiously copy or synchronize files locally and remotely. It is as well a great tool popularly used for backup operations and mirroring.Some of its eminent features and advantages include; It's exceptionally versatile in, it can copy locally, to/from a remote shell or remote rsync, it's also remarkably Flexible, allowing u
written to disk for a period of time. In the event of a system failure, this delay may result in the loss of file update content. To ensure consistency between the actual file system on the disk and the content in the buffer cache, the UNIX system provides sync, Fsync, and Fdatasync three functions.1. Sync functionThe sync function simply queues all the modified
When you install the Windows 8 system, you will need to provide a Microsoft account and password for the system login (or set to log on as a local account). In addition to logging on to the system, the account can also log in to your SkyDrive, App Store, mail account, Office 2013, and other general-purpose accounts. In addition, using this account, you can log on to different computer devices, and automatically sync some of your applications and setti
Purpose Description
The Linux kernel to achieve optimal disk operation efficiency, the data that needs to be written to disk is now cached in memory and is actually written to disk at the right time, which is not problematic in most cases and improves the efficiency of the system, but if the system is machine, power off, There will be some file content that will not be saved. When the Linux system shuts down or restarts, the contents of the buffer are automatically synchronized to the disk a

Golang multithreading is easy to use, but sometimes you need to lock the data to prevent data from being changed by other threads. Then the mutex under the sync package is very useful.
A mutex is a mutex. Can be part of a struct so that the struct prevents the data from being changed by multithreading.
Here's an example:
Package Mainimport ("FMT" "

Background introduction:At present, we have more than 200 front-end servers online, each time we release new applications, we put the packages on a dedicated push server, and all the front-end servers are automatically synced through rsync. But with the number of front-end servers increasing, the bandwidth of the push server has become a bottleneck.The BitTorrent sync is a solution. At the same time, its cross-platform support is also very good, wheth
