How do I use Google Speech API to access a file in Google Cloud Storage?

由 倖福魔咒の 提交于 2019-12-11 17:24:47
问题 I am using Visual Studio 2019 on Windows 10 for a .NET Console C# project using Google Speech API. I have the following code: class Program { static void Main(string[] args) { var URI = "https://speech.googleapis.com/v1/speech:recognize?key=AIzaSyANbpQ1iy-Ced72r7xgPVHuNZI5FAVIPjY&audio=audio.flac"; Console.WriteLine("Start!"); AsyncRecognizeGcs(URI); Console.WriteLine("End."); } static object AsyncRecognizeGcs(string storageUri) { var speech = SpeechClient.Create(); var longOperation = speech

Difference between Invoke-Command and query directly

由 强颜欢笑 提交于 2019-12-11 14:25:12
问题 I'm currently working on a script that queries the disk information from a server. I'm stack with a problem and I really don't know whats going on here. May you can help me. The following code is working (ComputerName replaced): $space1 = Invoke-Command -ComputerName "xxxxxx" -ScriptBlock { Get-WmiObject -Class Win32_LogicalDisk -Filter "DeviceID='C:'" } This code works kinda well and may takes around 2 seconds to execute. After some experimenting I found a way how I can query it even faster.

GWT-RPC, Apache, Tomcat server data size checking

由 ∥☆過路亽．° 提交于 2019-12-11 14:24:54
问题 Following up on this GWT-RPC question (and answer #1) re. field size checking, I would like to know the right way to check pre-deserialization for max data size sent to server, something like if request data size > X then abort the request . Valuing simplicity and based on answer on aforementioned question/answer, I am inclined to believe checking for max overall request size would suffice, finer grained checks (i.e., field level checks) could be deferred to post-deserialization, but I am

Client stub Vs Client socket & Server stub Vs Server socket

由 我与影子孤独终老i 提交于 2019-12-11 14:13:31
问题 Background Any client socket program(C) over TCP/IP looks like, /* Socket creation */ sockfd = socket(AF_INET, SOCK_STREAM, 0); /* Do nothing for dynamic address assignment to that client socket */ /* Identify the server, we use to send a request for connection */ bzero(&servaddr, sizeof(servaddr)); servaddr.sin_family = AF_INET; servaddr.sin_port = htons(8000); inet_pton(AF_INET, serv_ip, &servaddr.sin_addr); /* Connect request to listening socket of server */ ret_val = connect(sockfd,

Dubbo框架，SOA思想,Zookeeper安装

SOA思想 SOA介绍 面向服务的架构（SOA）是一个组件模型，它将应用程序的不同功能单元（称为服务）进行拆分，并通过这些服务之间定义良好的接口和契约联系起来。接口是采用中立的方式进行定义的，它应该独立于实现服务的硬件平台、操作系统和编程语言。这使得构建在各种各样的系统中的服务可以以一种统一和通用的方式进行交互。 RPC协议 RPC是远程过程调用（Remote Procedure Call）的缩写形式。SAP系统RPC调用的原理其实很简单，有一些类似于三层构架的C/S系统，第三方的客户程序通过接口调用SAP内部的标准或自定义函数，获得函数返回的数据进行处理后显示或打印。 HTTP协议与RPC的关系 层级关系与对应的协议. 区别 : 1.RPC是传输层协议(4层).而HTTP协议是应用层协议(7层). 2.RPC协议可以直接调用中立接口,HTTP协议不可以. 3.RPC通信协议是长链接,HTTP协议一般采用短连接需要3次握手(可以配置长链接添加请求头Keep-Alive: timeout=20). (长连接，指在一个连接上可以连续发送多个数据包，在连接保持期间，如果没有数据包发送，需要双方发链路检测包。) 4.RPC协议传递数据是加密压缩传输.HTTP协议需要传递大量的请求头信息. 5.RPC协议一般都有注册中心.有丰富的监控机制. dubbo Dubbo(读音[ˈdʌbəʊ]

Remote Procedure Call between Java and C

由 爱⌒轻易说出口 提交于 2019-12-11 11:54:24
问题 I'm looking for a way to implement RPC between Java and C. What are the options to do this? Best Wishes p.s I have web java application which is hosted on Glassfish server and C daemon. I need to directly call functions from bought sides. 回答1: The whole point of RPC is to let two opaque processes on different systems talk to each other over a network. The languages used are irrelevant, except that you have to learn the corresponding RPC libraries for both languages. 回答2: Google Protocol

Simultaneous gRPC clients sync/async server

由 不羁岁月 提交于 2019-12-11 10:59:46
问题 I'm just curious, Does a sync gRPC server supports connection from multiples clients? If not, and the async ones does? And combination of async server/sync client? is even possible? 回答1: Yes, synchronous gRPC supports multiple connected clients out of the box. I have personally tested with up to 2000 simultaneously connected clients to an microservice written in Go exposing a single API. 来源： https://stackoverflow.com/questions/45486733/simultaneous-grpc-clients-sync-async-server

Alternatives to RMI for IPC?

由 穿精又带淫゛_ 提交于 2019-12-11 06:31:58
问题 I have 2 processes that need to communicate over the same PC and different PCs. In the local case the process communication is among different processes e.g Process A and Process B . In the remote case it will be among 2 instances of Process A running in different PCs. I will create them from scratch and I am wondering what is the best approach. I am aware of RMI and sockets but I was wondering for my case as described, and taking also into account that the messages exchanged are small and

BOOST ASIO multi-io_service RPC framework design RFC

由 安稳与你 提交于 2019-12-11 05:29:49
问题 I am working on a RPC framework, I want to use a multi io_service design to decouple the io_objects that perform the IO (front-end) from the the threads that perform the RPC work (the back-end). The front-end should be single threaded and the back-end should have a thread pool. I was considering a design to get the front-end and back-end to synchronise using a condition variables. However, it seems boost::thread and boost::asio do not comingle --i.e., it seems condition variable async_wait
