This article describes the author's problems with using Import-spmetadatawebservicepartitiondata in a SharePoint farm environment that uses SQL Server high availability. Hope to be of help to everyone.I recently exported metadata using export-spmetadatawebservicepartitiondata from the development environment, Then use Import-spmetadatawebservicepartitiondata to import the metadata backup file into SharePoint 2013 using SQL Server High Availability In
Blockchain Development (i) building a private chain environment based on the Ethereum
Lihe 2016.07.08
Through the methods described in this article and the script, we can quickly set up their own private chain for blockchain development testing, this article is based on the Ethereum technology to build, divided into two parts, one is the Ubuntu under the construction method, the other is the Windwos under t
I've been studying ethereum blockchain for some time now, and this really makes me more excited. There is a lot of information about Ethereum (articles, videos, platform website), which we can easily get, because the platform is still fast iterative so the relevant data content generally lag. I've compiled a diagram of what ethereum is and how he works based on w
first section OverviewFor beginners, the content covers the basic concepts related to ethereum development and will teach you how to build a complete de-centralized application based on Ethereum-blockchain voting system.By learning, you will master:
Basic knowledge of Ethereum blockchain
Software environment required to develop and deploy
Golang Learning Note 19 using Golang to implement Ethereum token transfer
In the Ethereum blockchain, we call tokens tokens, which are digital assets that everyone in the Ethereum blockchain can freely distribute. And it must follow the ERC20 standard, as for the ERC20 standard, you can refer to this article Https://theethereum.wiki/w/index.php/ERC20_Token_
Blockchain Development (ii) deployment and operation of the first Ethereum smart contract

This article is starting 8BTC
There are many articles on the network that deploy smart contracts, but all have a common feature, is the command line to deploy, first build the SOLC environment, then deploy Geth or ETH node, and then step by step to generate wallets, ABI, contract address for deployment, Obscure and easy to fail for beginners,

1. Ethereum Overview
Ethereum (Ethereum) is not an organization, but an intelligent contract on the blockchain, open source of the underlying system, ethereum from the birth to May 2017, just 3.5 of the time, the world has more than 200
As cryptocurrency becomes and more popular between people. Importantly, with hight profits return, someone have increased the proportion of digital asset in their asset allocation. For those with strong faith on that blockchain technology are the first time for the human to protect their private prop Erty Cann ' t is infringed and transfer the value without any restriction by third party, is attracted by Blockchain techno Logy. At the same time, the safety of cryptocurrency are more importanter
# # What is an Ethereum smart contract? An Ethereum smart contract is a collection of code (its functions) and data (its state) that is stored in the Ethereum blockchain with a specific address. Smart contract accounts can pass messages to each other to achieve Turing complete operations. The smart contract runs on the blockchain with
5 Minute quick build Ethereum Alliance chain from scratch
In the process of developing Ethereum Dapp, a test chain is required, previously using TESTRPC or directly connected to Ethereum testnet (Ropsten), but Testrpc has a variety of pits to deal with and Ropsten Testnet is the need to synchronize and wait chunks, quite annoying. A few days ago saw parity 1.5 ve
Origin post by Vitalik Buterin, on December 24th, 2015
we have been openly continuing to improve the plan and long-term development roadmap for the Ethereum agreement for quite some time, and this has come from lessons learned from errors that were not dealt with immediately before or after the release of the 1.0 release. However, the cyclical development of the Ethereum core protocol has been restarted, th
I. Introduction to intelligent Contract IDE
Currently, Ethereum supports three languages to write smart contracts,
Solidity: Similar to JavaScript, this is the official Ethereum recommendation language and the most popular smart contract language. For specific usage, take the solidity document, address: https://solidity.readthedocs.io/en/latest/
Serpent: Python-like style, document address: Https://github.
Blockchain Enthusiast (qq:53016353)
In the Ethereum development block chain, each chunk points to the previous block, and the chunk Hashiki computed by SHA256 is the basis on which the Ethereum development ledger cannot be tampered with. In one chunk, the Ethereum development system uses trading (Transaction) to represent an
Use * * Ethereum wallet DEVELOPMENT * * To achieve the classic Helloword smart contract class. In this article, we'll see how to write a simple contract and deploy it to a blockchain. We'll also learn how to interact with our smart contracts by sending and reading data. Solidity's contract syntax is actually similar to classes in object-oriented programming languages. Smart contracts have functions that we can call and variables that can be stored and
Ethereum is an agreement that anyone, as long as they have the means, can interact with it. Most people learn about Ethereum through the client (for example, using Geth,parity or Web3 via Metamask). Although these Ethereum clients implement the Ethereum protocol, they do not define it. In order for

1. Purpose
You may have installed SharePoint 2010 to configure a single server farm. This mode can meet the general requirements of small and medium websites. In practical applications, because large and medium-sized websites have high performance requirements, it is often necessary to build small and medium server farms that work collaboratively with multiple servers to meet customers'
