What's the main difference between bidirectional and directional sockets?

问题 Bidirectional means the data incoming and outgoing data flows over the same channel (sockets), in classical socket it is the case. For example you want to connect to a server: you create a socket, send and receive the data over the same channel. Is that not bidirectional? What's different to websockets (bidirectional), only that they are runnable on browsers? Is that the difference? Another question is what happens during bind() on serverside; is this used to say to the TCP-Stack

Mapping a bidirectional list with Hibernate

问题 I don't understand the behavior of Hibernate when mapping a bidirectional list. The SQL statements that Hibernate produces seem not optimal to me. Can somebody enlighten me? The scenario is the following: I have a one-to-many parent-child relationship. I map this relationship with a bidirectional list. According to the Hibernate Annotation Reference Guide (Chapter: Bidirectional association with indexed collections) the mapping should look like this: @Entity public class Parent { @Id

How to use multilayered bidirectional LSTM in Tensorflow?

I want to know how to use multilayered bidirectional LSTM in Tensorflow. I have already implemented the contents of bidirectional LSTM, but I wanna compare this model with the model added multi-layers. How should I add some code in this part? x = tf.unstack(tf.transpose(x, perm=[1, 0, 2])) #print(x[0].get_shape()) # Define lstm cells with tensorflow # Forward direction cell lstm_fw_cell = rnn.BasicLSTMCell(n_hidden, forget_bias=1.0) # Backward direction cell lstm_bw_cell = rnn.BasicLSTMCell(n_hidden, forget_bias=1.0) # Get lstm cell output try: outputs, _, _ = rnn.static_bidirectional_rnn(lstm

How do you use a Bidirectional BFS to find the shortest path?

问题 How do you use a Bidirectional BFS to find the shortest path? Let's say there is a 6x6 grid. The start point is in (0,5) and the end point is in (4,1). What is the shortest path using bidirectional bfs? There are no path costs. And it is undirected. 回答1: How does Bi-directional BFS work? Simultaneously run two BFS's from both source and target vertices, terminating once a vertex common to both runs is discovered. This vertex will be halfway between the source and the target. Why is it better

Why is it better than BFS? Bi-directional BFS will yield much better results than simple BFS in most cases. Assume the

Enforce invariants spanning multiple aggregates (set validation) in Domain-driven Design

偶尔善良 提交于 2019-12-02 07:11:30
To illustrate the problem we use a simple case: there are two aggregates - Lamp and Socket . The following business rule always must be enforced: Neither a Lamp nor a Socket can be connected more than once at the same time. To provide an appropriate command we conceive a Connector -service with the Connect(Lamp, Socket) -method to plug them. Because we want to comply to the rule that one transaction should involve only one aggregate, it's not advisable to set the association on both aggregates in the Connect -transaction. So we need an intermediate aggregate which symbolizes the Connection

Drawing Hebrew text to and image using Image module (python)

最后都变了- 提交于 2019-12-02 01:27:07
This is an issue I already asked about and several got answers but the problem remained. when I try to write in hebrew to an image using Image module I get instead of the hebrew lettring some other (ascii??) lettering. if I convert to unicode or ascii I get an error that it doesn't support. I got here a reference to a code that does what I want in chinese: import sys import Imag import ImageDraw import ImageFont import _imaging txt = '你好,世界!' font = ImageFont.truetype('c:/test/simsun.ttc',24) im = Image.new("RGBA",(300,200),(0,0,0)) draw = ImageDraw.Draw(im) #draw.text( (0,50), u'你好,世界!', font
