问题 I need to implement following behavior: when server starts, it should check for existing servers using broadcast. Then it waits for answer. But, how to set any timeout for waiting? int optval = 1; char buff[BUFF_SIZE]; SOCKADDR_IN addr; int length = sizeof(addr); if (setsockopt(s, SOL_SOCKET, SO_BROADCAST, (char*)&optval, sizeof(optval)) == SOCKET_ERROR) throw(errors::SETSOCKOPT); addr->sin_family = AF_INET; addr->sin_port = htons(this->serverPort); addr->sin_addr.s_addr = INADDR_ANY; sendto

问题 Having not found a 'boost' way of resetting an accumulator in C++, I came across a piece of code that seems to reset a boost accumulator. But don't understand how it is achieving it. The code is as below - #include <iostream> #include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics/stats.hpp> #include <boost/accumulators/statistics/mean.hpp> using namespace boost::accumulators; template< typename DEFAULT_INITIALIZABLE > inline void clear( DEFAULT_INITIALIZABLE&

问题 I'm trying to use the "LocalApi" feature of IdentityServer4 with some custom Policies. I have an API (hosted on the same application instance as IdentityServer4) that is divided into three parts (Server, Manager, Product) and for three clients (Server, Manager, Product). Client can only call the devoted part of the API and I would do this with Policies based on scopes. So I have the following: Starup: services.AddLocalApiAuthentication(); // Add API hosted on same application than

问题 I have a variety of elasticsearch indices which are created daily by logstash with the format: "logstash-%{cluster_type}-%{cluster_name}-jobaccounting-v2-%{+YYYY.MM.dd}" I would like to create an alias in elasticsearch which drops the version number from the index name. I am planning to point my kibana instance at the aliased index rather than the versioned index so that I can change the version numbers without impacting kibana. index: "logstash-%{cluster_type}-%{cluster_name}-jobaccounting

问题 I would like to wait until a for loop is finished to continue with my function. I can't seem to get it to work. Hello is always logged before the for loop finishes. Why is this, and what would be a way to run only when the for loop has finished. I need to wait for the for loop to finish before continuing within the function, but outside the for loop. I want to know how to wait until a for loop is finished, and then execute code. Not set timeouts within the for loop. function doMergeAnimations

问题 I already tried different things to get a list of mails from my inbox folder in Thunderbird. let page = await browser.messages.list(folder); But how to declare folder ? MailFolder is explained in Thunderbird Docs, but how do i get accountId (string) The account this folder belongs to. path (string) Path to this folder in the account. Although paths look predictable, never guess a folder’s path, as there are a number of reasons why it may not be what you think it is. [name] (string) The human

问题 I have the following code below which simply plots datasets (consisting of dogs and cats images) and their labels. I'm using jupyter notebook: train_path = 'dataset/train' valid_path = 'dataset/valid' test_path = 'dataset/test' train_batches = ImageDataGenerator().flow_from_directory(train_path, target_size=(224,224), classes=['dog', 'cat'], batch_size=10) valid_batches = ImageDataGenerator().flow_from_directory(valid_path, target_size=(224,224), classes=['dog', 'cat'], batch_size=4) test

问题 I am writing a small Python script to find time available slots based off calendar appointments. I was able to reuse the code on the post here: (Python - Algorithm find time slots). It does seem to work for booked appointments an hour or longer, but for those less than an hour it doesn't seem to catch them. In other words, it shows time slots as available even though appointments are booked (less than an hou). Sample code below from post mentioned, with my own values for "hours" and
