I tried the following code to find the actual behavior of this and related properties: // create list of types to use later in a Dictionary<,> var li = new List < Type >(); // two concrete types: li . Add ( typeof ( int )); li . Add ( typeof ( string )); // the two type parameters from Dictionary<,> li . Add ( typeof ( Dictionary <,>). GetGenericArguments ()[ 0 ]); li . Add ( typeof ( Dictionary <,>). GetGenericArguments ()[ 1 ]); //

I've checked the vertex and texture coordinates and they look fine to me. My texture is a power of 2. It is a texture map containing 4x4 textures in which each texture is 16x16 pixels. Does anyone have any suggestions? 回答1: I guess you are experiencing texture bleeding. You can solve it by either using GL_CLAMP on your textures or adjusting slightly your UV coordinates to 0.0005 and 0.0095 (for instance) instead of 0 and 1 to compensate for the texture sampling

How to query Hyperledger Fabric blockchain data outside CLI container?

I would like to invoke and query data from a PHP website from the blockchain. I do know that I can only use the API call from CLI container or use a JavaSDK/NodeSDK, RESTapi. How can I query data from the blockchain the easiest way? I am looking at NodeSDK and RestApi but I don't see much guides out there to help me, hence this question. Sorry for the newbie questions. Thanks! 回答1: The proper way to call and interact with Hyperledger Fabric peers is via

For this i found in the spring cloud stream reference documentation, autoCommitOffset Whether to autocommit offsets when a message has been processed. If set to false, an Acknowledgment header will be available in the message headers for late acknowledgment. Default: true. My question is after setting autoCommitOffset to false, how can i acknowledge a message? A Code example would be hugely

智能合约,是一个抽象的概念,智能合约的历史可以追溯到 1990s 年代。它是由尼克萨博(Nick Szabo)提出的理念,几乎与互联网同龄。 我们这里所说的智能合约只狭义的指区块链中。它能够部署和运行在区块链环境中,由 一段代码 来 描述 相关的 业务逻辑 。部署后的智能合约在区块链中 无法修改 ,智能合约的执行完全由代码决定,不受人为因素的干扰。一般来说,参与方通过 智能合约 规 定 各自 权利和义务 、 触发合约的条件 以及 结果 ,一旦该智能合约在 区块链环境 中运行就可以得出 客观 、 准确 的结果。 什么是ChainCode   ChainCode(链码)是智能合约在Fabric区块链网络的实现形式。分为 用户链码 和 系统链码 ,通常指的是用户链码。链码是 访问账本 的 基本方法 ,一般是用 Go 等高级语言编写的、 实现规定接口的代码 。上层 应用 可以通过 调用链码 来 初始化和管理账本的状态 。只要有适当的 权限 , 链码 之间也可以 互相调用 。   链码被部署在Fabric网络节点上,运行在隔离沙盒(目前为Docker容器)中,并通过gRPC协议与相应的Peer节点进行交互,以操作分布式账本中的数据。   启动Fabric网络后,可以通过命令行或SDK进行链码操作,验证网络运行是否正常。   它扮演的角色如下图所示:

Knowledge Graph - Wikipedia https://en.wikipedia.org/wiki/Knowledge_Graph The Knowledge Graph is a knowledge base used by Google and its services to enhance its search engine 's results with information gathered from a variety of sources. The information is presented to users in an infobox next to the search results. Knowledge Graph infoboxes were added to Google's search engine in May 2012, starting in the United States, with international expansion by the end of the year.

Changing edge attributes in networkx multigraph

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: In a multigraph each call to *add_edge(a,b,weight=1)* will add a new edge between nodes a and b . When building the graph, is it possible to modify this weight when a and b are found again. Right now I make a check to find whether (a, b) or (b, a) are connected, then have to delete the edge, and add a new one. It seems to me that I should simply be able to update the weight. Note: I do need multigraphs because I use different types of edges between nodes (differentiated using key ) 回答1: The Multigraph.add_edge documentation indicates that
